Hubble Space Telescope observations of Mars [PDF]

Hubble Space Telescope (HST) afforded the possibility of resolving features as small as 100 km on the Martian surface even when it is at the far point of its orbit. Therefore it is ideally suited for monitoring seasonal changes on the red planet.

Seasonal Water "Pump" in the Atmosphere of Mars: Vertical Transport to the Thermosphere

, 2019
We present results of simulations with the Max Planck Institute general circulation model (MPI-MGCM) implementing a hydrological cycle scheme. The simulations reveal a seasonal water "pump" mechanism responsible for the upward transport of water vapor ...
