In a spacewalk, Astronauts Chris Cassidy and Tom Marshburn replaced a pump component that has been gushing ammonia coolant, NASA reported Saturday. The spacewalk got underway at 5:44 a.m. PDT and was expected to last more than six hours, according to NASA. The astronauts removed and replaced the faulty pump controller box on the far port truss of the International Space Station. No evidence of a continued ammonia leak was evident as NASA restarted the faulty coolant loop. Live footage on NASA TV showed the two working in painstakingly slow motion in alternating darkness and light as the station circled Earth.

While orbiting Earth at about 17,000 mph, SpaceX's Dragon capsule Thursday came within 1.5 miles of the International Space Station in preparation for its historic hookup scheduled for later this week. The fly-by, confirmed by NASA in its webcast , is a crucial step for the company, officially known as Space Exploration Technologies Corp., and its goal of becoming the world's first private firm to dock a craft with the space station. The Dragon's onboard sensors and flight systems are now undergoing a series of tests to determine whether the vehicle is ready to berth with the space station.

Anyone who thinks the U.S. space program is done with and permanently parked at the California Science Center in the form of the space shuttle Endeavour hasn't heard NASA astronaut Tracy Caldwell Dyson and aerospace engineer Camille Alleyne (yes, a rocket scientist) talk about the International Space Station. Which is what they were doing on a very earthbound mission this week in Los Angeles to promote NASA's involvement in the space station and the exhibit, “Destination: Station,” showcasing what it's like to live aboard the International Space Station.

A 330-pound humanoid robot has been electronically awakened aboard the International Space Station, beginning its life as an astronaut's assistant. The robot named Robonaut 2, or R2, will help with routine tasks such as holding tools and vacuuming air filters. The robot was sent up on the space shuttle Discovery in February, but it wasn't powered up until this week. Clad in a gold helmet with a shiny metallic visor, R2 has a torso, two arms and two five-fingered hands. For now, it sits on a fixed pedestal inside the space station.

A cooling system failure aboard the International Space Station may require a spacewalk, NASA officials said Wednesday. One of two ammonia cooling loops on the station's exterior shut down Wednesday morning, NASA spokeswoman Brandi Dean said. “You need the cooling in space because heat doesn't dissipate like it does on the ground,” she said. Authorities think that an excess of ammonia triggered a safeguard to shut the loop down. [Update, 9:05 p.m. Dec. 11: NASA's Johnson Space Center used Twitter to update followers on the situation.

WASHINGTON - After more than 12 years and at least $100 billion in construction costs, NASA leaders say the International Space Station finally is ready to bloom into the robust orbiting laboratory that the agency envisioned more than two decades ago. "The ISS has now entered its intensive research phase," said Bill Gerstenmaier, head of NASA operations and human exploration, in recent testimony to Congress in defense of the roughly $1.5 billion...

While its scientific merits remain debatable and its cost busted budgets years ago, the international space station has proven successful in at least one important mission: as a vehicle for diplomacy. Today, at about 3:40 p.m. PDT, U.S. astronauts Ken Bowersox and Don Pettit and Russian cosmonaut Nikolai Budarin will leave the orbiting station aboard a Russian Soyuz capsule filling in for the grounded U.S. shuttle fleet.

When the $30-billion international space station is completed, it will rank as the most costly single object ever created--surpassing the price tag on any machine, aircraft, computer, weapon, power plant or edifice. It will orbit Earth as a dramatic symbol of human intent to explore the furthest reaches of space, its proponents say. And it will epitomize a new international collaboration between North America, Europe and Asia to jointly conduct big-ticket scientific research.

Spacewalking astronauts secured a "front porch" Saturday to the International Space Station that will expose scientific experiments to the cold vacuum of outer space. Lead spacewalker David Wolf and rookie astronaut Timothy Kopra spent about 5 1/2 hours outside the station preparing the Japanese-built platform to be attached to the front of the station's $2.4-billion Kibo laboratory. Then, using a robotic arm, astronauts gingerly drove the 4-ton platform to "hard dock" with the Kibo lab.
