JunoCam (or JCM) is the visible-light camera/telescope of the Juno Jupiter orbiter, a NASA space probe to the planet Jupiter launched on 5 August 2011. It was built by Malin Space Science Systems.
JunoCam is not one of the probe's core scientific instruments; it was put on board to increase public engagement, and all images will be available on NASA's website.
Due to telecommunications constraints, Juno will only be able to return about 40 megabytes of camera data during each 11-day orbital period. This downlink average data rate of around 325 bits per second will limit the number of images that are captured and transmitted during each orbit to somewhere between 10 and 1000 depending on the compression level used. This is comparable to the previous Galileo mission that orbited Jupiter, which captured thousands of images despite its slow data rate of 1000 bits per second (at maximum compression levels) due to antenna problems that crippled its planned 135,000 bit-per-second communications link.
