The launch of the off-spin satellite of the US spy has been restored again, this time no earlier than January 6th, according to the Alliance for Unified Warfare.
A ULA Delta IV heavy rocket was scheduled for an extraordinary satellite mission, called NROL-71, on Sunday (December 30th) from the California Vancouver Air Base. The launch has been delayed several times due to missile problems, recently on December 19, due to suspicion of leakage of hydrogen to booster.
"The United Delta Delta IV Task Force to join the NROL-71 mission will start no earlier than Sunday, January 6, 2019," Ula officials said in a statement. "The mission will start from the Spacecraft Complex 6 in the Vandenberg Base Force in California."
The ULA's attempts to start the NROL-71 mission on 7 and 8 December were delayed due to technical problems. The December 18 attempt was prevented by strong winds, which led to purification on December 19.
