United Launch Alliance's (ULA) last Delta rocket is scheduled to launch tomorrow (March 29) at 1:37pm ET (5:37pm GMT) on a secret mission for the US National Reconnaissance Office (NRO) – and you can watch it live here .
The launch ends 64 years of the Delta rocket fleet, which was designed to lift large payloads into space. The Delta IV Heavy rocket, the 16th of its type to launch since 2004, will carry a secret cargo when it lifts off for the final time from Space Launch Complex-37 at Cape Canaveral Space Force Station in Florida.
ULA has not revealed the nature of the payload being launched into space, but it likely consists of an advanced satellite, according to our sister site Live Science. Space.com website. The NRO is an agency of the US Department of Defense charged with designing and operating surveillance satellites, and it rarely announces the nature and purpose of its reconnaissance systems to the public.

It is uncertain whether the Delta rocket will actually lift off at the newly announced time, as ground winds and cumulus clouds have created unfavorable conditions, already leading to delays. The 45th Weather Squadron expects a 30% chance of weather settling enough for a launch on Thursday, and a 60% chance of favorable conditions on Friday (March 29), according to Space flight now.
Ground winds are particularly concerning, as there is a risk of the rocket hitting the launch tower, ULA President and CEO Torey Bruno said during a news conference.
“It depends on the angle of the wind,” Bruno said. “We can launch within a very narrow moment of time. So, if the winds die down, even if just for a few minutes… we will launch within that window.”
The Delta IV Heavy rocket is not the only rocket to reach the end of its career, as ULA also plans to retire the Atlas 5. The Space Launch Company is making way for its new Vulcan Centaur rocket, which The first controversial mission – Sending Astrobotic Peregrine's ill-fated lunar lander towards the moon – Launched in early January.
