The Webcast still says will start at 6:40PM.

It would be really nice if they included a time zone.

How come the launch window is so long ?

Given that it is a remote sensing satellite and a small one, they probably do not care about the initial orbit ground track, only about inclination and apogee/perigee. It's not like they have to actually rendezvous with another craft.

I read spaceX is using pneumatic separation systems.
Is this technology used on another launch vehicle ?

In their previous flight, they have not yet tested separation between s/c and upper stage. Is this again a pneumatic system ?

Because there are no requirements constraining it

Flight 2 did eject the payload after the second stage shutdown. Just not at orbital velocity.

When is this thing taking off? How many hours from now to avoid confusion with time zones please.

jhoblik · « **Reply #352 on:** 07/13/2009 11:19 pm »

No it says 4:15pm PST. Maybe delay was because tracking requirement for Space shuttle

Nasa is providing the ground tracking radars for SpaceX ?

T-0 could be less than one hour from now.

EDIT: ... or could be more than three hours from now.

I spy countdown clock. T-2:14:00

ST47 · « **Reply #357 on:** 07/14/2009 12:21 am »

Does that mean we're really launching then (which would coincide with 730 pm pdt) or are there built-in holds? Do we get a launch timeline for the falcon I or is it too new for fancy PR info?

Jim · « **Reply #358 on:** 07/14/2009 12:25 am »

yes and no and yes

Swatch · « **Reply #359 on:** 07/14/2009 12:42 am »

Jim, I think there were 4 questions there....

(but only 3 question marks)

Where are you guys seeing the countdown clock?
