RAPIS-1
RAPIS-1 (RAPid Innovative payload demonstration Satellite 1) is a satellite launched on 18 January 2019 which for over a year was used to test seven technology demonstration projects. RAPIS-1 was developed and operated by Axelspace Corporation, under the coordination of the Japanese space agency JAXA. Overview RAPIS-1 was the main satellite of the Innovative Satellite Technology Demonstration-1 mission. RAPIS-1 demonstrated various projects attached to it as either parts or components. The call for proposals for this mission was announced in 2015, and selection results were announced in February 2016. Of the 13 projects selected for Innovative Satellite Technology Demonstration-1, 7 were on board RAPIS-1. A total of eight projects was initially selected, but a proposal by IHI Corporation, the "Demonstration experiment of a innovative ship information receiving system" was later dropped, making the number of projects sent to space on board RAPIS-1 seven.

Japan Space Systems
The was a Japanese space agency, which was founded by the Ministry of International Trade and Industry in 1986. Unlike NASDA, ISAS, and NAL, it was not included in the JAXA organization, which was founded in 2003. The chairperson is Ichiro Taniguchi. In 2012, USEF merged two other organizations— Earth Remote Sensing Data Analysis Center (ERSDAC) and Japan Resources Observation System Organization (JAROS)—to form a new organization Japan Space Systems (J-spacesystems). Goal The aim of USEF is technology development, especially the testing of commercial off-the-shelf parts ( COTS), robotics, material sciences and technology for optical earth observations. Launch vehicle Unlike the JAXA organisation, USEF doesn't have its own launch vehicle. Instead, it has used either the H-IIA, the M-3S, or Russian rockets, so far. However, in 2008, METI mentioned the possibility of USEF developing an air-launched vehicle for small payloads. Completed missions EXPRESS The Experiment R ...

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 ...

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 ...

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] |

Honeycomb Structure
Honeycomb structures are natural or man-made Structure, structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal Material costs, material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed between thin vertical walls. The cells are often columnar and hexagonal in shape. A honeycomb shaped structure provides a material with minimal density and relative high out-of-plane compression strength, compression properties and out-of-plane shear modulus, shear properties. Man-made honeycomb structural materials are commonly made by layering a honeycomb material between two thin layers that provide strength in Tension (physics), tension. This forms a plate-like assembly. Honeycomb materials are widely used where flat or slightly curved surfaces are needed and their high specific strength is valuable. They are widely us ...

Thin-film Solar Cell
A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si). Film thickness varies from a few nanometers ( nm) to tens of micrometers ( µm), much thinner than thin-film's rival technology, the conventional, first-generation crystalline silicon solar cell (c-Si), that uses wafers of up to 200 µm thick. This allows thin film cells to be flexible, and lower in weight. It is used in building-integrated photovoltaics and as semi-transparent, photovoltaic glazing material that can be laminated onto windows. Other commercial applications use rigid thin film solar panels (interleaved between two panes of glass) in some of the world's largest photovol ...
