Very soon, a robot surgeon may begin its orbit around our planet — and though it won't quite be a metallic, humanoid machine wearing a white coat and holding a scalpel, its mission is fascinating nonetheless.
On Tuesday (Jan. 30), scientists will be sending a slew of innovative experiments to the International Space Station via Northrop Grumman's Cygnus spacecraft. It's scheduled to launch no earlier than 12:07 p.m. ET (1707 GMT) and, if all goes to plan, arrive at the ISS a few days later on Feb. 1.
