NASA plans called for the station, which was later dubbed Space Station Freedom, to function as an orbiting repair shop for satellites, an assembly point for spacecraft, an observation post for astronomers, a microgravity laboratory for scientists, and a microgravity factory for companies.
ISAS| Hybrid Rocket"CAMUI"/ The Forefront of Space Science Application for experimental small launcher We are now proceeding with development of a larger-size CAMUI hybrid rocket for practical use as a small launcher for meteorologica lobservation and microgravity experiments.
Although the majority of space programs have moved away from using larger mammals, insects, fish, and small mammals are still routinely used to study the effects of microgravity, radiation, and other effects encountered while spending time in space.
Since then, he has been contributed to four research projects:‘rocket developments,'‘experiments on microgravity,' which creates the zero-gravity environment like space,‘developments of a miniaturized satellite,' and‘cooperative projects with American private space development corporations.'.
This analysis is useful for study not only on the impact of microgravity or space radiation, but also into the relationship between the space environment and oxidative stress, cell cycle, and the dynamic state of various gene groups related to aging, life-span, and so on.
Gioia Massa, a scientist working on the Veggie project, said the plants grown so far are not perfect but have helped researchers on Earth understand better how they grow in conditions of microgravity.
As the Asia's only pariticipating country, Japan takes advantage of the unique environment of the ISS, e.g. microgravity and space radiation, conducts various science experiments, such as material sciences and life sciences, space medical experiments to minimize astronauts' health risk, and the creation of high quality protein crystals which will lead to the discovery of new medicines.
ISAS| Hybrid Rocket"CAMUI"/ The Forefront of Space Science Introduction The main purpose of rockets launched from the ground is to put satellites into orbit around the earth. In addition, rockets are frequently used for academic purposes such as the aerological weather observation and microgravity experiments, by performing ballistic flight to 50 to 1,000km altitude.
The WG themes for the fundamental-science field as of FY2005 are as follows: Dusty plasmas under microgravity environment Dynamics near the critical point Liquid/solid helium under microgravity Microgravity science of nonequilibrium chemical physics Microgravity chemistry of mesoscopic system Development of a refrigerator suitable for the space environment for cryogenic experiments From these, I will introduce examples of on-going research, dusty plasmas and dynamics near the critical point.
The research group of the University of Yamanashi, which has conducted diverse research on mammalian reproduction to date, also reported an on-ground simulation experiment related to reproduction in space.(Note 1) Hampered by the difficulty to precisely realize a stable and long-term microgravity and cosmic radiation environment on the ground as in space, the group has been exploring ways to examine the influence on reproductive cells in the actual space environment.
