Due to equipment failures and bad weather, the joint launch Alliance (ULA) plans to launch its most powerful rocket from Cape Canaveral, Florida, which will launch a classified spy satellite for the U.S. National Reconnaissance Office (NRO). It is reported that a full month after the first launch of the rocket, the mission is finally ready to fly. The first launch failed three seconds before launch. < / P > < p > the rocket responsible for the ula mission is delta IV heavy, a huge launch vehicle with additional thrust provided by three bundled rocket cores. Although it is less powerful than SpaceX’s Falcon heavy rocket, it is still one of the most powerful rockets in the world. Ula doesn’t launch delta IV heavy very often because it’s an expensive vehicle, but the company will use it to launch large, heavy satellites into ultra-high orbit. It is understood that the payload of this rocket is nrol-44. Like all NRO missions, its purpose is to be kept secret. The office only disclosed that nro-44 supports NRO’s overall national security mission and provides intelligence data to senior U.S. policy makers, intelligence agencies and the Department of defense. Up to now, ula has performed 29 missions for NRO, many of which use delta IV heavy. < / P > < p > it is reported that the delta IV heavy rocket will be launched from the ula launch site at Cape Canaveral Air Force Base at 11:54 p.m. ET on Tuesday. Ula’s launch blog will start at 3:15 p.m. Eastern time and live webcast will start at 11:34 p.m. Global Tech
