I’ve nothing against astronauts or scientific innovation. But what’s the point of Artemis II?

It is absolutely self-evident to me that space exploration is pointless, and the more urgent the crises besetting this planet we live on, the more pointless it becomes. I can see why people got excited about it in the 1960s, back when the world was young and we still thought there might be little green...

The astronauts of Artemis II flew further from Earth than any human beings before them, breaking Apollo 13’s distance record at 1.57pm ET on Monday.

Across a six-hour flyby, on the sixth day of a lunar mission that has reinvigorated Nasa’s space exploration programme, the crew of the Orion spacecraft captured views of the moon’s far side that have never been seen before

Both sides don’t want to let their rival dominate. And the competition may yet be transformed further.

The number of human cases of guinea worm, a painful and debilitating tropical illness, fell to a record low of just 10 last year, according to the Carter Centre, the foundation set up by the late former US president Jimmy Carter. But despite years-long declines, it remains almost impossible to completely eradicate the parasite. Only one human illness has been entirely eradicated: smallpox. Why...

Artemis II sets new record as astronauts travel farther from Earth than ever before

On the sixth day of a lunar mission that has rekindled global interest in space exploration and reinvigorated Nasa’s aims to return to the moon, the astronauts of Artemis II flew further...

As the Artemis II mission approaches its lunar flyby, the crew shares an emotional moment as they call mission control to request a previously unnamed moon crater be dedicated to Carroll, the late wife of commander Reid Wiseman. ‘It’s a bright spot on the moon, and we would like to call it Carroll,’ mission specialist Jeremy Hansen says

Four astronauts are set to become Earth’s farthest travelled and exceed a 1970 record on the sixth day of the mission

Artemis II astronauts are on course to set a new distance record Monday when they fly by the moon without stopping there – and then swing around for planet Earth.

The four astronauts – Reid Wiseman, Victor Glover and Christina Koch of the US space agency Nasa; and Canadian...

In today’s newsletter: Far from Earth and out of contact, the four‑person crew ​of Artemis II​ continues a journey designed ​to test​ endurance and the limits of deep‑space exploration

Good morning. For a short period today, the four-person crew of the Artemis II mission will be alone in space, unable to contact anyone on Earth. Facing the far side of the moon, the astronauts will be further...

How to watch the spring constellation defined in ancient Babylon, where it was associated with the god Enlil

Astronauts on Nasa’s Orion capsule made transition about 39,000 miles from the moon, meaning they feel its gravitational pull more strongly than that of the Earth

The four astronauts on Nasa’s Artemis II mission have entered the moon’s “sphere of influence”, where its gravity has a stronger pull on the spacecraft than Earth’s.

The crew made the transition, four days, six hours and two minutes...
