NASA finds new and interesting ways to waste money - has plans to make giant space ark
You need to up your reading skills a bit. A 'Space Ark' is not being planned by NASA. The article has morphed two stories (NASA has plans to colonize the moon, and the ARC (not NASA) who are advocates of preserving and backing up various aspects of our civilization.\
Notice that the title of the (linked) article is "Moon Base Announced by NASA", and careful reading will reveal that in no way are they planning to build a 'Space Ark'. Instead, you just use a casual read to reinforce your views that NASA is a waste of time and money.
Jim Burke (formerly of NASA but now with the ISU) says "This calls for the creation of a space age Noah's ark". Not NASA. Let me repeat that: NOT FUCKING NASA!
Your one line summary is inaccurate, biased and politicized statement that misinterprets the facts badly.
