mbstone writes "MSNBC is reporting that NASA is threatening to mothball the International Space Station unless Russia coughs up its share of the money for maintenance and support missions. NASA is now making "contingency plans" to leave the station unoccupied for as long as a year. What I want to know is, why a contingency plan? Didn't NASA already have a plan in place? Are U.S. taxpayers going to pay millions extra to develop new mothballing equipment and procedures that could have been designed-in at far less cost?? Also, I would be glad to house-sit, I use very little oxygen."
