Space Center Houston is turning the weekend into a spaceflight-focused celebration with Astronaut Days, running July 31 through Aug. 1 from 11 a.m. to 2 p.m. The event brings together astronaut presentations, pop-up labs, behind-the-scenes experiences and interactive activities aimed at giving guests a closer look at how humans train, live and work in space.

Retired NASA astronauts Brian Duffy, Mike Baker and Megan McArthur are scheduled to take part in the weekend programming, including "Mission Memories" talks where visitors can hear firsthand stories from their careers.

Guests can also add a ticketed Breakfast with an Astronaut in the morning, featuring a catered meal by Wolfgang Puck and a live Q&A with that day's featured astronaut.
