The Tucson Children’s Museum has built a new exhibit called Sense of Place. It is a fun and educational area, with interactive models of well-known areas in Tucson for kids to play on and explore. These include replicas of Sabino Canyon, Colossal Cave, A Mountain, and the “Greetings from Tucson” mural. Building the Sense of Place exhibit took about 4 months, however, planning the exhibittook about eight months. It cost about $200,000. We spoke with executive director Michael Luria and lead discovery guide Ellie Mark.
On Dec. 3, the OSIRIS-REx went into orbit around the asteroid Bennu, 241,000 to 209 million miles away from Earth (depending on its orbit). OSIRISREx is a spacecraft created to gather the largest sample of solid outer space material since the Apollo missions from 1969–1972, when the moon rocks were brought to Earth. For now, it will be scanning and mapping the entire surface of Bennu, which is 500 meters in diameter. The engineers’ planned method to make contact with the asteroid is called Tacsam.
