JunoCam
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 )〕
Due to telecommunications constraints, Juno will only be able to return about 40 megabytes of camera data during each 11-day orbital period. This will limit the number of images that are captured and transmitted during each orbit to somewhere between 10 and 1000.〔(''Junocam will get us great global shots down onto Jupiter's poles'' (The Planetary Society) )〕 This may be comparable to the Galileo mission, which captured thousands of images〔(Galileo Legacy Site Image Gallery (NASA) )〕 despite its slow data rate (due to antenna problems).
== Design origins ==
The JunoCam physical and electronic interfaces are largely based on the MARDI instrument for the Mars Science Laboratory.〔 However, the housing and some aspects of the camera's inner mechanism have been modified to provide stable operation in the planet's comparatively intense radiation and magnetic field.〔 Part of its mission will be to provide close up views of Jupiter's polar region and lower-latitude cloud belts,〔 and at Juno's intended orbit the camera is able to take images at up to per pixel resolution.〔
