NASA announced that Edward J. Weiler would continue in the position of Associate Administrator for the SMD. He had held the position of Interim Associate Administrator for the SMD since 26 March 2008. Joining NASA in 1978, Weiler had served as Chief of the Ultraviolet/Visible and Gravitational Astrophysics Division, Chief Scientist for the Hubble Space Telescope (HST), Director of the Astronomical Search for Origins Program, Associate Administrator for the Space Science Enterprise, and Director of NASA’s GSFC. As Associate Administrator for NASA’s SMD, Weiler would be responsible for managing research and exploration programs on a number of topics, including Earth studies, space weather, the solar system, and the universe. Additionally, he would oversee the SMD’s grant-based research programs and spacecraft projects.

For the first time since its 27 April 2008 launch, ESA’s satellite GIOVE-B transmitted navigation signals. GIOVE-B, a test craft for the Galileo global navigation system, successfully transmitted the common GPS-Galileo signal in a specific optimized waveform known as multiplexed binary offset carrier (MBOC), thus demonstrating that the GPS and Galileo systems could operate compatibly.compared to GPS, Galileo would provide deeper penetration for indoor navigation and a greater level of accuracy in environments where multipath and interference occur. ESA officials would analyze the quality of the signal to ensure that it conformed to the system’s design specification, that it did not interfere with services on adjacent frequency bands, and that the environment did not affect the signal.
