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.
Successful Mars flyby (NASA) Launch: November 28, 1964. Mars flyby: July 14, 1965. Mariner 4 was the first spacecraft to fly by Mars and obtain close-up pictures of the Red Planet, passing within 9,844 kilometers (6,117 miles) of Mars. It then took four days to transmit the data back to Earth.
The first crewed Mars Mission, which would include sending astronauts to Mars, orbiting Mars, and returning to Earth, is proposed for the 2030s. [ 2 ] [ 50 ] [ 51 ] [ 52 ] Technology development for US government missions to Mars is underway, but there is no well-funded approach to bring the conceptual project to completion with human landings on Mars by the mid-2030s, the stated objective.

The former Soviet Union started off the race to Mars with a series of Mars spacecraft. Among them, the Mars 1 mission was able to send back some data about the Red Planet before mission controllers lost contact with it a few months after launch. Mars 2 got to Mars safely, but its rover crashed landed on the surface. Mars 3, 4, 5 and 6 were partiall...
Mariner 9 arrived during a planet-wide dust storm and successfully put itself into orbit. After the dust settled, the spacecraft returned 7,329 images that revealed 85 percent of the surface of the planet. Those images revealed surface features familiar to us on Earth, including river beds, craters, flood plains, canyons, and volcanic features. In ...
The bad luck with missions continued into the 1990s with the loss of NASA’s Mars Observer mission in 1993. An investigation suggested that a fuel leak may have caused the mission to fail. Mars 96 failed at launch in 1996, the Japanese Nozomi (Planet B) mission never entered Mars orbit. The Mars Climate Orbiter (NASA) crashed to the Martian surface ...
In the first two decades of the 21st century, space agencies have had more successful missions. NASA’s Mars Odyssey, the European Space Agency’s Mars Express led off the march to Mars. They are still currently operating as of this writing. The Mars Exploration Rovers A and B, also known as Spirit and Opportunity, settled onto the Martian surface in...
The first U.S. mission to land a spacecraft safely on Mars and return images of the surface, Viking 1 was part of a pair of probes seeking signs of life on Mars. (1975-1982 ) Read More
