Mysterious plumes in Mars atmosphere
Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet. On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the … Continue reading
MAVEN: Second ‘walk-in’ maneuver succeeds
The second #MAVEN deep-dip maneuver was executed yesterday (Feb. 11, 2015), with a delta-v (∆V) of 0.6 m/sec., which lowered the periapsis of the spacecraft by another 4 km. The first maneuver was carried out on Tuesday (Feb. 10) and … Continue reading
