The balloon drops ballast and vents gas to control altitude. But it does that autonomously, we only need to send a downlink, if we want to have it to fly on another altitude. Also, we eventually need to support the balloon with controlling its altitude at sunrise and -set. But that shouldn’t be more than a handful downlinks per day. The balloon should send uplinks every 5 to 15 mins. Pictures would be nice, but if that is against the fair use policy (I will look up how hard we would need to compress a picture) it’s okay.
