Future Tense

In a video with the bleak title “We Stopped Dreaming,” astrophysicist Neil deGrasse Tyson makes the case for space exploration—and not just because it may help us find a new planetary home someday. “We went to the moon, and we discovered Earth,” he says, tying the famous photograph Earthrise to the birth of the environmental movement and even Doctors Without Borders—because, he says, it was the first time we saw the planet without “color-coded boundaries.”

The video promotes Penny4NASA, a campaign calling for NASA’s budget to be doubled to 1 percent of the U.S. budget. (It’s currently about 0.5 percent.)
