Mars Rover Equipment: Materials & Physics

AI Thread Summary
NASA's Jet Propulsion Laboratory provides detailed information on the materials and physics involved in the Mars Rovers, such as Opportunity and Spirit. The rovers were initially designed for a 90-day mission due to the harsh Martian environment, which poses challenges like extreme temperatures and dust accumulation that can affect their functionality. The materials used in the rovers include lightweight alloys and specialized composites to withstand these conditions. Physics principles are applied in their design for mobility, energy efficiency, and communication with Earth. Understanding these factors is crucial for anyone studying the engineering behind Mars exploration.

I'm doing a research paper <again> and I need information on the Mars Rovers (Opportuniy or Spirit or both) and what materials make up those rovers and how physics is applied there etc...im really just starting to learn physics so i don't know much
 
Physics news on Phys.org
OK, I have a question: Why, oh why, are the rover's designed for 90 day's? What IS the problem for them not going on for much, much longer? Seems bizarre to me.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
