After the simulators, we broke for lunch at Building 3, the JSC cafeteria. By then, all 30 of the tweeters were power hungry, meaning we all needed to recharge our phones. The rest of the day, any time we paused in a tour, people were looking for plugs and trying to power up. Many ran out of power before the end of the day. There was also a small gift shop, but as soon as I walked in, they announced it was time to go.
On the public tour, they advertise eating at this employee cafeteria as the place astronauts eat. Sure enough, Mike Massimino walked by our table.
