SUMMARY:Online General Meeting – August 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n\n  \nThe Backstory of Contact Binary Stars\n\n  \n  \n \n\nContact binary star systems have the remarkable property that they orbit so closely they share a common atmosphere. They are the most common type of eclipsing binary star system. Despite extensive observations over more than a century\, answers to the most fundamental questions have eluded scientists until now: How do they form? How do they survive tranquilly in contact so long? What becomes of them in the end? An outburst in 2008 showed directly that contact binary stars end their long lives by merging in an explosive event known as a red nova. This presentation will reveal the recently uncovered backstory that answers these questions\, and it will conclude by considering how these answers might help identify which contact binary will be the next to explode. \n\n  \nProfessor Larry Molnar earned a B.S. in astronomy from the University of Michigan along with an MA and a PhD in astronomy from Harvard University. (Hence\, he has the three-degree background appropriate for one studying the Universe) He was a postdoc at the Smithsonian Astrophysical Observatory and taught at the University of Iowa. He has been a professor of Physics and Astronomy at Calvin University since 1998. \nViews: 72

SUMMARY:Online General Meeting – July 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n\n  \nRovers on Mars: 21st Century\n\n  \nNatural History\n\n  \nExpeditions to Another Planet\n  \n  \n \n\nPerseverance and Ingenuity are the current culmination of a long list of missions to Mars. During the first 400 days of operation on the surface of Mars Perseverance has traveled over 12 kilometers and Ingenuity has flown 28+ times. In addition to observations focused on understanding the geologic history and context of four+ samples collected for eventual return to Earth at this time\, Perseverance has made a variety of observations of the atmosphere and the moons of Mars. At the time of this presentation we will be well into the exploration of the enormous delta deposited by an ancient river onto the floor of Jezero Crater where Perseverance landed. \n\n\nLarry S. Crumpler\, Ph.D. is Research Curator in Volcanology and Space Sciences at the New Mexico Museum of Natural History and Science. He received his doctorate from the University of Arizona in Planetary Sciences and MS from the University of New Mexico in Geology. Prior to the Museum\, he worked at Brown University.   \nHe is a member of the Perseverance Rover Mission science team where he is responsible for geologic context mapping of the terrain traversed by the rover. Previously\, he was a team member on Ingenuity helicopter development\, Mars Exploration Rover (Spirit & Opportunity) where he served as “Long-term Planning Lead\,” Mars Odyssey Gamma Ray Spectrometer\, and Mars Reconnaissance Orbiter Camera (HiRISE).     \nHe previously participated in NASA’s Viking and Pathfinder Mars\, Magellan mission to Venus\, Russian Mars 96 mission planning\, Mars landing site selection and rover field tests.   He has published numerous research papers\, book chapters\, and geologic maps; and a book about Mars that will be published by Harper-Collins in late 2021.  He is a Fellow of the Geological Society of America. \nViews: 72

SUMMARY:Online General Meeting – June 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n\n  \n  \nThree Decades of\n  \n  \nthe Hubble Space Telescope\n\n  \n\n \n\nAfter decades of discussion and construction\, the Hubble Space Telescope was finally launched on April 24\, 1990. While HST was not the first space telescope\, it represented a major expansion in capability that has helped upend humanity’s understanding of the universe. HST helped show that the expansion of the universe is accelerating\, and has transformed our view of the universe with a remarkable set of Hubble Deep Field images\, amongst other things. Along the way\, the engineers\, scientists and astronauts behind HST managed to overcome a debilitating optical problem and have kept HST making discoveries for more than three decades. Now HST is about to work in tandem with its successor\, the James Webb Telescope.\nNot Yet Imagined E-flyer\n\n \n\n \n\nChristopher Gainor is a historian of technology specializing in space exploration and aeronautics. He has written four books on the history of space exploration and two on Cold War history. His most recent book is a history of Hubble Space Telescope operations published by NASA. Gainor is editor of Quest: The History of Spaceflight Quarterly. From 2018 to 2020\, he was President of the Royal Astronomical Society of Canada\, and he is a fellow of the British Interplanetary Society. Gainor holds a Ph.D. in the history of technology from the University of Alberta\, and has worked as a history instructor at the University of Victoria and the Royal Military College of Canada.\n\n \nhttps://chrisgainor.ca\n \nhttps://www.facebook.com/Gainorbooks\n \nhttps://twitter.com/chrisgainor\nViews: 72

SUMMARY:Online General Meeting - May 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \n\nOumuamua: The nearest exoplanet?\n\n  \n  \n\n \n\n\n\n\n\n\nWhen ‘Oumuamua passed by Earth in October 2017\, the only thing certain about it was that it was not from this Solar System. Because of its high velocity\, it was the first confirmed interstellar object. The next year the object 2I/Borisov was the second confirmed interstellar object. But whereas Borisov behaved very much like a comet (albeit an unusual one)\, mysteries remain about what ‘Oumuamua actually is. Although it pushed away from the Sun by a rocket effect\, like comets\, it could not be made of water\, or contain much carbon monoxide or dust\, making it very unlike a comet. The acceleration it experienced was very large\, and from the variations in sunlight it reflected\, it was more elongated than any other solar system object: either a very skinny pancake or a very long cigar. Dozens of explanations have been proposed to explain these oddities\, and speculation has run rampant\, with some astronomers even suggesting it was alien technology. The truth is more mundane but no less exciting. In a pair of papers in 2021\, Steve Desch and Alan Jackson demonstrated that ‘Oumuamua is consistent in every way with being a small fragment resembling the surface of Pluto. Our own solar system must have ejected trillions of fragments like ‘Oumuamua in its early days\, and a population of fragments from the surfaces of Pluto-like exoplanets must be common throughout the Galaxy. ‘Oumuamua itself may have been ejected about 400 million years ago\, from a Pluto-like exoplanet in a young system in the Perseus arm of the Galaxy. ‘Oumuamua is arguably the closest we’ve ever come to directly observing the surface of an exoplanet.\n\n\n\n\n\n\n\n\nSteve Desch is a Professor of astrophysics in the School of Earth and Space Exploration at Arizona State University. He studies the formation and evolution of planets\, the origins of the Solar System\, exoplanets\, and meteorites. He has written about ‘Oumuamua in the popular press and is thrilled to have contributed to our scientific understanding of this unique object.” \n\n\nhttps://slate.com/technology/2019/01/oumuamua-alien-ship-anthropomorphize-space.html\n\n\nViews: 72

SUMMARY:Online General Meeting - April 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \n\nThe End of the Beginning\n  \n\n\n\n\n\nWe used to think the Big Bang meant the universe began from a singularity. Nearly 100 years later\, we’re not so sure. The Big Bang teaches us that our expanding\, cooling universe used to be younger\, denser\, and hotter in the past. However\, extrapolating all the way back to a singularity leads to predictions that disagree with what we observe. Instead\, cosmic inflation preceded and set up the Big Bang\, changing our cosmic origin story forever.\n\nDownload PDF of the presentation\n\n\n\n\n\n\n\nEthan has lived his life fascinated with one simple fact: we have the capacity to figure out definitive\, scientific answers to even the deepest questions we can conceive about our physical reality. We do that by asking the right questions about the Universe\, and then putting the Universe itself to the test. From where everything comes from to the Universe’s ultimate fate and all that lies between\, he’s committed to not just figuring it out\, but to sharing the answers — what we know and how we know it — with anyone curious enough to listen.\n\n\nhttps://www.startswithabang.com/\n\n\nhttps://twitter.com/StartsWithABang\nhttps://www.facebook.com/startswithabang\n\nViews: 72

SUMMARY:Online General Meeting - March 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \n\nBringing Astronomy Alive:\n\n\n  \n\nStudent Engagement at\n\n\n  \n\n\nJohn Abbott College\n  \n\n\n\n\n\n\n\nThe non-traditional approach to Introductory Astronomy at John Abbott College (Montreal\, Canada) puts the depth and direction of content in the hands of the students\, utilizing partnerships with RASC Montreal Centre and other Outreach Organizations to mentor students in observational techniques\, provide access to amateur and professional Astronomical data\, and introduce students to public outreach.\n\n\n\nRecognizing the available access to recent discoveries and current data that best represent the direction of space sciences\, each student is given an opportunity to put their stamp on the learning outcomes of the course. Combining this with non-compulsory astronomy activities with RASC – Montreal Centre allows students to embrace the field in a manner that best suits their interests and motivation\, resulting in novel labs and incredibly diverse term projects\, and several initiatives that have moved beyond the scope of the Introductory Astronomy Course. Other departments and courses at the college are now taking advantage of the Astronomy activities to engage their students beyond the classroom.\n\n\n\n\n\n\nProf. Karim Jaffer joined the Physics Faculty at John Abbott College (JAC) in 2006\, with active projects in STEM education and pedagogical development. When Karim began teaching Introductory Astronomy in 2016 he developed a unique student-directed\, just-in-time teaching approach incorporating current astronomical data\, research\, and including experiential learning opportunities.\n\n\n\n\n\n\n\nIn the amateur astronomy community Karim has been the Public Events Coordinator for the RASC Montreal Centre since 2016\, helping re-establish the I.K.Williamson Astronomy Library and coordinating both public events and outreach activities throughout the Montreal area\, cultivating partnerships with the Rio Tinto Alcan Planetarium\, the Institute for Research on Exoplanets (iREx)\, the Cosmodome\, Explore Alliance\, the Astronomical League\, AstroRadio\, CASCA and many local amateur astronomy groups\, in addition to mentoring several Student Astronomy clubs and coordinating visits to local schools\, guides\, scouts and libraries.\n\n\n\n\n\n\n\nKarim is a member of the National RASC Education and Public Outreach Committee and the 2021 recipient of the Charles M Good Award.\n\n\n\n\n\n\n\n\nwww.rascmontreal.org/titan\n\n\n\n\n\n\nViews: 72

SUMMARY:Online General Meeting - February 2022
DESCRIPTION:This is a free and open to the public online event. \nJoin Zoom\n  \nDragonfly: Exploring an Organic Rich Moon\n  \n \nTitan is the only moon in our solar system with a dense atmosphere\, which supports an Earth-like hydrological cycle of methane clouds\, rain\, lakes\, and seas. Complex organic surface materials may preserve\, in a deep freeze\, the types of organic chemicals that would have been present on Earth before life developed. Titan’s icy crust floats atop an interior liquid water ocean. The Dragonfly mission to Titan will characterize its habitability and determine how far prebiotic chemistry has progressed in environments known to provide the necessary ingredients for life. The mission comprises a single rotorcraft lander with a sophisticated scientific payload\, designed to take advantage of Titan’s environment\, and achieve wide-ranging exploration by flying to sites in different geologic settings. \n \nDr. Melissa Trainer\nDr. Melissa Trainer is a planetary scientist at NASA’s Goddard Space Flight Center (GSFC) with expertise in the composition of planetary atmospheres and the production of organic molecules and aerosols via in situ synthesis pathways. She has spent more than a decade characterizing the properties of Titan and early Earth aerosol analogs\, with publications on the chemical\, optical\, and isotopic properties of organic hazes. Dr. Trainer is a member of the Mars Science Laboratory Sample Analysis at Mars (SAM) instrument team\, for which she led the campaign to conduct the first in situ multi-year study of the seasonal variations of the composition of the Mars atmosphere through surface mass spectrometry measurements. Dr. Trainer currently serves as a Deputy Principal Investigator (PI) for the Dragonfly mission to Saturn’s moon Titan\, part of the NASA Planetary Science New Frontiers Program. She is also the lead for the Dragonfly Mass Spectrometer (DraMS)\, which enables the investigation of Titan’s surface composition and characterization of potential prebiotic chemistry. \nhttps://dragonfly.jhuapl.edu/ \nhttps://science.gsfc.nasa.gov/solarsystem/ \n  \n  \nViews: 72

SUMMARY:Online General Meeting - January 2022
DESCRIPTION:This is a free and open to the public online event\, to attend please register with zoom by clicking here. \nPsyche: Journey to a Metal World\n  \n  \n \nNASA selected Psyche as the 14th Discovery mission on Jan. 4\, 2017. Led by Arizona State University\, Psyche will be the first orbiter of a M-class asteroid\, (16) Psyche. The mission design is based on NASA’s Dawn mission at Vesta & Ceres\, and uses instruments with a strong heritage from past missions. Our science objectives are to answer the following questions: 1) Is Psyche an exposed planetary core\, or did it never undergo melting? 2) What are the relative ages of features on its surface? 3) Do small metal-rich bodies incorporate light elements expected to be inside Earth’s high-pressure core? 4) Did Psyche form under more oxidizing or more reducing conditions than Earth’s core? and 5) What is the topography of this metal world? Psyche will launch in Aug. 2022 and will enter orbit of (16) Psyche in Jan. 2026 for a 21-month nominal mission. Psyche will study the surface using a pair of multispectral imagers (clear filter & 7 color filters\, for surface morphology\, stereo topography\, and detection of certain key mineral classes)\, a gamma-ray & neutron spectrometer (for elemental abundances)\, and dual fluxgate magnetometers (to search for a remanent magnetic field). A gravity investigation using tracking of the spacecraft’s radio signal is also planned. Psyche will characterize surficial geologic features\, topography\, and compositions through four consecutively lower orbital phases\, each optimized to obtain data to accomplish our science objectives. Psyche will: 1) map ≥80% of the surface with long-l filters at ≤500m/pix (assess metal to silicate fraction)\, 2) map ≥80% of the surface with short-l filters at ≤200m/pix (spectral detection of oldhamite\, (Ca\,Mg)S)\, 3) map ≥50% of the surface with clear filter at ≤200m/pix (crater counting)\, 4) map ≥80% of the surface with clear filter at ≤20m/pix (geologic mapping)\, and 5) determine the shape of (16) Psyche by mapping with clear filter over ≥80% of its surface with ≤200m/pix using stereo imaging techniques. This presentation discusses details of our mission. \n \nDr. 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\, a NASA-supported planetary data center at ASU. He is also the Director of the NASA Planetary Aeolian Laboratory\, which administers wind tunnels 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. His current research focusses on planetary geologic mapping of bodies across the Solar System\, and computer modeling of the physical and geochemical evolution of lava flows in a variety of planetary environments. He was involved with NASA’s Magellan Mission to Venus\, Galileo Mission to Jupiter\, Dawn Mission to asteroid Vesta and dwarf planet Ceres\, and ESA’s Mars Express orbiter mission.  He is a member of the Janus camera team for the ESA JUICE mission\, and he is currently Deputy Imager Lead and a Co-Investigator on NASA’s Psyche Mission\, scheduled to launch in August 2022.  In 2014 David was elected a Fellow of the Geological Society of America\, and asteroid 10\,461 DAWILLIAMS was named in his honor. \n  \nASU Psyche Mission:  https://psyche.asu.edu/ \nJPL Psyche Mission:  https://www.jpl.nasa.gov/missions/psyche \nWebsite:  https://rgcps.asu.edu/dawilliams/ \nFacebook:  https://www.facebook.com/profile.php?id=10023395 \nTwitter:  @davidaw222 \nInstagram:  @davidaw222 \nViews: 72

SUMMARY:Online General Meeting - December 2021
DESCRIPTION:This is a free and open to the public online event\, to attend please register with zoom by clicking here. \n  \n\nAn Antarctic Odyssey: Winter-Over at South Pole Station\n\n \n\n  \nIn a lavishly illustrated presentation\, John W. Briggs of New Mexico will describe his year-long experience living at the Geographic South Pole while working for the Center for Astrophysical Research in Antarctica.  In preparation for this at Yerkes Observatory of the University of Chicago\, John was a team member building a 24-inch infrared telescope and related experiments that were set up at the Pole in time for him and colleagues to observe the July\, 1994\, explosive crash of fragmented comet Shoemaker-Levy 9 into the planet Jupiter. \nJohn weathered the “winter-over” with 26 other members of the U.S. Antarctic Program in an experience that many believe approximates what life will be like someday at a lunar or Martian outpost.  Once begun\, South Pole winter-over is an irreversible commitment\, since the Program’s special LC-130 ski planes can’t land in the winter temperatures — in 1994\, sometimes as low as 107 degrees F. below zero (with windchill\, as low as -180 degrees).  John will delight the audience with his perspective on the total South Pole experience — the strange natural environment\, the odd social atmosphere\, and the challenging\, ongoing science. \n  \n\n \nJohn W. Briggs has lived and worked at far-ranging observatories in various technical capacities\, including Mount Wilson\, Yerkes\, National Solar\, Maria Mitchell\, Venezuelan National\, Chamberlin\, and South Pole Station.  He came to New Mexico with his family in 1997 to assist in the final commissioning of the Sloan Digital Sky Survey at Apache Point.  In the 1980s he was an assistant editor at Sky & Telescope magazine and built Bogsucker Observatory in Massachusetts.  He is a member of many astronomical organizations including the Springfield Telescope Makers responsible for the annual Stellafane Convention in Vermont\, and he has recently been elected to the board of the century-old American Association of Variable Star Observers.  His principal activity now involves the Astronomical Lyceum\, an informal museum\, library\, laboratory\, and lecture hall devoted to historical astronomy and its preservation\, located in a 1936 former school gymnasium-theater in Magdalena\, New Mexico.  In the middle 1980s he assisted the late Professor Edgar Everhart\, Director of Chamberlin Observatory\, in his well-known program of cometary astrometry.  John has many old friends in the Denver Astronomical Society.\nViews: 72
