Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA
120-624: A hard X-ray detector (HXD). However, the XRS was rendered inoperable due to a malfunction which caused the satellite to lose its supply of liquid helium. The next JAXA x-ray mission is the Monitor of All-sky X-ray Image (MAXI) . MAXI continuously monitors astronomical X-ray objects over a broad energy band (0.5 to 30 keV). MAXI is installed on the Japanese external module of the ISS. On 17 February 2016, Hitomi (ASTRO-H)
180-496: A future mission. On 14 September 2007, JAXA succeeded in launching the lunar orbit explorer Kaguya , also known as SELENE, on an H-2A rocket (costing 55 billion yen including launch vehicle), the largest such mission since the Apollo program . Its mission was to gather data on the Moon's origin and evolution . It entered lunar orbit on 4 October 2007. After 1 year and 8 months, it impacted
240-558: A long fairing, whereas an H3-30S has three engines, no solid rocket boosters, and a short fairing. W-type fairing is similar to L-type except wider 5.4 m diameter. W-type was mentioned in the description of JAXA's web page, but not in the current description as of November 2023 . Manufacturing of W-type fairing is contracted to RUAG Space (now Beyond Gravity ), whereas other types are manufactured by Kawasaki Heavy Industries. As of November 2018 , three configurations are planned: H3-30, H3-22, and H3-24. A previously mentioned variant,

The rocket, known as the SS-520-5, is the world's smallest orbital launcher. In 2023, JAXA began operating the H3 , which will replace the H-IIA and H-IIIB; the H3 is a liquid-fueled launch vehicle developed from a completely new design like
360-418: A payload capacity of 28,300 kg (62,400 lb) to low Earth orbit . H3 will have a "dual-launch capability, but MHI is focused more on dedicated launches" in order to prioritize schedule assurance for customers. As of 2018, MHI is aiming to price the H3 launch service on par with SpaceX's Falcon 9. Sources: Japanese Cabinet The first launch attempt on 17 February 2023 was aborted just before
420-475: A phenomenon in which the cloud top winds in the troposphere circulates around the planet faster than the speed that Venus itself rotates. A thorough explanation for this phenomenon has yet been found. JAXA/ISAS was part of the international Laplace Jupiter mission proposal from its foundation. A Japanese contribution was sought in the form of an independent orbiter to research Jupiter's magnetosphere, JMO (Jupiter Magnetospheric Orbiter). Although JMO never left
480-428: A planned dogleg maneuver in order to achieve sun-synchronous orbit and not in fact a loss of control. Approximately five minutes and twenty-seven seconds after launch, the second stage engine failed to ignite. After continuing to be unable to confirm second stage engine ignition, and with the velocity of the rocket continuing to fall, JAXA sent a self-destruct command to the rocket at around L+ 00:14:50 because there
540-466: Is not pointed towards Earth. The mission was considered fully successful after confirmation that its primary goal, landing within 100 m (330 ft) of the target was achieved, despite subsequent issues. On 29 January, the lander resumed operations after being shutdown for a week. JAXA said it re-established contact with the lander and its solar cells were working again after a shift in lighting conditions allowed it to catch sunlight. After that, SLIM
600-502: Is planned to have a temperature of just 4.5 K and will be much colder. Unlike Akari, which had a geocentric orbit , SPICA will be located at Sun–Earth L 2 . The launch is expected in 2027 or 2028 on JAXA's new H3 Launch Vehicle , however the mission is not yet fully funded. ESA and NASA may also each contribute an instrument. The SPICA mission was cancelled in 2020. Starting from 1979 with Hakucho (CORSA-b), for nearly two decades Japan had achieved continuous observation. However, in

780-504: Is reviewing a new spacecraft mission to the Martian system; a sample return mission to Phobos called MMX (Martian Moons Explorer). First revealed on 9 June 2015, MMX's primary goal is to determine the origin of the Martian moons . Alongside collecting samples from Phobos, MMX will perform remote sensing of Deimos , and may also observe the atmosphere of Mars as well. As of December 2023, MMX
840-514: Is the first all sky survey since the first infrared mission IRAS in 1983. (A 3.6 kg nanosatellite named CUTE-1.7 was also released from the same launch vehicle.) JAXA is also doing further R&D for increasing the performance of its mechanical coolers for its future infrared mission, SPICA . This would enable a warm launch without liquid helium. SPICA has the same size as the ESA Herschel Space Observatory mission, but
900-534: Is the most important factor in achieving cost reduction, improved safety and increased thrust. The expander bleed cycle used in the LE-9 engine is a highly reliable combustion method that Japan has put into practical use for the LE-5A / B engine. However, it is physically difficult for an expander bleed cycle engine to generate large thrust, so the development of the LE-9 engine with a thrust of 1,471 kN (331,000 lb f )
960-455: Is to be launched in fiscal year 2026. On 9 August 2004, ISAS successfully deployed two prototype solar sails from a sounding rocket. A clover-type sail was deployed at 122 km altitude and a fan type sail was deployed at 169 km altitude. Both sails used 7.5 micrometer -thick film. ISAS tested a solar sail again as a sub-payload to the Akari (ASTRO-F) mission on 22 February 2006. However
1020-565: Is to have a solar sail mission to Jupiter after 2020. The first Japanese astronomy mission was the X-ray satellite Hakucho (CORSA-b), which was launched in 1979. Later ISAS moved into solar observation, radio astronomy through space VLBI and infrared astronomy. Active Missions: SOLAR-B , MAXI , SPRINT-A , CALET , XRISM Under Development: Retired: HALCA , ASTRO-F , ASTRO-EII , and ASTRO-H Cancelled(C)/Failed(F): ASTRO-E (F), ASTRO-G (C), Japan's infrared astronomy began with
1080-726: The H-II Transfer Vehicle six times. This cargo spacecraft was responsible for resupplying the Kibo Japanese Experiment Module on the International Space Station . To be able to launch smaller mission on JAXA developed a new solid-fueled rocket, the Epsilon as a replacement to the retired M-V . The maiden flight successfully happened in 2013. So far, the rocket has flown six times with one launch failure. In January 2017, JAXA attempted and failed to put
1140-608: The H-IIA (H "two" A) rocket from the former NASDA body as a medium-lift launch vehicle . JAXA has also developed a new medium-lift vehicle H3 . For smaller launch needs, JAXA uses the Epsilon rocket. For experiments in the upper atmosphere JAXA uses the SS-520 , S-520 , and S-310 sounding rockets . Historical, nowadays retired, JAXA orbital rockets are as follows: Mu rocket family ( M-V ) and H-IIB . Japan launched its first satellite, Ohsumi , in 1970, using ISAS' L-4S rocket. Prior to

1560-581: The H-II, rather than an improved development like the H-IIA and H-IIB, which were based on the H-II. The design goal of the H3 is to increase launch capability at a lower cost than the H-IIA and H-IIB. To achieve this, an expander bleed cycle was used for the first time in the world for the first stage of the engine. Japan's first missions beyond Earth orbit were the 1985 Halley's comet observation spacecraft Sakigake (MS-T5) and Suisei (PLANET-A). To prepare for future missions, ISAS tested Earth swing by orbits with
1620-451: The H3 was authorized by the Japanese government on 17 May 2013. The H3 Launch Vehicle is being jointly developed by JAXA and Mitsubishi Heavy Industries (MHI) to launch a wide variety of commercial satellites. The H3 was designed with cheaper engines compared to the H-IIA , so that manufacturing the new launch vehicle would be faster, less risky, and more cost-effective. JAXA and Mitsubishi Heavy Industries were in charge of preliminary design,
1680-510: The H3-32, was cancelled in late 2018 when the performance of the H3-22 variant, sporting one less engine on the core booster, was found to be greater than anticipated, putting it close to the H3-32's performance. While the H3-32 would have provided greater performance, JAXA cited SpaceX 's experience with their Falcon 9 rocket, which routinely lifted commercial communications satellite payloads to less than

ISAS had been most successful in its space program in the field of X-ray astronomy during the 1980s and 1990s. Another successful area for Japan has been Very Long Baseline Interferometry (VLBI) with the HALCA mission. Additional success was achieved with solar observation and research of
2640-483: The mission lasted until 2003 and the satellite was retired at the end of 2005. In FY 2006, Japan funded the ASTRO-G as the succeeding mission. ASTRO-G was canceled in 2011. One of the primary duties of the former NASDA body was the testing of new space technologies, mostly in the field of communication. The first test satellite was ETS-I, launched in 1975. However, during the 1990s, NASDA was afflicted by problems surrounding
2700-567: The mission was to collect samples from a small near-Earth asteroid named 25143 Itokawa . The craft rendezvoused with the asteroid in September 2005. It was confirmed that the spacecraft successfully landed on the asteroid in November 2005, after some initial confusion regarding the incoming data. Hayabusa returned to Earth with samples from the asteroid on 13 June 2010. Hayabusa was the world's first spacecraft to return asteroid samples to Earth and

SLIM was expected to operate only for one lunar daylight period, which lasts for 14 Earth days, and the on-board electronics were not designed to withstand the nighttime temperatures on the Moon. On 25 February 2024, JAXA sent wake-up calls and found SLIM had successfully survived
3600-722: Was the most challenging and important development element. Firing tests of the LE-9 first-stage engine began in April 2017, with the first tests of the solid rocket boosters occurring in August 2018. On 21 January 2022, the launch of the first H3 was rescheduled to FY 2022 or later, citing technical problems regarding the first stage LE-9 engine. The H3 Launch Vehicle is a two-stage launch vehicle. The first stage uses liquid oxygen and liquid hydrogen as propellants and carries zero, two or four strap-on solid rocket boosters (SRBs) (derived from SRB-A ) using polybutadiene fuel.
