30. OSIRIS-REx Asteroid “Smash & Grab” – Mission Update
11/14/20 • 20 min
Phone Interview with OSIRIS-REx Project Scientist Dr. Jason P. Dworkin
On October 20th, 2020, NASA’s OSIRIS-REx spacecraft made history as it collected samples from asteroid Bennu, which are expected to return to Earth in 2023. For this episode I’m pleased to introduce Dr. Jason Dworkin, the project scientist for OSIRIS-REx, for an update and more details on the OSIRIS-REx mission.
About OSIRIS-REx
(Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer)
https://www.asteroidmission.org/
OSIRIS-REx seeks answers to the questions that are central to the human experience: Where did we come from? What is our destiny? Asteroids, the leftover debris from the solar system formation process, can answer these questions and teach us about the history of the sun and planets.
The OSIRIS-REx spacecraft is currently orbiting Bennu, a carbonaceous asteroid whose regolith may record the earliest history of our solar system. Bennu may contain the molecular precursors to the origin of life and the Earth’s oceans. Bennu is also one of the most potentially hazardous asteroids, as it has a relatively high probability of impacting the Earth late in the 22nd century. OSIRIS-REx will determine Bennu’s physical and chemical properties, which will be critical to know in the event of an impact mitigation mission. Finally, asteroids like Bennu contain natural resources such as water, organics, and precious metals. In the future, these asteroids may one day fuel the exploration of the solar system by robotic and crewed spacecraft.
About Dr. Jason Dworkin
https://science.gsfc.nasa.gov/sed/bio/jason.p.dworkin
Jason Dworkin is the Project Scientist for OSIRIS-REx and NASA's Senior Scientist for Astrobiology. Jason's objective is to assess the organic species available for the origin and early evolution of life with a focus is on understanding the extraterrestrial input and origin of molecules relevant for life. This objective has been to study increasingly documented and constrained systems, from plausibly early Earth chemistry, chemistry of astrophysically relevant laboratory ices, organic and chiral analysis of meteorites, to analysis of sample returned material and how to protect that material from contamination. This research employs modern analytical methods to examine authentic samples of the early solar system as well as laboratory models of ancient environments. This involves both directing research in the Astrobiology Analytical Laboratory at NASA Goddard Space Flight Center (GSFC) and scientific leadership in NASA sample return and in situ missions.

29. Water Discovered on Sunlit Surface of the Moon – Lunar Geologist Sarah Noble
NASA’s aircraft SOFIA (Stratospheric Observatory for Infrared Astronomy) has confirmed for the first time, water on the sunlit surface of the Moon. Previously NASA had discovered evidence for water in shadows of craters, but this new discovery has incredible implications for possible use of this water as a resource as NASA returns to the Moon. Lunar Geologist Dr. Sarah Noble joins us today to discuss this incredible discovery and its implications for the future of space exploration, especially with NASA’s plan to send the first woman and next man on the Moon in 2024.
In this interview Sarah discusses how SOFIA made this discovery, how much water was found, and future plans for investigating on the Moon, including NASA's VIPER rover, a mobile robot that will go to the South Pole of the Moon to get a close-up view of the location and concentration of water ice.
About Sarah Noble (from NASA.gov)
Sarah Noble grew up in rural Minnesota, where from a very young age she was fascinated with space exploration, staring up at the moon and making plans to visit it one day. She started collage as an aerospace engineering major, because it was the only major with the word “space” in it, but stumbled into a geology class one day and fell in love with the science. Knowing her love of all things space related, her professors steered her towards planetary geology, the subfield of geology that studies how other planets (and moons and asteroids and comets and whatnot) form, evolve, and operate. She started her NASA career studying meteorites as an undergraduate intern at NASA’s Johnson Space Center in Houston. After graduate school, and a short adventure working for Congress, she returned to Johnson, and also spent time working at NASA’s Marshall Space Flight Center in Alabama and Goddard Space Flight Center in Maryland before finding her place at the agency’s headquarters in Washington. She has worked as a program officer and discipline scientist in the Planetary Science Division at NASA Headquarters since 2010 working on missions, as well as research and analysis programs. She is an avid painter and is passionate about sharing the joy and beauty of space exploration, both through science outreach and through her artwork.

31. Planetary Scientist Alan Stern Heading to Space Aboard Virgin Galactic
Planetary scientist Dr. Alan Stern has been chosen to be the first to conduct NASA-funded science experiments while flying aboard a commercial spacecraft. In this interview Dr. Stern discusses the experiments he will perform aboard Virgin Galactic’s “SpaceShipTwo” on a suborbital mission from the Spaceport America launch site in New Mexico. He also discusses software upgrades coming to the New Horizons spacecraft in 2021, and as a proponent of Pluto, explains why it should be considered the ninth planet in our solar system.
About Dr. Alan Stern
Dr. Alan Stern is a planetary scientist, space program executive, aerospace consultant, author, and avid public speaker. Since 2001 he has led NASA’s $880M New Horizons mission that successfully explored the Pluto system and is now exploring the Kuiper Belt—the farthest exploration in the history of humankind. In 2018, he was named by the Administration to a six yearlong term to the U.S. National Science Board. In both 2007 and 2016, he was named to the Time 100 list. In 2020, NASA selected Dr. Stern to fly as an experimenter on a commercial suborbital spaceflight aboard Virgin Galactic’s SpaceShip2.
Since 2009, Dr. Stern 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. Dr. Stern serves as the Chief Science Officer of World View, a near-space ballooning company that he is co-founder of. In 2016 and again in 2017 he was elected to be the Board Chairman of the Commercial Spaceflight Federation. Dr. Stern is also on the advisory board of Lowell Observatory.
Dr. Stern also maintains his own aerospace consulting practice. His current and former consulting clients include Jeff Bezos’s Blue Origin, Richard Branson’s Virgin Galactic, Naveen Jain’s Moon Express Google Lunar X-Prize team, Ball Aerospace, Paragon Space Development Corporation, the NASTAR Center, Embry Riddle Aeronautical University, and the Johns Hopkins University.
His 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 29 suborbital, orbital, and planetary space missions, including 14 for which he was a 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 suborbital space missions aboard Virgin Galactic vehicles in 2019-2020.
