Watch a Delta IV Heavy rocket blast off for National Reconnaissance
The United Launch Alliance Delta IV Heavy rocket will blast off of Space Launch Complex-37 at Cape Canaveral Space Force Station, Florida. The customer for this mission is the National Reconnaissance Office, but the payload is unknown, as the mission is classified. If the Delta IV Heavy rocket lifts off on December 10th, 6:15 PM EST as planned, this will be the 142nd mission that ULA has performed, and the 30th time the National Reconnaissance Office has purchased a ride on a ULA Rocket. This rocket uses Liquid Hydrogen and Liquid Oxygen as fuel, which enables the rocket to reduce pollution coming from itself.
As the payload/satellite aboard this rocket is classified, for the National Reconnaissance Office, we do not know much about it, other than it is going to orbit aboard the Delta IV Heavy Rocket.
The Delta IV Heavy rocket is the 2nd most powerful operational rocket in the world, right after Falcon Heavy, and Delta IV Heavy is also the biggest operational rocket in the world.
