That’s here; that’s home; that’s us. The image above shows what Earth looked like to NASA’s Cassini spacecraft on April 13, 2017 as it flew past Saturn’s night-shadowed A and F rings. At the time the raw images were captured Saturn and Cassini were about 889.6 million miles (1.43 billion kilometers) from Earth. From that distance our entire world—and everyone on it—is just another tiny light in the dark.
The first mission to successfully* send a rover to Mars, NASA’s Mars Pathfinder, launched on Dec. 4, 1996. It was a “budget” Discovery mission designed to demonstrate a low-cost method for delivering a set of science instruments to Mars and sent the first remote-controlled vehicle to be used on another planet. Solar-powered and only a foot in height, the little six-wheeled Sojourner was the foundation for all future Mars rovers…and, along with the Carl Sagan Memorial Station, gave us our best views of the Martian surface since the Viking 1 and 2 landers.
Got the Monday back-to-work blues? Upset by bad news headlines? Concerned about a potential future President Trump? Take a couple of minutes and watch this.
This video, published by The Royal Institution on YouTube in Dec. 2015 and shared again on Twitter today, features an adorable animation about spaceflight with narration taken from a lecture given by Carl Sagan in 1977.
At that time it had been five years since humans had last walked on the Moon, the first Space Shuttle flight was still three and a half years away and the Voyagers had only just passed the orbit of Mars. But Sagan’s confidence and enthusiasm about the future of space exploration and human spaceflight is as inspirational now as it was then…let us continue to remember his words and pass along his message to each new generation that looks up and wonders “what’s out there” and, more importantly, “can I go?”
“Artifacts from Earth are spinning out into the cosmos. I believe the time will come when most human cultures will be engaged in an activity you might describe as a dandelion going to seed.”
— Carl Sagan, 1977

A perfect accompaniment to Carl Sagan’s birthday (he would have been 77 today) here’s a wonderful music video created by John D. Boswell as part of his Symphony of Science project. Featuring Neil deGrasse Tyson, Brian Cox and Carolyn Porco, this takes you on an inspirational journey around our solar system, and reminds us – very much in the spirit of Mr. Sagan – of our place in the Universe and what it feels like to look back at our planet from oh-so-very far away.
I’m not a huge fan of AutoTune but in this case I’ll gladly make an exception.
“Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.”
― Carl Sagan, Cosmos
The Symphony of Science is a musical project of John D Boswell, designed to deliver scientific knowledge and philosophy in musical form. The project owes its existence in large measure to the classic PBS Series Cosmos, by Carl Sagan, Ann Druyan, and Steve Soter, as well as all the other featured figures and visuals. Continuation of the videos relies on generous support from fans and followers. You can make a donation if you wish to contribute support to the project.
