SpaceX's robotic Dragon capsule is slated to blast off Sunday night (Oct. 7) on the first-ever bona fide private cargo run to the International Space Station.

In May, Dragon become the first commercial spacecraft to visit the station. But that was a demonstration flight, while Sunday's launch kicks off the first of 12 unmanned supply missions SpaceX will make for NASA under a $1.6 billion contract.

Dragon will deliver about 1,000 pounds (454 kilograms) of supplies, then return to Earth on Oct. 28 carrying more than 1,200 pounds (544 kg) of different gear down from the space station. Here's how the mission will work.

Getting into space

The Dragon capsule is set to blast off atop SpaceX's Falcon 9 rocket at 8:35 p.m. EDT Sunday (0035 GMT Monday). The mission has an instantaneous launch window, so if anything causes a delay Sunday, liftoff will be pushed to another day.

At about 1 p.m. EDT Sunday (1700 GMT), Dragon and the Falcon 9 will be powered up, and fueling of the rocket will begin three and a half hours later. [SpaceX's Dragon Poised to Launch Sunday (Photos)]

The terminal countdown begins at T-minus 10 minutes and 30 seconds, at which point all launch systems will be autonomous. A final "go" for launch will come at T-minus 2 minutes and 30 seconds, NASA officials said.

Seventy seconds after liftoff, the Falcon 9 rocket will reach supersonic speed. By 2.5 minutes into the flight, it will be traveling 10 times the speed of sound, at an altitude of 56 miles (90 kilometers). At about this time, the rocket's main engines will cut off.

A few seconds later, the Falcon 9 rocket's first and second stages will separate, with the second stage soon performing a six-minute burn to take Dragon to low-Earth orbit.

Nine minutes and 49 seconds after launch, Dragon will separate from the rocket's second stage. Seconds later, the capsule will reach its preliminary orbit, at which point it will deploy its solar arrays and begin a series of thruster firings to get it close to the space station.

How SpaceX's First Space Station Cargo Mission Will Work

A private company is on the verge of launching another cargo ship to the International Space Station.

California-based SpaceX will attempt to send a Dragon capsule to the orbiting lab on Sunday night. Liftoff is scheduled for 8.35pm EDT (1235 AEDT Monday).

Forecasters put the odds of acceptable weather at 60 per cent. Thick clouds and rain are the main concerns.

A Dragon cargo ship successfully docked to the space station last May, but that was considered a test flight.

The coming mission is the first under a $1.6 billion contract with NASA that calls for a dozen resupply flights by SpaceX, essential in the post-shuttle era.

The Dragon will remain docked to the space station for most of October. Astronauts will fill the capsule with blood and urine samples, other experiments and old equipment, for its return to Earth.

The nearly 500 tubes of blood and syringes of urine have been stashed in space station freezers since the last space shuttle flight, by Atlantis, in July 2011.

The decommissioned Atlantis, and sister ships Discovery and Endeavour, are now museum relics.

NASA nutritionist Scott Smith said the blood and urine samples - part of medical studies - will be the first to be returned since Atlantis' final voyage more than a year ago.

"This is the first real return vehicle for this type of sample," Scott told reporters on Saturday.

Private space station delivery to launch

A private Dragon space capsule is poised for a weekend launch to the International Space Station with the first big cargo shipment ever aboard an unmanned American spacecraft.

The gumdrop-shaped Dragon spacecraft, built by the commercial spaceflight company SpaceX, will blast off on Sunday (Oct. 7) from a launch pad at Cape Canaveral Air Force Station in Florida. Liftoff is set for 8:35 p.m. EDT (0035 Monday GMT), with a planned arrival at the station set for on Wednesday (Oct. 10).

SpaceX and NASA mission managers met Friday to review the preparations for the Dragon flight atop its Falcon 9 rocket, ultimately giving the mission a final "go" for launch. There is a 60 percent chance of good weather for launch.

"It's going to be a very exciting night on Sunday," SpaceX founder Elon Musk said during a Google+ hangout event with NASA chief Charles Bolden today ahead of the review. "I always get kind of nervous before these flights, thinking, like 'What have we missed?'" [SpaceX's Dragon Poised to Sunday Launch (Photos)]

Musk said he and his SpaceX team have done their best to ensure a successful launch Sunday, and while there is always the chance of something going wrong, "I feel like we've done everything we can to make the mission as successful as possible, and I hope people enjoy watching it."

Private delivery for space station

The Dragon mission, the first official cargo run by a private American-built spacecraft, is a watershed flight for NASA and SpaceX. The Hawthorne, Calif.-based company has a $1.6 billion deal with NASA for at least 12 resupply missions to the space station using its robotic Dragon capsules and their Falcon 9 rocket boosters.

The deal is part of NASA's Commercial Resupply Services (CRS) program. With the retirement of NASA's space shuttle fleet last year, the space agency is depending on the availability of new private space taxis to provide unmanned cargo deliveries to the station, as well as ferry American astronauts to and from low-Earth orbit.

Another U.S. company, the Virginia-based Orbital Sciences Corp., has a $1.9 billion agreement to fly at least eight resupply missions to the station using its own Antares rockets and Cygnus spacecraft, and plans to launch a rocket test flight later this year. But SpaceX is the first of the two firms to actually launch vehicles to the International Space Station.

In May, SpaceX (short for Space Exploration Technologies) launched a different Dragon capsule and Falcon 9 rocket on a test flight to the station. That mission demonstrated SpaceX's ability to launch Dragon to the station, have it rendezvous with the orbiting lab safely, and then be captured for docking using a robotic arm controlled by astronauts inside the outpost.

Private Dragon Spacecraft 'Go' to Launch Space Station Cargo Sunday

Ice cream is blasting off for the crew of the International Space Station (ISS).

The frozen confectionery not the freeze-dried souvenir version sold in museum gift shops is packed on board the first NASA-contracted commercial mission to resupply the orbiting laboratory.

The Commercial Resupply Services-1 (CRS-1) mission is scheduled to lift off on a Space Exploration Technologies (SpaceX) Falcon 9 rocket on Sunday (Oct. 7) at 8:35 p.m. EDT (0035 GMT Oct. 8) from Launch Complex 40 at the Cape Canaveral Air Force Station in Florida.

The ice cream, which is now a not-so-secret surprise for the station's current three member crew, was confirmed as on board SpaceX's Dragon cargo capsule by NASA after a pre-launch press conference Saturday (Oct. 6) raised the possibility that it was included.

"We talked about flying ice cream," said NASA's manager for the space station program, Michael Suffredini. "We try to bring up what we call 'bonus food' for the crew, and this is one of those flights that will have that." [Space Food Photos: What Astronauts Eat in Orbit]

GLACIER goodies

The vanilla with swirled chocolate sauce ice cream cups won't melt on their three-day journey to the space station thanks to a freezer on board the Dragon capsule.

"We're very excited," SpaceX president Gwynne Shotwell told reporters. "This is the first time we are taking powered cargo up. We are taking up a GLACIER freezer, which has refrigerated science samples in it."

The GLACIER, or General Laboratory Active Cryogenic ISS Experiment Refrigerator, is primarily used to preserve science samples that require temperatures between minus 301 and 39 degrees Fahrenheit (minus 160 and 4 degrees Celsius) on the way to or from the space station. The mini-fridge sized freezer previously flew aboard the space shuttle.

"Having been on a flight that had an empty freezer on it going up into space, we did fill it [with ice cream] and it's really nice!" Robert Cabana, former shuttle astronaut and the director of NASA's Kennedy Space Center, said.

Astronaut Ice Cream: Frozen Dessert Launching to Space Station

A piece of space junk that may buzz the International Space Station Monday has NASA weighing plans to move the orbiting lab, even as a private space capsule stands poised to launch toward the station on Sunday night.

The space debris will pass near enough to the space station on Monday morning (Oct. 8) to require an avoidance maneuver as a safety precaution, NASA space station program manager Mike Suffredini said in a briefing today (Oct. 6).

The decision on whether to move the station is not yet final, but if such a maneuver is required it will not affect the scheduled launch of a private Dragon space capsule to the station, Suffredini said.

Built by the private spaceflight company SpaceX, the unmanned Dragon spacecraft is set to launch Sunday night at 8:35 p.m. EDT (0035 Monday GMT) from a pad at Cape Canaveral Air Force Station in Florida. The spacecraft is packed with about 1,000 pounds (453 kilograms) of supplies for the space station's three-person crew, including food and science gear.

"I can't imagine a scenario in which we ask SpaceX not to launch," Suffredini said.

Suffredini said that if the space station does have to dodge the debris, it would likely just mean SpaceX's Dragon will take a bit longer to arrive than planned. Currently, the spacecraft is due to dock at the station on Wednesday (Oct. 10). [SpaceX's Dragon Poised to Sunday Launch (Photos)]

"They'll just adjust while they're flying if we have to do the move," Suffredini said.

NASA and its space station partners regularly move the space station when a piece of debris is expected to pass inside a preset safety perimeter. That safety zone is shaped like a pizza box and extends out 15 miles (25 kilometers) to either side, as well as a half-mile (0.75 km) above and below the station.

SpaceX's Dragon flight to the space station is the first commercial cargo delivery to the outpost under a $1.6 billion deal with NASA. That agreement calls for SpaceX to provide at least 12 cargo missions to the station using its robotic Dragon space capsules and Falcon 9 rockets.

The Hawthorne, Calif.-based SpaceX flew a successful demonstration flight to the station in May that set the stage for Sunday night's launch. Another company, Orbital Sciences Corp. of Virginia, is developing its own private rocket and spacecraft to fly cargo to the station under a $1.9 billion deal with NASA.
