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.

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.

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.

Scientists find evidence of faraway worlds colliding

Astronomers say unusual readings from a star system 11,000 light-years away suggest that two of the planets circling the star crashed into each other, creating a huge, light-obscuring cloud of rocks and dust.

The analysis, laid out this week in a paper published by The Astrophysical Journal Letters, could provide new insights into the occasionally cataclysmic process that governs the evolution of planetary objects — including our own planet Earth and its moon.

“There are only a few other planetary collisions of any kind on record, and none that bear so many similarities to the impact that created the Earth and moon,” University of Washington graduate student Anastasios Tzanidakis, the study’s lead author, said in a news release. “If we can observe more moments like this elsewhere in the galaxy, it will teach us lots about the formation of our world.”

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.

NASA rolled the giant rocket that’s slated to launch four astronauts on a round-the-moon trip back to its garage today to troubleshoot a problem with its helium pressurization system.

The Space Launch System rocket, topped by an Orion crew capsule, returned to the 52-story Vehicle Assembly Building at Kennedy Space Center in Florida at about 8 p.m. ET (5 p.m. PT), NASA said. It took more than 10 hours for NASA’s crawler-transporter to make the 4-mile trip from Launch Complex 39B.

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.”

Occupy Mars? Or the moon? It’s time for a reality check

It’s an age-old debate in space circles: Should humanity’s first city on another world be built on the moon, or on Mars?

As recently as last year, SpaceX founder Elon Musk saw missions to the moon as a “distraction.” In a post to his X social-media platform, he declared that “we’re going straight to Mars.”

But last week, Musk said he’s changed his mind: “For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years,” he wrote on X.

How realistic is either option, particularly on a 10- to 20-year time frame? In a new book titled “Becoming Martian,” Rice University evolutionary biologist Scott Solomon lays out the possibilities as well as the perils that could make Musk’s job more challenging than he thinks.

“The more research I did on this topic, and the more labs I visited, and papers I read, and experts I spoke with, what became clear to me is that we have some pretty big gaps in our knowledge, in our understanding of what the reality would be like,” Solomon says in the latest episode of the Fiction Science podcast.
