In the beginning, NASDA used licensed American models. [62] => [63] => The first model of liquid-fueled launch vehicle developed domestically in Japan was the [[H-II]], introduced in 1994. NASDA developed the H-II with two goals in mind: to be able to launch satellites using only its own technology, such as the ISAS, and to dramatically improve its launch capability over previous licensed models. To achieve these two goals, a [[staged combustion cycle]] was adopted for the first stage engine, the [[LE-7]]. The combination of the [[liquid hydrogen]] two-stage combustion cycle first stage engine and [[solid rocket booster]]s was carried over to its successor, the H-IIA and H-IIB and became the basic configuration of Japan's liquid fuel launch vehicles for 30 years, from 1994 to 2024.{{Cite news [64] => |url=https://www.jstage.jst.go.jp/article/jhts/33/5/33_229/_pdf/-char/ja [65] => |title=History and Prospect of Liquid Rocket Engine Development in Japan [66] => |date=|accessdate=21 February 2024|publisher=J Stage [67] => |archiveurl =https://web.archive.org/web/20211229131449/https://www.jstage.jst.go.jp/article/jhts/33/5/33_229/_pdf/-char/ja|archivedate = 29 December 2021}} [68] => [69] => In 2003, JAXA was formed by merging Japan's three space agencies to streamline Japan's space program, and JAXA took over operations of the [[H-IIA]] liquid-fueled launch vehicle, the [[M-V]] solid-fuel launch vehicle, and several observation rockets from each agency.

The [[Mars]] explorer [[Nozomi (spacecraft)|Nozomi]] (PLANET-B), which ISAS launched prior to the merger of the three aerospace institutes, became one of the earliest difficulties the newly formed JAXA faced. Nozomi ultimately passed 1,000 km from the surface of Mars. On 20 May 2010, the [[Venus]] Climate Orbiter ''[[Akatsuki (spacecraft)|Akatsuki]]'' (PLANET-C) and [[IKAROS]] solar sail demonstrator was launched by a [[H-2A]] launch vehicle. [133] => [134] => On 7 December 2010, Akatsuki was unable to complete its Venus orbit insertion maneuver. Akatsuki finally entered Venus orbit on 7 December 2015, making it the first Japanese spacecraft to orbit another planet, sixteen years after the originally planned orbital insertion of Nozomi. One of Akatsuki's main goal is to uncover the mechanism behind Venus atmosphere's [[Atmosphere of Venus#Circulation|super-rotation]], 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. [135] => [136] => JAXA/ISAS was part of the international [[Europa Jupiter System Mission – Laplace|Laplace]] [[Jupiter]] mission proposal from its foundation. A Japanese contribution was sought in the form of an independent orbiter to research Jupiter's magnetosphere, [[Jupiter Magnetospheric Orbiter|JMO]] (Jupiter Magnetospheric Orbiter). Although JMO never left the conception phase, ISAS scientists will see their instruments reaching Jupiter on the ESA-led [[Jupiter Icy Moon Explorer|JUICE]] (Jupiter Icy Moon Explorer) mission. JUICE is a reformulation of the ESA [[Ganymede (moon)|Ganymede]] orbiter from the Laplace project. JAXA's contribution includes providing components of the RPWI (Radio & Plasma Wave Investigation), PEP (Particle Environment Package), GALA (GAnymede Laser Altimeter) instruments.

This would enable a warm launch without liquid helium. SPICA has the same size as the ESA [[Herschel Space Observatory]] mission, but 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 {{L2|nolink=no}}.

However, in the year 2000 the launch of ISAS's X-ray observation satellite, [[ASTRO-E]] failed (as it failed at launch it never received a proper name). [174] => [175] => Then on 10 July 2005, JAXA was finally able to launch a new [[X-ray astronomy]] mission named [[Suzaku (satellite)|Suzaku]] (ASTRO-EII). This launch was important for JAXA, because in the five years since the launch failure of the original ASTRO-E satellite, Japan was without an [[x-ray telescope]]. Three instruments were included in this satellite: an [[X-ray spectrometer]] (XRS), an [[X-ray imaging spectrometer]] (XIS), and 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. [176] => [177] => The next JAXA x-ray mission is the [[MAXI (ISS Experiment)|Monitor of All-sky X-ray Image (MAXI)]].

However no details are worked out yet other than it will not be launched with the former ISAS's Mu rockets. Instead a H-2A from Tanegashima could launch it. As H-2A is more powerful, SOLAR-C could either be heavier or be stationed at {{L1}} ([[Lagrange point]] 1). [181] => [182] => === Radio astronomy === [183] => In 1998, Japan launched the [[HALCA]] (MUSES-B) mission, the world's first spacecraft dedicated to conduct space VLBI observations of pulsars, among others. To do so, ISAS set up a ground network around the world through international cooperation. The observation part of the mission lasted until 2003 and the satellite was retired at the end of 2005.

[204] => [205] => === OICETS and INDEX === [206] => On 24 August 2005, JAXA launched the experimental satellites [[OICETS]] and [[Reimei|INDEX]] on a Ukrainian [[Dnepr (rocket)|Dnepr rocket]]. OICETS (Kirari) is a mission tasked with testing optical links with the [[European Space Agency]] (ESA) [[ARTEMIS]] satellite, which is around 40,000 km away from OICETS. The experiment was successful on 9 December, when the link could be established. In March 2006, JAXA could establish with OICETS the worldwide first optical links between a LEO satellite and a ground station first in Japan and in June 2006 with a mobile station in Germany. [207] => [208] => INDEX (Reimei) is a small 70 kg satellite for testing various equipment, and functions as an [[Aurora (astronomy)|aurora]] observation mission as well.

Communication between ALOS and the ground station in Japan will be done through the Kodama Data Relay Satellite, which was launched during 2002. This project is under intense pressure due to the shorter than expected lifetime of the ADEOS II (Midori) Earth Observation Mission. For missions following Daichi, JAXA opted to separate it into a radar satellite ([[ALOS-2]]) and an optical satellite ([[ALOS-3]]). ALOS 2 SAR (Synthetic Aperture Radar) satellite was launched in May 2014. The ALOS 3 satellite was launched in March 2023. The satellite was lost in a launch failure. [219] => [220] => === Rainfall observation === [221] => Since Japan is an island nation and gets struck by typhoons every year, research about the dynamics of the atmosphere is a very important issue. For this reason Japan launched in 1997 the [[TRMM]] (Tropical Rainfall Measuring Mission) satellite in cooperation with NASA, to observe the tropical rainfall seasons. For further research NASDA had launched the ADEOS and ADEOS II missions in 1996 and 2003. However, due to various reasons,{{specify|reason=what would those reasons be?|date=November 2017}} both satellites had a much shorter than expected life term. [222] => [223] => On 28 February 2014, a H-2A rocket launched the [[GPM Core Observatory]], a satellite jointly developed by JAXA and NASA. The GPM mission is the successor to the TRMM mission, which by the time of the GPM launch had been noted as highly successful. JAXA provided the [[Global Precipitation Measurement]]/Dual-frequency Precipitation Radar (GPM/DPR) Instrument for this mission. Global Precipitation Measurement itself is a satellite constellation, whilst the GPM Core Observatory provides a new calibration standard for other satellites in the constellation. Other countries/agencies like France, India, ESA, etc. provides the sub-satellites. The aim of GPM is to measure global rainfall with unprecedented detail. [224] => [225] => === Monitoring of carbon dioxide === [226] => At the end of the 2008 fiscal year, JAXA launched the satellite [[GOSAT]] (Greenhouse Gas Observing SATellite) to help scientists determine and monitor the density distribution of [[carbon dioxide]] in the [[Earth's atmosphere|atmosphere]]. The satellite is being jointly developed by JAXA and Japan's [[Ministry of the Environment (Japan)|Ministry of the Environment]]. JAXA is building the satellite while the Ministry is in charge of the data that will be collected. Since the number of ground-based carbon dioxide observatories cannot monitor enough of the world's atmosphere and are distributed unevenly throughout the globe, the GOSAT may be able to gather more accurate data and fill in the gaps on the globe where there are no observatories on the ground. Sensors for [[methane]] and other [[greenhouse gas]]ses are also being considered for the satellite, although the plans are not yet finalized. The satellite weighs approximately 1650 kg and is expected to have a life span of five years. [227] => [228] => The successor satellite [[Greenhouse Gases Observing Satellite-2|GOSAT 2]] was launched in October 2018. [229] => [230] => === GCOM series === [231] => The next funded Earth-observation mission after GOSAT is the GCOM ([[Global Change Observation Mission]]) Earth-observation program as a successor to ADEOS II (Midori) and the [[Aqua (satellite)|Aqua]] mission. To reduce the risk and for a longer observation time the mission will be split into smaller satellites. Altogether GCOM will be a series of six satellites. The first satellite, [[GCOM-W]] (Shizuku), was launched on 17 May 2012 with the H-IIA. The second satellite, [[GCOM-C]] (Shikisai), was launched in 2017. [232] => [233] => == Satellites for other agencies == [234] => For weather observation Japan launched in February 2005 the Multi-Functional Transport Satellite 1R ([[MTSAT|MTSAT-1R]]). The success of this launch was critical for Japan, since the original MTSAT-1 could not be put into orbit because of a launch failure with the H-2 rocket in 1999. Since then Japan relied for weather forecasting on an old satellite which was already beyond its useful life term and on American systems. [235] => [236] => On 18 February 2006, JAXA, as head of the H-IIA at this time, successfully launched the MTSAT-2 aboard a H-2A rocket. MTSAT-2 is the backup to the MTSAT-1R. The MTSAT-2 uses the [[DS2000]] satellite bus developed by Mitsubishi Electric.{{cite web |url=http://www.mitsubishielectric.co.jp/society/space/products/platform_b.html |title=製品のご紹介製品・衛星プラットフォーム／DS2000 |language=ja |publisher=Mitsubishi Electric |access-date=3 August 2008 |archive-url = https://web.archive.org/web/20080822142407/http://www.mitsubishielectric.co.jp/society/space/products/platform_b.html |archive-date = 22 August 2008}} The DS2000 is also used for the DRTS Kodama, ETS-VIII and the Superbird 7 communication satellite, making it the first commercial success for Japan.
