Is the Mars rover program a scam?
I've always been under the impression that the Mars rovers were sent up largely with the intent of seeking to discover if there is or has ever been life on Mars.
Turns out, they're not going to send this 2.5 billion-dollar gizmo that was sent to explore Mars anywhere near where there could conceivably actually be life, i.e. where there's water. Supposedly because of concern over the potential for introducing Earth microbes into the Mars ecosystem. Say what? Apparently 2.5 billion doesn't buy an explorer that's clean enough? So under what circumstances would they ever be utterly certain that anything they send up is completely, unquestionably sterile? So is this rover program another expensive bill of goods just like the shuttle was? |

... I've always been under the impression that the Mars rovers were sent up largely with the intent of seeking to discover if there is or has ever been life on Mars. Close. The goals were actually closer to finding if the conditions for life ever existed, a big part being "was there ever surface water". Now they've pretty much found there not only was, but is. Turns out, they're not going to send this 2.5 billion-dollar gizmo that was sent to explore Mars anywhere near where there could conceivably actually be life, i.e. where there's water. Supposedly because of concern over the potential for introducing Earth microbes into the Mars ecosystem. Firstly, the current rovers are far away from this location, so even if they wanted to, it's not practical. Secondly, even if they could, the rovers really couldn't do much with their equipment to find signs of life. Say what? Apparently 2.5 billion doesn't buy an explorer that's clean enough? No, not really. So under what circumstances would they ever be utterly certain that anything they send up is completely, unquestionably sterile? They can do it, but it's damn hard so they've done less levels of cleanliness. Basically the conditions required to completely sterilize a probe also are terrible for electronics. High heat/moisture is one way (think autoclave) and this can melt/damage electronics. Radiation can also be used to sterilize stuff, but again, bad for most electronics.

I'm incredulous that they can't sterilize the components before assembly and put them together in a sterile environment, and put them into sterile containment in the transport vehicle. Is it going to get any less difficult with future missions? |

Plus you're driving up the cost of assembly because that would then have to be done in a completely sterile environment. Jeff Well there you have it, it's impossible to ever determine if there's life on Mars. |
