Mary Beth Wilhelm: Commander

Mary Beth works in the Planetary Science Branch at NASA Ames Research Center and recently graduated from Cornell University with a degree in Earth Sciences and a concentration in Planetary Science and Geobiology. At Cornell, she was the Science Team Project Manager for the Violet Satellite Project and completed an undergraduate thesis studying modern day stromatolites. She has been working at Ames since she was 16 and has participated in many projects since, studying Martian gullies, crater ejecta on Mars, and working on the Pavilion Lake Research Project. This is her fourth crew as Commander at MDRS (previous crews: 73, 86, 87).  In her free time she likes to surf, do ballet, and travel and has a passion for Mars, NASA, geology, astrobiology, and exploration. She is planning to start her PhD in Geological and Planetary Sciences in the fall.

David Willson: Executive Officer

David is a mechanical engineer with some 16 years experience in industry. He is currently a senior mechanical project engineer for Tenova SEMF, a division of Tenova, an Italian based world wide engineering company that designs and constructs mobile equipment and materials handling facilities for mines and ports. He is the principle contact for issues associated with his discipline in the company for Australasian region and has design managed projects of up to $30 Mg including the concept development of a $45 M project.

David’s roles and work have included: project manager, design manager of multi-disciplined design teams, concept designer, feasibility studies, cost estimating, detailed design, tendering and writing contracts, supervising fabrication and erection, commissioning manager & engineer, the writing of manuals and training operating and maintenance personnel. Technical disciplines covered include structural and mechanical design, hydraulic and pneumatic systems design, materials handling design and software functional descriptions and system commissioning.

David has also partaken in industrial research and development projects. These include project manager for engineering work on a $14 M research & development mineral processing plant funded by Intec Helleyer Metals and the lead mechanical engineer for a $1m research and development project for a new type of ship unloader using a synchronized winch ‘drag line’ system.

Finally he has co-authored and published space related papers and undertaken field expeditions with planetary scientists to the Australian Flinders Rangers, the Californian Mojave desert in 2005, 2009 and 2010, Utah desert 2011 and the Pilbara 2011 During this period he also developed and tested Mars sample core drilling equipment for NASA Ames and field tested a space suit.

Noah Warnke: Health & Safety Officer

Noah Warnke is an undergraduate at Cornell University. He is majoring in computer science and minoring in astronomy. His interest in space exploration, and in particular planetary science, began with the landing of the Mars Exploration Rovers in 2004. He is especially interested in the applications of computing and machine learning to the challenges posed by space exploration. At Cornell he has worked with the Violet Microsatellite Project's science team, helping come up with, and assess the feasibility of, science missions for a small, high-agility satellite being built by his team-members. During the past two summers he has taught programming classes for middle- and high-school students in his hometown in Vermont. He also has extensive experience with outdoor operations, including leading hiking and climbing trips for new freshmen at Cornell and successfully completing a 340-mile road hike across a large section of the Northeast.

At MDRS, Noah will help coordinate the management and analysis of data being produced in the field. He will also serve as the Health and Safety Officer. In addition to aiding in the crew's primary mission of conducting a thorough analysis of local endolithic communities and their immediate environments, he plans to perform some visual astronomy with the Musk Observatory and obtain images of the surrounding geography for possible later computer analysis. 

When not in full science nerd mode, if Noah is outdoors, there is a high degree of likelihood that he is hiking, flying kites, or exploring old-growth forests. If he is indoors, he can probably be found playing the piano, reading science fiction and fantasy books, programming computer games and graphics rendering software, or exercising his creativity through writing or digital art and music.

Raechel Harnoto: Chief Biologist

Raechel Harnoto is a student at California Polytechnic State University studying Molecular and Cellular Biology and Music. She has interned with the Planetary Science and Astrobiology division at NASA Ames Research Center and participated in NASA's Spacewardbound Program. Her research interests include: extremophiles, metagenomics and bioremediation. This fall, she plans to pursue a Ph.D in Microbiology and continue to study Astrobiology. In her spare time, Raechel enjoys rock climbing and line dancing. 

Bradley Davis: Chief Geologist

Bradley Davis is an undergraduate student at Cornell University. He is studying Earth Science with a concentration in Ocean Sciences. His interest in planetary science began with his interest in geology and was solidified when he took an astronomy class with Steve Squyres (The Mars Rover P.I.) while at Cornell. He has participated in several field programs, including a semester-long Earth Science program on Hawaii Island through Cornell, SEA Semester-which is a semester long Oceanographic Research 

Cruise aboard a tall-ship, and a field course in Germany studying the Ries Impact Crater. He has done research with the Naval Research Laboratory concerning the Chemistry of Sea Water, interned with the Department of Agriculture in Hawaii, and spent six-months on a trail crew in the Adirondacks.


Other than science, Bradley has a passion for traveling and the outdoors. He just finished trekking the Annapurna Circuit in Nepal a few days ago.

Chris Haberle: Chief Engineer

Christopher Haberle graduated from Oregon State University with a degree in geology in the winter of 2010, an exceptionally cold winter. In the time since his graduation he has been working as a contracted researcher at NASA Ames Research Center. His research involves rock glaciers and debris-ice mixtures on earth as an analog for Mars, coring ice-debris mixtures such as permafrost, drilling with electric currents, investigating phototropic response of microbialites in freshwater lakes, extreme temperatures in Death Valley, softball and preparing various data logger and sensor deployments. He is a Gemini, enjoys the outdoors and happens to have a twin brother.
