Answer:
Correct answer is A: Bring it home safely.
Step-by-step explanation:
The Mercury program was the space program that was initiated by the United States under the control of the U.S Air Force in 1958 and that lasted until 1963. This program had two goals, one evident and stated, and one understated. The stated and evident goal of Mercury, was to send a manned spaceflight into the Earth´s orbit and bring it back, safely. The second, and understated goal of the program, however, was to beat the Russians in what became known as the Space Race. This program was placed later on into the control of NASA, the civilian agency that was created specifically to remove control of the space program from the military.
