Starship's advantages over the N1 is that the Raptors can be put into static fire tests, both individual and group, and then later be used on actual launches, whereas the NK-15 engines of the N1 had to be replaced entirely once fired. There's no way of telling on the N1 which engine it uses is defectiveBut the circular arrangement and gigantic size of the Booster remembers me of the N1.
I really really hope the Raptors perform well.
While Super Heavy will have more engines than N1 (37-ish compared to 30 of N1), the former may perform much greatly than the latter, which was boomed four times. Therefore, I don't have to hear the stereotype "more engines more problems" anymore.Starship's advantages over the N1 is that the Raptors can be put into static fire tests, both individual and group, and then later be used on actual launches, whereas the NK-15 engines of the N1 had to be replaced entirely once fired.

Yes, not so easy to dock facing backwards. I could try an option to reverse the pitch and yaw rotation, and fwd/back and left/right translation RCS. Didn't the SpaceShuttle have something like that?Thanks for the update! It is much fun to fly!
This time I managed docking to the tanker in the double-launch scenario on the first try. Although with less than expected fuel remaining, which is probably due to my point-and-go docking approach.
Really challenging is that the RCS controls are mostly inverted when looking backwards while approaching the aft docking port of the tanker. This took my armchair piloting skills to test.
On the fuel payload I guess the tankers will just have bigger tanks, so the tanking will consume the remaining fuel, minus the fly-back reserve.
No way to control cockpit view of RCS visuals as far as I know - I guess the exhaust plume is just a bit smaller, or something.A few things:
-I am only seeing the RCS visuals from the external view now. Not from the main forward view anymore. Not sure if that is intentional?
-Dumping the 2nd stage fuel now also leads to zero RCS fuel, while you need some for the landing. So this has become a little harder to manage. Maybe implemend some lower limit to keep some fuel aboard?
-I also would like the option to have the trim controls reversed. I prefer pulling back on the stick (down arrow) to increase the AoA, like normal aircraft. I keep pressing the wrong buttons when controlling the trim.
Thanks for your efforts!
Hi Chris,Apparently the first booster will have 29 raptors, an extra one in the center. Later this will increase to 32. This can be done with a ring of 4 in the center, then rings of 8 and 20.
This is based on a thrust puck being seen at Boca Chica and an Elon tweet. He's also talking about increased thrust (7,500 t?) and a thrust to weight ratio of 1.5.
Just seen another ElonTweet, 3 in the center, then 9 and 20. The inner 12 gimbal. May be better to wait and see. Get the impression that 12 are used for the boostback.
thanks for the updates. I don't tweet or go to NSF much, so I miss these things. I'm having fun with reentry autopilot for the upper stage at the moment, booster updates are on the back-burner anyway. 32 engines, thrust/weight of 1.5 - monstrous!
"Monstrous" in a large way ;-)Monstrous in a good or bad way? After all, if humanity plans to send a human crew into space (for example, to Mars), then the spacecraft must be very powerful in order to overcome the force of gravity and gain sufficient speed to enter orbit and travel in space.
Sure pressing U should work? I don't notice anything happening. I don't see 'U' listed as a button on the HUD either. Any idea what I could do wrong maybe?You can even give my (very clunky) reentry autopilot a try - use new starship.dll in the attached .zip
Press U for reentry autopilot from 120km. (it does like to "overfly" target at the moment).
