A robotic Russian cargo vessel blasted off today (Oct. 31), carrying nearly 3 tons of supplies on a Halloween delivery mission to the International Space Station.

The unmanned Progress 49 spacecraft launched from Kazakhstan's Baikonur Cosmodrome at 3:41 a.m. EDT (0741 GMT) today and is slated to arrive at the orbiting lab six hours later. You can watch the rendezvous and docking activities live here on NASA TV, beginning at 9 a.m. EDT (1300 GMT).

Progress 49 is toting 2.9 tons of supplies, including 2,050 pounds (930 kilograms) of propellant, 926 pounds (420 kg) of water, 62 pounds (28 kg) of oxygen and 2,738 pounds (1,242 kg) of spare parts, NASA officials said. There's no word yet on whether any candy corn or miniature chocolate bars made it onboard to help the space station's six astronauts celebrate the season.

Life on orbit is always busy, but this week is particularly jam-packed for station crew.

For example, today's launch comes just three days after SpaceX's unmanned Dragon capsule left the station, wrapping up the first-ever commercial cargo mission to the $100 billion orbiting complex. Dragon splashed down in the Pacific Ocean off the Baja California coast on Sunday afternoon (Oct. 28).

Dragon will make at least 11 more flights to the station under a $1.6 billion contract that California-based SpaceX signed with NASA. Its next launch is currently scheduled for January, agency officials have said.

Dragon is unique in its ability to ferry hardware, supplies and scientific experiments both to and from the space station. All other cargo craft currently operating including Russia's Progress ships carry supplies to the orbiting lab but burn up upon re-entering Earth's atmosphere.

Shortly after welcoming Progress 49 to the station, crewmembers will turn their attention to another task. NASA astronaut Sunita Williams, commander of the orbiting complex's current Expedition 33 mission, and Japanese colleague Akihiko Hoshide will perform a spacewalk Thursday morning (Nov. 1).

Beginning at 8:15 a.m. EDT (1215 GMT) Thursday, Williams and Hoshide will venture to the port side of the station's backbone-like truss to repair an ammonia leak in a radiator. The spacewalk should take about 6 1/2 hours, NASA officials said.

A robotic Russian cargo spacecraft made a Halloween delivery today (Oct. 31) to the International Space Station.

The unmanned Progress 49 spacecraft blasted off from Kazakhstan's Baikonur Cosmodrome at 3:41 a.m. EDT (0741 GMT) today, carrying nearly 3 tons of supplies for the orbiting laboratory. It arrived roughly six hours later, docking at 9:33 a.m. EDT (1333 GMT), as the two vehicles were roughly 250 miles (400 km) above Bogota, Columbia.

Progress 49 is toting 2.9 tons of supplies, including 2,050 pounds (930 kilograms) of propellant, 926 pounds (420 kg) of water, 62 pounds (28 kg) of oxygen and 2,738 pounds (1,242 kg) of spare parts, NASA officials said.

Russian Spacecraft Makes Halloween Cargo Delivery to Space Station

This story was updated at 8:40 a.m. EDT.

Two astronauts are floating outside the International Space Station today (Nov. 1) in an effort to isolate and repair an ammonia leak in part of the orbiting lab's cooling system.

NASA astronaut Sunita Williams and Japanese spaceflyer Akihiko Hoshide officially begun the spacewalk also known as an extra-vehicular activity, or EVA this morning at 8:29 a.m. EDT (1229 GMT). They're expected to stay outside for about 6 1/2 hours, NASA officials said. You can watch live coverage of the spacewalk here on NASA TV.

"Aki, come on in. The water is warm," Williams called to Hoshide as he floated outside the space station's airlock.

Each of the orbiting lab's eight huge solar arrays has its own associated power system, and circulating ammonia helps cool this gear down. The spacewalk's first objective is to find the source of the leak, which could affect one of these power channels if it's not addressed soon.

"We don't know exactly where the leak is," space station manager Mike Suffredini of NASA told reporters during a teleconference last Friday (Oct. 26). "It's possible the leak is in the PVR itself, the [photo-voltaic] radiator itself. It could be in the pump system, or it could be in any one of the [coolant] lines."

On Thursday's EVA, Williams commander of the station's current Expedition 33 mission and Hoshide will make their way over to the port side of the station's backbone-like truss. They'll reconfigure some lines in the affected coolant system and install a spare radiator to see if that stops the leak.

"We're real suspicious of the radiator," said spacewalk flight director Mike Lammers, of NASA's Johnson Space Center in Houston. "It kind of stretches out there and is susceptible to micrometeorite impacts."

Because the leak is so slow, it will likely take several weeks before it's known if the fix works, officials said.

If ammonia continues to escape, the station's operators will eventually have to try something else. For example, they may direct astronauts to swap out some of the coolant system's pump gear on another spacewalk. But there likely won't be an urgent need for a new fix, since the spare radiator should provide enough ammonia to keep the coolant system operating until next October or so, officials said.

Astronauts Begin Spacewalk to Fix Space Station Cooling System

CAPE CANAVERAL, Fla. (AP) An unmanned Dragon freighter carrying a stash of precious medical samples from the International Space Station parachuted into the Pacific Ocean on Sunday, completing the first official shipment under a billion-dollar contract with NASA.

The California-based SpaceX company successfully guided the Dragon down from orbit to a splashdown a few hundred miles off the Baja California coast.

This historic mission signifies the restoration of Americas ability to deliver and return critical space station cargo, Elon Musk, the billionaire founder and head of SpaceX, said in a statement.

NASA Administrator Charles Bolden praised the American ingenuity that made the endeavor possible.

Several hours earlier, astronauts aboard the International Space Station used a giant robot arm to release the commercial cargo ship 255 miles up. SpaceX provided updates of the journey back to Earth via Twitter.

The supply ship brought back nearly 2,000 pounds of science experiments and old station equipment. Perhaps the most eagerly awaited cargo is nearly 500 frozen samples of blood and urine collected by station astronauts over the past year.

The Dragon is the only delivery ship capable of returning items, now that NASAs shuttles are retired to museums. Atlantis made the last shuttle haul to and from the station in July 2011.

SpaceX more formally Space Exploration Technologies Corp. launched the capsule three weeks ago from Cape Canaveral, full of groceries, clothes and other station supplies. Ice cream as well as fresh apples were especially appreciated by the station residents, now back up to a full crew of six.

Its the second Dragon to return from the orbiting lab; the first mission in May was a flight demo. This flight is the first of 12 deliveries under a $1.6 billion contract with NASA.

It was nice while she was on board, space station commander Sunita Williams said as the Dragon backed away. We tamed her, took her home and, literally and figuratively, theres a piece of us on that spacecraft going home to Earth.

Two spacewalking astronauts troubleshot an ammonia leak in the International Space Station's cooling system today (Nov. 1), accomplishing the chief objective of their marathon excursion outside the orbiting lab.

NASA astronaut Sunita Williams and Japanese spaceflyer Akihiko Hoshide ventured outside the space station at 8:29 a.m. EDT (1229 GMT) today. A little more than five hours later, they had reconfigured some coolant lines and deployed a spare radiator, isolating the leak.

"Suni and Aki, heartfelt congratulations to you," NASA astronaut Mike Fincke, who helped walk the astronauts through their tasks from mission control at the agency's Johnson Space Center in Houston, said at 1:41 p.m. EDT (1741 GMT). "We accomplished just about everything we set out to do today."

"A big, huge congratulations to you guys on the ground for putting this together," Williams responded. [Gallery: Building the International Space Station]

Today's spacewalk was slated to last about 6 1/2 hours, and it proceeded pretty much on schedule. By 2:58 p.m. EDT (1958 GMT), both astronauts had re-entered the space station through its airlock, and the spacewalk was officially over nine minutes later.

Finding the leak

Each of the space station's eight huge solar panels has its own associated power system, and circulating ammonia helps cool this gear down. The leak, which NASA and its space station partners first noticed in 2007, has the potential to affect one of these power channels if it's not fixed.

Today's spacewalk, or extra-vehicular activity (EVA), is a crucial step in that process.

At the start of the spacewalk, Williams commander of the station's current Expedition 33 and Hoshide made their way over to the port side of the station's backbone-like truss. They rejiggered some lines in the affected coolant system and installed a spare radiator.

NASA officials hope this stops the leak, which they suspect may be coming from the old (swapped-out) radiator.

Spacewalking Astronauts Isolate Leak in Space Station Cooling System

CAPE CANAVERAL, Florida (Reuters) - A pair of spacewalking astronauts floated outside the International Space Station on Thursday to bypass a leak in one of the outpost's cooling systems.

Engineers suspect a micrometeoroid or tiny piece of space debris may have punched a hole no bigger than the width of a hair into one of the station's radiators.

The devices dissipate heat from batteries and other equipment aboard the solar-powered station, a $100 billion laboratory for biological, fluid physics and other science experiments now flying about 255 miles above Earth.

Station commander Sunita Williams and flight engineer Akihiko Hoshide left the station's Quest airlock around 8:30 a.m. EDT (1230 GMT) and returned 6.5 hours later after reconfiguring some ammonia coolant lines and hooking up a spare radiator.

"Suni and Aki, our heartfelt congratulations to you and the entire team," astronaut Mike Fincke radioed to the spacewalkers from Mission Control in Houston. "We've accomplished just about everything we set out to do today."

The leak is small so it will take several weeks to determine if the radiator was the source, said space station program manager Mike Suffredini.

If routing ammonia through the spare radiator does not stem the leak, another spacewalk to replace a pump or other equipment in the system may be needed.

Unless it is fixed, the leak would eventually trigger the cooling system to shut down, leaving the station without a backup system for a section of the station's solar arrays.

The cooling system holds about 50 pounds (22.7 kg) of ammonia. It would automatically shut down if the ammonia level drops to 40 pounds (18 kg), said flight director Mike Lammers.

As ground control teams prepared for the spacewalk on Wednesday, the station had to maneuver to avoid another piece of debris, part of the wreckage from the 2009 collision of an Iridium communications satellite and a Russian satellite.

Spacewalkers tackle coolant leak on space station

ScienceDaily (Oct. 16, 2012) With all the prepackaged gardening kits on the market, an exceptionally green thumb isn't necessary to grow your own tasty fresh vegetables here on Earth. The same may hold true for U.S. astronauts living and working aboard the International Space Station when they receive a newly developed Vegetable Production System, called VEGGIE for short, set to launch aboard SpaceX's Dragon capsule on NASA's third Commercial Resupply Services mission next year.

"Our hope is that even though VEGGIE is not a highly complex plant growth apparatus, it will allow the crew to rapidly grow vegetables using a fairly simple nutrient and water delivery approach," said Howard Levine, Ph.D. and chief scientist, NASA's Kennedy Space Center International Space Station Research Office.

Gioia Massa, a postdoctoral fellow in the Surface Systems Group of Kennedy's Engineering Directorate, has been working with the International Space Station Research Office to validate the VEGGIE hardware here on Earth before it takes flight next year.

"VEGGIE could be used to produce faster-growing species of plants, such as lettuce or radishes, bok choy or Chinese cabbage, or even bitter leafy greens" Massa said. "Crops like tomatoes, peas or beans in which you'd have to have a flower and set fruit would take a little longer than a 28-day cycle."

It may not sound like a big deal to us Earthlings who can just run out to our local produce stand or supermarket when we have a hankering for a salad, but when you're living 200 miles above the surface of the planet, truly fresh food only comes a few times a year.

"When the resupply ships get up there, the fresh produce gets eaten almost immediately," Massa said.

Weighing in at about 15 pounds and taking up the space of a stove-top microwave oven, the stowable and deployable VEGGIE system was built by Orbital Technologies Corporation, or ORBITEC, in Madison, Wis. The company designed the system to enable low-maintenance experiments, giving astronauts the opportunity to garden recreationally.

"Based upon anecdotal evidence, crews report that having plants around was very comforting and helped them feel less out of touch with Earth," Massa said. "You could also think of plants as pets. The crew just likes to nurture them."

In simple terms, the VEGGIE system works like this: Clear Teflon bellows that can be adjusted for plants as they grow are attached to a metal frame housing the system's power and light switches. A rooting pillow made of Teflon-coated Kevlar and Nomex will contain the planting media, such as soil or claylike particles, along with fertilizer pellets. Seeds either will be preloaded in the pillows on Earth or inserted by astronauts in space. To water the plants, crew members will use a reservoir located beneath the pillows and a root mat to effectively add moisture through an automatic wicking process.

VEGGIE is set to join other plant growth facilities that vary in size and complexity, such as the Lada greenhouse unit and the ABRS, short for Advanced Biological Research System. VEGGIE is the simplest of the three designs, but has the largest surface area for planting and is expected to produce data on a more regular basis. Levine noted that the ability to grow plants in microgravity has really evolved throughout the past decade.

Tiny Satellites Launch From Space Station (Photos)

Astronauts on the International Space Station have transformed their high-flying laboratory into a new kind of launch pad for tiny satellites in a bid to boost student interest and access to space.

This month, the space station's Expedition 33 crew launched five tiny Cubesats, each only a few inches wide, using a small satellite orbital deployer from Japan's space agency JAXA. They were the first Cubesat satellites ever launched from the International Space Station, coming 2 1/2 years after NASA announced the CubeSat program.

"This was a learning experience for everyone," said Andres Martinez, the NASA Ames project manager for one of the satellites.

The cubesats were launched from the station's Japanese Kibo laboratory on Oct. 4, which also marked the 55th anniversary of the world's first satellite launch in 1957 that placed Russia's Sputnik 1 in orbit and ushered in the Space Age. [Photos: Tiny Satellites Launch from Space Station]

"Fifty-five years ago we launched the first satellite from Earth. Today we launched them from a spacecraft," space station commander Sunita Williams of NASA said on launch day to mark the moment. "Fifty years from now, I wonder where we'll be launching them from."

The JAXA satellite-deploying device arrived at the station aboard a Japanese cargo ship in July. Japanese astronaut Akihiko Hoshide placed the deployer, which is about the size of a small rabbit cage, into a small airlock in the Kibo lab. Then, the astronaut sealed the airlock, opened it up to space, and commanded the station's Kibo robotic armto pick up the deployer and bring it outside for satellite deployment.

All told, the procedure took only four hours of astronaut time with no spacewalk required.

"If you can imagine, deploying satellites from station can be quite risky," Martinez said. "We were going through that whole experience of conducting analysis to ensure this would be something safe to do from station, not only from the point of deployment but also taking up the satellites inside station."

The International Space Station appears to go to warp speed a la Star Trek, Star Wars and almost every other space flick in this new video created by Christoph Malin, who stacked image sequences that the ISS crew at International Space Station have been taking lately. These are the images that have been used to create the great timelapse videos, that provide a sense of what it is like to fly over the Earth on the space station. But this one is different, and as Malin says, Stacks make interesting patterns visible, for example lightning corridors within clouds. One can also sometimes recognize satellite tracks and meteors patterns that are not amongst the main star trails.

Also visible is the Moon disappearing into the atmosphere and views from the ISS Cupola gorgeous!
