Watch ULA launch the world’s largest rocket, the Delta IV Heavy!

United Launch Alliance will be launching another satellite for the National Reconnaissance Office (NRO). The NRO has a contract with ULA to fly their NROL satellites on Delta IV Heavy rockets. ULA previously launched the NROL-44 mission on a Delta IV Heavy, the 12th overall launch of that rocket. NROL-82 will be the 13th launch of a Delta IV Heavy, leaving only three more planned launches for the expendable launch system, all for the NRO. Want to learn more about today’s launch?
