Atmospheric Waves Awareness: An Explainer

There are two types of atmospheric waves that are critically important on Earth and other planets: gravity waves and planetary waves.

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.

Mars Climate Sounder confirms a Martian weather prediction

The Mars Climate Sounder team has recently confirmed a prediction of a weather phenomenon on Mars that we haven't been able to observe before.

Nighttime Water Ice Clouds Predicted by Models are Confirmed by MCS Observations

The Mars Climate Sounder instrument provides routine nightside observations of atmospheric temperature and opacity that document the presence of rapidly evolving water ice cloud layers in the Martian tropics during the northern summer season.

Mars Climate Sounder Watches Mars Weather to Prepare for Curiosity Landing

Two weeks ago Mars Reconnaissance Orbiter and Mars Climate Sounder (MCS) started a four-week campaign to support entry, descent, and landing phase for the next Mars rover, Mars Science Laboratory (or

Successor to Mars Climate Orbiter will fly aboard ExoMars

Congratulations to the Mars Climate Sounder team on winning a spot for a successor instrument aboard the next Mars orbiter, the joint NASA-ESA ExoMars, set to launch in 2016.

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.

Observing the Martian Atmosphere for Two Mars Years

June 29, 2010 was the second Martian anniversary of the start of Mars Climate Sounder (MCS) observations at Mars.

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.

Notes from this morning's Mars Reconnaissance Orbiter press conference

They held the usual pre-arrival press conference this morning for Mars Reconnaissance Orbiter. This press conference typically doesn't convey any information that people who have been paying attention don't already know.
