2nd International Mars Sample Return 2018 (LPI Contrib. No. 2071) sess303.pdf Thursday, April 26, 2018 MARS 2020, CANDIDATES LANDING SITES, EXOMARS AND THEIR RELATIONSHIP TO MARS SAMPLE RETURN 10:25 a.m. Forum This session will present a status report on the Mars 2020 sample-caching rover, its candidate landing sites, the Exomars rover mission, and the relationship of all of these to Mars Sample Return. Chairs: Victoria Hipkin (Canadian Space Agency, Canada) Briony Horgan (Purdue University, USA) 10:25 a.m. Williford K. * *Jet Propulsion Laboratory, California Institute of Technology, USA The NASA Mars 2020 Rover Mission The NASA Mars 2020 rover mission will explore an astrobiologically relevant site to characterize its geology, evaluate past habitability, seek signs of ancient life, and assemble a returnable cache of samples. An overview of technical capabilities and scientific strategy in development will be presented with a focus on the role envisioned for Mars 2020 in a possible Mars sample return campaign. 10:45 a.m. Schulte M. * Meyer M. Grant J. Golombek M. *NASA Headquarters, USA The Mars 2020 Rover Mission Landing Site Candidates [#6026] The number of suitable landing sites for the Mars 2020 rover mission has been narrowed to three leading candidates: Jezero Crater, NE Syrtis, and Columbia Hills. Each offers geologic settings with the potential for preservation of biosignatures. 11:00 a.m. Vago J. L. * Svedhem H. Sefton-Nash E. Kminek G. Ruesch O. Haldemann A. F. C. Rodionov D. ExoMars Science Working Team *European Space Agency ExoMars Contributions to Mars Sample Return [#6021] Each of the two ExoMars missions has the potential to make discoveries that could inform and perhaps influence our collective strategy for a future Mars Sample Return mission. 11:15 a.m. DISCUSSION .
