GP-B Talks & Poster Presentations at the April APS Meeting

GP-B had a strong presence at the American Physical Society (APS) meeting in Jacksonville, Florida, on 14-17 April 2007. During this meeting, we emphasized three main themes:

Successful completion of most challenging space-based experiment in NASA's history
First scientific results from this historic mission
Public release of Level2 science data (via NSSDC)

Four members of the GP-B team gave invited talks, beginning on Saturday morning, April 14th, with GP-B Principal Investigator, Francis Everitt's plenary talk entitled First Results from Gravity Probe B.

On Saturday afternoon, two papers related to GP-B were delivered in Session C12: Experimental Tests of Gravity.

C12.00004: Lessons Learned from Gravity Probe B for STEP, LISA and other experiments by GP-B team members Paul Worden and Sasha Buchman
C12.00005: Proper Motion of the GP-B Guide Star by the Harvard-Smithsonian Center for Astrophysics GP-B guide star tracking team: Irwin Shapiro, Daniel Lebach, Michael Ratner, Norbert Bartel, Ryan Ransom, Michael Bietenholz, Jerusha Lederman, and Jean-Francois Lestrade

On Sunday morning, April 15th, three members of the GP-B team were invited to give special talks on three aspects of the GP-B program:

H7.00001: The Gravity Probe B Science Instrument by GP-B Co-Principal Investigator, John Turneaure
H7.00002: The Development Challenges of Gravity Probe-B—an ongoing partnership between Physics and Engineering by GP-B Co-Prinipal Investigator, Bradford Parkinson
H7.00003: Gravity Probe B Data Analysis Challenges, Insights, and Results by GP-B Co-Investigator and Chief Scientist, George (Mac) Keiser
