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] |
STARS-II
Space Tethered Autonomous Robotic Satellite II or STARS-II, was a nanosatellite built by Japan's Kagawa University to test an electrodynamic tether in low Earth orbit, a follow-on to the STARS mission. STARS-II was launched by an H-IIA rocket, flying in the 202 configuration, as a secondary payload aboard the launch of the GPM Core Observatory on 27 February 2014. After two months in orbit, STARS-II reentered the atmosphere on 26 April 2014.

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. The satellite decayed from orbit on 10 June 2022. Overview RSP-01 was Ryman Sat Project's second satellite. It was a 1U CubeSat weighing around 1.3 kg, and was equipped with an arm that could extend up to 10 cm. The CubeSat had three transceivers. The on board computer used Arduino and Raspberry Pi. The project began in 2017, and development was completed by 2020. Part of the development cost was covered by a crowdfunding campaign in 2019. The RSP-01 project was led by Ryuichi Mitsui and Shuichi Ito. Mission RSP-01's main mission was to extend an arm carrying a camera, and photograph RSP-01 with the Earth in the background, taking selfies. The arm had a pantograph design to allow contraction after being extended. Additionally, RSP-01 conducted image recognition by machine learning, and ...

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.

Spacecraft Launched In 2021
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ( space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2021 In Japan

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, ...

Space Elevator
A space elevator, also referred to as a space bridge, star ladder, and orbital lift, is a proposed type of planet-to-space transportation system, often depicted in science fiction. The main component would be a cable (also called a tether) anchored to the surface and extending into space. The design would permit vehicles to travel up the cable from a planetary surface, such as the Earth's, directly into orbit, without the use of large rockets. An Earth-based space elevator could not feasibly be simply a tall tower supported from below, due to the immense weight - instead it would consist of a cable with one end attached to the surface near the equator and the other end attached to a counterweight in space beyond geostationary orbit (35,786 km altitude). The competing forces of gravity, which is stronger at the lower end, and the upward centrifugal force, which is stronger at the upper end, would result in the cable being held up, under tension, and stationary over a singl ...

Nanosatellite
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 ...
