A Russian satellite just took a very close look at an American spacecraft in low Earth orbit.

A few days ago, the snooping satellite Kosmos 2612 rendezvoused with ICEYE-X36, a commercial craft that observes our planet using synthetic aperture radar (SAR).

The close encounter, which occurred between Oct. 15 and Oct. 19, was reported by Marco Langbroek and other satellite trackers, with Langbroek calling it "a worrisome cat-and-mouse game" in orbit. The rendezvous has garnered a lot of attention in space circles, because it was non-consensual and startlingly close; at one point, the two spacecraft may have been separated by just a few meters. What did Russia hope to gain from it?

Not an isolated incident

Before tackling that question, we need to set the stage a bit. For example, it's important to note that inspections aren't unheard of in the final frontier. Russia, the United States and China have all maneuvered satellites into close proximity of other nations' hardware in recent years.

Most of this activity has taken place in geostationary orbit, which lies 22,236 miles (35,786 kilometers) above Earth. At this altitude, orbital velocity matches our planet's rotational speed, allowing spacecraft to "hover" over one patch of Earth continuously. GEO is therefore a popular destination for spy, communications and weather satellites — and for spacecraft designed to shadow and assess them.

Kosmos 2612 is operating in low Earth orbit (LEO), which is part of the reason its activities have created such a stir. Neither China nor the U.S. has conducted an uncooperative rendezvous in LEO, as far as we know. But Russia has, according to Victoria Samson, chief director of space security and stability for the nonprofit Secure World Foundation.

"They've done a few," she told Space.com. "Kosmos 2543 got within about 30 kilometers [19 miles] of USA 245 in January 2020, and then Kosmos 2558 got within about 70 kilometers [43 miles] of USA 326 in August 2022. And they've done repeated approaches to 326."

Kosmos 2612 got much closer to its target than those other inspectors did, of course. And there's another big difference: USA 245 and USA 326 are classified spy satellites managed by the U.S. National Reconnaissance Office, while ICEYE-X36 is a private Earth-observing craft.

Eyes in the sky

There are about 80 ICEYE spacecraft in LEO at the moment. They image our planet using SAR, which can peer through clouds and gather data both day and night. Some of these satellites are operated by ICEYE, a company based in Finland, while others are managed by its American subsidiary, ICEYE US. ICEYE-X36 is one of the latter.

At least some ICEYE satellites provide imagery to Ukraine, which Russia invaded in February 2022 and continues to assault with ground troops and missile and drone attacks. Indeed, ICEYE signed a contract this past January firming up this data-sharing relationship with Ukraine.

"The agreement ensures that the Ministry of Defence continues to receive a high volume of high-resolution satellite imagery through ICEYE's world-leading SAR constellation, supporting the Ukrainian Armed Forces with persistent situational awareness on tactical timelines," ICEYE representatives said in a January statement.

That likely explains Russia's interest in ICEYE satellites, which is extensive and longstanding. For example, Kosmos 2612 launched in April of this year with five other spacecraft. In May, four members of this fleet, including Kosmos 2612, conducted maneuvers to get into a co-planar orbit with ICEYE-X36. Such maneuvers use a lot of fuel and are therefore not performed lightly. (It's unclear if ICEYE-X36 is dedicated to capturing imagery of Ukraine or Russia, but Russia certainly seems to think it is.)

However, we still don't know the purpose of Kosmos 2612's close approach (which is apparently over, at least for now), Samson stressed.

There are a few possibilities. For example, Russia may want to get a better idea of ICEYE satellites' capabilities, and/or figure out what exactly they're studying on Earth below. Or maybe Kosmos 2612 was actively interfering with ICEYE-X36 in some way — messing with its sensors, perhaps, or blocking or intercepting its communications with the ground.

However, Samson leans toward another explanation.

"I think they're getting frustrated," she said of the Russians.

"They've been kind of in a stalemate, particularly for the past six months or so. And so I think it's just more a matter of demonstrating military prowess in a manner that the Ukrainians cannot respond to," she added. "The Ukrainians are just as good, perhaps even better than, the Russians on drones. But when it comes to space stuff, they're not peers, and this is just a way to remind everyone that that's the case."

As Kosmos 2612's activities show, space is becoming an increasingly competitive and contested domain. The U.S. has long held the advantage above Earth, fielding the most capable reconnaissance and communications craft, but Russia and China are challenging that dominance.

This drama is unfolding above our heads now, and it affects everyone on the planet. Samson therefore wishes that governments around the world were more forthcoming about their space activities — for example, that we learned about Kosmos 2612's shenanigans from the U.S .Space Force rather than from private companies and civilians who pore over government tracking data.

"I think it just speaks to the importance of transparency, and sharing information about these sort of things," she said. "As much as you may want to, you cannot keep the existence of satellites classified, because people can see them."

SpaceX will soon notch a huge spaceflight milestone, if all goes according to plan.

The company will try to catch both stages of its Starship megarocket during the vehicle's next test flight, which is targeted for next month, founder and CEO Elon Musk announced during SpaceX's quarter 3 (Q3) earnings call today (Oct. 20).

If SpaceX succeeds, this "will be the first time that an orbital launch vehicle has been fully recovered," Musk said. "The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle. So this is, I think, a profound technology milestone in the history of civilization and consciousness."

Starship is the biggest and most powerful rocket ever built, standing more than 400 feet (122 meters) tall when fully stacked.

As Musk noted, both of its stages — the Super Heavy booster and Ship spacecraft — are designed to be fully and rapidly reusable, a breakthrough that SpaceX thinks will make Mars settlement and other grand exploration feats economically feasible.

Starship's recovery strategy is different than that for SpaceX's Falcon 9 and Falcon Heavy rockets, which are partially reusable. (The latter two rockets have expendable upper stages). Falcon 9 and Falcon Heavy boosters come back to Earth on landing pads near the launch site or on ships at sea downrange. Super Heavy and Ship, however, will steer themselves directly back to their launch tower, which will capture each vehicle with its "chopstick" arms.

This will allow SpaceX to inspect, refurbish and refly Starship at an accelerated rate, which is a priority for the company: Musk has said he envisions launching Starship more than 10,000 times per year by 2030.

Starship has conducted 14 test flights to date, and SpaceX has pulled off chopstick catches with Super Heavy on three of them. The company has not yet tried to catch Ship, which is a more difficult proposition, as the upper stage travels higher, farther and faster than the booster does.

Still, Musk is confident that SpaceX will pull off a Ship catch on the first try. (He did not give a specific target date for Flight 15, saying only that it was expected next month.)

"I'd say it's more likely than not that this succeeds next flight," he said. "And if not, we have a steady stream of Starship flight attempts through the end of this year, and and then accelerating next year."

Success would mean back-to-back Starship flights with huge milestones. On Flight 14, which occurred on Sept. 28, Ship reached orbit for the first time ever. It also deployed 26 of SpaceX's Starlink Version 3 satellites — the first 26 members of a next-gen broadband constellation in low Earth orbit that will eventually consist of about 100,000 spacecraft.

The Starship Flight 15 preview was something of an aside during today's call. The event primarily served to announce SpaceX's financial performance during Q3, the three-month stretch that ended on Sept. 30.

And that performance was strong, company representatives said. SpaceX recorded revenues of $14.6 billion during Q3, an increase of 161% from the $5.6 billion earned during Q3 of 2025. The company had a net income of $4.4 billion during Q3, $5.5 billion better than the result from the same stretch last year, when SpaceX lost $1.1 billion.

Just $1.8 billion of 2026 Q3 revenue came from SpaceX's launch division. The vast majority was generated by two other segments — connectivity (services provided by its Starlink megaconstellation) and artificial intelligence (or, as the Trump administration has recently rebranded it, "superintelligence").

SpaceX thinks these latter two segments will continue to boom. That's why it's building the infrastructure to support thousands of Starship launches per year — to loft lots of Starlink satellites and AI data centers to Earth orbit. And the company believes that it's positioned to really start raking in the cash, starting as soon as next year.

"In a nutshell, what this implies for SpaceX annual recurring revenue by the end of '27 is somewhere between 500 billion [dollars] and a trillion," Musk said.

SpaceX just launched its mysterious "Starfall" return capsule for the second time ever.

Starfall was one of 32 payloads on the company's Bandwagon-5 rideshare mission, which launched atop a Falcon 9 rocket at 7:04 a.m. EDT (1104 GMT) today (Oct. 20) from Cape Canaveral Space Force Station in Florida.

SpaceX has been relatively quiet about Starfall, which debuted this past June on a Falcon 9 launch from the Cape.

That June 23 flight was a dedicated demonstration mission for Starfall, designed to show that the capsule can fly in a controlled fashion and survive the harrowing downward trip through Earth's atmosphere.

And those will be Starfall's main jobs. The vehicle "will enable affordable, routine access to the microgravity environment for scientific research and in-space manufacturing," SpaceX in a June 23 X post, one of the few public statements the company has made about Starfall.

Indeed, most of the details that we have about the capsule come from an environmental assessment that was published by the U.S. Federal Aviation Administration in May.

According to that document, the disk-shaped Starfall is roughly 2.5 feet (0.75 meters) tall and 10.2 feet (3.1 m) wide. It weighs about 4,600 pounds (2,100 kilograms) and can bring 2,200 pounds (1,000 kg) of payload back down to Earth.

Starfall wasn't the only return capsule that went up on Bandwagon-5. Among the other 31 payloads on the flight was W-Series 7, the latest orbital "mini-factory" built and operated by the California company Varda Space Industries.

The W-Series capsules are designed to both host the production of valuable goods such as pharmaceuticals and bring them safely down to Earth, Varda has said.

The other payloads on Bandwagon-5 are a mix of "cubesats and microsats," according to SpaceX's mission description. Among the latter is Pelican-12, a sharp-eyed Earth-observation satellite built by the San Francisco company Planet.

The 32 payloads were deployed over a two-hour span beginning about 57 minutes after launch. Starfall will be the last to separate, releasing from the Falcon 9's upper stage two hours and 48 minutes post-liftoff.

The Falcon 9's first stage, meanwhile, came back to Earth as planned on Bandwagon-5. It touched down about nine minutes after launch, coming down in the Atlantic Ocean atop the SpaceX drone ship "A Shortfall of Gravitas." It was the 19th mission for this particular booster, according to the company.

Bandwagon is one of two SpaceX rideshare programs. The other, known as Transporter, has been busier, flying 18 missions to date.

The first Transporter mission, which lifted off in January 2021, delivered 143 payloads to Earth orbit, a single-launch record that still stands.

Editor's note: Japan launched its bold MMX sample-return mission to the Mars moon Phobos on Oct. 19) at 3:41 p.m. EDT (1941 GMT).
Watch a replay of the liftoff and read our launch story here.

Japan will launch an epic mission to Mars today (Oct. 19), and you can watch the action live.

The Martian Moons eXploration (MMX) mission is scheduled to lift off atop an H3 rocket from Japan's Tanegashima Space Center today at 3:41 p.m. EDT (1941 GMT; 4:41 a.m. on Oct. 20 local Japan time).

You can watch it live via the Japan Aerospace Exploration Agency (JAXA). Coverage will begin at 2:45 p.m. EDT (1845 GMT).

As its full name suggests, MMX will focus on Mars' two moons, Phobos and Deimos. They're both tiny compared to Earth's own moon; Phobos is just 14 miles (22 kilometers) wide, and Deimos is even smaller, with a diameter of about 8 miles (13 km).

They're also quite mysterious. While astronomers have a pretty clear understanding of our own moon's birth — it coalesced from material blasted into space when a Mars-sized planet slammed into Earth long ago — there's no consensus about Phobos and Deimos' origin story.

The duo "may be the remains of a massive impact on Mars that sent material into orbit around the planet, or they could be ancient asteroids that were captured by Mars' gravity billions of years ago," Tom Statler, MMX program executive and program scientist at NASA Headquarters, said in an Oct. 15 statement. (NASA is a partner on the mission, providing a scientific instrument, a technology demonstration, communication support and funding for American scientists on the MMX team.)

"Having the answer will help illuminate that early era when Earth and the other inner planets may have been acquiring much of their water and organic compounds," Statler added.

MMX will help provide that answer, if all goes according to plan.

The spacecraft will arrive in the Mars system in August 2027, then slip into orbit around Phobos a month later. It will study that moon and Deimos from a distance for about 18 months, then deploy the French-German Idefix rover onto Phobos' surface in early 2029.

The 55-pound (25 kilograms) Idefix "has two main tasks: providing information to prepare for the landing of the main spacecraft to collect samples, and analyzing the composition and texture of Phobos' surface," European Space Agency officials wrote in an MMX mission description.

"The gravity on Phobos is so low that Idefix will only weigh the equivalent of 15 grams [0.5 ounces] on its surface!" they added.

The MMX mothership's Phobos landing will occur in 2030. The spacecraft will grab at least 10 grams (0.4 ounces) of samples from the moon, then head back toward Earth with this extraterrestrial bounty. MMX's return capsule will land here in 2031, after which scientists around the world will scrutinize the Phobos sample for clues about the history and evolution of Mars and our solar system more broadly.

MMX was originally supposed to launch in 2024, but issues with the H3 rocket prevented it from doing so. Mars and Earth align properly for interplanetary launches just once every 26 months, so MMX had to wait a while for its next chance.

Japan already has an impressive sample-return track record. The country's Hayabusa mission brought home pieces of the asteroid Itokawa in 2010, for example, and Hayabusa2 did the same with material from the space rock Ryugu a decade later.

The astronauts of SpaceX's Crew-12 mission to the International Space Station wish that we could all see Earth as they just did.

An orbital view reveals the immense beauty of our blue planet, the only world we know of that hosts life. But it also highlights how fragile that life is, tethered to our lonely Earth in the vast void of space, according to Crew-12 commander Jessica Meir of NASA.

"You see this very thin, tenuous band of an atmosphere, and you know that that is all that is supporting life, and we really need to do our best to protect it," Meir said on Thursday afternoon (Oct. 15), during a press conference that discussed the recently concluded Crew-12 mission.

"I wish that I could bring all the eyes of all the humans to look back at the Earth in this extraordinary way that we are so privileged to have," she added. "I think it really does change you philosophically and [in] how you see each other, how you see yourself, how you see the human race when you look on it down from the vantage point that we have from above — you know, [it] gives everybody this understanding that we need to protect our planet, that it's not only so beautiful, but it's so precious."

From the International Space Station (ISS), Meir said, it's clear that everything on Earth is connected — and that the borders we've laid down between states and nations are artificial constructs.

"You realize that we really are one human when you are in space," she said. "I wish I could share that perspective with all the eyes of all the humans. I think it would be a very healthy thing for everyone to understand.

Crew-12 mission specialist Andrey Fedyaev, of the Russian space agency Roscosmos, voiced similar sentiments, though he would turn an ISS visitor's eyes inward, to focus on the crew.

"I always say that the life of crewmembers on board the space station is the best example of how people need to live on Earth," Fedyaev said during Thursday's briefing (in Russian; in interpreter translated his words into English in real time)."

"We don't have borders. We are all friendly. We're just one crew, and the safety of the crew, the safety of the station, depends on the actions of the entire crew," he added. "So, if humankind does arrive at the same conclusion — that our Earth, our planet, is one and the same space vessel that flies through space — we need to take care of it and not to destroy it. So, that's what I would like to show to everyone on Earth."

Meir and Fedyaev are far from the only ones to have their perpsectives shifted by a space mission. Pretty much every astronaut experiences this phenomenon, which is known as the overview effect, a term coined in 1987 by space philosopher Frank White.

Crew-12 consisted of Meir, Fedyaev, NASA astronaut Jack Hathaway (the mission's pilot) and the European Space Agency's Sophie Adenot (mission specialist). It was the second spaceflight for Meir and Fedyaev and the first for Hathaway and Adenot.

The quartet launched toward the ISS on Feb. 13 atop a SpaceX Falcon 9 rocket. Their Crew Dragon capsule, named Freedom, arrived at the orbiting lab a day later.

Crew-12 spent nearly eight months aboard the ISS, finally returning to Earth on Oct. 8. They conducted a wide range of scientific experiments and maintenance work during that time and set a few records as well.

For example, Adenot became the first French woman ever to perform a spacewalk, and she broke the mark for longest continuous spaceflight by a European at 237 days. The previous record, 201 days, was set by Luca Parmitano in 2019-2020.

Well, that was a memorable debut.

Tesla unveiled its highly anticipated new Roadster last night (Oct. 16) with a spectacular stunt, using SpaceX thrusters to make the vehicle "fly."

"This is not necessarily a safety-optimized car, OK?" Elon Musk, who runs both companies, said during the livestreamed reveal, which was held at SpaceX's rocket-testing facility in McGregor, Texas. "But it takes the the fun meter to 11 out of 10."

Tesla first announced the next-gen Roadster in 2017, saying at the time that it would be released in 2020. In 2018, Musk announced that the new car would incorporate some SpaceX tech.

"SpaceX option package for new Tesla Roadster will include ~10 small rocket thrusters arranged seamlessly around car. These rocket engines dramatically improve acceleration, top speed, braking & cornering. Maybe they will even allow a Tesla to fly…" he wrote on Twitter in June of that year. (In 2022, Musk bought Twitter, which he subsequently renamed X.)

So last night's demonstration didn't come entirely out of left field — but it was still eye-popping. The show began with the Roadster driving up a ramp that quickly became a vertical wall and then an overhanging ledge. The Roadster clung to the surface, hanging upside-down from the ledge like a gecko on a ceiling thanks to a special fan suction system on its chassis.

"I mean, this car really sucks, OK?" Musk said, channeling his inner stand-up comedian. "This car could suck the chrome off a trailer hitch. It could suck a tennis ball through a hose pipe."

The suction feature is not just a novelty, he added: It will help the Roadster stay connected to the ground during high-speed turns, allowing drivers to corner incredibly well.

And the sucking was just an opening act. The Tesla soon launched itself from its position beneath the ramp's nearly horizontal ledge, executed a barrel roll in midair, and landed softly, all thanks to its SpaceX cold-gas thrusters.

"A friend of mine, Peter Thiel, once said that the future promised us flying cars, but instead we got 140 characters," Musk said after the Roadster touched down. "Well, not anymore."

The car has main thrusters in the rear, he explained, as well as attitude-control thrusters that control its orientation.

"So it can basically fly like a rocket, and it could do rolls," Musk said. "It could do, like, crazy gymnastics — whatever you want, really."

The Roadster has a total of 10 thrusters, which are fed by 600 liters — about 250 kilograms (550 pounds) — of compressed air, Tesla Engineering Vice President Lars Moravy said during last night's event. That air is housed in carbon fiber overwrapped pressure vessels, which fill "every usable void in the car," Tesla said via X last night.

The Tesla team put those thrusters to work multiple times during the presentation, at one point launching the Roadster over a line of six vehicles, including a Tesla semi-truck cab.

Nobody was behind the wheel during these stunts — nobody with a pulse, anyway. The driver's seat was occupied by a mannequin clad in a black-and-white SpaceX spacesuit.

This was a nod to "Starman," the dummy behind the wheel of Musk's cherry-red first-gen Roadster, which launched into orbit around the sun in February 2018 on the first-ever flight of SpaceX's Falcon Heavy rocket.

Starman and his Roadster are still in space, by the way, and will be for a while. Modeling work suggests the duo will keep orbiting our star for millions of years before ultimately slamming into either Earth or Venus.

Last night's Roadster demo was something of a tease, for the car is not yet in showrooms. Musk said Tesla aims to begin producing it in 2028.

And don't expect to see the "flying" version on the road then, or anytime; it's hard to imagine regulators certifying that vehicle for everyday use. It will likely be a status symbol for a few wealthy and connected folks, locked away in spacious and well-appointed garages.

Indeed, you can't put down on a deposit for the "Rocket" version of the new Roadster on Tesla's website; purchase of that vehicle is by invite only.

Two other Roadster versions are for sale — "Performance" and "Thrust." Tesla's website describes the Performance variant as "road ready," with "active aero and a multi-mode suction system." Thrust, by contrast, is "race ready." It has active aero and suction "plus acceleration thrusters."

It costs $50,000 to reserve a Performance vehicle and $250,000 to reserve a Thrust. Tesla has not yet revealed the total cost of any of the new Roadster variants.
