Weekly Space Hangout

Jan 21, 2021

This week we are excited to welcome Dr. Aaron Rosengren and Di Wu to the Weekly Space Hangout. Their research team recently identified gravitational interactions which have produced a superhighway network of sorts within the Solar System. This network can reduce transport times for objects traveling between Jupiter and Neptune to decades rather than hundreds of thousands, or even millions, of years.

Long-term, this network may potentially be used for human exploration, but in the short-term, it could assist in the study of comets and asteroids.

Aaron J. Rosengren received his Ph.D. in Aerospace Engineering Sciences from the University of Colorado, Boulder in 2014. He served as a Marie Curie Postdoctoral Fellow for the European Union Asteroid and Space Debris Network, Stardust, from 2014 to 2016, at the Institute of Applied Physics Nello Carrara of the Italian National Research Council. In 2017, Dr. Rosengren worked at the Aristotle University of Thessaloniki in Greece in the Department of Physics, as part of the EU H2020 Project ReDSHIFT. He was an Assistant Professor at the University of Arizona (2017-2020) prior to his appointment at UC San Diego in July 2020. He received the "COSPAR Outstanding Paper Award for Young Scientists" on three separate occasions and has held invited visiting researcher positions in Australia, Israel, Italy, and Serbia.

Di Wu is a 3rd year PhD student of UC, San Diego. His research focuses on space situational awareness, astrodynamics, solar system dynamics, and machine learning. Recognized by the International Astronautical Federation, he was awarded the Future Space Leader for his research that bridges space debris characterization and asteroid dynamics. Di was also invited to attend the space generation congress and was involved in making policy suggestions to the UN about space sustainability.
