I guess some of you are dreaming of becoming an astronaut and   62   (travel) to outer space to carry out scientific research. I once went to space. I travelled by space shuttle a spaceship that looks like a plane. Two rockets which   63   (support) by a launch tower lifted it into space   64   (quick). At a certain   65   (distant) from the Earth the rockets separated from the space shuttle and fell into the sea. Then a tracking ship picked   66   up. I did research in a base in outer space   67   (call) space station. Sometimes I went out of it to take a spacewalk. In outer space   68 (astronaut) cannot take off their spacesuits   69   protect them and provide oxygen. Up to now we human beings   70   (examine) most of the important planets in the solar system.
