Of course, Silicon Valley has grown way beyond NASA since the Apollo program was leaning on researchers from Stanford, nearby University of California at Berkeley and a number of small companies that started to dot the area in the 1960s. But in the crucial early years of the Valley's techno...
NASA has sent robotic probes to other planets in our solar system, and helped astronomers gaze into the depths of the universe. Beyond all that, NASA also has used its satellites and scientists to help us to
They're removed and disposed of once the spacecraft has landed. The liquid waste is sent into space. How The International Space Station Handles Waste On the International Space Station, liquid wastes are recycled through a special water treatment plant and turned back into drinking water. ...
