On Monday, Artemis II traveled farther from Earth than any human has gone before. As the Orion capsule performed a historic flyby of the moon’s far side, the four crew members — Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen — became the first people to see some regions of the moon’s far side with their own eyes. CBS News interviewed several former NASA astronauts to weigh in on what the mission revealed and what it means for the future of lunar exploration.
Overview effect, color and context
– James Hansen Newman, a physicist and former shuttle astronaut, said the images and the crew’s experience show the “overview effect” — how seeing Earth and the moon from that vantage point changes perceptions. He emphasized the power of human eyes and firsthand observations compared with photos, saying the naked-eye experience conveys something that pictures cannot fully capture.
– Retired astronaut Terry Virts, who spent more than seven months in space, was struck by the color variations on the lunar surface. He and Apollo-era astronauts have described the moon as less monotonous than often assumed: up close there are browns, greens and different surface materials. Virts also highlighted how today’s high-definition cameras render images differently than Apollo-era footage, and he called the mission deeply emotional, noting tributes and personal touches the crew included.
What the images showed
– The crew sent photos showing Earthset views, the darkness of a solar eclipse seen from space, detailed terrain on the far side and previously unknown craters. Former astronauts pointed out the scientific and human value of those images and of the crew’s audible, in-the-moment observations describing textures, colors and roughness along the terminator (the line between lunar day and night).
– Observers stressed that while robotic missions have mapped much of the moon, human perception — depth, color, and nuances of light and shadow — provides complementary insights and inspiration.
Operations, communications and the far-side blackout
– Artemis II inevitably passed behind the moon, temporarily losing radio contact with Earth. Bill Harwood, CBS News space consultant, noted that going out of contact behind the moon is expected for lunar flybys and did not add new risk; regaining contact is always a welcome milestone. The flight’s primary goal remains a systems test of Orion — life support and spacecraft performance — before future operational lunar missions.
– The crew’s call sign “Integrity” was heard when they came back into the line-of-sight; the moment underscored the routine nature of the planned communications blackout and the reliability of Newtonian orbital mechanics for returning signals.
Tributes and naming a feature
– The crew made an emotional on-board dedication: they informally suggested naming a visible lunar feature “Carroll” to honor a family member of one of the crew. Bill Harwood explained that while the International Astronomical Union (IAU) formally approves planetary feature names, informal naming by crews during missions continues an Apollo-era tradition and has powerful meaning for families and the astronaut community.
Comparisons to Apollo and historical perspective
– MIT professor and former astronaut Jeffrey Hoffman compared the flyby to Apollo 8 in symbolic terms: both missions occurred in difficult times and provided a unifying and hopeful human achievement. Hoffman noted a critical difference: Artemis II did not enter lunar orbit because Orion and its propulsion profile are configured for flyby rather than insertion — the mission is not an Apollo-style orbit insertion but a crewed test that extends human reach beyond low Earth orbit.
– Several former astronauts said Artemis II’s success marks a return to crewed lunar operations and a stepping stone toward sustained lunar presence and eventual missions to Mars.
Human contributions vs. robotic and telescopic data
– Multiple speakers — including Dottie Metcalf-Lindenburger, Cady Coleman and Terry Virts — stressed the complementary roles of humans and robots. Robotic and orbital telescopes (such as Webb) deliver high-value data about the universe and distant locales, but humans in the lunar vicinity add unique situational judgment, observational richness and emotional resonance that benefit science, exploration planning and public engagement.
– The astronauts aboard Artemis II provided naked-eye descriptions that will inform future observations and science planning because human vision registers colors, contrasts and three-dimensional cues that current cameras and image processing do not fully reproduce.
Mission next steps and splashdown
– After completing the lunar flyby, Orion was scheduled to return to Earth and splash down Friday evening in the Pacific off San Diego, with recovery operations detailed: a recovery ship, helicopters and boats to retrieve the crew, initial medical checks on board, then transfer to a Naval Station in San Diego and return to NASA facilities in Texas.
– Flight teams planned routine pre‑reentry procedures: configuring the spacecraft, checking suits and life-support hardware, resting the crew and preparing for atmospheric entry — a high-risk phase in any deep-space mission. Retired astronauts watching the mission emphasized confidence in engineers and mission control while acknowledging that reentry and heat‑shield performance are areas to watch closely.
What this means for Artemis and beyond
– The mission is part of a relay of Artemis flights: Artemis II demonstrates human operation of Orion beyond low Earth orbit and informs Artemis III preparations, which aim to land humans on the moon again. Several former astronauts said the success of Artemis II makes the overall program more likely to proceed with sustained lunar operations, citing an institutional momentum at NASA and increasing commercial participation.
– Among the broader takeaways: the emotional effect of seeing Earth and the far side of the moon continues to inspire. Those who flew in the shuttle, the ISS or Apollo-era missions recalled being moved by the unique perspective and voiced optimism that Artemis will catalyze scientific discovery, international cooperation and long-term exploration plans, including preparing for Mars.
Voices on the mission
– James Hansen Newman (former shuttle astronaut, space-systems professor) highlighted the overview effect and the mission’s cultural significance.
– Terry Virts (retired astronaut) described emotional reactions to the imagery and the differences between human vision and camera capture.
– Jeffrey Hoffman (MIT professor, former astronaut) placed the flight in historical context relative to Apollo.
– Bill Harwood and CBS News contributors provided operational and technical highlights.
– Dottie Metcalf-Lindenburger, Cady Coleman, Bonnie Dunbar, Terry Hart and other retired astronauts praised the mission’s success and emphasized the human element in exploration.
Artemis II’s flyby extended human presence and perspective, produced striking imagery and firsthand observations of lunar far‑side terrain, and delivered a meaningful test of Orion’s systems — a major step on the path toward returning humans to the lunar surface and establishing a long-term presence in cislunar space.
