On Thursday, February 4, the world lost the last of the Apollo 14 astronauts. Edgar Dean Mitchell, U.S. Navy test pilot and the sixth person to walk on the Moon, passed away in his sleep near his Florida home at the age of 85. Though it was his only flight into space, Apollo 14 provided the rather insightful Mitchell with an opportunity to test the bounds of the human mind in ways sometimes only he knew of at the time. Characterized later as the “Overview Effect,” he described the space travel experience as one that shifted his own beliefs about human existence, though having an openness to such a change was always a part of Mitchell’s way of life.

Apollo artifacts have begun to receive increased scrutiny in light of recent discussions about returning humans to the Moon and the upcoming 50th anniversary of the historic Apollo missions. What did astronauts of the 1960s and 1970s bring back from the Moon? What was left behind? And how can we verify the authenticity of any of those objects if they have been or will be recovered?

When most people think of emergency fixes in space, the first incident that comes to mind is the famous Apollo 13 mission. The astronauts fashioned duct tape and surplus materials into air filtration canisters in the lunar module to keep all three astronauts alive for the entire trip home.

Gene Kranz is best known for his stellar performance as flight director for the ill-fated Apollo 13 mission. But Kranz is also known for another thing: his white vests. Kranz’s vests had legendary status around mission control, and also in the minds of the public after actor Ed Harris wore an exact replica of Kranz’s most famous vest in the 1995 movie, Apollo 13. Kranz’s vests represented the strong and can-do approach that pervaded his mission control team, especially during the Apollo 13 mission in which the astronauts’ lives were at stake.

There's more to these suits than meets the eye.

We’ve received a few comments and questions about why our stretch goal for the Neil Armstrong #RebootTheSuit Kickstarter project is Alan Shepard’s Mercury Freedom 7 spacesuit. The short answer is that the two suits bracket the ideas and accomplishments of the Apollo space program.

One of my earliest memories is of watching the Moon landing on TV with my dad. I was barely four years old, so the whole thing really kind of went over my head. I do remember being upset that "Mr. Dressup" had been pre-empted. Also, I was fascinated by the fact that my dad was practically climbing into the TV, he was so excited! (He was a science teacher—genes that skipped me, sadly!) I learned that day, if people could walk on the Moon, anything was possible.

First, let’s talk about terminology. When we talk about putting on or taking off a spacesuit, we frequently use the terms “donning and doffing.”
