By now, you've heard that NASA emailed a socket wrench to the ISS. While I think this is awesome and Made In Space is revolutionizing the way we'll get things to space, the real interesting point is how NASA will treat anything made on the ISS that hasn't gone through its, um, "very thorough" safety review.
For the record, the wrench made will not be officially used (there is already a full tool set on station (https://www.flickr.com/photos/timpeake/sets/72157634315750824/
)) but will very likely be returned to Earth for comparison to wrench made on the ground. Actually, a few weeks ago Butch asked for a backscratcher. I thought that would have been cooler. :O)
