Key Goals of the MAVEN Mission: Understand atmospheric loss: MAVEN aimed to determine how much of Mars' atmosphere has been ...

Scientists are able to measure the rate of atmospheric and water loss and extrapolate back to deduce how thin atmosphere Mars' atmosphere might once have been, and how much water Mars may have had ...

The size of the planet and the temperature of its upper atmosphere determines the rate of loss. ISRO ’s MOM tracks planet-encircling storm on Mars ISRO pegs Mars’ atmospheric deterioration to ...

The paper, led by Planetary Science Institute Research Scientist Peter Buhler, describes how 3.6 billion years ago, carbon dioxide froze out of Mars' atmosphere and deposited on top of a water ice ...

A longstanding mystery that has puzzled scientists for years might finally have a solution: how Mars managed to sustain rivers and seas long after the planet began to cool and its atmosphere thinned.

The simulations revealed that in the young Mars, the magnetosphere may have ... field eventually become inhospitable with loss of their atmosphere, the scientists added. The researchers believe ...

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving ...
