This image from April 10, 2026, captures NASA’s Orion spacecraft, with its parachutes deployed, seconds before splashdown in the Pacific Ocean. The Artemis II crew accomplished many milestones on their nearly 10-day mission, surpassing the Apollo 13 record for farthest crewed spaceflight and capturing views of the far side of the Moon.

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

NASA Welcomes Record-Setting Artemis II Moonfarers Back to Earth 

NASA Welcomes Record-Setting Artemis II Moonfarers Back to Earth 

NASA’s Orion spacecraft with Artemis II crewmembers NASA astronauts Reid Wiseman, commander; Victor Glover, pilot; Christina Koch, mission specialist; and CSA (Canadian Space Agency) astronaut Jeremy Hansen, mission specialist aboard was seen as it splashed down at 5:07 p.m. PDT in the Pacific Ocean off the coast of California, Friday, April 10, 2026.

The first astronauts to travel to the Moon in more than half a century are back on Earth after a record-setting mission aboard NASA’s Artemis II test flight.

NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen splashed down at 5:07 p.m. PDT Friday off the coast of San Diego, completing a nearly 10-day journey that took them 252,756 miles from home at their farthest distance from Earth.

“Reid, Victor, Christina, and Jeremy, welcome home, and congratulations on a truly historic achievement. NASA is grateful to President Donald Trump and partners in Congress for providing the mandate and resources that made this mission and the future of Artemis possible,” said NASA Administrator Jared Isaacman. “Artemis II demonstrated extraordinary skill, courage, and dedication as the crew pushed Orion, SLS (Space Launch System), and human exploration farther than ever before. As the first astronauts to fly this rocket and spacecraft, the crew accepted significant risk in service of the knowledge gained and the future we are determined to build. NASA also acknowledges the contributions of the entire NASA workforce, along with our international partners, whose expertise and commitment were essential to this mission’s success. With Artemis II complete, focus now turns confidently toward assembling Artemis III and preparing to return to the lunar surface, build the base, and never give up the Moon again.”

After splashdown in the Pacific Ocean, the astronauts were met by a combined NASA and U.S. military team that assisted them out of the spacecraft in open water and transported them via helicopter to the USS John P. Murtha for initial medical checkouts. The crew members are expected to return to NASA’s Johnson Space Center in Houston on Saturday, April 11.

During their mission, Wiseman, Glover, Koch, and Hansen flew 694,481 miles in total. Their lunar flyby took them farther than any humans have ever traveled before, surpassing the previous distance record set by Apollo 13 astronauts in 1970.

The first Artemis crew launched on NASA’s SLS rocket at 6:35 p.m. April 1, from Launch Pad 39B at the agency’s Kennedy Space Center in Florida. With 8.8 million pounds of thrust at liftoff, the American-built rocket propelled the crew inside the Orion spacecraft to space, delivering it to orbit with pinpoint accuracy after a smooth countdown conducted by the agency’s Artemis launch control team.

During the first day in space, the astronauts and teams on the ground checked out the spacecraft — named Integrity by the crew — to confirm all systems were healthy ahead of the transit to the Moon. NASA also deployed four CubeSats from international partners to Earth orbit.

On the second day of the test flight, with all systems Go, Orion’s service module fired its main engine, placing the astronauts on a trajectory that brought them 4,067 miles above the lunar surface at their closest approach.

“The Artemis II crew is home. The entry, descent, and landing systems performed as designed and the final test was completed as intended. This moment belongs to the thousands of people across fourteen countries who built, tested, and trusted this vehicle. Their work protected four human lives traveling at 25,000 miles per hour and brought them safely back to Earth,” said NASA Associate Administrator Amit Kshatriya. “Artemis II proved the vehicle, the teams, the architecture, and the international partnership that will return humanity to the lunar surface. Reid, Victor, Christina, and Jeremy carried the hopes of this world farther than humans have traveled in more than half a century. Fifty‑three years ago, humanity left the Moon. This time, we returned to stay. The future is ours to win.”

With astronauts aboard for the first time, engineers put Orion through a full in‑flight evaluation. The crew tested the spacecraft’s life support systems, confirming Orion can sustain humans in deep space. During several piloting demonstrations, crew members took manual control of the spacecraft, flying Orion to validate its handling and collect data that will guide future rendezvous and docking operations with human-rated landers during Artemis III and beyond.

The crew completed a series of tests to inform how NASA will fly future missions to the Moon, including evaluations of how the spacecraft operates during crew exercise, emergency equipment and procedures, the Orion crew survival system spacesuits, and other critical spacecraft systems.

Wiseman, Glover, Koch, and Hansen also supported scientific investigations to help NASA prepare astronauts to live and work on the Moon as the agency builds a Moon Base and looks toward Mars. These experiments — including the AVATAR investigation, which studies how human tissue responds to microgravity and the deep space radiation environment, and other human research performance studies — are gathering essential health data for long-duration missions.

During their April 6 lunar flyby, the astronauts captured more than 7,000 images of the lunar surface and a solar eclipse, during which the Moon blocked the Sun from Orion’s vantage point. The imagery includes striking views of earthset and earthrise, impact craters, ancient lava flows, our Milky Way galaxy, and surface fractures and color variations across the lunar terrain.

They documented the topography along the terminator — the boundary between lunar day and night — where low-angle sunlight casts long shadows across the surface, creating illumination conditions similar to those in the South Pole region where astronauts are scheduled to land in 2028. The crew also proposed potential names for two lunar craters and reported meteoroid impact flashes on the night side of the Moon.

Artemis II science will pave the way for future missions to the Moon’s surface by helping advance mission operations and training astronauts to use well-informed judgment to identify areas of high interest for science and exploration.

With the crew safely on Earth, NASA and its partners now will turn attention to preparing for next year’s Artemis III mission, when a new Orion crew will test integrated operations with commercially built Moon landers in low Earth orbit.

As part of a Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly challenging missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and lay the groundwork for sending the first astronauts – American astronauts –  to Mars.

Northrop Grumman’s Cygnus XL cargo spacecraft sits atop a SpaceX Falcon 9 rocket counting down to a launch targeted at 7:41 a.m. EDT on Saturday to resupply the Expedition 74 crew. Packed with over 11,000 pounds of lab hardware, science experiments, and crew supplies, Cygnus XL is due to arrive at the International Space Station where it will be captured with the Candarm2 robotic arm on Monday.

NASA flight engineers Chris Williams and Jack Hathaway joined each other in the cupola on Friday and practiced capturing Cygnus XL during a computer simulation using the robotics workstation. Williams and Hathaway trained to use the workstation’s control panel and hand controllers to maneuver the Canadarm2. The duo watched camera views simulating the Cygnus XL approaching the station and prepared for different capture scenarios.

Williams will be at the controls of the robotics workstation on Monday maneuvering the Canadarm2 to capture Cygnus XL while Hathaway monitors the spacecraft’s approach and rendezvous. Following its capture, mission controllers will take over and remotely command the Canadarm2 to install Cygnus XL to the Unity module’s Earth-facing port where it will stay for a six-month mission.

Watch the agency’s Cygnus XL launch and arrival coverage on NASA+Amazon Prime, and the agency’s YouTube channel. Learn how to watch NASA content through a variety of platforms, including social media.

Afterward, Williams and Hathaway gathered together with flight engineers Jessica Meir of NASA and Sophie Adenot of ESA (European Space Agency) and called down to mission controllers to discuss cargo operations after the hatches are opened on Cygnus XL. Inside the resupply ship will be a host of new science experiments including a quantum physics module to expand the abilities of the Cold Atom Lab,  a blood stem cell study to treat cancers and blood disorders, an investigation to protect astronaut gut health, and more.

In the Roscosmos segment of the orbital outpost, station commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev took turns wearing an acoustic sensor around their necks and recorded their rapid exhalation to understand how microgravity affects the respiratory system. Flight engineer Andrey Fedyaev continued testing artificial intelligence tools to improve space crew operations and communications.

This image, taken from behind the Moon, shows its half-illuminated surface in sharp detail. To the right, a much smaller crescent Earth can be seen, with shades of blue and white just barely distinguishable. A faint reflection of the Orion spacecraft's window overlays the scene, especially in its right half.
NASA

Seen during Artemis II’s lunar flyby on April 6, 2026, the Moon and Earth align in the same frame, each partially illuminated by the Sun. The Moon’s surface appears in sharp detail in the foreground, while Earth sits much farther away, smaller and softly lit in the background. A faint reflection in the spacecraft window is also visible, subtly overlaying the scene. Though their phases differ, both are shaped by the same sunlight, revealing the geometry of the Sun–Earth–Moon system from deep space.

NASA astronauts Reid Wiseman, Christina Koch, and Victor Glover, and CSA (Canadian Space Agency) astronaut Jeremy Hansen are set to return to Earth, splashing down in the Pacific Ocean around 8:07 p.m. EDT. Watch their return with NASA.
