SpaceX F9 - TESS - SLC-40

[mongo]

Aargh. Scrubbed for the day per Chris G. with NSF. He goes on to tweet that it is likely a 48 hour scrub. So maybe Wednesday.

This is when we really need a 'dislike' option...

Is there a support crew on a ship out there with OCISLY? If so, do they just hang out for a couple days or make the 200 mile trip back?

I was in route to playlanda beach. Got scrub notice while supercharging at Port Orange. I'm in Fla in Jacksonville for the week but not sure if I can make it back down wednesday however going to try like the dickins!

90% go on weather for Wednesday.

If you want a place to crash, pm me. I’m in Palm Bay

Is the need for “additional GNC analysis” due to the somewhat unusual nature, at least for SpaceX, of the TESS orbit?

That was my takeaway.

Here it is again:

Will be tuning in this afternoon here. Boy only a 30-second launch window.

Only? That's like 30 seconds more than an instantaneous window.

Hey thanks for the offer! Unfortunately my problem is with work. Have prior commitments in Jacksonville today. Now if they push to Thursday I expect I can make it.

Thanks again

I'd say 29 seconds. I gotta believe they have more than 500ms slop in an instantaneous launch. I mean they advertise it as happening at hour:minute:second but they don't specify tenths of a second or milliseconds (at least not publicly).

I do wonder what they consider the margin of error on "instantaneous" or if they even try to get it to sub second precision.

Yeah, seems like there would be 'some' adjustment they could make post launch, but that would require a dog leg maneuver which the SpaceX nav system might not do yet...

Hans spoke about the 30 second launch window in the pre-launch NASA briefing. It is effectively an instantaneous launch. It would only help in a certain rare situation, which was mentioned.
NASA TV is on:

Webcast is live

 

[Cosmacelf]

1 minute to launch...

 

[Cosmacelf]

Launch successful, first stage capture on Of Course I Still Love You successful, stage 2 is in 35 minute coast phase now. All looks great.

Booooorinnnnng.

 

[ItsNotAboutTheMoney]

Booooorinnnnng.

Boooring, booring SpaceX!

Don't miss to watch the replay of NASA's webcast. Their cameras are really good and most of their shots are from ground which I think is way cooler than the shots from the rocket.
