There's basically no point scientifically for doing the four-planet flyby again. Since Voyager, we've already done much better at Jupiter and Saturn with years-long orbiter missions. A quick flyby wouldn't get us anything we don't already know at those. Voyager gets the mindshare because it was first and the four-way slingshot is fun to visualize, but the reality is that Galileo and Cassini and Juno delivered thousan…

Going out further than Voyager might be interesting just for studying the conditions outside the inner solar system. Though I'm not sure how much there is to observe unless you go an order of magnitude faster than Voyager to try to reach the oort cloud

There are proposals for this, here's one: https://en.wikipedia.org/wiki/Interstellar_Probe_(spacecraft...

It's the Maestro from Moon Surgical, it's done over 200 surgeries, all successful. So far (no whammy) its had 100% reliability with the first 6 systems we built. We designed it (hardware wise) with only 3 engineers, including me, and we hand built the first ones right here in San Carlos, CA. The company is based in Paris and has a whole interesting history there as well.

Hold on, is that the robot that did surgery on a grape?

No, but I worked on one of those too. I worked on J&Js ottava, its designed to compete with the one doing the grape surgury, Intuitive's Da Vinci. I've had the pleasure of using one (Da Vinci XI) to play around with, it's truly amazing.

sorry, i just have a silly question: what would it take to send new probes out there? voyager 3 and 4 for example to follow the same path (more or less, sans planet alignment) V1 and V2 followed, but with better hardware of course.

If you mean just to beat them on distance, we could probably launch something capable of it in a decade or two by getting more serious about nuclear propulsion and using some slingshots to pick up speed further.

If anyone is curious about the computers they use: https://en.wikipedia.org/wiki/Voyager_program#Computers_and_...

16/18-bit custom architecture, 4k/8k words (around 9/18KB total). Other sources I could find indicate a 250kHz clock frequency and around 8KIPS.

There's something very beautiful about Voyager's journey so far. I hope one day when we're a true interstellar species we'll still keep tabs on it. The data may not be useful anymore, but it would be cool to imagine a year 3000 society with a little "Look at where Voyager is now :)" tool that you can see its path and where humans have colonized by comparison.

Oh, you sweet summer child...

This patronizing phrase should really be scrubbed from the modern lexicon.

How much data can you send in a single radio single? I assume it's not TCP/IP

Have you investigated this or are you just asking? I imagine if you wish to learn the answer it is a few simple searches away. And by “imagine” I mean, it is.

You can get raw bitrate numbers, not so much about the way transmissions are formatted.

Posting a question in a forum has its benefits though. A bunch of drive by folks end up picking up information they would never have gone through the trouble of researching themselves.

The Voyager project is an amazing feat for humanity. But I wonder, does NASA take into account the repercussions of sending a probe deep into space? I know space is big but I can only think of the dark forest hypothesis. What's the plan for further space exploration?
