Voyager 1 stops communicating with Earth

Looks like once you escape earths orbit at 11km/s, you still need another 30km/s delta-v to then escape the solar system

I thought it was 12 km/s. 30km/s is what’s required to fall into the sun, which is considerably more than escaping the solar system.

Why do we need any additional speed to escape the solar system?

Because the Sun has its own gravity well you need to get out of. Lots of things could be fast enough to escape the pull of the Earth but not the Sun (like all the other things besides Earth that orbit it)

I love the fact that one of them has launched radially and another tangentially, it will be interesting to look at the orbit of each Voyager when they finish a full rotation around the Sun.
