Epsilon (rocket)
The Epsilon Launch Vehicle, or (formerly ''Advanced Solid Rocket''), is a Japanese solid-fuel rocket designed to launch scientific satellites. It is a follow-on project to the larger and more expensive M-V rocket which was retired in 2006. The Japan Aerospace Exploration Agency (JAXA) began developing the Epsilon in 2007. It is capable of placing a 590 kg payload into Sun-synchronous orbit. Vehicle description The development aim is to reduce the US$70 million launch cost of an M-V; the Epsilon costs US$38 million per launch. Development expenditures by JAXA exceeded US$200 million. To reduce the cost per launch the Epsilon uses the existing SRB-A3, a solid rocket booster on the H-IIA rocket, as its first stage. Existing M-V upper stages will be used for the second and third stages, with an optional fourth stage available for launches to higher orbits. The J-I rocket, which was developed during the 1990s but abandoned after just one launch, used a similar design concept, wi ...

RAISE-3
RAISE-3 (RApid Innovative payload demonstration SatellitE-3) is a smallsat for technology demonstration developed by Mitsubishi Heavy Industries (MHI). Part of the Japanese space agency JAXA's Innovative Satellite Technology Demonstration Program, RAISE-3 carried multiple technologies that were selected for in-orbit demonstration. RAISE-3 was launched on 12 October 2022 by an Epsilon rocket as the main satellite of Innovative Satellite Technology Demonstration-3, but the launch resulted in a failure and the satellite was lost. Overview For developing RAISE-3, JAXA selected MHI, the prime contractor of Japan's H-IIA and H3 rockets. MHI also previously developed Z-Sat, a satellite launched in 2021 as part of the Innovative Satellite Technology Demonstration-2 mission. While in orbit, RAISE-3 would have been operated from MHI's Nagoya Guidance & Propulsion Systems Works plant in Komaki, Aichi. The satellite carried 7 of the 15 themes that will be tested in Innovative Satellite Technol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellites Of Japan
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

MDS-1
Mission Demonstration Satellite 1 (MDS-1) or Tsubasa (COSPAR 2002-003A, SATCAT 27367) was a Japanese technology test mission. It was launched by the second H-2A on February 4, 2002 from the Tanegashima Space Center. After the launch, MDS-1 was renamed Tsubasa, meaning wings in Japanese. Tsubasa was placed in a geostationary transfer orbit (GTO). It ended its operational phase on 26 February 2003. A similar mission, MDS-2, was cancelled. The purpose of the mission was to test the performance of commercial off-the-shelf components, including solar batteries, semiconductors and computers. MDS-1 also carried instrumentation to observe how changes in the environment as the satellite passed through the Van Allen radiation belts affected the performance of each component. Among these instruments were a dosimeter using radiation-sensitive field effect transistors, a magnetometer, and a device for tracking heavy ions. During the mission, MDS-1 tracked the occurrence of single event ups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tohoku University
, or is a Japanese national university located in Sendai, Miyagi in the Tōhoku Region, Japan. It is informally referred to as . Established in 1907, it was the third Imperial University in Japan and among the first three Designated National Universities, along with the University of Tokyo and Kyoto University. Tohoku University is a Top Type university of the Top Global University Project, and since 2020 has been ranked the best university in Japan by Times Higher Education. In 2016, Tohoku University had 10 faculties, 16 graduate schools and 6 research institutes, with a total enrollment of 17,885 students. The university's three core values are "Research First (研究第一主義)," "Open-Doors (門戸開放)," and "Practice-Oriented Research and Education (実学尊重)." History On June 22, 1907(明治40年,''Mēji yonjyunen''), the university was established under the name by the Meiji government as the third Imperial University of Japan, following the Tokyo Imperi ...

Technology Demonstration
A technology demonstration (or tech demo), also known as demonstrator model, is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users. Computers and gaming Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development. * Computer game developers use tech demos to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing.

Smallsat
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multipl ...

JAXA
The is the Japanese national air and space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and launch of satellites into orbit, and is involved in many more advanced missions such as asteroid exploration and possible human exploration of the Moon. Its motto is ''One JAXA'' and its corporate slogan is ''Explore to Realize'' (formerly ''Reaching for the skies, exploring space''). History On 1 October 2003, three organizations were merged to form the new JAXA: Japan's Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL), and National Space Development Agency of Japan (NASDA). JAXA was formed as an Independent Administrative Institution administered by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Internal Affairs and Communications (MIC).
