Voyager 1 officialy exits the Solar System

[Fort Fun Indiana]

Here is an interesting puzzle about the Voyagers. They are slowing. Nobody understands the physics of why they are slowing.

Everyone understands it... interactions with dust, and small particles in space, while infrequent, happen. Each of these robs the Voyagers, which are coasting, of forward momentum.

They are also still doing work to escape the gravity of the solar system. Doing work takes energy, which is robbed from their kinetic energy .

True as well, the gravity well of our sun extends out past the Oort Cloud. The voyagers still have a long way to go before they're truly free.

Well, in that case, what can we call free? The gravity law is an inverse square function (I think) in its canonical form, which never goes all the way to zero. So, are you saying that the NASA people were able to calculate in the 1970s a propulsion, which at some distance coasting from the Sun will still leave a kinetic energy which is greater than the Sun's gravitational every at that distance?

Fking awesome!

If you think about it, the technology is so rudimentary.

Hard to believe it's still alive and able to communicate.

The computer was definitely made by a woman.

But we do not even know that it is truly in intersteller space .
Initially NASA told us it was, but it had ony travelled in to the Heliosphere.And that was 2013.

This has slowed the craft because of gas , dust etc and it is claimed by some that something like Voyager One can never get through this effective barrier at the edge of the solar system .It ceased communicating sensibly several months ago.

Is NASA telling the truth ?Is it unable to move further out and its equipment is slowly being degraded by radiation ?

If Voyager One is stranded against an impenetrable wall , is this the equivalent of the Firmament that is referred to in ancient script ?
No escape ?
