2. Presentation Overview

  • A (brief) history of the Visual Monitoring Camera (webcam)
  • Operating VMC Webcam on Mars Express
  • Public Outreach on other Inter-Planetary missions
  • Re-commissioning Process for the Webcam
  • Public Outreach with VMC on Mars Express
  • VMC Observations so far
  • Developments in VMC Planning & Operations
  • Future for the VMC Webcam on Mars Express
  • Lessons Learned

3.

  • Development of the Visual Telemetry System on Ariane 502 (OIP Sensor Systems, BE)
  • First flown on XMM-Newton
  • Used on Cluster in 2000
  • To capture mechanism deployments: visual telemetry
  • 640 x 480 pixels, 8-bit sampling, Bayer filter for post-processed colour images
  • Design life weeks/months

1. History of the VMC 4. 2. Operating VMC webcam on Mars Express

  • No routine use foreseen
  • Evolving operational concept
  • Complex observation planning
  • Not in Science planning process
  • lowest priority
  • Best-effort basis (no cost!)
  • Non-interference basis with Science instruments

5. 2a. Beagle-2 Deployment

  • The original intended (and successful) use of the VMC, to capture the release (and spin-up) of the Beagle-2 lander, 19 December 2003

6. 3. Public Outreach on Planetary Missions

  • Mars Student Imaging Project (THEMIS, Odyssey NASA, ASU)
  • HiWish: Public pick pixels on Mars HiRise on MRO, UoA-LPL/JPL
  • Cassini scientist for a day program (target selection SOWG)
  • Saturn Solar Opposition events 2008 whole World looks up to the Sky
  • Main instruments on MEX not appropriate to public target identification?

7. 4. Re-commissioning VMC

  • Started late 2006 make new instrument from an old sensor
  • First exposure tests camera still works!
  • Process automation
    • Special pointing required (and new ones added)
    • Procedure refinement to minimise commanding
    • Pointing timeline insertion & constraint-checking tools
    • VMC Toolkit development

8. 1 stLight a new beginning for VMC

  • VMC Re-commissioned at Mars 26 - Feb-07
  • first light
  • Vallis Marinaris, taken 8-Oct-08
  • 4 volcanos, Tharsis bulge, 5-July-08

9. 5. Public Outreach with VMC on Mars Express

  • Images down-linked from Mars Express as lowest priority
    • but raw source images made available on website with minimum latency possible (VMC toolkit)
  • Blog format with calendar showing latest observations and contributions

10. 11. Clouds on Arsia Mons Image credits:ESA/NASA/JPL/Malin Space Systems/Mike Malaska Estimation of cloud height by topographic features Estimation of cloud height by shadow length 12. Composite images: clouds and dust-storms

  • 1 stVMC limb targeting observation (fixed inertial attitude rather than true tracking)
  • Images are post-processed composites of about 10 VMC shots (H.Griebel, M.Malaska)

13. 14. Latest examples: Sophisticated image processing

  • NEXT SLIDES
  • Flying over Mars: Mosaic by Errol Bruce(below) set of images from low-altitude observation on 12 Jan 2010, as MEX flew away from Mars
  • Flat-fielding Rick Hollar,Vallis Marineris & Tharsis Montes .
  • Ted Stryk, Powell, TN, USA from 24-Mar-2009 (below)

15. 16. 64 Views of Mars

  • Emily Lakdawalla (Planetary Society) has produced a composite of 64 of the best VMC images
    • She has also runs web workshops as tutorials for the general public on how to process VMC images

17. Phobos Shadow Transit across Mars 18. 6. VMC observations summary

  • Beagle-2 departure
  • 1 stImage of Mars, 1 stlow-altitude shots
  • Clouds from VMC
  • Low-altitude limb-tracking (Mars atmosphere)
  • flat-fielding techniques
  • High-Dynamic Range (HDR) processing
  • 64 views of Mars poster
  • Phobos shadow transit of Mars

19. 7. Current Developments in VMC Planning & Ops.

  • Automation of VMC pointings
  • VMCToolkitfully-automated
  • Target-pointing tools
  • MAPPS observation planning
  • Tuning to Mars Express seasons

20. 8. The Future for VMC Webcam on Mars Express

  • Keplers orbital elements education movie (~200 shots)
  • Public-input to pericenter target selection (2011)
  • Refine operation modes to avoid conflicts/constraints
  • Feedback/integrate into overall ESA Science Communications Plan

21. 8a. Public Outreach Adopt a VMC observation

  • Exploit webcam opportunity for education outreach
  • More direct involvement of Schools and Universities in ops.
  • Enhance planetary education cooperative projects
  • Generate interest in ESA and VMC web content
  • Low/minimal operations cost (telecon, e-mail support, blog publication)

22. 9. Lessons Learned on Public Outreach

  • Building Trust
  • Managing expectations
  • Data availability
    • "If I'm asleep and you're awake, you can see the pictures from the rover before I do, it's really enabled people to share in this voyage of exploration. Steve Squyres, MER PI
  • Know your limits
  • Managing the website /Blog

23. 9a. Lessons learned future missions

  • Plan for long-term use of all resources on the spacecraft, however small!
  • Exploit auxilliary payloads to augment public outreach
  • VMC has far wider uses than ever imagined (climate, science, etc.)
  • Impact on public awareness & support for robotic planetary exploration?
