Mission details:

• On Oct 29, 2018 JAXA launched H-IIA flight F40 from Tanegashima. The main payload was GOSAT-2, the second Greenhouse Gases Observating Satellite, also called Ibuki-2. The 1750 kg satellite - built by Mitsubishi Electric (MELCO) - carries the FTS-2 Fourier transform spectrometer and the CAI-2 Cloud and Aerosol Imager instruments which observe from the ultraviolet out to 16 microns in the infrared.
• The H2A second stage made a single burn to a 590 x 595 km orbit and deployed Ibuki-2, then ejected the Ibuki-2 payload adapter and the two-piece lower fairing.
  This exposed the lower payload deck, whose satellites were deployed into the same orbit.
• After deployment of the satellites, the H-2A second stage made a final depletion burn which changed its inclination from 97.8 deg to 98.9 deg.
• PROITERES 2, from the Osaka Institute of Technology, a 45 kg ion propulsion test satellite, was not part of the launch although it was initially expected to be and was included in the prelaunch press kit.
