The questions will be dumb. they will repeat again and again. That's because not everybody is an expert on Mars robotics. Everybody has daily tech and they just use these tech as comparison points.
For instance, people have everyday technology in hands and they believe, if the ordinary Jane/John Doe has a multi core processor smart phone costing them 1000$ with manufacturer margin, NASA/ESA/JPL whatever guys with millions of dollars of funding has to use better and faster and fancier hardware. And by being ordinary John/Jane Doe, fancier does not mean "radiation hardened", "autonomous in hostile environment", "updatable on slow and relayed links". Because these are not their daily problem. They do not know about them. Also if Apple/Samsung/Motorola heck even Nokia guys could design and mass manufacture, and distribute any smart phone in a few months to be held on john's or jane's hands, NASA must be a fricking snail fast. How distant could Mars be? I can transport from continent to continent in a few hours?
Don't be harsh on them.
Some of the questions may seem dumb, but may be really good questions if they are worked on. For example, I believe radiation hardening is needed because while transportation to Mars there is massive amounts of radiation to be moved through. If the Curiosity would not be operated in the journey, and Mars radiation levels are not that massive. Could Curiosity use multiple (with spares of course) faster and cheaper ordinary processors with small energy footprint, if the transportation was inside a radiation hardened armor that would be gotten rid off on the Mars surface?
- ctrlaltesc 14y agoJust to answer the example: Mars does not have a magnetic field of significant strength. Curiosity needs shielding on the surface. Perfectly reasonable question though.
- fsniper 14y agoSorry but I could not understand the shielding on surface. What is this shielding for?
- Two9A 14y agoRadiation, such as cosmic rays and solar flare output. The Earth has a magnetic field which pulls such charged radiation to the poles; Mars has much less of that effect.
- nicholassmith 14y agoOn Earth due to our magnetic field and outer atmosphere the radiation that gets fired at us constantly is massively reduced, on the surface of Mars the rover still needs to be shielded against radiation as there's nothing similar to protect it.
