NASA has bold plans to lasso an asteroid and land astronauts on it — and its already testing the suits theyd be wearing on the mission. At its Neutral Buoyancy Laboratory in Houston, the agency has been experimenting with a modified version of its iconic orange Advanced Crew Escape System (ACES) suit that would be suitable for the asteroid excursion. The big, bulky Extravehicular Mobility Unit (EMU) suits worn by astronauts on the International Space Station are simply too large for the limited space inside the Orion spacecraft that the mission would be using, so the team is trying to make the ACES suit better suited for deep space exploration, which includes making it more mobile. In the video below, you can see the modified suit being tested in an underwater environment.
