OPUSAT
The Osaka Prefecture University Satellite, or OPUSAT was a technology demonstration cubesat built and operated by Japan's Osaka Prefecture University. It had a size of 100x100x100mm (without antennas and solar paddles) and build around a standard 1U cubesat bus. The primary satellite purpose was the space testing of the power system based on a Lithium-ion capacitor. The tests were largely successful, and it finished operation by reentry to Earth atmosphere on 24 July 2014. The OPUSAT was a development successor to “Maido Ichigo” satellite by East Osaka Craftmen Astro-Technology SOHLA in Osaka.

WARP-01
WARP-01, nicknamed Nichirin, was a 1U-sized CubeSat developed and operated by Warpspace, a newspace company based in Tsukuba, Japan. It was launched on 20 February 2021 on board a Cygnus cargo spacecraft, and deployed from the International Space Station (ISS) on 14 March 2021. WARP-01 was used for technology validation and monitoring the radio wave and radiation environment in space. Overview WARP-01 was Warpspace's first satellite. The company signed a contract to deploy a satellite from the ISS's Kibo Module with Space BD on 24 August 2018. Inside the satellite were several wedding memorial plaques, which were sent to space as part of a 'space bridal service'. At the time the service was first announced in July 2018, media reports said that astronauts staying on the ISS were to take photographs of the satellite during its deployment. WARP-01 was unveiled during an event in Tsukuba city in February 2020. WARP-01 was launched and carried to space on board Cygnus NG-15. WARP ...

STARS-EC
STARS-EC (Space Tethered Autonomous Robotic Satellite Elevator of CubeSat, COSPAR 1998-067SE, SATCAT 47928) was a nanosatellite developed by Shizuoka University, for the purpose of demonstrating space elevator tether technology. It was a 3U-size CubeSat, and could split into three separate satellites, connected via tethers. STARS-EC was launched on 20 February 2021, and was deployed from the International Space Station (ISS). The deployment service of STARS-EC was provided by Mitsui Bussan Aerospace. The satellite decayed from orbit on 15 April 2022. Mission STARS-EC's mission was to demonstrate space elevator tether technology using a 3U CubeSat. After deployment from the ISS, the satellite split into three separate spacecraft, each the size of a 1U CubeSat. The spacecraft on each end was connected to the center satellite by an space tether, thus putting the satellites on the ends 22 m apart from one another. The satellite in the center moved back and forth along the tether, demo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CubeSat
A CubeSat is a class of miniaturized satellite based around a form factor consisting of cubes. CubeSats have a mass of no more than per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. , more than 1,600 CubeSats have been launched. In 1999, California Polytechnic State University (Cal Poly) professor Jordi Puig-Suari and Bob Twiggs, a professor at Stanford University Space Systems Development Laboratory, developed the CubeSat specifications to promote and develop the skills necessary for the design, manufacture, and testing of small satellites intended for low Earth orbit (LEO) that perform a number of scientific research functions and explore new space technologies. Academia accounted for the majority of CubeSat launches until 2013, when more than half of launches were for non-academic purposes, ...

Satellites Deployed From The International Space Station
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, ...

2021 In Japan
2021 in Japan was largely defined by the COVID-19 pandemic and its impact on the country from one year on, in addition to various other historical events such as the postponement of the 2020 Tokyo Olympics and the economic recovery resulting from the pandemic. However, the pandemic was officially end by the early October 2021, as the country lifted the fourth and final state of emergency up and ahead of the endemic phase.

Space-based Solar Power
Space-based solar power (SBSP, SSP) is the concept of collecting solar power in outer space by solar power satellites (SPS) and distributing it to Earth. Its advantages include a higher collection of energy due to the lack of reflection and absorption by the atmosphere, the possibility of no (or very little) night, and a better ability to orient to face the sun. Space-based solar power systems convert sunlight to some other form of energy (such as microwaves) which can be transmitted through the atmosphere to receivers on the Earth's surface. It is attractive to those seeking large-scale solutions to anthropogenic climate change or fossil fuel depletion (such as peak oil). Various SBSP proposals have been researched since the early 1970s, but none is economically viable with present-day space launch costs. Some technologists speculate that this may change in the distant future with space manufacturing from asteroids or lunar material, or with radical new space launch techno ...

Osaka Prefecture University
(OPU), also abbreviated to , is one of the largest public universities in Japan. The main campus is among big Kofun tombs in Sakai, Osaka. The university will merge with Osaka City University to form Osaka Metropolitan University (OMU) in April 2022. History . OPU was established in 2005 in its current form by integrating three prefectural universities: University of Osaka Prefecture (), Osaka Women's University () and Osaka Prefecture College of Nursing (). In June 2020, OPU announced that it would be merging with Osaka City University to become the ''University of Osaka''. However, after the name was announced on June 26, 2020, Osaka University President released a statement pointing out that the English version of the new university's name was "remarkably similar" to that of Osaka University, adding, "It will cause confusion among our students, and work as a great obstacle for the future of both universities, which are reaching out to the world."

Miura Fold
The is a method of folding a flat surface such as a sheet of paper into a smaller area. The fold is named for its inventor, Japanese astrophysicist Kōryō Miura. The crease patterns of the Miura fold form a tessellation of the surface by parallelograms. In one direction, the creases lie along straight lines, with each parallelogram forming the mirror reflection of its neighbor across each crease. In the other direction, the creases zigzag, and each parallelogram is the translation of its neighbor across the crease. Each of the zigzag paths of creases consists solely of mountain folds or of valley folds, with mountains alternating with valleys from one zigzag path to the next. Each of the straight paths of creases alternates between mountain and valley folds.. Reproduced in ''British Origami'', 1981, and online at the British Origami Society web site. The Miura fold is related to the Kresling fold, the Yoshimura fold and the Hexagonal fold, and can be framed as a generalizati ...
