Falcon 9 Rocket Grounded After Satellite Mishap
Context
The US Federal Aviation Administration (FAA) has grounded SpaceX’s Falcon 9 rocket following a recent failure (first since 2015). The incident involved the rocket's upper stage engine malfunction, which left 20 Starlink internet satellites in an unusable low orbit.
What is Falcon 9?
- Falcon 9 is a reusable rocket developed by SpaceX, powered by liquid oxygen and rocket grade kerosene (RP- 1).
- It consists of two stages:
- the reusable first stage with nine Merlin engines
- the second stage with a single Merlin engine
- The rocket's first stage is powered by nine Merlin engines, while the second stage uses a single Merlin Vacuum engine optimized for use in the vacuum of space.
- It is capable of transporting payloads and crew to low Earth orbit and beyond. Falcon 9 is the only U.S. rocket capable of sending NASA crews to the International Space Station.
- Payload Capacity: Falcon 9 can transport payloads weighing up to 22,800 kilograms (50,300 pounds) to low Earth orbit (LEO) and up to 8,300 kilograms (18,300 pounds) to geostationary transfer orbit (GTO).
- Versatility: It is used for a variety of missions including satellite deployment, cargo resupply to the International Space Station (ISS), and crewed missions under NASA's Commercial Crew Program.
- The workhorse rocket has launched more than 350 timessince its debut in June 2010.
