Mach 1 on Mars can be about 240 m/s (790 ft/s) while it is about 332 m/s (1,090 ft/s) on Earth. [21] The Daedalus proposal in the canceled Mars Scout program designed a Mars glider that would fly over 400 km (250 mi) along the Coprates Chasma [22] Proposed Mars airplane concepts include: ARES (Aerial Regional-scale Environmental Survey) [23]
In The Martian, by Andy Weir, the spaceship Hermes uses a constant thrust ion engine to transport astronauts between Earth and Mars. In Project Hail Mary, also by Weir, the protagonist's spaceship uses a constant 1.5 g acceleration spin drive to travel between the Solar System, Tau Ceti and 40 Eridani.
On April 7, 2006, the spacecraft passed the orbit of Mars, moving at roughly 21 km/s (76,000 km/h; 47,000 mph) away from the Sun at a solar distance of 243 million kilometers. [ 98 ] [ 99 ] [ 100 ] Asteroid 132524 APL
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.
The American Vision for Space Exploration, originally introduced by U.S. President George W. Bush and put into practice through the Constellation program, had as a long-term goal to eventually send human astronauts to Mars. However, on February 1, 2010, President Barack Obama proposed cancelling the program in Fiscal Year 2011.
Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars ...
Ingenuity was designed to fly five times in 30 Mars sols (31 Earth days), but operated far above expectations, making its 72nd and final flight on January 18, 2024 , 977 Mars sols (1,004 Earth days) after its first flight. Its rotor blades were damaged on the last flight's landing, causing NASA to retire the craft.
It takes 250 days (0.68 years) in the transit to Mars, and in the case of a free-return style abort without the use of propulsion at Mars, 1.5 years to get back to Earth, at a total delta-v requirement of 3.34 km/s. Zubrin advocates a slightly faster transfer, that takes only 180 days to Mars, but 2 years back to Earth in case of an abort.
