Considerable effort goes into the design of space suits and space agencies across the world are always working on improvements to enhance safety and mobility of the designs. NASA is now working with Collins Aerospace to develop their next generation spacesuit for the International Space Station. The new designs are tested extensively and recently, the new design was subjected to a ZeroG flight on board a diving aircraft.
Collins Aerospace are an American technology company based in Charlotte in North Carolina. They were selected to develop the new suit as a replacement to the existing garments used by NASA. The official name of the suits are extravehicular mobility units and they have been worn for over two decades.
Once a prototype for the new suit was developed the project entered its test phase with one of the key elements, the microgravity or ZeroG test. To simulate ZeroG aircraft are taken on a parabolic flight. The pilot takes the plane to an altitude of around 24,000 feet and then pulls up increasing the climb angle to 45 degrees. Reaching an altitude of about 32,000 feet the plane is then put into a dive where the plane and its occupants experience ZeroG. For those inside, they will float around for between 20 and 30 seconds.
