The MAVEN spacecraft has completed the first of five deep-dip maneuvers designed to gather measurements closer to the lower end of the Martian upper atmosphere. “During normal science mapping, we make measurements between an altitude of about 150 km and … Continue reading →

MAVEN instruments all collecting data as expected during deep-dip. The initial MAVEN deep-dip campaign continues to go well, as the NASA ‪#‎Mars‬ orbiter maintains its targeted atmospheric density corridor between 2.0 – 3.5 kg/km³. All of the MAVEN science instruments … Continue reading →

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 →

On February 10, MAVEN carried out its first walk-in maneuver of the current “deep-dip” campaign. This lowered the periapsis of the MAVEN spacecraft about 20 km to an altitude of about 133 km. The campaign will continue tomorrow with another … Continue reading →

MAVEN will begin first ‘deep dip” campaign on February 10th. MAVEN’s primary mission includes five 5-day “deep-dip” campaigns, in which the periapsis (lowest point in the orbit) is lowered from about 93 miles (150 km) to about 77 miles (125 … Continue reading →

Early discoveries by NASA’s newest Mars orbiter are starting to reveal key features about the loss of the planet’s atmosphere to space over time… The observations reveal a new process by which the solar wind can penetrate deep into a … Continue reading →
