Launch windows are sometimes but rarely exactly the same times each day. [10] Launch windows and launch periods are often used interchangeably in the public sphere, even within the same organization. However, these definitions are the ones used by NASA (and other space agencies) launch directors and trajectory analysts. [11] [12]
Mars Exploration Program (MEP) is a long-term effort to explore the planet Mars, funded and led by NASA.Formed in 1993, MEP has made use of orbital spacecraft, landers, and Mars rovers to explore the possibilities of life on Mars, as well as the planet's climate and natural resources. [1]
The program aims to send a million people to Mars, using a thousand Starships sent during a Mars launch window, which occurs approximately every 26 months. [49] Proposed journeys would require 80 to 150 days of transit time, [ 45 ] averaging approximately 115 days (for the nine synodic periods occurring between 2024 and 2041).
Because of the proximity of the Mars moons to Mars, any mission to them may also be considered a mission to Mars from some perspectives. Past missions Three missions to land on Phobos have been launched; the Soviet Phobos program in the late 1980s saw the launch of Phobos 1 and Phobos 2 , while the Russian Fobos-Grunt sample return mission was ...
EscaPADE was originally selected from a competition to be a low-cost ride-along "mission of opportunity" to hitch a ride to Mars with the Psyche spacecraft, and drop off as the spacecraft made a fly-by of Mars. Thus, it had an anticipated launch cost of nearly nothing. However, the launch of the Psyche mission was awarded to Falcon Heavy ...
Musk has been floating the idea of turning the launch site into a city for several years, with SpaceX first approaching officials in Cameron County, Texas, about the plan in 2021. Holding an ...
The Mars 1M programs (sometimes dubbed Marsnik in Western media) was the first Soviet uncrewed spacecraft interplanetary exploration program, which consisted of two flyby probes launched towards Mars in October 1960, Mars 1960A and Mars 1960B (also known as Korabl 4 and Korabl 5 respectively). After launch, the third stage pumps on both ...
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. [78] 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 ...
