CAPE CANAVERAL, Fla. – During a news conference at NASA's Kennedy Space Center in Florida, agency and contractor officials discussed preparations for the launch of NASA's Tracking and Data Relay Satellite, or TDRS-L, spacecraft. Participants included Badri Younes, deputy associate administrator, Space Communications and Navigation SCaN NASA Human Exploration and Operations Mission Directorate at NASA Headquarters in Washington D.C. The TDRS-L spacecraft is the second of three new satellites designed to ensure vital operational continuity for NASA by expanding the lifespan of the Tracking and Data Relay Satellite System TDRSS fleet, which consists of eight satellites in geosynchronous orbit. The spacecraft provide tracking, telemetry, command and high bandwidth data return services for numerous science and human exploration missions orbiting Earth. These include NASA's Hubble Space Telescope and the International Space Station. TDRS-L has a high-performance solar panel designed for more spacecraft power to meet the growing S-band communications requirements. TDRSS is one of NASA Space Communication and Navigation’s SCaN three networks providing space communications to NASA’s missions.

S70-19764 (18 Sept. 1970) --- Astronauts Alan B. Shepard Jr. (right), commander, and Edgar D. Mitchell, lunar module pilot, are suited up for a manned altitude run in the Apollo 14 Lunar Module. The manned run in a vacuum chamber of the Manned Spacecraft Operations Building was conducted to validate the LM's communications and guidance and navigation systems. Apollo 14 is scheduled for launch from Cape Kennedy on Jan. 31, 1971, on a lunar exploration mission which is to carry Shepard and Mitchell down to the moon's rugged Fra Maura highlands region. Astronaut Stuart A. Roosa, command module pilot, will remain with the Apollo 14 Command and Service Modules in lunar orbit while the other two astronauts explore the moon.

Launch was at 9:33 p.m. EST Jan. 23 during a 40-minute launch window. The TDRS-L spacecraft is the second of three new satellites designed to ensure vital operational continuity for NASA by expanding the lifespan of the Tracking and Data Relay Satellite System TDRSS fleet, which consists of eight satellites in geosynchronous orbit. The spacecraft provide tracking, telemetry, command and high-bandwidth data return services for numerous science and human exploration missions orbiting Earth. These include NASA's Hubble Space Telescope and the International Space Station. TDRS-L has a high-performance solar panel designed for more spacecraft power to meet the growing S-band communications requirements. TDRSS is one of three NASA Space Communication and Navigation SCaN networks providing space communications to NASA’s missions. For more information more about TDRS-L, visit http://www.nasa.gov/tdrs.
