Nasa has selected the four astronauts who will fly to the Moon under the Artemis II mission, a critical step toward re-establishing a human presence on the lunar surface. The crew includes Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian astronaut Jeremy Hansen. The mission, scheduled for late 2024, will send them around the Moon and back, laying the groundwork for a landing on Artemis III.
But the hardware that will make that landing possible is being assembled in Britain. The lander, known as the International Habitation Module (IHM), is a collaborative project led by the UK Space Agency. It is designed to ferry astronauts from lunar orbit to the surface and back. The module’s life support systems, propulsion, and rugged landing gear will be tested for the first time during the uncrewed Artemis II flight.
From a physical reality perspective, this is not a small achievement. The IHM must survive the violent vibrations of launch, the vacuum of space, and the abrasive lunar dust. British engineers at Airbus Defence and Space in Stevenage have spent years refining the heat shield and landing sensors. The module’s fuel cells, which combine hydrogen and oxygen to produce electricity and water, are a direct line to the Apollo era but with modern efficiency.
The significance of Artemis II is dual: it re-establishes crewed lunar operations and validates the UK’s role as a critical partner in deep space exploration. For decades, British contributions to space science have been limited to satellite payloads and robotic probes. Now, the nation is building the actual vehicle that will set human boots on another world.
But I must temper the excitement with a sobering data point. Each launch of the Space Launch System (SLS) costs approximately $4.1 billion. That is more than the entire annual budget of Nasa’s Earth Science Division, which monitors our rapidly warming planet. The carbon footprint of a single SLS launch is estimated at 3,000 tonnes of CO2 equivalent, roughly equal to 600 homes for a year. As we race to explore the cosmos, we must also ask whether those resources could be better spent on the biosphere collapse unfolding below.
Nevertheless, the programme advances. The crew will spend about 10 days in orbit, testing the Orion spacecraft’s life support and navigation systems. They will swing around the far side of the Moon, seeing Earthrise from a perspective not witnessed since 1972. For the astronauts, the physical and psychological demands are immense: radiation exposure, isolation, and the constant hum of machinery. Koch, who holds the record for the longest single spaceflight by a woman (328 days), knows these stresses intimately.
Victor Glover, the first African-American to spend an extended period on the International Space Station, will serve as pilot. He has described the mission as a proving ground for the “new normal” of space travel, where diversity is not a checkbox but a necessity. The Canadian presence is also notable: Hansen, a fighter pilot and physicist, brings expertise in human physiology.
Now, the technical bottleneck. The IHM must pass a series of vacuum chamber tests at the European Space Research and Technology Centre in the Netherlands. British industry has a narrow window to deliver: the module must be integrated with the lander stack by mid-2024. Any delay would ripple through the entire Artemis schedule.
From my vantage point as a scientist, the Moon is a dead rock, a place of stark beauty and lethal vacuum. But it is also a proving ground for the technologies that may one day help us survive on a degraded Earth. The closed-loop life support systems, the solar power arrays, the recycling of water and air all have direct analogues to sustainability challenges on Earth.
As the planet warms at a rate of 0.18°C per decade, we need every technological advance we can muster. Artemis II is not a diversion from the climate crisis. It is an investment in the same spirit of human ingenuity that must now turn its full attention to preserving our biosphere. The Moon awaits. So does the more pressing work of saving our own world.
