Covering a total area of 1,600 square metres, the "Hall of the Cosmos" and "Hall of Space Exploration" feature around a hundred exhibits of which over 50 per cent are of interactive design. With the aid of interesting hands-on exhibits coupled with vivid lighting effects and environmental decorations, the exhibition introduces astronomy and space science in an engaging way.

The “A Voyage to Space: China’s Manned Space Expedition” exhibition presents the country’s aerospace milestones by highlighting the journey of the country’s astronauts from training to their missions aboard the Tiangong Space Station, the achievement of scientific experiments and extravehicular activities, as well as the participation of Hong Kong in projects related to the country’s manned space programme.
