Last Wednesday, Oct. 9, 2013, NASA’s Juno spacecraft made a slingshot pass of Earth in order to get the necessary speed boost to reach Jupiter in 2016. As it came within 347 miles of our planet’s surface, passing closest over the southern Atlantic at 3:21 p.m. EDT, it used its JunoCam (developed by the San…

Cassini Snaps a Picture of Earth from 900 Million Miles Away
So did you get out and Wave at Saturn on The Day the Earth Smiled? If you did (and even if you didn’t) here’s how you — and everyone else on Earth — looked to the Cassini spacecraft in orbit around Saturn, 898.4 million miles away.* As Carl Sagan famously said, “That’s here, that’s home,…

Our Electric Earth at Night: the “Black Marble”
In daylight our big blue marble is all land, oceans and clouds. But the night is electric. This image of North and South America at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012.

Blue Marble, Pale Blue Dot…whatever you call it, it’s Home
35 years ago today, September 18, 1977, NASA’s Voyager 1 spacecraft turned its camera homeward just about two weeks after its launch, capturing the image above from a distance of 7.25 million miles (11.66 million km). It was the first time an image of its kind had ever been taken, showing the entire Earth and Moon together…
Goodbye, Earth!
