    The lowest energy transfer to Mars is a Hohmann transfer orbit, 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.

    The Mars 1M programs (sometimes dubbed Marsnik in Western media) was the first Soviet uncrewed spacecraft interplanetary exploration program, which consisted of two flyby probes launched towards Mars in October 1960, Mars 1960A and Mars 1960B (also known as Korabl 4 and Korabl 5 respectively).

  4. Delta-v budget - Wikipedia

    en.wikipedia.org/wiki/Delta-v_budget

    Delta- v in feet per second, and fuel requirements for a typical Apollo Lunar Landing mission. In astrodynamics and aerospace, a delta-v budget is an estimate of the total change in velocity (delta- v) required for a space mission. It is calculated as the sum of the delta-v required to perform each propulsive maneuver needed during the mission.

  5. Space travel under constant acceleration - Wikipedia

    en.wikipedia.org/wiki/Space_travel_under...

    Space travel under constant acceleration. Space travel under constant acceleration is a hypothetical method of space travel that involves the use of a propulsion system that generates a constant acceleration rather than the short, impulsive thrusts produced by traditional chemical rockets. For the first half of the journey the propulsion system ...

  6. Hohmann transfer orbit - Wikipedia

    en.wikipedia.org/wiki/Hohmann_transfer_orbit

    In astronautics, the Hohmann transfer orbit (/ ˈhoʊmən /) is an orbital maneuver used to transfer a spacecraft between two orbits of different altitudes around a central body. For example, a Hohmann transfer could be used to raise a satellite's orbit from low Earth orbit to geostationary orbit. In the idealized case, the initial and target ...

    Perseverance, nicknamed Percy, [ 2 ] is a car -sized Mars rover designed to explore the Jezero crater on Mars as part of NASA 's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. [ 3 ] Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at ...

    Mars Exploration Program (MEP) is a long-term effort to explore the planet Mars, funded and led by NASA. Formed in 1993, MEP has made use of orbital spacecraft, landers, and Mars rovers to explore the possibilities of life on Mars, as well as the planet's climate and natural resources. [ 1 ] The program is managed by NASA's Science Mission ...

    Viking 1. Viking 2. Mars landing sites (16 December 2020) In 1999, Mars Climate Orbiter accidentally entered Mars' atmosphere and either burnt up or left Mars' orbit on an unknown trajectory. [citation needed] There are a number of derelict spacecraft orbiting Mars whose location is not known precisely.
