AOBA VELOX-IV was launched on Friday, January 18 at around 8.50 am from the Japan Aerospace Exploration Agency Epsilon-4 rocket.​

AOBA VELOX-IV (AV4) is​ a low-cost 2U CubeSat which is developed in collaboration between Nanyang Technological University, Singapore ​and Kyushu Institute of Technology, Japan. The main objective of this mission is technological demonstration of taking earth glow images in LEO by using low-light camera and pulsed plasma thruster (PPT) towards observation of the lunar horizon glow in future moon mission.​
