A Hohmann transfer orbit also determines a fixed time required to travel between the starting and destination points; for an Earth-Mars journey this travel time is about 9 months. When transfer is performed between orbits close to celestial bodies with significant gravitation, much less delta-v is usually required, as the Oberth effect may be ...
Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...

Held the record for fastest human-made object at the time and the most distant one until Voyager 1 overtook in 1998. Closest approach towards Jupiter was at 02:25 UTC on 4 December 1973. Flew by Callisto, Ganymede, Europa and Io at long distances. Final signal received on 23 January 2003, 12 billion km (80 AU; 7.5 billion mi) from Earth. [5] 2
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 ...
February 11, 2012: New Horizons reaches the distance of 10 AU from the Pluto system, at around 4:55 UTC. [30] July 1, 2013: New Horizons captures its first image of Charon. Charon is clearly separated from Pluto using the Long-Range Reconnaissance Imager (LORRI). [31] [32] October 25, 2013: New Horizons reaches the distance of 5 AU from the ...
The lowest energy transfer to Mars is a Hohmann transfer orbit, a conjunction class mission which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) [citation needed] at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth. [9] [10] This would be a 34-month trip.
Mars 4 failed to enter Mars orbit and flew by it instead. [90] Mars 6: Mars 5 August 1973 12 March 1974 220 days (7 months, 8 days) The Mars 6 bus flew by Mars at a minimum distance of 1600 km. Also carried a lander. [13] Mars 7: Mars 9 August 1973 9 March 1974 213 days (7 months, 1 day) Mars 7's lander was released prematurely and missed Mars ...
