On May 21, a Japanese H-IIB rocket roared off the launch pad with the ninth and final H-II Transfer Vehicle (HTV) (Kounotori) resupply ship to the International Space Station (ISS).

But, the launch was not the end of the line for Japanese cargo delivery. The Japan Aerospace Exploration Agency (JAXA) is developing an improved variant known as HTV-X to supply the space station and possibly the lunar Gateway.

Japan Launches Resupply Ship to International Space Station

TOKYO (JAXA PR) — At exactly 31 minutes and 00 seconds past 2 o’clock on the morning of May 21, 2020, the H-II Transfer Vehicle known as “KOUNOTORI9” (HTV9), the cargo transporter to the International Space Station (ISS), was launched aboard H-IIB Launch Vehicle No. 9 (H-IIB F9) from the JAXA Tanegashima Space Center.

The H-IIB F9 flight proceeded nominally. Approximately 15 minutes and 7 seconds after launch, the payload separated from the launch vehicle as planned.

JAXA expresses its sincere appreciation for the support provided by all involved.

Japan continues to make progress toward the first flight of its new H3 launch vehicle with a successful test firing of the booster’s LE-9 first-stage engine on April 30.

JAXA reports that the engine fired for the planned duration of 240 seconds (4 minutes) at the space agency’s Tanegashima Space Center. It was the seventh hot fire of the new engine, which is powered by liquid oxygen and liquid hydrogen.

Japan Launches Supply Ship to Space Station

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.

Launch of Japanese Cargo Ship Rescheduled for Wednesday

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.

Japanese H-IIB Booster Suffers Fire on Launch Pad

The rocket remains intact, but the H-IIB rocket will not launch the HTV cargo ship to the International Space Station today.

This is a developing story. I will update as JAXA releases more information.

Japanese Cargo Ship Set to Launch to ISS

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:

Partnership, Teamwork Enable Landmark Science Glovebox Launch to Space Station

NASA’s new Life Sciences Glovebox undergoes testing at NASA’s Marshall Space Flight Center in Huntsville, Alabama, prior to its Sept. 22 flight to the International Space Station. The research facility is 26 inches high, 35 inches wide and 24 inches deep, with a 15-cubic-foot workspace. It will enable researchers to conduct new experiments studying the effects of microgravity on the human body — aiding deep space exploration missions into the solar system.

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.

JAXA Begins Tests of H-III Engines

The Nikkei Asian Review reports JAXA began test firings of the LE-9 rocket engine, which will power its new H-III launch vehicle. The first round of testing will include 11 firings through June.

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.
