Video: TDRS-M takes flight atop Atlas 5

The last of NASA’s current-generation tracking and data relay satellites designed to link mission control with the International Space Station has been assigned for launch on a United Launch Alliance Atlas 5 rocket in October 2017, officials announced Friday.

The last Delta 4 launcher to fly in a single-core configuration rumbled into space Thursday morning from Cape Canaveral with a GPS navigation satellite, leaving United Launch Alliance with five more Delta 4-Heavy missions on contract through late 2023 before the Delta rocket family retires from service.

The 377th Delta rocket begins its journey to space carrying a military communications satellite funded by Canada, Denmark, the Netherlands, Luxembourg and New Zealand in a deal that gives the allies access to the U.S. military’s worldwide Wideband Global SATCOM system.
