Japanese space program
Japan's space exploration originated in the mid-1950s as a research group led by Hideo Itokawa at the University of Tokyo. Rocket sizes increased gradually from less than 30 cm (12 in) at the start of the project to over 15 m (49 ft) in the mid-1960s. The aim of the original research project was to launch a man-made satellite.
By the 1960s, two organizations, the Institute of Space and Astronautical Science (ISAS) and the National Space Development Agency of Japan (NASDA), were developing their own rockets. After experiencing numerous failures in the 1990s and 2000s, ISAS and NASDA merged — along with the National Aerospace Laboratory of Japan (NAL) — to form the unified Japan Aerospace Exploration Agency (JAXA) in 2003.
Japanese space development was started by Tokyo University professor Hideo Itokawa. Many aeronautical engineers lost their jobs after World War II as aircraft development was banned under the US Occupation of Japan. This changed after the signing of the San Francisco Peace Treaty in 1951, which once again allowed the development of aviation technology. The seven-year stagnation of Japan's aerospace industry had seriously harmed Japanese technical abilities. To address this, Itokawa established an aviation research group at the Institute of Industrial Science of the University of Tokyo. This institution succeeded in a horizontal launch of the Pencil Rocket on 12 April 1955 in Kokubunji, Tokyo. The dimensions of the rocket were 23 cm (9.1 in) in length by 1.8 cm (0.71 in) in diameter. 
The rocket was the first experiment of its kind in Japan. This rocket was initially associated with the development of rocket aircraft and not with space exploration. However, with Japan's participation in the International Geophysical Year, the focus of the rocket project shifted towards space engineering.
The Pencil Rocket eventually increased in size so that the experiment in the city outskirts was deemed too dangerous and the launch site was moved to Michikawa beach in Akita Prefecture. Following the Pencil Rocket, the larger Baby Rocket was developed which finally reached an altitude of 6 km (3.7 mi). After the Baby Rocket, two rocket projects were further carried out: a rockoon type rocket launched from a balloon and a ground-launched rocket. The development of the rockoon turned out to be difficult and was eventually stalled. Among the ground-launched rocket type, the Kappa rocket was one of the most successful, reaching altitudes that gradually increased over time. This rocket was also used for weather observation and participated in the data collection of the 1958 International Geophysical Year. Due to inadequate development funds at the time, the rockets were handmade and the tracking radar was operated manually. The production relied on trial and error, which brought forth many types of rockets.
In 1958, the Kappa 6 rocket reached an altitude of 40 km (25 mi) and the collected data allowed Japan to participate in the International Geophysical Year. In 1960, the Kappa 8 rocket exceeded an altitude of 200 km (120 mi). The development of larger rockets necessitated a launch site with a big downrange. The old site in Akita prefecture opening to the narrow Sea of Japan was deemed insufficient for this purpose and a new launch site opening to the Pacific was again created, this time at Uchinoura in Kagoshima Prefecture.
Launch of Ohsumi
In the 1960s, the information collected was primarily focused on satellites. A tentative plan was hatched whereby the Kappa Lambda rocket became the successor of this rocket, and the agency subsequently focused on gathering technical information from these launches in order to achieve higher maximum altitudes.
In 1963, the Science and Technology Agency established the National Aerospace Laboratory (NAL) where basic research on space technology was to be conducted. From about that time, the government started to gradually increase its effort with regard to space development. National Aerospace Laboratory is the insufficient development of space technology for facilities, the National Aerospace Laboratory separated only aviation technology, 1964 in STA is another as an institution, "Space Development Group," has been established.
The University of Tokyo Aerospace division was established. Although the Lambda rocket development proceeded slowly, there were incremental improvements such as the new capability to reach 2000 km altitude, a figure that edged the scientists' efforts closer to the launch of a satellite. At this time, however, rocket technology became a political issue further stalling its development. There was, for instance, the controversy involving rocket guidance technologies, which some perceived to fall within military affairs. This was further aggravated by the continued failure of the Lambda rocket initiative, which lostt four Lambda in orbit. The failure was reportedly caused by a shake that caused parts to slam against each other.
On February 11, 1970, the unguided banner L-4S rocket by orbiter from Japan the No. 5 Ohsumi was successfully launched. This was welcomed by the locals with a celebration. The launch of Ohsumi was also important because it involved technological cooperation with the United States, particularly in the development of high efficiency batteries that did not lose power at high temperatures.
After the Space Development Group merged with ISAS and National Space Development Agency into one organization, space development started to achieve some success. Before this milestone, each of these agencies were developing their own rockets independently. For example, NASDA was focused on commercial applications rather than the improvement of liquid fuel rocket technology.
After the unification of the space agencies, Japan started to develop more precise rockets in the 1970s. Ohsumi launched a new rocket technology based on the L-4S Mu rocket. Although the first M-4S rocket failed, the next iterations of it succeeded in orbit, with three satellite aircraft eventually becoming the foundation of Mu. Afterwards, the Mu rockets were changed from four stages to three stages to simplify the system, and enhancements were made to M-3C. All stages were able to work with the M-3S rockets, and this technology resulted in a string of successful satellite launches into orbit, reaching higher altitudes each time.
As Engineering Test Satellite Tansei and many other scientific satellites were being launched by these rockets, ISAS began to store the information and satellite technology. Atmospheric observation satellites such as Kyokko and Ohzora and X-ray astronomy satellites such as Hakucho and Hinotori were also active at this time. ISAS's development of the rocket M-3SII rocket reached its completion. The rocket was the first solid fuel rocket of its kind, and left Earth's gravity carrying satellites Sakigake and Suisei of the Halley Armada. M-3SII established the technology for the satellites that were being launched one after another.
The M-V rocket, a larger solid rocket, made an appearance in 1997. ISAS reported to the government that it would not be technically possible to increase the diameter of the rocket to more than 1.4m in the next 10 years. This was because NASDA had decided on this size and the National Assembly had imposed further restrictions on top of it, making it difficult to increase the size.
NASDA initially planned to develop its own liquid fuel rocket. However, because of the pressing need for practical and commercial rockets, the Japan-U.S. space agreement was signed and technology from the United States was introduced. Using the American Delta rocket's first stage liquid fuel engine, development of the project for installing LE-3 with liquid rockets for second stage began in Japan. Thus, the N-I rocket had been developed. However, the capability to launch the first liquid rocket N-I Rocket to low orbit was inferior to the U.S.'s ability to produce satellites. Therefore, the 1977 geostationary meteorological satellites in the transfer of technology from the United States created by Himawari of the United States launched a rocket. The Sakura and Yuri had launched rockets such as the United States. N-I rocket technology was acquired only manufacturing technology and management techniques, often take the record, NASDA will gradually acquire technical skills, since the Himawari 2, it increased the localization went.
Since then, NASDA satellite to meet the requirements of N-I larger rocket, the successor to N-II rocket started the development of the second stage knock-down kit change, 300 kg close Himawari 2 was able to put into a geostationary orbit. These rockets United States in Delta rocket in licensed production and the U.S. component knockdown production vehicle itself and the quality was very good, the apogee kick motor and satellite black box not enter the information not yet made it even better when it fails has become. Thus, began the development of indigenous self-development that would require the entire rocket. The newly developed H-I rocket was a liquid fuel rocket research and development conducted on its own LE-5 engines to practical use, the second-stage rocket engine turned 2. LE-5 is characterized by this feature can be re-ignition becomes more powerful N-II, H-I capability of the rocket launch to geostationary orbit over 500 kg.
NASDA rockets are used for production of commercial satellite launch is much more rapid communication satellite and broadcasting satellites, meteorological satellites and the launch went. H-I consists of nine manufactured rockets, all of which successfully launched the satellite successfully launched multiple simultaneous first Japanese.
Japan has not been developed for manned space flight. Mouri Mamoru, in cooperation with NASA, was scheduled to go first as a Japanese space by the shuttle accident in 1990. Toyohiro Akiyama became the first Japanese national to go into space. He also became the first Japanese civilian man to go into space.
Integration and institutional failure
NASDA LE-5 engine will be successful, even in light of technological progress in Japan has decided to develop a purely domestic liquid fuel rocket technology to improve domestic technology. The development was initiated from 1984. H-II rocket is a redesign everything from scratch. Toward the domestic first-stage engine completely, with difficulties in its development. First stage was to develop a new type of Japan LE-7 rocket engines are used in high-pressure combustion of hydrogen and oxygen gas, or parts damage due to vibration, and durability of the material issues It took some time to resolve. Hydrogen is also caused by revealing the explosion. Solid rocket boosters had to take advantage of the solid rocket technology has continued research in space science laboratory. Takes years to develop 10, HI in the last two years after the launch [in 1994] decided to launch one rocket. [February 3,] was scheduled to be launched to put off a day fell from the launch pad for air conditioning duct fairing February 4, as the first complete domestic and liquid rocket became H-II rocket was launched in a rocket.
On the other hand, the 1989 Space Science Institute [Space Development policy outline] enables the development of larger rockets conversions began in 1990 to develop rockets with solid rocket can planets. Problem occurs also in the development of rocket motors. The prolonged development, M-3SII again in 1997 after two years from the last flight of the rocket M-V was completed. Was born during a space launch vehicle for spacecraft Mars Nozomi was to postpone the launch of two years.
Japan was thus advanced the development of a rocket,  (1990) and the USA trade policy, "Section 301" is applied, Japan international competitive bidding had to be practical for use in domestic satellites. This is useful for satellite launches, a lot to bring the US-made rocket that can launch more affordable, and produced a few high-cost domestic satellite, a commercial satellite in low-cost mass production of the West slightly enemy Himawari 5 was the successor to purchase American-made finished products. Midori and environmental observation satellites for such, HALCA astronomical satellites and experimental spacecraft and satellites is almost like a rocket can be launched in Japan, gave a great success of these satellites. However, it flowed overseas launch of commercial satellites is also the reason can not gain experience until now launch commercial rockets.
The late 1990s and early 2000s (decade) was to stumble on a newly developed rocket. H-II rocket flight 5 and flight 8 failed to launch in a row, M-V failed to launch even flight 4. Nozomi failed to enter Mars orbit. Overlapping administrative reform movement from these failures and the occasion was to be proposed in the integration of government space agencies. Strengthening cooperation between organizations, prioritization of features, such as being a plan to streamline the organizational structure, Space Science Institute, October 1, 2003 (ISAS), National Space Development Agency (NASDA), aerospace Technology Laboratories (NAL) are integrated, Japan Aerospace Exploration Agency was established. Integration was the first time since the launch of a space agency H-IIA flight 6, but failed to launch, the rocket launches have been successful since.
NASDA H-II we redesigned and simplified from a failed rocket launch H-IIA rocket was developed. Although this rocket failed shortly after launch integration, which will launch and many successful aircraft in 17 aircraft by September 18, 2010. Large payload to send equipment and supply to the international space station more H-IIB Rocket have been developed and is now in order to launch the satellite easier cheaper MV solid fuel new successor to the Rocket Rocket Epsilon rocket is also being developed. These developments in Japan are pursuing the possibility of re-launching business.
Now a lot of satellites and experimental spacecraft to launch satellites in the country, became a strong technical capabilities in this field. No. 7 meteorological satellite Himawari can reduce costs by using satellite bus that was used to Kiku No. 8, was able to launch a domestic satellite weather again. Has been launched plans to launch a small scientific satellite lot, this plan is to allow for rapid development of inexpensive, custom-made satellites aims to share some semi.
On the other hand, 1998 after missile tests by North Korea in the past, has never been done spy satellites is done and now the launch of the basic space law in 2008 finalized, now is made military use of space for defense purposes only. And is currently doing in this area and although the Japanese reconnaissance satellite and missile defense only. Budget has been diverted out of scientific space exploration budget for these plans, which put pressure on other technologies. Space budget from other political factors tend to decrease. In addition, some factions of the organization state that the former JAXA affect the budget allocation. These are contributes to dampen the history of the Japanese space development.
The biggest success in recent years Hayabusa said feedback. Made the primary purpose of engineering experiments is the spacecraft in 2003 Uchinoura Space Center from MV asteroid was launched by rocket asteroid After exploring the 2010 returned to Earth. There was a problem during landing when the landing on Itokawa, which had been most likely unable to collect samples of the asteroid, which contains a sample of asteroids in the capsules were returned, by which the spacecraft World The spacecraft was first brought back samples from an asteroid.
In June 2014 Japan's science and technology ministry said it was considering a space mission to Mars. In a ministry paper it indicated unmanned exploration, manned missions to Mars and long-term settlement on the Moon were objectives, for which international cooperation and support was going to be sought.
Japan's space development Institute of Industrial Science, which began as a study group, and are based on the Engineering of Tokyo was the second aircraft before the war and developing sources I follow it. This study group in 1964 [Tokyo Institute of Aerospace] as an independent. In 1963, the State National Aerospace Laboratory launched, along with aircraft technology that it was done by National Aerospace Laboratory. 1969 NASDA was launched, Aerospace R & D technology exports grew from problems specific to science. Then in 1981, the Aerospace was reorganized and became the National Institute of Space and Astronautical Science. The momentum of reforms and administrative arrangements-government organizations held in the early 2000s (decade) from the 1990s, overlapping the failure of the launch rocket, a consistent these institutions are necessary to strengthen cooperation organization, Japan Aerospace Exploration Agency (JAXA) was launched. Currently, Japan's space development JAXA is responsible for one hand.

There are two facilities in Japan with the ability to launch satellites: the Tanegashima Space Center and Uchinoura Space Center. NASDA liquid fuel rockets are launched from Tanegashima, while ISAS solid fuel rockets are launched from Uchinoura.
In addition to the above two locations, there are other facilities able to launch test rockets.
Akita Rocket Test Site was used as a test launch facility since 1955 from the University of Tokyo. This test site was used for the last time in 1965 by the National Aerospace Laboratory, and now only a monument remains to commemorate the site.
The [rocket weather station] was established in April 1970 and was active until March 21, 2001. The MT-135P rocket was launched a total of 1,119 times. We are currently observing the atmosphere as air quality stations.
[Shima Shin test site] rocket launch test was conducted over the Science and Technology in 1963 and 1965. The agency and the facility had been rented in the form tested. Aviation is currently a Branch Office of Research and Shima Shin equipped laboratory, we have launched trial operations of guided missiles and other weapons.
Also, in Japan is one of the Antarctic bases, Showa Station. Between 1970 and 1985, rockets have been launched by 54 groups for purposes such as ozone measurements and auroral observation.
Japan is a "safe and prosperous society" that wants to use aerospace technology to achieve progress, according to JAXA's long-term vision.
- Natural disasters, support system for environmental issues
- Planetary sciences, and technical research for the advancement of asteroid exploration
- Improved reliability for stable transportation, related research and manned space activity
- Key industries
And has been incorporated.
Japanese rocket has been developed completely separated from the military technology for peaceful goals. Therefore, the purpose is commercial or scientific purposes with a lot of rockets and satellites. The initial observation satellites, a lot has been increasing and communications satellites and spacecraft gradually. Lead to the re-entry to military technology were ahead of 1994.
