I wasn’t really sure what to expect, but it was basically a bunch of space enthusiasts and people in the industry. SpaceX has a mock-up of their crew capsule, and other sponsors had exhibits with things like space plane mock-ups or geological drills. There was a life-size inflatable model of the Curiosity rover. There was a single track of programming with speakers on topics from the actual science of Martian exploration to the question of just why we explore space in the first place. Katie caught the Sally Ride tribute while I walked J around the exhibits, and we both watched Bill Nye’s talk about “Our Place in Space,” which he finished up with a fun science demonstration featuring liquid nitrogen marshmallows, gas toruses, a candle, and Robert Picardo.
The exhibits for “kids of all ages” turned out to be for kids from 4 on up. J wasn’t really interested in the Martian soil uplift demo, or the dirty snowball CO2 comet demo, but he liked watching the Xbox Mars Lander game, and he was fascinated by the robot that picked up and tossed basketballs. He had fun hanging out with grandma and grandpa, at least, and playing with a magnetic meteorite. (The tiny fragment of verified Martian meteorite was carefully mounted on a slab with plastic wrap to protect it from skin oils, but they had a couple of non-valuable rocks that you could pick up and hold.)
A family friend invited us to the after party at the mall across the street. It was divided into two main areas: the sci-fi-themed dance floor out on the plaza, and a set of tables on the terrace above for the sit-and-talk crowd, where the main event was a participatory art project: A group had set up one blank postcard for each day of Curiosity’s journey from Earth to Mars, and was asking attendees to draw what they imagined the probe would write home about.
