The Artemis 2 crew spent seven hours observing the Moon on April 6 — here’s what they noticed.

Yesterday, the four-person Artemis 2 crew accomplished the primary crewed lunar flyby since Apollo 17 in 1972, passing inside roughly 4,067 miles of the lunar floor earlier than turning again towards Earth.
The seven-hour statement window started as Orion crossed into the Moon’s gravitational sphere of affect late Sunday and ended with one of the dramatic views any astronaut has ever witnessed.
Because the spacecraft swept behind the Moon, the crew photographed the lunar farside — its affect craters, historic lava flows, and floor ridges — terrain no human eye had seen from this shut in over half a century. As Orion emerged, the Moon, Solar, and spacecraft aligned completely. The crew skilled practically an hour of photo voltaic eclipse totality, throughout which they imaged the corona and scanned the darkened lunar floor, recognizing a number of meteoroid affect flashes glowing towards the Moon’s earthshine-lit floor.
Listed below are probably the most compelling photographs from humanity’s closest take a look at the Moon in additional than half a century.

Through the seven-hour lunar flyby, the Artemis 2 crew rotated by positions and tasks in shifts, guaranteeing contemporary eyes on the home windows always and a gentle stream of photographs, video, and recorded observations all through the statement window. Again at Mission Management, the mission’s scientists gathered to advise and seek the advice of, aiming for the crew’s information to immediately inform the way forward for lunar analysis. Right here, Commander Reid Wiseman takes his place on the window simply as his first statement interval begins, the Moon filling the view past. Wiseman and his crew have been skilled to doc terrain options, observe variations in shade, brightness, and texture, and describe what they noticed in actual time for the science group on the bottom. Credit score: NASAThe lunar statement interval started at 2:45 p.m. EDT, and inside hours, the crew was already delivering the real-time science NASA had hoped for. At 3:41 p.m. EDT, they captured this placing view of the Orientale basin — one of many Moon’s youngest and best-preserved giant affect craters. On to the northwest are two smaller craters that the crew has proposed naming Integrity and Carroll. Carroll is a tribute to the late spouse of Commander Reid Wiseman. The photographs and recordings from the flyby will assist scientists refine fashions of crater formation and higher perceive the Moon’s geologic historical past. Credit score: NASAAt 6:41 p.m. EDT — simply three minutes earlier than Integrity slipped behind the Moon and misplaced contact with Earth for 40 minutes — the crew captured this Earthset, the second Earth drops under the lunar horizon. Within the foreground, Ohm crater is seen, the signature of a large historic affect. Within the background, {a partially} darkened Earth disappears behind the lunar edge, its day aspect revealing clouds over Australia and Oceania.One other angle on Earthset, shot by the Integrity window. Earth sinks additional behind the lunar terrain under. Credit score: NASAAt 7:22 p.m. EDT — simply 41 minutes after Earthset — the crew witnessed Earthrise. Orion had spent 40 minutes sweeping silently throughout the lunar farside, fully out of contact with the bottom, earlier than Earth crept again into view on the opposite aspect. Shot with a 400mm lens, it seems as a fragile crescent, solely its higher edge catching daylight, cloud programs faintly seen alongside the illuminated arc. Credit score: NASASecurity is paramount when viewing an eclipse — even from the Moon. As Orion swept across the Moon, the spacecraft, Moon, and Solar aligned completely, plunging the crew into the Moon’s shadow and producing a complete photo voltaic eclipse in contrast to any seen on Earth. From their vantage level, the Moon appeared 5 instances bigger than the Solar. The crew reached for eclipse glasses that may look acquainted to anybody who has seen an eclipse again dwelling. The crew solely wanted the glasses because the Solar slipped behind and reemerged from behind the lunar limb — throughout totality itself, the Moon blocked the Solar solely. Credit score: NASAThe crew skilled practically an hour of totality that exposed stars usually hidden by the Moon’s shine. Earthshine — daylight bouncing off Earth and again onto the Moon — faintly illuminated the darkened lunar floor whereas the photo voltaic corona appeared as a faint, fuzzy halo on the edge. Credit score: NASAThis eclipse picture, taken from Integrity, reveals off a tighter crop of totality. The Moon’s disk extends past the body because it blocks the Solar solely. The corona seems as a mushy halo across the lunar edge. At left, a shiny pinpoint of sunshine is Venus. Alongside the Moon’s horizon, earthshine — daylight mirrored off Earth — faintly illuminates Mare Crisium, a darkish volcanic plain seen from Earth with the bare eye. Credit score: NASAThe eclipse attracts to a detailed. After practically an hour of totality, daylight begins creeping again across the lunar edge — a shiny sliver breaking the darkness because the Solar and Moon slide out of alignment. At this level, Integrity had begun its journey dwelling. Credit score: NASA
