Elon Musk’s internet satellite venture has spawned an unlikely alliance of competitors, regulators and experts who say the billionaire is building a near-monopoly that is threatening space safety and the environment. The Starlink project, owned by Mr. Musk’s Space Exploration Technologies Corp. or SpaceX, is authorized to send some 12,000 satellites into orbit to beam superfast internet to every corner of the Earth. It has sought permission for another 30,000.
Now, rival companies such as Viasat, OneWeb, Hughes Network Systems and Boeing Co. are challenging Starlink’s space race in front of regulators in the U.S. and Europe. Some complain that Mr. Musk’s satellites are blocking their own devices’ signals and have physically endangered their fleets. Mr. Musk’s endeavor is still in beta testing but it has already disrupted the industry, and even spurred the European Union to develop a rival space-based internet project to be unveiled by the end of the year.
The critics’ main argument is that Mr. Musk’s launch-first, upgrade-later principle, which made his Tesla Inc. TSLA electric car company a pioneer, gives priority to speed over quality, filling Earth’s already crowded orbit with satellites that may need fixing after they launch.
“SpaceX has a gung-ho approach to space,” said Chris McLaughlin, government affairs chief for rival OneWeb. “Every one of our satellites is like a Ford Focus—it does the same thing, it gets tested, it works—while Starlink satellites are like Teslas: They launch them and then they have to upgrade and fix them, or even replace them altogether,” Mr. McLaughlin said. Around 5% of the first batch of Starlink satellites failed, SpaceX said in 2019….
Orbital space is finite, and the current lack of universal regulation means companies can place satellites on a first-come, first-served basis. And Mr. Musk is on track to stake a claim for most of the free orbital real estate, largely because, unlike competitors, he owns his own rockets.

The joint announcement by China and Russia in March 20211 on their collaboration to explore the moon has the potential to scramble the geopolitics of space exploration, once again setting up competing programs and goals for the scientific and, potentially, commercial exploitation of the moon. This time, though, the main players will be the United States and China, with Russia as a supporting player.
In recent years, China has made huge advances in space exploration, putting its own astronauts in orbit and sending probes to the moon and to Mars. It has effectively drafted Russia as a partner in missions that it has already planned, outpacing a Russian program that has stalled in recent years. In December 2020, China’s Chang’e-5 mission brought back samples from the moon’s surface, which have gone on display with great fanfare in Beijing. That made China only the third nation, after the United States and the Soviet Union, to accomplish the feat. In the coming months, it is expected to send a lander and rover to the Martian surface, hard on the heels of NASA’s Perseverance, which arrived there in February 2021..
According to a statement by the China National Space Administration, they agreed to “use their accumulated experience in space science research and development and use of space equipment and space technology to jointly formulate a route map for the construction of an international lunar scientific research station.”
After the Soviet Union’s collapse, Russia became an important partner in the development of the International Space Station. With NASA having retired the space shuttle in 2011, Russia’s Soyuz rockets were the only way to get to the International Space Station until SpaceX, a private company founded by the billionaire Elon Musk, sent astronauts into orbit on its own rocket last year. China, by contrast, was never invited to the International Space Station, as American law prohibits NASA from cooperating with Beijing.
China pledged to keep the joint project with Russia “open to all interested countries and international partners,” as the statement put it, but it seemed all but certain to exclude the United States and its allies in space exploration. The United States has its own plans to revisit the moon by 2024 through an international program called Artemis. With Russia by its side, China could now draw in other countries across Asia, Africa and Latin America, establishing parallel programs for lunar development….
Excerpts from China and Russia Agree to Explore the Moon Together, NYT, Mar. 10, 2021
U.S. government and aerospace-industry officials are removing decades-old barriers between civilian and military space projects, in response to escalating foreign threats beyond the atmosphere. The Pentagon and the National Aeronautics and Space Administration (NASA) are joining forces to tackle efforts such as exploring the region around the moon and extending the life of satellites. Many details are still developing or remain classified. Driving the changes are actions by Moscow and Beijing to challenge American space interests with antisatellite weapons, jamming capabilities and other potentially hostile technology. Eventually, according to government and industry officials briefed on the matter, civil-military cooperation is expected to extend to defending planned NASA bases on the lunar surface, as well as protecting U.S. commercial operations envisioned to extract water or minerals there…
Large and small contractors are maneuvering to take advantage of opportunities to merge military and nonmilitary technologies. They include established military suppliers that already have a foot in both camps, such as Northrop Grumman, the Dynetics unit of Leidos Holdings, and Elon Musk’s Space Exploration Technologies Corp. Smaller companies such as Maxar Technologies Holdings, closely held robotic-lander maker Astrobotic Technology, and small-satellite producer Blue Canyon Technologies, recently acquired by Raytheon Technologies, also seek to diversify in the same way…
The U.S. astronaut corps always has included many military officers, some previous NASA scientists quietly shared data with military counterparts and NASA’s now-retired Space Shuttle fleet was supposed to launch Pentagon satellites. But today, veteran industry and government experts describe the cooperation as much more extensive, covering burgeoning capabilities such as repairing and repurposing satellites in orbit, or moving them around with nuclear propulsion. Intelligence agencies are more involved than ever in leveraging civilian technology, including artificial intelligence, robotic capabilities and production know-how.
Excerpt from Pentagon, NASA Knock Down Barriers Impeding Joint Space Projects, WSJ, Feb. 1, 2021
The part of space nearest Earth, known technically as low-Earth orbit, is getting cluttered. Some of the objects up there are working satellites. Some are satellites that have stopped working. Some are stages of the rockets which put those satellites into orbit. And a lot are debris left over from explosions and collisions between larger objects.
The risk of such collisions is increasing, for two reasons. First, the number of satellites being launched is rising. Second, collisions themselves beget collisions. The fragments they create add to the number of orbiting objects. At the moment, more than 20,000 such objects are being tracked, but there may be as many as 1million bigger than 1cm across. In the long term, this accumulation of junk may lead to a chain reaction, known as Kessler syndrome, that would make some low-Earth orbits unusable. Even in the short term it puts lots of expensive hardware at risk. So plans are being laid to send up special craft to “deorbit” redundant satellites and rocket stages. Given the current situation, this is a good, if expensive, idea. But a better one for the future would be to build deorbiting into the life-cycles of satellites and rocket stages from the beginning.
There are several ways of doing this. One is a “launch tax”. But that would load costs onto the satellite industry…A second idea is a space-going “bottle deposit” scheme. Satellite owners would pay an agreed sum into an escrow account that was redeemable when they deorbited their property. If they did not do so, enterprising salvagers could try to do it for them, and claim the deposit if successful. This has the virtue of encouraging built-in deorbiting capability….
The best idea, though, is to attack the problem at its roots. The littering of space is an example of the “tragedy of the commons”, in which no charge is made for the use of a resource that is owned collectively. So why not charge the beneficiaries for the right to put something into orbit and keep it there? The longer an object stays up, the more the satellite owner pays. The more popular (and hence crowded) the orbit chosen, the more expensive it would be to add a satellite to it.
That raises the question of who would do the charging. The Outer Space Treaty, signed in 1967, assigns responsibility and liability for objects in orbit to the country which launches them, and entreats signatories to avoid harmful contamination of space and celestial bodies. It would make sense for countries with space-launch capability, and thus an interest in keeping space clean, to hammer out a new and specific agreement. A well-crafted treaty would clean up space, cause it to be used more efficiently, and raise some useful revenue from a resource currently exploited for nothing.
To deal with non-participants acting as free-riders, participants might agree to make pariahs of firms that tried to take advantage in this way… Other natural commons, notably the oceans and the atmosphere, have suffered, and still suffer, from a lack of sensible arrangements for their joint exploitation. It is not too late to stop outer space being added to that list.

The US President issued Space Policy Directive-6 (SPD-6), the Nation’s Strategy for Space Nuclear Power and Propulsion (SNPP) on Dec. 16, 2020. Space nuclear systems power spacecraft for missions where alternative power sources are inadequate, such as environments that are too dark for solar power or too far away to carry sufficient quantities of chemical fuels. Space nuclear systems include radioisotope power systems and nuclear reactors used for power, heating, or propulsion. SPD-6 establishes high-level goals, principles, and a supporting roadmap that demonstrate the U.S. commitment to using SNPP systems safely, effectively, and responsibly…
NASA, the Department of Energy, and industry will design, fabricate, and test a 10-kilowatt class fission surface power system. NASA plans to demonstrate the system on the Moon in the late 2020s, providing power for sustainable lunar surface operations and testing its potential for use on Mars. The space agency is also advancing nuclear thermal and nuclear electric propulsion capabilities. Nuclear propulsion can enable robust human exploration beyond the Moon. For crewed missions to the Red Planet, a traditional chemical propulsion system would require a prohibitively high propellant mass.
NASA Supports America’s National Strategy for Space Nuclear Power and Propulsion, NASA Press Release, Dec. 16, 2020
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 wayof 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.
Excerpt from Jeff Foust ,Eight countries sign Artemis Accords, Space News, Oct. 13, 2020
“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.”
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 theShenlong – or divine dragon – space plane project, which has been in development for some time, according to reports. A second Chinese reusable space plane calledTengyun,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”.

Kosmos 2542, a Russian satellite that was launched in November 2019, was “like Russian nesting dolls”. Eleven days after its launch it disgorged another satellite, labelled Kosmos 2543. Then, on July 15th, Kosmos 2543 itself spat out another object, which sped off into the void. Merely a “small space vehicle” to inspect other satellites, said the Russians. Nonsense, said the Americans; it was a projectile. The intentl.. was to signal Russia’s ability to destroy other nations’ satellites….In January 2020, America complained that Kosmos 2542 and 2543 had tailed a spy satellite in an “unusual and disturbing” way (American satellites have also sidled up to others in the past).
Anti-satellite weapons are not new. During the cold war, America and the Soviet Union developed several ways to blow up, ram, dazzle and even nuke each other’s satellites. The countries conducted two-dozen anti-satellite tests between them. Ten were “kinetic”, involving a projectile physically striking a target. But new competitors, and new technologies, mean anti-satellite warfare is a hot topic once again. China has conducted ten tests over the past 15 years, including a kinetic one in 2007 that created a great deal of space debris. India conducted its first kinetic test in 2019. America, Russia and China have all manoeuvred their satellites close to others, sometimes provocatively so. New methods of attack are being tested, including lasers and cyber-attacks.
Some satellites, such as America’s GPS constellation, blur the distinction between military and civilian assets. Over the past decade, America’s armed forces have put payloads on three commercial satellites, and plan to pay Japan to host others on its own navigation satellites….Then there is the question of what counts as an attack. Michael Schmitt, a law scholar, and Kieran Tinkler, a professor at the us Naval War College, say it is unclear whether jamming a civilian satellite would violate the general prohibition on attacking civilian objects. Blowing up a military one, meanwhile, might or might not constitute an indiscriminate (and hence illegal) attack, depending on whether it could have been disabled by other means and how much debris was produced.
Perhaps the biggest difference between space war and terrestrial war is how long the consequences can last. Much of the debris from China’s 2007 test, for instance, will still be in space at the turn of the next century. The more debris, the greater the likelihood of accidental collisions with other satellites, which generates more debris in turn. Enough debris could lead to a chain reaction known as Kessler syndrome, which could render entire swathes of near-Earth space unusable for decades…
The Outer Space Treaty of 1967 requires states to consult each other on actions that “would cause potentially harmful interference”, though the rule has rarely been heeded. Most countries accept that, in wartime, a body of existing laws known as international humanitarian law would apply, as on Earth—something America confirmed in its “Spacepower” doctrine, published on August 10, 2020. International humanitarian law is based on principles such as distinction (between combatants and civilians) and proportionality (between civilian harm and military advantage). But how to apply such ideas in a place with few humans is not always obvious.
Russia and China would like a formal treaty banning all weapons in space. Both are keen to prevent America from deploying space-based anti-missile systems which might threaten their own nuclear forces. America and its allies resist this. They argue that it is impossible to define a space weapon—anything that manoeuvres in orbit could serve as one—and that it would be easy to cheat. The European Union has instead proposed a voluntary code of conduct. Many non-Western countries would prefer a binding treaty…. Though most are not space powers, many are likely to become so in the future, so their buy-in is important.
Excerpts from Satellite warfare: An arms race is brewing in orbit, Economist, Aug. 15, 2020
The US government is starting to lay down the groundwork for diplomacy on the moon. On 15 May, 2020 NASA administrator Jim Bridenstine released a set of principles that will govern the Artemis Accords on the exploration of the moon. The accords are named after NASA’s Artemis programme, the US initiative to explore the moon, with a planned launch of astronauts to the lunar surface in 2024. Other countries are also increasingly turning towards the moon, which is concerning when a landing on the moon can send up clouds of potentially hazardous dust that travel a long way across the surface and even into orbit…
At the moment, there is little practical international law governing activities on the moon. TheOuter Space Treaty of 1967 deals with general space exploration, while the more specific Moon Agreement of 1984 states that “the moon and its natural resources are the common heritage of all mankind”, prohibiting the ownership of any part of the moon or any resources from the moon….However, no nation capable of human space flight has signed the Moon Agreement, effectively rendering it moot. In fact, in April 2020, US president Donald Trump issued an executive order supporting moon miningand taking advantage of the natural resources of space.
The Artemis Accords aim to protect historic locations like the Apollo landing sites but encourage mining in other areas. They also promote transparency and communication between nations, requiring signatories to share their lunar plans, register any spacecraft sent to or around the moon and release scientific data to the public. That transparency requirement might be a stumbling block for potential parties to the accords, says Forczyk. “I really don’t know how much countries are going to be willing to share some of their more delicate, sensitive information,” she says. “
The rest of the stipulations of the Artemis Accords are about safety: nations will be able to set “safety zones” to protect their activities on the moon, they will have to work to mitigate the effects of debris in orbit around the moon and they will agree to provide emergency assistance to any astronauts in distress.
Rather than attempting to put together an international treaty, which could be difficult to negotiate before NASA’s next crewed launch to the moon, the US will sign bilateral agreements with individual countries.
Excerpts from Leah Crane, NASA’s Artemis Accords aim to lay down the law of the land on the moon, New Scientist, May 20, 2020
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.”
Excerpts from Inigo Monzon , NATO Prepares For Space Warfare By Militarizing Low Earth Orbit, International Business Times, June 24, 2019
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.”
Excerpts from ALAN BOYD, Asia’s Space Race Gathers Pace, Asia Times, Jan. 6, 2018
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.
Excerpts from Christian Davenport: A fight to protect ‘the most valuable real estate in space, Washington Post, May 9, 2016
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.
