Army Nanosatellite On First Flight
by John Cummings
The Space and Missile Defense Command - Operational Nanosatellite Effect, or SMDC-ONE, launched on a Falcon 9 two-stage booster, a Space Exploration Technologies, Inc, or SpaceX, launch vehicle as a secondary payload. The primary payload for this flight is the SpaceX Dragon spacecraft.
The primary objective of this maiden flight is to receive data from a ground transmitter and relay that data to a ground station. The intent of this technology demonstration is to build a number of identical satellites and deploy them together into Low Earth Orbit to simulate enhanced tactical communications capability and evaluate nanosat performance.
Approximately 45 minutes after launch, SMDC-ONE deployed from the Falcon 9 trunk unit located in the second stage of the rocket and was placed into a low earth orbit.
After being dormant for 30 minutes, the nanosatellite deployed its receiver antennas. Even though in a tumbling mode, the satellite contacted the ground station at USASMDC/ARSTRAT on Redstone Arsenal, Ala., and provided a??state-of-healtha?? data.
During orbits over the next four days contact with the second ground station in Colorado Springs, Colo., will be made during orbits.
After deployment, it is expected that SMDC-ONE will remain in
orbit for approximately 30 days before dropping out of orbit.
Because of its small size and weight, SMDC-ONE is expected to be
destroyed during reentry in the atmosphere.
