The TXMOST Discovery Dome mobile planetarium comes to you! Instead of reserving a school bus, our astronomy educator will travel to your school or event venue, and set up our mobile planetarium. The Discovery Dome is available throughout the year on a first come first served basis. We are available Monday through Sunday from 8 am to 9 pm. Note that there is an added fee of $75 for appointments after 6 pm and on weekends.

The planetarium dome holds about 45 children (plus two adults) or 30 adults per show. We provide the dome, all visual and audio equipment, and an astronomy educator. During the school day, each TEKS-aligned show usually lasts 45 minutes, including time to enter and leave the dome. For evening or public events, we have shorter presentations of 20-30 minutes.

The TXMOST Discovery Dome mobile planetarium needs to be set up inside, in an area at least 25′ x 25′ x 13′ high.
