日本宇宙开发事业团(NASDA)拟于1995年发射搭载老鼠、金鱼等生物的生命科学卫星,进行空间生物实验,其目的是为2000年前后航天员在空间站上长期驻留做实验准备,探求空间环境给予生物的影响。该计划是将搭载有生物实验装置的重约1吨的密闭舱,用NASDA于1992年开始研制的小型火箭J-1发射至高度为251～450km的低轨道上。在空间飞行约60天后,密闭舱将在海上回收。人在空间长期驻留,由于受到宇宙线的辐射及失重环境影响,存在
Japan’s Space Development Agency (NASDA) intends to launch life science satellites carrying mice, goldfish and other organisms in 1995 for space biology experiments aimed at providing long-term presence of astronauts to space stations for experimental preparation and space exploration in the year 2000 The environment gives biological influence. The plan is to launch an airtight capsule of about 1 tonne loaded with a biological experimental device onto a low orbit of 251-450 km using a small rocket J-1 developed by NASDA in 1992. After about 60 days of space flight, the airtight tank will be recovered at sea. Long-term presence of people in space, due to the cosmic ray radiation and weightlessness of the environment, there
