ISS hit by power outage NASA NEWS RELEASE Posted: February 12, 2007 HOUSTON - An unexpected circuit breaker trip early Sunday caused a power outage on the International Space Station. All systems were back up by Monday morning with no impact to operations on board. The safety of the Expedition 14 crew and the complex was never an issue. The first indications of a problem came with the loss of communications between the station and mission control just after 12:00 a.m. CST Sunday when an electrical switching unit experienced a brief malfunction that appropriately caused a breaker to trip, protecting the electrical system of the station much like a circuit breaker protects electrical systems and equipment in a home. Expedition 14 Commander Mike Lopez-Alegria and Flight Engineers Mikhail Tyurin and Suni Williams - awake since mid-evening Saturday - took immediate action and followed procedures on board to recover the communications link with mission control, Houston, at about 1:35 a.m. During the remainder of Sunday and through early Monday, restoration of systems continued. The systems affected included:
None of these systems was permanently affected, and the equipment's temporary shut down did not impact research work or upcoming planned activities. In addition to the recovery from the power outage, the crew also began early preparations for the next spacewalk by Tyurin and Lopez-Alegria. During that spacewalk scheduled for Feb. 22, the two will free a stuck antenna on the ISS Progress 23 supply craft and survey navigation systems for the European Automated Transfer Vehicle's docking capability to the Zvezda Service Module. They will try to secure or remove the antenna to preclude any interference during undocking in April. The spacewalk will be the 10th for Lopez-Alegria, which will be a U.S. astronaut record. The two will wear Russian Orlan suits for the excursion out of the Pirs docking compartment. |

Space shuttle Atlantis emerges from its processing hangar at dawn February 7 for the short trip to the Vehicle Assembly Building at Kennedy Space Center's Complex 39.
Shuttle Columbia carried the first United States Microgravity Laboratory during its summer 1992 flight to orbit. The Spacelab science expedition was the longest shuttle mission to date, thanks to the new Extended Duration Orbiter equipment flown for the first time. The crew of STS-50 narrate the highlights in this post-flight film.
The documentary "Research Project: X-15" looks at the rocketplane program that flew to the edge of space in the effort to learn about the human ability to fly at great speeds and aircraft design to sustain such flights.
On the 40th anniversary of the Apollo 1 fire that took the lives of astronauts Gus Grissom, Ed White and Roger Chaffee, a remembrance service was held January 27 at the Kennedy Space Center's memorial Space Mirror.
