Artemis II detects helium leak but proceeds to safe reentry

April 10, 2026 由 AI 报道 AI 生成的图像

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.

Hubble captures giant chaotic planet-forming disk

NASA's Hubble Space Telescope has imaged the largest known protoplanetary disk, revealing a turbulent and asymmetric structure around a young star. The disk, nicknamed Dracula's Chivito, stretches nearly 400 billion miles across and lies about 1,000 light-years from Earth.

James Webb telescope reveals clearest map of cosmic web

May 12, 2026 由 AI 报道

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.

NASA sets Artemis III for late 2027 Earth orbit tests

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.

NASA releases initial Artemis II mission assessments

April 25, 2026 由 AI 报道

NASA has completed initial evaluations of the Artemis II mission systems following the crew's safe return from a lunar flyby earlier this month. The Orion spacecraft and SLS rocket performed as expected, setting a new record for the farthest distance traveled from Earth. Minor issues arose with the toilet system, but the crew resolved them successfully.

JWST uncovers metal-poor atmosphere on exoplanet TOI-5205 b

Astronomers using the James Webb Space Telescope have detected an unusually metal-poor atmosphere on the Jupiter-sized exoplanet TOI-5205 b, which orbits a small, cool star. The planet's atmospheric metallicity is lower than that of its host star, challenging theories of giant planet formation. The findings come from a study led by researchers at NASA's Goddard Space Flight Center and Carnegie Science.

Artemis II astronauts use iPhones to snap lunar photos

April 07, 2026 由 AI 报道

Astronauts aboard NASA's Artemis II mission captured striking images of the Moon and Earth using iPhone 17 Pro Max smartphones during their recent lunar flyby. The crew, including Commander Reid Wiseman and Mission Specialist Jeremy Hansen, also employed Nikon cameras for high-resolution shots now being released by NASA. The mission, which launched on April 1, reached a record distance from Earth and is set to splash down off California this week.
