Zitat des Tages von Ellen Stofan:I'm actually a NASA brat. My father was a rocket scientist. He started working at NASA before it was NASA in 1959.
As chief scientist, it's sort of my job to look at bridges between what we do and to see the connections. But when we try to understand how are planets around other stars habitable... to looking back at the Earth - how are the changes that are taking place, how are they going to affect humanity?Ellen Stofan
