Simulator
by Thomas Werner
This picture was taken of myself and James Murray in the ASU Air Traffic Simulator where we completed our internship this semester.
The canopy and headrest design reminded me of the Deepflight experimental sub that flies like a plane and sure was fun…
This is the Space Environment Simulator (SES) at NASA Goddard Space Flight Center.
This thermal vacuum chamber exposes spacecraft components and other payloads to the environmental conditions they will experience once in space. The chamber has massive mechanical vacuum pumps, which are essentially large versions of the vacuum cleaners people use at home. To augment those, the chamber uses cryopumps to ensure that the hard vacuum of space is simulated in the test chamber. The cryopumps use liquid nitrogen to condense remaining gases out of the chamber once the mechanical pumps have done their work.
The two types of pumps work together to eliminate all but the tiniest trace of air in the chamber, down to about a billionth of Earth’s normal atmospheric pressure.
To simulate the hot and cold extremes possible in space, the thermal vacuum chamber can reach temperatures in a 600-degree range from 302 F all the way down to minus 310 F (hence the "thermal" vacuum chamber). The cylindrical chamber is 40 feet tall and 27 feet wide.
It is being used to test James Webb Space Telescope hardware using a helium shroud that allows even colder temperatures (40K and below).

Expedition 43 NASA Astronaut Scott Kelly puts on his Russian sokol suit gloves while inside the Soyuz simulator as he and Russian Cosmonauts Gennady Padalka and Mikhail Kornienko of the Russian Federal Space Agency (Roscosmos) participate in their second day of qualification exams Thursday, March 5, 2015 at the Gagarin Cosmonaut Training Center (GCTC) Soyuz training facility in Star City, Russia. The trio is preparing for launch to the International Space Station in their Soyuz TMA-16M spacecraft from the Baikonur Cosmodrome in Kazakhstan March 28, Kazakh time. As the one-year crew, Kelly and Kornienko will return to Earth on Soyuz TMA-18M in March 2016. Photo Credit: (NASA/Bill Ingalls)
The driver here is undergoing a regular rules assessment and has clearly been given an emergency scenario to deal with.
