    Sakigake ('Pioneer') was a test spacecraft similar to Suisei (Planet-A). Objectives were :verification of fundamental technology related to interplanetary missions, including deep-space communication, attitude control, attitude determination; study and observation of solar wind and plasma waves and interplanetary magnetic field. It carried three instruments to measure plasma wave spectra, solar wind ions, and interplanetary magnetic fields. The spacecraft was spin-stabilized at two different rates (5 and 0.2 rpm). It was equipped with hydrazine thrusters for attitude and velocity control, star and sun sensors for attitude determination, and a mechanically despun off-set parabolic dish for long-range communication. Launched into an initial heliocentric orbit with a period of 318.8 days, at 151.4 x 121.9 million km (0.815 x 1.012 AU), 1.439 degree inclination. Flew by Comet Halley on its sunward side at a distance of about 7 million kilometers on March 11, 1986. It later made an Earth swingby on January 8, 1992 with a closest approach of 88,997 km. This was the first planet-swingby for a Japanese spacecraft. During the approach, Sakigake observed the geotail, with passage occurring at 290 Re on 14 June 1993 before ISTP's multi-spacecraft investigation of that region. The second Earth swingby was on June 14, 1993 at 40 Re, and the third on October 28, 1994 at 86 Re. Almost no hydrazine remained so no further maneuvers were accomplished. Telemetry contact was lost on 15 November 1995 at a distance of 106 million km. Future mission planning had included a 23.6 km/s, 10,000 km flyby of Comet Honda-Mrkos-Pajdusakova on Feb 3, 1996 (approaching the nucleus along the tail) some 0.17 AU from the Sun, and a 14 million km passage of Comet Giacobini-Zinner on Nov 29, 1998.

    At first thought not to have reached orbit. Later the re-entry vehicle was discovered in Ghana having reentered and deployed its parachute on January 15. At T+103 sec, during the second stage burn, the vehicle veered off course. The payload service module entered a 110 x 250 km x 33 degree orbit, instead of the intended 270 x 380 km and re-entered on its second orbit. The re-entry capsule was found later in Ghana. A failure of the second stage attitude control system was blamed, although it was considered likely that the payload was too heavy for the vehicle, being twice the mass of earlier MU-3S payloads.

  • Nozomi - . Mass: 258 kg (568 lb). Nation: Japan. Agency: ISAS. Manufacturer: NEC. Class: Mars. Type: Mars probe. Spacecraft Bus: Nozomi. Spacecraft: Nozomi. USAF Sat Cat: 25383 . COSPAR: 1998-041A. Apogee: 489,381 km (304,086 mi). Perigee: 703 km (436 mi). Inclination: 27.3000 deg. Period: 20,910.00 min.

    Originally known as Planet-B; renamed Nozomi ('Hope') after launch. The third stage and payload entered a 146 x 417 km x 31.1 deg parking orbit. The KM-V1 kick (fourth) stage then fired to place the spacecraft into a circumlunar 359 x 401491 km x 28.6 deg orbit. Nozomi made multiple lunar and Earth gravity assist passes to increase its energy for solar orbit insertion and the cruise to Mars.. The spacecraft used a lunar swingby on 24 September and another on 18 December 1998 to increase the apogee of its orbit. It swung by Earth on 20 December at a perigee of about 1000 km. The gravitational assist from the swingby coupled with a 7 minute burn of the bipropellant engine put Nozomi into an escape trajectory towards Mars. It was scheduled to arrive at Mars on 11 October 1999 at 7:45:14 GMT, but the Earth swingby left the spacecraft with insufficient acceleration and two course correction burns on 21 December used more propellant than planned, leaving the spacecraft short of fuel. The new plan is for Nozomi to remain in heliocentric orbit for an additional four years and encounter Mars at a slower relative velocity in December 2003.

It carried a Thiokol Star 30 solid apogee motor and a set of station-keeping thrusters with 200 kg of propellant. A propulsion problem in the final stage of rocket stranded the satellite at a much lower altitude than planned. Since BSAT 2B carried only a soild propellant apogee kick motor, it was unable to maneuver itself to a useful orbit.

    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 Bus: DASH 2002. Spacecraft: DASH 2002. USAF Sat Cat: 27368 . COSPAR: 2002-003B. Apogee: 35,778 km (22,231 mi). Perigee: 357 km (221 mi). Inclination: 28.3000 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.

    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.
