Love the Voyagers story.

Just get me thinking: Why there is not more missions like this ? It takes significant time to cross "somewhere there", every year one launch could not hurt ?

I don’t understand why we are not sending these off in every direction constantly. The price can’t possibly be that prohibitive considering what we can accomplish with 40 year old technology.

The Voyagers took advantage of a particularly good planetary alignment for gravity boosts.

The equivalent of about 4 billion dollars in modern day money for both of them. That, plus waiting for some very opportune launch times so that we can gravity boost off of everything.

I hope they will publish firmware/source code at some point in the future. It would be definitely interesting to look into.

I could be able to find out the code is a mix between assembly and fotran. I wonder how percentage of it is for sensor, navigation, communication

I suspect they can’t. It is quite possible security was not on anyone’s mind back then and the last thing they want are rouge signals from some amateur fucking up generations worth of work.
