For decades, space agencies have relied on astronauts to take precarious and time-consuming spacewalks, but today, space station operators are increasingly turning to robots to perform tasks in orbit.

Why it matters: Using robots instead of astronauts for routine spacewalks would make spaceflight safer and more efficient, experts say, freeing up humans to only take walks in space during an emergency or for delicate experiments in microgravity.

NASA's newest spacesuits are designed to allow astronauts to explore the Moon as never before.

Why it matters: The new spacesuits are a key component of NASA's Artemis mission, which is expected to bring humans back to the surface of the Moon by 2024, as directed by the Trump administration.
