we also have a really engaging experience from the tinkering school.d project that uses the engineering and the problem-solving that's being done by nasa at this really large, crazy scale, brings it back down to earth, and uses materials that we're familiar with to try to do some similar problem-solving and engineering. and then, we also have an experience in our wattis studio using videos that nasa has created or that persy has collected from mars as well as documentation from the launch of perseverance and the engineering of perseverance. ♪ >> so, at the exploratorium, we have a full-scale model of the perseverance rover. you're able to see the instruments on the rover as well as what the wheels look like and experience what it might be like for the rover on mars, in terms of size and scalability. it's the size of a small car. >> what i think is really great about this model is you see it in front of you. and you also can learn about each of the instruments that are on the model and learn what each of them are doing on mars. >> we're interested in as
