The Vegetation instrument was originally flown on France's van-sized SPOT-4 and SPOT-5 satellites, then a smaller version was flown on the cubic-metre scale Proba-V satellite in 2013, made up of three Vegetation imagers overall. Now a remaining Vegetation imager is being flown aboard the Proba-V Companion CubeSat. This nanosatellite is just 20 cm x 20 cm x 30 cm in size.
