Static fire tomorrow, August 22.

SpaceX still on track for an August 26 launch at 0050-0405 Local (Eastern). The only potential issue at this time is weather.

Static fire successful. Checking data.

One day launch slip to August 27. Nothing to do with the F9R Dev-1 issue at McGregor.

Falcon 9 / Asisat-6 Launch Operations Forecast -- Launch Window: 27 Aug 2014 / 0450 - 0805Z (0050 - 0405EDT) -

Forecast: Given the great uncertainty of the tropical system, which may still be near the Spaceport through mid- week, the primary 24-hour delay concerns remain Cumulus and Anvil clouds and Liftoff Winds.

Launch day probability of violating launch weather constraints: 40% Primary concern(s): Cumulus and Anvil Cloud Rules, Liftoff Winds

24-hour delay overall probability of violating weather constraints: 40% Primary concern(s): Cumulus and Anvil Cloud Rules, Liftoff Winds

Seems to be an abundance of caution. Launch Readiness Review went fine.

AFICT there was a hiccup last night that turned out to be nothing, but took time & effort to clear. Elon made the call to get a fresh start.

Guess: may go this weekend.

Postponed for a week or two to make sure all is well. Abundance of caution.

Within this we are told what happened to F9R Dev-1: a blocked sensor port.

Update on AsiaSat 6 Mission

"SpaceX has decided to postpone tomorrow's flight of AsiaSat 6. We are not aware of any issue with Falcon 9, nor the interfaces with the Spacecraft, but have decided to review all potential failure modes and contingencies again. We expect to complete this process in one to two weeks.

"The natural question is whether this is related to the test vehicle malfunction at our development facility in Texas last week. After a thorough review, we are confident that there is no direct link. Had the same blocked sensor port problem occurred with an operational Falcon 9, it would have been outvoted by several other sensors. That voting system was not present on the test vehicle.

"What we do want to triple-check is whether even highly improbable corner case scenarios have the optimal fault detection and recovery logic. This has already been reviewed by SpaceX and multiple outside agencies, so the most likely outcome is no change. If any changes are made, we will provide as much detail as is allowed under US law."

-- Elon Musk

The systems on the F9 continue to amaze me. The amount of redundancy along with its engine out capability and soon reusability is truly state of the art. I can't even imagine what capabilities it has that they aren't telling us about.

Falcon 9 uses voting systems like that for sensors (normal practice), each engines controller, the flight avionics on both stages (most birds only have avionics in the upper stage), and Dragons 18 computers.

What got me about the engine out was that it was totally autonomous - everything from engine shutdown to reconfiguring the flight plan. Then Dragon got to ISS 30 minutes early.

I bet the Galileo guys are wishing they'd booked an F9. :p

You'd never get ESA or Arianespace to say that, but Germany has contracted for Falcon 9 to launch 3 radar spysats.

OTOH, France is having a stroke over SpaceX, asking NASA to stop them from dumping cheap launchers on the market - as if NASA has any say in the matter.

Of course dumping means you're selling launchers below cost, but that's demonstrably not true. F9 is just carefully engineered for low costs in spite of its sophistication.

Arianespace is basically in the same position as US automakers when Toyota came out with the Corolla, Celica etc.

Actually Arianespace is in a worse position with ariane and soyuz...

And they know it. Nothing short of a crisis can get Arianespace to think about de-bureaucratizing. Aviation Week had a good article on it a few weeks ago.

@SCLAUNCH321: Official: the SPX launch is now on the range schedule. 9/6 0050-0404 and backup 9/7 same time. The WX does NOT look good for the wkd here.

The weather, terrestrial and space, isn't looking terribly good. There's been a solar event.

And Dragon CRS-4 is still on the board for the 19th.

Both the primary and secondary dates have slipped 1 day.

The reason seems to be the Sept. 1st M2 level solar coronal mass ejection (CME) that will hit Earth on Saturday. This would compromise telemetry, satellite links etc. Better to just let it pass.

F9 has been rolled out, but lightning may be an issue. Typical for Florida.

 Indeed it is :D

 

Launch in ~1.5 hours if weather clears. Lightning tower struck earlier, but no effect on rocket or satellite pic.twitter.com/AWdx9LsFZt
