This time with correct units! [Edit: NOT]
Some things that stand out to me:
- Acceleration from liftoff until around 1:00 is pretty much flat. I know rockets throttle down for Max Q but I didn’t realize it would be that much.
- Speaking of Max Q, it was announced on stream around the 1 minute mark and we can see that the vehicle quickly begins to accelerate afterwards. That being said, it was planned to happen at around 0:52, according to SpaceX’s press release. I wonder why (if) it came late.
- You can see just before the 2 minute mark when the first stage throttles back to limit acceleration on the structure as the vehicle gets lighter. Notice that it still rises though!
- When the Starship engines light, it seems to have a similar TWR to the booster at liftoff. I wonder what it will be like when it starts carrying payloads!
- As I mentioned in my previous post, you can clearly see at the 7:30 mark that the acceleration suddenly flattens. Could certainly have been planned, but I’m starting to suspect a malfunction.

Looks like you updated the numbers but not the unit label. It still says km/s^2, which is a bit nuts. 35 m/s^2 is 0-80mph in 1s which is obviously fast but not destroy-everything fast like 0-80,000mph in 1s.
Thank you! I’m somewhat embarrassed, but these silly mistakes really show why I did not end up in a field that requires any kind of serious math. I just do this for fun and, thanks to people like you, am learning as I go along!
