DECODING: Shenlong releases a mystery object in orbit — China secretly militarizes space

The signal detected by LeoLabs

In June 2026, American company LeoLabs, which specializes in orbital traffic surveillance, detected an anomaly: the Shenlong — China's military spaceplane on a classified mission for several months — had just released a new object in low Earth orbit. The information was immediately relayed by Aviation Week on June 22, 2026. No official explanation came from Beijing. As always with the Shenlong, silence is the chosen form of communication.

This is not the first time the Shenlong has surprised observers. The vehicle, China's counterpart to the American X-37B, is designed for long-duration missions in low Earth orbit — months, sometimes more than a year. During that time, it maneuvers, tests systems, and, manifestly, releases objects whose nature remains unknown. The fact that LeoLabs is capable of detecting these events is itself a step forward in civilian space surveillance — but that surveillance is not enough to reveal intent.

The American X-37B lands after 908 days

The context is particularly striking: in June 2026, the American X-37B was landing after 908 consecutive days in orbit, according to Ronin's Grips' report of June 20, 2026. The two spaceplanes were therefore crossing paths in low Earth orbit at the very moment the Shenlong was conducting its release maneuver. Coincidence or deliberate demonstration of capability in the face of an American competitor completing its mission? The answer is probably the second.

This orbital parallelism between the two military space powers perfectly illustrates the new reality: space has once again become a domain of intense strategic competition, with actors who monitor each other and test their respective capabilities knowing full well that they are being watched. Transparency itself becomes a strategic tool — or its absence, a declaration of intent.

The Shenlong releasing a mystery object while the American X-37B heads home — this timing owes nothing to chance. Beijing has a well-oiled habit of scheduling its capability demonstrations at the most visible moment. It is strategic communication, but in orbit.

A next-generation spaceplane

The Shenlong ("Celestial Dragon") is the most secretive program of the Chinese Air Force in the space domain. Visually similar to the American X-37B, it is of slightly different dimensions and has demonstrated advanced orbital maneuvering capabilities during its previous missions. It is launched by Chinese rockets, lands autonomously, and its exact payload remains classified.

What makes the Shenlong particularly concerning is its potential versatility. The orbital rendezvous and satellite servicing technologies it tests — legitimate capabilities in theory — can be directly adapted to anti-satellite operations: approach, neutralization, or even capture of adversary satellites. Dual-use technology is Beijing's preferred strategic tool precisely because it blurs the lines between civilian and military applications.

The released object: expert hypotheses

What could this object released by the Shenlong be? Space security experts propose several hypotheses, all legitimately concerning. It could be a surveillance micro-satellite designed to spy on adversary space assets at close range. It could be an ASAT technology demonstrator — an object capable of approaching, disrupting, or neutralizing an enemy satellite. It could also be an orbital electronic warfare system, designed to jam communications or GPS signals over a specific geographic area.

None of these hypotheses is reassuring, and China provides no information to rule them out. In the military space domain, the absence of explanation is itself a threat — it forces adversaries to plan for the worst-case scenario, consuming intelligence, countermeasure, and planning resources without a single yuan being spent by Beijing.

Strategic ambiguity is cheap to produce and expensive for the adversary to manage. Beijing has understood this better than anyone. Every mystery object released by the Shenlong forces U.S. Space Command into analyses, simulations, and countermeasures that cost millions. Brilliant. And alarming.

Four satellites against one: Operation Kosmos

While China operates in secrecy, Russia takes a more direct and more alarming approach. According to RBC-Ukraine of June 24, 2026, four Russian Kosmos satellites (2610, 2611, 2612, 2613) approached within 13 kilometers of the satellite ICEYE-X36 — a Finnish synthetic aperture radar satellite actively used by Ukraine to monitor Russian troop movements. The incident occurred at 550 kilometers altitude in low Earth orbit.

Thirteen kilometers in orbit is an infinitesimal distance at these speeds — several kilometers per second. The Kosmos satellites were clearly maneuvering in a coordinated fashion to encircle and surveil ICEYE-X36, and potentially to disrupt it. This is a flagrant demonstration of operational ASAT capability, executed in real time during an armed conflict, against a satellite that directly provides intelligence to an army at war.

ICEYE-X36: a crucial asset for Ukrainian defense

ICEYE-X36 is one of Ukraine's most valuable space assets. The synthetic aperture radar (SAR) satellite can image the Earth's surface at night and by day, in all weather conditions, with resolution sufficient to detect military vehicles, artillery positions, and troop movements. These capabilities are directly integrated into Ukrainian operational planning.

Finland, a NATO member since 2023, has provided or facilitated access to these satellite capabilities for Ukraine. The approach of the Russian Kosmos satellites to within 13 km of ICEYE-X36 is therefore a demonstration explicitly directed at NATO as much as at Kyiv: we can neutralize your eyes in space if we choose to. This is an existential threat to Ukrainian informational superiority.

Four Russian satellites encircling a Finnish satellite used by Ukraine — that is an act of war in space, without a declaration of war. If ICEYE-X36 is neutralized, Ukrainian soldiers will die on the ground because they will have lost critical information. Space warfare is no longer science fiction. It is happening now.

The 2021 Nudol ASAT: the textbook case

To understand what Russia is capable of, one must recall the precedent of November 2021: the Russian military tested its Nudol ASAT missile by deliberately destroying an old Soviet satellite, Kosmos-1408, in low Earth orbit. The explosion created a cloud of more than 1,500 trackable debris pieces and potentially hundreds of thousands of smaller fragments, forcing the crew of the International Space Station to shelter for several hours.

This irresponsible act provoked near-unanimous international condemnation — but no concrete consequences for Moscow. Worse, it demonstrated a real capability: Russia can destroy satellites in low Earth orbit, creating debris that threatens the entire orbital domain for decades. This is a weapon of orbital mass destruction, and its use would be catastrophic for all of humanity.

Debris and international law: a gaping void

International space law is catastrophically behind the technological and strategic reality. The Outer Space Treaty of 1967 — the fundamental legal framework — did not envision the multiplication of actors, commercial satellite constellations, or sophisticated ASAT systems. The deliberate creation of orbital debris in wartime is a legal gray zone exploited by Russia and, potentially, by China.

The Express UK of June 25, 2026 reports that Russia is also developing a nuclear-powered space weapon — a system that, if deployed, would be capable of generating an orbital electromagnetic pulse (EMP) neutralizing entire satellite constellations. This threat, partially confirmed by American intelligence sources, represents the ultimate space deterrence weapon.

An orbital nuclear EMP would erase our GPS, our satellite communications, our military navigation systems. All of modern warfare depends on satellites. Russia knows this. And it says so. This is the kind of threat that cannot be ignored and cannot easily be countered. Space has become the Achilles' heel of our technological societies.

United States, China, Russia: three space doctrines

The three major military space powers are developing distinct approaches. The United States, with U.S. Space Command created in 2019, bets on constellation resilience — multiplying satellites so that no attack can neutralize all of them — and on defensive orbital rendezvous capabilities. The X-37B is the spearhead of this strategy.

China combines development of direct ASAT, ambiguous orbital maneuvers via the Shenlong, and multiplication of its own GPS (Beidou) and surveillance constellations. Russia, whose space industrial base has degraded since 2022 under the effect of sanctions, increasingly bets on low-cost demonstrations of force — frightening with the Kosmos, threatening to use the Nudol — rather than on costly systemic modernization.

European and Ukrainian vulnerability

In this context, the vulnerability of European countries and Ukraine is glaring. Europe has no equivalent to the X-37B, no ASAT capability, and depends massively on American constellations for its secure military communications. Ukraine benefits from Starlink, ICEYE, and a few other commercial capabilities — but their survival in the event of spatial escalation would be precarious.

The E5 declaration of June 24, 2026 identifies space as a collective defense priority, but investments remain insufficient in the short term. Building European space resilience will take years and tens of billions of euros. In the meantime, Finnish satellites operate at 550 km altitude, surrounded by unfriendly Russian neighbors.

Europe has been talking about strategic autonomy for ten years, but still has no spaceplane, no ASAT capability, no autonomous orbital surveillance capability. Meanwhile, China releases mystery objects and Russia sends four satellites to harass ICEYE-X36. The urgency is not in the speeches — it is in the budgets and the timetables.

The spatial dimension of the Ukrainian conflict

The war in Ukraine is the first large-scale conflict in the commercial space era. Both parties are using commercial satellites — for surveillance, communications, navigation — at unprecedented historical intensity. Starlink literally saved Ukrainian command capability during the breakdown of classical communications. ICEYE provides radar imagery that even some Western intelligence services envied ten years ago.

The threat of Russian Kosmos satellites against ICEYE-X36 is therefore not an abstract demonstration — it is a direct attempt to weaken Ukraine's operational capability at the front. Every hour during which ICEYE-X36 is disrupted or taken offline is a window of opportunity for Russian maneuvers that Ukraine will not see coming. Space is the third dimension of the Ukrainian front, as real as the ground and the air.

NATO's response: guaranteeing orbital security

NATO declared space its fifth operational domain in 2019, but concrete mechanisms for collective space defense remain embryonic. If a member country's satellite is deliberately neutralized by Russia or China, what is space's Article 5? This question remains without a precise answer, which creates a dangerous gray zone that Moscow and Beijing exploit with meticulous care.

The NATO summit in Ankara on July 7-8, 2026 will be a crucial opportunity to clarify this doctrine. The "tens of billions" in defense contracts announced by Rutte must explicitly include investments in space resilience — replacement satellites, orbital surveillance capabilities, and, as a last resort, credible countermeasures against adversary ASATs.

Article 5 in space — that question haunts me. If an American satellite is neutralized by a Russian Kosmos, is that an act of war? Do Europeans have to respond? Nobody really knows. And that uncertainty is itself an invitation to escalation.

When the private sector monitors better than states

LeoLabs is a California-based private company operating a global network of ground-based radars dedicated to low Earth orbit surveillance. Its ability to detect the object released by the Shenlong illustrates an important structural phenomenon: in certain space surveillance domains, the commercial private sector is now as capable as state intelligence services, with the advantage of making its data public.

This democratization of space surveillance is a double-edged sword. It allows small nations, research organizations, and journalists to document military orbital activities that great powers would prefer to keep secret. But it also creates pressure on those same great powers to develop even stealthier systems — fueling yet another technological spiral.

The orbital information war

LeoLabs' detection and Aviation Week's publication of the Shenlong maneuver creates a media fait accompli: China knows it has been seen, the world knows China has been seen. In this context, transparency compelled by civilian surveillance plays a partial deterrence role. A state that knows its maneuvers will be detected and published within 48 hours must calculate the reputational costs of its actions.

This mechanism is fragile — China will continue its Shenlong maneuvers regardless of LeoLabs publications — but it constitutes an emerging form of popular oversight of military space activities, complementary to official diplomatic mechanisms that, for their part, advance at the speed of multilateral negotiations.

LeoLabs accomplishes in a few hours what diplomats fail to do in a few years: making the military invisible visible. I find in this fact a form of hope. The surveillance technology that states use against their citizens can be turned — by other technological actors — against the secret military activities of states. Forced transparency as a counterweight to space militarization.

The orbital escalation scenario

Experts from Defense Express, cited by UA News on June 20, 2026, assessed Russia's actual capabilities in space threats against Ukraine. Their conclusion is nuanced: Russia has advanced orbital electronic jamming and hostile surveillance capabilities, but a physical destruction of ICEYE-X36 via a Nudol or a powered Kosmos remains politically risky because of the debris generated.

The most likely short-term scenario is therefore an orbital war of attrition: harassment of adversary satellites, intermittent jamming, intimidating approaches, without direct physical destruction. This mode of operation avoids open escalation while degrading adversary capabilities — hybrid warfare applied to space.

Preventing catastrophe: diplomatic initiatives

Faced with these risks, several diplomatic initiatives are attempting to build behavioral norms for military space. The United Nations has engaged discussions on the prevention of an arms race in space, but with few concrete results in the face of Russian veto power and China's dilatory attitude. The European Union is seeking to establish a code of conduct for space activities, an initiative that remains fragile without the adherence of the two principal threatening powers.

The reality is that the militarization of space is underway, that diplomatic safeguards are insufficient, and that democracies must simultaneously strengthen their space defenses while pushing for common rules of engagement. This is not a contradiction — it is the very definition of responsible deterrence.

I must admit a limitation: I do not know exactly what Beijing intends to do with the object released by the Shenlong. Nobody really does. And that is precisely the problem with strategic ambiguity — it forces one to plan for the worst, spend for the worst, stress over the worst. Uncertainty itself is a weapon.

The mystery object: what its discovery reveals about our surveillance

Progress in the science of orbital surveillance

LeoLabs' ability to detect an object released by the Shenlong in low Earth orbit testifies to the spectacular progress of space domain awareness. Networks of increasingly sensitive ground-based radars, combined with advanced data processing algorithms, now make it possible to track objects of a few tens of centimeters at hundreds of kilometers altitude.

This evolution is vital for global space security. The multiplication of debris, nano-satellites, and discreet military systems makes orbital traffic management increasingly critical. Ultimately, an unintentional collision between objects in low Earth orbit could trigger a Kessler effect — a cascade of debris that would render certain orbits unusable for decades, with catastrophic consequences for our communications, navigation, and meteorological surveillance capabilities.

A call for international transparency

The structural solution requires greater international transparency on military orbital activities. The United States, which publishes the catalog of its own launches, could exert strong diplomatic pressure for China and Russia to do the same — or be compelled by international resolutions. The European Space Agency (ESA) could play a mediating role by proposing notification standards that military powers would have an interest in adopting to avoid accidents.

Space cannot durably remain an unregulated domain of military competition. The consequences — for civilian communications, navigation, meteorological warning systems — affect all of humanity, not just military forces. What happens in orbit concerns every human being who owns a smartphone, uses GPS, or checks a satellite weather forecast.

The next time you check your GPS or consult a satellite map, think about it: that functionality depends on satellites operating at 550 km altitude, potentially surrounded by Russian Kosmos and Chinese mystery objects. Our technological daily life rests on a space infrastructure that is becoming a little more militarized, a little more threatened, every day. This is not a geopolitical abstraction — it is your daily reality.

What the absence of communication reveals

The fact that China provided no explanation for the object released by the Shenlong is not negligence — it is a deliberate policy. Beijing maximizes strategic uncertainty by letting its adversaries imagine the worst. This approach is inexpensive for China and very costly for its adversaries, who must mobilize intelligence, countermeasure, and planning resources for all eventualities.

The West cannot manage this uncertainty by ignoring it. It must invest in its orbital surveillance capabilities, strengthen cooperation among allies on space intelligence sharing, and develop credible countermeasures against hostile maneuvers in orbit — without triggering an uncontrolled escalation spiral.

Space as a new front in systemic competition

The Shenlong, ICEYE-X36, and the Kosmos satellites are not isolated incidents — they are manifestations of a systemic confrontation between democracies and autocracies that now extends into orbit. Russia threatens the satellites that help Ukraine survive. China is developing capabilities that will challenge American space supremacy. The defense of democracies now passes through the defense of their orbital assets.

The next major war will not be fought only in the trenches or in the air — it will be fought in part at 550 km altitude, between objects that most citizens will never see but whose neutralization would decide the outcome of ground battles. Space is the new center of gravity of international security, and it is time that Western leaders treated it as such.
