CubeSats Launch from Vandenberg

Atlas V NROL-36On August 2, 2012 at 07:40 UT an Atlas V rocket is planned to launch a combination of 11 satellites from Vandenberg Air Force Base in California for the US Government and NASA ELaNa university CubeSats.

The primary mission will launch a pair of US Navy Ocean Surveillance Satellites (NOSS). These satellites carry equipment to track ships and aircraft by triangulation of radio transmissions. The two NOSS satellites have a combined weight of 6500 kg. They will separate a few days after being placed into a 1100 km circular orbit at 63° inclination.

Atlas V Payload illustrationThis is the first Atlas V launch with modified helium tanks in the Centaur upper stage. The change has created room in the aft skirt to accommodate 8 P-POD dispensers for CubeSats. This launch carries 11 CubeSats, to be released into 470 x 770 km, 63° orbit about 3 hours after launch and following maneuvers by the Centaur upper stage.

NASA ELaNa Launch and Deployment

3 P-Pods will carry 4 CubeSats as the NASA sponsored “ELaNa VI” cluster:

1. CINEMA (CubeSat for Ion, Neutral, Electron, Magnetic fields)

Cinema Berkeley Space Physics Research Group imageFirst in a trio of identical nano-satellites studying Space Weather effects in near-Earth space, 3U CubeSat from University of California at Berkeley,

Uplink uses a serial connection with a data rate of 9600 bps.

Downlinks for engineering telemetry and command are in the 2400-2450 MHz range; Science telemetry is in 2200-2300 MHz range.
