Warpspace
Warpspace is a private Japanese company developing an inter-satellite communication system based on laser communication. Warpspace is developing a medium Earth orbit satellite, WarpHub InterSat, which will communicate with other satellites in low Earth orbit using optical communication, then pass on the received data to ground stations. History Warpspace was founded in 2016 as a spin-off company of Tsukuba University. In 2017, the company tested a mobile ground control station, receiving data from Tsukuba University's ITF-2 CubeSat in low Earth orbit. In July 2018, Warpspace announced a 'space bridal service' in which wedding plaques were to be sent to space, by placing them on a satellite and releasing it from the International Space Station (ISS). According to media reports, astronauts staying on the ISS were to take photographs of the satellite during its deployment. The company signed a contract to deploy a satellite from the ISS's Kibo Module on 24 August 2018. In February ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Laser Communication In Space
Laser communication in space is the use of free-space optical communication in outer space. Communication may be fully in space (an inter-satellite laser link) or in a ground-to-satellite or satellite-to-ground application. The main advantage of using laser communications over radio waves is increased bandwidth, enabling the transfer of more data in less time. In outer space, the communication range of free-space optical communication is currently of the order of hundreds of thousands of kilometers,. Laser-based optical communication has been demonstrated between the Earth and Moon and it has the potential to bridge interplanetary distances of millions of kilometers, using optical telescopes as beam expanders. Demonstrations and tests Before 1990 On 20 January 1968, the television camera of the Surveyor 7 lunar lander successfully detected two argon lasers from Kitt Peak National Observatory in Arizona and Table Mountain Observatory in Wrightwood, California. 1991-200 ...

Cygnus NG-15
NG-15, previously known as OA-15, was the fifteenth launch of the Northrop Grumman robotic resupply spacecraft Cygnus and its fourteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS) contract with NASA. The mission launched on 20 February 2021 at 17:36:50 UTC. This is the fourth launch of Cygnus under the CRS-2 contract. Orbital ATK (now Northrop Grumman Innovation Systems) and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation Services (COTS) program, Orbital ATK designed, acquired, built, and assembled these components: Antares, a medium-class launch vehicle; Cygnus, an advanced spacecraft using a Pressurized Cargo Module (PCM) provided by industrial partner Thales Alenia Space of Turin, Italy, and a Service Module based on the Orbital GEOStar satellite bus.

Private Spaceflight
Private spaceflight is spaceflight or the development of spaceflight technology that is conducted and paid for by an entity other than a government agency. In the early decades of the Space Age, the government space agencies of the Soviet Union and United States pioneered space technology in collaboration with affiliated design bureaus in the USSR and private companies in the US, entirely funding both the development of new spaceflight technologies and the operational costs of spaceflight. The European Space Agency was formed in 1975, largely following the same model of space technology development. However, Arianespace became the world's first commercial launch service provider in the early 1980s. Later on, large defense contractors began to develop and operate space launch systems, derived from government rockets. Private spaceflight in Earth orbit includes communications satellites, satellite television, satellite radio, astronaut transport and sub-orbital an ...

Shinto
Shinto () is a religion from Japan. Classified as an East Asian religion by scholars of religion, its practitioners often regard it as Japan's indigenous religion and as a nature religion. Scholars sometimes call its practitioners ''Shintoists'', although adherents rarely use that term themselves. There is no central authority in control of Shinto, with much diversity of belief and practice evident among practitioners. A polytheistic and animistic religion, Shinto revolves around supernatural entities called the . The are believed to inhabit all things, including forces of nature and prominent landscape locations.

Sacred Mountain
Sacred mountains are central to certain religions, and are usually the subjects of many legends. For many, the most symbolic aspect of a mountain is the peak because it is believed that it is closest to heaven or other religious realms. Many religions have traditions centered on sacred mountains, which either are or were considered holy (such as Mount Olympus in Greek mythology) or are related to famous events (like Mount Sinai in Judaism, Christianity and descendant religions or Mount Kailash in Hinduism). In some cases, the sacred mountain is purely mythical, like the Hara Berezaiti in Zoroastrianism. Mount Kailash is believed to be the abode of the deities Shiva and Parvati, and is considered sacred in four religions: Hinduism, Bon, Buddhism, and Jainism. Volcanoes, such as Mount Etna in Italy, were also considered sacred, Mount Etna being believed to have been the home of Vulcan, the Roman god of fire and the forge.

Space Development Agency
The Space Development Agency (SDA) began as a directorate of the United States Department of Defense's office of the under secretary of defense for research and engineering ( OUSD (R&E)) which supports space development in the interests of U.S. national security. The SDA was conceived by Mike Griffin and established in 2019 after his appointment to USD (R&E) early in the Trump Administration. A top priority is to implement the National Defense Space Architecture ( NDSA), using spiral models for its development method. While initial leadership sought more aggressive capabilities including space-based interceptors similar to the Strategic Defense Initiative, the Biden Administration has since refocused on sensing and arms control. The SDA transferred to the United States Space Force October 1, 2022.

Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SP ...
