Mitsubishi Heavy Industries, Ltd. (MHI) and Japan Aerospace Exploration Agency (JAXA) have updated launch schedule of the H-IIB Launch Vehicle No. 7(H-IIB F7) which carries aboard the H-II Transfer Vehicle “KOUNOTORI7” (HTV7), the cargo transporter to the International Space Station (ISS).
Necessity arose to investigate the H-IIB F7 propulsion system, forcing MHI and JAXA to cancel the launch previously rescheduled for September 15, 2018. MHI and JAXA have taken the course of action necessary to identify and deal with the cause that the investigation revealed.
The corrective measures which ensued from the investigation have completed. Accordingly, H-IIB F7 launch schedule updates go as follows:
Launch Date: September 22, 2018
Launch Time: Around 3:15 a.m. (Japan Standard Time, JST) *1
Reserved Launch Period: September 23 through October 31, 2018 *2
*1: Launch time is approximate and subject to change, to coordinate with the latest ISS orbit and operations.
*2: Launch time and date during the reserved launch period are pending, to be determined by the ISS operations and other status.
