  • They attempted to relight the booster, but only 1 of the 13 engines they wanted on actually started (2 others almost started but immediately failed). Their hope was to demonstrate in-space relight of the second stage engines, which is obviously a crucial demonstration for HLS and eventually going to the moon, but they never went for it. So far they have never demonstrated Raptor start in a vacuum and microgravity, which is a significantly different challenge to firing on the ground or even during re-entry as was the case for the booster due to propellant slosh and ullage considerations. In fact, we have seen them struggle with these issues in the earlier Starship solo tests, where the engines upon relight would eat backfill helium and eventually switch over to an engine-rich cycle :D. I’m sure they will figure it out but in space Raptor relights are far from the ‘same’ as what they have already done.









  • I had exactly the same thing, and would come to my senses (for lack of a better term) every so often and be genuinely confused where days or even weeks had gone. One thing that has been really helping me is writing all the little things down such as what I ate or learned in classes as you mentioned.

    I personally started using Logseq for this but basically any note taking application will do. The most important feature that I use is linking topics, for example I would mark a bullet point with #food and so on, which eventually organizes the thoughts automatically. It’s really nice to be able to just write and not even think about organizing it as that’s the computer’s job.
