On Sept. 29, the spacecraft will swing less than 142 miles above the planet’s rocky surface for a final gravity assist that will enable it to enter orbit around Mercury in March 2011. With more than 90 percent of the planet’s surface imaged after the spacecraft’s second flyby, the team will focus instruments on questions raised by the earlier flybys to advance our understanding of the planet closest to the sun.

The briefing participants are:

  • Anthony Carro, MESSENGER program executive, NASA Headquarters in Washington
  • Eric J. Finnegan, mission systems engineer, Johns Hopkins University Applied Physics Laboratory in Laurel, Md.
  • Noam R. Izenberg, instrument scientist, Mercury Atmospheric and Surface Composition Spectrometer, Johns Hopkins University Applied Physics Laboratory
  • Sean C. Solomon, principal investigator, Carnegie Institution of Washington
