After more than a month of delay, one of the largest missiles in the business is preparing to launch from Cape Canaveral, Florida on a national security mission for the US National Reconnaissance Office.
A United Launch Alliance Delta IV heavy rocket will launch a classified spy satellite into orbit as early as Wednesday evening. The launch was originally scheduled for August 26th but was scrubbed several times due to technical issues with equipment on the launch pad.
In the past week, the technicians had to solve a problem with the swing arm’s retraction system and then suffered delays due to the weather.
Delta IV Heavy has carried out other NGO missions and sent them tooon the way to survey our sun.
The lifting capacity of the Delta IV Heavy is second most important after that. It is similar to the Falcon Heavy, the main body of which is made up of its three core amplifiers.
Unlike SpaceX, ULA doesn’t try to land its delta boosters. Instead, they are consumed and fall into the Atlantic.
Any three-body heavy-lift missile launch is still a landmark, and ULA is broadcasting the launch live, which you can see via the feed here on this page.
Currently, the launch is scheduled for Wednesday at 8:54 p.m. (11:54 p.m. ET).
If you happen to be in Florida, the rocket will be visible from much of the state as it ascends towards orbit. This is evident from this graphic guide from the ULA.
