Earthrise revisited

The Artemis II mission is heading home after successfully looping around the moon over the Easter weekend. Two days from now, they’ll splash down in the Pacific Ocean, off the coast of San Diego. NASA has been sharing images taken by the four astronauts on board Integrity, the mission’s gumdrop-shaped capsule, as it passed behind the moon. This includes a stunning Earthset and a dramatic solar eclipse (featuring a cameo appearance by several planets).

These images have rekindled the hope and wonder inspired by Apollo 8, the first crewed mission to visit the moon. At the time, much like this week, another Christian festival was underway. It was Christmas Eve 1968. As the Apollo 8 astronauts orbited, they watched the moon’s grey and desolate, crater-pocked surface passing below. Then, something unexpected happened.

The Earth began rising above the horizon. This delicate, blue marble was beguiling. It sat alone in the vastness of space. A fragile, spherical island of life in the inky darkness. Every aspect of the Apollo mission, including a photography timeline, had been planned well in advance. However, nobody anticipated this moment. It caught everyone by surprise.

The Earthrise photos taken by Apollo 8 inspired a generation and kick-started the environmental movement that endures today. Once again, Artemis II captured a similar image, reminding us of our human frailty. Apollo 8 astronaut Jim Lovell talked about a moment in flight when the simple act of raising his thumb in front of him was enough to hide the Earth.

“Everything you’ve ever known is behind your thumb,” he said. “All the world’s problems, everything. It kind of shows you how relative life is and how insignificant we all are here on Earth. Because we are all on a rather small spaceship here.”

 

One American wrote a simple message to the astronauts shortly after their return. “You saved 1968”. It’s all too easy to forget that 53 years ago, America had endured a chaotic and violent year. Martin Luther King Jr. and Robert F. Kennedy had both been assassinated. Race riots had caused many American cities to burn. The Vietnam War was in full swing, and the protest movement against it was growing. Lyndon Johnson had dramatically decided not to seek reelection.

Step forward 53 years, and history seems to be repeating itself. America is embroiled in an increasingly unpopular war. The nation is deeply polarised. A looming threat of recession hangs over the global economy. Once again, our world feels harsh and the future uncertain. Then, a tiny spacecraft circling the moon sends back an image of hope. Once again, we’ve left Earth only to look back and rediscover it anew. This is why I love spaceflight. In its finest hour, it gives us hope for the future.

UPDATE:  11 April 2026

The Artemis crew has just splashed down safely in the Pacific about 100km off the coast of San Diego. Humanity's first flight to the moon in more than 53 years has delivered a textbook landing. The live coverage beaming from space as the Orion capsule entered the atmosphere was extraordinary.  

Incredibly, we watched the capsule separate from its service module live, and then saw the first glow of reentry happen in real time. In an age of AI, the vision was surreal. At times, it honestly looked fake. How sad it is to think that AI is tarnishing the magic of life's momentous events.
