K2 Space raises $500M to build big, powerful satellites

K2 Space, a California-based satellite company that recently set up an engineering hub in Seattle, has announced a $500 million funding round at a $6.8 billion valuation.

The Series D round was led by Kleiner Perkins and ICONIQ, with participation from CapitalG, Lightspeed, Altimeter, Spark Capital, Sands Capital, ARK Invest, T. Rowe Price Associates and other existing investors.

Since its founding in 2022, K2 Space has raised more than $1 billion in capital and secured an equivalent amount in contracts.

While many satellite companies focus on miniaturization, K2 Space is going big on satellite mass and power. K2 had its first “mega-class” satellite, dubbed Gravitas, launched into orbit on a SpaceX Falcon 9 rocket in March. The two-ton, 20-kilowatt satellite carried a dozen undisclosed payload modules for multiple customers, including the Department of Defense.

Partners plan to make machines for moon construction

Seattle-based Interlune is expanding its partnership with Vermeer, an Iowa-based industrial equipment manufacturer, to develop construction tools for use on the moon.

The two companies forged their initial strategic partnership to further Interlune’s plans to extract helium-3 from tons of moon dirt and rocks, also known as regolith. Their full-scale prototype of a lunar excavator was unveiled a little more than a year ago.

At the time, Interlune was focused on mining helium-3 and bringing it back to Earth for applications ranging from quantum computing to medical imaging and nuclear fusion. But a major shift came in March when NASA announced a 10-year, $30 billion initiative to build the infrastructure for a moon base.

Interlune co-founder and CEO Rob Meyerson said he and his teammates realized that the partnership with Vermeer could support NASA’s plans. “We went back to Vermeer … and we decided that it made sense to formally expand the partnership to focus on all these other things that we’ve had in mind,” Meyerson told me.

For example, a lunar construction project is likely to involve building roads, compacting surfaces, digging trenches for underground utilities and moving rocks to clear space for a habitat. Heavy equipment might be needed to build protective berms around nuclear reactors.

Vermeer’s president and CEO, Jason Andringa, said he’s up for the challenge. He noted that before taking charge of the business his grandfather founded nearly 80 years ago, he was a staff engineer at NASA’s Jet Propulsion Laboratory.

“When I left NASA and came to work for Vermeer, my hope always was to be able to re-merge my passion for aerospace, specifically for the human exploration and human colonization of the moon and Mars, with my coming back to my family business … and use what I knew Vermeer was best at on Earth to do important work on the moon and Mars,” he told me.

Sophia Space wins a patent for cool orbital data centers

Sophia Space has secured a patent for a technology that could pave the way for solar-powered orbital data centers that passively radiate excess heat into space.

Developed in partnership with Caltech, Sophia’s architecture tackles a major hurdle in orbital computing: how to cool thousands of chips running artificial intelligence applications in space.

Traditional designs rely on satellite-wide radiator systems with heat pumps and circulating fluids. In contrast, Sophia plans to build flat, modular tiles equipped with four processors each. The tiles draw power from solar cells on their sunlit side, and shed heat into the cold vacuum of space from their dark side.

This approach avoids having to put a cooling system in the central bus of every satellite, said Leon Alkalai, Sophia Space’s co-founder, chairman and chief technology officer. “I think you will find in time that our approach is much more favorable when we scale to larger wattage systems, because bringing everything into a bus can only be done until a certain level, and then it becomes almost impossible to do,” he told me. “Our benefit is really scalability.”

How unorthodox routes can lead to the space frontier

The road to space isn’t always a straight line. Sometimes, the itinerary for a career in the space industry begins with years of experience in other tech fields. And sometimes, it starts at an espresso stand.

“I actually started as a barista at SpaceX, and I somehow got recruited to go build Starlink satellites,” Kayla VanderPutten, a technical recruiter at Anduril Industries, said Monday at a downtown Seattle Tech Week session focusing on the intersection of space and technology. “I don’t know why they let me do that, but I was there for the first 500 satellites before I transitioned into recruiting.”

Over the course of 25 years, Joydeep Hazra’s career path took him through a series of jobs in telecommunications and network engineering, including management positions at Nokia, Mavenir and TRIDENTX. Now he’s the manager of a federally funded program focusing on electric vehicles at South Seattle College — and he’s getting involved in aerospace as well.

Amazon plans 5,105 satellites for mobile connectivity

Amazon Leo has asked the Federal Communications Commission to approve its plan to launch up to 5,105 satellites capable of providing space-based connectivity for mobile devices.

“Our plan is to start deploying in 2028, and we’re excited to work with partners to make it happen,” Chris Weber, vice president of business and product for Amazon Leo, said on X.

The direct-to-device network, Amazon Leo D2D, would complement Amazon’s satellite network for high-speed internet service via fixed antennas. It would also leverage the existing direct-to-device network operated by Globalstar, which is in the midst of a merger with Amazon.

So far, more than 390 Amazon Leo satellites have been launched into low Earth orbit. Amazon says it plans to start rolling out commercial service later this year. The company plans to have 3,232 first-generation satellites in orbit by mid-2029, and the FCC has already given the go-ahead for more than 4,500 second-generation satellites that would give an extra boost to network coverage.

This latest move, which was expected ever since the plans for acquiring Globalstar were announced in April, aims to capitalize on the growing interest in direct-to-device connectivity.

NASA funds research into nuclear heaters for astronauts

NASA says it’s funding a new batch of far-out research projects, including a study evaluating how radioactive heaters can keep astronauts warm while they work on the moon.

The heating project was proposed by Zeno Power Systems, a nuclear battery company with operations in Seattle, California and Washington, D.C. It’s one of 18 projects selected for nine-month, $175,000 Phase I grants by the NASA Innovative Advanced Concepts program. For decades, NIAC grants have helped researchers test concepts with potential space applications.

Zeno’s research project is led by A.C. Charania, the company’s senior vice president of space business development. Charania previously spent two years as NASA’s chief technologist and five years in management roles at Jeff Bezos’ Blue Origin space venture.

The project comes with an acronym taken from J.R.R. Tolkien’s tales of Middle-earth: EARENDIL, which stands for Extended Astronaut Radioisotope-EVA in Nighttime and Deep-Space Icy Landscapes. In “The Silmarillion,” Eärendil is a half-Elven mariner who voyaged to the Undying Lands. As described in Zeno’s proposal, EARENDIL technology would warm space voyagers while they work outside during the frigid lunar night, amid temperatures that can plunge as low as 410 degrees below zero Fahrenheit (-246 degrees Celsius).

Zeno is already developing a new class of compact nuclear devices powered by the heat of radioactive decay. One type of device would convert that heat into electricity, but the device proposed for EARENDIL would function strictly as a heater rather than a battery.

Lucky 13! Starship sends out satellites and stays intact

SpaceX’s Starship super-rocket deployed operational next-generation Starlink satellites for the first time during its 13th flight test, which addressed snags that arose in the previous test.

The 407-foot-tall, two-stage rocket rose from its Starbase launch pad in Texas at 5:51 p.m. CT (3:51 p.m. PT) today, with all 33 Raptor engines firing on the Super Heavy booster. On the way up, the rocket set a record for maximum dynamic pressure, also known as Max-Q.

Minutes after liftoff, the Starship upper stage — known as Ship — separated to continue on the flight test’s trajectory, and then the booster relit its engines for a controlled splashdown in the Gulf of Mexico. SpaceX launch commentator Dan Huot noted that not all of the engines fired up as planned — making for a splash that was a bit spicier than expected but still safe.

Mars Society plans to put research station in Seattle

The Mars Society is planning to build a Pacific Northwest research station suitable for simulating missions to the moon or Mars, in partnership with South Seattle College.

The nonprofit space advocacy group announced today that its executive director, James L. Burk, and the college’s president, Monica Brown, have signed a 10-year memorandum of agreement establishing the partnership.

The plan calls for the Mars Society to lease land on the college’s 87-acre West Seattle campus and build the research station, contingent on funding. Both parties will raise funds from aerospace companies and other donors to support construction, with the goal of opening the station at the start of the 2027-2028 academic year.

The agreement provides for the creation of a joint space studies curriculum and certificate program; a student capstone project and internship program tied to industry partners; and a regional workforce pipeline and community engagement effort.

Interlune comes up with a cool way to produce helium-3

Seattle-based Interlune says it has managed to produce 99% pure helium-3 from a standard supply of industrial-grade helium, marking a milestone for a technology that the company aims to use on the moon.

The process, known as Cold Capture, could be profitably used on Earth even before Interlune begins lunar mining operations.

Only 0.000137% of the world’s helium exists in the form of helium-3, as opposed to the much more common helium-4 isotope. But helium-3 is uniquely suited for use as a refrigerant for quantum computers. It can also be used in radiation detectorsmedical scanners and eventually fusion reactors.

Because of its rarity and utility, the price of helium-3 can range as high as $20 million per kilogram ($9 million per pound). Interlune is betting on the proposition that helium-3 is more abundant and easier to access on the moon, due to the lunar surface’s exposure to the solar wind. If Interlune’s business model works out, it will be able to turn a profit by delivering lunar helium-3 to Earth for industrial applications.

TerraByte takes its ‘Earth Search Engine’ to the next level

Two months after emerging from stealth mode, TerraByte AI is using artificial intelligence and a new partnership to upgrade its “Earth Search Engine.”

The startup, which maintains operations in Seattle as well as San Francisco, has just rolled out a TerraByte News service that pinpoints wildfires, earthquakes and severe weather events on an interactive map. Users can follow links to access news reports, social media posts and satellite views related to selected events.

The satellite views include open-source images from NASA’s Earth observation system as well as Europe’s Sentinel satellites. And now the database also features high-resolution pictures provided through a newly announced partnership with Texas-based SkyFi. The partnership gives TerraByte’s users access to SkyFi’s self-service Earth intelligence platform, which offers satellite and aerial imagery from more than 300 sources at prices as low as $15 per image.

“In May, when we came out of stealth, we made the planet searchable,” TerraByte CEO Rishi Madhok told me. “Now, the moment you find something, you can hold the imagery in your hands within a day. The next step is making Earth intelligence as routine as a web search — you ask, you see, and then you act.”
