The launch of NROL-44 was stopped just three seconds before it was scheduled to take off from the Space Launch Complex-37 at Delta 4 Heavy Cape Canaveral.
WAS SHINGTON – The United States Alliance Alliance Delta He heavy rocket remains on the ground after being released on August 29th during the ignition sequence before the 29th Eastern Liftoff carrying a classified spy satellite of the National Rick onnansis Office Fis.
The launch of NROL-44 stopped three seconds before the rocket was to take off from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida.
The Delta 4 Heavy’s three engines appeared to be on fire, but were then automatically shut down by a hot fire. ULA CEO Tori Bruno said on Twitter that the cause “appears to be in the ground system.” He said the abortion system “works to protect the vehicle and payload.”
The ULA said in a statement that it was “reviewing all data and will determine the way forward.” Attempts to launch another will not take place for at least seven days.
This was the third attempt to launch several days after the two scrubs – one on August 26 due to a customer request and one on Aug 27. Due to a technical problem with the ground pneumatics control system.
The launch of the 29 Aug Gust was originally scheduled for 2:04 a.m., but was delayed by a thermal discrepancy due to the expected temperature in one of the rocket parts.
