NASA Captures First-Ever 'Earthset' Photo from Far Side of the Moon Amid Artemis II Mission
NASA released the first-ever photograph of Earth from the far side of the moon, dubbed 'Earthset,' during the Artemis II lunar flyby. The historic image, reminiscent of the 1968 'Earthrise' photo, was captured by astronauts aboard the Orion spacecraft as Earth appeared to set behind the lunar horizo
Artemis 2 Astronauts Set Distance Record in Historic Lunar Flyby Beyond Earth Orbit
NASA’s Artemis 2 crew has shattered a 54-year-old human spaceflight record, venturing farther from Earth than any astronauts in history during a groundbreaking lunar flyby. The mission marked the first crewed trip beyond low Earth orbit since 1972, paving the way for future lunar exploration.
Artemis II Crew Honors Late Astronaut's Wife with Moon Crater Name
The Artemis II crew will name a lunar crater 'Carroll' after Reid Wiseman's late wife, honoring her legacy while making history 240,000 miles from Earth. NASA's decision reflects a personal tribute amid humanity's first crewed moon mission in over 50 years.
Astronomers Uncover Vast Hydrogen Gas Halos Fueling Early Universe Galaxies During 'Cosmic Noon'
The HETDEX study has identified 33,000 Lyman-alpha nebulae, hydrogen gas halos surrounding early galaxies 10-12 billion years ago. This tenfold increase reveals critical fuel sources for star formation during Cosmic Noon.
NASA's Artemis 2 Moon Mission Faces Critical Space Toilet Malfunctions, Burning Odor Reported
NASA's Artemis 2 crew encountered multiple failures in the new Universal Waste Management System (UWMS) toilet, including a burning odor in the hygiene bay. The issues required urgent intervention from ground control to restore limited functionality.
How Human Evolution Crafted Survival in Extreme Environments: From Choking Risks to Oceanic Depths
Humans evolved unique adaptations to survive in extreme environments, from a low larynx enabling speech to genes from ancient hominins like Denisovans. These traits highlight evolution's trade-offs, including choking risks, altitude sickness, and enhanced diving abilities.
Artemis II Crew to Surpass Apollo 13’s Record on Monday’s Lunar Flyby: What’s at Stake and What’s Next
NASA’s Artemis II crew will break Apollo 13’s 1970 distance record during Monday’s lunar flyby, venturing 4,100 miles farther than the famed mission. The six-hour maneuver will offer unprecedented views of the moon’s far side and a rare solar eclipse from space.
NASA Halts Work on SLS Mobile Launcher 2, Reallocates Resources for Artemis Mission Upgrades
NASA has issued a stop-work order on Mobile Launcher 2, the $383 million platform meant for the canceled SLS Block 1B rocket. The agency is repurposing hardware to support ongoing Artemis missions amid cost overruns that ballooned to $2.5 billion.
How NASA's Artemis II Toilet System Highlights Deep Space Life Support Challenges
NASA’s Artemis II mission is exceeding expectations, but a recent focus on Orion’s toilet system—including frozen urine—underscores the critical role of life support in deep space.
