Re: 2 billion in today's market
NASA's cargo resupply contracts and funding of rocket engines has been the single most spectacularly successful investment they have ever made in space vehicles. Crew supply contracts look like they'll yield equally impressive results. NASA didn't so much plan those results as accidentally achieve them. They didn't have a lot of money, they took a bit of a gamble and it's paid off brilliantly.
I thought the Ansari prize was wholly funded by the Ansari family.
