Slideshow: Great Space Rovers
11/20/2012

During the development of the Lunar Exploration Light Rover, BRP, a subcontractor of the prime subcontractor, MacDonald, Dettwiler and Associates Ltd., created the SL-Commander. This all-terrain vehicle is an electric version of BRP's commercially available BRP Commander. It is fully automated and can be remotely operated to drive itself at a maximum speed of 40kph (24.85mph). The SL-Commander weighs 1,100kg (2,425 pounds) and can carry a payload of 200kg (440.9 pounds). (Source: Canadian Space Agency)

Are they planned for deployment?

Ann, this is interesting, but does the CSA plan to deploy these.  I recently saw a show on PBS which went into some detaill about the Curiosity rover.  This is a large vehicle.  One thing that was interesting was the Mars Exploration Science Rover.  Your caption states that the rover is designed to collect samples to bring back to earth.  As far as I know, this is a very expensive proposition.  The Curiosity rover has the lab built in so that it can analyze the samples in place.

Lou, no decisions have yet been made on what will be deployed where. These are prototypes, so the CSA is still working out the details and trying out different approaches to similar goals.

It's a good start.  For those of us who own extraterrestrial real estate (or just think we do), the SL-Commando is appeaiing.  

The Exploratorium in San Francisco had a great exhibit about Curiosity that still has an online component.  It's so amazing!

No offense to anyone but half the stuff I see in here are not going to survive space a minute in. especially that "ruggedized computer" in image ten. I can see holes the size of quarters on it that are not sealed in any way. Take it from some one that has worked on materials that actually go to space pin size cracks that require a 10X magnifying glass to see are a problem if your insulation material is not sufficient. One more thing, those connectors just don't look space worthy. Really Ethernet? Custom sealed connectors rated for space might do the trick. Generally speaking off the shelf connectors that are rated for that environment will be cheaper than to design your own too so good rule of thumb don't try this at home.

Critiquing space rated boxes.

I looked critically at the critical note about figure number ten.    It states the rugged processor box wouldn't last a minute in space,  from "one who knows"     But the legend states the box is space rated by NASA, ESA and Nippon SA.   Who is kidding whom?

Ann--Excellent post.   Do you know if there is available information that would tell us what "on-board" diagnostic packages exist to analyze soil, air for methane, test for water, etc etc?   Is there a "standard" schedule of experiments given for probes of this type; i.e. lunar, Mars, etc?  I have taken a look at the NASA web site and don't see any specifics. (Maybe missed them.)  This would be very interesting to know.  Again, excellent post.

Ervin.  Have to agree with you on this one.  I think the mechanical drive concepts are OK and fairly well thought out but lift off and re-entry are definitely tough on components and other equipment.   I worked in the aerospace industry (Titan II Missile) some years ago and "survival" was the key word.  Generally, mission critical components and systems had redundancy.   It was amazing to me how many launches were successful due to the redundant systems after the primary systems failed.   I definitely enjoyed Ann's post and it's very interesting to see what's in the works relative to probes that might be used.

When has a prototype ever been a viable product, ready for production/use?  I think what's shown here is a good first step as we think about space colonization.

And, kind of fun to think about.

Nice to see that the CSA has other projects besides the arm that they are known for.  This is quite a variety of concepts.  I'm assuming they are platforms to test different instruments/approaches/missions rather than a "family" of rovers geared toward a specific mission.
