The European Space Agency has achieved a European first with Celeste, successfully transmitting a navigation signal from low Earth orbit, following the launch of the mission’s first satellites on March 28. Go to Source The four Artemis II astronauts who looped around the moon this week are expected to splash down soon. NASA’s grand mission spells a return to human deep-space travel, with renewed interest in building a long-term moon base. Go to Source While the Artemis II astronauts have been protected from the icy vacuum of space on their journey, their bodies have nonetheless been left exposed to possibly high levels of radiation—a danger of space travel that NASA is anxiously waiting to study. Go to Source The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data and took in unprecedented moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday’s splashdown. Go to Source On Earth, extreme solar activity often appears as beautiful, benign auroras. But venturing beyond the safety of the Earth’s magnetic field, one faces the full brunt of a temperamental star that can suddenly erupt with flares and coronal mass ejections. Go to Source On April 10, Artemis II—humanity’s first mission to the moon in more than half a century—will draw to a close when the Orion capsule carrying four crew members detaches from its service module. Go to Source Drawing ever closer to Earth, the Artemis II astronauts tidied up their lunar cruiser for its upcoming “fireball” return and reflected on their historic journey around the moon, describing it as surreal and profound. Go to Source Reading the “Mars Trilogy” by Kim Stanley Robinson brings the benefits and pitfalls of efforts to terraform the red planet into sharp relief. Since the 1970s, when Carl Sagan first suggested the possibility that we could make Mars more Earth-like, that process has been a staple of science fiction. But there’s always been a significant […] The closest planet to our sun, Mercury, experiences extreme temperature variations. Since the planet has no atmosphere to speak of, it is in a constant cycle where one side is extremely hot and the other extremely cold. On the sun-facing side, temperatures reach a scorching 427°C (800°F), enough to melt tin and lead, and the […] Artemis II crew will endure 3,000°C on re‑entry. A hypersonics expert explains how they will surviveAfter successfully completing their mission to the moon, the Artemis II crew are about to return to Earth. Go to Source Twin control rooms at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are actively supporting real-time mission operations in lunar orbit as part of the agency’s Artemis II mission, helping ensure astronaut safety and mission success as the crew prepares to return to Earth Friday, April 10. Go to Source The Paranal solar ESPRESSO Telescope (PoET), installed at the European Southern Observatory’s (ESO’s) Paranal site in Chile, has made its first observations. The telescope will work with ESO’s ESPRESSO instrument to study the sun in detail. Described as a solar telescope for planet hunters, PoET aims to understand how the variation in the light from […] They took thousands of photographs and documented copious observations on their voyage around the moon, but as they sped closer to home the Artemis astronauts said Wednesday they have barely started processing the extraordinary experience they shared. Go to Source A week after astronaut Jeremy Hansen blasted off on the historic Artemis II mission to the moon, his wife Catherine recalled the anxiety and thrill of witnessing the journey from afar. Go to Source Lunar love knows no bounds. Now hurtling home from the moon, the Artemis II astronauts took a poignant page from Apollo 8 earlier this week, proposing deeply personal names for a pair of lunar craters. Go to Source |
