One example includes an altitude control system arranged in a balloon. The system includes a transparent outer chamber configured to receive incident infrared radiation. The system also includes an inner chamber comprising suspended particles configured to change the optical transmission of the inner chamber between a first state having a first transmissivity and a second state having a second transmissivity. The first transmissivity is greater than the second transmissivity. The system further includes a state controller configured to electrically activate the suspended particles to change the optical transmission of the inner chamber from the first state to the second state to change an altitude of the balloon based on the incident infrared radiation.
