Expedition Center Program Reservations

Step 1: Decide if you want to go to the Expedition Center at HMNS or at the George Observatory.
Both centers are managed by the Houston Museum of Natural Science and have similar programs.

A Expedition Center Program at the Museum includes admission to the Permanent Exhibit Halls and all the other venues are available at discounted school rates. HMNS is located near Hermann Park, central to everyone in the Houston area.

The Expedition Center at the George Observatory is located in Brazos Bend State Park, rated one of the top 10 state parks in the nation. Other activities can be added to a mission at the Observatory, such as astronomy classes and a visit to the large telescope. A day in Brazos Bend Park can be very educational in a relaxing atmosphere.

Step 2: Choose a mission option that fits your group.
Several expedition options are available at both centers. Full, Mini, Jr., Advanced Mini, Advanced Full have been developed to fit different age groups.

At the George Observatory, astronomy classes can be added on to your mission to make Mega Expeditions.

Step 3: Pick at least 3 days that will suit your schedule for your field trip.
Some parts of the year are busier than others, therefore the amount of time you should register in advance will vary.

To book a field trip for the fall, you should book as soon as school starts. Because of state testing and spring break, March and early April are a good time for home school groups and private schools to book and only a few weeks advanced registration is required.

Late April and May are the busiest time of the year so registration should be made several months in advance. Generally there is higher demand for Wednesdays, Thursdays, and Fridays.
