Before we go into the details of this article, take another look at the photo of the meteorite above and make sure you see the children. I missed them the first time. That meteorite is known as the Willamette Meteorite and it can still be seen in the Hayden Planetarium* at the American Museum of Natural History, where it has been since 1906.
In the article, astronomer Mary Proctor (whose articles for the Times Magazine have graced this site before) discusses panspermia, the idea that life can spread throughout the universe carried on meteors and asteroids.
The first time I heard about panspermia, my mind was blown. I hadn’t considered that life could have come here from somewhere else. But it makes sense as a possibility. And if meteors can theoretically bring life to our planet, that means we can theoretically send life to other planets. Wait a minute! What if those first crafts we sent to Mars weren’t completely sterile? What if we sent a germ, bacteria, or other microbe capable of withstanding space travel and Mars’ atmosphere? Perhaps over the next hundred million years it could evolve into something more intelligent than us!
