The Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter) was a robotic space probe launched by NASA on December 11, 1998, to study the Martian climate, Martian atmosphere, and surface changes and to act as the communications relay in the Mars Surveyor '98 program for Mars Polar Lander.
Mars Surveyor '98 was a mission in NASA's Mars Exploration Program that launched the Mars Climate Orbiter and the Mars Polar Lander to the planet Mars.The mission was to study the Martian weather, climate, water and carbon dioxide (CO 2) budget, to understand the reservoirs, behavior, and atmospheric role of volatiles and to search for evidence of long-term and episodic climate changes.
Mars Global Surveyor is expected to crash onto the surface of the planet by 2047. The fate of the Soviet's three Mars program orbiters and Phobos 2 remains unclear, but they are still presumed to be in orbit. [3] In 1999 the Mars Climate Orbiter impacted the Martian atmosphere.
The Mars Observer spacecraft, also known as the Mars Geoscience/Climatology Orbiter, was a robotic space probe launched by NASA on September 25, 1992, to study the Martian surface, atmosphere, climate and magnetic field.
A recently published study has determined that the Mars Reconnaissance Orbiter's approach to handling water data is flawed, potentially invalidating some earlier discoveries of salty water flows.
The Mars Polar Lander, also known as the Mars Surveyor '98 Lander, was a 290-kilogram uncrewed spacecraft lander launched by NASA on January 3, 1999, to study the soil and climate of Planum Australe, a region near the south pole on Mars. It formed part of the Mars Surveyor '98 mission. On December 3, 1999, however, after the descent phase was ...
Mars Climate Orbiter: Burned up in the Martian atmosphere 11 October: Galileo: 1st flyby of Io: 26 November: Galileo: 2nd flyby of Io 3 December: Mars Polar Lander: Crash-landed at Planum Australe, Mars 3 December: Amundsen and Scott: Subprobes lost in Mars Polar Lander crash-landing
The fate of Mars Climate Orbiter (1999) is unknown, but it is thought to have burnt up in the atmosphere before impacting. Mariner 9, which entered Mars orbit in 1971, is expected to remain in orbit until approximately 2022, when the spacecraft is projected to enter the Martian atmosphere and either burn up or crash into the planet's surface.
