Star Voyager

The Voyager is a tiny machine.

This model apos s parameters are expected to be confirmed or denied when the two Voyager spacecraft reach this area and transmit their data back to Earth sometime within the next decade. (Voyager 1 was launched in September 1977 and Voyager 2, in August 1977.)

It was taken by this thing, which is called the Voyager spacecraft.

What you're going to see we're going to have to jump in here pretty quickly between several orders of magnitude to get down to where we see the solar system these are the paths of Voyager 1, Voyager 2, Pioneer 11 and Pioneer 10, the first four spacecraft to have left the solar system.

For instance, the multi hundred watt RTG on the Voyager 2 spacecraft, launched in 1977, has continued to operate as it has travelled beyond Neptune into space.

And some 3,000 of those are flying. Of course, one of them is around the world Voyager. I founded another company in '82, which is my company now.

These spacecraft include the Space Shuttle and Earth orbiters planetary orbiters such as Galileo and Magellan and the Voyager and Pioneer spacecraft travelling to the outer reaches of our solar system.

And after it visited all four of those planets, Carl Sagan, who's one of my great heroes, had the wonderful idea of turning Voyager around and taking a picture of every planet it had visited.

If you look very hard here you can see the signal from the Voyager 1 spacecraft, the most distant human object in the universe, 106 times as far away from us as the sun is.
