Final Green Run Test, Take 2

On Thursday, March 18, 2021 from 1500 – 1700 EDT (2000-2200 UTC) NASA will lighting up four Aerojet Rocketdyne RS-25s.

On the day of the test, engineers will turn on all the SLS’s systems and fuel up more than 700,000 gallons of cryogenic propellant into the tanks. They will then ignite the rocket’s four engines at once to simulate the core stage’s operation during launch. This will provide 1.6 million pounds of thrust.

The SLS being tested will launch for the Artemis I mission. Learn more about the testing and missions in our NASA SLS articles.
