An important mission for astronauts in space is to conduct all kinds of experiments in microgravity. Why do they need to do experiments in space? It is because there is always the influence of gravity on Earth, rendering it impossible to understand phenomena in microgravity, such as the shapes of flame, the distribution of blood in human bodies, and alloy that cannot be perfectly made. For these, space experiments can provide valuable data.

In this space lab set up onsite, visitors get to know various experiments that astronauts conduct in space through the video.
