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 ...

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 Feb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
RSP-01
RSP-01, nicknamed Selfie-sh was a nanosatellite developed by Ryman Sat Project. RSP-01 launched from Wallops Flight Facility on board a Cygnus spacecraft on 20 February 2021.

OPUSAT-II
OPUSAT-II (COSPAR 1998-067SG, SATCAT 47930) was a CubeSat developed by Osaka Prefecture University and Muroran Institute of Technology. OPUSAT-II was launched from Wallops Flight Facility on 20 February 2021, and was deployed from the International Space Station. The satellite was nicknamed HIROGARI, for a Japanese word meaning spread, or expand. Spacecraft The satellite's satellite bus was based on the design of Osaka Prefecture University's previous satellite, OPUSAT, which was launched in 2014. OPUSAT-II had a design life of five and a half months. Mission OPUSAT-II had two main missions. The first mission was to demonstrate high-speed data transmission in amateur radio band. According to the project's website, the satellite communication system's design and the results of the experiment would be made public. The second mission was a deployment of a large folded structure. A deployable plastic plate was stored inside the satellite, based on Miura fold. The folding method t ...

Cygnus (spacecraft)
Cygnus is an expendable American cargo spacecraft developed by Orbital Sciences Corporation and now manufactured and launched by Northrop Grumman Space Systems as part of NASA's Commercial Resupply Services (CRS) program. It is launched by Northrop Grumman's Antares rocket or ULA's Atlas V and is designed to transport supplies to the International Space Station (ISS) following the retirement of the American Space Shuttle. Since August 2000, ISS resupply missions have been regularly flown by the Russian Progress spacecraft, as well as by the European Automated Transfer Vehicle, and the Japanese H-II Transfer Vehicle. With the Cygnus spacecraft and the SpaceX Dragon, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry. ''Cygnus'' is the Latinized Greek word for swan and a northern constellation.

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, ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
