NASA MOVES SPACE STATION REPAIR SPACEWALK TO SATURDAY

HOUSTON -- The first of two spacewalks by NASA astronauts to replace a failed ammonia pump on the International Space Station has been moved to Saturday, Aug 7 A second spacewalk is planned for Wednesday, Aug 11, to complete the repairs

Teams of flight controllers, engineers, and spacewalk experts have made significant progress in preparing for the first spacewalk, but need an additional day to get ready The additional time allows for final procedures to be sent late Thursday to the station, giving the crew a full day to review the plans developed by Mission Control Managers also moved the second spacewalk to Wednesday to give the crew more time to rest and prepare

Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson are scheduled to perform the spacewalks, which will air on NASA Television Coverage will begin at 5 a m CDT The spacewalks are scheduled to begin at 5:55 a m Saturday's spacewalk will be the fourth for Wheelock and the first for Caldwell Dyson

Approximately two hours after the conclusion of each spacewalk, NASA TV will broadcast a briefing from NASA's Johnson Space Center The briefing participants will be Mike Suffredini, International Space Station program manager; Courtenay McMillan, Expedition 24 spacewalk flight director; and David Beaver, Expedition 24 spacewalk officer

Johnson's newsroom will be open for credentialed reporters to attend the briefing Johnson also will operate a telephone bridge for reporters with valid media credentials issued by a NASA center Journalists planning to use the service must contact the Johnson newsroom at 281-483-5111 no later than 15 minutes prior to the start of a briefing Phone bridge capacity is limited and will be available on a first-come, first-served basis

Engineers and flight controllers continue to review data on the July 31 pump failure, which caused the loss of one of two cooling loops aboard the station This failure resulted in a power down and required adjustments to maintain as much redundancy as possible for the station systems The systems are stable, and the station's six crew members are not in any danger

MEDIA INVITED TO NASA�S DESERT-RATS PRACTICE RUN IN HOUSTON

HOUSTON � Area reporters are invited to experience life on an extraterrestrial surface, without leaving their own hometown

The engineers, scientists and technicians who travel annually to Arizona for a simulated exploration mission as part of the Desert RATS � or Research and Technology Studies � tests are preparing for the September field tests by putting on a practice run in the Johnson Space Center Planetary Analog Test Site � also known as the rock yard Reporters who won�t be able to make it to the field tests in the desert can see the next best thing between 9:30 and 11:30 a m on Wednesday, Aug 11

Interested news media representatives should e-mail Brandi Dean at brandi k dean@nasa gov by noon on Aug 10

The Desert RATS tests offer a chance for a NASA-led team of researchers from across the country to come together to conduct technology development research The location of the actual field tests is chosen for its similarity to possible destinations for future planetary exploration missions

That allows those planning the missions and designing the equipment to be used during them to determine what works and what doesn�t, before astronauts travel hundreds of thousands, or even millions, of miles from home The practice runs in NASA�s rock yard � which include a large hill, a rock- and boulder-strewn field and three simulated impact craters � allow the engineers and scientists a chance to make sure they�re ready for the tests before they�ve traveled thousands of miles from home

The NASA hardware that will be seen during the practice run includes:

• Space Exploration Vehicles � a pair of rovers that astronauts will live in for seven days at a time in Arizona
• Habitat Development Unit/Pressurized Excursion Module � a simulated habitat where the rovers can dock to allow the crew room to perform experiments or deal with medical issues
• And a suite of new geology sample collection tools, including a self-contained GeoLab glove box for conducting in-field analysis of various collected rock samples

The media opportunity to be held in Arizona at the test site will be on Sept 15 More details on that will be available soon
