What criteria do you use to decide who to attack today? How many sided are your 'attack dice'? |

As usual, you are posting without contributing anything. Wacko extremism must make discussion nasty. And that is what you promote constantly. When should we expect then next cheapshot on Obama? Maybe you could schedule these replies? Rush has a schedule. Why not you? |

After being struck in the sand for ten months, the last Spirit attempt to get out caused a third wheel failure. Ground controllers may have changed tactics. Winter is coming. Mars even on its equator is extremely harsh in the summer. In the winter, and without being able reposition, controllers are now speculating about Spirit's ability to survive this winter. So all efforts are being rechanneled into fortifying Spirit for Winter.
Spirit was always the hard luck child. Opportunity, even in development, was devoid of so many problems that plagued Spirit. Fortunately, at the highest levels of NASA, a program that was only supposed to build one risky Rover, instead charged JPL to build two in only two years. To load existing science tools (from a previous program - Athena) onto a mobile platform. Well five years later, both Rovers that were so risky, were still doing science. Like anything that gets old, Spirit is approaching death. Caps a victory that naysayers have disparaged. Spirit has maybe one more experiment. Using its radio and stationary location, science hopes to measure Mars expansion and contraction. Hoping to learn about Mars core. For example, why does Mars not have a protective magnetic core so necessary for human survival? A Spirit death watch has started. Every watt that Spirit can generate will be necessary to save it from winter's chill. Mars is that inhospitable to manned exploration. Which is why programs such as Martian Rovers are where most of our science budget should be directed - and away from political agendas that get almost all NASA's budgets. |

Let us hope for what may be after the martian winter, revel in what was 24x its expected lifespan, and look forward to its twin Opportunity which was so aptly named. No matter how one looks at this, it was and continues to be a HUGE success. |

Damn, glatt, you beat me to it!!

It wouldn't hurt if you actually had enough intelligence and wisdom to be a conservative -- but you can't get your mind around that idea either. No concept of it. It's an added deficiency. |
UG - I already responded to that - let it go, seriously - let it go.

Same questions will be asked soon about Ares 1 - a Saturn V on steroids that might need be canceled. A rocket that does what the French and Russians are already doing - for less money. Due to political agendas and White House lawyers rewriting science, America will soon have no vehicles to get to the ISS. A political agenda almost cost us Hubble. Destroyed at least eight major space science experiments that we will not profit from years from now. The death of Spirit demonstrates why success best occurs when science is not rewritten by White House lawyers. And why such successes will be less than what could have happened. Why the best science comes from robots and unmanned vehicles. The death of Spirit (like the death of George Washington) is a tribute to what does work - and why. After six years, Spirit is in a death watch. Opportunity continues. We need more science from such superior solutions – some that were canceled or delayed by decisions in the 2000s. Fundamental to many upcoming question about to be asked because after six years, Spirit may die. BTW, how much power does all that productive work? At one point, Spirit ran all sol on energy consumed in 50 minutes by one 100 watt light bulb. Both Spirit and Opportunity operate all sol on maybe 12 watts of electricity. Survival on Mars is that difficult. |

That cartoon is soooo sad. :mecry:
It occurred to me a month back - if the rovers had been fitted with vertical-axis wind turbines, they would easily survive the winter. Mars is the windiest place in the solar system, the energy generated could produce heat. Hang in there Spirit. Good luck Opportunity. Stop anthropomorphising, Zengum. |

Lowest temperature for the Rovers is -40 degrees. Spirit was below that temperature when it shutdown. Hope is that Spirit has gone into low power mode - to put all its power into keeping warm. So NASA's deep space network has been listening. Hoping that Spirit will wake up and transmit. If it can generate enough power to turn on the transmitter. And if it survived temperatures below what it was designed to withstand. |
