Student-built satellite prepared for mission fast track

KIRTLAND AIR FORCE BASE, N.M. -- Approximately 18 months after edging out 12 other college teams in the Nanosat-3 competition, The University of Texas at Austin's winning structure arrived at the Air Force Research Laboratory's Space Vehicles Directorate, Kirtland Air Force Base, N.M., in June for integration and testing prior to launch.

Referred to as the Formation Autonomy Spacecraft with Thrust, Relnav, Attitude and Crosslink (FASTRAC), the student-constructed satellite, weighing 110 pounds, will split into two separate units following lift off for formation flying in low Earth orbit about 220 miles above the planet's surface.

FASTRAC serves as the second space flight opportunity for the University Nanosatellite Program, which began in 1999. Initiated by the Air Force Office of Scientific Research and the Space Vehicles Directorate, the project provides U.S. colleges and universities with an incentive to design, as well as to develop satellites for potential experimental missions. Each participating school receives up to $55,000 per year in funding from the AFOSR to build a vehicle capable of operating in the cosmos. As program administrator, the Space Vehicles Directorate also offers design support to the competing teams and organizes all competition events, as well as conducts design reviews, and provides the flight testing and post-launch supervision on the selected vehicle. In December 2004, the program's inaugural venture launched into space, Nanosat-2, also known as Three Corner Sat due to the geographical location of the tri-member team of Arizona State University, University of Colorado at Boulder, and New Mexico State University, did not complete its mission as a result of a technical problem in the booster rocket, which placed the system in an improper orbit.

"The University Nanosatellite Program is raising the next generation of aerospace industry workers," said Scott Franke, University Nanosatellite Program manager, AFRL's Space Vehicles Directorate. "We are building expertise in satellites and other spacecraft, and we want to grow that expertise in this country since the project is only open to U.S. colleges."

Planned for a six-month mission, FASTRAC, measuring about 2 feet wide and 2 feet high, features two primary experiments, a Global Positioning System Relative Navigation Experiment and the Micro-discharge Plasma Thruster. During operational assessments performed at Kirtland Air Force Base, the GPS trial proved successful. Employing off the shelf technology, the spacecraft's twin sections demonstrated acknowledgement of each portion's position so as to perform formation flying. Slated to propel the satellite autonomously at certain attitudes, the on-orbit thruster trial will be performed until all fuel has been expired. Meanwhile, functional testing of the spacecraft progresses with an end date estimated for December. One month before, program personnel will brief the Department of Defense's Space Exploration Review Board, convening in Arlington, Va., in an effort to secure a launch vehicle for FASTRAC. Nonetheless, other potential lift off options, dependent on allotted space and timing, are currently being investigated.

"The University Nanosatellite Program is unique. It is, to my knowledge, the only federal government-sponsored program that is open nationally for U.S. university participation," said the University Nanosatellite Program manager. "The Air Force Research Laboratory has really recognized the ground-breaking nature of this program."

Following launch, the FASTRAC team will monitor the Nanosat-3 mission at a ground station located on The University of Texas at Austin's campus. In addition, a spacecraft operations center has been planned for inclusion in the school's Aerospace Engineering Building. While a core group of 15 Lone Star State collegians await FASTRAC's voyage into the cosmos, the University Nanosatellite Program has accomplished the majority of reviews on the 11 institutes of higher learning seeking the Nanosat-4 award, which will be announced in spring 2007. Unlike the previous contest, the panel of judges, comprised of representatives from the aerospace industry, the National Aeronautics and Space Administration, as well as from AFRL, could choose two teams to test their hardware in the cosmos.

"Our program is a technology incubator. It is a way for the students to try out new ideas at a low cost," Mr. Franke said. "It is a creative and risk-taking environment where failure is an option, not a problem."
