NASA astronaut Ed Gibson went to space in 1973 as part of the Skylab 4 mission, the final crew to visit the only fully-US operated space station. He was the last person out the door.

Gibson was selected by NASA as a scientist-astronaut and was part of the support crew for Apollo 12 before being selected to spend time on the space station.

We spoke to him about his time on board the station, the food he eat while in space, and whether he would go up to space again if given the opportunity.
