A spacecraft traveling from Earth to Mars via this method will arrive near Mars orbit in approximately 8. 5 months, but because the orbital velocity is greater when closer to the center of mass ( i. e. the Sun ) and slower when farther from the center, the spacecraft will be traveling quite slowly and a small application of thrust is all that is needed to put it into a circular obit around Mars.

spacecraft and Earth
First conceived during the Presidency of Dwight D. Eisenhower as a three-man spacecraft to follow the one-man Project Mercury which put the first Americans in space, Apollo was later dedicated to President John F. Kennedy's national goal of " landing a man on the Moon and returning him safely to the Earth " by the end of the 1960s, which he proposed in a May 25, 1961 address to Congress.
Kennedy's goal was accomplished on the Apollo 11 mission when astronauts Neil Armstrong and Buzz Aldrin landed their Lunar Module ( LM ) on the Moon on July 20, 1969 and walked on its surface while Michael Collins remained in lunar orbit in the command spacecraft, and all three landed safely on Earth on July 24.
