Agreed, but aspirational is a motivational goal for his team, not a statement that they will fly by such and such a date. Quote Link to comment Share on other sites More sharing options...

CatastrophicFailure Posted May 1, 2020 Share Posted May 1, 2020 So this is interesting... Great, big, high mounted lights do make a certain amount of sense, and I recall Musk saying earlier the plan was to hoverslam and then (slowly) drop the last few meters. Hmmm.... ...tho personally I’m hoping for ice cream dispensers now... Quote Link to comment Share on other sites More sharing options...

You would be flying that thing with a radar. Or rather it would be flying itself. Edited May 1, 2020 by Wjolcz Quote Link to comment Share on other sites More sharing options...

RealKerbal3x Posted May 1, 2020 Share Posted May 1, 2020 Interesting, I wonder how they plan to fly the thing with one off-centre engine. Quote Link to comment Share on other sites More sharing options...
RCgothic Posted May 1, 2020 Share Posted May 1, 2020 It can gimbal through the centre of mass, should be fine. Quote Link to comment Share on other sites More sharing options...

What about the offcenter gimbal induced rotation though? I doubt current RCS thrusters are powerful enough to compensate (if SN4 has any at all?).

RCgothic Posted May 1, 2020 Share Posted May 1, 2020 (edited) There won't be any (unintended) rotation as the engine points through the CoM. There will probably be a slight horizontal kick as SN4 takes off and lands, but should be well within tolerance.

cubinator Posted May 1, 2020 Share Posted May 1, 2020 Looks like the ISS and Dragon will be visible over the US in the evening after the launch. Perhaps they should encourage people to go outside and watch that, given that watching the launch in person is not such a good idea. Quote Link to comment Share on other sites More sharing options...
