Description of the payload

JPL Remote is a multi-instrumented upper atmosphere research experiment aimed to better understand stratospheric chemistry and the stability of the ozone layer. It transports a series of instruments that performs measurements of atmospheric trace species by using the technique of solar occultation mode, in which the direct Sun is viewed through the atmospheric limb thus providing long atmospheric paths and hence high sensitivity to trace species. The type and number of the instruments may vary from flight to flight but range from photometers and radiometers to spectrometers and interferometers.

The instruments are mounted in a specially built gondola measuring 6 ft. by 6 ft. on their sides by 18 ft height as we can see at left. It counts with a sun tracker that drives a rotator performing the pointing of the gondola in azimuth. Onboard are also included the NASA telemetry / telecommand system and batteries to power all the instruments. The gondola is not pressurized so to protect the instruments from cold of the stratosphere the gondola is covered in all sides and top with a canvas made of insulating material. Crush pads made of hobeycomb cardboard are fixed beneath the four bottom corners and around the upper corners of the gondola to minimize the shock of landing while below is mounted the ballast hopper, containing steel shot that is released on command to compensate loss of altitude of the balloon in flight.
