Astronomers using NASA’s James Webb Space Telescope have produced the most detailed map yet of the universe’s cosmic web, the vast network of dark matter and gas that links galaxies. The map traces structures back to when the universe was roughly one billion years old.

Thales Alenia Space has acknowledged a manufacturing issue affecting habitation modules for NASA's former Lunar Gateway project.

NASA Administrator Jared Isaacman told lawmakers that SpaceX and Blue Origin expect their lunar landers to be ready for the Artemis III mission in late 2027. The mission will now test the landers in Earth orbit rather than attempting a lunar landing. This change aims to reduce risks and increase launch frequency.

Orion spacecraft from Artemis 2 mission has completed its final maneuver before atmospheric reentry, the most critical phase of the journey. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen face a 13-minute descent at over 40,000 km/h and temperatures above 2,500 degrees, with splashdown planned off San Diego.

NASA's Artemis II mission, the first crewed flight of the Orion spacecraft around the Moon since 1972, has encountered a helium leak in its service module but officials say it poses no threat to the crew's return. The spacecraft, carrying astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, launched on April 1 and is set for splashdown in the Pacific Ocean on Friday evening. Ground teams adjusted the flight plan to study the leak while maintaining nominal performance.
