Lesson 61 Dangerous Descent

In future, astronauts will be required to descend from a spaceship while it is still in space and to return to it. The ability to do this will be necessary in future flights to distant planets. Scientists are now trying to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 o’clock this evening. By that time, the Astra will have been flying through space for seventeen hours and will have circled the earth a grate many times. When the first radio messages have been received, the results of the trip will be announced immediately.
