Lesson 61 Dangerous descent



In future, astronauts will be required to descend from the 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 Astro which left the earth short time ago will be travelling 300 miles into space. At a certain point, the Astro will stop for a short time and an astranaut 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 Astro will have been flying through space for 17 hours and will have circled the earth a great many times. When the first radio messages have been received, the results of the trip will be announced immediately.
