The Vera C. Rubin Observatory’s science team has discovered more than 11,000 new asteroids — a feat made possible by the Simonyi Survey Telescope’s advanced capabilities and data-crunching software developed at the University of Washington.

Rubin’s deluge of discoveries, based on a million early-stage observations that were collected over the course of a month and a half last summer, includes roughly 380 trans-Neptunian objects, or TNOs, and 33 previously unknown near-Earth objects. (Don’t panic: None of those near-Earth objects poses a threat to Earth.)

The data set also includes more than 80,000 previously known asteroids, some of which had been “lost” to science because of uncertainty about their orbits. The findings were confirmed by the International Astronomical Union’s Minor Planet Center, the global clearinghouse for small solar system objects.

These aren’t the first finds for the $800 million observatory in Chile, which made its “First Look” debut last June. Astronomers previously reported finding more than 1,500 asteroids during earlier test rounds.

“This first large submission after Rubin First Look is just the tip of the iceberg and shows that the observatory is ready,” UW astronomer Mario Jurić, who heads Rubin’s solar system team, said in a news release. “What used to take years or decades to discover, Rubin will unearth in months. We are beginning to deliver on Rubin’s promise to fundamentally reshape our inventory of the solar system and open the door to discoveries we haven’t yet imagined.”

NASA’s Artemis 2 astronauts are sharing perspectives of Earth that haven’t been seen by human eyes for more than 50 years — from a spaceship that’s traveling from our home planet to the moon.

Two days after the launch of the crew’s Orion space capsule, the first high-resolution photos looking back at Earth are hitting NASA’s image repository. “You guys look great,” astronaut Christina Koch said.

Today’s star of the show is a blue-marble photo captured by mission commander Reid Wiseman after Orion completed its translunar injection burn and headed outward from Earth orbit on April 2. The faint greenish glint of auroras can be seen at upper right and lower left. The brighter glow of zodiacal light is visible at lower right.

“You could see the entire globe, from pole to pole,” Wiseman said during a news briefing. “You could see Africa, Europe, and if you looked really close, you could see the northern lights. It was the most spectacular moment, and it paused all four of us in our tracks.”

NASA’s Orion space capsule successfully fired its main engine today for a maneuver that sent the four astronauts of the Artemis 2 mission out of Earth orbit and onward to the moon.

The translunar injection burn lasted five minutes and 50 seconds, and committed the spacecraft to a course that will result in a lunar flyby and a gravity-assisted U-turn on April 6. “Looks like a good burn,” capsule communicator Chris Birch said at Mission Control in Houston.

The trajectory is designed so that the capsule, christened Integrity, will return to Earth on April 10 without requiring any further major engine firings. “From this point forward, the laws of orbital mechanics are going to carry our crew to the moon, around the far side and back to Earth,” said Lori Glaze, acting associate administrator for NASA’s Exploration Systems Development Mission Directorate.

After the burn, Canadian astronaut Jeremy Hansen paid tribute to the Artemis team. “We firmly felt the power of your perseverance during every second of that burn,” he told Mission Control. “Humanity has once again shown what we are capable of, and it’s your hopes for the future that carry us now on this journey around the moon.”

Astronauts begin first trip to the moon in decades

After years of postponements and close to $100 billion in spending, NASA has launched the first mission to send astronauts around the moon since Apollo 17 in 1972.

The 10-day Artemis 2 mission began today with the liftoff of NASA’s 322-foot-tall Space Launch System rocket from Launch Complex 39B at Kennedy Space Center in Florida at 6:35 p.m. ET (3:35 p.m. PT). NASA is streaming live coverage of the flight via YouTube and Amazon Prime.

During the last two hours of the countdown, engineers addressed concerns about the rocket’s flight termination system and instrumentation for a battery on the launch abort system. “Godspeed, Artemis 2,” launch director Charlie Blackwell-Thompson told the crew just before liftoff. “Let’s go!”

Artemis 2 is the first crewed test flight in a series leading up to a moon landing that’s currently scheduled for 2028. It follows Artemis 1, which sent a crewless Orion around the moon in 2022. This time, four astronauts are riding inside Orion: NASA mission commander Reid Wiseman, NASA astronauts Christina Koch and Victor Glover, and Canadian astronaut Jeremy Hansen.

“Great view,” Wiseman told Mission Control during the rocket’s ascent. “We have a beautiful moonrise, we’re headed right at it.”

Koch will be the first woman to go beyond Earth orbit. Similar firsts apply to Glover as a Black astronaut, and Hansen as a non-American astronaut.

Although Artemis 2’s astronauts won’t be landing on the lunar surface, they’ll follow a figure-8 trajectory that will send them 4,700 miles beyond the far side of the moon and make them the farthest-flung travelers in human history.

NASA’s most powerful rocket is due to send four astronauts on a round-the-moon journey as early as this week, and although the launch team has to make sure everything goes right in Florida, the mission’s success will also depend on hardware that was built in the Seattle area.

During a visit to two of the contractors for NASA’s Artemis moon program, U.S. Sen. Maria Cantwell said that when it comes to spaceflight, it’s important to get the little things right.

“A lot of people think, ‘Oh, well, we know how to build big rockets,’ right?” the Washington state Democrat said at Karman Space & Defense’s manufacturing facility in Mukilteo, Wash. “But do we know how to separate payloads and return them, and do all of that? That’s what we’re doing here in Puget Sound. … I think that’s the untold story that people don’t understand.”

NASA’s big story will focus on the first humans to go from the Earth to the moon since the Apollo 17 mission in 1972. Artemis 2’s crew won’t land on the lunar surface during what’s expected to be a 10-day mission. But because their figure-8 route takes them 4,700 miles beyond the moon’s far side, they’ll set a new distance record for human travel beyond Earth.

The first opportunity for liftoff from NASA’s Kennedy Space Center in Florida is scheduled for 6:24 p.m. ET (3:24 p.m. PT) on April 1, with backup dates available through April 6. NASA plans to provide live video coverage of the countdown and launch via YouTube, starting at 12:50 p.m. ET (9:50 a.m. PT) on launch day.

This will be the second launch for NASA’s Space Launch System rocket, which sent an uncrewed Orion space capsule around the moon for the Artemis 1 test mission in 2022. The Artemis 2 crew — including NASA astronauts Reid Wiseman, Christina Koch, Victor Glover and Canadian astronaut Jeremy Hansen — will be the first people to ride an Orion into space.

If all goes according to plan, Artemis 2 will clear the way for NASA to test the lunar landers built by Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin space ventures in 2027, then for Artemis 3 to put astronauts on the surface of the moon in 2028. And that’s just the start.

“Ultimately, Artemis is about returning to the moon and building a permanent moon base that can then be used for accelerating our travel to Mars,” Cantwell said.

Bothell, Wash.-based Portal Space Systems has made its first foray into Earth orbit, in the form of a piggyback payload that will test technologies for highly maneuverable space vehicles.

The instrument package, which is about the size of a tissue box, was one of 119 payloads sent into orbit at 4:02 a.m. PT today from Vandenberg Space Force Base in California for SpaceX’s Transporter-16 satellite rideshare mission. Portal’s “Mini-Nova” payload was attached to Momentus’ Vigoride-7 orbital service vehicle for the ride on a SpaceX Falcon 9 rocket.

Minutes after launch, the Falcon 9’s first-stage booster landed autonomously on a drone ship that was stationed in the Pacific. Meanwhile, the second stage proceeded to orbit and deployed Vigoride-7 and other spacecraft.

“I’ve said for a long time that a company only really becomes a space company once it gets to space, and with last night’s launch out of Vandenberg, that’s now true for Portal,” the company’s co-founder and CEO, Jeff Thornburg, said in a LinkedIn post.

NASA pivots to moon base and nuclear Mars mission

NASA’s leaders today laid out an ambitious multibillion-dollar space exploration plan that calls for building a moon base over the next decade and launching a nuclear-powered probe to Mars by 2028.

The space agency is also pressing the pause button on its multibillion-dollar plan to create a moon-orbiting outpost known as the lunar Gateway, and on its plan for transitioning from the International Space Station to commercial outposts in low Earth orbit.

Instead, NASA says it aims to work with commercial partners to procure a government-owned Core Module for the ISS. That module would serve as the attachment point for commercial space modules that could eventually detach to become free-flying space stations.

Meanwhile, the Power and Propulsion Element that was designed for the Gateway would be repurposed for the Mars probe known as Space Reactor-1 Freedom. SR-1 Freedom would be powered by a nuclear electric propulsion system and drop off a payload capable of deploying three helicopters in the Martian atmosphere. Such a mission, known as Skyfall, builds on the success of NASA’s Ingenuity helicopter on Mars and parallels a concept proposed last year by AeroVironment.

NASA is aiming to launch SR-1 Freedom, land astronauts on the lunar surface with its Artemis 4 mission and start laying the groundwork for a moon base with Artemis 5 by the end of 2028, when President Donald Trump’s term in office comes to a close.

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.

NASA’s moon rocket returns to launch pad after tune-up

It took longer than expected, but NASA’s Space Launch System rocket is back on its launch pad in preparation for sending four astronauts on a historic round-the-moon mission as early as next month.

The 322-foot-tall SLS rocket, topped by NASA’s Orion crew capsule, began rolling out from the Vehicle Assembly Building at Kennedy Space Center in Florida at 12:20 a.m. ET March 20 (9:20 p.m. PT March 19). The start of the trip was delayed by more than four hours due to concerns about high winds in the area.

NASA’s rocket and its massive mobile launcher made the 4-mile trek to Launch Complex 39B in 11 hours, traveling at a top speed of less than 1 mph. The trip required the use of a crawler-transporter — the same vehicle used for the Apollo and space shuttle programs, now upgraded for NASA’s Artemis moon program.

The Apollo connection is particularly fitting because this mission, known as Artemis 2, will mark the first time since Apollo 17 in 1972 that astronauts have been sent around the moon. No landing will be made this time around, but the crew is due to go about 4,700 miles beyond the moon’s orbit during their 10-day mission. That would set a new distance record for human spaceflight.
