| 説明 | Caption: The image behind NASA technologist Jacob Englander shows the trajectory to Odysseus, a Trojan asteroid. Englander used his new orbit-determination tool to create the design (not associated with any mission or mission proposal) because a colleague suggested Odysseus was a difficult-to-reach target.Image Credit: NASA/Goddard/Pat IzzoTraveling to remote locations sometimes involves navigating through stop-and-go traffic, traversing long stretches of highway and maneuvering sharp turns and steep hills. The same can be said for guiding spacecraft to far-flung destinations in space. It isn’t always a straight shot.A NASA technologist has developed a fully automated tool that gives mission planners a preliminary set of detailed directions for efficiently steering a spacecraft to hard-to-reach interplanetary destinations, such as Mercury, Jupiter, Saturn, and most comets and asteroids.The tool, the Evolutionary Mission Trajectory Generator “offers a paradigm shift from what we normally do,” said Jacob Englander, a technologist at NASA’s Goddard Space Flight Center in Greenbelt, Md., who devised a concept for his computer-based tool while a doctorate student at the University of Illinois in Champaign. “EMTG will be used, and already is being used, to develop trajectories for proposed Goddard missions that cannot be designed using any other current tool.”Read more: 1.usa.gov/16EhP9mNASA image use policy.NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.Follow us on TwitterLike us on FacebookFind us on Instagram |
