Crewed spacecraft means spacecraft with humans aboard. Young, or old, male or female, space travel is an equal opportunity hazardous endeavor. As of this writing, three spacefaring nations have put 559 humans into space, the Soviet Union/Russia, the United States, and China. Numerous astronauts from many other nations have hitched a ride. We are going to discuss historical, ongoing, and future efforts of getting people to space. We will mention in passing Space Stations in orbit, but that is a big topic, and well best be covered in a companion volume.
