Description

Doug Litteken discusses the importance of using inflatable structures for a human mission to Mars and tackles some of the myths associated with these space vehicles. Litteken is an engineer at NASA Johnson Space Center focusing on composite and inflatable lightweight structures for human rated space vehicles. He is a member of the JSC Speakers Bureau and enjoys sharing his excitement for space exploration with audiences of young and old. NASA Deputy Administrator Lori Garver announced a newly planned addition to the International Space Station that will use the orbiting laboratory to test expandable space habitat technology. NASA has awarded a $17.8 million contract to Bigelow Aerospace to provide a Bigelow Expandable Activity Module (BEAM), which is scheduled to arrive at the space station in 2015 for a two-year technology demonstration. The BEAM is scheduled to launch aboard the eighth SpaceX cargo resupply mission to the station contracted by NASA, currently planned for 2015. After the module is berthed to the station's Tranquility node, the station crew will activate a pressurization system to expand the structure to its full size using air stored within the packed module. Astronauts periodically will enter the module to gather performance data and perform inspections. Following the test period, the module will be jettisoned from the station, burning up on re-entry. SpaceX CRS-8, also known as SpX-8, is a spaceflight cargo resupply mission to the International Space Station scheduled for 2015. The mission has been contracted by NASA and will be flown by SpaceX.
