Astronaut Talks About Being In Untethered Hot Spot
60秒科学节目（SSS）是科学美国人网站的一套广播栏目，英文名称：Scientific American – 60 Second Science,节目内容以科学报道为主，节目仅一分钟的时间，主要对当今的科学技术新发展作以简明、通俗的介绍，对于科学的发展如何影响人们的生活环境、健康状况及科学技术，提供了大量简明易懂的阐释。
Astronaut Michael Barratt spent 199 days on the International Space Station in 2009. On February 17th, 2013, he told kids about his time in space as part of the Family Science Days effort at the annual meeting of the American Association for the Advancement of Science in Boston. Questions from the children covered the basics: eating, sleeping and waste management. Then Barratt got this question from a child, whose mom then elucidated:
Kid: What happens is someone, the line goes off.
Barratt: If the light goes off?
Mom: No, no, if you’re at the station and you know how the astronauts are being held together by some kind of line or pipe. What if that snaps?
Barratt: So if you’re out on a space walk, you’re very careful about keeping yourself attached. So we always have two ways to attach yourself to the space station. If you come totally free, if you’re wearing the US space suit, you’ve got a little jetpack back there. So you pull a little control and a joystick in front of you, and you can actually fly yourself back to the station. We’ve never had to do that. But believe me, having done a couple of space walks, that is on your mind—you don’t want to become a satellite.
