奥森·约翰:一个NASA的通路学生变成了一个可靠性工程师

Orson John started his career at NASA as a summer intern, continued as a NASA Pathways student, and began a career at NASA’s Goddard Space Flight Center as an engineer after college. He earned a Bachelor of Science degree in physics in 2010 from the New Mexico Institute of Mining & Technology and now works as a reliability engineer in the Reliability & Risk Assessment Branch performing failure mode, fault and risk analyses for NASA spacecraft and instruments.

In this image, he is on the left and is preparing the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) for encapsulation in the United Launch Alliance Delta II payload fairing on Sept. 4, 2018, at Space Launch Complex 2 at Vandenberg Air Force Base in California. At the time, the satellite was being prepared for its scheduled launch on the final Delta II rocket. ICESat-2 measures the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. The satellite carried the Advanced Topographic Laser Altimeter System (ATLAS). ICESat-2 is helping scientists investigate why, and how much our planet’s frozen and icy areas, called the cryosphere, are changing in a warming climate.

奥森·约翰(Orson John)的职业生涯始于美国国家航空航天局(NASA)的暑期实习生，后来成为美国国家航空航天局通路(NASA Pathways)的学生，大学毕业后在美国国家航空航天局(NASA)戈达德太空飞行中心(Goddard Space Flight Center)的工程师。他在2010年获得了新墨西哥矿业与技术研究所的物理学学士学位，现在是可靠性与风险评估部门的可靠性工程师，为美国宇航局的航天器和仪器进行故障模式、故障和风险分析。

在这张图片中，他在左边，正在准备“冰、云和地面高度2号卫星”(ICESat-2)，准备于2018年9月4日在加州范登堡空军基地的航天发射场2号发射基地封装在联合发射联盟德尔塔2号有效载荷整理器中。当时，这颗卫星正在为最后一枚“德尔塔”(Delta II)火箭按计划发射做准备。ICESat-2测量不断变化的地球高度，一次一个激光脉冲，每秒10000个激光脉冲。卫星携带了先进的地形激光高度计系统(ATLAS)。ICESat-2正在帮助科学家调查为什么地球上的冰冻和冰冻区域，即冰冻圈，在变暖的气候中发生了多大的变化。
