How much atmosphere has Mars lost?
A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists. Previous measurements of this tracer – … Continue reading

MAVEN: High solar wind pressure hastens loss of atmosphere
New MAVEN research shows that high solar wind pressure influences Mars’ magnetic fields in ways that can increase the global loss of atmosphere to space. Planetary atmospheres are constantly bombarded by energy and radiation from the Sun, and over time … Continue reading

MAVEN: Aerobraking to lower the orbit
The MAVEN spacecraft today [March 7] performed an aerobraking maneuver (with a 0.2 m/s ∆V) to decrease the periapsis, or lowest, altitude by 1.2 km. MAVEN’s periapsis altitude is now 125.5 km above the surface of Mars and the apoapsis, … Continue reading
