Didn’t they also get a few older (Hubble type) spy satellites to use? I remember a story about that.

My hazy memory is that the NRO offered NASA a few satellite bodies that they could populate with optic systems. Since they were originally designed for monitoring earth they aren’t well suited for capturing data at much longer distances. If I recall correctly I think someone explained that it’s like trying to peer through a straw, it works, but ideally you’d want a much wider field of view. And apparently the James Web telescope handles this much better.

The NRO satellites actually have an optical design with a larger field of view than Hubble does. One of the NRO spacecraft busses is being use for the WFIRST / Nancy Grace Roman space telescope because of the wider field of view.

This is a truly stellar wit.

But in all honesty, how would an internet across the solar system work?

Slowly.

There's open efforts to work on a protocol that would work with the extreme latency and packet loss. They're really quite fascinating.

Comms to rovers etc use store-and-forward protocols with pre-planning of when which node will be able to see which other node. (E.g. it's calculated when which dish on earth can send a signal that will be seen by a probe around e.g. Mars, and then when the probe can downlink to a rover on the surface, and when the replies can be transmitted)

Look into "Delay-tolerant networking" for more details.

> how would an internet across the solar system work?

Realistically, each ~150 ms sphere would have its own cloud infrastructure. Those systems would then bridge with one another. So idk AWS on Earth and DogeNet on Mars.

I would love for a distributed model as much as the next guy, but it's unlikely to happen for the same reasons that it isn't happening today.

More than 150ms. There are currently satellite internet services that you can get that use geosynchronous orbits outside of that 150ms zone.

The idea is sound, but the zone needs to be a bit bigger in reality. I think the moon is close enough to earth to be in the same zone (assuming antennas on "both sides", and special routing protocols to deal with day/night cycles)

Re:NASA can't figure out what's causing computer issues on t... by tomrod on Thursday June 24, 2021 @11:28AM (#27619008)
But if each node communicated within its 150ms sphere, and you place nodes 10ms (3,000 km?), could this serve as a mesh network?

I think you have an interesting idea, but might not be thinking of the physics involved.

> The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.

Loosely, the speed of light is ~300,000km/s. So 182s, 1333s, and 750s as an absolute minimum length of time from end to end.

So, there are varying orbits, that's one problem. The other problem is getting items into solar orbits.

I didn't think of this, but now you have an even bigger problem of trying to keep those items in some sort of array that is in a direct line between Earth<->Mars.

If we hand-wave away that problem, the next problem is that each hop is adding latency, so, the direct answer is: no, it makes things slower, and it's a significantly harder problem than just communicating across that distance.

Re:NASA can't figure out what's causing computer issues on t... by tomrod on Thursday June 24, 2021 @06:05PM (#27624449)
Array? Nah, just a very dense distribution :)

But I appreciate the thought you put into this. Thank you!
