Space Inspirium

Space Inspirium is GISTDA’s public space-science museum inside the Space Innovation Park campus in Thung Sukhla, Si Racha — Thailand’s first dedicated space-learning centre. Entry runs 50 THB for adults and 20 THB for children, and it’s open Tuesday to Sunday, 09:00-16:00 (Saturdays and Sundays to 17:00), closed Mondays.

The museum is organised into exhibition zones that move from the origin of the universe through the solar system’s formation to Thailand’s own satellite and space programmes, run by the same agency that operates the country’s earth-observation satellites. Exhibits lean interactive rather than glass-case: touch-screen displays on space missions, scale models of satellites and rockets, and simulators that let you feel what different planets would do to your weight. The planetarium dome is the centrepiece — a domed screen with surround narration that runs scheduled shows through the day, worth timing your visit around if the dome format is the main draw for your group.

Insider Tip: School groups tend to book weekday mornings, so a weekend visit or an early Tuesday arrival gets you a quieter run through the galleries and shorter waits for the planetarium seats.

The museum sits inside GISTDA’s working technical campus rather than a town-centre or beachfront location, so it’s a deliberate stop rather than something you stumble on — most visitors combine it with a day exploring Si Racha or the wider Chonburi coast. It’s about 90 minutes to two hours from central Bangkok by car depending on traffic, a realistic add-on if you’re already heading out toward Sriracha or Pattaya rather than a standalone day trip from the capital.

Watch out: It’s closed Mondays, unlike most beach and temple attractions along this stretch of coast — check the day of the week before building it into a tight Chonburi itinerary.

Bring a light jacket for the air-conditioned planetarium, and plan for two to three hours to get through the galleries and a show without rushing. For more of the area, Ko Loi, the small islet temple linked to Si Racha by a causeway, is a short drive away, and the Grand Canyon flooded quarry is another Chonburi stop worth pairing with it. The Chonburi destination guide covers the rest of the province.
