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 launched in 2011.
Sep 26, 2023 · One day on Mars lasts about 37 minutes longer than an Earth day. A year on Mars is almost twice as long as a year on Earth. Gravity on Mars is about one-third of the gravity on Earth. If you weigh 100 pounds on Earth, you would weigh 38 pounds on Mars. Mars has two moons: Phobos and Deimos.

Humanity first attempted to reach Mars near the dawn of the space age. The first satellite, the Soviet Union's Sputnik, launched in 1957; only three years later, the Soviet space program looked to extend its reach to Mars. More formally known as the Union of Soviet Socialist Republics (USSR), the Soviet Union made multiple attempts in the 1960s to ...
NASA's Mariner 4was the first craft to finally reach Mars. The spacecraft launched on Nov. 28, 1964, and was the first to fly by the planet on July 14, 1965. It sent 21 photos of its target back to Earth. Two days after Mariner 4 launched, the Soviet Union tried again with Zond 2. The spacecraft passed by Mars, but its radio failed and it did not r...
The public's image of Mars changed with the arrival of NASA's Mariner 9in November 1971. The spacecraft, which launched on May 30, 1971, arrived at Mars when the entire planet was engulfed in a dust storm. What's more, something mysterious was poking above the plumes of dust. When the debris settled to the surface, scientists discovered those unusu...
NASA's Mars Observer launched on Sept. 25, 1992. Just before it was supposed to achieve Mars orbit on Aug. 21, 1993, the spacecraft was lost. While the communication failure was never fully explained, the most likely cause was a fuel tank rupture that caused the spacecraft to spin out of contact with Earth, according to the 2018 book "Beyond Earth:...
The new millennium was a renaissance in Mars exploration. NASA's Mars Odyssey launched March 7, 2001 and arrived at the Red Planet on Oct. 24, 2001. As of early 2022, the orbiter was still conducting its extended science mission more than two decades later. Mars Odyssey has returned more than a million images, mapped Mars global distributions of se...
The Curiosity rover inspired another, called Perseverance, which landed successfully in Mars' Jezero crater on Feb. 18, 2021. Its quest is foremost to find samples with potential signs of life in them, although it also carries equipment for its numerous other investigations. Perseverance will cache its most promising samples for a future sample-ret...

Of the 26 attempts to reach Mars between 1960 and 1996, only 12 met with partial or full success. Between 1960 and 1969, the Soviet Union attempted to send eight spacecraft to Mars. Only two, Mars 1 and Zond 2, made it to interplanetary space, and controllers lost ...
