An article by Dirk Schulze-Makuch (Washington State University) and Paul Davies (Arizona State University) from the book The Human Mission to Mars: Colonizing the Red Planet [12] summarizes their rationale for Mars to Stay: [Mars to stay] would obviate the need for years of rehabilitation for returning astronauts, which would not be an issue if ...
Here's everything to know about the Mars rock samples, potential plans to get them to Earth and what's next for Perseverance: The year ahead in space travel: Uncrewed lunar missions and 1st ...
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.
The landing took place shortly after Mars passed through its northern vernal equinox (Ls = 5.2°), at the start of the astronomical spring, the equivalent of the end of March on Earth. [ 84 ] The parachute descent of the Perseverance rover was photographed by the HiRISE high-resolution camera on the Mars Reconnaissance Orbiter (MRO).
Mars is the celestial body in the solar system with the most similarities to Earth. A Mars sol lasts almost the same as an Earth day, and its axial tilt gives it similar seasons. There is water on Mars, most of it frozen at the Martian polar ice caps, and some of it underground. However, there are many obstacles to its habitability.
There’s also round-trip light time—that’s how long it takes a command to go from Earth to the spacecraft and back. In order to receive data on Earth, you have to command the spacecraft to start sending it 4.5 hours earlier. Likewise, if you want to send something, you have to send it to a point the spacecraft is going to be in 4.5 hours.

The launch window, when the positions of Earth and Mars were optimal for traveling to Mars, opened on July 17, 2020, and lasted through August 15, 2020. [83] The rocket was launched on July 30, 2020, at 11:50 UTC, and the rover landed on Mars on February 18, 2021, at 20:55 UTC, with a planned surface mission of at least one Mars year (668 sols ...
