Stunning work, huge kudos to you, not just on concept but great execution/UI etc. My 14yo son is the most ridiculously keen space nut (the only teenager I know with a pdf of the Apollo manual on his phone) - he’s going to be very excited to see this.
I’m ex Head of Web at the Science Museum (London) and now run a company that works exclusively with museums. I’ll ping a few people: I know the curator of Space at SciM but also lots of museum web people. Just possible someone will know someone at the Smithsonian.
