The Soyuz space capsule that carried Princeton Engineering’s entrepreneur-in-residence Greg Olsen back to earth from his journey into space in 2005 goes on display today through October 18 at  Princeton Market Fair in West Windsor, N.J.

Olsen, the third private citizen to travel in space, re-entered the atmosphere in the Soyuz TMA-6 capsule accompanied by one American astronaut and one Russian cosmonaut. The capsule landed by parachute in the desert of Kazakhstan. Scorch marks on the capsule are from the heat of re-entry.

Olsen, a research scientist and the founder of Sensors Unlimited, devotes much of his time to inspiring school-age children to pursue careers in science and engineering. Here is a very fun video of Olsen drinking water in space.
