The purpose of the Arkyd is to discover NEOs. Right now there are no low-cost, mass-produced telescopes in LEO, and asteroid discovery is driven by government-funded projects centered around universities. The compelling advantage of this telescope is that it circumvents the cost and bureaucracy necessary to discover asteroids. Of course, the kickstarter/public relations aspect is not essential to all this, but Planet…

Did you hear about b612 foundation? they also want to discover NEOs with a space telescope, and they don't want to do it for business purposes. last time I've checked they said it's going to cost about $450m to do it. There is no chance that PR will be able to do it much cheaper. They may be able to launch their toy and snap some pictures but I don't think they will be able to do much more with it.

B612 wants to make a big telescope and put it in an orbit very far from Earth. PR's approach is different - make many small, cheap Arkyd telescopes and take advantage of economies of scale. They don't want to concentrate resources and risk in a single large object.

Building a small satellite is quite affordable, but commercial launch costs are a problem. There are several funded kickstarter projects whose goal is to deploy one or more satellites in orbit for much cheaper than what PR is trying to raise.

People also overestimate the difficulty of finding asteroids. Asteroids are still being discovered by amateur astronomers on Earth. It's estimated that there are millions of undiscovered objects. A big space telescope is an advantage but not a requirement.

I think they are just running a really cool scam. First of all why do they care if public is interested in space? Aren't they after all, looking to run a successful and profitable business? Second, don't they have investors that could sponsor this Arkyd Telescope and launch it without need for a Kickstarter. What if for some reason the kickstarter campaign doesn't work? What if they can't deliver? Are they willing to…

Disclaimer: I'm at the launch event and helped put this project together. They're not doing this for the Kickstarter money. Even though they're fundraising for the project, they're already putting in more than they could ever hope to raise on Kickstarter. This project is adjacent to their core mission of Asteroid Mining, this is to prove interest that the public is interested in this sort of project, and to give the…

> For $25 you can get a picture of yourself in space. That's pretty crazy.

Well... A picture of a picture of yourself in space.

If this works, the amsat.org people should kickstart a fundraiser to get the legendary geosync sat up there. I'd be happy just with AO-40 redux, or a fleet of FM ez sats. Or maybe the mythical mars sat.

Honest question: Could you explain a bit more this topic? I don´t even know how to google it beyond geosync satellite.

Some google targets would revolve around amsat phase 4 p4 phase IV.

P4 is a little ambitious so it oscillates over the decades between active and shelved. About two cycles ago it led to phase 3 rev D P3D or whatever aka AO-40 which launched a bit more than a decade ago.

As far as kickstarters go, the AO-40 launch would be kinda ambitious, I guess just the launch alone was five million or so. The boost engine blew up, screwing up the orbit and destroying some uplinks/downlinks, then years later further related failures blew out the DC power bus, and that was it.

Now build like 3 of them and launch them and you're almost guaranteed that at least 2 would work... Just bad luck for AO-40.

There has sporadically been talk of a P5 which would be an interplanetary payload.

I've watched this stuff from the outside for a couple decades, being all volunteer its very cat-herding.

One thing I miss (dating myself pretty severely) is the Russian HF band satellites, requiring no fancy hardware on the ground and no ground computer support. I used to listen to RS-10 morse code telemetry on ten meters using basically normal ham radio shortwave gear, then there was a complicated little decode algorithm to convert raw data into actual data.

Another thing I miss is there are/used to be FM voice "easy sats" requiring pretty basic VHF/UHF FM gear. Very popular. Need more of those. I believe there's only one working ezsat in orbit right now and the hope is the FOX-1 project will deliver another working one later this year.

I also miss the high altitude / 12 hour pass Molinya orbit sats. Thus requiring fancy gear, but the highly elliptical orbits meant you could talk for hours instead of 10 minutes horizon to horizon.

So there's a lot of stuff to google for.

Ham radio is a fun, big hobby. Life's too short to actually do or try everything possible even in just the narrow confines of satellite operation, much less everything else.

This seems mostly to be a PR gimmick. While it seems like a cool thing to do "just because we can", there is no compelling advantage to putting a 200mm telescope in space. You don't get much sharper images by being in space with such a small aperture. And launching a space telescope for people to take pictures of themselves... I don't even know where to start.

The compelling advantage is that they're making it available to the public to use.

The public is already allowed to use the Hubble. You just have to send a proposal that is compelling enough for them to grant you time on the scope.

While I'm not going to dispute this, I do disagree with it.

These goals aren't distinct. What's hard for people to remember is that running a successful and profitable business is a means. It's a how; the real question is what the end goal is. For a painfully large number of businesses, the goal appears to be making the CEO rich. But some groups, some CEOs, some businesses have goals that a lot of us would consider better: actually advancing humanity forward or providing quality service or the like.

Can you give us a rough sense of scale of how the $1 million from the KickStarter compares to the other costs required to bring to completion 1) everything promised in the KickStarter, and 2) their first satellite in space capable of scoping out NEOs?

From my understanding, the $1M pays for a launch. They have already developed (or are still developing) the telescope satellite. If they exceed $1M, they may launch multiple satellites.

Do you really think that they will be able to upload a picture, display it on a LCD, snap picture of their setup and send it back to Earth and do it hundred of times with a prototype full of untested tech?

Yes.

a) The vast majority of satellites are "prototypes." They're built a few at a time, extensively tested, then launched. In the case of satellite frameworks like Cubesat, they're open source and tested every time someone launches one.

b) This is not untested tech, at all. Cubesats have been using consumer technology in satellites extensively, both by startups, hobbyists, and academia (doing advanced stuff like orbital reconfiguration, atmospheric sampling, telecommunications, etc). Combined with NASA's existing suppliers for aerospace grade components, these satellites which have a really high success rate.

I could be talking out of my ass here, but with the amount of money that's been pumped into PR (> $1B USD IIRC) by its big-name founders, why do they need to do this? Satellites are cool and all, but everything I see out of them is just "YOU GET INVOLVED" and "SOCIAL" - and not much on "How do we capture and capitalize on mineral resources in space?"

could some 100s of those small telescopes be used with interferometry to get a better picture?

In the optical wavelengths offline interferometry is currently not possible afaik.. so you have would to directly combine the signals, which I deem implausible to do in an non-lab setup, as you have to align the paths (from the individual telescopes to the interferometer) to a fraction of the wavelength.

But what I'm saying is the public can just get a 200mm telescope on the ground themselves. No need to launch it into space.

Atmospheric interference makes it impossible to observe in some wavelengths on the ground.
