Wednesday’s CSExtra offers the latest reporting and commentary on space related activities from across the globe. The moon appears to harbor an interior water source of its own, scientists report. Russia and Europe to discuss future cooperation in lunar exploration. Radiation exposure limits mean more U. S. men than women fly on space missions. Russia considers export ban on powerful rocket engines used by United Launch Alliance Atlas 5 for military and civil space missions. International Space Station astronauts recreate space suit water leak that halted July 16 U. S. spacewalk as part of new troubleshooting effort. NASA’s Curiosity rover navigates a short stretch of Martian terrain on its own for the first time. SpaceX looks to a Vandenberg Air Force Base, Calif., launch late this year for test of Falcon 9 reusable first stage. Singer Jimmy Buffet remembers NASA’s Neil Armstrong.
1. From The Los Angeles Times: The moon harbors an indigenous source of water, according to findings from India’s 2008 Chandrayaan-1 mission. The findings, made with NASA instrumentation, promise to build on those from rock samples brought to Earth by NASA’s Apollo astronauts. The Indian mission carried out 312 days of a two year mission.
A. From Space.com: Moon’s water source likely deep within the moon’s interior, say scientists. Conclusions, so far, based on findings from NASA’s Moon Mineralogy Instrument flown aboard India’s Chandrayaan-1 mission spacecraft.

2. From Itar-Tass, of Russia: Russia and the European Space Agency to discuss further cooperation in lunar exploration. At first, ESA’s participation will be modest, according to a European space official.

3. From Space.com: Radiation exposure concerns limit women more than men from flight assignments aboard the International Space Station as well as prospective future deep space missions. The limit for both genders is an accumulated exposure that would not increase their life time risk of developing fatal cancer by more than 3 percent. However, exposure limits are about 20 percent lower for women than men because of the breast, ovarian, and uterine cancer risk, the website reports.

4. From Russia Today: Russia’s Security Council considers a ban on the export of RD-180 rocket engines to the U. S. The ban could have a major impact on Atlas 5 missions launched by the U. S. military as well as NASA. While it may object to use of the engine hardware to launch military hardware, Russia may have difficulty finding alternate export markets for the powerful RD-180.

5. From Spacepolicyonline: Astronauts aboard the International Space Station recreate the worrisome space suit water leak that brought a July 16 spacewalk by European Space Agency astronaut Luca Parmitano to a halt. The suit was activated Tuesday by Parmitano and his spacewalk partner Chris Cassidy. The test set the stage for further troubleshooting focused on identifying the source of the water seepage.

6. From NBC News: NASA’s Curiosity Mars rover steers for brief stretch under its own guidance for the first time. On Mars for just over one year, Curiosity is headed towards the base of Mount Sharp in Gale Crater.

7. From Space News: SpaceX looks to a Falcon 9 launch from Vandenberg Air Force Base, Calif., late this year to test parts of its future reusable first stage. After separation, the first stage will attempt maneuvers for a safe water landing. The Falcon 9, 1.1 upgrade, will carry a Canadian satellite as its primary payload.
8. From Collectspace.com: New Jimmy Buffet album recognizes Neil Armstrong, commander of NASA’s Apollo 11 mission. Released this week, the new albums track The Rocket That Grandpa Rode honors the first human to step to the surface of another world. Armstrong died on Aug. 25, 2012.
