猎户座的AA-2飞行测试品堆积如山!

猎户座的Ascent Abort-2飞行试验车从肯尼迪航天中心的发射中止系统设施向卡纳维拉尔角空军基地的空间发射综合体46推出，并于6月4日完成首次发射排练和飞行试验准备工作，为7月2日的发射做准备。在飞行过程中，猎户座的一个测试版本将使用一个助推器发射到超过6英里的高度，其中猎户座的发射中止系统（LAS）将安全地将太空舱拉离火箭。该团队将在接下来的几周内将所有AA-2元素堆叠在发射台上。该测试将证明，如果在太空发射系统火箭升空过程中发生紧急情况，猎户座的LAS可以使太空舱和未来的宇航员安全着陆。确保太空舱和未来宇航员的安全将为阿尔特弥斯在月球附近的任务铺平道路，使宇航员能够在2024年前登陆月球。 Orion’s Ascent Abort-2 flight test vehicle rolled out from Kennedy Space Center’s Launch Abort System Facility to Space Launch Complex 46 at Cape Canaveral Air Force Station and teams completed their first launch rehearsal, and flight test readiness review on June 4, in preparation for its planned July 2 launch. During the flight, a test version of Orion will launch on a booster to more than six miles in altitude where Orion’s launch abort system (LAS) will safely pull the capsule away from the rocket. The team will be stacking all the AA-2 elements together at the launch pad over the next few weeks. The test will demonstrate Orion’s LAS can steer the capsule and future crew to safety if an emergency occurs…

环绕声-猎户座阿尔特弥斯1号服务舱正在接受声学测试

上周，美国宇航局阿耳忒弥斯(Artemis)1号任务的服务舱在位于佛罗里达州的NASA肯尼迪航天中心的操作和校验大楼内完成了声学测试。此次测试是为NASA在太空发射系统(SLS)火箭上的猎户座无人飞行测试做准备的最新一步。 测试团队于2019年5月25日完成测试，技术人员将分析测试期间收集的数据，以检查声学环境发现的缺陷。在测试过程中，工程师将服务舱固定在测试单元内，然后将麦克风、应变仪和加速度计连接到服务舱上。他们进行了五项测试，声音水平从128分贝到140分贝不等，与飞机起飞时喷气发动机发出的声音一样大。 阿尔特弥斯1号将是SLS火箭在肯尼迪的39B发射台发射猎户座飞船的第一个任务。该任务将使猎户座飞船在月球数千英里外进行大约三周的试飞。猎户座将返回地球，并溅落在加利福尼亚海岸外的太平洋上，在那里它将被取回并返回肯尼迪航天中心。 Orion’s service module for NASA’s Artemis 1 mission completed acoustic testing inside the Operations and Checkout Building at NASA’s Kennedy Space Center in Florida last week. The tests were the latest step in preparing for the agency’s first uncrewed flight test of Orion on the Space Launch System (SLS) rocket. Teams completed the test May 25, 2019, and technicians will analyze the data collected during the tests to check for flaws uncovered by the acoustic environment. During the testing, engineers secured the service module inside the test cell and then attached microphones, strain gauges and accelerometers to it. They conducted a series of five tests, with acoustic levels ranging from 128 to 140 decibels – as loud as a jet engine during…
