In September 2015, the Leisure and Cultural Services Department announced that the two exhibition halls, which had been in use since 1991, would undergo renovation beginning on 5 October that year. The renovated exhibition halls would be renamed "Hall of the Cosmos" and "Hall of Space Exploration" respectively. Visitors would be offered a novel experience in which they could learn about the evolution of the universe, the exploration of the solar system and beyond, and more. The renovation was finally completed in 2018, and the exhibition halls reopened on 25 April that year.
