日本可能放弃“月球-A”探月计划日本宇宙航空研究开发机构1月16日证实,考虑到修理或重新打造探测器费用过高,该机构已向文部科学省宇宙开发委员会报告了放弃“月球-A”计划的意向,但委员会还要经过讨论和评估才能决定是否正式放弃这项计划。“月球-A”计划早在1991年就已启动,主要内容是1995年度发射月球探测器“月球-A”。“月球-A”计划携带两个穿透式着陆器,并在接近月球后将它们发射。这两个直径14厘米、长80厘米的矛状观测装置中配有地震仪和热流量计,观测装置可扎入月球表面1米至3米,对月球内部的构造、组成和热状态等进行探查。虽然探测器在1996年度就已开发成功,但如何使着陆器承受住扎入月球表面时的剧烈冲击却迟迟不能解决。经过6次延期,着陆器的研发问题已被攻破。然而此时,在仓库中沉睡10多年的探测器已严重老化,不能再发射。
Japan May Give Up “Lunar-A” Lunar Exploration Program JAXA confirmed on January 16 that it had given up to the Cosmology, Development and Research Commission of the Ministry of Education, Culture, Sports, Science and Technology for considering that the cost of repairing or remanufacturing the probe was too high. “Moon-A ” plan, but the committee still need to go through the discussion and assessment to decide whether to formally abandon the plan. “Moon-A ” plan as early as 1991 has been launched, the main content is the 1995 launch of the lunar probe “Moon-A ”. The Moon-A plans to carry two Penetrating Landers and launch them as they approach the Moon. The two 14cm diameter and 80cm long spears equipped with seismographs and thermal flowmeters, the observation device can penetrate the lunar surface of 1 to 3 meters, the moon’s internal structure, composition and thermal status, etc. Exploring. Although the detector was successfully developed in 1996, how to withstand the severe impact of landing on the lunar surface has not been resolved yet. After six deferrals, the development of the lander has been compromised. However, at this moment, the detector sleeping for more than 10 years in the warehouse has been seriously aged and can not be fired anymore.
