A shurt sommary of the plans:
- a 20 km flight within 1-2 months with the Starship Mk 1
- Starship in orbit within a year
- Starships - laden with passengers, freight or fuel - will mate back-to-back in orbit, to transfer fuel
- BFR (the booster) will feature up to 37 Raptor engines, though as few as 25 to 31 could work. It will have six fixed landing legs, grid fins for control
- SpaceX will begin construction of Starship Mk 3 and Mk 4 in Boca Chica and Florida in the next months. 3 and 4 will be built with rings of stainless 301 steel, instead of sheets. When Mk 4 is ready, they'll build the first BFR booster.
- Musk said an aggressive testing schedule could allow for putting humans on the Starship as soon as 2020.
- I still have doubts regarding his sanity.
Well the NASA Administrator, just before the event, apparently posted a tweet which some read as meaning 'why the hell are you doing this when Crew Dragon is not ready yet?'
You can imagine the responses, mostly along the lines of 'how are YOUR programs doing for timescales and costs?'.
Musk himself pointed out that only some 5% of SpaceX resources are tied up with these test vehicles.
If insanity is doing the same thing again and again but expecting different results, you have to put the traditional space launch providers in that bracket and their government overseers.
Yes I know, 'Elon time' and all that, however it might be that we are so used to seeing the traditional ways with long timescales, overspends, often followed by cancellation, that Musk does seem a bit mad to us.
