At mission control in California. Launch in 60 mins. Looks good so far.

сколько времени необходимо барже, чтобы выйти из порта и достигнуть точки стояния?

[Nilk]

А ведь должны были запустить ещё 12 сентября - 4 месяца задержка. Если бы снабжение МКС осуществлялось бы с помощью только Драконов да Цигнусов, космонавты похли бы уже с голода

0850 GMT (3:50 a.m. EST)
 The launch weather officer reports all weather rules are currently "green" and expected to remain so for the rest of the countdown.
Launch time conditions are predicted to be partly cloudy skies with scattered clouds at 5,000 feet, 16,000 feet and 23,000 feet. Winds will be fr om the northwest at 10 to 15 mph, and temperature will be about 50 degrees Fahrenheit.
The only minor concern is a 10 percent chance of a violation of the thick cloud rule.
          
0847 GMT (3:47 a.m. EST)
 T-minus 60 minutes and counting. All four propellant tanks on the Falcon 9 rocket are now in topping mode. The cryogenic liquid oxygen tanks on the first and second stages will continue to be slowly replenished until the final minutes before launch to replace propellant that gradually boils off due to the warm ambient temperatures in Florida.
          
0830 GMT (3:30 a.m. EST)
 NASA TV coverage of the Falcon 9 launch is beginning now.
          
0820 GMT (3:20 a.m. EST)
 Testing has been completed on the Falcon 9 rocket's flight termination system, which would be used to destroy the rocket if a problem occurred in flight.
          
0805 GMT (3:05 a.m. EST)
 The Dragon spacecraft is packed with more than 2.5 tons of scientific experiments, provisions and maintenance items.
Among the supplies packed inside are spacewalk tools and equipment to help prepare the space station to receive commercial crew vehicles, an IMAX camera for filming during four space station increments, and science payloads that will enable model organism research using fruit flies and will study flatworms to better understand wound healing in space.
The Dragon's total internal payload includes 1,272 pounds of science and research gear, 1,080 pounds of crew provisions, 1,495 pounds of vehicle hardware, 35 pounds of computer tools, 51 pounds of spacesuit equipment, and 86 pounds of Russian hardware.
NASA's Cloud-Aerosol Transport System is bolted inside Dragon's unpressurized trunk. The space station's robotics system will unpack the CATS instrument and mount it outside the station to monitor cloud and aerosol coverage which directly impacts global climate.
Today's launch marks SpaceX's fifth operational resupply run to the space station under a 12-mission, $1.6 billion contract with NASA covering cargo services through 2016.
 
0715 GMT (2:15 a.m. EST)
 Fueling of the Falcon 9 rocket is underway at Cape Canaveral's Complex 40 launch pad.

0650 GMT (1:50 a.m. EST)
 Fueling of the 208-foot-tall Falcon 9 rocket is about to get underway at Cape Canaveral's Complex 40 launch pad.
The two-stage rocket burns RP-1 fuel -- a high-refined kerosene -- and liquid oxygen during today's nine-minute launch sequence.
Today's flight marks the 14th launch of a Falcon 9 rocket since debuting in June 2010. It's the 9th mission of the improved Falcon 9 v1.1 version, which made its inaugural launch in September 2013 from Vandenberg Air Force Base.
For details on the Falcon 9 v1.1, here is part of our story on the rocket stemming from an interview with SpaceX boss Elon Musk in 2013:
Musk said the redesigned Falcon 9 is the prototype for a reusable rocket SpaceX envisions could drastically reduce launch costs, decreasing the price of a Falcon 9 flight even lower than SpaceX's advertised rate, which undercuts competing rockets, such as the Russian Proton and Europe's Ariane 5 launcher.
It is this version of the Falcon 9 that SpaceX hopes will safely deliver astronauts to orbit on the way to the space station, beginning as soon as 2017.
Reliability is paramount in the launch business, and cost and schedule are right behind in a matrix of concerns for rocket buyers.
Musk said SpaceX answered these appeals, and added power and efficiency to the Falcon 9's Merlin engines to loft heftier payloads into higher orbits.
SpaceX engineers installed a triple-redundant flight computer in the Falcon 9 rocket, adding another level of confidence in the launcher's avionics. They also wrote new software for the computer, which is based on a flight-proven unit from SpaceX's Dragon cargo-carrying space station freighter.
"You could put a bullet hole in any one of the avionics boxes and it would just keep flying," Musk said.
Designers adjusted the connection points between the Falcon 9's first and second stages, replacing nine hardware interfaces and three spring-like pusher elements - pneumatic devices which ensure stage separation occurs - with three connectors with integrated pushers.
"We go from 12 things that can go wrong to three at the point of staging," Musk said.
The Falcon 9 v1.1 is powered by 10 Merlin 1D engines - nine on the first stage and one on the second stage - each generating 147,000 pounds of sea level thrust. The vacuum-rated upper stage engine, sporting a niobium nozzle to radiate engine heat, produces 161,000 pounds of thrust once out of the atmosphere.
The Merlin 1C engine, used on all five of the Falcon 9's previous missions, was capable of firing with 95,000 pounds of thrust at sea level.
Along with greater performance, the Merlin 1D is easier to manufacture thanks to high-efficiency processes, increased robotic construction and a reduced parts count, according to SpaceX's press kit.
SpaceX upgraded the propellant injection system inside the Merlin 1D, replacing two valves dedicated to fuel and oxidizer with a single unit to improve reliability and save weight.
Musk said the Merlin 1D engine weighs in at less than 1,000 pounds.
"If we don't have the world record for thrust-to-weight ratio, we're very close," Musk said.
Musk's rocket team modified the engine arrangement on the first stage, an effort he said allows engineers to remove aerodynamic manifolds around the perimeter of the rocket.
Earlier Falcon 9s featured a square "tic-tac-toe" layout of the nine first stage engines arrayed in a three-by-three pattern. The Falcon 9 v1.1 uses what SpaceX calls an "octaweb" design, with eight engines surrounding a center engine in a circular pattern.
According to Musk, engineers installed ablative bumpers between the engines to prevent a mishap with one engine from damaging another.
The first stage upgrades also include a heat shield and stretched propellant tanks for the Merlin engines' supply of kerosene and liquid oxygen.
"We put a stronger heat shield at the base of the rocket to better enable the first stage to survive the high dynamic pressure on re-entry," Musk said.
The new Falcon 9 first stage is 60 percent longer but has the same diameter as the Falcon 9's previous version, permitting the rocket to be fabricated with the same tooling already inside SpaceX's rocket factory in Hawthorne, Calif.
