Everyday Astronaut | Watch NASA fire up SLS for the first time! @EverydayAstronaut | Uploaded January 2021 | Updated October 2024, 1 week ago.
NASA will be putting their super heavy lift rocket, the SLS [Space Launch System], through the ultimate test. They will fill the tanks with LOx and LH2 and then light the four RS25 engines for a 8 minute full duration burn. It will not leave the pad, which means we will get 8 full minutes of awesome engine sounds.
