New Launch day of "KAGUYA"
The launch of the Lunar Orbit Explorer "KAGUYA" (SELENE) by H-IIA Launch Vehicle No. 13 (H-IIA F13) was rescheduled for 10:35:47 a.m. on September 13 (Thu), 2007, (Japan Standard Time) after replacement work on parts in the two onboard baby satellites of the "KAGUYA" was successfully completed. We plan to broadcast a live launch report on the launch day. Please enjoy it. Launch success of "S-310-37"
On January 16, the sounding rocket "S-310-37" was launched at 11:20 a.m. from the Uchinoura Space Center. The purpose of the rocket is to elucidate the mechanism of the generation of the high electron temperature sphere in the lower part of the ionosphere. The flight and operation of the on-board equipment went normally, and at 59 seconds after liftoff, the top part of the rocket opened. Subsequently, the rocket started observations at 60 seconds. All observations were completed after it reached its highest altitude of 138 km at 184 seconds, then it fell into the sea south-east of Uchinoura. The experiment went smoothly as planned, and through the on board electronic temperature measurement equipment we have confirmed that the high-temperature sphere existed at an altitude of 99 to 101 km.
Sounding rockets have been developed and launched by ISAS for more than 40 years. They have been dedicated to astrophysical observation, upper atmosphere exploration, space plasma physics, etc., for scientific research. Making use of these flight opportunities, ISAS engineering studies have also been conducted to demonstrate new vehicle systems such as attitude control systems, reentry flight technologies, recovery systems, new avionics, etc., some of which will be employed in the coming satellite launch vehicles and spacecraft. The community of micro-gravity utilization for both material research and life science also uses the sounding rockets.
The Tanegashima Space Center (TNSC) was established in 1969, when the original National Space Development Agency of Japan (NASDA) was formed. It is the largest space-development facility in Japan (9,700,000 square meters) and is located in the south of Kagoshima Prefecture, along the southeast coast of Tanegashima. It is known as the most beautiful rocket-launch complex in the world.On-site facilities include the Takesaki Range (for small rockets), the Osaki Range (for J-I and H-IIA launch vehicles), the Masuda Tracking and Communication Station, the Nogi Radar Station, the Uchugaoka Radar Station, and optical observation facilities to the west. There are also related developmental facilities for test firings of liquid and solid-fuel rocket engines.The TNSC’s main role is the management of satellites at every stage of flight including countdown, launching, and tracking. The TNSC is expected to play an increasingly important role as the demand for satellites grows.

Yoshinobu Firing Test Stand
This test stand was used for static firing tests on the first stage engine (LE-7), the heart of the 100% domestically manufactured H-II launch vehicle. The stand is now used for tests on the LE-7A, the first stage engine of the H-IIA.
Second Spacecraft Test and Assembly Building
Assembly, tests, and preparations for large spacecraft are performed at this facility.
Yoshinobu Launch Complex
A fully prepared and assembled launch vehicle is transported to a launch pad and loaded with liquid propellant for launch. There are two launch towers for large-scale launch vehicles. The Launch pad 1 is for up to a 2-ton geostationary spacecraft, while the Launch pad 2 is for 2- to 4-ton geostationary spacecraft.
Takesaki Range Control Center
The command and control of rocket launch operations for all systems are performed at this facility, including launch vehicles, satellites, ground facilities, tracking and weather systems.

Tours and Exhibits
The launch complexes are open to the general public, with the exception of periods when launch and engine tests are being carried out. The Space Exhibition Hall, located in the TNSC, enables visitors to study everything from space development to planets in easy and enjoyable ways. This includes exhibitions on such things as the mechanisms and functions of satellites; the launching, tracking and controlling of rockets; and the International Space Station project.
