PICKERING LECTURE Rocketing to the Future: Space Electric Propulsion 19 August 2019 | JW Marriott, Indianapolis, Indiana OPEN TO THE PUBLIC One of NASA’s most remarkable interplanetary missions, the Dawn Eight deep-space exploration missions with electric propulsion spacecraft, used ion propulsion to orbit and explore the two have been launched and yet we have just scratched the surface largest uncharted worlds in the inner solar system, dwarf planet of what electric propulsion can do. Under development in 20 Ceres (2015–2018) and protoplanet Vesta (2011–2012). Dawn is countries around the world, electric propulsion will continue to the only spacecraft ever to orbit a body in the main asteroid see widespread use on commercial communication satellites belt, the only spacecraft to orbit a dwarf planet, and the only with likely prolific use in large constellations in low altitude spacecraft to orbit two extraterrestrial destinations. Dawn’s orbits. It will be used for exciting new deep-space robotic mission would have been impossible without its xenon-fueled ion science missions. Higher power versions are expected to benefit propulsion system, which ultimately provided a total effective all forms of planetary defense techniques, human missions to velocity change of 11.5 km/s (25,700 miles per hour) — comparable Mars, and asteroid mining, and advanced versions will ultimately to that provided by the entire three-stage Delta II launch enable rapid transportation throughout the solar system. vehicle that started the spacecraft on its deep-space journey. The Pickering Lecture will describe this extraordinary space Ion propulsion is a type of space electric propulsion, a technology propulsion technology and how Dawn and other missions take that has now been used on nearly 600 spacecraft. Over 40% advantage of it to accomplish amazing interplanetary adventures. of commercial geosynchronous satellites launched in recent years rely on the extraordinary capability of this technology. aiaa.org/PickeringLecture2019 SPEAKERS: JOHN BROPHY MARC RAYMAN Expert in Space Electric Dawn Mission Director, Propulsion, JPL Fellow JPL Chief Engineer for Operations and Science, JPL Fellow The William H. Pickering Lecture is named for the former NASA Jet Propulsion Laboratory Director, to honor his initiation and leadership of America’s unmanned scientific space program, from Explorer I in 1958 through the development of the Viking orbiters and the Voyager outer planet and interstellar missions. The lecture is open to all attendees and the general public.

As important as it is to look back at the moon landing 50 years ago in July [see of the European Space pages 20-35], we decided that the cover should air a possible solution to the greatest obstacle to Agency’s Heracles spacecraft arriving at the humans living and working in deep space. proposed lunar Gateway. Human biology cannot survive for very long outside of Earth’s protective magnetosphere. European Space Agency FHumans would be pummeled by deadly radiation if we tried to set up shop permanently on Mars or elsewhere in the solar system. Today, humanity doesn’t actually have the choice outlined by Jeff Bezos when he accepted the 2016 Collier Trophy on behalf of his company Blue Origin. “Either we stay here on Earth and have this civiliza- tion of stasis, or we expand into the solar system and have a dynamic, exciting civilization of exploration and pioneering,” Bezos said. Toying with our genes sounds like an outlandish way to expand into the solar system. But colonization sounds outlandish too, so maybe the answer needs to match. Of course, there could be other answers. If Earth can create a magnetosphere, perhaps humans can too. Or maybe the solution lies in materials and structures or in taking shelter in natural structures such as volcanic caverns. Whatever the answer, advocates of space colonization should make sure that humans can survive in deep space, less their ex- uberance draws more money than warranted to the fun stuff like deep space rovers, transports, mining tools and habitats.
