Rare high-altitude clouds found on Mars
RNeuhaus
This finding is a important part to contribute for better planning of Entry, Descending and Landing.

The new high-altitude cloud layer has implications for landing on Mars as it suggests the upper layers of Mars' atmosphere can be denser than previously thought. This will be an important piece of information for future missions, when using friction in the outer atmosphere to slow down spacecraft (in a technique called 'aerobraking'), either for landing or going into orbit around the planet.

According to the MRO's aerobraking experience, it has found that the Mars' atmosphere densities varies much between the latitude and Longitudinal Seasson. What puzzle is Mars! blink.gif
