New tentative launch date for TDRS-M
(27 Jul 2017) NASA has provided Boeing concurrence to remove and replace the Tracking and Data Relay Satellite's (TDRS-M) Omni S-band forward antenna.
Pending Eastern Range approval, NASA, Boeing, and United Launch Alliance (ULA) are now targeting 20 August for launch. A 40-minute launch window would open at 1156 UTC.
This new date allows for time to replace the antenna, which was damaged earlier this month while Boeing was conducting final spacecraft closeout activities at Astrotech Space Operations in Titusville, Florida. TDRS-M will launch atop a ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida.
