CAPE CANAVERAL, Fla .– United Launch Alliance (ULA) interrupted launch of the Atlas V rocket today (May 17) due to problems with the rocket’s liquid oxygen system.
ULA targeted the planned backup efforts on Tuesday afternoon (May 18), with an overhaul scheduled at 1:31 PM EDT (1731 GMT).
The two-stage rocket is scheduled to blast off Space Launch Complex 41 here at Cape Canaveral Space Force Station in Florida at 1:42 p.m. EDT (1742 GMT) on Monday (May 17). Missile warnings for the US Space Force

Determine the infrared system on space Geosynchronous Earth Orbit Flight 5 (SBIRS Geo-5) This mission marks the first ULA launch in 2021, however the company was forced to move the rollback 24 hours due to the system with a ground system at its launch base.
The official scrub came after the launch staff moved the T-0 backward within seven minutes as part of a maneuver to avoid a collision. This type of maneuver is meant to avoid collisions with objects located in space. (ULA officials did not specify which objects they attempted to avoid)
Shortly after that delay, the team detected a malfunction during the upper stage liquid oxygen operation. Engineers were sent to Launch Pad but were unable to fix the problem to make it debut during Monday’s planned 40-minute launch time frame.
The release of ULA #AtlasV undertaking the #SBIRS GEO Flight 5 mission for @SpaceForceDOD @USSF_SMC has been polished. During the Centaur Liquid Oxygen (LOX) operation, the team identified an unusual, irreversible system response within the May 17, 2021 launch window.
The SBIRS Geo-5 satellite was built by Lockheed Martin for $ 1 billion and, according to military officials, can detect and track the plumes emitted by ballistic missiles around the world with the help of infrared sensors. Its capabilities will help the United States and its allied forces prepare for impending attacks, officials said.
The satellite is wrapped in a 13.12 ft (4 m) diameter fairing adorned with the mission’s logo – a red and blue emblem depicting an eagle holding a missile in its claws with the Earth in its background.
The mission marks the fifth SBIRS satellite to launch, with one remaining to fill the military’s planned constellation.
Weather forecasters forecast a 90% chance of favorable conditions for the SBIRS Geo-5 overhaul by Monday afternoon, with the only cause of concern being the cumulus clouds. Weather conditions for Tuesday’s launch were slightly worse, with an 80% chance that the weather would be fine.
