If NASA returns to the moon in 2020 as planned, astronauts will step out in a brand-new space suit. It will give them new mobility and flexibility on the lunar surface while still protecting them from its harsh environment. The suit will also be able to sustain life for up to 150 hours and will even be equipped with a computer that links directly back to Earth. The new design will also let astronauts work outside of the International Space Station (ISS) and will be suitable for trips to Mars, as outlined in NASA’s program for exploration, called Constellation. “The current suits just cannot do everything we need them to do,” says Terry Hill, the Constellation space suit engineering project manager at NASA’s Johnson Space Center in Houston. “We have a completely new design, something that has never been done before.”
