SUMMARY:General Meeting – November 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from San Jose\, CA.\n  \nFrom Vision to Reality:\n  \nThe Journey of Kosovo’s First Observatory\n  \n\n\n  \nIn 2024\, we successfully established the first observatory and science center in Kosovo\, a landmark achievement in a country with a rich but turbulent history. This project was not just about building an astronomical facility; it symbolized triumph over obstacles that ranged from logistical challenges to securing international support. Through perseverance\, partnerships with organizations like Celestron\, and the belief in the transformative power of science\, we brought the stars closer to the people of Kosovo. This talk will highlight our journey\, the hurdles we overcame\, and how this observatory is now inspiring future generations of scientists and stargazers alike. \n  \nPranvera Hyseni is a graduate student from the Republic of Kosovo\, currently pursuing a Ph.D. in Earth and Planetary Science at the University of California\, Santa Cruz. She is the founder of Astronomy Outreach of Kosovo (AOK)\, which is recognized as the largest astronomy outreach program in Eastern Europe. Additionally\, she manages the Kosovo Chapter of the Charlie Bates Solar Astronomy Project. \nMs. Hyseni’s interest in astronomy began at an early age of three\, during the late 1990s when Kosovo was affected by the Serbian conflict. She was raised in a family of eight on a remote farm\, where economic conditions were challenging. Despite these circumstances\, the farm’s location provided her with access to clear night skies\, igniting her early passion for astronomy. \nShe single-handedly brought science to her community by establishing the non-profit organization “Astronomy Outreach of Kosovo” in 2015\, which has grown into a significant entity with a global network of professional and amateur astronomers supporting her outreach initiatives across Kosovo. Through these extensive outreach activities\, AOK has had a substantial impact\, reaching and engaging with over 25\,000 individuals annually. Her extraordinary commitment has earned her recognition as one of the five most influential women in Kosovo. \nHer impact extended beyond AOK through collaborations with the Ministry of Education\, Science\, and Technology of Kosovo\, as well as other governmental institutions. Highly regarded for her expertise\, she is in high demand as a speaker at universities and international astronomy conferences worldwide. In 2022\, she made history by establishing the first International Astronomy and Planetary Sciences Convention in Kosovo\, featuring esteemed astronomers and scientists. \nCurrently based in San Jose\, California\, Pranvera Hyseni’s research focuses on understanding the formation histories of asteroids\, comets\, and meteorites through spectroscopy analysis. In 2017\, her contributions to the field received recognition from the International Astronomical Union and the Minor Planet Center\, resulting in the naming of an asteroid in her name\, 45687 Pranverahyseni. The Mars Generation organization honored her with the “24Under24” award for her leadership in STEM education. She received the “Master Outreach Award” from the Astronomical League in 2019 and the “Michael Reynolds Astronomy Award” from the Association of Lunar & Planetary Observers in 2020. \nPranvera Hyseni’s research achievements extend to her provisional discovery of a Main Belt asteroid\, 2020 SS13\, utilizing data provided by Pan-STARRS in collaboration with the International Asteroid Search Collaboration. Her research endeavors received financial support with an amount of $5\,000 through the “Casey J. Moore Fund Award” from her department at UC Santa Cruz. \nBeyond her academic pursuits\, Ms. Hyseni is the founder of Kosovo’s first observatory and planetarium. She envisions this science center as a crucial resource accessible to the public\, furthering science and technology education. The facility accommodates a Celestron C14 Edge HD telescope with a CGX-L equatorial mount generously donated by Corey Lee\, the CEO of Celestron – making it the largest telescope in the entire Republic of Kosovo. \nPranvera Hyseni’s unwavering dedication to advancing science education\, outreach\, and astronomical research marks her as a notable figure in the scientific community\, leaving an enduring impact on generations to come. As a testament to her profound impact\, she proudly serves as an Official Brand Ambassador for Celestron\, inspiring countless individuals with the wonders of the universe. \nViews: 5

SUMMARY:General Meeting – October 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present inperson from the Chapman University’s campus.\n\n  \n  \nDirect Multipixel Imaging and\n  \nSpectroscopy of Exoplanets\n  \nwith a Mission to the Focal Region of\n  \nthe Solar Gravitational Lens\n  \n \n  \nNature has presented us with a very powerful “instrument” that we are yet to explore and put to use. This instrument is the Solar Gravitational Lens (SGL)\, which results from the ability of the gravitational field of the Sun to focus light from faint\, distant targets. In the near future\, a modest telescope with a coronagraph could operate in the focal region of the SGL and\, using enormous amplification of the Lens\, it could yield multipixel images of exoplanets.  A meter-class telescope operating at the focal region of the SGL could yield ~(450×450)-pixel images of an “Earth 2.0” at distances up to 100 light years with spatial resolution high enough to see its surface features and to determine and study the signs of habitability. We discuss the imaging properties of the SGL and introduce a mission concept to the SGL focal region that could provide us with direct\, high-resolution images and spectroscopy of a potentially habitable Earth-like exoplanet. We address aspects of mission design and spacecraft requirements\, as well as capabilities needed to fly this mission in the next two decades. We rely on solar sailing propulsion which\, when combined with rideshare to high Earth orbit and the use of smallsat architecture components\, is the key technology that may allow us to reach high solar system transit velocities at a dramatic reduction in mission costs and lead time. With the currently available sail materials\, components\, and instruments we can fly practical missions with speeds of up to 7 AU/year – twice that of the current speed record holder – Voyager 1.  With the sail materials that are being developed\, smallsat velocities up to 20-25 AU/year will be reachable in 5-7 years. Benefiting from this progress\, the “Sundiver” concept is new and exciting; it offers breakthrough capabilities for which the science community has been waiting for decades. We discuss the Sundiver sailcraft\, enabling technology\, instruments and unique science opportunities offered by small sailcraft placed on fast interplanetary trajectories – ultimately reaching the SGL’s focal region. \nFor background\, please check: https://www.youtube.com/watch?v=NQFqDKRAROI and https://arxiv.org/abs/2303.14917 \n  \n \n  \nSlava G.

SUMMARY:General Meeting – September 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that people under 18 are not allowed at Chapman campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from China.\n  \nWhat is the role fungi\n  \n in space exploration?\n  \n \n  \nThe field of space exploration is currently witnessing great developments and increased attention. As we gear up for new missions\, we need to think about the tiny “hitchhikers” we bring along—microbes that come with us\, either as part of our microbiomes or as chosen resources. Just like us\, these microbes are affected by space conditions. So\, understanding how they grow in space is crucial for planning future safe and sustainable missions. \nIn space microbiology\, fungi often don’t get the attention they deserve. They can be a threat to astronauts\, especially under stressful conditions like altered gravity\, radiation\, and exposure to lunar and Martian soil\, where\, for example\, they can develop pathogenicity. However\, fungi can also be incredibly useful. They can produce important products like medical drugs\, metal nanoparticles\, and enzymes. In space\, fungal processes can change and sometimes improve\, leading to cheaper and more efficient production processes. \nThis presentation will explore how fungi can help us in future missions and the risks they pose\, such as infections\, contamination\, or damage to infrastructure. Research in astromycology\, which studies terrestrial fungi in space and space-like environments\, will be key to supporting sustainable\, long-term human presence in space. \n \nMarta Filipa Simões (ORCID ID: 0000-0002-8767-9487) is currently working as an Assistant Professor at the State Key Laboratory of Lunar and Planetary Science (SKLPlanets)\, at Macau University of Science and Technology (MUST)\, in China. She is a microbiologist and has worked with a myriad of microorganisms (mycobacteria\, environmental and clinical bacteria\, mycobacteriophages and filamentous fungi) in several different countries (UK\, Saudi Arabia\, Portugal\, and China). Her research fits within astrobiology and astromycology\, focusing on: fungal ecology and biodiversity in environmental analogues to outer-space conditions\, fungal development under simulated outer-space conditions\, bioprospection and application of filamentous fungi\, and fungal growth containment (in the context of planetary protection) and exploitation to human needs in outer-space similar conditions. \nViews: 5

SUMMARY:OCA Outreach - Crystal Cove Grunion Run
DESCRIPTION:The biggest drawback is a moon that is one day past full. I inquired about new moon dates\, but Erin said that her schedule for those dates is full. \nSome of the northern and eastern sky is blocked off by a nearby bluff\, but\, in a kind of exchange\, the whole southern horizon is wide open\, offering people a view of targets rarely seen from Orange County. Polaris should be visible\, although it is fairly close; the northern horizon is at an elevation of about 29 degrees. And\, if you get there early enough and are able to align your scope before the guests begin arriving\, you may be able to witness the grunion run itself. We will be only about 100 feet from the high-water mark. \nViews: 5

SUMMARY:General Meeting – August 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from Tucson\, AZ.\n  \nThe Dynamic Eclipse Broadcast Initiative\,\n  \nand follow up projects!\n  \n \n  \nThe Dynamic Eclipse Broadcast (DEB) Initiative was a citizen science project for the 2024 total solar eclipse which transited North America on 8 April 2024. Nearly 400 citizen volunteers observed the eclipse with a set of standard equipment from about 70 location both inside and outside the path of totality. During the partial eclipse phases\, each site uploaded a processed solar image at a cadence of 1 per minute to our web page. For those sites located in the path of totality\, the volunteers collected a set of 5 different exposures every 5 seconds and then uploaded this data to our central repository. These coronal images are currently being processed with the goal of measuring the acceleration of coronal plasma in the inner corona. \nThe organization and training of the DEB volunteers\, their experiences on the day of the eclipse\, and the current status of the data analysis will be discussed. In addition\, the DEB Initiative follow-up projects which explore white light solar flares\, variable stars and asteroid observations will be discussed with the aim of inspiring more people to join our volunteer community. \n \nMatt Penn became interested in astronomy when his parents bought a 3″ Newtonian telescope for him while he was in 6th grade. While getting his undergraduate degree in astronomy at Caltech\, Penn did his senior research project using solar oscillations data and began a career in solar physics research. After getting his PhD from the University of Hawaii in 1992\, Penn worked with dozens of students\, published more than 70 peer-reviewed research papers and developed a citizen science project for the 2017 total solar eclipse. Leaving the research field in 2018\, Penn stayed with his family in Tucson AZ and is currently an electro-optical engineer. He holds two patents in the field of image processing. Penn continues to publish research papers in the field of astronomy as a hobby\, and enjoys hiking and travel. \n  \nViews: 5

SUMMARY:General Meeting – July 2024
DESCRIPTION:This is a free and open to the public hybrid event\, held both inperson and online.\nDue to the newly effective insurance requirements\, we regret that we can not allow people under 18 on the Chapman Campus\, they are welcome to attend online.\n Join Zoom\n\nThis meeting’s speaker will present online from Chicago.\n  \nWhat Cleaning the\n  \nInternational Space Station\n  \nCan Teach Us About a\n  \nHuman Health Crisis on Earth\n  \n \n  \nThe spread of antimicrobial resistance depends on many factors\, including previous exposure of microorganisms to antimicrobial disinfectants. Antimicrobial resistance in the environment ultimately translates into a human health risk. While antimicrobial chemical disinfection is used to prevent infection by pathogenic organisms\, it can inadvertently select for antimicrobial resistance. Disinfectants are not only used in hospitals and homes on Earth\, but also on the International Space Station (ISS). \nTo protect crew health\, cleaning the ISS primarily using a disinfectant containing the quaternary ammonium compound benzalkonium chloride (BAC) has been done for decades. BAC is not only found in disinfectants\, but a range of products from consumer antibacterial hand soap to dryer sheets. Due to its widespread use\, BAC has been detected throughout the indoor and natural environment\, where it has been linked to antimicrobial resistance. BAC use on Earth has increased dramatically in the past few years\, so findings on the ISS may also be indicative of changes in our Earth-based indoor microbiomes. To investigate the relationship between BAC disinfectant use and antimicrobial resistance\, Staphylococcus spp. isolates collected between 2009 and 2015 from the ISS were examined. Whole genome sequencing identified multiple BAC resistance genes in addition to resistance to other compounds. \nThis work highlights the importance of considering the long-term impact of antimicrobial disinfection when selecting cleaning products. Additionally\, the benefits of specific products to human health must be weighed against their ability to select for resistance and the long-term risk that then emerges. Examining a range of Staphylococcus spp. isolates for resistance markers has given us a greater understanding of how tolerance varies with specific BAC genes in the indoor environment. Additionally\, the ISS environment and long-term BAC disinfection seems to select for BAC tolerance. Further work is needed to understand if there are differences between the frequency of BAC resistance genes in the ISS compared to Earth-based environments. \nhere are links to a formal research paper about resistance on the International Space Station written by a previous lab member (for those interested in scientific journal style writing on this topic)\, and a more informal op-ed on use of cleaning chemicals and its relationship to antibiotic resistance. \n  \n \n  \nOlivia is an environmental engineer interested in fundamental rules that govern how microbes adapt to their environment. She received her Bachelor’s degree in Civil and Environmental Engineering from University of Maryland\, College Park where her research focused on optimizing developments to minimize stormwater flooding. She then moved to England to study in the Environmental Engineering Master’s degree program at Imperial College London. Her dissertation focused on barriers to the implementation of novel microbial wastewater treatment in Serbia. After completing her Master’s\, she spent a year working in industry as a consultant engineer for drinking water projects before returning to academia. Olivia recently completed her PhD in Environmental Engineering at Northwestern University in the Hartmann Lab where her research focused on how disinfectant use impacts antimicrobial resistance and strategies to combat the resistance trend. \n  \n  \nViews: 5
