3rd-Generation TDRS Satellite to Launch
As a vital information pipeline for space-based research and exploration ambitions, the Tracking and Data Relay Satellites or TDRS constellation fulfills NASA's broadest communication demands.
Now into it's fourth operational decade, the TDRS legacy continue's to be communications excellence. The addition of the third generation of spacecraft will replenish the constellation and ensure that the critical lifeline of space-to-ground communication support will be available for many years to come. TDRS-K or TDRS-11 will launch January 29, 2013.
Before TDRS, NASA relied on a web of ground-based tracking and communication stations located around the globe. These ground stations used large antennas to receive early transmissions from space.
