Artemis 2: Four astronauts set for NASA’s first crewed lunar venture in decades

NASA’s Artemis 2 will launch four astronauts aboard the SLS/Orion for a 10-day loop around the Moon, marking the first crewed lunar flight in more than five decades. Following fixes to prior hydrogen leaks and a helium-flow issue, NASA declared go for a Wednesday launch window (6:24 p.m. ET, two hours); a Thursday 7:22 p.m. ET window is the backup. The test flight will validate SLS/Orion operations ahead of a 2028 crewed lunar landing.

Artemis II Preps for First Crewed Moon Mission

NASA outlines live coverage, briefings, and timelines as Artemis II prepares to launch no earlier than April 1 from Kennedy Space Center, sending four astronauts on a roughly 10-day Orion flyaround of the Moon aboard the SLS rocket, with ongoing media events and downlinks through early April and a planned April 10 splashdown.

Artemis II Sets Humans Back on a Moon Flyby Path

NASA’s Artemis II will launch four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—aboard the Space Launch System for a 10‑day, ~600,000‑mile round‑trip lunar flyby, the first crewed Moon visit since Apollo 17. The Orion capsule will perform translunar injection, loop behind the Moon for a 30–50 minute comms blackout, and return to Earth, laying groundwork for Artemis III/IV and a sustained lunar presence while offering rare views of the Moon’s far side, including Orientale and the South Pole–Aitken basin.

Artemis II makes a springtime return to the pad for April launch hopes

Artemis II’s launch vehicle and Orion spacecraft have rolled back to Launch Complex 39B and could launch as early as April 1, with NASA scheduling four two-hour windows from April 1–6 after addressing a helium blockage in the upper stage and past hydrogen-leak issues from the wet dress rehearsal; NASA will not conduct another fueling test, and Artemis planning shifts to using Centaur upper stages for Artemis 4 and 5, with international partners expected at upcoming briefings.

LAVA Simulations Sharpen Artemis II Launch Readiness

NASA used its LAVA CFD tool to model the Artemis II Space Launch System launch environment, showing how water-sound suppression interacts with exhaust plumes and can redirect water to create localized pressure increases; the insights helped refine plume pressures and adapt the launch platform for the crewed mission, with NASA planning to release LAVA to the aerospace community for broader innovation.

Artemis II SLS reaches Pad 39B as FRR clears path for April launch

NASA’s Artemis II stack—the SLS and Orion—reached Launch Pad 39B after a wind-related delay and a plywood mishap during rollout; following a thorough Flight Readiness Review and a fixed helium-seal issue, NASA is set for a No Earlier Than launch opening April 1, with a 10-day lunar mission crewed by Wiseman, Glover, Koch, and Hansen and backup dates through April 6.

Artemis II Moves to Launch Pad for April Moon Flyby

NASA has begun rolling the Space Launch System and Orion back to Launch Pad 39B at Kennedy Space Center for final preparations toward an early-April launch window for Artemis II, a roughly 10-day crewed lunar flyby. After fixes for a helium-flow issue and a liquid-hydrogen leak, the team is aiming to complete tests before liftoff; the crew is quarantined in Houston. If all goes well, Artemis II would be the first crewed lunar mission since the Apollo era.

NASA's SLS rolls to the pad for Artemis 2 launch aimed at April

NASA’s Space Launch System rocket and Orion are rolling from the Vehicle Assembly Building back to Launch Pad 39B for Artemis 2, with liftoff no earlier than April 1 after fixes to a helium-flow issue and other prelaunch work. The crew—Reid Wiseman, Victor Glover, Christina Koch and CSA’s Jeremy Hansen—will orbit the Moon and splash down in the Pacific about 10 days later, marking the first crew aboard Orion. Artemis 2 serves as a precursor to the program’s Moon-landing timeline, which shifts Artemis 4 to host the first lunar landing, while Artemis 3 focuses on Earth-orbit docking tests with a lunar lander; ESA officials emphasized continued international collaboration ahead of upcoming planning discussions.

Artemis II Rolled to Launch Pad Ahead of April Moon Mission

NASA will roll the Artemis II stack—from the Vehicle Assembly Building to Launch Pad 39B at Kennedy Space Center, a roughly four-mile trek that could take up to 12 hours, on March 19 in preparation for an April 1 liftoff (with backup windows through early April and into May). The four-astronaut crew—Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen—will fly a 10-day lunar mission, the first beyond low Earth orbit since Apollo 17 in 1972. Following a hydrogen-leak issue and a prior wet-dress rehearsal, NASA does not plan another WDR for this rollout. Live coverage is available via Space.com and NASA.

Artemis 2 rollout pushed to March 20 after small fix at the pad

NASA will roll the Artemis 2 Space Launch System rocket and Orion crew module back to Launch Complex 39B at Kennedy Space Center on March 20 after a one-day delay caused by a flight termination system electrical harness replacement. NASA still aims for an April 1 liftoff within a window of April 1–6, with astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Jeremy Hansen aboard for a 10-day lunar mission that will help pave the way for Artemis 3 and beyond. The rollout from the Vehicle Assembly Building to the pad is expected to take about 12 hours via the crawler-transporter.

NASA fixes Artemis 2 and targets April crewed lunar flight

NASA says Artemis 2’s Space Launch System rocket has been repaired after a quick-disconnect seal issue on the upper stage. Ground teams completed a design fix, rolled the rocket back to the VAB, and are preparing for a March 19 rollout to Launch Complex 39B with a hopeful launch window around April 1 for a 10-day crewed loop around the Moon aboard Orion, carrying Wiseman, Glover, Koch and Hansen. The flight readiness review confirmed the fix and safety measures; Artemis 3’s plan has shifted to a docking-focused approach with private landers, delaying a lunar landing to Artemis 4/5. If April 1 slips, additional opportunities exist in early April and late April into May.

Artemis II Targets April Launch Window After Thorough FRR

NASA completed the Flight Readiness Review for Artemis II and set an April 1 launch date (target 6:24 p.m. ET) with backup windows on April 2–6 and April 30 for the four-person lunar flyby mission. Officials avoided publishing a precise probabilistic risk number but stressed careful risk mitigation. The review scrutinized the Orion heat shield and propulsion/ground-system issues, including hydrogen leaks and a helium-flow problem that was fixed, with no dissent noted. NASA also decided against another wet dress rehearsal to preserve fuel tanks. The SLS/Orion stack is slated to return to the launch pad by March 19, and the crew joined the FRR virtually from Houston; the mission will last about 10 days and use a lunar flyby path with reentry on Earth.

Artemis 2 targets April Moon mission after repair progress

NASA will host a 3 p.m. EDT briefing to update progress on Artemis 2, the four‑astronaut mission around the Moon using the Space Launch System and Orion. After a fueling test revealed a helium‑flow issue, the rocket stack was rolled back to the Vehicle Assembly Building for repairs; NASA says progress is being made and the next launch window opens in early April (April 1), with live coverage available from Space.com and NASA.

NASA Names Centaur V as SLS Upper Stage, Reshaping Artemis Roadmap

NASA will standardize the Space Launch System upper stage with ULA’s Centaur V for Artemis IV and Artemis V, replacing the ICPS/EUS configuration to allow a faster launch cadence. Artemis 2 remains on track, Artemis 3 is shifted to 2027, and Artemis 4–5 will fly with the Centaur V. The contract was awarded to ULA as a sole-source award, and while Starship/Blue Moon remain potential options for later missions, the current plan centers on the Centaur V-powered SLS.
