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

The Discovery Dome is available throughout the year on a first come first served basis. For this reason we suggest you call or email us first to set up a tentative date. Mobile planetarium appointments must be set up at least 2 weeks in advance. We are available Monday through Friday from 8 am to 6 pm. There is an added fee of $75 for appointments after 6 pm and on weekends.
