See Earth from 31 million miles away
It’s a journey I will never get to make, but thanks to NASA I’ve just seen the Earth from 31 million miles away!
NASA has made available two short videos of the moon passing in front of the Earth as seen from their Deep Impact spacecraft 31 million miles away.
“Making a video of Earth from so far away helps the search for other life-bearing planets in the Universe by giving insights into how a distant, Earth-like alien world would appear to us,” said University of Maryland astronomer Michael A’Hearn, principal investigator for the Deep Impact extended mission, called EPOXI.
The videos are indeed very short, only 20 seconds each and the Earth looks like a giant marble more than anything. In the first video (using a red-green-blue filter) you can just about make out Australia, but you get a decent view of Africa just before the moon passes by the Earth. In the second video you get a more detailed view because an infrared-green-blue filter was used.
You can watch the two videos and read more about the Deep Impact spacecraft on NASA’s website.
