A 30-minute film from NASA documents the first space walk by an American. The two astronauts, James McDivitt and Edward H. White, circled the Earth 66 times in four days before returning. White's 20-minute space walk, captured on film by McDivitt, begins about 10 minutes into the film. Unsurprisingly, White didn't want to stop, and had to be asked repeatedly to get back in the spacecraft (at about 15 minutes in). Don't miss these 41 beautiful images from the Gemini program, curated by Alan Taylor, including McDivitt's photo of White's extravehicular jaunt:

In "Why Space Exploration Is a Job for Humans," Jared Keller interviews Dr. Ian A. Crawford, a professor of planetary sciences at Bribeck College, London, who argues that replacing astronauts with robots isn't necessarily as advantageous as we might think. It casts the many missions and scientific successes of the Gemini program in a new light, as worthy of more than just our nostalgia for the golden age of manned space travel.
