Answer to #1 -- They still have the MRO and ESA stll has the Mars Express to help tell them these things. Plus, I bet even the Poenix lander saw the
bigginnigs of the dust storm. But the dust isn't the problem ask much as the darkness of winter is.
#2 -- There are power plants available that use radioactive decay to provide power, but Phoenix doesn't have these and used solar panels instead --
most likely for budget reasons. NASA must fight for every dollar it gets and it probably didn't get enough money for Phoenix to include radioactive
decay power generators.
...and it isn't only the dust storm that killed Phoenix; the fact that winter is cloing in -- and the Phoenix is located near the North Pole -- means
that there is very, very little sunlight to power the solar generators.
Back to money and NASA's budget (because that is the REAL reason these missions are limited)....don't forget if they planned on the mission running
for years, then they would need to pay all of the people back at NASA to run the mission for years -- and that again costs more money than NASA is
given by congress. NASA needs to show strict (and cost-effective) budget numbers to Congress before money is appropriated, and ways to do that is to
limit the length of a mission, and put relatively low-cost equipment on the probe.
The University of Arizona, who ran the Phoenix mission, was involved in an intense competition before winning the award -- and they won partly because
they said they could do it for $325 Million. They, too need to have a definite "End date" to a mission for budgetary reasons.
NASA asking congress for $325 million is much easier than them asking congress for the $750 million or $1 Billion dollars some other missions have
cost. If they didn't keep costs low, they proably wouldn't be given enough money to send a probe to mars every two years like they have been doing,
and hopefully will continue to do.
Oh...and one more thing...
Why the heck is this on the "Alien and UFO" forum? Shouldn't it be on the "Space Exploration" forum?
