Spotting Tornadoes From Space
Description	This feature, part of the NASA KIDS site, describes the need for an instrument that will be better at predicting tornadoes. During last year's tornadoes in Oklahoma, a NASA satellite called the Tropical Rainfall Measuring Mission (TRMM ) looked at six of the supercell storms, but it only got to watch for about 90 seconds, because it was traveling so fast. What scientists want now is to watch thunderstorms from a satellite that stays over the same spot on the ground.

Read about storms at sea in this National Geographic Eye in the Sky News article.
