'''TDRS-5''', known before launch as '''TDRS-E''', is an [[United States|American]] [[communications satellite]] which is operated by [[NASA]] as part of the [[Tracking and Data Relay Satellite System]]. It was constructed by [[TRW]] is based on a custom [[satellite bus]] which was used for all seven first generation TDRS satellites.<ref name="GSP">{{cite web|url=http://space.skyrocket.de/index_frame.htm?http://space.skyrocket.de/doc_sdat/tdrs-5.htm|title=TDRS 1, 2, 3, 4, 5, 6|publisher=Gunter's Space Page|first=Gunter|last=Krebs|accessdate=2009-08-02}}</ref>

It was launched aboard {{OV|104}} during the [[STS-43]] mission in August 1991. ''Atlantis'' launched from [[Kennedy Space Center Launch Complex 39|Launch Complex 39A]] at the [[Kennedy Space Center]] at 15:02:00 GMT (11:02 local time), on 2 August.<ref name="JSR">{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|publisher=Jonathan's Space Page|first=Jonathan|last=McDowell|accessdate=2009-08-02}}</ref> TDRS-E was deployed from ''Atlantis'' around six hours after launch, and was raised to [[geostationary orbit]] by means of an [[Inertial Upper Stage]]. It was the only TDRS satellite to be deployed from ''Atlantis''.<ref name="JSR"/>

The twin-stage solid-propellent Inertial Upper Stage made two burns. The first stage burn occurred shortly after deployment, from ''Atlantis'', and placed the satellite into a [[geosynchronous transfer orbit]]. Around six hours later, it reached [[apogee]], and the second stage fired, placing TDRS-E into geostationary orbit. At this point it received its operational designation, TDRS-5. It was placed at a position over the [[equator]], 174° West of the [[Greenwich Meridian]],<ref name="SFN-TDRSJ"/> from where it provides communications services to spacecraft in Earth orbit, including the [[Space Shuttle]] and [[International Space Station]]. Some of its transponders are operated by the [[Columbia Communications Corporation]].<ref>{{cite web|url=http://www.tbs-satellite.com/tse/online/sat_tdrs_5.html|title=TDRS 5|publisher=TSE|accessdate=2009-08-02}}</ref>
