![]() Around the walls the air slows down to a point where the velocity is zero but as you move away from the wall toward the air stream the velocity gradually increases. Here students participated in an experiment that involved the turbulence created by the flowing air rushing against the walls of the wind tunnel. They were able to see the "Life Saver" wind tunnel. Students later paid a visit to the Fluid Dynamics Lab, a lab where many testing has been done for both sport companies and the media, including the 2014 soccer world cup ball, and TV’s Mythbusters. To them it is just as good as a telescope in space, without all the hassles of space travel, and with more returns to Earth. Water vapor in our atmosphere blocks inferred light from hitting us on Earth, however getting the telescope up in the stratosphere lets 80% more inferred get through. Teachers and scientists across the nation and from Germany have the opportunity to perform experiments on a 10 hour flight. Sophia is a renovated Boing 747 that has been modified to contain a 2.5 meter diameter inferred telescope, the world’s largest movable telescope. Soon after, students were fortunate to with another NASA scientist, Dana Backman who works on SOFIA, a NASA, DRL (the German space agency) joint project. Alex Mazhari, from last night’s panel of experts, explained how each machine worked and what its purpose was. The Space Shop works as an open 3D printing lab where engineers, scientists and other professionals can prototype ideas for products. The students also visited the Space Shop, where ideas come to life as laser cutters and 3D printers, along with various other machines that cut or shape parts of machines for engineers to compile together. The pedals are still used for experiments studying exercise. The smaller centrifuge used to be human powered, but has since been modified to use an engine. Students got the opportunity to sit in the centrifuge chair, take pictures and explore the spinning contraption. Daniel Morgan explained that one end of the large centrifuge is used for human experiments and the other for non-human ones. ![]() ![]() Among other things, these machines study how humans react in conditions of up to 5 g’s, though the centrifuge can go up to 20 g’s. Students then went to visit two human centrifuges. Receiving help from NASA interns, scholars controlled a lunar robot model. ![]()
