NASA Announces High School Competition for Future Engineers: Teams to Design Software for Small Satellites on the International Space Station

ISS News

NASA is challenging high school teams to design software to program small satellites aboard the International Space Station. The competition centers on the Synchronized Position Hold, Engage, Reorient, Experimental Satellites, or SPHERES.

SPHERES are bowling ball-sized spherical satellites used to test maneuvers for spacecraft performing autonomous rendezvous and docking. Three of these satellites fly inside the station's cabin. Each is self-contained with power, propulsion, computing and navigation equipment.

The reactivation followed Monday’s spacewalk, the third in a series of excursions that began Aug. 7 to remove and replace an ammonia coolant pump module that failed July 31.

Crew to Perform Second of Three Spacewalks Wednesday

ISS News

Flight controllers and engineers continue meetings to review the results from the first spacewalk conducted Saturday by International Space Station Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson and to plan for the second of what now will be three spacewalks to complete the replacement of a failed pump module on the station's starboard truss.

NASA changes spacewalk strategy for station repair

ISS News

Flight controllers are revising plans for a second spacewalk Wednesday to replace a coolant pump aboard the International Space Station, adding work to isolate an ammonia leak that should clear the way for installation of a new pump during a third spacewalk Sunday.

A formal decision on whether to proceed with the Wednesday spacewalk is expected after NASA's space station Mission Management Team reviews preparations during a meeting Tuesday at the Johnson Space Center in Houston.

Next Spacewalk No Earlier Than Wednesday

ISS News

The next spacewalk to complete the removal of a failed ammonia pump module and installation and activation of a new pump module on the International Space Station's S1 Truss will take place no earlier than Wednesday.

Spacewalks needed to fix station cooling problem

ISS News

Trouble with one of the International Space Station's external coolant loops, used to dissipate the heat generated by the lab's electronics systems, triggered an extensive powerdown late Saturday. NASA managers met Sunday and gave preliminary approval to a difficult two-spacewalk repair job, starting as early as Thursday, to restore the critical system to normal operation.

It is not yet clear what went wrong, but the ammonia pump module that is part of coolant loop A, mounted on the right side of the station's main power truss, failed around 8 p.m. EDT Saturday. A problem somewhere in the system caused a circuit breaker to trip, setting off multiple alarms and waking the crew.

NASA Astronaut Sends First Signed Message from Orbit

ISS News

The number of languages used on the International Space Station has recently increased. In addition to those spoken in the 15 countries that have had representatives aboard the space station, American Sign Language, or ASL, is now included. NASA astronaut Tracy Caldwell Dyson has sent a message in ASL from the station to the deaf community.

In the video, Caldwell Dyson answered several questions about living and working aboard the station and how she became interested in sign language.

"I am truly grateful for this opportunity on behalf of the deaf community and the multitudes of students who will benefit from seeing their language spoken in space," Caldwell Dyson said. "It is my hope that this video will help inspire our next generation of scientists and explorers."

Spacewalk Preparations and Maintenance for Crew

ISS News

The Expedition 24 crew members aboard the International Space Station focused on spacewalk preparations and maintenance activities Wednesday.

To prepare for a six-hour spacewalk set to begin at 11:45 p.m. EDT Monday, Flight Engineers Fyodor Yurchikhin and Mikhail Kornienko installed new batteries in the Russian Orlan spacesuits they will wear on their excursion. The spacewalkers will install Kurs automated rendezvous equipment on the exterior of the recently delivered Rassvet module to facilitate future dockings with Russian spacecraft. A dry run of the spacewalk will take place Friday when the cosmonauts will wear the spacesuits, practice their movements and test their mobility.

Russian resupply ship returns and docks to space station

ISS News

The Russian-American crew living aboard the International Space Station welcomed the safe arrival of a cargo-delivery tug Sunday, two days after the freighter aborted its initial rendezvous and sailed by the orbiting complex.

Flying smoothly on autopilot 350 km above Earth, the Progress M-06M spacecraft linked up to the aft docking port of the station's Zvezda service module at 12:17 p.m. EDT/16:17 GMT.

"Docking the four-corner border of Russia, Kazakhstan, China and Mongolia," NASA commentator Rob Navias announced from Houston's Mission Control Center. "The belated arrival of the Progress 38 cargo ship executed perfectly, flawlessly by the KURS automated rendezvous system."

ISS Progress 38 Docks with Station

ISS News

The ISS Progress 38 cargo resupply ship successfully docked to the aft end of the International Space Station's Zvezda service module at 12:17 p.m. EDT Sunday. The docking was executed flawlessly by Progress' Kurs automated rendezvous system.

The Progress spacecraft carries 1,918 pounds of propellant, 110 pounds of oxygen, 220 pounds of water and 2,667 pounds of experiment equipment, spare parts and other supplies to the station. It launched from the Baikonur Cosmodrome in Kazakhstan on June 30. An attempted docking Friday, July 2, was aborted when telemetry between the Progress and the space station was lost about 25 minutes before its planned docking.
