Space Inflatable Structures
Inflatable structures, a typical example of which is the Tokyo Dome, have many advantages, such as the provision of a large space, light weight and few mechanical components. These features are also effective and advantageous in space. This article outlines technologies for the three processes - deployment, inflation and curing - required to build the structure and also introduces future applications in space. An article by Ken HIGUCHI at the website of Japan's Institute of Space and Astronautical Science.
Better Development of Attitude Control Systems for Satellites - Development Diary of REIMEI Satellite
The Aurora-observation satellite REIMEI launched in 2005 is a small 70kg satellite. Its unique concept was an insistence on in-house development as much as possible. This article reviews the lessons learned and troubles experienced in the development of the attitude control systems critical for observation satellites. These lessons are useful for future satellite development. An article by Shinichiro SAKAI at the website of Japan's Institute of Space and Astronautical Science.
User-friendly Nontoxic Liquid Propulsion System with Future Potential - Paving the Way to a New Era of Space Transportation -
Research is progressing on propulsion systems using nitrous oxide and ethanol as a nontoxic liquid propulsion system that can also be used in education. With firing experiments already complete, the next target is to develop a flight model in the next five years with the aim of introducing the engine to future solid rockets or reusable space-transportation systems. An article by Shinichiro TOKUDOME at the website of Japan's Institute of Space and Astronautical Science.
Visual Satellite Observer's Home Page
This web site provides information on all facets of visual satellite observation.
Solid Rocket Research Challenge: World's number one in the past and worlds' number one in the future
Japan is proud of its world-class solid rocket technology. In the next-generation solid-rocket system that will succeed the M-V rocket retired in 2006, we will simultaneously fulfill two competing requirements: high performance and low cost. In addition to improving the vehicle, we aim to innovate the launching system in order to enable frequent satellite launches. An article by Yasuhiro MORITA at the website of Japan's Institute of Space and Astronautical Science.
Jonathan's Space Report - Latest Issue
The Space Report ("JSR") is issued about twice a month. It describes all space launches, including both piloted missions and automated satellites. Provided by Dr. Jonathan McDowell.
Online Index of Objects Launched into Outer Space
The Online Index of Objects Launched into Outer Space provides a quick and efficient means to access information provided to the United Nations in accordance with the Convention on Registration of Objects Launched into Outer Space and General Assembly resolution 1721 B (XVI).
Lloyd's satellite constellations
These pages form an index to useful web information discussing satellite constellations. You won't gain a complete picture of what any proposed constellation is capable of, or really in-depth technical details, but you will gain an idea of what the developments in this area are, where the industry and technology is headed - and you will pick up background knowledge of satellites along the way.
Association of Space Explorers
The Association of Space Explorers (ASE) is an international nonprofit professional and educational organization of over 300 individuals from 32 nations who have flown in space.
Space Access Society
Forty-nine years into the Space Age, it still takes years of permits and planning and costs tens to hundreds of millions per mission to reach low Earth orbit, drastically constraining the otherwise huge opportunities. It isn't the laws of physics or engineering that are stopping us - there's nothing in either that prevents reusable rockets based on available technology from operating at costs and reliabilities a lot closer to modern airliners than to current rockets.
Space Tourism Society
Founded in 1996, the Space Tourism Society is the first organization specifically focused on the space tourism industry.
American Institute of Aeronautics and Astronautics
The American Institute of Aeronautics and Astronautics (AIAA) is the world's largest technical society devoted to the global aerospace community.
ProSpace - The CITIZENS' Space Lobby dedicated to opening the space frontier
ProSpace is a nonprofit citizens advocacy group (501-c4) with the mission "to open the space frontier for ALL people as rapidly as possible." We believe that only by taking direct and personal responsibility, as citizens of this great country, will our personal visions come to life.
The Adventures of ASTRO and NextSat
A pair of robots named ASTRO and NextSat have been working together in Earth orbit, docking, undocking, flying around and refueling, as if they have minds of their own. Their adventures may herald a revolution in the way we explore space.
Space debris: evolution in pictures
Between the launch of Sputnik on 4 October 1957 and 1 January 2008, approximately 4600 launches have placed some 6000 satellites into orbit, of which about 400 are travelling beyond geostationary orbit or on interplanetary trajectories.
New Antennas to Support a Variety of Scientific Observation Missions:Key Communication Equipment Capable of Withstanding a Harsh
High-performance antennas capable of withstanding the harsh space environment are essential for communication with both earth-orbiting satellites and planetary explorers far distant from the earth. Various types of antennas to support a variety of scientific missions are now researched and developed by introducing new ideas beyond the conventional design. An article by Yukio KAMATA at the website of Japan's Institute of Space and Astronautical Science.
Open Up New Routes in Outer Space
Trajectory design - setting the route of explorers from earth to a target body - is the first, basic task for space exploration missions. By using the swingby technique, it is possible to change an explorer's inclination or insert multiple explorers into different trajectories. This article uses examples to introduce the various attempts to open up new routes in outer space. An article by Yasuhiro KAWAKATSU at the website of Japan's Institute of Space and Astronautical Science.
Ceramics That Do Not Break Even When Cracked ~ Fiber-Reinforced Ceramics and Carbon Composite Materials
Although ceramics and carbon have excellent properties, such as high resistance to heat and chemicals, their weak point is “brittleness.” JAXA is now studying a variety of ceramics which rarely fracture through brittleness. The final goal is to develop a large, high-performance, fiber-reinforced ceramic combustion chamber, whose actual application is as yet unrealized in the world. An article by Ken GOTO at the website of Japan's Institute of Space and Astronautical Science.
