There is now just a 30 percent chance weather conditions will permit liftoff of a Falcon 9 rocket tonight.

The main concerns are with thick clouds and precipitation over Cape Canaveral as a weather system traverses Central Florida. Two weather rules -- the thick cloud and disturbed weather rules -- are currently "no go" at the launch site.

Liftoff time has been adjusted by one second to 2:14:38 a.m. EDT (0614:38 GMT) based on the latest orbit data for the International Space Station.

0320 GMT (11:20 p.m. EDT on Fri.)
Fueling of the 208-foot-tall Falcon 9 rocket is about to get underway at Cape Canaveral's Complex 40 launch pad after the SpaceX launch team issued a "go" to begin propellant loading.

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 13th launch of a Falcon 9 rocket since debuting in June 2010. It's the 8th 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 last year:

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.

0245 GMT (10:45 p.m. EDT on Fri.)
Rainfall is starting to taper off here at Cape Canaveral, but two weather rules are still observed "no go" at this time. Those are the disturbed weather and thick cloud rules.

0025 GMT (8:25 p.m. EDT on Fri.)
Persistent rain showers over Cape Canaveral may clear in time for liftoff at 2:14 a.m. EDT (0614 GMT), but weather conditions at the Falcon 9 launch site are currently observed "no go" for launch at this time.

Seven weather criteria -- the surface electric field mill rule, the lightning rule, the cumulus cloud rule, the attached anvil cloud rule, the disturbed weather rule, the thick cloud rule and the flight through precipitation rule -- are currently in a "red" status.

 The Falcon 9 and Dragon were powered up Friday evening for countdown activities, with computer and systems testing being completed before the start of fueling.

0502 GMT (1:02 a.m. EDT)
 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.

SCRUB. SpaceX has called off this morning's launch attempt due to bad weather.

0540 GMT (1:40 a.m. EDT)
The Dragon spacecraft is packed with more than 2.5 tons of scientific experiments, provisions and maintenance items.

Among the supplies packed inside are the first 3D printer to be launched into space, 20 mice riding in a specially-made habitat, an instrument to monitor ocean winds, and a commercial experiment that could improve the design of golf clubs.

The Dragon's total internal payload includes 1,644 pounds of science and research gear, 1,380 pounds of crew provisions, 403 pounds of vehicle hardware, 101 pounds of computer tools and 55 pounds of spacesuit equipment.

A $26 million NASA instrument is mounted inside the Dragon capsule's external trunk section. Named RapidScat, the instrument will be placed outside the space station to measure ocean winds and aid in hurricane forecasting.

Today's launch marks SpaceX's fourth operational resupply run to the space station under a 12-mission, $1.6 billion contract with NASA covering cargo services through 2016.

Persistent rain showers and clouds at SpaceX's Cape Canaveral launch base kept a Falcon 9 rocket grounded Saturday, delaying the start of a resupply mission to the International Space Station by at least one day.

Despite a grim forecast, SpaceX ground crews readied the 208-foot-tall booster for a middle-of-the-night launch Saturday, pumping kerosene and liquid oxygen propellants into the Falcon 9 rocket as the countdown moved toward liftoff at 2:14 a.m. EDT (0614 GMT).

But Mother Nature had other plans as steady rainfall loomed over Florida's Space Coast accompanied by thick clouds that violated launch weather criteria.

SpaceX called off the launch with approximately 30 minutes left to go in the countdown and began procedures to drain the rocket's propellant tanks and configure systems for another try Sunday at 1:52 a.m. EDT (0552 GMT).

Meteorologists expected weather conditions to improve later Saturday, but the forecast for Sunday's early morning launch opportunity still called for iffy weather with a 60 percent chance thick clouds and precipitation could prevent liftoff.

If weather or technical problems keep the Falcon 9 from launching Sunday, the next attempt would occur Tuesday.

The rocket is crowned with a SpaceX-built Dragon cargo capsule packed with more than 5,100 pounds of experiments and supplies for the International Space Station.

The flight marks SpaceX's fourth operational resupply run to the space station under a 12-mission, $1.6 billion contract with NASA.

The cargo includes a habitat with 20 mice to probe how microgravity causes muscle atrophy, a 3D printer to demonstrate in-space component manufacturing, and a $26 million NASA instrument to measure winds over the world's oceans.

The Dragon supply ship will reach the space station Tuesday if it can launch Sunday, with its pursuit culminating with a laser-guided final approach before the free-flying craft is grappled by the outpost's Canadian-built robotic arm.

After a one-month mission, the automated spaceship will depart the station and return to Earth to a splashdown in the Pacific Ocean with research samples and other gear.
