| Tests on Earth to Help Free Spirit Rover on Mars: Live Webcast, Chat The team that operates rovers on Mars is using a test rover in southern California to assess maneuvers the Mars rover Spirit might use to get out of soft, loose soil where its wheels have sunk hub-deep. A live videocast and chat from NASA's Jet Propulsion Laboratory, Pasadena, Calif., will give viewers a chance to ask questions of rover team members working to get Spirit rolling again. The live event will air on the "NASAJPL" channel available on Ustream Web TV at: http://www.ustream.tv/channel/nasajpl on Thursday, July 23, beginning at 3 p.m. PDT (6 p.m. EDT and 2200 UTC). Spirit and its twin, Opportunity, landed on Mars in January 2004 for what were planned as three-month missions to study sites on opposite sides of the planet. Both are still active and returning streams of scientific information. Spirit has not driven since May 6, 2009, when it had become partially embedded in the soil. To minimize the risk of worsening Spirit's predicament, operators decided to conduct a series of experiments with a test rover before driving Spirit again. |

Boeing Team to Develop Revolutionary Spacecraft Power System for DARPAHUNTINGTON BEACH, Calif., July 1, 2009 . An industry team led by The Boeing Company [NYSE: BA] has received a contract from the Defense Advanced Research Projects Agency (DARPA) for work on Phase 2 of the Fast Access Spacecraft Testbed (FAST) program. The $15.5 million cost-plus-fixed-fee contract is currently funded to $13.8 million. DARPA.s FAST program aims to develop a new, ultra-lightweight High Power Generation System (HPGS) that can generate up to 175 kilowatts . more power than is currently available to the International Space Station. When combined with electric propulsion, FAST will form the foundation for future self-deployed, high-mobility spacecraft to perform ultra-high-power communications, space radar, satellite transfer and servicing missions. Boeing Phantom Works of Huntington Beach is leading the effort with support from Boeing Network and Space Systems, El Segundo, Calif. The Phase 2 work will include designing, fabricating and integrating test articles, performing a series of component-level evaluations and running two full-scale system tests. .Our team is pleased to partner with DARPA in developing this powerful new technology,. said Tom Kessler, FAST program manager, Boeing Advanced Network and Space Systems. .FAST offers significant cost and performance benefits to our commercial, civil and national security customers, including new high-power applications to provide a cost-effective means for spacecraft to travel to the outer solar system.. |

  NASA Launches 'Free Spirit' Web Site for Stuck Mars Rover
NASA's Jet Propulsion Laboratory has launched Free Spirit, a Web site dedicated to keeping track of the agency's efforts to free the stuck rover on the surface of Mars, Space.com reports. NASA currently has an entire team of engineers working to simulate the rover's predicament using a test rover and several tons of simulated Mars dirt.
"People really like the whole 'free Spirit,' idea and we thought we should make it really easy for people to find updates," said Veronica McGregor, a NASA spokesperson at JPL, in the article. "In a way, we're trying to make it a campaign that everyone can get involved in."

NASA: Space shuttle fueling test looks successful CAPE CANAVERAL, Fla. (AP) . A fueling test on space shuttle Endeavour uncovered no worrisome hydrogen gas leaks Wednesday and paved the way for a launch in a week-and-a-half for the delayed mission, NASA said. Last month, potentially dangerous leaks of hydrogen gas thwarted back-to-back launch attempts. Early Wednesday morning, launch controllers filled the external fuel tank again to see if repairs plugged the leak. No abnormal leaks were detected during the three-hour test, and preliminary results indicated the repairs were successful, NASA spokeswoman Candrea Thomas said. That means NASA can shoot for a launch attempt on July 11. Endeavour is set to deliver one last piece of a Japanese space station lab. |
