| NEW DATA RELAY SATELLITE TO HELP REPLENISH EXISTING ON-ORBIT FLEET
| G01-072 | 12/04/01 | 00:00:00 | NASA is ready to launch the second in a series of three advanced Tracking and Data Relay Satellites. Known as TDRS-I, it will extend the lifetime of current F1-F7 fleet, which has served numerous national and international missions since 1983. TDRS-I will provide high data rate communication links with the Space Shuttle, International Space Station, Hubble Space Telescope, and a host of other Earth orbiting spacecraft, as well as tracking services for expendable launch vehicles.

TAPE CONTENTS: |
| ITEM (1): TDRS Animations - The TDRS-l spacecraft will be deployed into a 22,300 mile, geosynchronous orbit above the Earth and will maintain this fixed position while following the motion of low-earth orbiting satellites. Aside from communications, it will also track user satellites to help determine their exact location in space. TDRS-l will also provide increased bandwidth and greater tuning flexibility for relaying enormous amounts of science data, and digital TV images from space.

| ITEM (2): TDRS Data Delivery - The network also relays large volumes of data - voice, television, and scientific - from several orbiting scientific or manned missions back to their respective ground control centers. Two 15-foot antennas aboard the spacecraft will support the International Space Station with high-resolution digital television, as well as dump enormous volumes of data at rates up to 300 megabits/second, which is 5,000 times faster than the standard 56K home computer modem.

| ITEM (3): TDRS Constellation - TDRS-I will help to replenish and maintain the space communications of the current F1-F7 fleet. TDRS-J will be added to the fleet in October 2002. Upon completion of on-orbit testing and acceptance, TDRS-l will be renamed TDRS-9 and relocated to its operational slot where it will provide improved communications and data relay services well into the 21st century.
