After 37 years, Voyager has fired up its trajectory thrusters

I have a truck that barely started this morning, and it was running YESTERDAY.

It has, in fact, moved beyond our Solar System into interstellar space.

Well, not exactly. The edge of our solar system isn't well-defined just yet. Instead, it passed through a region of our solar system called the heliopause where solar winds from our Sun and interstellar winds reach an equilibrium. The spacecraft is now in a region of space dominated by interstellar winds, but it is also in a region of space still dominated by the Sun's gravity.

In fact, the Voyager I spacecraft is only 141 AU from the Sun, but the Oort Cloud (a region of space that contains some of the most distant objects still orbiting the Sun) is roughly between 50,000 and 200,000 AU. Voyager I won't reach that milestone for a few hundred thousand years.

Exactly. What kind of thing sits around idle for nearly 4 decades and then just works when you try it out? Nothing you'd buy off the shelf at Wal*Mart, that's for sure.

Got space for this in your back yard?

yeah thanks. was wondering more specific about how they communicate with it. i know that there was an article on this subreddit when the programmer dude retired and they were searching for some assembler programmer that could work with this super old tech.

I've always thought the edge of the Solar System should be defined by gravity, not by radiation pressure. Gravity is the important force at the scale of star systems.

Maybe we can set it to the Sun's Hill sphere, or some fraction of it? The Solar System should contain every body in a stable orbit around the Sun. It's kinda weird that we would put the Oort Cloud outside the system.

Thanks for sharing that info. I've tried to follow v1 most my life and find it really fascinating but your Oort cloud distances are really interesting. There used to be a website that had real time telemetry and distances of v1 and v2. No idea if its still around and didnt know the Oort cloud was that far away.

Not sure if this is what you are looking for but you can read reports here (bottom of the page).
