Artemis II captures new 'Earthset' image from lunar orbit
NASA astronauts aboard the Artemis II mission have photographed Earth rising over the Moon's horizon, offering a stark comparison to the famous 1968 Earthrise image that reshaped environmental awareness.
The legacy of Earthrise
During Apollo 8's historic 1968 lunar orbit, astronaut Frank Borman described the Moon's surface as a desolate expanse of gray and black, devoid of color. Then, as the spacecraft rounded the far side, Earth emerged-a vibrant blue-and-white sphere suspended in the void. Crewmate Bill Anders captured the moment, producing an image that became a global symbol of planetary fragility.
"The Earth was the only thing in the entire Universe that had any color. It was a remarkable sight-we're very fortunate to live on this planet," Borman recalled in a 2018 BBC interview.

The Earthrise photo, later credited with inspiring Earth Day in 1970, was taken by chance. NASA had not planned the shot, but its impact was immediate, framing Earth as a delicate oasis amid the lifeless lunar landscape.
A deliberate sequel: Earthset
Nearly six decades later, the Artemis II crew intentionally recreated the moment during their April 6 flyby. The new image, dubbed Earthset, shows Earth partially obscured by the Moon's cratered surface, with Oceania visible beneath swirling clouds. Unlike the 1968 photo, this one was a planned effort, with NASA officials confirming their intent to replicate the iconic shot.
"We're going to do everything we can to make that happen," said Lori Glaze, NASA's Exploration Systems Development Mission Directorate lead, at a post-launch press conference.
Visible changes over 58 years
Though separated by less than a human lifetime, the two images reveal dramatic shifts in Earth's climate and geography. Scientists highlight key differences:
- Atmospheric carbon dioxide levels have risen by a third since 1968, driving global temperatures up by at least 1°C.
- Urban expansion and deforestation have altered land surfaces, replacing dark forests with brighter agricultural zones.
- The Aral Sea, once a vast inland body of water, has shrunk to less than 10% of its 1960s size.
- Antarctica's ice shelves have lost 28,000 km² of area, with the Antarctic Peninsula warming faster than nearly any other region on Earth.
"The cryosphere-Earth's frozen regions-has seen dramatic changes," noted Petra Heil, director of science at the British Antarctic Survey. "Seasonal sea ice cover has decreased in both hemispheres, and snowpacks in North America and Eurasia now melt weeks earlier than in the past."
Human perspective vs. satellite data
While satellites now provide continuous, high-resolution imagery of Earth, the Earthset photo carries unique emotional weight. Craig Donlon of the European Space Agency (ESA) emphasized the difference: "Astronauts make conscious and subconscious choices when framing a shot. That human connection forces us to reflect on our place in the universe."
Sian Proctor, pilot of the civilian Inspiration4 mission, echoed the sentiment: "Apollo 8 changed how we saw our planet. We need that kind of inspiration now more than ever."
Environmental urgency then and now
In 1968, Earth's beauty in the Earthrise photo contrasted sharply with visible environmental degradation. Kathleen Rogers, president of the Earth Day Network, recalled the era's pollution: "You couldn't see across the street in Los Angeles at rush hour, and rivers were literally on fire."
"From space, Earth looks perfect. But as you draw closer, you see the ravages of 150 years of progress. It inspired a generation to step up."

Borman, who passed away in 2023, once remarked that the Apollo 8 crew was more captivated by Earth than the Moon. His words resonate with today's astronauts, who continue to document our changing planet from the vantage point of space.
