The Dynamic Ionosphere CubeSat Experiment (DICE) is a scientific mission consisting of two
Miniaturized SatellitesDICE-1 and DICE-2 flying in formation.[1] The satellites are an unusual 1.5U variant of the
CubeSat design for microsatellites. Both satellites were launched from
Vandenberg Air Force Base in October 2011 atop a
Delta IIrocket. This was a multi-payload mission with four other CubeSats,
AubieSat-1,
M-Cubed,
Explorer-1_Prime and
RAX-2.[2]
On board control is provided by a Pumpkin FM430 flight control module containing a
Texas Instruments MPS430
microcontroller. Communications are provided by a
half-duplexUHFmodem with a 1.5 Mbit/s downlink (465 MHz) and 19.2 kbit/s uplink (450 MHz). The satellites carry four Electric Field Probe sensors on telescopic booms, two DC
Langmuir probes for detection of
ions and a three-axis
magnetometer for measuring
magnetic fields.[4]
