Some satellite companies still have an appetite for boutique launch services

11 September 2026 at 19:34

If you ask most satellite companies aside from SpaceX, they will tell you the world doesn't have enough capacity for launching payloads into orbit. This is despite the blistering launch cadence we've seen around the world in recent years, led by SpaceX's Falcon 9 rocket.

Customers in any sector will, of course, usually welcome competition. Theoretically, competition will lead to lower prices and allow the best to rise to the top. It seems like the customers buying launch services were right. SpaceX is dialing back its Falcon 9 launch program, and there is no certainty about when SpaceX's reusable next-generation super-heavy-lift rocket, Starship, will carry anything to orbit besides the company's own Starlink satellites.

So it's no surprise satellite operators are cheering the success of a new launch provider. This was especially the case a few days ago, when Germany's Isar Aerospace reached orbit for the first time with its Spectrum rocket. The launcher delivered a batch of CubeSats to low-Earth orbit from a spaceport in northern Norway, and Isar tasted success after its first test flight ended in failure last year.

Could United Launch Alliance's money problems finally force its owners to sell?

11 September 2026 at 07:00

Pretty much every rocket company in the United States, save one, has embraced two fundamental tenets: reusability and diversification.

Most famously, SpaceX branched out from reusable rockets to pursue and dominate a growing spectrum of space services: cargo delivery, human spaceflight, satellite production, broadband, and, perhaps soon, orbital data centers and in-space manufacturing. Blue Origin is evolving from a pure rocket company into a satellite manufacturer, robotics developer, and, most recently, a potential competitor for SpaceX's Starlink network.

Rocket Lab used a different approach to diversify after achieving success with its small Electron launch vehicle. The company relocated its headquarters from New Zealand to Southern California, started building spacecraft and payloads, and then went on a spree of corporate acquisitions to expand into satellite communications and take on a new role as a merchant supplier of satellite components and sensors. It's now in a stage of advanced development of its partially reusable next-generation Neutron launch vehicle.

Rocket Report: Europe joins the commercial launch club; a Ravn X sighting?

11 September 2026 at 07:00

Welcome to Edition 9.10 of the Rocket Report! This week we're celebrating a historic moment in Europe when a German rocket company successfully put its launch vehicle into orbit. Isar Aerospace became the first purely commercial European company to reach orbit, and impressively it did so on just its second launch attempt. How quickly can they scale up operations? How quickly will the second European launch firm reach this goal? Big questions, which for now we don't have answers to.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Isar Aerospace takes a huge step forward.

Europe will go it alone on Venus mission after NASA yanks radar instrument

10 September 2026 at 15:09

The European Space Agency is moving "full steam ahead" with development of a robotic mission to Venus after NASA officials determined they were unlikely to fulfill a commitment to provide a US-built radar instrument for the spacecraft, the mission's project scientist said.

The European orbiter, named Envision, will map the Venusian surface at 10 times higher resolution than the last radar mission sent to Venus by NASA in the 1990s. The planet is enshrouded in a blanket of thick clouds of sulfuric acid, rendering its mysterious surface unseen by optical cameras in orbit. Radar is the most effective way to penetrate the clouds of Venus to reveal the terrain below, and scientists will use Envision to look for signs of active volcanism.

NASA and ESA signed a memorandum of understanding in 2024 outlining their partnership on Envision. NASA agreed to supply a US-made synthetic aperture radar instrument, Envision's primary means of mapping the surface of Venus, along with providing tracking and communications support through NASA's Deep Space Network. In exchange, ESA would include US researchers on Envision's science team. Europe would build the Envision spacecraft and the rest of its science instruments and provide the launch on an Ariane 6 rocket.

Artemis II commander and pilot become NASA's first astronaut emeriti

10 September 2026 at 07:30

The commander and pilot of NASA's Artemis II mission have gained a new distinction five months after splashing down from the Moon: They're not fully retiring from the space agency.

Reid Wiseman and Victor Glover are the first astronauts to join NASA's emeritus program, enabling them to continue to support the work being done at Johnson Space Center in Houston. They will remain available to train and mentor the current workforce while still being able to pursue employment and opportunities outside of NASA.

"I have asked NASA ... to not use the term 'retire' as much, but technically emeritus is a retirement program," Glover told collectSPACE.com on Wednesday. "It's something we have typically done for scientists when they have groundbreaking research, and they want to go back to academia to teach or to research and publish."

Europe may finally have found a space entrepreneur who is meeting the moment

9 September 2026 at 16:27

All of a sudden, French entrepreneur Hèlene Huby is seemingly everywhere.

This week she is serving as one of two envoys, alongside astronaut Thomas Pesquet, at a high-profile International Space Summit convened by French President Emmanuel Macron. The government's website for the event describes her as chief executive of "the fastest-growing space company in Europe."

Also this week, that firm, The Exploration Company, announced a significant capital raise of $450 million in Series C funding. Although not spectacular by the standards of some US space businesses, this is the largest-ever Series C funding round by a Europe-based space company, and likely the largest funding round ever raised by a female-led company in Europe.

The universal language of space is... Star Trek? Mais oui.

8 September 2026 at 16:20

Sixty years after television audiences first tuned in to see the voyages of the Starship Enterprise, an astronaut on board the International Space Station has paid tribute to Star Trek by flying the badge of the franchise's latest fictional captain.

Expedition 75 flight engineer Sophie Adenot with European Space Agency (ESA) donned the Delta badge originally worn by actor Anson Mount for a video recorded from aboard the space station. Mount portrays Christoper Pike in the Paramount+ streaming series Star Trek: Strange New Worlds. Paramount and ESA both released the clip on their Instagram feeds.

"For 60 years, Star Trek has brought us stories of friendship and exploration. I'm wearing Captain Pike's badge aboard the ISS in celebration of continuing the real world work of science and exploration," said Adenot. "For me, exploration and science are about curiosity and cooperation daring to go a little farther together, learning from what we discover and build, and turning that knowledge into a better future for everyone."

The secret to protecting next-gen spacecraft might be eggshells

8 September 2026 at 12:20

In 2007, a piece of space debris punched a bullet-like hole through the radiator panel of the US space shuttle Endeavor. The shuttle program ended in 2011, but the space debris problem has only intensifiedΒ as we launch more and more satellite constellations, telescopes, and spacecraft into orbit. That's why Chinese scientists have devised a new aluminum material inspired by eggshells that they believe could offer enhanced protection against debris fragments, according to a new paper published in the Journal of Applied Physics.

Eggshells have long fascinated scientists because of their mechanical properties. For instance, it's well known that cracking an egg requires applying just enough force to the center to achieve a clean break without completely shattering the shell. In 2012, MIT mechanical engineer Pedro Reis co-authored a paper demonstrating the link between an egg's ovoid geometry and its rigidity, a major factor when predicting how much force an object can endure before cracking. (As I wrote for Slate at the time, rigidity is related to, but distinct from, strength. If one eggshell has tiny cracks and the other doesn't, both shells have different strengthsβ€”the cracked one will break more easilyβ€”but the same rigidity.)

Reis started studying eggshells after participating in a popular physics demonstration: walking on cartons of eggs without breaking them. The key, he learned, was to align the eggs with their narrow tip (the most crack-resistant part) pointing up, and then carefully place one's feet to distribute one's weight over the entire surface area. This ensures that no single egg is overloaded. While it takes around 5.5 pounds of force to crack an egg, that depends on the direction in which the force is applied, as well as its distribution over the shell's surface.

With another huge infusion of cash, Stoke Space goes even bigger

8 September 2026 at 08:29

Stoke Space announced Tuesday that it has raised another significant round of funding, $1 billion, as it makes a final push toward its debut launch next year. The Washington-based launch company also revealed plans for a larger medium-lift vehicle.

With the Series E funding round, co-led by Point72 Ventures and Spark Capital, Stoke Space brought its total amount of capital raised to $2.3 billion, a staggering amount for a company that has yet to attempt an orbital launch.

The quantity of new funding will enable the company to accelerate work on a larger "Block 2" version of the Nova rocket, capable of lifting 15 metric tons to low-Earth orbit in a fully reusable configuration, said Stoke co-founder and Chief Executive Andy Lapsa.

German company becomes first in Europe to launch fully commercial orbital rocket

6 September 2026 at 07:55

Isar Aerospace, founded in 2018 by three students at a German university, successfully launched a privately developed rocket into low-Earth orbit Saturday from a Norwegian spaceport inside the Arctic Circle.

The two-stage rocket, named Spectrum, became the first fully commercial launch vehicle in Europe to reach orbit. With Saturday's success, Isar is the clear leader among a pack of several European launch startups vying to inject some competition into Europe's stagnant launch market.

Isar's 92-foot-tall (28-meter) Spectrum rocket lifted off at 4:12 pm EST (20:12 UTC) Saturday from AndΓΈya Spaceport in northern Norway, where it was 10:12 pm local time and the final bluish hues of daylight faded from the late summer sky. Seven minutes later, the rocket was in orbit.

After 8 years, Europe's BepiColombo mission is on final approach to Mercury

4 September 2026 at 18:49

The BepiColombo mission cleared a major milestone this week in the final stretch of an eight-year interplanetary voyage to Mercury, the hard-to-reach, scorching hot iron world at the Solar System's innermost frontier.

The robotic science mission, with a price tag of nearly $2 billion, is led by the European Space Agency with contributions from Japan and the United States. Since its launch in 2018, BepiColombo has spiraled closer to the Sun using a combination of plasma propulsion and a series of flybys of Earth, Venus, and Mercury. The maneuvers changed the spacecraft's velocity and steered it toward a final encounter with Mercury later this year.

Next time it reaches Mercury, BepiColombo will be traveling at just the right speed for the planet's gravity to capture the spacecraft into orbit. Scientists working on interplanetary missions are accustomed to long waits for scientific payoffs. It took nearly 10 years for NASA's New Horizons spacecraft to travel from Earth to Pluto. It turns out traveling to fleet-footed Mercury and then entering orbit requires more energy, or delta-v, than sending a probe to fly by Pluto.

Trump White House just tossed a grenade into international space relations

4 September 2026 at 11:46

The normally genteel world of international space policy turned ugly this week as several prominent US space companiesβ€”including SpaceX, Blue Origin, Stoke Space, K2, and Starcloudβ€”pulled out of a high-profile French space summit organized by the country's president, Emmanuel Macron.

Politico first reported the diplomatic turmoil, saying that the White House "pressured" US space companies to skip Macron's space summit in Paris next week. Since then, the companies have largely pulled out of the meeting without commenting publicly, though some US representation remains on the two-day program.

Multiple sources confirmed to Ars that an official with the White House Office of Science and Technology Policy, or OSTP, led the call with US space companies late last week. The call was convened in response to queries from US industry about the French meeting, which is not part of the traditional circuit of international space conferences.

Rocket Report: Engines installed for Artemis III; Long March 6C breakup in LEO

4 September 2026 at 08:48

Welcome to Edition 9.09 of the Rocket Report! This edition includes an update from Blue Origin on the groundbreaking of a new Payload Processing Facility in Florida. It has been about a month since the company offered any meaningful news on its heavy-lift New Glenn rocket, which remains grounded after an on-pad explosion at Cape Canaveral Space Force Station in May. The official line from Blue Origin is that the company is targeting a return to flight with New Glenn by the end of the year, but there's good reason for skepticism.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Isar Aerospace is ready to try again. Isar Aerospace is about to make the next attempt to launch the Spectrum rocket into orbit, with a weeklong launch window set to open Friday at AndΓΈya Spaceport in Norway, the Norwegian Broadcasting Corporation (NRK) reports. The German launch company aims to deliver several small CubeSats to orbit with the two-stage Spectrum rocket. A test flight of the privately funded launcher failed shortly after liftoff last year, and Isar has attempted to launch the second Spectrum rocket several times since January, only to be thwarted by technical problems and the unavailability of the launch range in northern Norway.

Wary of Artemis IV timeline, NASA is changing lunar spacesuit design

2 September 2026 at 15:37

NASA has decided to use a simpler spacesuit for its initial missions to the lunar surface, Ars has learned.

The agency announced the decision during an internal meeting this week as it seeks to accelerate its program to land humans at the south pole of the Moon as early as 2028. At the direction of Artemis Program Manager Jeremy Parsons, NASA will work with Axiom Space to develop a "Sortie Suit" variant of the planned spacesuit for the lunar surface.

Sources said the Sortie Suit will be used for the initial landing missions flown on landers developed both by SpaceX and Blue Origin. Among the goals of the initiative are to lower the mass of the spacesuit, reduce its complexity, and simplify interfaces between the spacesuits and lunar landers.

Toyohiro Akiyama, first Japanese citizen and journalist in space, dies at 84

2 September 2026 at 10:47

The first Japanese citizen to launch into space, Toyohiro Akiyama was also the first commercially sponsored cosmonaut and the world's first journalist to file reports while on a spaceflight.

Akiyama, 84, died last Wednesday, August 26, of lower gastrointestinal bleeding, news agencies in Japan reported. A funeral was held with his close relatives in attendance.

As a correspondent for the Tokyo Broadcasting System (TBS), Akiyama was chosen out of his 162 fellow employees who applied to fly to space in celebration of the network's 40th anniversary. He trained at the Gagarin Cosmonaut Training Center in Star City, located outside of Moscow, and was assigned to the Soyuz TM-11 crew.

Is Russia's rival to Starlink failing? Here's what we know.

2 September 2026 at 07:15

Russia's attempt to replicate SpaceX's Starlink satellite network seems to be moving as slowly as the front lines in eastern Ukraine.

The Rassvet program, often billed as Russia's answer to Starlink, started launching its first operational satellites earlier this year. Two launches, one in March and a second in July, have delivered 32 Rassvet satellites to low-Earth orbit, some 10 percent of the roughly 300 Rassvet spacecraft Russia aims to put into orbit by the end of next year to provide connectivity for military and civilian users. The company in charge of Rassvet, Bureau 1440, wants to deploy 924 satellites by 2035.

But none of the 32 satellites launched so far have reached the 500-mile (800-kilometer) orbit they were designed to operate in. The rockets that launched the first two batches of Rassvets released the satellites much closer to Earth, and the satellites were expected to use their own plasma engines to raise their orbits over the next few months.

It turns out that Orion's much-maligned heat shield performed really well

1 September 2026 at 10:46

Perhaps the biggest question going into the Artemis II mission this spring was how the heat shield at the base of the spacecraft would perform during reentry through Earth's atmosphere.

The ablative heat shield, designed to char upon reentry while keeping the crew safe, had experienced unexpected losses of large chunks during a test flight in late 2022. After much deliberation, and not without controversy, NASA decided to fly the Artemis II heat shield as is but modify the spacecraft's reentry trajectory.

Obviously, the heat shield worked. The crew of Artemis II, led by commander Reid Wiseman, safely splashed down in the Pacific Ocean after a triumphant trip around the Moon. Afterward, they and other NASA officials offered general comments, saying the heat shield looked good.

Without new landers or rovers, it's helicopters or bust for NASA's Mars program

1 September 2026 at 07:00

For the first time in more than 30 years, NASA has no firm plans to send any new landers or rovers to Mars. Instead, the agency's near-term focus at the red planet is on aerial drones, a pioneering mode of exploration that didn't seem realistic until a few years ago.

The first real use of drones for science at Mars will come with the SkyFall mission, a fleet of three helicopters set for launch as soon as late 2028. SkyFall's helicopters will ride to the red planet with NASA's Space Reactor-1 "Freedom" mission, which has the primary objective of demonstrating nuclear electric propulsion in deep space.

The launch schedule is aggressive for SR-1 Freedom and SkyFall, projects that didn't even exist in NASA's portfolio six months ago. NASA's plan for the SR-1 Freedom mission, estimated to cost $2.1 billion, calls for repurposing the core module of the canceled Gateway lunar space station into a testbed for nuclear electric propulsion. SkyFall will build on NASA's success with the Ingenuity helicopter, an experimental vehicle that became the first rotorcraft to fly on another world in 2021.

Private group wants to launch "cheapest possible" mission to Alpha Centauri

1 September 2026 at 06:00

There are, by various estimates, several trillion planets within what is known as the Local Group of galaxiesβ€”our closest galaxy neighbors, including our own Milky Way. Many of these planets are within the habitable zone of their stars. So if life finds a way, where are the alien civilizations?

This is the crux of what is known as the Fermi paradox, which posits that if life is fairly common in the Universe, humans should have collected credible evidence for the existence of extraterrestrial civilizations by now. People who think about this paradox believe there may be some "filter" that limits or entirely prevents an advanced civilization from sending out probes or even life-bearing spacecraft to nearby stars.

Philip Johnston is someone who thinks a lot about the Fermi paradox. A mathematician and physicist from the United Kingdom, Johnston has gained some notoriety lately in the space community as one of the biggest proponents of orbital data centers. He co-founded Starcloud in 2024 to develop such data centers, and the company is presently valued at $2.3 billion.
