Can you tell us more, Bruce? Phil I think he was referring to the fact that this was going to be the site for the Mars 2001 lander. It might have been frustrating, but not if it landed where it did. I think Marie Curie, which would have flown on that mission, would have at least been able to explore the Eagle outcrops. And such discoveries might have allowed for MER to carry better-suited instrumentation (actually, probably not much, given the lack of time between the missions, unless one of the MERs were delayed. But for Phoneix, there is a much longer gap before the proposed drilling mission). -------------------- |

QUOTE (tedstryk @ Aug 29 2005, 09:53 AM) we need to know more about Mars' climate cycles, both over periods of just a few years and over its 150,000-year long obliquity cycles (as ice is repeatedly deposited and then removed again from various latitudes). This mission is the perfect way to do that relatively cheaply and quickly. While I agree with Bruce on the importance of these topics, there is a substantial chance that Phoenix's results will be inconclusive about both them and any biology. Just as with Deep Impact, this is a new terrain that we know very little about. Any of many factors -- like landing a few meters away from the right site or some type of soil gardening that erases context -- could prevent us from learning much about these goals. That said, I think it's worth the effort. We need to take risks and then not blame the spacecraft team if we get skunked. |

I know there are those who insist that we should send a mobile vehicle with a large drill that can also take more samples, etc., etc. Well, while we're at it, why don't we put a manned module in orbit to control the rovers in real time. And, add sample return capacity, of both soil, rock, and ice cores. Sure, there are limitations of the mission thanks to budget, but that is just reality. -------------------- |
