In the present paper, the bubble behavior in subcooled pool boiling of FC-72 on a plain plate used a quasi-steady heating method has been studied experimentally in microgravity aboard the Chinese recoverable satellite SJ-8. Based on the analyses of the number density, size and velocity of bubbles, and the nucleation process, the influence of subcooling and heating history are discussed. It's found that bubbles glide on the heating surface throughout the boiling process. They collide with each other and coalesce to form the bigger coalesced bubble. The bubble growing velocity decreases with the increase of subcooling.
