Preparing the Vehicle Assembly Building for NASA's Next Rocket

A view from below in High Bay 3 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center shows three work platforms installed for NASA’s Space Launch System (SLS) rocket. The platforms will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. via NASA http://ift.tt/1Qn5o6T

April 14, 1981, Landing of First Space Shuttle Mission

The rear wheels of the space shuttle orbiter Columbia touched down on Rogers dry lake at Edwards Air Force Base, NASA's Armstrong Flight Research Center (then Dryden), California, to successfully complete a stay in space of more than two days. Astronauts John W. Young, STS-1 commander, and Robert L. Crippen, pilot, were aboard the vehicle. via NASA http://ift.tt/1TTGD8R

T-38C Passes in Front of the Sun at Supersonic Speed

An Air Force Test Pilot School T-38C passes in front of the sun at a supersonic speed, creating shockwaves that are caught photographically for research. NASA is using a modern version of schlieren imagery to visualize supersonic flow phenomena with full-scale aircraft in flight. The results will help engineers design a quiet supersonic transport. via NASA http://ift.tt/1YrJhlF
