1. The document discusses topics related to space travel and living in space in the future. It presents ideas from astronaut Jeremy Hale about whether people will live in space stations and on other planets. 2. Hale believes that people will live in space stations in the future, as some astronauts already live on the International Space Station for weeks or months. Future space stations will be much larger and resemble cities. 3. Hale also thinks people will live on other planets, but that it will not be easy due to environmental challenges. The moon may become a new home for people, with thousands taking rockets to live there. Special space suits will allow living on planets with extreme temperatures.
