Russia moon probe crash likely left 33-foot-wide crater on the lunar surface, NASA images show_我的网站

A |     周三公布的消息明显包含更多的商业企图。Waymo新任首席产品官Saswat Panigrahi表示，最初将有十几辆Waymo自动驾驶汽车进入洛杉矶，并在此基础上不断扩大规模，他最近担任战略、产品管理和数据科学副总裁。

B |     Russia's Luna-25 probe likely left a 33-foot-wide crater on the surface of the moon last month when it lost control and crashed down, NASA said Thursday, revealing images that show the suspected impact site.Russia's first moon mission in 47 years ended in failure on August 19 when the Luna-25 probe smashed into the moon after a thruster firing went awry, cutting off communications and putting the spacecraft on the wrong orbital path, according to Roscosmos, the Russian space agency.NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft captured images last week of what the U.S. space agency described as a "new crater" after Roscosmos published an estimate of where the probe had struck.

             

"Since this new crater is close to the Luna-25 estimated impact point," NASA wrote in a statement, "the LRO team concludes it is likely to be from that mission, rather than a natural impactor."      Moscow has set up a commission to investigate exactly why Luna-25 crashed.The failure was a major disappointment for the Russian space program, which was attempting to up its game amid renewed interest in the moon's southern polar region, where ice deposits may exist in permanently shadowed craters. Ice could offer future space missions a way to produce breathable air, water and even hydrogen rocket fuel.                 The Russians have had little success with independent space exploration since the Luna-24 robot landed on the moon in 1976. It scooped up about six ounces of lunar soil and returned it to Earth in Russia's third successful robotic lunar sample return mission.Twelve NASA astronauts walked on the moon a half century ago in the agency's Apollo program, but no Russian cosmonauts ever made the trip. Russia's only previous post-Soviet deep space robotic missions, both targeting Mars, ended in failure.

    

                                                     

    

Luna-25 was an attempt to pick up the torch and put Russia back into a new space race of sorts, as the U.S., China, India, Japan and the private sector all plan multiple moon missions that could lay the foundations for lunar bases and eventual flights to Mars.India's Chandrayaan-3 Vikram lunar lander made a historic touch-down near the moon's south pole just several days after the Russian probe crashed. It delivered a lunar rover that has already sent back data from soil samples.                      William Harwood contributed to this report.

。他补充说，其目的是将无人驾驶机器人出租车服务每天24小时运营。在其最终推出之前，Waymo正与当地团体MADD California和洛杉矶县自行车联盟合作。考虑让洛杉矶成为下一个试点城市有其原因，这个拥有1300万居民的大都市是美国第三大叫车市场，预计2022年将有20亿美元的机会，这也是Waymo有史以来试图推出的人口最多的市场。为了实现这一目标，Waymo还必须跳过一些监管障碍。两个监管机构，即加州公用事业委员会（CPUC）和加州机动车管理局（DMW）决定了自动驾驶汽车的测试和最终部署。加州车管所对有无安全操作人员的自动驾驶车辆的测试进行监管。如果公司想在没有人类操作员的情况下测试自动驾驶汽车，就必须获得无人驾驶测试许可证，在DMW审批的最后一步是向其签发部署许可。CPUC则负责签发"驾驶"和"无人驾驶"许可证，允许公司在他们的自动驾驶车辆中提供乘车服务，任何公司如果打算向乘客收费，就必须从DMV和CPUC获得所有这些许可。

C | Waymo已经从DMV获得了所有必要的许可，并从CPUC获得了为机器人出租车收费的许可，但前提是在乘车过程中有人类安全操作员在场。当它在加州等待这些最终许可时，该公司正在亚利桑那州运营并扩大规模。Waymo在钱德勒和凤凰城其他郊区运营着无人驾驶的商业出租服务。最近，该公司将其无人驾驶项目扩展到凤凰城市中心。
