Apr 9, 1999 · An asteroid has been named in honor of Jet Propulsion Laboratory scientist Dr. Chen-Wan L.Yen, developer of the ingenious flight path through space for NASA's Stardust comet sample return mission.

MESSENGER was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. [9][10] The name is a backronym for Mercury Surface, Space Environment, Geochemistry, and Ranging, and a reference to the messenger god Mercury from Roman mythology.

Mar 14, 2022 · In 1985, JPL orbital dynamics expert Chen-Wan Yen turned her attention to Mercury. She crunched the numbers for a range of launch windows and trajectories and demonstrated that it was possible to launch a spacecraft toward Mercury and, by doing multiple flybys of the planet combined with small propulsive maneuvers, put a relatively small ...

Chen-wan L. Yen received a PhD in Theoretical Physics from MIT in 1964. She has been with Jet Propulsion Laboratory for over 40 years designing many NASA solar system exploration missions such as Voyager, Cassini, MAGELLAN, Stardust, and MESSENGER and more.

Oct 16, 2002 · Chen-wan Yen, Stardust mission design manager at JPL, identified the opportunity for a flyby of Annefrank during the spacecraft's four-year cruise toward Wild 2. NASA approved the Annefrank test run this month, at no added cost.

Ask Chen-Wan Yen of the Jet Propulsion Laboratory (JPL) in Pasadena, California, the mission designer for the Stardust comet-sampling mission, what her primary criterion was in plotting a trajectory to get Stardust out to its comet and back home again, and her response is …

Jan 15, 2022 · During development of mission concepts, Chen-Wan Yen at JPL made an amazing discovery: with the type of trajectory and spacecraft needed for our mission, we could fly past a comet, collect...

Feb 20, 2024 · Fortunately, in 1985, Chen-Wan Yen, was a researcher at NASA’s Jet Propulsion Laboratory who studied orbital dynamics.

Oct 3, 2011 · Mercury had been neglected by robotic explorers partly because it is difficult to reach. The world had seen only fleeting visits from NASA's Mariner 10 spacecraft in the 1970s, and. before...
