We welcomed Dr. Farrand back to the show to talk about Opportunity’s 10th anniversary on the surface of Mars, Mars rovers in general and Martian science.  During the first segment of our 1 hour 37 minute discussion, Dr. Farrand was asked about 10 years for Opportunity effective Jan. 24 and to why he thought Opportunity was still going strong after ten years.  He gave credit to the JPL engineers that designed and built the rover and those that keep the systems going.  We talked about the loss of a few of Opportunity’s instruments over the past ten years plus the current science being done by the rover.  We also talked about its path to Endeavour Crater.  In response to one of my questions, Opportunity has traveled about 38 KM since it first landed on Mars ten years ago.  He also said the science was as exciting today as it was when Opportunity first started.  Listen to how he described the rover’s evolution with science and its work over the past decade.  From time to time, other Mars rover science questions and comments came up, especially related to comparing Curiosity to Opportunity.  Our guest was asked about Earth analog sites for Mars, then water on Mars.  Cathy asked how they kept the solar panels clear of dust for maximum solar power to the rover.  He said they rely on Martian winds to dust off the panels.  We also talked about bandwidth communications and the use of the Deep Space Network (DSN).

In the second segment, we talked about our guest’s, www.farrviewconsulting.com plus the pictures posted on the site. We also talked about the special rover exhibit now underway at the National Air & Space Museum in Washington, DC.  You can see some photos from the exhibit along with a picture of our guest on the website.  As you will hear, some of the photos in the exhibit were taken by Spirit before it suffered its untimely demise.  Bill was asked several questions about technology advancement from rover to rover and Mars in general.  Later, we talked about humans on Mars, the use of Phobos, and then Doug called in to ask if it was worth the cost to put humans on Mars given how many more rovers we could put on Mars for the cost of just one human mission.  As the program was ending, Dr. Farrand summarized his thoughts on ‘Oppy” and ten years, again giving a shootout to JPL engineers.  He said the outcome of Oppy was paradigm shifting!  The final question was from Sally asking about Martian fossils.  Don’t miss Bill’s final comments regarding this question.

Guest:  Dr. William Farrand.  Topics:  Mars orbiters and rovers, multispectral & hyperspectral remote sensing data.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed Dr. William (Bill) Farrand to the program to discuss Martian multispectral & hyperspectral remote sensing data, the same for the Earth and throughout our solar system.  To find out more about Dr. Farrand and his work, please visit his website at http://farrviewconsulting.com.  In the first segment of our 90 minute discussion, we talked about the Mars solar conjunction, what the rover Opportunity is doing during the conjunction, Opportunity’s longevity, and why Spirit quit working.  We also talked about Curiosity, then I asked our guest about both multispectral and hyperspectral remote sensing data for Mars.  Dr. Farrand explained the imaging and the instruments in addition what we learn about Mars and other solar system objects through the remote sensing instruments providing us with this data.  In fact, in response to a listener email, our guest talked about remote sensing data from the Messenger, Cassini, Dawn, and other missions.  I asked our guest about minerals on Mars and throughout the solar system and how they might differ from the same mineral here on Earth.  Doug sent in a question about trades with the science missions as compared to doing a human spaceflight mission.  Our guest expanded the discussion to include very expensive science missions as opposed to more missions but lower in cost.  Dr. Farrand talked about the proposed commercial space missions to the Moon, Mars, and for resource utilization.  He also talked about the prize system as being a good way to further commercial exploration and development.  A listener asked about getting timely data released to the public.  Our guest directed us to the Planetary Data System which houses all the mission data, usually about six months after it was first obtained. 

In our second segment, Doug asked that if Curiosity comes up empty, might that seriously put life on Mars into doubt?  Don’t miss the response, it might surprise you.  We then discussed Curiosity and what it was up to at this time plus more on Opportunity.  As for future Mars missions, we talked about Maven and then our guest was asked if the current Mars science and robotic missions were designed to pave the way for an eventual human spaceflight mission to Mars.  He said they were not so tightly linked but it’s a discussion you will want to hear.  Our questions then changed to NASA economics and sequestration as our guest was asked for his thoughts on cutbacks, sequestration, moral, etc.  I asked about Earth remote sensing and we talked about Landsat satellites and Landsat 8.  Also the commercial World View 2 and the coming World View 3.  We talked about buying commercial data as opposed to using government sourced data, plus AI, real time data acquisition and more.  Near the end, Karen asked about the role the scientist plays in designing & developing the satellites & tools on board it.

Guests:  John Batchelor, Dr. William Farrand,  Dr. David Livingston:  Topics: Ten years with the Mars rover Opportunity.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com.

Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com.

During our 11 minute plus discussion with Dr. Farrand, we celebrated ten years of the Mars rover Opportunity exploring and doing science on the Red Planet.  Opportunity has outlived its fellow rover, Spirit, has traveled about 22 miles and been engaged in some amazing discoveries and research.  Our guest talked about the instruments that are still working, those that have quit, what it is finding and how it can compliment Curiosity.  We also talked about the demise of Spirit and how that happened.
