Tuesday’s CSExtra offers the latest reporting and commentary on space related activities from around the world. NASA Administrator Charles Bolden pledges a traditional role for NASA’s Johnson Space Center as he visits the installation on Monday. NASA to unveil new findings about asteroids, a potential destination for future human explorers. An active sun produces geomagnetic storms early this week. A look back at the contributions made by the RTG to planetary exploration. The Draconid meteor shower peaks next week. New observations suggest the universe it expanding in an uneven fashion.
1. From KTRK-TV in Houston: NASA Administrator Charles Bolden visits the Johnson Space Center on Monday, speaking with employees and touring a mock up of the Orion/Multi-Purpose Crew Vehicle. Johnson will play its traditional role in the future, leading the MPCV design; recruiting and training astronauts; and planning and controlling missions of the new spacecraft to deep space destinations, says Bolden. The NASA center recently marked its 50th anniversary.

3. From Space.com: Major weekend solar eruptions lead to geomagnetic storms on Monday. There were no reports of disruptions to communications and navigational satellites, but experts predict brighter aurora at the north and south poles as the sun becomes more active.

4. From The Space Review of Monday: In “Planetary Exploration’s Radioactive Decay,” TSR editor Jeff Foust looks to a little known recent space anniversary. Earlier this year, the space community celebrated the 50th anniversary of the first mission using a plutonium source to provide satellite electrical power. The Navy’s Transit 4A spacecraft was a forerunner to the modern GPS navigation constellation of satellites. Compact, lightweight and highly reliable, the radioisotope thermoelectric generator, or RTG, serviced NASA’s Apollo spacecraft and a range of accomplished missions still exploring the most distant reaches of the solar system.
