Interplanetary Laser Trilateration Network short course poster


Program:

Talk 1 – "Interplanetary Laser Trilateration Network" – Bruce Bills, JPL

  • Overview of Interplanetary Laser Trilateration Network
  • What are some chief science questions & challenges related to ILTN?
  • What measurements are needed to address these questions?
  • What is the relationship between: cadence of observations and accuracy of tie to center of mass of host planet?


Talk 2 – "High-Precision Solar System Dynamics with Improved Interplanetary Ranging" – Konstantin Batygin, Caltech

  • Overview of orbital dynamics in the solar system, emphasizing the role of chaos on both short timescales (planetary scattering) and long timescales (stability boundaries identified via high-precision numerical integrations).
  • The significance of asteroidal chaos in limiting the predictability of planetary orbits.
  • Potential of interplanetary ranging networks to detect unseen objects in the outer solar system.


Talk 3 – "Laser Ranging Beyond Lunar Distances" – Evan Hoffman, NASA Goddard Space Flight Center

  • The history and current state of ground-based satellite laser ranging network infrastructure
  • What models do we use to predict single-shot and normal point (averaged) precision and accuracy?
  • What do past and current 2-way (round-trip) and 1-way (dual laser/clock) laser ranging missions teach us about the engineering challenges of an ILTN?


Talk 4 – "Enabling Planetary Missions with ILTN" – Andrea Donnellan, Purdue University

  • ITLN characteristics
  • Planetary science goals that would benefit from ITLN
  • ITLN as infrastructure versus discovery-based mission
  • Requirements development
  • Community engagement
  • Advocacy and proposals


Talk 5 – "Future of Solar System Science with ILTN" – Mike Watkins, Caltech

  • How have the measurements for understanding Solar System Dynamics evolved over the past 50 years? 
  • What has the combination of flyby's, orbiters, and landers taught us so far about planetary orbital dynamics and planetary internal structure? What drives the limits of our current understanding?
  • Highlights of particular missions and measurements (planetary ephemeris development, gravity, seismometry, altimetry) 
  • How does ILTN continue that evolution?
