Mysterious tides in the Martian atmosphere

Observations made by the Mars Climate Sounder, an instrument aboard NASA’s Mars Reconnaissance Orbiter, have revealed new information about atmospheric tides on the Red Planet.

Third Martian Anniversary for Mars Climate Sounder

May 16, 2012 is the third martian anniversary of the start of Mars Climate Sounder (MCS) observations from Mars Reconnaissance Orbiter. MCS started measuring the atmosphere of Mars three Mars years ago, on September 24, 2006. We can now compare the weather and behavior of the atmosphere in three different years, and find the temperature differences to be surprisingly large.

Tracing the Big Picture of Mars' Atmosphere

One of the instruments on a 2016 mission to orbit Mars will provide daily maps of global, pole-to-pole, vertical distributions of the temperature, dust, water vapor and ice clouds in the Martian atmosphere.

Mars Climate Sounder Collects 20 Millionth Sounding

Last week Mars Climate Sounder collected its 20 millionth sounding at Mars. Mars Climate Sounder is scanning without problems, collecting science observations of the atmosphere of Mars. Mars Climate Sounder has now been observing Mars for over 17 months (three quarters of a Mars year and also approximately three quarters of the Mars Reconnaissance Orbiter primary science mission).

Millions of soundings yield clues to Mars' weather

Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.
