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.”

5,000 Eyes in the Sky: environmental monitoring

The most advanced satellite to ever launch from Africa will soon be patrolling South Africa’s coastal waters to crack down on oil spills and illegal dumping.  Data from another satellite, this one collecting images from the Texas portion of a sprawling oil and gas region known as the Permian Basin, recently delivered shocking news: Operators there are burning off nearly twice as much natural gas as they’ve been reporting to state officials.

With some 5,000 satellites now orbiting our planet on any given day…. They will help create a constantly innovating industry that will revolutionize environmental monitoring of our planet and hold polluters accountable…

A recent study by Environmental Defense Fund focused on natural gas flares from the wells in the Permian Basin, located in Western Texas and southeastern New Mexico. Our analysis proved that the region’s pollution problem was much larger than companies had revealed.  A second study about offshore gas flaring in the Gulf of Mexico, published by a group of scientists in the Geophysical Research Letters, showed that operators there burn off a whopping 40% of the natural gas they produce.

Soon a new satellite will be launching that is specifically designed not just to locate, but accurately measure methane emissions from human-made sources, starting with the global oil and gas industry.  MethaneSAT, a new EDF affiliate unveiled in 2018, will launch a future where sensors in space will find and measure pollution that today goes undetected. This compact orbital platform will map and quantify methane emissions from oil and gas operations almost anywhere on the planet at least weekly.

Satellites and Algorithms against Slaveholders

Brick kilns, tens of thousands across South Asia are often run on forced labor.  Satellite imagery of such kilns can help tally the kilns, enabling organizations on the ground to target slaveholders at the sites…

Some 40.3 million people are held in bondage today, according to the latest estimates from the International Labor Organization, headquartered in Geneva, Switzerland. But finding them is hard… Boyd who works for the Rights Lab estimates, however, that one-third of all slavery is visible from space, whether in the scars of kilns or illegal mines or the outlines of transient fish-processing camps.

Boyd is now using artificial intelligence to speed up the search. As a pilot project, she and her colleagues at the Rights Lab used crowdsourced visual searchers to identify brick kilns. The oval shape of the large ovens, sometimes 150 meters long, and their chimneys are distinctive, even from space. “You cannot mix them up with something else,” Boyd says.

Since then, Boyd has turned to machine-learning algorithms that recognize the kilns after being trained on the human-tagged examples. Last month, in the journal Remote Sensing, she and her colleagues reported that the algorithms could correctly identify 169 of 178 kilns in Google Earth data on one area of Rajasthan, although it also output nine false positives…

Another company, called Planet, has about 150 small satellites that snap images of the globe’s entire landmass daily. The images are lower-resolution than DigitalGlobe’s, but their frequency opens up opportunities to identify changes over time.With Planet data, Boyd and the Rights Lab plan to investigate fast moving signatures of slavery. From space, you can watch a  harvest in Turkmenistan and, based on how quickly the cotton disappears, you can tell whether machines or hands picked it. In the Sundarbans, an area spanning India and Bangladesh, shrimp farms and fish-processing camps employ slave labor to clear mangrove trees—a process satellites can capture.

The Space Rat Race

India, Japan and other space-faring countries are waking up to a harsh reality: Earth’s orbit is becoming a more dangerous place as the U.S., China and Russia compete for control of the final frontier…New Delhi is nervous because China has made no secret of its desire for influence in the Indian Ocean. China set up a naval base in Djibouti, a gateway to the ocean at the Horn of Africa. It secured a 99-year lease to the port of Hambantota in Sri Lanka. It is deeply involved in development projects in Maldives.

India has established itself as a player in the budget satellite business. It even put a probe into orbit around Mars in 2014, in a U.S.-assisted project that cost just $76 million. But it is scurrying to enhance its ability to monitor China’s activities, and the partnership with Japan is part of this.  Another sign that space is becoming a defense focus for India came on Dec. 19, when the country launched its third military communications satellite, the GSAT-7A. The satellite will connect with ground-based radar, bases and military aircraft, along with drone control networks.

China’s success in landing a craft on the far side of the moon on Jan. 3, 2019 came as a fresh reminder of its growing prowess. In late December, China also achieved global coverage with its BeiDou Navigation Satellite System. Only the U.S., Russia and the European Union had that capability.China aims to launch a Mars explorer in 2020 and complete its own Earth-orbiting space station around 2022.  In the back of Indian and Japanese officials’ minds is likely a stunning test China conducted in 2007. Beijing successfully destroyed one of its own weather satellites with a weapon, becoming only the third nation to pull off such a feat, after the Soviet Union and the U.S.

In December 2018, President Donald Trump ordered the Department of Defense to create a Space Command, widely seen as a precursor to a full-fledged Space Force.  There were 1,957 active satellites orbiting Earth as of Nov. 30, 2018 according to the Union of Concerned Scientists, a nonprofit U.S. advocacy group. America had the most by far, with 849, or 43% of the total. China was No. 2, with 284, followed by Russia with 152.  Japan and India had a combined 132 — 75 for the former and 57 for the latter.

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.
