I agree that it you can fold it up, sure, go for a bigger mirror. But widening the mass constraints will also be a game changer. As for the commercial market, I think it opens up a new branch of materials science for high-end manufacturing by making zero G financially accessible. E.g. growing crystals or perfectly spherical things. If you or I already knew exactly how that would be valuable, we'd already looking for seed investment ;) Also, let's conservatively estimate its payload to be 50 tons and triple the target launch cost to $30 million. That's $6000 per 10 kgs. If there's a regularly scheduled flight to Korea/Japan, how many manufacturing and mining operations that are offline for want of a critical part would be willing to pay upwards of $6000 to take delivery of a 10 kilo part in <24 hours when they're losing a few thousand dollars per minute?
