Abstract
Inside the Space Shuttle and the International Space Station, it is not completely weightless. The difference from the weightlessness is called - g-jitter- In a lot of space experiments, the influence of the g-jitter on their results has been adversely reported. To extend our understanding on the g-jitter systematically, a working group has been organized under the JASMA. The working group already held a few research meetings. Some presentations made at the meetings are briefly introduced.
