Michelle Lynde is an aerospace engineer who conducts aerodynamic analysis of configurations using Computational Fluid Dynamics tools, wind tunnel experiments and flight tests. Like other women at NASA, she makes history every day by contributing to groundbreaking missions and projects in the areas of space, science and aeronautics. Women at the agency are dedicated to inspiring the next generation of explorers to break new boundaries. Lynde’s work at NASA’s Langley Research Center in Hampton, Virginia, mainly focuses on aircraft design methods to improve aerodynamic performance. As an early-career professional, she’s already helped develop a new computationally-based design method to reshape aircraft wings to enable natural laminar flow technology on typical commercial aircraft. 米歇尔·林德(Michelle Lynde)是一名航空航天工程师，她使用计算流体动力学工具、风洞实验和飞行测试进行配置的空气动力学分析。和美国国家航空航天局的其他女性一样，她每天都在为太空、科学和航空领域的开创性任务和项目做出贡献，创造历史。该机构的女性致力于激励下一代探险家打破新的界限。 林德在美国国家航空航天局位于弗吉尼亚州汉普顿的兰利研究中心的工作主要集中在飞机设计方法上，以提高空气动力学性能。作为一名职业生涯早期的专业人士，她已经帮助开发了一种新的基于计算的设计方法，以重塑飞机机翼，使自然层流技术应用于典型的商用飞机。

Former astronaut Al Worden, command module pilot on the Apollo 15 lunar landing, passed away March 18, 2020, in Texas.​ As command module pilot, Worden stayed in orbit while commander David Scott and lunar module pilot Jim Irwin explored the Moon’s Hadley Rille and Appennine Mountains. Apollo 15’s command module, dubbed Endeavour, was the first to have its own module of scientific instruments. During the flight back from the Moon, Worden made three spacewalks to retrieve film from cameras in the module. Altogether, Worden logged more than 295 hours in space. In this image, Worden relaxes in the life raft while awaiting a helicopter pickup after the successful splashdown of the Apollo 15 spacecraft. Worden was born Feb. 7, 1932, in Jackson, Michigan. He was…

Michun North is a program analyst who helps manage finances for the Commercial Crew Program.​ Here’s what she has to say about her work: “I manage the finances for the Commercial Crew Program—which works with aerospace industry partners to develop and launch a new generation of spacecraft capable of carrying crew to low-Earth orbit and the International Space Station. I work with the program to understand how we are executing resources and help them budget for future requirements. I’m responsible for ensuring the contract is adequately funded. Knowing that the end game of this program is that we’re going to launch astronauts back to the International Space Station—that’s the ultimate motivation and what gets you in the door every day. Even though we aren’t part…

Apollo 9 launched in March 1969, and was the countdown to Apollo 11. Flown in low Earth orbit, it was the first flight of the full Apollo spacecraft: the command and service module with the lunar module. The mission was flown to qualify the lunar module for lunar orbit operations in preparation for the first Moon landing by demonstrating its descent and ascent propulsion systems. This would also demonstrate that its crew could fly it independently, then rendezvous and dock with the command module again, as would be required for Apollo 11. The three-person crew consisted of Commander James McDivitt, command module pilot David Scott, and lunar module pilot Russell Schweickart. In this image, McDivitt and Schweickart tested the lunar module in Earth orbit, while…
