Exploring Mars' Ionosphere: Insights from Recent Research and Simulations

This white paper summarizes recent findings from Boston University researchers on the Mars ionosphere, featuring contributions from experts in the field. The paper reviews the ionospheric effects on radio signals, presents simulations of Mars Global Surveyor (MGS) and Mars Express (MEX) radio occultations, and discusses the implications of solar flares. Key recommendations to NASA include maintaining the MAVEN mission and extending its studies, ensuring continued exploration of ionospheric science. The results highlight critical insights that will aid in future exploration and understanding of Mars' atmosphere.

Presentation Transcript

  1. Recent results from Boston University Paul Withers and Majd Matta (withers@bu.edu) With contributions from Michael Mendillo, Anthony Lollo, Joei Wroten, Robert Pratt, Jeffrey Russo MEX Workshop 2010.01.25-26 Max Planck ISSR, Katlenburg-Lindau, Germany

  2. Overview • White paper on Mars ionosphere • Review article on Mars ionosphere • Ionospheric effects on radio signals • Simulations of simultaneous MGS and MEX radio occultations • Simulations of solar flares • NASA wants to give you money (MAVEN)

  3. White paper on Mars ionosphere Community contribution to NASA Decadal Survey, thank you to co-authors 1) Please don’t cancel MAVEN 2) Please extend MAVEN 3) Ionospheric science should not end with MAVEN

  4. GPS range error General case Chapman layer

  5. Signal attenuation results SZA = 0 degrees, OZA = 0 degrees Extend from normal ionosphere to disturbed ionosphere, including MARSIS surface blackouts

  6. 10 Dec 2005 – MGS at 67N, MEX at 36S What model parameters reproduce both observations well?

  7. Simulated ionosphere for solar flare Flare peak at 13:49 (green) Observation at 14:16 (blue) Next steps: Compare model with data Optimize model inputs Are optimized inputs like the atmosphere, electron temperatures, secondary ionization realistic?

  8. MAVEN Critical Data Products mepag.jpl.nasa.gov/cdp/ 3 page proposals due 1 March A rare case where NASA $ can flow to Europe

  9. Backup

  10. 10 Dec 2005 – MGS at 67N, MEX at 36S What model parameters reproduce both observations well?
