Cher collègue,
vous êtes cordialement invité à assister au séminaire du Dr Tony Freeman,
Earth Science Research and Advanced Concepts Program Manager au Jet Propulsion Laboratory
(JPL).
Il nous présentera en détails les 2 missions SMAP (Soil Moisture Active-Passive Mission) et
DESDynI (Deformation, Ecosystem Structure and Dynamics of Ice) qui sont des missions
NASA/JPL
Le séminaire aura lieu au CESBIO le mardi 5 février 2008 à 11h en salle de conférence (RdC)
Merci de bien vouloir transmettre cette information à celles et ceux qui pourraient être
intéressés.
Résumé :
The recent US National Academy Survey of NASA Earth Science Missions listed 15 Earth
observation missions for NASA to fly over the next decade. Four were identified as near-term
priorities, to be initiated as soon as possible, including the Soil Moisture Active-Passive Mission
(SMAP) and the Deformation, Ecosystem Structure and Dynamics of Ice (DESDynI) missions,
which are the subject of this talk. The SMAP mission carries a combined L-Band radar and
radiometer in an orbit that allows measurement of soil moisture worldwide at 2-3 day intervals,
with spatial resolution of ~ 1km. DESDynI carries a combination of an L-Band polarimetric SAR
and a vegetation canopy lidar. The presentation will provide an overview of the science return
expected for each mission, and a status update.
The research described in this presentation was carried out by the Jet Propulsion laboratory,
California Institute of Technology, under a contract with the National Aeronautics and Space
Administration.
About the speaker:
Anthony Freeman received the B.Sc. (Hons.) degree in mathematics in 1979 and the Ph. D.
degree in astrophysics in 1982, both from the University of Manchester Institute of Science
and Technology, Manchester, England.
Dr. Freeman is currently the Earth Science Research and Advanced Concepts Program
Manager at the Jet Propulsion Laboratory (JPL). JPL has a broad portfolio of Earth Science
missions as well as planetary science missions and this office is responsible for all of JPL’s
future work in this area. Prior to this position, he was section manager of the Mission and
Systems Architecture Section at JPL, responsible for all advanced mission studies at JPL and
prior to that instrument manager for the LightSAR Radar Program at JPL. His research
interests include correction of Faraday rotation, modeling of polarimetric radar scattering
signatures, and the design of P-Band spaceborne SARs.
