Election Day may have us tied up in anxious knots today. But we can also take solace in the fact that nearly 12 billion miles away, one of humanity's greatest achievements is twinkling back at us, and our understanding of the mysteries of the universe continues to unfold....
...After a seven-month hiatus without being able to command Voyager 2, NASA is now able to communicate new directions and procedures to the craft, the agency announced.
The Voyager 2 space probe, launched in August 1977, has been traveling outward for more than 43 years visiting Jupiter, Saturn, Uranus and Neptune....

Biden 303 330. Come on man.
With all due respect.....pintos ain’t cool bro. Lol
yes
wow
different gravity-powered boosts from Jupiter and Saturn
Wow!
Can you give examples of other forms of technology like say a 28.8k modem, up to the current data speeds of 4g/5g how long the signals would take at the same distance? Thanks

So I gotta ask. Assuming an even 43 years at an even 34,000 mph, how much younger than 43 years is it?

Sorry
I LOVED this movie, watched it several times. Very humorous.

The toughest challenges were to make sure the RTGs didn't break apart if the rocket blew up on the pad, if the rocket failed to make orbit, and if it went into the wrong orbit and crashed back into earth sometime in the future. The RTGs are powered by highly toxic plutonium. There were lots of civil protests against launching the RTGs because of the risk of plutonium poisoning of a lot of people.
“American badass” — LOL...and the nicest guy you would ever want to meet! It was the most stressful job imaginable. You have an unforgiving launch window. Tens of thousands of systems and subsystems all coming together for that launch. Things in the development programs didn’t always go right and they would have setbacks that needed to be made up.
I’ve always wondered what Dad was like on the job. He had to have been a badass to get everybody to perform, but you just can’t kick butt. He was always kind and a great mentor to me.
They made the same gripes about Cassini, IIRC
Yes they did.
I remember Dad telling me about the toxicity of plutonium and how many people one little speck could kill. It was really frightening.
The Voyager Program was similar to the Planetary Grand Tour planned during the late 1960s and early 70s. The Grand Tour would take advantage of an alignment of the outer planets discovered by Gary Flandro, an aerospace engineer at the Jet Propulsion Laboratory. This alignment, which occurs once every 175 years, would occur in the late 1970s and make it possible to use gravitational assists to explore Jupiter, Saturn, Uranus, Neptune, and Pluto. The Planetary Grand Tour was to send several pairs of probes to fly by all the outer planets (including Pluto, then still considered a planet) along various trajectories, including Jupiter-Saturn-Pluto and Jupiter-Uranus-Neptune. Limited funding ended the Grand Tour program, but elements were incorporated into the Voyager Program, which fulfilled many of the flyby objectives of the Grand Tour except a visit to Pluto.Voyager 2 was the first to be launched. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune. Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, which was known to be quite large and to possess a dense atmosphere. This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. Had Voyager 1 been unable to perform the Titan flyby, the trajectory of Voyager 2 could have been altered to explore Titan, forgoing any visit to Uranus and Neptune. Voyager 1 was not launched on a trajectory that would have allowed it to continue to Uranus and Neptune, but could have continued from Saturn to Pluto without exploring Titan.
