The infrared payload on the SBIRS satellites can detect the hot exhaust plumes from missile launches around the world, giving U.S. and allied forces early warning of an attack. Heading for an orbital perch more than 22,000 miles (nearly 36,000 kilometers) over the equator, the SBIRS GEO 5 satellite launched Monday debuted new improvements over the previous block of four SBIRS satellites.
“SBIRS capability really remains an on-orbit guardian for us against global ballistic missile threats,” said Col. Erin Gulden, mission director for the SBIRS GEO 5 mission at the Space Force’s Space and Missile Systems Center, which manages procurement of military satellites. (...)
The Centaur upper stage then released two suitcase-size secondary “Technology Demonstration Orbiter” payloads named TDO 3 and TDO 4 for the U.S. Air Force Academy. Military officials said the two small satellites carry experimental payloads, but they did not disclose any additional details. (...)

Two earlier missions with similar designators, TDO-1 and TDO-2, rode aboard Atlas Vs in August 2019 and March 2020, alongside the second-to-last and last Advanced Extremely High Frequency (AEHF) military communications satellites. The two missions focused upon a range of orbital debris tracking and space domain awareness functionality tasks. (...)

(...) Gary Wentz, ULA’s vice president of government and commercial programs, told reporters the RL10 C-1-1 is a higher performance engine than the RL10 C-1 flown in previous Atlas 5 missions. He said this was the first operational mission for the RL-10 C-1-1 that has a 3D-printed core main injector. The engine will power the upper stage of ULA’s next-generation rocket, the Vulcan Centaur.
This was the first launch of 2021 for the Atlas 5 and the 87th overall. Atlas 5 launched the first four SBIRS GEO satellites in 2011, 2013, 2017 and 2018. SBIRS GEO-6 also will launch on an Atlas 5 rocket.
Wentz said the company is building a larger aft bulkhead for Vulcan’s Centaur 5 upper stage so it’s able to carry more secondary payloads. (...)
