Future Meetings
February 7th
Speaker: Dr. Steve Desch professor of astrophysics in the School of Earth and Space Exploration at ASU (in person)
Speaker Bio:Steve Desch is a professor of astrophysics in the School of Earth and Space Exploration at ASU. His research focuses on developing models of star and planet formation, using data from meteoritics and planetary science. He especially studies the origins of chondrules and meteorites. He also works in the fields of exoplanets and astrobiology and is Principal Investigator (PI) of the NASA-funded NExSS grant to study geochemical cycles on exoplanets to aid searches for signs of life on other planets. He has modeled small icy bodies to explore the likelihood of subsurface water on Pluto and its moon, Charon, the asteroid Ceres, and others. He has recently advocated the concept of Arctic Ice Management, to study how to increase sea ice in the Arctic in response to climate change. Asteroid 9926 Desch is named after him.
Topic/Title: “Omuamua extra solar system object”
Talk summary:The first confirmed object from another star to visit our solar system, this interstellar interloper appears to be a rocky, cigar-shaped object with a somewhat reddish hue. The object, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated—perhaps 10 times as long as it is wide. That aspect ratio is greater than that of any asteroid or comet observed in our solar system to date. While its elongated shape is quite surprising, and unlike objects seen in our solar system, it may provide new clues into how other solar systems formed.
The observations suggest this unusual object had been wandering through the Milky Way, unattached to any star system, for hundreds of millions of years before its chance encounter with our star system.
“For decades we’ve theorized that such interstellar objects are out there, and now―for the first time―we have direct evidence they exist,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington, in November 2017.
March 7th
Speaker:Dr. David Williams – Research Professor School of Earth and Space Exploration Arizona State University (present or remote TBD)
Speaker Bio:Dr. David A. Williams is a Research Professor in the School of Earth and Space Exploration at Arizona State University, Tempe, Arizona. Dr. Williams is the Director of the Ronald Greeley Center for Planetary Studies, the NASA Regional Planetary Image Facility at ASU. He is also the Director of the NASA Planetary Aeolian Laboratory at the Ames Research Center in California. David is currently performing research in volcanology and planetary geology, with a focus on planetary mapping, geochemical, and remote sensing studies. Currently David is funded and devotes most of his time in the role of Co-Investigator and Deputy Imager Lead for the NASA Psyche mission.
Topic/Title: Psyche: Journey to a Metal World
Talk summary: The Psyche mission is a journey to a unique metal-rich asteroid orbiting the sun between Mars and Jupiter. What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system. Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets. The mission is led by Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for mission management, operations and navigation.
It should be noted that due to software development and testing issues the mission missed its 2022 launch date and is being scheduled for sometime in 2023.
April 4th
Speaker: Mark Johnston NASA Solar System Ambassador (in person)
Speaker Bio: Mark has been fascinated by the night sky ever since he ‘discovered’ Saturn in his 60mm Tasco refractor at age 11. 12 telescopes later, he is a NASA Solar System Ambassador, an award-winning astrophotographer and astronomy speaker. He is also a certified cruise ship lecturer on astronomy and space science topics and has earned a Master of Outreach from the Astronomical League as well as Volunteer of the Year from the mayor of Scottsdale for his public astronomy events there. He is an early pioneer with Night Vision and EAA outreach technologies and now specializes in providing live color imaging of galaxies and nebulae during his star party events.
Topic/Title: NASA Ambassador and other Recent Activities
Talk summary: Mark will speak on his experiences as a NASA Solar System Ambassador and Astronomy speaker and outreach presenter. He will also discuss his experience with Electronically Assisted Astronomy (EAA) and Night Vision enhanced astronomy.
