[pensive music] in 1996, i was head of the solar physics team at nasa's marshall space flight center in huntsville, alabama. one thing that was going on at marshall space flight center was trying to fix hubble images. we had computer techniques that could basically put the image back together. take a star that looked blurry and turn it back into a star. we had taken a lot of the blurry hubble images and made them quite presentable. the fbi was aware we were doing all of this. and shortly after the bombing, the center director at marshall space flight center had been contacted by the fbi in atlanta, asking for help clearing up the image of the bomber. myself and my colleague paul meyer ended up really working on it. we knew that this was really important, that we were doing something that would perhaps save people's lives, if you catch him before he does it again. the first thing they gave us was a video from the night of the bombing of the backpack. it was very dark, hard to see. remember, this is 1996, when video was a vhs for consumers. notoriously poor quality. even the best one we

. >> at marshall space flight center in huntsville, alabama, nasa scientist, jennifer edmundson and corkyople at nasa, you come up with these very, very long names. >> that's why we call it mmpact. >> the key word there is autonomous. >> we want to make structures that we need without having to be tended by astronauts. >> if you have a truly sustainable presence on a lunar surface, you have to be an earth independent as possible. >> nasa was interested in 3d printing having looked at an early version almost 20 years ago. when they heard about the progress icon had made with their first houses in austin, corky clinton traveled there to take a look. >> being an engineer, i spent a lot of my time going around and looking at the size of the beads and how they went around the corners. i was impressed. >> impressed enough that nasa gave icon development money in 2020 and then two years later, a $57 million contract. >> welcome to spacelab. this is where we figure out how to build on other worlds. >> ballard and evan jensen explain the fundamental challenge. >> to bring an object roughly this si
