For purposes of enumerating Mars years and facilitating data comparisons, a system increasingly used in the scientific literature, particularly studies of Martian climate, enumerates years relative to the northern spring equinox (L s 0) that occurred on April 11, 1955, labeling that date the start of Mars Year 1 (MY1).
Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
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.
A collection of Martian rocks could reveal details about potential past life on the Red Planet – but first NASA has to get them back to Earth.. For years, the U.S. space agency's Perseverance ...
The Mars 2 orbiter sent back data covering the period from December 1971 to March 1972, although transmissions continued through August. It was announced that Mars 2 and Mars 3 had completed their missions by 22 August 1972, after 362 orbits. The probe, combined with Mars 3, sent back a total of 60 pictures.
You probably don’t need a recap, but let’s take a look at some of what’s happened since reckless Mars turned retrograde on Dec. 6, 2024, first in Leo, the sign of royals and the elite.
2025 has been consumed with cosmic chaos, and the year has just begun.. We kicked off the new year amidst three planetary retrogrades. Uranus, who is the revolutionary and rebellious celestial ...
