...such as aerospace engineering, component/composite development and fabrication, space vehicle assembly, astronaut training, zero-gravity scientific and medical experiments, microsatellite development, and space tourism. In August 2013, Houston’s City...
.... Occasionally, the reality of space makes some of these activities and foods difficult. We didn’t have to deal with zero gravity, or even try to simulate that part of a mission to Mars. Living off-grid on renewable energy, however, we did have...
...prospect. However, its spaceplane - an enlarged development of SpaceShipOne - and others under construction, provide just a few minutes of zero gravity on top of a very steep flight. As such they are useful lead-ins but to launch satellites and visit...
