Weekly Space Report: Details from Starship Static Fire, SpaceX Sells Offshore Oil Rigs, New Glenn Wins NASA Launch Contract, Now Progress Springs a Leak
Any news on the concrete erosion problem with the 33 engine test?
I haven’t heard anything. The 31 engine static fire (33 engines were installed, but one was disabled before firing and another shut down after ignition) was conducted at 50% of full thrust. Elon Musk has said that the orbital flight test will use 90% thrust at liftoff (presumably reduced because there will be no payload).
They are apparently installing a water deluge system on the orbit launch mount, but I haven’t heard whether they expect that to be ready for the orbital flight test.
