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 ...

HOPE-X
HOPE (H-II Orbiting Plane) was a Japanese experimental spaceplane project designed by a partnership between NASDA and NAL (both now part of JAXA), started in the 1980s. It was positioned for most of its lifetime as one of the main Japanese contributions to the International Space Station, the other being the Japanese Experiment Module. The project was eventually cancelled in 2003, by which point test flights of a sub-scale testbed had flown successfully. History The original HOPE project called for the building of a sub-scale orbital prototype known as HOPE-X, for H-II Orbiting Plane, Experimental. This would be used for flight testing and systems validation, before moving onto the larger HOPE, which used many of the same parts and general design in a 4-man design. As the name implies, both would be launched on Japan's new H-2 launcher, the full-scale HOPE requiring substantial upgrades in performance. At the time, Japan was an up-and-coming industrial powerhouse, and their spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ALFLEX
ALFLEX (Automatic Landing Flight EXperiment) was an experimental unmanned aircraft created by NASDA and NAL, the predecessors of JAXA, in 1996. It was built as a successor to HYFLEX as part of the HOPE program. ALFLEX was built to establish the basic technology of automatic landing. The design featured a streamlined metal hull, delta planiform wings, and large winglets. Despite being a project of Japanese aerospace agencies, ALFLEX never left the atmosphere. Instead, it was carried up to a high altitude by a helicopter, then released to automatically glide down to the designated landing site, navigating by means of onboard computers. ALFLEX completed thirteen drop tests from July to August 1996, all of which were successful. Specifications (ALFLEX) * Length (without pitot boom): 6.10 m * Wingspan: 3.78 m * Height (without gear): 1.35 m See also * HOPE-X * HYFLEX * OREX OREX (Orbital Re-entry Experiment) was a NASDA re-entry demonstrator prototype which was launched in 19 ...

HYFLEX
HYFLEX (Hypersonic Flight Experiment) was a National Space Development Agency of Japan reentry demonstrator prototype which was launched in 1996 on the only flight of the J-I launcher. It was a successor of OREX and was a precursor for the Japanese space shuttle HOPE-X. HYFLEX tested the carbon-carbon heat shielding tiles that were intended to be used on HOPE, as well as having the same body shaping in order to gather data on hypersonic lifting. HYFLEX flew in space at altitude and succeeded in re-entry, but sank in the Pacific after splashdown before it could be recovered. Overview HYFLEX was an uncrewed lifting body space plane for gaining technological prowess in the design, production, and flight of hypersonic crafts, as well as technology validation of atmospheric reentry. The experimental vehicle was covered in carbon–carbon, ceramic tiles, and flexible thermal insulation, which were materials that was to be used for HOPE. Launched on 11 February 1996 (UTC) from Tane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NASDA
The , or NASDA, was a Japanese national space agency established on October 1, 1969 under the National Space Development Agency Law only for peaceful purposes. Based on the Space Development Program enacted by the Minister of Education, Culture, Sports, Science and Technology (MEXT), NASDA was responsible for developing satellites and launch vehicles as well as launching and tracking them. The first launch vehicles of NASDA ( N-I, N-II, and H-I) were partially based on licensed technology from the United States, particularly the Delta rocket family. The H-II was the first liquid fuel rocket to be fully developed in Japan. Hideo Shima, chief engineer of the original Shinkansen "bullet train" project, served as Chief of NASDA from 1969 to 1977. On October 1, 2003, NASDA merged with the Institute of Space and Astronautical Science (ISAS) and the National Aerospace Laboratory of Japan (NAL) into one Independent Administrative Institution: the Japan Aerospace Exploration Agency ...

Tanegashima Space Center
The (TNSC) is the largest rocket-launch complex in Japan with a total area of about 9.7 square kilometers. It is located on the southeast coast of Tanegashima, an island approximately south of Kyushu. It was established in 1969 when the National Space Development Agency of Japan (NASDA) was formed, and is now run by JAXA. The activities that take place at TNSC include assembly, testing, launching, and tracking satellites, as well as rocket engine firing tests. Facilities On-site main facilities include: * Yoshinobu Launch Complex is a launch site for launch vehicles like the H-IIA * Vehicle Assembly Building (VAB) * Second Spacecraft Test and Assembly Building * Takesaki Range Control Center Those facilities are used for performing operations from assembling launch vehicles, maintenance, inspections, final checks of satellites, loading satellites onto launch vehicles, rocket launches, and tracking launch vehicles after liftoff.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

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] |
