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 ...
The Mars time of noon is 12:00 which is in Earth time 12 hours and 20 minutes after midnight. For the Mars Pathfinder, Mars Exploration Rover (MER), Phoenix, and Mars Science Laboratory missions, the operations teams have worked on "Mars time", with a work schedule synchronized to the local time at the landing site on Mars, rather than the ...
The Darian Defrost Calendar, however, uses the Rotterdam System [7] to create new names for the Martian months out of patterns relating letter choice and name length to month order and season. The Utopian Calendar , devised by the Mars Time Group in 2001, also has additional suggestions for nomenclature modification.

An areosynchronous orbit that is equatorial (in the same plane as the equator of Mars), circular, and prograde (rotating about Mars's axis in the same direction as the planet's surface) is known as an areostationary orbit (AEO). To an observer on the surface of Mars, the position of a satellite in AEO would appear to be fixed in a constant ...
1953: Mars Project 's technical appendix was published in English by the University of Illinois Press as The Mars Project. [10] late 1950s: This Week published excerpts from the unpublished Mars Project novel. [6] 2006: The Mars Project novel was published by Apogee Books as Project Mars: A Technical Tale. [1]
“Leaving a 2 (degree Celsius) warmer Earth for Mars would be like leaving a messy room so you can live in a toxic waste dump,” they wrote in the book’s introduction. This interview has been ...
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.
