NROL-108 MISSION

Brian (Ruibo) Wu

According to SpaceX, on Saturday, December 19 at 9:00 a.m. EST, Falcon 9 launched the NROL-108 mission from Launch Complex 39A (LC-39A) at Kennedy Space Center, Florida, completing SpaceX’s 26th and final mission of 2020.

Falcon 9’s first stage booster previously supported the launch of SpaceX’s 19th and 20th cargo resupply missions to the International Space Station, a Starlink mission, and the SAOCOM 1B mission. Following stage separation, SpaceX landed Falcon 9’s first stage on Landing Zone 1 at Cape Canaveral Space Force Station in Florida – the 70th landing for SpaceX.

Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9, and Falcon Heavy launch vehicles. Merlin engines use a rocket grade kerosene (RP-1) and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for recovery and reuse.

Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond. Falcon 9 is the world’s first orbital-class reusable rocket. Reusability allows SpaceX to refly the most expensive parts of the rocket, which in turn drives down the cost of space access.

Recently, SpaceX is planning to test its next-generation rocket, the Falcon Heavy. It is the most powerful operational rocket in the world by a factor of two. With the ability to lift into orbit nearly 64 metric tons (141,000 lb), the Falcon Heavy can carry more than twice the payload of the next closest operational vehicle, the Delta IV Heavy. Falcon Heavy is composed of three Falcon 9 nine-engine cores whose 27 Merlin engines together generate more than 5 million pounds of thrust at liftoff, equal to approximately eighteen 747 aircraft.
