Mark Wiedenbeck

  • B.S., Physics, University of Michigan, with highest honors (1971)
  • Ph.D., Physics, California Institute of Technology (1978)

Research Interests
  • The origin and acceleration of energetic particles in a variety of space environments including on the Sun, in the interplanetary medium and the Galaxy.
  • Instrumentation development for radiation studies in space.


Solar Probe Plus Icon Solar Probe Plus
Solar Probe Plus will study the streams of charged particles the Sun hurls into space from a vantage point where the processes that produce the solar wind actually occur.

STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA's Solar Terrestrial Probes program (STP).
