NASA找到消失8年的印度首艘月球太空船-欢迎您


本文摘要:US space agency NASA has successfully located Indias first lunar spacecraft Chandrayaan-1 that lost contact with ground controllers on Earth eight years ago.日前,美国航天局NASA早已顺利定位到印度首艘月球太空船--月球飞船一号,该飞船于8年前升空,但随后之后与地球上的地面掌控人员丧失了联系。

US space agency NASA has successfully located Indias first lunar spacecraft Chandrayaan-1 that lost contact with ground controllers on Earth eight years ago.日前,美国航天局NASA早已顺利定位到印度首艘月球太空船--月球飞船一号,该飞船于8年前升空,但随后之后与地球上的地面掌控人员丧失了联系。NASA found the spacecraft by using a new technological application of ground-based interplanetary radar and said its still circling some 200 kilometers above the lunar surface.NASA是通过陆基星际雷达的新技术找到了该宇宙飞船,相提并论它目前仍在月球表面海面200公里处飞过。This new technique also discovered an active spacecraft orbiting the moon, NASAs Lunar Reconnaissance Orbiter (LRO).这项新技术还找到了另一艘依然环绕月球运营的飞船,那乃是NASA的月球轨道探测器(LRO)。

LRO was launched on June 18, 2009, while Indias Chandrayaan-1 was launched on October 22, 2008.月球轨道探测器LRO号升空于2009年6月18日,而印度的月球飞船一号则升空于2008年10月22日。Finding LRO was relatively easy, as we were working with the missions navigators and had precise orbit data where it was located, Marina Brozovic, a radar scientist at NASAs Jet Propulsion Laboratory and principal investigator for the test project, said in a statement.美国宇航局喷气前进实验室及其测试项目的主要负责人玛丽娜·布洛祖维克在一份声明中回应:“相对来说,寻找LRO是较为更容易的。因为我们仍然与该任务的领航员一起工作并且有它方位的准确轨道数据。”Finding Indias Chandrayaan-1 required a bit more detective work because the last contact with the spacecraft was in August of 2009.“由于最后一次联络是在2009年8月,因此找寻印度的月球飞船一号就必须更好的侦查工作。

”More troubling was that the Chandrayaan-1 spacecraft is very small, about half the size of a smart car, and about 380,000 kilometers away.更加困难的是,月球飞船一号体积十分小,尺寸约为一辆智能汽车的一半,并且远在38万公里之外。To find the spacecraft, the team used NASAs 70-meter antenna at the agencys Goldstone Deep Space Communications Complex in California to send out a powerful beam of microwaves directed toward the moon.为了寻找它,该团队运用了坐落于加利福尼亚州的戈德斯合深层空间通信中心的70公尺口径天线,向月球收到强劲的微波束。NASA said these large radar antennas demonstrated that they can detect and track small spacecraft in lunar orbit.美国宇航局回应,这些大型雷达探测器证明,他们可以观测和追踪到小型的月球轨道探测器。Ground-based radars could possibly play a part in future robotic and human missions to the moon, both for a collisional hazard assessment tool and as a safety mechanism for spacecraft that encounter navigation or communication issues, the agency added.该机构补足道:“不管是作为撞击危险性评估工具,还是作为航天器遇上导航系统或通信问题的安全性机制,在未来的机器人和人类登月任务中,地面雷达都有可能会起着一定的起到。
