DIDO-2 (aka Chen Jiayong 1, COSPAR 2017-008BE) is a nano-satellite of the Israeli/Swiss company . The nano-satellite is part of a research project whose goal is to test a miniaturized end-to-end pharmaceutical laboratory (called mGnify lab) in space under microgravity conditions. The project includes two satellites called DIDO-1 and DIDO-2. The platforms of the 3U CubeSats are developed and built by the Dutch company ISIS. The first satellite DIDO-1 was originally to fly on a Falcon 9 in 2016. The current (as of 2019) status and plans for this satellite are unknown.
