I'm building this! Minus the "computational methods" magic... Because as someone has already commented, there are significant issues with just merging the telescope data together with computational magic.
With the advent of SpaceX's Starship providing a 100% (and the 100% is crucial to the economics of this project) reusability there is significant potential to reduce many of the costs that normally increase the price of a satellite. From not throwing away a $10,000 PPOD (cubesat deployer) to the myriad cost savings available when you know the next flight is cheap and you don't need to buy a $500 part, where a $50 or even $5 part would do the job, due to the different risk profile in many smaller satellites, compared to a few larger ones.
> Instead of building one huge short life-span spacecraft, why not launch hundreds or thousands of lower cost, less capable birds incrementally? You can start with a small "first light" capable instrument with a dozen or so spacecraft, then over time and more launches put up more and more capability and decommission failed or low capability pieces.
Thats the basic plan in a nutshell. Start small, build up, from the ~10cm primary mirror "phase one" prototypes, to eventually using ~50cm primary mirrors. Steady progress using a standardised telescope "chassis" for each generation, with each having a specific camera/instrument rather than the common (for space telescopes) practice of having complicated multi-instrument optical pathways.
Think Planet Labs, but facing out at the universe, not down towards the ground, and a non-profit/charity not a commercial company.
I'll spare the whole spiel that I've regurgitated into grant proposals (space costs money and it would be nice if I didn't have to pay the entire $250,000 or more out of my own pay-check over the course of a decade) if you want to know more (or just talk about it, or offer to help, or whatever else at all) you can contact me directly (email in my HN profile) or wait till I publish the eventual website later this year, I'll be sure to post a Show HN once I have pretty pictures of hardware.
