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.
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 ...
Perseverance (rover) Perseverance. (rover) Self-portrait by Perseverance in September 2021 at Rochette, a rock and the site of the first core samples of the Mars 2020 mission. Perseverance, [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 ...
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 ...

Lost when the Mars 2 lander crashed into the surface of Mars. 16 Mars 3: Mars 3 (4M No.172) 28 May 1971 Soviet Union: Orbiter Successful
Curiosity is a car-sized Mars rover exploring Gale crater and Mount Sharp on Mars as part of NASA's Mars Science Laboratory (MSL) mission. [2] Curiosity was launched from Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC.
Both of these are the record for the largest total number of spacewalks by a male and a female, and the most cumulative time spent on spacewalks by a male and a female. Man – Anatoly Solovyev, 16 spacewalks for a total time of 82 hours, 21 minutes. [46] Woman – Peggy Whitson, 10 spacewalks for a total time of 60 hours, 21 minutes. [47] [48 ...
The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [ 6 ] is a NASA space probe launched in 2018 with the mission of making observations of the outer corona of the Sun. It will approach to within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ][ 8 ] from the center of the Sun, and by 2025 will ...
