New Tanks Arrive

The new external tanks have finally arrived in Florida. These tanks will decide whether Atlantis will be taking off in June or May. "The 154-foot-long tank now is scheduled to fly with the orbiter Endeavour on an International Space Station assembly mission later this year." But scientists would like to use the tank to replace the damaged tank currently belonging to Atlantis. The new external tank has many options for its use, the question is now...just where to use it?
