Mars Reconnaissance Orbiter

 2005-029A


6.5m box + 3-m dish with a 6 x 13m solar array pair, 13.6m span. LMA Denver. The main instrument is the 0.5m HiRISE telescope; the spacecraft has a 3m dish HGA allowing much higher data rate than earlier missions.

Operationally in 225 x 320 km polar Mars orbit, south polar periapsis and ascending node at 1510 LT.

Launch by Atlas V 401. Initial miss parameter 80000 km (J. Ray 2005, Spaceflightnow.com Aug 25)
