In the late 1950's, improvements in technology allowed the first man-made objects to be launched into space to orbit the earth. although these early spacecrafts were unmanned, they still to gather information about the upper layers of the atmosphere. by the early 1960's, the first manned space shuttles were launched. how have these manned and unmanned trips encourage scientific discoveries? a. manned trips are able to bring back data, such as photographs, while unmanned trips cannot collect data at all. b. manned trips allow humans to analyze discoveries personally, while unmanned trips allow discoveries to be made in dangerous areas. c. manned trips result in more interesting facts being found, while unmanned trips rarely result in new information. d. manned trips collect scientifically accurate data to be analyzed, but unmanned trips only collect interesting, yet inaccurate, data.

The correct answer would be option B. Manned trips allow humans to analyze discoveries personally, while unmanned trips allow discoveries to be made in dangerous areas.

Explanation:

Manned trips to the space are the trips in which people are present and go themselves into the space to gather information about the new things, whereas unmanned trips are the trips on which there are no person on the space shuttle. The shuttles are automatically controlled and go into the space, complete their work and come back. Manned trips are no doubt more beneficial than unmanned trips because unmanned trips are programmed to do the specific tasks and they won't do anything other than the planned one. Whereas manned missions are more successful as the astronauts within the space shuttles complete their tasks and also can look and see other things which they think are beneficial or new for them. They collect data about them and bring the information back to the earth. So manned trips usually result in more interesting facts being found while unmanned trips rarely result it new information.
