Its so cool that the entire solar system has a sort of ozone layer (the heliopause), I also really like the diagram that shows how each craft is travelling in different directions.

I think we should have a new mission, send out huge amounts of tiny crafts in all directions at the same time, to get a sort of Google street view of our solar system and interstellar space. I bet we could create crafts with modern tech that where tiny and much less expensive that the original pioneer and voyager crafts.

It's harder than you'd expect. At that distance solar panels are essentially useless, so you do need nuclear power, and you're continuously exposed to cosmic rays, so you need radiation-hardened electronics. Both of these drive up the cost. The Voyagers also had the the outer planets in alignment to give it a gravity assist, so if you want to get there on the same time scales you'll need a more powerful rocket as well.

I read somewhere that sending very small spacecraft to far away places was something that was being considered. Unfortunately I don’t remember the details. We just need an artificial gravity machine.

Tiny spacecrafts and sails with lasers. Yeah pretty sure that was it. Such a cool idea, and it would only take 30 years, which means a lot of us will still be alive to see it. Imagine seeing actual closeup pictures of “earth 2”.

Anyway if they used the same technology, but sent spacecraft out into space from locations all around the Earth at the same time, then we could gather data as this fleet headed into deep space.

Like one of those big planet explosions in science fiction movies, but instead of an explosion, just tiny space crafts.

There's no way to get a gravity assist in directions orthogonal to the solar plane, which makes travel in those directions either far more expensive or far slower.

I hadn’t thought of that, but your totally right. In the article’s picture, one of the space craft appears to be heading off in a direction outside of the solar plane, but it’s not by a huge amount.

That’s why we need a way to create gravity artificially if we are going to do any space exploration. It would be a bit crap if we could only move in 2 dimensions.

That might be our best bet to get to other systems. But it’s still pretty much a fantasy. The engineering challenges behind that project just seem insurmountable unless we work on it as a planet, not just NASA, ESA, Roscosmos, etc.

It doesn’t sound that hard, it’s just laser kites. I bet Elon could do it.

Apart from the insane amount of power required to use lasers as propulsion in this way, they also require a camera, computer, interstellar communications system and nuclear power source within a mass budget of a few grams. It's complete science fiction.
Re:Voyager 1 hears the hush of interstellar plasma by mjgs on Tuesday May 11, 2021 @06:18PM (#27124297)
Literally everything in this area starts out as science fiction. I think the general idea of sending lots of small craft is a good idea. It would be great to hear from the people building these things which parts are not possible currently.

Given the crazy high amount of laser power this requires, maybe placing a satellite close to the sun, and having it focus solar radiation, would be better than an earth based laser grid?

> you do need nuclear power, and you're continuously exposed to cosmic rays

silly question: can CRs be harnessed for power?

The Gaia probe is doing something a little like this to create a full 3D star map. It rotates as it goes and uses parallax to measure the distance and motion between stars exactly.

Google street view of our solar system

Has anyone ever updated Commodore's Visible Solar System? Very inspiring.

Street view in space? I think you might be underestimating just how empty the solar system is.
Re:Voyager 1 hears the hush of interstellar plasma by mjgs on Tuesday May 11, 2021 @08:02AM (#27117035)
Of course it’s not exactly like street view!

But it is a sort of map, ok probably Google maps rather than street view :)

So it should be quite easy to build.

Maybe it's like Star Trek and space is full of anomalies even 24th century sensors miss.
