Blue Origin jumps into the data center space race

Jeff Bezos’ Blue Origin space venture is asking the Federal Communications Commission for authority to send up to 51,600 data center satellites into low Earth orbit, signaling its entry into an increasingly crowded space race.

The proposed constellation, dubbed Project Sunrise, would complement Blue Origin’s previously announced plans for a 5,408-satellite TeraWave constellation. TeraWave would provide ultra-high-speed connectivity for Project Sunrise’s satellites — and for terrestrial data centers, large-scale enterprises and government customers as well.

Once again, Bezos is competing with Elon Musk’s SpaceX, which is seeking the FCC’s approval for a constellation of data centers that could amount to a million satellites. And SpaceX has already taken notice. So has Redmond, Wash.-based Starcloud, which is working on its own plans for a data center network that could call for tens of thousands of satellites.

Tech companies are becoming increasingly interested in fielding orbital data centers because such networks could bypass the power and cooling constraints facing Earth-based AI data centers. Last October, Bezos said at a tech conference in Italy that orbital data centers would be the “next step” in a transition from Earth-based to space-based industry. “We will be able to beat the cost of terrestrial data centers in space in the next couple of decades,” he said.

Bothell, Wash.-based Portal Space Systems is partnering with an Australian venture called Paladin Space on a commercial service that would round up and dispose of potentially dangerous orbital debris.

The concept — known as Debris Removal as a Service, or DRAAS — is meant to address one of the most pernicious problems facing spacecraft operators: how to dodge tens of thousands of pieces of space junk that are zipping through Earth orbit.

Since its founding in 2021, Portal has been focusing on the development of maneuverable orbital vehicles that could rendezvous with other satellites, either for servicing or for disposal. Its flagship is the Supernova in-space mobility platform, which will be equipped with an innovative solar thermal propulsion system. There’ll also be a smaller version of the spacecraft, called Starburst.

Starburst-1 is due for launch as early as this year, and Supernova is scheduled to make its debut in 2027.

Meanwhile, Paladin Space has been working on a reusable payload called Triton, which is designed to track and capture tumbling pieces of orbital debris that are less than 1 meter (3 feet) in size. That small-to-medium size category accounts for most of the debris that’s being tracked in orbit.

“Triton is built to remove dozens of those objects in a single mission, which fundamentally changes the cost structure of debris remediation and provides the greatest benefit to satellite operators,” Paladin CEO Harrison Box said today in a news release.

The Portal-Paladin partnership calls for installing Triton hardware on Starburst spacecraft. Portal’s orbital platform would go out in search of space junk, and Paladin’s payload would grab the debris. When Triton’s trash bin is full, it would be dropped off for safe disposal while the spacecraft remains in orbit for continued servicing.

The companies are targeting an initial deployment in 2027, focusing on heavily trafficked bands of low Earth orbit. Future missions may use Supernova’s added capabilities to service a wider variety of orbits.

A quick guide to the total lunar eclipse — and the weather

Tonight’s full moon will turn into a red moon during the last total lunar eclipse we’ll be able to see for the next two years — but whether we’ll truly be able to see it with our own eyes depends on the weather. And that’s an iffy proposition for Pacific Northwest skywatchers.

The good news is that total lunar eclipses, unlike a total solar eclipse, can be seen from an entire hemisphere at a time. They occur when the orbital mechanics are just right for Earth to pass directly between the moon and the sun. For about an hour, Earth’s shadow blots out the sun’s rays, except for reddish wavelengths that are refracted by our planet’s atmosphere. That’s what lends the moon its blood-red color.

Tonight’s eclipse begins with a barely discernable penumbral phase at around 1:30 a.m. PT March 3, gets into its partial phase at 1:50 a.m. and enters totality at 3:04 a.m. The eclipse’s total phase ends at 4:03 a.m., and the partial phase winds down over the following hour or two.

NASA overhauls moon plan — and Blue Origin may benefit

NASA is reworking its Artemis moon program to add a test mission for commercial lunar landers in low Earth orbit next year, with a crewed lunar landing to follow in 2028 at the earliest. The revised plan raises the profile of the Blue Moon lander that’s being built by Jeff Bezos’ Blue Origin space venture.

“We’re all in!” Blue Origin CEO Dave Limp said in a post to X.

NASA Administrator Jared Isaacman, who took up his post last December, announced the schedule shift today. “This is going to be our pathway back to the moon,” he said.

The next step in the pathway is the same as it has been: NASA is getting set to use its giant Space Launch System rocket to launch four astronauts on a 10-day trip around the moon in an Orion capsule. That Artemis 2 mission is currently set for no earlier than April, due to a helium leak that forced this week’s rocket rollback from the launch pad for troubleshooting.

NASA’s previous plan called for following up on Artemis 2 with a crewed lunar landing next year for Artemis 3. However, the development of the SpaceX Starship lander for that mission has proceeded more slowly than expected.

Under the revised architecture, Artemis 3 becomes a crewed orbital test for SpaceX’s Starship and/or Blue Origin’s Blue Moon lander. The mission could also test the next-generation spacesuits that are being developed for extravehicular activities. The Artemis program’s first crewed lunar landing would follow in 2028, presumably using either Starship or Blue Moon.

Rubin Observatory revs up its astronomical alert system

An astronomical alert system developed at the University of Washington started off with a bang this week, sending out 800,000 notifications about moving asteroids, exploding stars and other celestial changes detected by the Vera C. Rubin Observatory in Chile.

That Feb. 24 surge was just the first wave. Eventually, the Alert Production Pipeline is expected to produce up to 7 million alerts per night. Astronomers will use the system to sift through the torrent of data, zeroing in on events ranging from newly detected asteroids to supernovas, variable stars and active galactic nuclei.

“Rubin’s alert system was designed to allow anyone to identify interesting astronomical events with enough notice to rapidly obtain time-critical follow-up observations,” Eric Bellm, a UW astronomer who leads the Alert Production Pipeline Group for the Rubin Observatory, said today in a news release. “Rubin will survey the sky at an unprecedented scale and allow us to find the most rare and unusual objects in the universe. We can’t wait to see the exciting science that comes from these data.”

Sophia Space says it has closed a $10 million seed financing round to accelerate the development of orbital computing systems that could serve as the foundation for space-based data processing.

The startup’s tabletop-sized satellite modules, known as tiles, take advantage of a proprietary system that combines solar power generation and radiative cooling. Multiple tiles can be connected into racks to provide scalable computing power in low Earth orbit. The concept is called Thermal-Integrated LEO Edge, or TILE.

“With this seed round, we’re not just building compute modules,” Sophia Space CEO Rob DeMillo said today in a news release. “We’re building the infrastructure for the next era of space-based AI and data processing.”

The investment round was led by Alpha Funds, KDDI Green Partners Fund and Unlock Venture Partners — and builds upon $3.5 million in pre-seed investment. The newly raised cash will support the continued hiring of engineering talent, the further maturation of Sophia’s TILE platform and the formation of strategic partnerships in the orbital computing ecosystem.

Helium problem forces NASA to delay moon mission

NASA Administrator Jared Isaacman says the giant rocket set to send four astronauts around the moon for the history-making Artemis 2 mission must be rolled back from its launch pad to troubleshoot a technical problem.

The 10-day mission, previously scheduled for as soon as March, is now postponed until April at the earliest. “I understand people are disappointed by this development,” Isaacman said in a posting to X. “That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor.”

The technical issue cropped up just days after a successful launch-pad rehearsal at NASA’s Kennedy Space Center. Data from the Space Launch System rocket’s upper stage registered an interruption in the flow of helium, which is used to pressurize the propellant tanks and purge the engines. “Last evening, the team was unable to get helium flow through the vehicle,” Isaacman wrote today. “This occurred during a routine operation to repressurize the system.”

Isaacman said the helium pressurization system worked correctly during this week’s wet dress rehearsal. For what it’s worth, a problem with a helium valve cropped up during preparations for the uncrewed Artemis 1 round-the-moon mission in 2022, leading NASA managers to take corrective actions.

The current problem could be due to a failure at any of several points in the helium system. “Regardless of the potential fault, accessing and remediating any of these issues can only be performed in the VAB,” said Isaacman, referring to the 52-story Vehicle Assembly Building where the SLS and its Orion crew capsule were stacked for launch.

NASA completes rehearsal for Artemis moon launch

NASA counted down to T-minus 29 seconds during a smooth rehearsal for a historic launch that could send astronauts around the moon for the first time in more than half a century.

The run-through at Launch Complex 39B, at Kennedy Space Center in Florida, was known as a wet dress rehearsal because it involved filling up the propellant tanks on NASA’s Space Launch System, a 322-foot-tall rocket that made its debut with 2022’s uncrewed Artemis 1 mission.

The only major component that was missing at the launch pad was the crew. NASA astronaut Reid Wiseman, the commander for the Artemis 2 mission, said in a posting to X that he was watching the proceedings from Launch Control.

Once NASA reviews the results of the two-day rehearsal, mission managers will decide whether to give the final go-ahead for the Artemis 2 crew’s 10-day trip around the moon and back.

Lori Glaze, acting associate administrator for NASA’s Exploration Systems Development Mission Directorate, said the space agency is targeting March 6 for liftoff. “Every night I look at the moon, and I see it, and I get real excited because I can really feel she’s calling us,” she told reporters today. “And we’re ready.”

Amazon has won the Federal Communications Commission’s approval to go ahead with its plan to launch thousands of second-generation Amazon Leo satellites for its broadband internet network, even though the first-generation constellation is far from complete.

The approval would add more than 4,500 satellites to the previously authorized constellation of 3,232 Gen 1 spacecraft, expanding coverage to the entire globe, including the poles.

“Amazon Leo Gen 1 performance is impressive on its own, but lots to look forward to with Leo Gen 2: More capacity, more coverage (including polar) and additional throughput — good for customers everywhere, and especially important for big enterprise/gov customers who want max performance to move large amounts of data through our network,” Rajeev Badyal, vice president of technology for Amazon Leo, said today in a LinkedIn posting.
