Well that was an anti-climax. Will be asking sources what happened.

Likely to be a little bit before there's much to report on...wonder if SpaceX will do an webcast announcement or not.

That came late too, as I had a "no issues" not long after prop loading was complete. Working it.

they use helium for turbopump spin up, right?  Or was this for the helium tanks for the legs?

CRS-3 Update
Today’s launch has been scrubbed due to a Helium leak on Falcon 9’s first stage. A fix will be implemented by the next launch opportunity on Friday April 18, though weather on that date isn’t ideal. Check back here for updates.

What's the next launch date if Friday is scrubbed because of the weather?

It's every 4 days, isn't it?  So 4/22?

I believe so too. Will check.

Ok, so this thread is no longer a live thread. We'll set up a new one for the next attempt. However, posts must be specific to this scrub. If not, use the discussion threads.

Fuel pressurization.  Secondary function is leg deployment.

And stage separation, which happens to be today's culprit, I'm hearing.

Update thread, people.

Expressions of dismay, questioning people's sources, refuting reports, etc... all off topic.

Do we have any updates on whether the leak was on GSE side or in/on the rocket itself?
LEO is the ocean, not an island (let alone a continent). We create cruise liners to ride the oceans, not artificial islands in the middle of them. We need a physical place, which has physical resources, to make our future out there.

Long look ahead to Friday weather posted by the 45th Weather Squadron:
http://www.patrick.af.mil/shared/media/document/AFD-070716-028.pdf

Quote
Synoptic Discussion:Weather will begin to deteriorate Tuesday as a cold frontal system moves into the area with widespread clouds, rain and isolated thunderstorms. There is also a slight chance for hail and severe winds. The front should clear south of the Spaceport on Wednesday, allowing clouds to diminish.  Temperatures will struggle to reach the mid 70’s as strong northeasterly surface winds remain through Thursday. On Friday, models indicate a wave developing in the Gulf of Mexico and moving over Central Florida. Thick cloud cover and periods of rain and isolated thunderstorms are typical with these systems.  Maximum upper level winds will be 70 knots from the west-northwest at 43,000 feet.

Launch day probability of violating launch weather constraints:  60%
Primary concern(s)
:  Thick Cloud Rule, Lightning Rule, Flight Through Precipitation
