Wednesday’s CSExtra offers the latest reporting and commentary on space related activities from across the globe. The U. S. Air Force Space Command, in response to budget reductions, looks to closure of the aging U. S. “space fence” that characterizes objects in orbit around the Earth. Europa: A place for life? The latest on black holes, relativistic physics, quantum mechanics and everything in between. NASA’s Jupiter bound Juno mission passes the halfway point. Settling Mars means living off the land. In Hawaii, a memorable four month Mars analog mission draws to a close.
1. From Spacepolicyonline.com: U. S. Air Force Space Command warns it is preparing to close the Air Force Space Surveillance System, a network of ground-based radar and receivers, also known as the space fence, that tracks objects in Earth orbit. Closure in the coming weeks would be a response to budget reductions. A replacement will not come on line until 2017 — following the selection of a contractor. A reprieve is possible.
2. From Space.com: Europa, an ice and ocean covered moon of Jupiter, stands out with Mars as solar system bodies that may have and perhaps still host microbial life. An op-ed examines the U. S. budget tensions that are pacing efforts to develop a robotic lander mission to the Jovian moon to find out.

3. From The New York Times: Black holes, firewalls, event horizons, worm holes and the escape of information. Fascinating discussion of the debate among physicists over black holes and the implications of Einstein’s theory of general relativity.
4. From The Coalition for Space Exploration: NASA’s Juno mission, a Jupiter orbiter, reached the half-way point in its journey to the solar system’s largest planet this week. Juno’s circuitous course will bring it close to the Earth in October for a gravitational boost. Launched in August 2011, Juno should reach its destination on July 4, 2016. Juno, among other objectives, will look for a solid core hidden within the cloud shrouded planet.

5. From Space.com: Settling Mars. For Earthlings that will mean learning to live off the land.

6. From The Associated Press via The Washington Post: Six volunteers emerge from a Hawaii-based, four month Mars mission simulation.
