For the balloon to be floating, they must be in the upper atmosphere not in space. Also, “weightless” doesn’t happen unless you are falling. (“In orbit” means you are falling off to one side so fast that you constantly miss hitting the planet.)[“Weightless” can also happen when you are too far from any planet to feel its gravity very much.]
