Tuesday’s CSExtra includes the latest on the U.S. Air Force and United Launch Alliance attempt to launch the first in a new generation of GPS satellites. Shuttle Atlantis to surpass the 120 million mile mark before a planned return to Earth early Wednesday — weather at the Kennedy Space Center permitting. Today marks the opening of the two-day Exploration Enterprise Workshop in Galveston, Texas. In other developments, NASA ends efforts to communicate with the Phoenix Mars Lander and NASA’s educator-astronauts reminisce.

1. From Spaceflightnow.com: A last second countdown hold late Monday halts the the lift off of a Delta 4 rocket with the first in a new generation of GPS satellites.  The hold involves an issue with the steering system on the Delta’s solid rocket boosters. Further launch attempts will await the landing of shuttle Atlantis.

2. The Atlantis astronauts surveyed the heat shield of their space ship on Monday and checked out the steering systems early Tuesday, as the orbiter’s final scheduled mission draws to a close. Landing is set for Wednesday at 8:48 a.m., EDT. The outlook includes a chance of showers on Wednesday and Thursday at the Kennedy Space Center in Florida.

3. From the Los Angeles Times: NASA’s Mars Phoenix Lander, last heard from in 2008, remains silent in a just ended search by the space agency for signs of recovery from a harsh winter at the probe’s Martian north pole landing site. A new photo of the lander suggests solar panel damage from an accumulation of winter ice.

10. Two from Monday’s The Space Review on the nation’s future space policy:

A. Twin hurdles for commercial space flight. Editor Jeff Foust examines the debate over the transition from NASA/government to commercial crew launch services. Perhaps too much burden has been placed on Elon Musk and SpaceX to succeed with the inaugural Falcon 9 flight, which may take place as late this week. Further into the article Jeff Foust examines a range of other issues, including whether “commercial” is really commercial when the market at the moment is NASA.

B. The View from Austin on commercial space. Jonathan Coopersmith, a historian of technology at Texas A&M, writes on the issues policy makers are beginning to address with the new emphasis on commercial space. One of the largest seems to be a change in perspective, away from a mission centric view to an applications centric view of space exploration. The global annual space commerce market is now estimated at $260 billion. The transition has “fractionated” the space community, as some are faced with job loses in order to create new opportunities for others. Some of the losses mean a loss of expertise and experience in the difficult field as well. Jonathan Coopersmith draws his assessment from the Space Economic Leadership Conference of early May.
