Humans have long dreamed of setting foot on the Moon and other planetary bodies such as Mars. Since the 1960s, space travellers have donned suits designed to protect them from the vacuum of space and stepped out into the unknown.
However, the Polaris Dawn mission, which is to include the first spacewalk organised by a private company, has been delayed. This is due to complications with the design and development of a suitable spacesuit.
Moon suits are also one of the key elements of Nasa’s Artemis lunar programme that have yet to be delivered. A report released in November 2023 said that the contractor making the suits is having to revisit aspects of the design provided by Nasa, which could introduce delays.
Yet the first spacewalk, by the Soviet cosmonaut Alexei Leonov, took place in 1965. Later, 12 Nasa astronauts would walk on the lunar surface, between 1969 and 1972, using technology that would be eclipsed by today’s smartphones. So it’s not unreasonable to ask why it can still be difficult to design and build spacesuits to do the same thing.
Much has changed since the Apollo missions planted flags on the Moon. The geopolitics driving space travel have shifted, and spacesuits are no longer expected to be just a form of protection. Instead, they are a critical way to improve the productivity of astronauts. This involves a rethink of not just the suits themselves, but the technology that supports them.
