Ground controllers report the satellite – part of a network providing high-data-rate communications to the International Space Station, Hubble Space Telescope, launch vehicles and a host of other spacecraft – is in good health at the start of a three-month checkout by its manufacturer, Boeing Space and Intelligence Systems of El Segundo, Calif. “TDRS-L and the entire TDRS fleet provide a vital service to America’s space program by supporting missions that range from Earth-observation to deep space discoveries,” said NASA Administrator Charles Bolden. The mission of the TDRS Project, established in 1973, is to support NASA’s space communications network. This network provides high data-rate communications. The TDRS fleet began operating during the space shuttle era with the launch of TDRS-1 in 1983. Of the 11 TDRS spacecraft placed in service to date, eight still are operational. TDRS-M, the next spacecraft in this series, is on track to be ready for launch in late 2015.
