Postponing launch to replace fairing pneumatic valve. It is dual redundant, but not worth taking a chance.

обратите внимание, заглючило не флайт прувен хардваре

A Falcon 9 rocket has unexpectedly appeared vertical at pad 39A as engineers replace a faulty valve on the payload fairing that will shield Bulgaria's first communications satellite during a delayed liftoff now set for Friday.

The Falcon 9 is without a payload fairing, but whether the rocket is on the pad for a second hotfire engine test or a fueling demonstration is unclear.

We have asked SpaceX for clarification on its plans for the rocket at pad 39A in the coming days.

SpaceX conducted a static hold-down engine firing of the Falcon 9 rocket slated to launch BulgariaSat 1 on Thursday, then returned the vehicle to the hangar at pad 39A for attachment of the satellite before SpaceX announced a four-day launch delay yesterday.

F9 at 39A now horizontal again following an overnight test opportunity. F9 at Vandy currently aiming for 1:30pm local time Static Fire test.

SpaceX testing Vandy Falcon 9 amid schedule realignment
June 20, 2017 by Chris Bergin



SpaceX is preparing to static fire test a Falcon 9 at the Vandenberg Air Force Base ahead of a mission to launch the next set of Iridium NEXT satellites. The test will set the stage for the potential of two launches within two days for SpaceX, as it realigns the launch date for the Falcon 9 that has already conducted a hot-fire test ahead of its BulgariaSat-1 mission.

Test, Test, Launch, Launch:

 Скрытый текст:

The previous plan was to launch the BulgariaSat-1 mission on Monday. However, an issue with a fairing valve resulted in SpaceX delaying the launch until NET (No Earlier Than) June 23.



The valve system - used to separate the two fairing halves that encapsulate and protect the payload during the initial phase - has redundancy built into the system. Elon Musk tweeted that it was "not worth taking a chance", thus the valve is being replaced inside the 39A Horizontal Integration Facility (HIF).

The Falcon 9 had returned to the HIF following a successful seven second Static Fire test of its nine Merlin 1D engines and was undergoing the stack integration flow ahead of rollout when the issue was noted as part of the routine pre-rollout checks.

Interestingly, a surprise rollout of what is understood to be the same Falcon 9 took place on Monday evening, again - as is now common practice - without the payload.

While the identity of the booster has not been confirmed, the Falcon 9 was not expected to conduct a second static fire, based on the lack of required notices for KSC workers, per roadblocks and safety precautions relating to such tests. Sources also stress the original Static Fire test was without issue and the vehicle had passed its Launch Readiness Review (LRR).

While unconfirmed by SpaceX, it is understood the vehicle is at the pad to aid the testing of ground hydraulics in the 39A Ground Support Equipment (GSE) system. This element of the GSE has required some periodical work since 39A was reactivated for use with SpaceX launches.



With the launch delayed while engineers replace the valve on the fairing, the opportunity to use the rocket sat on the TEL with nothing to do for several days may have initiated this mooted Pad GSE test.

Once the Falcon 9 is back in the HIF, the pre-launch mating flow will take place ahead of rollout back up the 39A ramp - this time as an integrated stack - for launch within a two-hour window that opens at 14:10 local time on Friday.

...

SpaceX has the ability to continue the flow towards launch, despite the schedule change with the BulgariSat-1 pre-launch flow, due to two separate launch teams for its two - currently active - launch sites.

SpaceX's mission control (MCC-X) in Hawthorne, California also holds the ability thanks to a recent configuration change that avoids any overlaps in procedures relating to the two individual missions taking place in close proximity.

These next two missions will set a record minimum gap between a pair of SpaceX launches, although due to the slip of the BulgariaSat-1 launch, a third closely schedule mission - with Intelsat 35e, which was scheduled to launch on July 1 - will obviously be pushed to the right.

Будут тестировать включение верхней ступени в апогее для свода ее с орбиты? А в пресс-ките об этом ни слова.

А где об этом слова?

А, запретная зона, да?

[Чебурашка]

Нихрена они себе запретную зону выделили. Больше Австралии по площади   
С севера на юг -  3333 км

Да. После NROL-76 следующий логичный шаг.

Чтото запретная зона не в тех широтах в которых пролегают геопереходные орбиты...

Может, ступень после схода еще довольно далеко в атмосфере пролетит?

Ну не часто что-то с геостационара падает...
А учитывая что они её более чем на полсуток резервируют - и в количестве витков не уверены.
Кстати, от второго пуска будет падать сюда же через сутки.
