  Launch postponed from february, July 22 and August 25. First launch of the H-2A launch vehicle. A failure after all of the problems with the earlier H-2 version would probably have resulted in cancellation of the program. The Laser Ranging Experiment satellite carried 126 laser retro reflectors and separated from the second stage at 0739 GMT into its operational 'Molniya' type orbit. The eventual goal of H-2A was to launch geosynchronous spacecraft at costs comparable to those of other countries. The LRE remained in a simulated geosynchronous transfer orbit; laser reflections from it would be used to precisely ascertain the orbital injection accuracy of the H-2A.

  Technology qualification flight - maiden flight of H-2A booster. Launch delayed from January 31 and February 3. The second stage began its first burn at 0251 UTC and at 0257 UTC entered a 500 km circular parking orbit. After a 12 minute coast the second burn put stage 2 in geostationary transfer orbit. At 0315 UTC the small DASH vehicle was meant to separate from the upper adapter, but this apparently did not occur. At 0325 UTC VEP-3/upper adapter/DASH combination separated from the second stage, followed by two semi-cylindrical side panels, revealing the previously enclosed MDS-1 technology satellite which was ejected at 0331 UTC. At 0425 UTC the second stage was scheduled to make a third burn to test engine restart, completing the H-2A-2F mission.

• DASH - . Mass: 70 kg (154 lb). Nation: Japan. Agency: NASDA. Class: Technology. Type: Navigation technology satellite. Spacecraft: DASH 2002. USAF Sat Cat: 27368 . COSPAR: 2002-003B. Apogee: 35,778 km (22,231 mi). Perigee: 357 km (221 mi). Inclination: 28.30 deg. Period: 634.00 min.

  The VEP-3 launch instrumentation package mounted on top of the DASH had a mass of 33 kg. The side adapter panels were halves of a 4.1m long 4.0m diameter cylinder. DASH (Demonstrator of Atmospheric Reentry System and Hypervelocity) was to test the reentry system for the MUSES-C asteroid probe. The plan was to fire the deorbit motor three days after launch, then separate the reentry capsule which would enter the Earth's atmosphere at 10 km/s and land in the Hodh el Gharbi region of Mauritania at about 8.5W 17.2N. Typical satellite reentries are at only 7.5 km/s, while hyperbolic (escape) velocity at the top of the atmosphere is over 11 km/s, so DASH would have been travelling much faster than typical reentry vehicles, but not quite at escape velocity.

  The spacecraft was intended to rendezvous with asteroid 1999 JU3, survey it from orbit, touch down briefly to sample the surface, and return samples to Earth. Launched into a 0.915 AU x 1.089 AU x 6.8 deg solar orbit. Five small, beanbag-like 'target markers' could be ejected onto the surface in advance to help guide the vehicle. Hayabusa-2 also carried three 1 kg class lander/hopper devices, Minerva II-1a, II-1b and II-2, which were to be ejected onto the surface, together with a 10 kg German-built lander called MASCOT. Hayabusa-2 was also to eject a 'Self-Contained Impactor' (SCI) device onto the surface. As the parent spacecraft moved off to the side it would further eject the DCAM-3 camera subsatellite, which would monitor detonation of SCI's high explosive, intended to ram the SCI's body into the asteroid and generate an artificial crater.

  HTV-5 arrived at the ISS on 24 August and was berthed at the Harmony nadir port at 14:02 GMT. HTV-5's External Platform carries the CALET electron/cosmic-ray detector which was installed on the Kibo Exposed Facility. The pressurized compartment carried nine racks: the US Galley Rack, to be installed in the Unity node; the JAXA Multipurpose Small Payload Rack 2 (MSPR-2), installed in Kibo at JPM1F2; and seven HTV Resupply Racks. One of these used the new HRR-D storage system to increase the HTV capacity. Contained in the HRRs were a SAFER EVA backpack, a Mouse Habitat Unit (but no mice for it), 18 cubesats, the Nanoracks External Platform (NREP) and JAXA ExHAM-2 expsoure unit. The latter two were used for mounting external experiments. The cubesats were: PlanetLabs Flock 2b-1 to 2b-14, for Earth imaging; GOMSpace GOMX-3, for tests of ADS-B aircraft data relay; Aalborg University AAUSAT-5, a 1U sat for tests of AIS ship tracking receivers; Brazilian Space Agency/University of Brasilia SERPENS with technology communications payloads; Chiba Inst. Of Technology S-CUBE with UV and visible imagers to observe meteors from above. All the cubesats are 3U form factor except for AAUSAT-5. CALET had a mass of 650 kg; the 7 HRR racks carried 6057 kg of cargo. HTV-5 carried 2306 kg of propellant. The Galley and MSPR racks probably had a mass around 500 kg each; the dry HTV without payloads was about 6100 kg. On 25 August the SSRMS robot arm extracted the HTV Exposed Pallet and handed it to the JEM RMS, which berthed the EP on the Exposed Facility at location EFU10. The JEM RMS then grappled the CALET experiment and moved it to EFU9. The SSRMS arm unberthed the HTV-5 from the Harmony module at 11:12 GMT on 28 September. Release was delayed one orbit due to a robotics problem and occurred at 16:53 GMT. The next day HTV-5 lowered its orbit with two burns and then made a final deorbit burn at 20:08 GMT, with atmosphere entry around 20:33 GMT for destruction over the South Pacific.

• Telstar 12V - . Nation: Japan. Class: Communications. Type: Communications satellite. Spacecraft: Eurostar 3000. USAF Sat Cat: 41036 . COSPAR: 2015-068A. Apogee: 35,637 km (22,143 mi). Perigee: 3,140 km (1,950 mi). Inclination: 19.20 deg.

  Telesat of Canada's Telstar 12 Vantage comms satellite launched to geotransfer orbit in the first commercial launch of Japan's H-IIA rocket and the first use of an uprated LOX/LH2 upper stage modified for a long coast to a third burn at geotransfer apogee.

• Hitomi - . Payload: ASTRO-H. Nation: Japan. Class: Astronomy. Type: X-ray astronomy satellite. USAF Sat Cat: 41337 . COSPAR: 2016-012A. Apogee: 580 km (360 mi). Perigee: 565 km (351 mi). Inclination: 31.00 deg.

  ASTRO-H X-ray astronomy observatory rode H2A No. 30 to a low Earth orbit. It carried an array of five X-ray telescopes. Hitomi suffered a major anomaly on Mar 25 while observing the quasar Markarian 205. At 1910 UTC the satellite started tumbling and then at 0140 UTC Mar 26 the spacecraft partly disintegrated. US tracking found eleven debris objects in orbit. During the next scheduled pass at 0740 UTC, JAXA received only a short burst from the radio beacon and nothing more; three more such beacon detections were obtained up to Mar 28, when the spacecraft fell silent. Ground-based optical observations showed that at least two of the debris objects, 2016-012A and 012L, were bright and tumbling several times a minute. 2016-012A was probably the main spacecraft bus. It's possible that 2016-012L was the extensible optical bench with the HXI cameras, or part of the solar panels.

  16-tonne Japanese HTV-6 (Kounotori-6) cargo ship. The pressurized module contains 600 kg of water and 2152 kg of dry cargo. This included two JAXA J-SSOD and one Nanoracks NRCSD-10 cubesat deployers; these were to be transferred to the Kibo module. The HTV also has an Exposed Pallet, which on this mission (using the enhanced capacity EP6B+) carried a set of replacement batteries for the ISS truss, with a total cargo mass of 1367 kg. The S4, S6, P4 and P6 truss segments each contain an Integrated Electronics Assembly (IEA), with 12 Ni-H2 batteries apiece in separate ORUs (Orbital Replacement Units). On this mission the S4 batteries are to be replaced. Six new 197 kg Li-ion battery ORUs were to be installed and six of the 166 kg Ni-H2 battery ORUs were to be transferred to the HTV EP for disposal on reentry. The remaining six Ni-H2 ORUs remained on S4, but they were taken off line and new 29 kg Adapter Plate ORUs were to be installed between them and the truss. On Dec 14 the Exposed Pallet was grappled by the Canadarm-2, pulled out of HTV-6 and attached to the Mobile Base System on the ISS truss. On Dec 15-16 the J-SSOD #5 was moved to the Kibo module's airlock. On Dec 19 the Japanese RMS arm took the MPEP platform, with J-SSOD attached, out of the airlock and the STARS-C cubesat was ejected from it at 0855 UTC. On Dec 27 J-SSOD #6 was installed in the airlock with its sats to be deployed in January. Japan's HTV 6 cargo ship separated from ISS on Jan 27 at 1546 UTC. However, its KITE tether experiment failed to deploy when commanded to do so on Jan 28. HTV 6 was deorbited on Feb 5 at 1442 UTC and entered the atmosphere over the South Pacific at 1506 UTC.

• Arase - . Payload: ARASE (ERG). Nation: Japan. Class: Science. Type: Science satellite. USAF Sat Cat: 41896 . COSPAR: 2016-080A. Apogee: 32,259 km (20,044 mi). Perigee: 228 km (141 mi). Inclination: 31.40 deg.

  Second Epsilon rocket launched the 350 kg ERG geospace science satellite into elliptical orbit. ERG carried experiments to study energetic particles, waves and fields in the magnetosphere. After launch, ERG was renamed 'Arase' (rough water, a metaphor for the dynamic magnetic storms of geospace). The second Epsilon uses a new second stage, the M-35. The first flight in 2013 used a derivative of the M-34 from the old M-V rocket. The M-35, with a mass of 17200 kg, was a growth version sized to match the 2.6m diameter of the larger Epsilon first stage. The third stage was the KM-V2c, with minor improvements compared to the previous mission's KM-V2b. The PBS liquid post-boost 4th stage was not included on this flight.

• TRICOM-1 - . Nation: Japan. Class: Technology. Type: Technology satellite. Spacecraft: Cubesat. COSPAR: 2017-0F01. Apogee: 200 km (120 mi). Perigee: -6,340 km (-6,340 mi). Inclination: 30.00 deg.

  See TRICOM 1. Japan attempted to launch a single cubesat into orbit with a launch vehicle massing less than 3 tonnes. The SS-520 sounding rocket was furnished with a 78 kg third stage which was intended to orbit a 3U, 3 kg cubesat, TRICOM-1. The mission was flight SS-520-4 (SS-520-1 and 2 were normal sounding rocket flights; 3 has not yet flown.) However, telemetry was lost 20 seconds into flight, during first stage burn. Following range safety rules, the command to ignite stage 2 was not sent and the vehicle flew a suborbital path to about 200 km altitude and then splashed down in the ocean. The record smallest successful orbital launch vehicle remains the 9.4-tonne Lambda 4S, also Japanese, which was retired in 1979.
