Tracking the Enemy: U.S. Space Force in Qatar

The newly formed U.S. Space Force is deploying troops to a vast new frontier: the Arabian Peninsula. Space Force now has a squadron of 20 airmen stationed at Qatar’s Al-Udeid Air Base in its first foreign deployment. The force, pushed by President Donald Trump, represents the sixth branch of the U.S. military and the first new military service since the creation of the Air Force in 1947.   Concerns over the weaponization of outer space are decades old. But as space becomes increasingly contested, military experts have cited the need for a space corps devoted to defending American interests…

In the spring of 2020, Iran’s paramilitary Revolutionary Guard launched its first satellite into space, revealing what experts describe as a secret military space program. The Trump administration has imposed sanctions on Iran’s space agency, accusing it of developing ballistic missiles under the cover of a civilian program to set satellites into orbit.

“The military is very reliant on satellite communications, navigation and global missile warning,” said Capt. Ryan Vickers, a newly inducted Space Force member at Al-Udeid. American troops, he added, use GPS coordinates to track ships passing through strategic Gulf passageways…

A Perpetual State of Competition: US-China-Russia

The US Secretary of Defense stated in September 2020 that America’s air, space and cyber warriors “will be at the forefront of tomorrow’s high-end fight.” That means confronting near-peer competitors China and Russia. That means shifting the focus from defeating violent extremist groups to deterring great power competitors. It means fighting a high-intensity battle that combines all domains of warfare. “In this era of great power competition, we cannot take for granted the United States’ long-held advantages,” Esper said. 

The last time an enemy force dropped a bomb on American troops was in the Korean War. “China and Russia, seek to erode our longstanding dominance in air power through long-range fires, anti-access/area-denial systems and other asymmetric capabilities designed to counter our strengths,” he said. “Meanwhile, in space, Moscow and Beijing have turned a once peaceful arena into a warfighting domain.” China and Russia have placed weapons on satellites and are developing directed energy weapons to exploit U.S. systems “and chip away at our military advantage,” he said.

Russia, China, North Korea, Iran and some violent extremist groups also look to exploit cyberspace to undermine U.S. security without confronting American conventional overmatch. “They do this all in an increasingly ‘gray zone’ of engagement that keeps us in a perpetual state of competition,’ the secretary said…The fiscal 2020 Defense Department research and development budget is the largest in history, he said, and it concentrates on critical technologies such as hypersonic weapons, directed energy and autonomous systems. 

“In the Air Force, specifically, we are modernizing our force for the 21st century with aircraft such as the B-21, the X-37 and the Next Generation Air Dominance platform,” Esper said. “Equally important, we are transforming the way we fight through the implementation of novel concepts such as Dynamic Force Employment, which provides scalable options to employ the joint force while preserving our capabilities for major combat.”

To realize the full potential of new concepts the department must be able to exchange and synchronize information across systems, services and platforms, seamlessly across all domains, he said. “The Department of the Air Force is leading on this front with the advancement of Joint All-Domain Command and Control,” Esper said.  This concept is part of the development of a Joint Warfighting concept that will drive transition to all-domain operations, he said. “

For these breakthroughs to succeed in any future conflict … we must maintain superiority in the ultimate high ground — space,” Esper said…In collaboration with academia and industry, the Air Force’s AI Accelerator program is able to rapidly prototype cutting-edge innovation,” Esper said. One example of this was the AI technology used to speed-up the development of  F-15EX.

Poker and Blackjack: How to Make War in Space

In March 2018, India became only the fourth country in the world—after Russia, the US, and China—to successfully destroy a satellite in orbit. Mission Shakti, as it was called, was a demonstration of a direct-ascent anti-satellite weapon (ASAT)—or in plain English, a missile launched from the ground. Typically this type of ASAT has a “kill vehicle,” essentially a chunk of metal with its own guidance system, mounted on top of a ballistic missile. Shortly after the missile leaves the atmosphere, the kill vehicle detaches from it and makes small course corrections as it approaches the target. No explosives are needed; at orbital speeds, kinetic energy does the damage…. China’s own first successful ASAT test was in 2007….

But going to war in space… doesn’t necessarily mean blowing up satellites. Less aggressive methods typically involve cyberattacks to interfere with the data flows between satellites and the ground stations.  Satellites are, after all, computers that happen to be in space, so they are vulnerable to attacks that disable or hijack them, just like their terrestrial peers.

For example, in 2008, a cyberattack on a ground station in Norway let someone cause 12 minutes of interference with NASA’s Landsat satellites. Later that year, hackers gained access to NASA’s Terra Earth observation satellite and did everything but issue commands. It’s not clear if they could have done so but chose not to. Nor is it clear who was behind the attack, although some commentators at the time pointed the finger at China. Experts warn that hackers could shut off a satellite’s communications, rendering it useless. Or they could permanently damage it by burning off all its propellant or pointing its imaging sensor at the sun to burn it out.

Another common mode of attack is to jam or spoof satellite signals. There is nothing fancy about this: it’s easier than hacking, and all the gear required is commercially available.  Jammers, often mounted on the back of trucks, operate at the same frequency as GPS or other satellite communication systems to block their signals. …There are strong suspicions that Russia has been jamming GPS signals during NATO exercises in Norway and Finland, and using similar tactics in other conflicts. “Russia is absolutely attacking space systems using jammers throughout the Ukraine,” says Weeden. Jamming is hard to distinguish from unintentional interference, making attribution difficult (the US military regularly jams its own communications satellites by accident). A recent report from the US Defense Intelligence Agency (DIA) claims that China is now developing jammers that can target a wide range of frequencies, including military communication bands. North Korea is believed to have bought jammers from Russia, and insurgent groups in Iraq and Afghanistan have been known to use them too.

Spoofing, meanwhile, puts out a fake signal that tricks GPS or other satellite receivers on the ground…. Russia also seems to use spoofing as a way of protecting critical infrastructure,,,.As well as being hard to pin on anyone, jamming and spoofing can sow doubt in an enemy’s mind about whether they can trust their own equipment when needed. The processes can also be switched off at any time, which makes attribution even harder.

The 2019 Defense Intelligence Agency (DIA) report suggests that China will have a ground-based laser that can destroy a satellite’s optical sensors in low Earth orbit as early as next year (and that will, by the mid-2020s, be capable of damaging the structure of the satellite). Generally, the intention with lasers is not to blast a satellite out of the sky but to overwhelm its image sensor so it can’t photograph sensitive locations. The damage can be temporary, unless the laser is powerful enough to make it permanent…In 2006, US officials claimed that China was aiming lasers at US imaging satellites passing over Chinese territory.

“It’s happening all the time at this low level,” says Harrison. “It’s more gray-zone aggression. Countries are pushing the limits of accepted behavior and challenging norms. They’re staying below the threshold of conflict.”..

The suspicion is that China is practicing for something known as a co-orbital attack, in which an object is sent into orbit near a target satellite, maneuvers itself into position, and then waits for an order. Such exercises could have less aggressive purposes—inspecting other satellites or repairing or disposing of them, perhaps. But co-orbiting might also be used to jam or snoop on enemy satellites’ data, or even to attack them physically….Russia, too, has been playing about in geostationary orbit. One of its satellites, Olymp-K, began moving about regularly, at one point getting in between two Intelsat commercial satellites. Another time, it got so close to a French-Italian military satellite that the French government called it an act of “espionage.” The US, similarly, has tested a number of small satellites that can maneuver around in space.

As the dominant player in space for decades, the US now has the most to lose. The DIA report points out that both China and Russia reorganized their militaries to give space warfare a far more central role. In response, the US military is starting to make satellites tougher to find and attack. For instance, the NTS-3, a new experimental GPS satellite scheduled for launch in 2022, will have programmable, steerable antennas that can broadcast at higher power to counter jamming. It’s designed to remain accurate even if it loses its connection with ground controllers, and to detect efforts to jam its signal.

Another solution is not just to make single satellites more resilient, but to use constellations in which any one satellite is not that important. That’s the thinking behind Blackjack, a new DARPA program to create a cheap network of military communications satellites in low Earth orbit.

If You Control Space, You Control Everything: Space as War Domain

The North Atlantic Treaty Organization (NATO) is looking to classify space as a domain for warfare in an attempt to deter China’s growing military power.  If NATO’s proposal succeeds, the international alliance could move forward with the development and use of space weapons.  According to NATO diplomats, the international organization is preparing to release an agreement that will officially declare space as a war domain. This means that aside from land, air and sea, space could also be used for military operations during times of war.

Although NATO’s partner countries currently own 65% of the satellites in space, China is reportedly preparing to launch a massive project that involves releasing constellations of satellites in low Earth orbit.  China Aerospace Science and Industry Corp (CASIC)  is planning to put in orbit 150 or more Hongyun satellites by 2023. Some of these satellites will provide commercial services like high-speed internet while others would be controlled by the Chinese military. These militarized satellites can be used to coordinate ground forces and to track approaching missiles.

“You can have warfare exclusively in space, but whoever controls space also controls what happens on land, on the sea and in the air,” according to Jamie Shea, a former NATO official. “If you don’t control space, you don’t control the other domains either.”

Killing Machines: Tiny Spy Satellites

As long as we’ve been launching spy satellites into space, we’ve been trying to find ways to hide them from the enemy. Now, thanks to the small satellite revolution—and a growing amount of space junk—America has a new way to mask its spying in orbit…

The National Reconnaissance Office, the operator of many of the U.S.’s spy sats, refused to answer any questions about ways to hide small satellites in orbit.  In 2014, Russia launched a trio of communications satellites. Like any other launch, spent stages and space debris were left behind in space. Air Force Space Command dutifully catalogued them, including a nondescript piece of debris called Object 2014-28E.  Nondescript until it started to move around in space, that is. One thing about orbits; they are supposed to be predictable. When something moves in an unexpected way, the debris is not debris but a spacecraft. And this object was flying close to the spent stages, maneuvering to get closer.  This fueled speculation that the object could be a prototype kamikaze-style sat killer. Other less frantic speculation postulated that it could be used to examine other sats in orbit, either Russia’s or those operated by geopolitical foes. Either way, the lesson was learned…

Modern tracking radar is supposed to map space junk better than ever before. But small spy satellites that will hide in the cloud of space debris may go undetected, even by the most sophisticated new radar or Earth-based electronic signals snooping.

The 500 Cases of Marine Pollution

An international law enforcement operation against maritime pollution has revealed hundreds of violations and exposed serious cases of contamination worldwide.  Codenamed 30 Days at Sea, the month-long (1-31 October) operation saw some 276 law enforcement and environmental agencies across 58 countries detect more than 500 offences, including illegal discharges of oil and garbage from vessels, shipbreaking, breaches of ship emissions regulations, and pollution on rivers and land-based runoff to the sea.  More than 5200 inspections have resulted in at least 185 investigations, with arrests and prosecutions anticipated.

“Criminals believe marine pollution is a low-risk crime with no real victims.  This is a mistake and one which INTERPOL and our partners are addressing as demonstrated by this operation,” said INTERPOL Secretary General Jürgen Stock.  Cases of serious contamination included the dumping of animal farm waste in Philippine coastal waters where local communities collect shellfish and children play.  In Germany, a vessel discharged 600 litres of palm oil into the sea. Ghana uncovered gallons of waste oil in large bottles thought to be illegally dumped at sea.  Authorities prevented an environmental disaster in Albania by securing waters around a sinking vessel containing some 500 litres of oil. Similarly, the pollution threat resulting from the collision of two ships in French waters was contained thanks to preventive action during the operation.

Innovative technologies permitted authorities to detect offences, including the use of satellite images (in Argentina and Sweden), aerial surveillance (Canada and Italy), drones (Nigeria, Indonesia and Pakistan) and night vision cameras.

The First to Shoot…from Space

North Korea’s preparations to launch a more advanced reconnaissance satellite with a high-resolution scanning capability threaten to push Asia’s space race deeper into the military theater.  The Kwangmyongsong-5 Earth-exploration satellite, likely to be packaged with a separate communications satellite, will technically allow North Korea to transmit data down to the ground for the first time, thus offering real-time intelligence for potential ballistic-missile strikes.

This is well short of the technological capacity needed to deploy orbital weapon systems, but will cause some unease among Asian power-brokers China, Japan and India as they pour money into the last strategic frontier of outer space.  Space programs in Asia have largely been driven by competition for the US$300 billion global commercial transponders market, which is expected to double by 2030 if demand holds.

A shift toward miniature satellites of less than 20 kilograms, mostly used by governments and smaller companies, has drawn nations as diverse as Singapore, Pakistan, Vietnam and South Korea into a field led by Japan and China, with India a more recent player.

Japan placed two satellites in different orbits for the first time on December 2017, displaying a technical edge aimed at reducing launch costs for commercial clients. India announced this week that it had successfully tested a GSLV Mark III rocket that can lift a 4-ton satellite into orbit. In 2017, it managed to launch 104 satellites of varying sizes in just one operation. China has loftier ambitions, including a lunar landing some time in 2018, after sending a roving module down a steep crater on the moon in 2013. About 40 Chinese launches are likely in 2018, mainly to boost communications.  India and Japan are both locked in undeclared space races with China that go well beyond commercial rivalries and have muddied the debate over North Korea’s shadowy aims….

“Militarization” refers to any systems that enhance the capability of forces in a conventional setting, such as intelligence, communications and surveillance. “Weaponization” is the physical deployment of weapons in outer space or in a ground mode where they can be used to attack and destroy targets in orbit.  The United Nations Treaty on Outer Space prohibits the deployment of weapons of mass destruction in space, but the US has blocked efforts to ban space weapons outright. In 2007, Washington said it would “preserve its rights, capabilities, and freedom of action in space.”

SpaceX Falcon

A SpaceX Falcon rocket lifted off from the Kennedy Space Center in Florida on May , 2017 to boost a classified spy satellite into orbit for the U.S. military, then turned around and touched down at a nearby landing pad.

It was the 34th mission for SpaceX, but its first flight for the Department of Defense, a customer long-pursued by company founder Elon Musk. The privately owned SpaceX once sued the Air Force over its exclusive launch services contract with United Launch Alliance (ULA), a partnership of Lockheed-Martin and Boeing.)  The liftoff of a classified satellite for the National Reconnaissance Office (NRO) officially broke ULA’s 10-year monopoly on launching U.S. military and national security satellites.

In addition to the NRO’s business, SpaceX has won two Air Force contracts to launch Global Positioning System satellites in 2018 and 2019.  For now, the military’s business is a fraction of more than 70 missions, worth more than $10 billion, slated to fly on SpaceX rockets. But with up to 13 more military satellite launches open for competitive bidding in the next few years and ULA’s lucrative sole-source contract due to end in 2019, SpaceX is angling to become a majo launch service provider to the Department of Defense.

A month ago, SpaceX for the first time launched one of its previously flown rockets to send an SES communications satellite into orbit, a key step in Musk’s quest to demonstrate reusability and slash launch costs.

Small Satellites-Big Data

Built by the Indian Space Research Organisation, the Polar Satellite Launch Vehicle threw itself into the sky at 3.58am GMT on February 15th, 2017 It took with it a record-breaking 104 satellites—88 of which belonged to a single company, Planet, a remote sensing business based in San Francisco. Planet now has 149 satellites in orbit—enough for it to provide its customers with new moderately detailed images of all the Earth’s land surface every single day.  The satellites Planet makes—it calls them “doves”—measure 10cm by 10cm by 30cm.

Providing daily updated images of the earth is not enough… Processing the images to answer pressing questions: what has changed since yesterday? Is that illegal logging? What does the number of containers in these ports suggest about trade balances? Planet will be providing more such analysis itself, but there are also third parties eager to play. SpaceKnow, a startup which focuses on turning satellite data into analysis the financial community will pay for, has just raised $4m….

Planet is not the only company using small satellites to produce big data; the launch on February 15th also carried up eight ship-tracking satellites owned by Spire, just a couple of streets away from Planet. The companies hope that, as more and more customers come to see the value of an endlessly updated, easily searchable view of the world, insights from satellites will become ever more vital to the data-analysis market. The more normal their wares start to seem, the more spectacular their future may be

Kidnapper Satellites: war in space

It was May 2014 when a small team of American airmen monitoring a Russian satellite launch saw something they had never seen before. An object the team thought was a piece of debris from the launch suddenly came to life.  “The one object that we assumed was a piece of debris started to maneuver in close proximity to the (rocket) booster,” recalled Lt. Gen. David Buck …at Vandenberg Air Force Base in California. Buck… said the deliberate maneuvers the mystery object made close to the rocket’s booster were a red flag. Getting that close to another object in space is a complex feat, as objects can move as fast as 17,500 miles per hour….[W]hat the US military was witnessing was not debris at all, but instead a satellite with a dangerous capability, one that could allow it to cozy up next to another satellite and potentially destroy it….

The Russian satellite is officially known as Kosmos 2499 but it has been given a more daunting nickname: “kamikaze,” a spacecraft expressly designed to maneuver up close to another satellite to disable or destroy it. In other words, it’s a satellite that could go on the attack.Retired Gen. William Shelton, the former commander of Air Force space command, likened the satellite to a space Trojan horse. “You could have something on orbit that, for all intents and purposes, looks like a communications satellite, when in actuality, it is also a weapon,” said Shelton.

Kosmos 2499 is far from the only threat. In September 2014, just a few months after Kosmos was placed in orbit, Russia launched an additional satellite named Luch with both maneuvering and spying capabilities.  “This satellite has been maneuvering through geosynchronous space … cozying up close to various communications satellites, listening to what traffic is flowing over those,” said Paul Graziani, CEO of civilian satellite tracker Analytical Graphics, Inc. (AGI).

Over the course of a year, Graziani’s team has watched as Luch parked itself next to three US commercial satellites and one European satellite. The Russians flew the satellite close enough to collect both civilian and, possibly, sensitive military information.  Graziani was charged with delivering the bad news to US-owned commercial satellite company Intelsat…

“If the operators of this spacecraft so chose, they could direct it to actually hit another spacecraft,” said Graziani.  Like Kosmos, Luch’s ability to maneuver has the potential to make it into a satellite killer.

 Launched in 2013, the Shiyan, meaning “experiment” in Chinese, was “experimenting” shadowing the smaller satellite, according to AGI. But then something unexpected happened: The smaller satellite repeatedly disappeared and then reappeared on their screens.“We saw the approach, we saw the larger spacecraft come close to the smaller spacecraft, and then we no longer saw the smaller spacecraft,” said Graziani.

The only reasonable explanation, experts say, is that the Shiyan has a robotic arm that was repeatedly grabbing and then releasing its smaller partner.  The Chinese government acknowledged the satellite’s robotic arm, saying the satellite is “mainly used in space debris observation,” according to the state-run Xinhua News Agency.

But space watchers like Graziani see a more sinister application.  “You could grab and hold of a satellite and maneuver it out of its mission,” said Graziani  If true, it would be a new threatening capability, allowing the Shiyan to essentially kidnap another satellite….

Lasers:  “You can aim a laser at a satellite’s sensor and try to make it hard to see,” said Laura Grego, a scientist with the Union of Concerned Scientists. “Like someone shining a flashlight in your eyes.”With power dialed up high that same laser could permanently fry the satellite’s sensor. But “very expensive and important satellites should have shutters” to block this kind of threat, said Grego, who considers these types of activities more of a nuisance than a space attack.

Space drone: Moving further into the realm of science fiction, the US military has developed the first space drone, the X-37B. Bearing a striking resemblance to the space shuttle, the drone is officially a reusable spacecraft for carrying payloads into space…Its other missions are classified, but the drone’s maneuverability, payload space and ability to stay in orbit for hundreds of days have space watchers and countries like Russia and China wondering whether the X-37B would one day be used as a space fighter jet,

The Quiet Revolution in Space

National security critically depends on space, and the Defense Advanced Research Projects Agency (DARPA) is focused today on creating the capabilities needed to help make that environment a real-time operational domain, DARPA Director Dr. Arati Prabhakar…

“The questions we ask ourselves at DARPA about the space domain … is what would it take to make the space domain robust for everything that we need militarily and for intelligence, and what would it take to make space a real-time operational domain, which it’s not at all today,” the director said, noting that many other nation-states now are active in orbit and space is a domain where conflict is becoming a real possibility.

Through a national security lens, she added, nothing needed from an intelligence or military perspective can be done effectively without access to space. Something as simple as navigation completely depends on GPS in nearly every part of the world and in every operating regime.

In an era of declining budgets and adversaries’ evolving capabilities, quick, affordable and routine access to space is increasingly critical for national and economic security. Today’s satellite launch systems require scheduling years in advance for a limited inventory of available slots and launches often cost hundreds of millions of dollars each. The Defense Advanced Research Projects Agency created its Experimental Spaceplane, or XS-1, program to help overcome these challenges and reduce the time to get capabilities to space. DARPA artist-concept graphics  “Because of the demands on launch, from the day you know you have to put an asset on orbit to the time you can plan on a launch today is still unacceptably long,” Prabhakar said.

Commercial capabilities will help, she added, “but if in a time of war we imagine if we could go to space not in a month or next week but tomorrow, think about how that would completely change the calculus for an adversary that’s thinking about [using an antisatellite] weapon to take out one of our satellites

”With that ambition in mind, DARPA is now starting Phase 2 of its Experimental Spaceplane, or XS-1.“It’s a reusable first stage that’s designed to be able to put 3,000 or 5,000 pounds into low earth orbit … at a very low cost point — a few million dollars — but very significantly the objective on the DARPA program is by the end of the program to fly that spacecraft 10 times in 10 days,” Prabhakar said, “something that’s inconceivable with any of the spacecraft we have today.”

A second piece of the puzzle is what can be done in orbit, she added, referring to low earth orbit, or LEO, an orbit around Earth whose altitude is between 99 and 1,200 miles.

“We’re doing some amazing work with geo[synchronous]-robotics and rethinking [geostationary Earth orbit]-architectures once you have an asset that would allow you to extend the life or do inspection or simple repairs at GEO, which is something you can’t do today.  GEO [geostationary orbit]is a stable region of space 22,370 miles from Earth.  And because GEO is a stable environment for machines — but hostile for people because of high radiation levels — DARPA thinks the key technology there is space robotics.  DARPA’s Phoenix program seeks to enable GEO robotics servicing and asset life extension while developing new satellite architectures to reduce the cost of space-based systems.

The program’s goal is to develop and demonstrate technologies that make it possible to inspect and robotically service cooperative space systems in GEO and to validate new satellite assembly architectures. Phoenix has validated the concept that new satellites could be built on orbit by physically aggregating “satlets” in space, according to DARPA.

Satlets are small independent modules that can attach together to create a new low-cost, modular satellite architecture, DARPA says. Satlets incorporate essential satellite functionality — power supplies, movement controls, sensors and others — and share data, power and thermal management capabilities. DARPA now is working to validate the technical concept of satlets in LEO [Low earth orbit an orbit around Earth whose altitude is between 99 and 1,200 miles.]

China as a Space Achiever

China’s experimental space lab Tiangong-2 orbiting the Earth with two astronauts on board has successfully launched a micro-satellite, roughly the size of a desktop printer. Weighing 47 kilogrammes, the micro satellite has a series of visible light cameras, including a 25 megapixel camera and wide-angle imagers. Its mission is to take photographs of Tiangong II and the Shenzhou 11 spacecraft, which docked with the lab on Wednesday.

The Tiangong II space laboratory released its companion satellite, Banxing-2, at 7:31 am local time on October 23, 2016. The satellite, which the media has nicknamed “Selfie Stick”, also has an infrared camera that is temperature-sensitive…“Like a private nurse for Tiangong II and Shenzhou XI, the companion satellite monitors their conditions all the time, which is helpful in detecting failures”

How to Make Space Friendly for Military Use

From the DARPA website

The volume of Earth’s operational space domain is hundreds of thousands times larger than the Earth’s oceans. It contains thousands of objects hurtling at tens of thousands of miles per hour. The scales and speeds in this extreme environment are difficult enough to grasp conceptually, let alone operationally, as is required for commanders overseeing the nation’s increasingly critical space assets.

Current [US] space domain awareness tools and technologies were developed when there were many fewer objects in space. Only a few nations could even place satellites in orbit, and those orbits were easily predictable without advanced software tools. That situation has changed dramatically in the past decade with a developing space industry flooding once lonely orbits with volleys of satellite constellations. Despite this much more complex and chaotic environment, commanders with responsibility for space domain awareness often rely on outdated tools and processes—and thus incomplete information—as they plan, assess, and execute U.S. military operations in space.

To help address these technical and strategic challenges, DARPA is launching the first of two planned efforts under the Agency’s new Hallmark program, which has the overarching goal to provide breakthrough capabilities in U.S. space command and control. This first effort, the Hallmark Software Testbed (Hallmark-ST), has as its primary goal the creation of an advanced enterprise software architecture for a testbed for tools that will integrate a full spectrum of real-time space-domain systems and capabilities. The testbed would be used to expedite the creation and assessment of a comprehensive set of new and improved tools and technologies that could be spun off into near-term operational use for the Defense Department’s Joint Space Operations Center (JSpOC) and Joint Interagency Combined Space Operations Center (JICSpOC).

“For example, an intuitive user interface incorporating 3-D visualization technology would present complex information in novel ways and provide commanders with unprecedented awareness and comprehension. An advanced testbed featuring playback and simulation capabilities would significantly facilitate research and development activities, experiments, and exercises to evaluate new technologies for their impact on space command and control capabilities.”

The enterprise architecture would be the backbone of a long-term testbed, the Hallmark Space Evaluation and Analysis Capability (SEAC), anticipated to be located in Northern Virginia.

A Barbed Wire for Outer Space

In 2007 a missile launch by the Chinese in 2007 blew up a dead satellite and littered space with thousands of pieces of debris. But it was another Chinese launch  in 2013 that made the Pentagon really snap to attention, opening up the possibility that outer space would become a new front in modern warfare.  This time, the rocket reached close to a far more distant orbit — one that’s more than 22,000 miles away — and just happens to be where the United States parks its most sensitive national security satellites, used for tasks such as guiding precision bombs and spying on adversaries.

The flyby served as a wake-up call and prompted the Defense Department and intelligence agencies to begin spending billions of dollars to protect what Air Force Gen. John Hyten in an interview called the “most valuable real estate in space.”..[I]nstead of relying only on large and expensive systems, defense officials plan to send swarms of small satellites into orbit that are much more difficult to target–GPS III is the next generation of GPS satellites..

At the same time..[a]gencies have begun participating in war-game scenarios involving space combat at the recently activated Joint Interagency Combined Space Operations Center. The Pentagon is even developing what is known as the “Space Fence,” which would allow it to better track debris in space.

National security officials are not only concerned that missiles could take out their satellites but also that a craft’s equipment could be easily jammed. Potential enemies could “dazzle” sensors, temporarily blinding them, or deploy tiny “parasitic satellites” that attach to host satellites and do their worst. That could lead to soldiers stranded on the battlefield with little means of communication or missiles that would not be able to find their targets.  “We have considered space a sanctuary for quite some time. And therefore a lot of our systems are big, expensive, enormously capable, but enormously vulnerable,” said Deputy Defense Secretary Robert O. Work.

Pentagon officials say that Russia and China have been developing the capability to attack the United States in space…Pentagon officials fear its satellites could be sitting ducks. Navy Adm. Cecil Haney, commander of the U.S. Strategic Command, said recently that North Korea has successfully jammed GPS satellites, that Iran was busy building a space program and that “violent extremist organizations” were able to access space-based technologies to help them encrypt communications, among other things.

The Pentagon spends $22 billion on space programs and is investing an additional $5 billion in space efforts this year, including $2 billion for what is known as “space control,” which includes its highly classified offensive programs. Hyten declined to discuss the ways in which the United States is preparing to attack other countries in space. But the United States has had the capability to blow up satellites since 1985, when an F-15 fighter pilot fired a missile into space that took out an old military observation satellite.

Brazil as Space Power

The Brazilian government is ending a decade-long project to operate Ukraine’s Cyclone-4 rocket from Brazilian territory following a government review that found too many open questions about its cost and future market success, the deputy chief of the Brazilian Space Agency (AEB) said.  It remains unclear whether the decision will force Brazil to pay Ukraine any financial penalties for a unilateral cancellation of a bilateral agreement. Over the years, the work to build a launch facility for Ukraine’s Cyclone at Brazil’s Alcantara spaceport has suffered multiple stops and starts as one side or the other fell short on its financial obligations to the effort…

Noronha de Souza said the idea of making a profit in the launch business is now viewed as an illusion. The project, he said, was unlikely ever to be able to support itself on commercial revenue alone.  “Do you really believe launchers make money in any part of the world? I don’t believe so. If the government doesn’t buy launches and fund the development of technology, it does not work,” he said.  “Everybody talks about SpaceX [of Hawthorne, California] like it’s magic, somehow different. It’s no different. Their connections with NASA have been important. If NASA had stopped the funding, where would they be? I really appreciate what they are doing, but I doubt whether launch bases can make money and survive on their own without government support.”…

While the Cyclone-4 project is about to end, Brazil has maintained as a strategic goal the development of a space-launch vehicle from the Brazilian military-owned Alcantara facility. As such it is continuing work with the German Aerospace Center, DLR, on a small solid-fueled vehicle, called VLM-1 for Microsatellite Launch Vehicle, that began as a launcher for suborbital missions and has evolved to a small-satellite-launch capability…

AEB is a purely civilian agency funded through the Science and Technology Ministry. Until a few years ago, the Brazilian military had not been a player in the nation’s space policy. That is starting to change with the Brazilian Defense Ministry’s establishment of space-related operational requirements.  Among those requirements is a radar Earth observation satellite, which AEB has penciled into its program for around 2020. Aside from allowing the use of its Alcantara site, the Brazilian military is not yet financing any AEB work, but the military is expected to pay for launches of its satellites once the development is completed

AEB is finishing design of a small multimission satellite platform whose first launch will be of the Amazonia-1 Earth observation payload, with a medium-resolution imager of 10-meter-resolution, similar to the capacity of today’s larger China-Brazil CBERS-4 satellite, which is in orbit.

Brazil and Argentina’s CONAE space agency will be dividing responsibility for an ocean-observation satellite system, using the same multimission platform, called Sabia-Mar. The first Sabia-Mar is scheduled for launch in 2017, with a second in 2018, according to AEB planning.

Excerpts from Peter B. de Selding Brazil Pulling Out of Ukrainian Launcher Project,  Space News, Apr. 16, 2015

Russia has rushed to take advantage of the cancellation of space agreement between Brazil and Ukraine. [Russia] wants bot build  joint projects and space programs on the long term with BRICS Group member countries, particularly Brazil.  Brazil attempts to build its own cosmodrome, and unfortunately for the loss of Ukraine and its technology, the Brazilian-Ukrainian Project for the use of the Cyclone rocket in coastal launchings is practically minimalized…Russia proposed its variant of work, consisting in principle on the installation, already existent, of several satellite navigation stations Glonass and tbe idea of helping Brasilia in some way to the construction of the cosmodrome.

Space Conquest: DARPA Phoenix

The traditional process of designing, developing, building and deploying space systems is long and expensive. Satellites today cannot follow the terrestrial paradigm of “assemble, repair, upgrade, reuse,” and must be designed to operate without any upgrades or repairs for their entire lifespan—a methodology that drives size, complexity and ultimately cost. These difficulties apply especially to the increasing number of expensive, mission-critical satellites launched every year into geosynchronous Earth orbit (GEO), approximately 22,000 miles above the Earth. Unlike objects in low Earth orbit (LEO), such as the Hubble Space Telescope, satellites in GEO are essentially unreachable with current technology.

Advanced GEO space robotics: DARPA is developing a variety of robotics technologies to address key on-orbit mission needs, including assembly, repair, asset life extension, refueling, etc., in the harsh environment of geosynchronous orbit. Development activities include the maturation of robotic arms and multiple generic and mission-specific tools. …

Satlets: A new low-cost, modular satellite architecture that can scale almost infinitely. Satlets are small independent modules (roughly 15 pounds/7 kg) that incorporate essential satellite functionality (power supplies, movement controls, sensors, etc.). Satlets share data, power and thermal management capabilities. They also physically aggregate (attach together) in different combinations that would provide capabilities to accomplish a range of diverse space missions with any type, size or shape payload. Because they are modular, they can be produced on an assembly line at low cost and integrated very quickly with different payloads. DARPA is presently focused on validating the technical concept of satlets in LEO.

Payload Orbital Delivery (POD) system: The POD is a standardized mechanism designed to safely carry a wide variety of separable mass elements to orbit—including payloads, satlets and electronics—aboard commercial communications satellites.

Uncontacted Tribes: Amazon

The vast jungles of the Amazon rainforest harbor tribes mostly isolated from the outside world, whose way of life, largely unchanged for millennia, is now increasingly threatened by intrusions from modern civilization.  Now, scientists reveal they can monitor these “uncontacted tribes” using satellites, which would allow safe, inexpensive and noninvasive tracking of these tribes in order to protect them from outside threats.

The investigators focused on indigenous groups concentrated near the headwaters of the Envira River, located at the border of Brazil and Peru. These include the Mashco-Piro, nomadic hunter-gatherers who live in Peru’s densely forested Madre de Dios region, and a number of Pano-speaking farming societies.

The researchers combed through satellite images to look at five isolated villages previously identified via overflights by Brazilian officials. They confirmed these locations and measured the sizes of their villages, houses and gardens. The villages ranged from a small one of about 50 people to a large and growing village of about 300 people. “We can find isolated villages with remote sensing and study them over time,” Walker told Live Science. “We can ask: Are they growing? Do they move?”

Surprisingly, based on the sizes of the houses and villages, the scientists find the population densities of these isolated villages is about 10 times greater, on average, than other villages of indigenous Brazilian peoples….. The researchers now plan to focus on 29 more isolated villages….

The Space Belongs to Drones

Zephyr– high-altitude “pseudo-satellite” ( HAPS) —  is actually an unmanned, ultra-light, solar-powered, propeller-driven aircraft. But it is designed, just as some satellites are, to hover indefinitely over the same part of the world. With a 23-metre wingspan and a weight of only 50kg, it is fragile and must remain above the ravages of the weather and the jet stream both by day and by night. It therefore flies at an altitude of around 21km (70,000 feet) during daylight hours, and then glides slowly down to around 15km when the sun is unavailable to keep it aloft….

The main uses for satellites are observation and communication. Both are appealing markets for HAPS. Hovering drones could act as relays for telephone calls and internet traffic in places that do not have good enough infrastructure on the ground. And there is never a shortage of customers who would like to snoop on various parts of the Earth’s surface, whether for commercial or military reasons.

By satellite, such snooping is done from an altitude of about 800km. Zephyr flies at one-fortieth of that, so the optics its needs to take pictures are far less demanding. (Just as well, of course, for it is unlikely to be able to carry a huge payload.)

Airbus is not alone in the HAPS game. Google and Facebook are involved as well—and with similar customers in mind—though Google will also be its own customer, since keeping its Google Earth imagery up to date is a demanding task. Paul Brooks, spokesman for Airbus’s HAPS programme, says he does not see these firms as competitors, but rather as collaborators in proving the idea of endurance flight and promoting the changes in regulations needed to permit its safe use. Once this has happened, and the world’s aviation authorities have agreed common operating standards, HAPS should prove a cheap and reliable alternative to blasting things into orbit.

China’s Anti-Satellite Capabilities

Chinese media claimed on May 3, 2014 without reference to specific sources…that China has destroyed the control chip of a Japanese spy satellite with a secret weapon.  The attack reportedly happened when the satellite was tracking a Chinese J-20 stealth fighter jet in northwestern China. The satellite is the third Japanese spy satellite launched from Kagoshima, Japan….Chinese media goes on to claim that US analysts believe that China used the electromagnetic pulse weapon Poacher One in the attack. That is China’s top secret military research and development project.

The PLA’s electromagnetic weapon Poacher One is able to transmit an electromagnetic pulse of several megawatt continuously for one minute to destroy all military and civil electronic information and communications systems operating within a few kilometres. It can also destroy an enemy’s internal chips.  The report claims further that US military previously revealed that the PLA had sent a satellite near a US spy satellite and blinded it with spray of coating on its camera. PLA has lots of means to attack and interfere with satellites. US military is concerned that neutralisation of US satellites by PLA’s space force will be its nightmare in war.  However, the development of anti-satellite technology does not stop there. It may be the basis for the technology to intercept an ICBM. That will be a much greater worry for the US military.

Nowhere to Hide: Panopticon Satellites

From the DARPA website: DARPA’s Membrane Optical Imager for Real-Time Exploitation (MOIRE) program aims to create technologies that would enable future high-resolution orbital telescopes to provide real-time video and images of the Earth from Geosynchronous Earth Orbit (GEO)—roughly 22,000 miles above the planet’s surface. Size and cost constraints have so far prevented placing large-scale imaging satellites in GEO, so MOIRE is developing technologies that would make orbital telescopes much lighter, more transportable and more cost-effective.

Currently in its second and final phase, the program recently successfully demonstrated a ground-based prototype that incorporated several critical technologies, including new lightweight polymer membrane optics to replace glass mirrors. Membrane optics traditionally have been too inefficient to use in telescope optics. MOIRE has achieved a technological first for membrane optics by nearly doubling their efficiency, from 30 percent to 55 percent. The improved efficiency enabled MOIRE to take the first images ever with membrane optics.

While the membrane is less efficient than glass, which is nearly 90 percent efficient, its much lighter weight enables creating larger lenses that more than make up the difference. The membrane is also substantially lighter than glass. Based on the performance of the prototype, a new system incorporating MOIRE optics would come in at roughly one-seventh the weight of a traditional system of the same resolution and mass. As a proof of concept, the MOIRE prototype validates membrane optics as a viable technology for orbital telescopes.

“Membrane optics could enable us to fit much larger, higher-resolution telescopes in smaller and lighter packages,” said Lt. Col. Larry Gunn, DARPA program manager. “In that respect, we’re ‘breaking the glass ceiling’ that traditional materials impose on optics design. We’re hoping our research could also help greatly reduce overall costs and enable more timely deployment using smaller, less expensive launch vehicles.”

Instead of reflecting light with mirrors or refracting it with lenses, MOIRE’s membrane optics diffract light. Roughly the thickness of household plastic wrap, each membrane serves as a Fresnel lens—it is etched with circular concentric grooves like microscopically thin tree rings, with the grooves hundreds of microns across at the center down to only 4 microns at the outside edge. The diffractive pattern focuses light on a sensor that the satellite translates into an image.

MOIRE technology houses the membranes in thin metal “petals” that would launch in a tightly packed configuration roughly 20 feet in diameter. Upon reaching its destination orbit, a satellite would then unfold the petals to create the full-size multi-lens optics. The envisioned diameter of 20 meters (about 68 feet) would be the largest telescope optics ever made and dwarf the glass mirrors contained in the world’s most famous telescopes.

From GEO, it is believed, a satellite using MOIRE optics could see approximately 40 percent of the earth’s surface at once. The satellite would be able to focus on a 10 km-by-10 km area at 1-meter resolution, and provide real-time video at 1 frame per second.

Ball Aerospace & Technologies Corp. is the prime contractor for the MOIRE program.
