Weekly Space Hangout - Solar System Superhighways with Dr. Aaron Rosengren & Di Wu 01/22/2021

Weekly Space Hangout - Solar System Superhighways with Dr. Aaron Rosengren & Di Wu Host: Fraser Cain ( )Special Guest: This week we are excited to welcome Dr. Aaron Rosengren and Di Wu (with Dr. Nataša Todorović in the chat), 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. Dr. 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. You can read the team's paper, The Arches of Chaos in the Solar System, on the AAAS site: You can learn more about the team's research on the ScienceAlert website: Regular Guests: Dr. Morgan Rehnberg ( & ) Allen Versfeld ( & ) This week's stories: - What happened with the SLS Green Run? - Calculating the digital color codes of stars. - NASA gives up on Insight. JAXA = YOLO! - Alternative propulsions systems are being tested with cubists. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Weekly Space Hangout - Dr. Alan Stern: What’s On The Horizon For New Horizons 01/08/2021

Weekly Space Hangout - Dr. Alan Stern: What’s On The Horizon For New Horizons Host: Fraser Cain ( )Special Guest: This week we are excited to welcome Dr. Alan Stern, Principal Investigator from the New Horizons Mission, back to the WSH. In October, it was announced that Alan will be the first NASA-funded commercial space crewmember aboard a Virgin Galactic suborbital space mission. The flight is expected to take place in 2022; there he will perform astronomical and space physiology experiments. Alan is a planetary scientist, space program executive, aerospace consultant, and author. He leads NASA’s New Horizons mission to the Pluto system and the Kuiper Belt. In both 2007 and 2016, he was named to the Time 100. In 2007, he was appointed NASA’s chief of all science missions. Since 2009, he has been an Associate Vice President and Special Assistant to the President at the Southwest Research Institute. Additionally, from 2008-2012 he served on the board of directors of the Challenger Center for Space Science Education, and as the Chief Scientist and Mission Architect for Moon Express from 2010-2013. From 2011- 2013, he served as the Director of the Florida Space Institute. Alan's career has taken him to numerous astronomical observatories, to the South Pole, and to the upper atmosphere aboard various high performance NASA aircraft including F/A-18 Hornets, F-104 Starfighters, KC-135 Zero-G, and WB-57 Canberras. He has been involved as a researcher in 24 suborbital, orbital, and planetary space missions, including 9 for which he was the mission principle investigator; and he has led the development of 8 scientific instruments for NASA space missions. In 1995, he was selected as a space shuttle mission specialist finalist, and in 1996 he was a candidate space shuttle payload specialist. In 2010, he became a suborbital payload specialist trainee, and is expected to fly several space missions aboard XCOR and Virgin Galactic vehicles in 2016-2017. Before receiving his doctorate from the University of Colorado in 1989, Alan completed twin master's degrees in aerospace engineering and atmospheric sciences (1980 and 1981), and then spent six years as an aerospace systems engineer, concentrating on spacecraft and payload systems at the NASA Johnson Space Center, Martin Marietta Aerospace, and the Laboratory for Atmospheric and Space Physics at the University of Colorado. His two undergraduate degrees are in physics and astronomy from the University of Texas (1978 and 1980). His academic research has focused on studies of our solar system's Kuiper Belt and Oort cloud, comets, the satellites of the outer planets, the Pluto system, and the search for evidence of solar systems around other stars. He has also worked on spacecraft rendezvous theory, terrestrial polar mesospheric clouds, galactic astrophysics, and studies of tenuous satellite atmospheres, including the atmosphere of the moon. Alan is a fellow of the AAAS, the Royal Astronomical Society, and is a member of the AIAA, AAS, IAF, and the AGU; he was elected incoming chair of the Division of Planetary Sciences in 2006. He has been awarded the Von Braun Aerospace Achievement Award of the National Space Society, the 2007 University of Colorado George Norlin Distinguished Alumnus Award, the 2009 St. Mark’s Preparatory School Distinguished Alumnus Award, Smithsonian Magazine’s 2015 American Ingenuity Award, and the 2016 Sagan Memorial Award of the American Astronautical Society. In his free time, Alan enjoys running, hiking, camping, and writing. He is an instrument-rated commercial pilot and flight instructor, with both powered and sailplane ratings. He and his wife Carole have two daughters and a son; they make their home near Boulder, Colorado.
