Martian dust storm covers Spirit's solar panels in dust

This has proven to be a bad week for NASA rovers patrolling Mars. NASA has several rovers on the surface of Mars performing various missions including looking for water and existence of ice on the red planet.

Yesterday, NASA announced that it had lost communications with the Phoenix lander and had no expectations of the lander surviving the inhospitable Martian winter. Despite the fact that the rover has been declared dead by NASA, the Phoenix mission was a success and lasted longer than originally planned by NASA.

Today, NASA has announced that the Spirit rover is also in jeopardy of failing. Lack of sunlight hitting the solar panels of Spirit is causing serious concern at NASA. According to scientists on the mission, Spirit only produced 89 watt-hours of energy last weekend, which is half the amount of power the rover needs for full performance.

The reason for the drop in power production is a massive dust storm that deposited Martian dust on the solar panels and prevented sunlight form reaching them. Spirit's mission began in 2003 when it was sent to the red planet to search for clues on past water on the surface of the planet.

To help conserve power and prevent Spirit from running its batteries dry, NASA instructed the rover to turn off several heaters designed to keep scientific instruments warm. The rover was also ordered to stop communicating with Earth until Thursday.

NASA says that if it doesn't hear form Spirit on Thursday it will be extremely concerned. Scientists hope Spirit will make it, the dust storms over it position have abated. It's not known if the storm caused damage to any of the rover's instruments at this time or if the rover will be able to move again due to the dust on the panels.

Lady luck favours those who don't try too hard with chance.

Lady luck also favors those who are prepared. If we test it under a wide range of drastic scenarios, then we can start to really take luck out of the equation and instead it only a small chance something bad happens.

Lady Luck favors those who make reasonable assessments of risks, rather than those too afraid of their own shadow to ever accomplish anything.

Even should a complete failure occur, causing an RTG to release its radiologic package, the end result would simply be a negligible increase in background radiation levels.

We live in a constant bath of radiation anyway. If people realized this, there would be a lot less irrational fear over all things nuclear.

reasonable assessments of risks,

Speaking of reasonable assessments- as a supporter of nuclear technology, I find it hard to believe that the minority of of the public (I've seen recent polls showing 47% in favor of nuclear power, 41% against) was able to sway policy regarding Nasa's use of nuclear technology on Mars. I understand

When you consider the fact that a low recent approval ratings of current congress/executive branch as well as several years of protest by a minority in the US have failed to sway foreign policies and armed conflicts, I would say that the idea that the public has shifted NASA's use of nuclear power is not a "reasonable assessment."

Apologies for the choppy statement- I will endeavor to edit my responses more thoroughly.

A. NASA has already gone on record several times on why they've been reluctant to include nuclear power on missions.
B. The public's opinion of nuclear power has increased dramatically in the past few years.
C. The "squeaky wheel gets the grease" syndrome. A vocal minority can and does influence policy decisions in this country, unfortunately.

Too bad she doesn't kill idiots. Like drunk drivers.
