2.3.1 spase://CNES/Instrument/CDPP-AMDA/MESSENGER/MAG MAG Magnetometer 2016-10-18T00:00:00Z The magnetometer (MAG) on MESSENGER is a three-axis ring core fluxgate magnetometer mounted on a 3.6 m boom in the anti- sunward direction. The detector sampling rate is 40 Hz and readout rates are selectable from 0.01, 0.1, 1, 10, 20, or 40 Hz. Averaging intervals can be selected from 0.025 to 1 s. Digital filters provide selectable bandpassed channels of magnetic field variation. spase://SMWG/Person/Brian.J.Anderson PrincipalInvestigator MAG site at JHU_APL http://messenger.jhuapl.edu/instruments/MAG.html NSSDC Master Catalog http://nssdc.gsfc.nasa.gov/nmc/experimentDisplay.do?id=2004-030A-07 Magnetometer 2005-08-02T00:00:00Z 2015-04-30T00:00:00Z Earth flyby 2005-08-02 1st Venus flyby : 2006-10-25 2nd Venus flyby : 2007-06-05 1st Mercury flyby : 2008-01-14 2nd Mercury flyby : 2008-10-06 3rd Mercury flyby : 2009-09-29 Mercury arrival : 2011-03-18 spase://CNES/Observatory/CDPP-AMDA/MESSENGER
