 ST5 Mission
The ST5 micro-satellites successfully launched on March 22, 2006 aboard an Orbital Sciences Pegasus Rocket from Vandenberg Air Force Base, California. The official launch time was 9:03:45 a.m. EST. NASA's three micro-sats were launched to test and validate new technologies for future science missions.

ST5's objective was to demonstrate and flight qualify several innovative technologies and concepts for application to future space missions.

The ST5 Project is a part of NASA's New Millennium Program, which was created to identify, develop, build, and test innovative technologies and concepts for use in future missions. Its missions are guided by future needs of NASA's Earth and Space Science program. + ST-5 completes mission, more info
