For maximum viewing effect, X2 multiplier reading glasses.

Right. Those particular cows are for .. something else. Someplace else, to be precise. *cough* ColonyOne *cough* :shifty:

We've got a launch window: 24 February, 18:46 - 20:23 EST [23:46 - 01:23 UTC]

 

 

Also:

A SpaceX official said the company still plans to attempt to land the first stage after the SES 9 launch, but profile change means there will be a lower chance of recovering it. So this probably means ASDS will be in place and they will try to land it but the chances of recovery are low due to fuel and trajectory...

SpaceX aims for drone ship landing after Feb. 24 Falcon 9 launch

 

Quote

The Air Force’s 45th Space Wing has formally approved SpaceX’s request to launch a Falcon 9 rocket and commercial communications satellite on Feb. 24.

The launch window opens at 6:46 p.m. and extends to 8:24 p.m.

The launch will be SpaceX’s first of the year from Cape Canaveral Air Force Station and second overall, following one last month from California.

Due to delays in its launch schedule, SpaceX has agreed to lift the SES-9 satellite to a higher orbit than originally planned to put it on a faster path to its operational orbit more than 22,000 miles over the equator.

With little fuel to spare, SpaceX won’t attempt to land the Falcon 9 booster back on shore like it did — successfully — on Dec. 21.

But the company is expected to try to land the rocket stage on an ocean platform, even though the odds of success are low because of the higher flight and low fuel margin.

SpaceX Falcon 9 preparing for Static Fire ahead of SES-9 launch

 

Quote

SpaceX’s Falcon 9 rocket is set for her Static Fire test on Monday, a dress rehearsal milestone ahead of Wednesday’s launch of the SES-9 satellite. The test is taking place at SLC-40, at the same time as work begins at LC-39A to remove the Shuttle-era Rotating Service Structure (RSS) from the site of future SpaceX launches.

 

SES-9:

The Static Fire test validates the health of the launch vehicle, allowing for SpaceX management to approve the final flow to launch day.

 

Numerous requirements have to be successfully proven via such a test, such as the engine ignition and shut down commands, which have to operate as designed, and that the Merlin 1D engines perform properly during start-up.

 

It also serves as a full dress rehearsal for the launch team and will provide another test of SpaceX’s recent upgrade to a supercooled propellant pad systems that resulted in a number of challenges ahead of its debut use during the OG-2 launch.

 

Once the required engine and vehicle data has been collected, detanking operations will follow, before the rocket is lowered onto the Transporter Erector (TE) and rolled back to the hanger.

 

The Static Fire’s data review will be fed into the Launch Readiness Review (LRR) – a key meeting that will ultimately confirm the launch date.

 

The first attempt is currently scheduled for Wednesday, within a window that ranges from 18:46 to 20:23 Eastern. A second opportunity is available on Thursday, within the same launch window.

 

The mission is tasked with lofting the SES-9 spacecraft en route to its orbital slot of 108.2° E. This satellite has been patiently waiting its turn for a ride into space after it was initially set to ride as the Return To Flight mission last year.

 

The satellite will provide incremental – as well as replacement capacity – to the well-established slot over Asia, where it will be co-located with the existing satellites.

 

Built by Boeing, the spacecraft is based on the BSS-702HP bus and has a launch mass of 5,330 kg.
