NASA Associate Administrator of the Human Exploration and Operations Kathy Lueders gave a Twitter update on the progress SpaceX is making in dealing with an anomaly during a recent launch. Her tweets are below.
We are making a lot of good progress with @SpaceX on engine testing to better understand the unexpected behavior observed during a recent non-NASA launch.
It’s too early to report findings at this point, as @SpaceX continues testing to validate what’s believed to be the most credible cause.
Based on our current analysis, @SpaceX is replacing one Merlin engine on the Sentinel-6 Michael Freilich launch vehicle and one engine for Crew-1 rocket that displayed similar early-start behavior during testing.
We are still targeting the Sentinel-6 launch for Nov. 10 from Vandenberg Air Force Base as we expect to complete forward work in time.
We are also still working towards a mid-November launch for Crew-1. We will want a few days between Sentinel-6 and Crew-1 to complete data reviews and check performance. Most importantly, we will fly all our missions when we are ready.
Crew-1 mission will be the first commercial flight of the Crew Dragon vehicle to the International Space Station.
