Orbital data centers get cheaper below $500 per kilo
“in space number one we don't need permitted land so your biggest cost is gone we don't need batteries and backup power because they're 24-7 in the Sun”

Chip failures could make or break orbital data center economics
“So for StarCloud 2, we had a three-month burn-in period, it basically means you run the chips hot for three months so you can find all those failures early.”

Starcloud plans to build toward 100 satellites a week
“we'll be up to a hundred a week from what we've got here so 10 a day or more than 10 a day”
