Space Station’s new cooling system powered up, "fully functional"

Posted on by

Coolant loop A, one of two used to dissipate the heat generated by the space station's electronic systems, was partially shut down Dec. 11 when a flow control valve in an ammonia pump module malfunctioned, resulting in lower-than-allowable temperatures. Non-essential systems in the station's forward modules had to be shut down, including many of the lab's major research facilities.

During an earlier spacewalkSaturday, astronauts Rick Mastracchio and Mike Hopkins disconnected and removed the suspect pump module from its rack on the right side of the station's power truss. In a second spacewalkTuesday, the astronauts successfully installed a spare pump module and reconnected ammonia coolant lines and electrical cables.

Flight controllers performed a brief "aliveness" test before the second spacewalk was over. Then, starting around4:30 p.m. EST(GMT-5), commands were uplinked to start pressurizing the new pump.

"Reactivation of the pump now is complete, and it is performing its job regulating the flow and temperature of the ammonia in loop A of the two-loop cooling system," NASA said in a statement.

Equipment normally cooled by loop A and powered down in the wake of the pump module valve problem will be reactivated over the next several days, the statement said. Other components that were temporarily switched over to coolant loop B will be returned to loop A in a carefully orchestrated sequence.

Tuesday's spacewalk was the 258th by U.S. astronauts, the 176th devoted to station assembly and maintenance since construction began in 1998, the 10th so far this year, the eighth for Mastracchio and the second for Hopkins.

Mastracchio's total through eight spacewalks now stands at 51 hours and 28 minutes, moving him up to sixth on the list of most experienced spacewalkers. Hopkins total EVA time through two spacewalks stands at 12 hours and 58 minutes.

One hundred and 14 astronauts and cosmonauts have now spent 1,107 hours and 37 minutes of spacewalk time building and maintaining the International Space Station since construction began in 1998.

The International Space Station can be seen cruising in front of a crescent moon in this stunning night sky photo recently sent to SPACE.com.

Juan Gonzalez-Alicea of Sociedad de Astronomia del Caribe captured the image from western Puerto Rico on Dec. 6 using a Canon 7D with a 300 mm lens. "I was able to capture the ISS [International Space Station]passing in front of the moon, Gonzalez-Alicea wrote SPACE.com. "It was an amazing sight since Venus was at maximum brightness below the crescent moon.

Venus was at its greatest brilliance on the evening of Friday, Dec. 6, but the planet will be at its maximum brightness all month. It remains highest in the sky the first half of December, descending back down toward the horizon the second half of the month. [Spectacular Night Sky Photos by Stargazers: December 2013 (Gallery)]

The moon is 222,800 miles (358,700 km) away from Earth while Venus is currently approximately 38.5 million miles (61.9 million kilometers) away.
