Starship would seem the natural choice to bring Vanguard home, but I wonder what else could be used. Stoke Space's Nova vehicle comes to mind as a good option.

"The spacecraft is a 1.46 kg (3.2 lb) aluminum sphere six inches (150 mm) in diameter, with antennas spanning three feet (0.91 m)"

A mission like the private EVA SpaceX missions could probably just go up and grab it. Maybe need to detach/break/bend 4 of the antennas to fit it through the hatch.

Why not go and steal the pyramids if you are all about destroying human achievements.

It has 200 years to go. In 190 years maybe give it a boost.

By all means go to view it, do some real space tourism with a scientific edge.
