X103 H-IIB Launch Vehicle H-IIBロケット
Outdoor Exhibition Outdoor X103 H-IIB Launch Vehicle H-IIBロケット ■Purpose of Exhibition The domestically produced large rocket "H-IIB" is exhibited in the outdoor exhibition space. Most of this rocket has the same structure as the real rocket and served as a test. You can find the real parts in the chart including the first stage engine section, the first stage fuel tank, the center body section, the interstage adapter and the fairing, which are exhibited in the exhibition. The rest of the parts were made by referring to the actual rocket. When the rocket "H-IIB" is launched, two other main engines and four fixed rocket boosters are attached to the rocket. You can see the inside structure because the tank part is cut off. For making a light but strong rocket, it is manufactured like a honeycomb. For pouring low temperature liquid- hydrogen into the tank, the exterior of the rocket is coated by a thermal material. The rocket which is exhibited is also coated by using the same thermal material. Like this, the rockets were made by using the latest manufacturing technology and design techniques. We would like you to learn the structure of rocket and feel how big it is. ■Additional Knowledge Space Station had succeeded. The Japanese high- launching technology which put the rocket into the planned orbit accurately, and the connecting technology which controlled the HTV delicately and connected to the International Space Station in outer space, has been shown to the world. [The Other Rockets Exhibition in Japan] There are rocket exhibitions in regions where JAXA developed space technology (as of 2010).The Tanegashima Space Center is where the JAXA Research Institute is located in Tanegashima, Kagoshima Prefecture. -

Yet very little is known about this story, and about the politics and perceptions that are continuing to drive Japanese efforts despite many outright failures in the indigenization of the industry. This story, therefore, is important not just because of the widespread economic and technological merits of the space launch vehicles sector which are considerable. It is also important because it speaks directly to the ongoing debates about the Japanese developmental state and, contrary to the new wisdom in light of Japan's recession, the continuation of its high technology policy as a whole. -

1 SATELITES ARTIFICIALES. Capítulo 5º Subcap. 10 <> CRONOLOGIA DE LOS SATÉLITES ARTIFICIALES DE LA TIERRA. Esta es una relación cronológica de todos los lanzamientos de satélites artificiales de nuestro planeta, con independencia de su éxito o fracaso, tanto en el disparo como en órbita. Significa pues que muchos de ellos no han alcanzado el espacio y fueron destruidos. Se señala en primer lugar (a la izquierda) su nombre, seguido de la fecha del lanzamiento, el país al que pertenece el satélite (que puede ser otro distinto al que lo lanza) y el tipo de satélite; este último aspecto podría no corresponderse en exactitud dado que algunos son de finalidad múltiple. En los lanzamientos múltiples, cada satélite figura separado (salvo en los casos de fracaso, en que no llegan a separarse) pero naturalmente en la misma fecha y juntos. NO ESTÁN incluidos los llevados en vuelos tripulados, si bien se citan en el programa de satélites correspondiente y en el capítulo de “Cronología general de lanzamientos”. .SATÉLITE Fecha País Tipo SPUTNIK F1 15.05.1957 URSS Experimental o tecnológico SPUTNIK F2 21.08.1957 URSS Experimental o tecnológico SPUTNIK 01 04.10.1957 URSS Experimental o tecnológico SPUTNIK 02 03.11.1957 URSS Científico VANGUARD-1A 06.12.1957 USA Experimental o tecnológico EXPLORER 01 31.01.1958 USA Científico VANGUARD-1B 05.02.1958 USA Experimental o tecnológico EXPLORER 02 05.03.1958 USA Científico VANGUARD-1 17.03.1958 USA Experimental o tecnológico EXPLORER 03 26.03.1958 USA Científico SPUTNIK D1 27.04.1958 URSS Geodésico VANGUARD-2A -
Ssc11-I-9 Small Sar Satellite Using Small Standard
SSC11-I-9 SMALL SAR SATELLITE USING SMALL STANDARD BUS Kiyono bu Ono, Takashi Fujimura, Toshiaki Ogawa, Tsunekazu Kimura NEC Corporation 1-10 Nisshin-cho, Fuchu, Tokyo, Japan; +81 42 333 3940 [email protected] ABSTRACT This paper introduces a new small SAR (Synthetic Aperture Radar) satellite that follows the small optical sensor satellite, ASNARO. USEF, NEDO and NEC are developing ASNARO satellite, which is a small LEO satellite (total mass<500kg) with the high resolution (GSD <0.5m) optical earth observation sensor. For the next mission, NEC has started the development of a new small SAR satellite as one of small earth observation satellite series using our small standard bus. This small SAR satellite has the following features, i.e. high resolution of less than 1m, X-band sensor frequency and satellite mass of less than 500kg. The trial manufacturing of key technologies for SAR, such as a wide band signal generator / processor and an electronic power conditioner for a high power amplifier, has been developed and examined. 1. INTRODUCTION As the next mission following to ASNARO, NEC has started the development of a new small SAR satellite After the launch of first Japanese satellite OHSUMI, which was manufactured by NEC in 1970, NEC has using the same bus as ASNARO. been developing more than 60 satellites with Japan This paper introduces this new system. Aerospace Exploration Agency (JAXA) etc. During 40 years, not only the large satellites, such as DAICHI 2. ASNARO SYSTEM OUTLINE (ALOS), KAGUYA (SELENE) and KIZUNA (WINDS), but also many small satellites, such as The development of our small SAR satellite is based on HAYABUSA (MUSES-C), TSUBASA (MDS-1) and the technology of ASNARO. -
