The Artemis II crew has crossed the halfway mark on its journey to the moon, with NASA releasing new imagery Saturday morning on X as the four astronauts prepare for a historic flyaround that will take them farther from Earth than any human has traveled in more than half a century.

NASA's Artemis II mission completes a critical engine burn, propelling the Orion spacecraft and its four-person crew out of Earth orbit toward the moon.

NASA proposed a new solution that would bind the private companies more closely to NASA, requiring them not to build free-flying space stations but rather to work directly with the space agency on modules that would, at least initially, dock with the International Space Station. This change was not well-received.

While a new milestone for NASA, the Artemis II mission won’t break the record for the farthest that a human-rated spacecraft has ever traveled into space: In 2022, the same Orion module — with no astronauts aboard — had traveled 268,563 miles from Earth during an uncrewed Artemis I test mission around the moon.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will unveil a look at the agency’s Nancy Grace Roman Space Telescope.

When a reactor’s radioactive core undergoes nuclear fission, its atoms split and release heat, which then turns the water to steam. That steam rushes through the machine at high pressure, spinning turbines to generate electricity destined for the grid, according to the association. In space, the process gets trickier.

NASA launched the Artemis II mission, which will carry humans to the moon for the first time since 1972.

The U.S. space agency launched a lunar flyby Wednesday, but Beijing is pursuing its own space program with formidable focus. Here’s what we know about it, in photos and videos.
