On Sept. 10, 2009, the Japan Aerospace Exploration Agency (JAXA) launched its first cargo delivery spacecraft, the H-II Transfer Vehicle-1 (HTV-1), to the International Space Station. The HTV cargo vehicles, also called Kounotori, meaning white stork in Japanese, not only maintained the Japanese Experiment Module Kibo but also resupplied the space station in general with pressurized and unpressurized cargo and payloads. Following its rendezvous with the space station, Expedition 20 astronauts grappled and berthed HTV-1 on Sept. 17, and spent the next month transferring its 9,900 pounds of internal and external cargo to the space station and filling the HTV-1 with trash and unneeded equipment. They released the craft on Oct. 30 and ground controllers commanded it to a destructive reentry on Nov. 1.

The HTV formed part of a fleet of cargo vehicles that at the time included NASA’s space shuttle until its retirement in 2011, Roscosmos’ Progress, and the European Space Agency’s (ESA) Automated Transfer Vehicle that flew five missions between 2008 and 2015. The SpaceX Cargo Dragon and Orbital (later Northrup Grumman) Cygnus commercial cargo vehicles supplemented the fleet starting in 2012 and 2013, respectively. The HTV weighed 23,000 pounds empty and could carry up to 13,000 pounds of cargo, although on this first flight carried only 9,900 pounds. The vehicle included both a pressurized and an unpressurized logistics carrier. Following its rendezvous with the space station, it approached to within 33 feet, at which point astronauts grappled it with the station’s robotic arm and berthed it to the Harmony Node 2 module’s Earth facing port. Space station managers added two flights to the originally planned seven, with the last HTV flying in 2020. An upgraded HTV-X vehicle will soon make its debut to carry cargo to the space station, incorporating the lessons learned from the nine-mission HTV program.

Prelaunch processing of HTV-1 took place at the Tanegashima Space Center, where engineers inspected and assembled the spacecraft’s components. Workers installed the internal cargo into the pressurized logistics carrier and external payloads onto the External Pallet that they installed into the unpressurized logistics carrier. HTV-1 carried two external payloads, the Japanese Superconducting submillimeter-wave Limb Emission Sounder (SMILES) and the U.S. Hyperspectral Imager for Coastal Ocean (HICO)-Remote Atmospheric and Ionospheric detection System (RAIDS) Experiment Payload (HREP). On Aug. 23, 2009, workers encapsulated the assembled HTV into its payload shroud and a week later moved it into the Vehicle Assembly Building (VAB), where they mounted it atop the H-IIB rocket. Rollout from the VAB to the pad took place on the day of launch.

On Sept. 10 – Sept. 11 Japan time – HTV-1 lifted off its pad at Tanegashima on the maiden flight of the H-IIB rocket. Controllers in Tanegashima’s launch control center monitored the flight until HTV-1 separated from the booster’s second stage. At that point, HTV-1 automatically activated its systems and established communications with NASA’s Tracking and Data Relay Satellite System. Control of the flight shifted to the mission control room at the Tsukuba Space Center outside Tokyo. Controllers in the Mission Control Center at NASA’s Johnson Space Center in Houston also monitored the mission’s progress.

Following several days of systems checks, HTV-1 approached the space station on Sept. 17. Members of Expedition 20 monitored its approach, as it stopped within 33 feet of the orbiting laboratory. Using the space station’s Canadarm2 robotic arm, Expedition 20 Flight Engineer and NASA astronaut Nicole P. Stott grappled HTV-1. Fellow crew member Canadian Space Agency astronaut Robert Thirsk berthed the vehicle on the Harmony Node 2 module’s Earth-facing port. The following day, the Expedition 20 crew opened the hatch to HTV-1 to begin the cargo transfers.

Over the next several weeks, the Expedition 20 and 21 crews transferred more than 7,900 pounds of cargo from the pressurized logistics carrier to the space station. The items included food, science experiments, robotic arm and other hardware for the Kibo module, crew supplies including clothing, toiletries, and personal items, fluorescent lights, and other supplies. They then loaded the module with trash and unneeded equipment, altogether weighing 3,580 pounds.

Working as a team, NASA astronauts Stott and Michael R. Barratt along with Thirsk and ESA astronaut Frank DeWinne performed the transfer of the external payloads. On Sept. 23, using the station’s robotic arm, they grappled the Exposed Pallet (EP) and removed it from HTV-1’s unpressurized logistics carrier, handing it off to the Japanese remote manipulator system arm that temporarily stowed it on the JEM’s Exposed Facility (JEM-EF). The next day, using the Japanese arm, DeWinne and Stott transferred the SMILES and HREP experiments to their designated locations on the JEM-EF. On Sept. 25, they grappled the now empty EP and placed it back into HTV-1’s unpressurized logistics carrier.

Following completion of all the transfers, Expedition 21 astronauts aboard the space station closed the hatch to HTV-1 on Oct. 29. The next day, Stott and DeWinne grappled the vehicle and unberthed it from Node 2. While passing over the Pacific Ocean, they released HTV-1 and it began its departure maneuvers from the station. On Nov. 1, the flight control team in Tsukuba sent commands to HTV-1 to execute three deorbit burns. The vehicle reentered the Earth’s atmosphere, burning up off the coast of New Zealand, having completed the highly successful 52-day first HTV resupply mission. Eight more HTV missions followed, all successful, with HTV-9 completing its mission in August 2020.
