The Artemis II mission is more than halfway to the Moon. After cancellation of the first outbound trajectory correction burn, the Artemis II crew began preparing the Orion spacecraft’s cabin for the lunar observation period on Monday, April 6, at…

NASA, Northrop Grumman, and SpaceX are targeting no earlier than 8:49 a.m. EDT on Wednesday, April 8, for the next launch delivering science investigations, supplies, and equipment to the International Space Station. Filled with approximately 11,000 pounds of cargo, the…

NASA’s Artemis II crew in Orion continues on a precise trajectory to flyby the Moon on Monday, April 6. Flight controllers in mission control at NASA’s Johnson Space Center in Houston elected to cancel the spacecraft’s first outbound trajectory correction…

Spacesuit work and eye checks wrapped up the week for the Expedition 74 crew aboard the International Space Station. The orbital residents also focused on robotics, cargo transfers, and science hardware maintenance at the end of the week.

After a successful translunar injection burn on April 2 and a roughly eight-hour crew rest period, the Artemis II crew began their second full day in space, settling into the rhythm of deep‑space operations. Upon burn completion, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen, became the first people to leave Earth’s orbit since the Apollo program in 1972.  The team in…

NASA’s first Artemis II science officers—Kelsey Young, Trevor Graff, and Angela Garcia—are pioneering a new era of mission operations by integrating advanced lunar science directly into Mission Control. Their work will shape how future Artemis crews observe, analyze, and deepen…

Today marks the 100th anniversary of the birth of Virgil I. “Gus” Grissom, born April 3, 1926, in Mitchell, Indiana. As one of NASA’s first seven astronauts, he became America’s second astronaut to fly in space when he launched aboard…

NASA astronaut and Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft’s window after completing the translunar injection burn. There are two auroras (top right and bottom left) and zodiacal light (bottom right) is visible…

Patches of open water in the region contributed to low sea ice extent across the Arctic in March 2026, which tied with the lowest maximum observed in the satellite record.

For the first time in more than 50 years, astronauts on a NASA mission are bound to fly around the Moon after successfully completing a key burn of Orion’s main engine. With the approximately six-minute firing of the spacecraft’s service…

Editor’s Note: Blog updated to reflect update propellant burn quantities. NASA’s Artemis II crew is on the way to the Moon. After the mission management team polled “Go” Thursday, NASA’s Orion spacecraft fired its main engine for five minutes and…

The Expedition 74 crew studied how the brain receives signals in space and demonstrated advanced technology to remove humidity from spacecraft on Thursday. Other activities aboard the International Space Station included servicing a metal 3D printer and continuing to unpack…

NASA’s Artemis II mission management team polled “Go” for the translunar injection burn to send the crew in the Orion spacecraft toward the Moon and send humans around Earth’s closest celestial neighbor for the first time since Apollo 17 in…

NASA’s Space Launch System rocket and Orion spacecraft lift off in this April 1, 2026, image. NASA’s Artemis II mission will take NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy on an…

A view of the Earth from NASA’s Orion spacecraft as it orbits above the planet during the Artemis II test flight. NASA astronauts Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch, and CSA (Canadian Space Agency) astronaut…

Liftoff! NASA’s Artemis II mission launched on April 1, 2026, carrying four Moonbound astronauts. After an approximately 10-day mission, Artemis II ends with a splash. Lili Villarreal, the recovery and landing director for Artemis II, leads the team that will…

The Artemis II crew, working closely with mission control in Houston, were able to restore the Orion spacecraft’s toilet to normal operations following the proximity operations demonstration. Ahead of the apogee raise burn on April 1, the Artemis II crew…

The February 2026 eruption at Piton de la Fournaise has lasted longer and produced a larger volume of lava than recent eruptions from this frequently active volcano.

The Artemis II crew successfully completed the proximity operations demonstration, concluding one of the mission’s early objectives and providing valuable data on how the Orion spacecraft, named Integrity, performs during manual close‑range maneuvering around another spacecraft. Over the course of…

The apogee raise burn was successfully completed, continuing to fine tune the Orion spacecraft’s orbit around Earth. The ICPS (interim cryogenic propulsion stage) ignited its RL10 engine for a precisely timed burn that increased the highest point of the spacecraft’s…

The perigee raise maneuver was successfully completed, refining the Orion spacecraft’s orbit around Earth. The interim cryogenic propulsion stage ignited its RL10 engine for a precisely timed burn that increased the lowest point of the spacecraft’s orbit. Shortly after the…

Spurred by American ingenuity, astronauts on NASA’s Artemis II mission are in flight, preparing for the first crewed lunar flyby in more than 50 years. NASA’s SLS (Space Launch System) rocket lifted off from Launch Pad 39B at the agency’s…
