Launch postponed until 30th March... as static firing due today has been postponed until tomorrow
I know I'm new on here.... but I work for Airbus DS, and have friends on the satellite launch/LEOP teams.

Good morning, B-1021! Nice to see you again.

This first stage is not being reflown? SpaceX and SES are lying? I have seen concerns that heating during reentry has the possibility of weakening the aluminium structure of the tanks. Presumably SpaceX will have eliminated this and similar concerns during NDT. Also, reuse puts extra cycles on subsystems which are subject to a lot of stress and lifetime concerns. I'm mainly thinking of the helium system here - not sure if there are others. This is not to say I think this flight will fail, but I will be holding my breath more than normal until MECO and separation. Cheers, Martin

I guess we can class this as "documentation" 45th Space Wing updated their header (but forgot to tweet) Falcon 9 SES-10 launch now NET 30th.
Isn't just case of 6:00 pm ET = 5:00 pm EDT?

The following is probably a contradiction in terms, but I can't think of a better way to say it:It seems to me that there are new unknown unknowns with this launch.We're changing a key variable, so there's the potential for previously unknowable, synergistic (?) effects to wreak havoc with the launch. Just one of those things that we won't know until we try. Having the cojones to try it with a multi-million dollar payload is why I admire SpaceX so much.

In reading about re-use of a first stage, all I've seen are concerns about the engines, pumps, tanks, etc. ie the "guts" of the rocket. Was there any discussion about the actual structure of the metal tube that holds everything together?
