New Fait Accompli in Space: the Artemis Accords

Seven countries have joined the United States in signing the Artemis Accords on October 13, 2020, a set of principles governing norms of behavior for those who want to participate in the Artemis lunar exploration program: Australia, Canada, Japan, Luxembourg, Italy, the United Arab Emirates and the United Kingdom….The accords outline a series of principles that countries participating in the Artemis program are expected to adhere to, from interoperability and release of scientific data to use of space resources and preserving space heritage. Many of the principles stem directly from the Outer Space Treaty and related treaties.

NASA was originally focused on having the document apply to lunar and later Martian exploration. Japan wanted to include asteroid and comet missions as well, based on that country’s program of robotic asteroid missions like the Hayabusa2 asteroids sample return spacecraft. The document now includes asteroid and comet missions, as well as activities in orbit around the moon and Mars and the Lagrange points of the Earth-moon system.

NASA is implementing the Artemis Accords as a series of bilateral agreements between the United States and other countries, which allows them to move more quickly than if NASA sought a multilateral agreement under the aegis of the United Nations…Frans von der Dunk, a professor of space law at the University of Nebraska, drew parallels with development of international civil aviation regulations, which started with bilateral agreements between the United States and United Kingdom that were later copied among other nations. “That is something that will possibly happen here as well,” he said.

The bilateral nature of the accords, though, do present restrictions. China, for instance, cannot sign on, because NASA, under the so-called “Wolf Amendment” in US law, is restricted from bilateral cooperation with China.

The accords are outside the traditional UN framework of international space law – such as the UN Committee on the Peaceful Uses of Outer Space. The requirement to sign bilateral agreements with the US can be viewed as a way of trying to impose US preferences on how to regulate space on others. Russia has already stated that the Artemis Program is too “US-centric”.  India, Germany, France and the European Space Agency (ESA) have not yet signed on to the accords.

Government Intervention is Great: What China is Learning from the United States

A study published by the China Aerospace Studies Institute in September 2020′China’s Space Narrative: Examining the Portrayal of the US-China Space Relationship in Chinese Sources‘ used publicly available Chinese language resources to draw insights on how the Chinese view the U.S.-China space relationship. According to the study:

“Chinese sources weave a space narrative that portrays China as a modernizing nation
committed to the peaceful uses of space and serving the broader interests of advancing humankind through international space cooperation, economic development, and scientific discovery. Chinese sources minimize the military role of China’s space program.

In contrast, the same sources portray the United States as the leading
space power bent on dominating space, restricting access to space, and limiting international space cooperation to countries with similar political systems and level of economic development.

The report concludes that the United States and China are in a long-term competition in space in which China is attempting to become a global power, in part, through the use of space. China’s primary motivation for developing space technologies is national security…China’s space program is one element of its efforts to transition the current U.S.-dominated international system to a multipolar world….

Many Chinese writings on commercial space analyze the experiences of U.S. companies, with a particular focus on SpaceX. Chinese space experts call SpaceX the “major representative company” for commercial space worldwide. A report from Hong Kong media claims that Chinese investors view SpaceX as the “benchmark company” for emerging commercial space companies in the mainland. Chinese authors also follow developments in other U.S. commercial space companies, such as Digital Globe
and Rocket Lab.

Chinese authors also pay attention to the ways in which the U.S. government uses various policies and incentives to create a favorable ecosystem for the growth of new commercial space companies. Chinese writings analyze ways in which NASA has supported private companies with funding, technology transfer, consulting, and infrastructure leasing. Although their specific recommendations vary, Chinese authors view strong government oversight and intervention as crucial toward the success of the domestic commercial space industry.”

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.

Conquering Space: China’s X-37B and the United States

Ever since China claimed success in the secretive launch of an experimental spacecraft, experts have been pondering over what it could be and what it did in space.The spacecraft – mounted on a Long March 2F rocket – was launched from the Jiuquan Satellite Launch Centre in northern China on Sept. 4, 2020 and safely returned to Earth after two days in orbit…Unlike recent Chinese high-profile space missions, very few details have emerged about the vehicle and no visuals have been released. Chinese authorities have been tight-lipped about the nature of the short-duration excursion and what technologies were tested. The exact launch and landing times were not revealed, nor was the landing site although it is thought to be the Taklamakan Desert, which is in northwest China.

Three years ago, China said it would launch a space vessel in 2020 that “will fly into the sky like an aircraft” and be reusable. A reusable spacecraft – as the name implies can undertake multiple trips to space – thereby potentially lowering the overall cost of launch activity. A traditional one-off spacecraft – costing tens of millions of dollars – is practically rendered useless after a single mission.

The experimental vessel reached an altitude of about 350km, which is in line with China’s previous crewed flights. The spacecraft also released an unknown object into the orbit before returning to Earth…Once the testing is complete, such a vehicle could be used to launch and repair satellites, survey the Earth, as well as take astronauts and goods to and from orbit, possibly to a planned future Chinese space station.

The Chinese craft’s size and shape remain unclear but it is widely believed to be some sort of uncrewed space plane similar to the X-37B Orbital Test Vehicle operated by the US Air Force. The recent mission could be linked to the Shenlong – or divine dragon – space plane project, which has been in development for some time, according to reports. A second Chinese reusable space plane called Tengyun, or cloud climber, is also in the works. If confirmed as a space plane, China would become only the third country to have successfully launched such a vehicle into orbit after the US and the former Soviet Union. The European Space Agency is working on its own reusable orbital vehicle called Space Rider, while India is also said to be developing a space shuttle-like craft.

The X-37B, resembling a miniature space shuttle, has been in orbit since late May 2020 following its launch on its sixth assignment. Very little is known about the X-37B’s missions, prompting speculation that the planes could be used for spying activity or testing space weapons.

According to Bleddyn Bowen, China’s spacecraft launch is “just another part of China becoming a comprehensive space power that utilizes space technology for the purposes of war, development, and prestige like all others”.

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.”

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.”

The X-37B Drone: 4th Mission

The unmanned X-37B spacecraft was launched May 20 2015  atop a United Launch Alliance Atlas 5 rocket from Florida’s Cape Canaveral Air Force Station. The liftoff will begin the reusable space plane’s fourth mission, which is known as OTV-4 (short for Orbital Test Vehicle-4).  Most of the X-37B’s payloads and specific activities are classified, so it’s not clear what the space plane will be doing once it leaves Earth. This secrecy has led to some speculation that the vehicle might be some sort of space weapon. Air Force officials have repeatedly rejected that notion, saying that the X-37B flights simply test a variety of new space technologies.

For example, the space plane is carrying a type of ion engine called a Hall thruster on OTV-4, Air Force officials said. This Hall thruster is an advanced version of the one that powered the first three Advanced Extremely High Frequency military communications satellites, the officials added.  NASA is also flying an experiment on OTV-4. The agency’s Materials Exposure and Technology Innovation in Space investigation will see how exposure to the space environment affects nearly 100 different types of materials. The results should aid in the design of future spacecraft, NASA says.

The X-37B looks like a miniature version of NASA’s now-retired space shuttle. The robotic, solar-powered space plane is about 29 feet long by 9.5 feet tall (8.8 by 2.9 meters), with a wingspan of 15 feet (4.6 meters) and a payload bay the size of a pickup-truck bed. Like the space shuttle, the X-37B launches vertically and lands horizontally, on a runway.

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.

Just Hit See-Me: the new military satellites

The Seeme Program from DARPA website:

DARPA’s SeeMe (Space Enabled Effects for Military Engagements) program aims to give mobile individual US warfighters access to on-demand, space-based tactical information in remote and beyond- line-of-sight conditions. If successful, SeeMe will provide small squads and individual teams the ability to receive timely imagery of their specific overseas location directly from a small satellite with the press of a button — something that’s currently not possible from military or commercial satellites.

The program seeks to develop a constellation of small “disposable” satellites, at a fraction of the cost of airborne systems, enabling deployed warfighters overseas to hit ‘see me’ on existing handheld devices to receive a satellite image of their precise location within 90 minutes. DARPA plans SeeMe to be an adjunct to unmanned aerial vehicle (UAV) technology, which provides local and regional very-high resolution coverage but cannot cover extended areas without frequent refueling. SeeMe aims to support warfighters in multiple deployed overseas locations simultaneously with no logistics or maintenance costs beyond the warfighters’ handheld devices.

The SeeMe constellation may consist of some two-dozen satellites, each lasting 60-90 days in a very low-earth orbit before de-orbiting and completely burning up, leaving no space debris and causing no re-entry hazard. The program may leverage DARPA’s Airborne Launch Assist Space Access (ALASA) program, which is developing an aircraft-based satellite launch platform for payloads on the order of 100 lbs. ALASA seeks to provide low-cost, rapid launch of small satellites into any required orbit, a capability not possible today from fixed ground launch sites.

Raytheon Company was awarded a $1.5 million Defense Advanced Research Projects Agency (DARPA) contract for phase one of the agency’s Space Enabled Effects for Military Engagements (SeeMe) program. During the next nine months, the company will complete the design for small satellites to enhance warfighter situational awareness in the battlespace.  Raython News Release, Dec. 13, 2012
