TANEGASHIMA SPACE CENTER, Japan (MHI PR) — At 1:05:05 a.m., September 25, 2019, Mitsubishi Heavy Industries, Ltd. (MHI) launched the H-IIB Launch Vehicle No. 8 (H-IIB F8) which carries aboard the H-II Transfer Vehicle “KOUNOTORI8” (HTV8), the cargo transporter to the International Space Station (ISS), from the JAXA Tanegashima Space Center.
H-IIB F8 flight proceeded nominally. Approximately 15 minutes 2 seconds after launch, as planned, the payload separated from the launch vehicle.
MHI expresses sincere appreciation for the support by all.
WASHINGTON (NASA PR) — A Japanese cargo spacecraft loaded with more than four tons of supplies, spare parts, and experiment hardware is scheduled to launch from the Tanegashima Space Center in southern Japan to the International Space Station at 12:05 p.m. EDT Tuesday, Sept. 24 (1:05 a.m. Sept. 25 in Japan). Live coverage on NASA Television and the agency’s website will begin at 11:30 a.m.
TOKYO (MHI PR) — Mitsubishi Heavy Industries, Ltd. (MHI) has revised the launch schedule of the H-IIB Launch Vehicle No. 8 (H-IIB F8) which carries aboard the H-II Transfer Vehicle “KOUNOTORI8” (HTV8), the cargo transporter to the International Space Station (ISS) from the JAXA Tanegashima Space Center.
Launch Date: Wednesday, Sept. 25, 2019 at 1:05 am JST (Tuesday, Sept. 24 at 1605 UTC/12:05 pm EDT)*1 Launch Window: Sept. 26 through Oct. 31, 2019
The changes will be made based on the results of the latest orbit based analysis (※ 1) of the International Space Station and Soyuz spacecraft. It was revealed there’s a possibility that the 2nd stage of H-IIB rocket after separation from “KOUNOTORI8” may approach the Soyuz spacecraft.
MHI canceled the launch of the H-IIB F8 on September 11 due to a fire at the movable launch pad exit hole during the countdown operation.
As a result of the investigation, it was confirmed that there was a high possibility that the fire spread due to the static electricity generated by the oxygen dripping from the engine exhaust port during the propellant filling operation, which continued to blow on the heat-resistant material in the exit hole at the movable launch pad.
We have taken corrective measures and have confirmed normal functioning of the rocket and facility.
*1: Collision Avoidance Analysis to prevent collision between the rocket and debris from the rocket and manned space systems (Space Station, etc.) in orbit after launching the rocket. The launch was previously rescheduled for September 24, 2019.
The launch time is subject to change as the ISS orbit is updated.
Launch time and date during this period are pending, determined by the ISS operations and other status.
H-II Transfer Vehicle KOUNOTORI8, the cargo transporter to the International Space Station (ISS), will launch aboard the H-IIB Vehicle No. 8 from JAXA Tanegashima Space Center as follows:
Date: Wednesday, September 11, 2019 Time: 6:33 a.m. JST (2133 GMT /5:33 p.m. EDT Tuesday, September 10) Reserved Launch Period: September 12 through October 31, 2019 Arrival at ISS: Evening of September 14, 2019
HUNTSVILLE, Ala. (NASA PR) — As the Japan Aerospace Exploration Agency‘s H-IIB rocket carries NASA’s Life Sciences Glovebox toward its berth on the International Space Station, hardware specialists at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and their partners around the world are eager to initiate new, high-value biological research in Earth orbit.
The JAXA H-IIB rocket, hauling the state-of-the-art microgravity research facility and other cargo via the H-II Transport Vehicle-7 (HTV-7), successfully lifted off at 1:52 p.m. EDT on Sept. 22 from Tanegashima Space Center in southern Japan.
TANEGASHIMA SPACE CENTER, Japan (JAXA PR) — At 2:52:27 a.m., September 23, 2018, Mitsubishi Heavy Industries, Ltd. (MHI) and Japan Aerospace Exploration Agency (JAXA) launched 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), from the JAXA Tanegashima Space Center.
The new booster is set to replace the H-IIA and H-IIB launchers, which are the mainstay of Japan’s orbital rocket fleet. Mitsubishi Heavy Industries and IHI are leading the development of the new two-stage launch vehicle.
H-III is designed to launch payloads at lower costs. The basic configuration can carry 4 metric tons into sun synchronous orbit. By adding two to four strap-on boosters to the first stage, H-III will be able to lift up to 6.5 metric tons into geostationary transfer orbit.
The new booster will have a base cost of about 5 billion yen ($43.9 million). The H-IIA costs an estimated 10 billion yen ($87.8), with the more powerful H-IIB costing 10 billion yen ($131.5 million).
JAXA’s goal is for the H-III to complete flight tests and enter service in March 2021.
TOKYO (JAXA PR) — Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA) successfully launched the H-IIB Launch Vehicle No. 6 (H-IIB F6) with cargo transporter to the International Space Station, the H-II Transfer Vehicle “KOUNOTORI6” (HTV6) on board at 10:26:47 p.m. on December 9, 2016 (JST) from the Tanegashima Space Center.
The launch vehicle flew as planned, and at approximately 15 minutes and 11 seconds after liftoff, the separation of HTV6 was confirmed.
At the time of the launch,the weather was fine, the wind speed was 4.3 meters/second, from the north-west, and the temperature was 15.5 degrees Celsius.
TOKYO (JAXA PR) — As a result of the successful launch of the H-IIB Launch Vehicle No. 3, the Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries LTD. (MHI) have agreed to privatize the H-IIB launch service today according to the “Basic Agreement on Development and Launch Service of the H-IIB Launch Vehicle.”
With today’s agreement, JAXA will procure launch and transportation services from MHI when a payload is launched by the H-IIB Launch Vehicle. However, JAXA will continue to take responsibility of safety operations including overall safety confirmation, ground safety assurance, and flight safety and flight data acquisition in the same framework as when an H-IIA Launch Vehicle is launched.
Through the privatization, we can expect to secure Japan’s international competitiveness both for the H-IIA and H-IIB by reducing costs, improving quality and energizing activities via efficient and swift management methods of the private sector. Meanwhile, JAXA would like to engage in enhancing reliability as well as maintaining and operating Japan’s launch facilities for Japan’s flagship launch vehicle series in order to provide reliable launch means to broader demands.

On December 16, JAXA and Mitsubishi Heavy Industries Ltd. conducted a cryogenic test of the H-IIB Launch Vehicle No. 2 (H-IIB F2) at the Tanegashima Space Center. The launch vehicle and the ground system were connected for the test and all the launch operation procedures just prior to ignition were simulated in the same manner as on the launch day. As a result, no problem was found in functions and data of the launch vehicle and the ground system. We will thus move forward to be ready for launch.
The launch of the H-IIB Launch Vehicle No. 2 (H-IIB F2) with the H-II Transfer Vehicle 2 (HTV2, a cargo transporter to the International Space Station) onboard was reported to the Space Activities Commission (SAC) is as follows.
