1999年9月30日 · A failure to recognize and correct an error in a transfer of information between the Mars Climate Orbiter spacecraft team in Colorado and the mission navigation team in California led to the loss of the spacecraft last week, preliminary findings by NASA's Jet Propulsion Laboratory internal peer review indicate.

1999年9月23日 · NASA's Mars Climate Orbiter is believed to be lost due to a suspected navigation error. Early this morning at about 2 a.m. Pacific Daylight Time the orbiter fired its main engine to go into orbit around the planet.

An international fleet of eight orbiters is studying the Red Planet from above including three NASA orbiters: 2001 Mars Odyssey, Mars Reconnaissance Orbiter, and MAVEN. These robotic explorers have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.

Orbit and Rotation As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day."

Major advances in the understanding of the present and past Mars climate system are most likely to be accomplished by in situ meteorological surface measurements operating from both a network configuration and individual stations.

2018年2月9日 · Two instruments for studying the atmosphere -- the Mars Color Imager (MARCI) and Mars Climate Sounder (MCS) -- continue to build on nearly six Mars years (about 12 Earth years) of recording weather and climate.

2019年5月15日 · NASA's Mars Reconnaissance Orbiter (MRO) hit a dizzying milestone this morning: It completed 60,000 loops around the Red Planet at 10:39 a.m. PDT (1:39 p.m. EDT). On average, MRO takes 112 minutes to circle Mars, whipping around at about 2 miles per second (3.4 kilometers per second).

2018年1月23日 · The Mars Climate Sounder on MRO can scan the atmosphere to directly detect dust and ice particles and can indirectly sense water vapor concentrations from effects on temperature.

After the successful launch last week of the Mars Climate Orbiter from Pad 17A, the launch teams have begun to refurbish the pad for the erection of our Delta II rocket. The rocket itself is now here at Kennedy Space Center and in preparation for beginning the build-up of stages next week.
