NASA Still Has A Lot Of Work To Do

NASA's space shuttle program is now over, but the clean-up is just beginning, USA Today reports. The space agency is preparing to clean up "toxic viscous goo" left behind from decades of space shuttle, moon mission and rocket launches around Kennedy Space Center. The goo is seeping into groundwater and has contaminated at least two square miles of soil. The clean-up efforts will take decades and cost the agency hundreds of millions of dollars.
