HTV-X2
, tentatively called HTV-X, is an uncrewed expendable cargo spacecraft under development by Japan Aerospace Exploration Agency ( JAXA) as the successor of H-II Transfer Vehicle (HTV). the first flight is planned to be launched in January 2024 to resupply International Space Station. Development In May 2015, Japan's Ministry of Education, Culture, Sports, Science and Technology announced a proposal to replace the HTV with an improved, cost-reduced version preliminarily called HTV-X. The proposal of HTV-X is as follows: * To re-use the design of HTV's Pressurised Logistics Carrier (PLC) as much as possible, except for adding a side hatch for late cargo access after the spacecraft-launch vehicle integration. * To replace the Unpressurised Logistics Carrier (ULC), Avionics Module, and Propulsion Module with a new Service Module. * To load the unpressurised cargo on top of the Service Module rather than inside the spacecraft. Re-using the PLC design will allow minimizing the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JAXA
The is the Japanese national air and space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and launch of satellites into orbit, and is involved in many more advanced missions such as asteroid exploration and possible human exploration of the Moon. Its motto is ''One JAXA'' and its corporate slogan is ''Explore to Realize'' (formerly ''Reaching for the skies, exploring space''). History On 1 October 2003, three organizations were merged to form the new JAXA: Japan's Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL), and National Space Development Agency of Japan (NASDA). JAXA was formed as an Independent Administrative Institution administered by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Internal Affairs and Communications (MIC).

International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kounotori 9
, also known as HTV-9 was the 9th flight of the H-II Transfer Vehicle, a robotic cargo spacecraft to resupply the International Space Station (ISS). It was launched on 20 May 2020, at 17:31:00 UTC. Kounotori 9 is the last HTV of the original model, with following missions replaced with the HTV-X. Spacecraft Major difference from the previous Kounotori are: * Camera assembly unit and Wireless LAN communication unit (WLD), described below. Wireless LAN Demonstration Wireless LAN Demonstration, or WLD (pronounced wild) is an experiment that will be performed during Kounotori 9's flight. During the test, a video taken by Kounotori 9 will be broadcast in real time on board the space station, via a wireless LAN (WLAN) datalink.

Yoshinobu Launch Complex
Yoshinobu Launch Complex (LC-Y) is a rocket launch site at the Tanegashima Space Center on Tanegashima. The site and its collection of facilities were originally built for the H-II launch vehicle and later used for H-IIA and H-IIB launches. It is the most Northern launch complex at Tanegashima, and along with the now inactive Osaki Launch Complex used for orbital launches. The Yoshinobu Launch Complex consists of two launch pads. The complex also contains a test stand for firing the LE-7 engines used in the first stage of the H-II and its derivatives. Prior to launch, rockets are processed vertically in the complex's vehicle assembly building. The rocket is rolled out to the launch pad on a mobile launcher platform A mobile launcher platform (MLP), also known as mobile launch platform, is a structure used to support a large multistage space vehicle which is assembled (stacked) vertically in an integration facility (e.g. the Vehicle Assembly Building) and t ... about twelv ...

Geocentric Orbit
A geocentric orbit or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.

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] |
Uncrewed Spacecraft
Unmanned spacecraft or uncrewed spacecraft are spacecraft without people on board, used for robotic spaceflight. Uncrewed spacecraft may have varying levels of autonomy from human input; they may be Remotely operated vehicle, remote controlled, remote guided or even autonomous vehicle, autonomous, meaning they have a pre-programmed list of operations, which they will execute unless otherwise instructed. Many habitable spacecraft also have varying levels of robotic features. For example, the space stations Salyut 7 and Mir, and the International Space Station module Zarya (ISS module), Zarya, were capable of remote guided station-keeping and docking maneuvers with both resupply craft and new modules. The most common uncrewed spacecraft categories are robotic spacecraft, uncrewed resupply spacecraft, unmanned resupply spacecraft, space probed space observatory, space observatories. Not every uncrewed spacecraft is a robotic spacecraft; for example, a reflector ball is a non-ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
