Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. [1] [2] Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially 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.

In July 2020, the Perseverance rover underwent a 200-day, 300-million-mile journey to reach Mars.After landing in February 2021 in the Jezero Crater, the robot, controlled remotely from Earth, has ...
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
NASA’s Perseverance Mars rover used its right-front navigation camera to capture this first view over the rim of Jezero Crater on Dec. 10, 2024, the 1,354th Martian day, or sol, of the mission.
Artist's rendition of Mars Express as seen by NASA's Mars Global Surveyor Image of Mars Express in orbit at Mars. 2001 Mars Odyssey was launched April 7, 2001 on a Delta II rocket and currently holds the record for the longest-surviving continually active spacecraft in orbit around a planet other than Earth at 23 years, 3 months and 17 days.
