Static fire moved to Sunday.

 

Delayed by the Delta IV Heavy scrub. NROL didn't feel comfortable with their $billion bird being on the pad while another rocket was firing several miles away. 

If I remember correctly, SpaceX had this booked, prior to ULA wanting the Thursday launch (scrub). The earlier original launch date cancellation was  from NRO.

 

Thursday scrub then causes a delay with SpaceX, then this silliness....

 

 NRO and ULA both caused delays to SpaceX by trying to fit into a one day slot.

NRO made the call.

True, but they chose the launch day after NRO delayed the initial launch date.

Have not been able to see any activity for static fire, assume one for Monday I imagine. With a Wednesday launch, should be ample time if no bugs found. News has been lacking with this static fire....guess I will do some "barge stalking" instead...:D

Static fire completed yesterday. It went off so fast the media missed it and SpaceX PR didn't tweet.

 

Weather: 80%

Falcon 9 checks off Static Fire for third GEO Satellite Launch in a Row

 

Quote

A SpaceX Falcon 9 rocket hot fired its engines on Sunday to set up for the vehicle’s third commercial communications satellite launch in the space of just under six weeks.

 

Aiming for liftoff on Wednesday, Falcon 9 will be carrying two stacked spacecraft built by Boeing Space Systems for satellite operators Eutelsat Americas and Asia Broadcast Satellite (ABS). This marks the second dual-payload launch for the two companies after the Eutelsat 115 West B and ABS 3A satellites headed into orbit aboard a Falcon 9 v1.1 rocket in March of 2015.

 

With a combined payload mass of around 4,200 Kilograms and the increased power of the Falcon 9 FT launch vehicle, this mission will leave sufficient propellant margin on the rocket’s first stage for SpaceX’s next high-energy return attempt.

 

The two most recent sea-based landings of the booster atop the Autonomous Spaceport Drone Ship have been a surprise as the vehicles were not expected to make it through a challenging re-entry environment. This mission will see similar conditions at re-entry, but previous flights have shown Falcon 9 is quite resilient – though it remains to be seen whether Falcon 9 can stand its fourth Drone Ship landing in a row.

These static fires are going away before too long. They'll roll out, erect the launcher, gas up and launch in an hour or so.

 

Run 'n Gun.

 

USAF has wanted rapid response launch for decades, so once they can also integrate quickly USAF will be smiling. I would imagine Firefly etc. will be encouraged to do this for smaller payloads as well.

I'm more comfortable with them doing the static fires, simply as a diagnostic pre-flight procedure before launch. It's 10 seconds of extra precaution, wait ten minutes to read green, top off the tanks and reset the system, and then launch. Certainly no harm in that? :D

Always seems to display that way for me :pinch:.  Always thought it was MS edge or something doing that.
