After scrubbing yesterday's countdown to analyze a minor glitch with the Falcon 9's upper stage engine actuator, SpaceX apparently plans to try again to launch the rocket with a Thai communications satellite today at 5:39 p.m. EDT (2139 GMT).
The company has not officially confirmed a launch attempt will occur today, but all indications so far are the countdown is underway. There is a two-hour launch window available this evening.

Прогноз погоды не очень хороший

The weather forecast is significantly worse Friday.
Whereas mostly sunny skies were over the Cape Canaveral spaceport Thursday, overcast conditions and scattered showers are in the outlook Friday, when there is a 60 percent chance weather will violate one of the Falcon 9's launch rules.

Погода может улучшиться в субботу:

A slight improvement may be in the offing Saturday, when there is a 50 percent chance of acceptable weather conditions for a launch.

погода - 60%

Сегодня прогноз очень скачет. Предварительный на сегодня был 70%, с утра - 40%, сейчас 60%
Могут и отменить по погоде... :cry:

The U.S. Air Force Eastern Range has finished hold-fire checks with the Falcon 9 rocket.
The Falcon 9 countdown is significantly changed with the upgraded version of the rocket.
While radio checks and flight termination system tests complete, fueling of the rocket with its propellant mixture of RP-1 rocket-grade kerosene and liquid oxygen will not begin until about a half-hour before the launch, instead of at about T-minus 3 hours on earlier Falcon 9s.
The upgraded Falcon 9 consumes a chilled propellant mix that allows engineers to load additional fuel into the rocket. The cryogenic liquid oxygen is chilled closer to its freezing point, from minus 298 degrees Fahrenheit to minus 340 degrees, while the RP-1 fuel is cooled from a more standard room temperature of about 70 degrees Fahrenheit to 20 degrees, according to SpaceX founder Elon Musk.
The change essentially permits the volume of the Falcon 9 fuel tanks, which are also slightly enlarged on this launch, to hold more mass of propellant, giving the rocket more performance.
The Merlin engines on the first and second stages will also produce more thrust. At liftoff, the nine-engine first stage will generate 1.5 million pounds of thrust, up from 1.3 million force-pounds on the Falcon 9's previous version.
The second stage engine is also modified with a bigger nozzle, and the stage separation system includes a new pusher device to help guide the first stage as it is jettisoned, ensuring no recontact.
Taken together, the modifications allow the Falcon 9 to carry heavier satellites into orbit and still attempt booster landings on the coast or on an ocean-going barge. This afternoon's launch will target a landing on a barge 420 miles (680 kilometers) offshore in the Atlantic Ocean.

SpaceX will attempt to land the 156-foot-tall first stage of the Falcon 9 rocket downrange aboard a recovery vessel, extending the company's experiments with rocket re-entry and reusability.
The drone ship, christened "Of Course I Still Love You," is positioned about 420 miles (680 kilometers) east of Cape Canaveral in the Atlantic Ocean.
SpaceX says a successful landing is challenging on this mission because of the higher speed the rocket needs to reach with the Thaicom 8 communications satellite, which is heading toward an orbit with a high point thousands of miles above Earth.
"Following stage separation, the first stage of Falcon 9 will attempt an experimental landing on the 'Of Course I Still Love You' droneship," SpaceX said in a statement. "As with other missions going to geostationary orbits, the first-stage will be subject to extreme velocities and re-entry heating, making a successful landing challenging."
SpaceX successfully landed a rocket on the drone ship for the first time April 8 after a launch from Cape Canaveral with a Dragon supply ship. That mission went into low Earth orbit on the way to the International Space Station.
The Falcon 9's last launch May 6 ended with another successful landing at sea, with the booster surviving a scorching atmospheric re-entry after launching the JCSAT 14 communications satellite. That was the first Falcon 9 intact recovery on a geostationary mission.
The above photo of the drone ship was taken before a previous launch.

С погодой в районе приземления ступени вроде не очень.

Говорят что в данный момент погода подходящая... но есть риск её ухудшения.
