Jeff Bezos' Blue Origin is assessing damage to its Florida launch pad after a rocket exploded during a test firing. The company fueled the massive New Glenn rocket Thursday night, hoping to briefly ignite the engines ahead of a satellite launch next week. But the 321-foot rocket blew up, taking part of the pad with it. Emergency officials are warning the public to avoid any wreckage that might wash ashore and instead call 911. New Glenn is the rocket that Blue Origin plans to use to launch landers to the moon for NASA.

The Artemis II astronauts are tidying up their lunar cruiser for Friday's "fireball" return to Earth. They're also reflecting on their historic journey around the moon, describing it as surreal and profound. The three Americans and one Canadian are now under 150,000 miles from home. Humanity's first lunar explorers in more than a half-century, they set a new distance record during Monday's lunar flyby. Artemis II is aiming for a splashdown in the Pacific off the San Diego coast.

The Artemis II astronauts have captured Earth's brilliant blue beauty as they zoom ever closer to the moon. NASA released the crew's first downlinked images Friday, 1 1/2 days into the first astronaut moonshot in more than half a century. The first photo taken by commander Reid Wiseman shows a curved slice of Earth in one of the capsule's windows. The second shows the entire globe with the oceans topped by swirling white tendrils of clouds. It even includes a pale green aurora. As of midday Friday, the crew was 100,000 miles from Earth and quickly gaining on the moon.

The replacements for the astronauts involved in NASA's first medical evacuation are on their way to the International Space Station. SpaceX launched the fresh crew on Friday from Florida. The four astronauts are representing the U.S., France and Russia and should reach the orbiting lab Saturday. They'll fill the vacancies left by their evacuated colleagues. NASA had to put spacewalks on hold and defer other duties after an unidentified astronaut experienced a serious medical issue in January. The entire crew returned to Earth more than a month early, leaving three astronauts in orbit.

Four astronauts are on their way to the International Space Station after being sidelined by Boeing's Starliner trouble and other issues. SpaceX launched the U.S.-Japanese-Russian crew from Florida on Friday. They should reach the space station this weekend, replacing colleagues who launched in March as fill-ins for NASA's two stuck astronauts. Leading the taxi flight for NASA is Zena Cardman. She was yanked from a SpaceX flight last year to make room for Starliner's test pilots whose capsule was judged too dangerous to fly. Two of her crewmates were also training on Starliner, which remains grounded until next year.

A SpaceX rocket being tested in Texas has exploded, sending a dramatic fireball high into the sky. The company says the Starship "experienced a major anomaly" at about 11 p.m. Wednesday while on the test stand at Starbase, SpaceX's launch site at the southern tip of Texas. The company says in a statement on X that "all personnel are safe and accounted for." SpaceX says there are no hazards to nearby communities. It has asked people not to try to approach the site. It marked the latest in a string of incidents this year involving the massive rockets.

Elon Musk is dialing back his threat to decommission a capsule used to take astronauts and supplies to the International Space Station for NASA. The threat came as President Donald Trump and Musk argued on social media on Thursday. Trump said he could cut government contracts given to Musk's rocket company, SpaceX. Musk responded by saying SpaceX will begin decommissioning its Dragon spacecraft. It was unclear how serious he was, but he later posted he wouldn't withdraw the capsule. SpaceX is the only U.S. company capable right now of transporting crews to and from the space station, using its four-person Dragon capsules.

On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first human in space, orbiting the earth once before landing safely via parachute after a planned ejection from his space capsule.

On an episode of "The Story Behind the AP Story," Associated Press space writer Marcia Dunn discusses the space odyssey of NASA's two stuck astronauts. Butch Wilmore and Suni Williams are finally on their way home after more than nine months in space. Wilmore and Williams left the International Space Station in a SpaceX capsule early Tuesday, checking out with two others. The capsule is due to splash down in the evening off the Florida coast, weather permitting. The astronauts will then be taken to Houston. The astronauts' return will close out a dramatic marathon mission that began with a bungled test flight of Boeing's Starliner capsule last June.

Four astronauts are back on Earth after a space station mission that lasted almost eight months. A SpaceX capsule carrying the crew parachuted into the Gulf of Mexico off the Florida coast before dawn Friday. The three Americans and one Russian should have returned from the International Space Station two months ago, but were delayed by Boeing's Starliner crew capsule and weather. Shortly after splashdown, NASA said one of its astronauts had a medical issue. The space agency says the unidentified astronaut is in stable condition and remains at a Florida hospital as a "precautionary measure."
