: Why haven’t we sent more deep space craft like Voyager 2 out? Technology has become much better over the years, so why haven’t there been new a long distance deep space craft?

The Voyager probes were getting a lot of funding and were rushed out due to a very favorable alignment of planets which meant we could send out a single probe (or in this case two for redundancy) to multiple planets. These aligments of the outer planets is quite rare and only happens about every second century. So it made sense to spend a lot of resources on something that were way ahead of time. Since then our probes have been much more reasonable in terms of budget. However they have been able to take advantage of more modern technology. We have revisited the planets and moons that the Voyager probes visited with better instruments and more time. And currently we have New Horizons which did a flyby of Jupiter, Pluto and Ultima Thule and is aiming to flyby more objects in the Keuper belt if the opperutiny presents itself. It is already studying several of the structures that the Voyager probes discovered at the edge of the solar system.
