Searching for Lunar Water with LunaH-Map: Tiny Interplanetary Spacecraft With Big Science and Exploration Goals (Craig Hardgrove, Arizona State University),
Virtual 
LunaH-Map is a new type of NASA planetary science mission manifested for launch on Space Launch System Artemis-1. Following in the footsteps of the MarCO cubesat's successful interplanetary mission, the LunaH-Map spacecraft is a miniaturized, shoebox-sized, interplanetary spacecraft that will use a small ion propulsion system to navigate into lunar orbit and a neutron spectrometer to map enrichments of hydrogen across the lunar South Pole. The maps produced by LunaH-Map will help constrain the amount of hydrogen within permanently shadowed regions, which will inform our understanding of sources and sinks for polar volatile deposits, as well as planning future lunar exploration missions.

A Subterranean Hydrothermal System and Microbial Nursery Beneath the Floor of the Chicxulub Impact Crater (David A. Kring, Lunar and Planetary Institute),
Virtual
An expedition sponsored by the International Ocean Discovery Program and International Continental Scientific Drilling Program recovered rock core from the peak ring of the ~180 km-diameter Chicxulub impact crater. Mineral assemblages in the core indicate the crater hosted a substantial and long-lived hydrothermal system. Furthermore, sulfur isotope compositions of pyrite framboids that precipitated in the hydrothermal system indicate it was inhabited by sulphate-reducing thermophilic organisms. The findings support the impact origin of life hypothesis, which posits prebiotic chemistry and the early evolution of life occurred in similar impact-generated systems during the Hadean on Earth and potentially in other planetary systems where similar hydrothermal systems are generated.

MSR Sample Caching Strategy Workshop,
Virtual
In October 2020, NASA and ESA formalized a partnership to bring samples of Mars to Earth. One crucial piece of planning that will have a large impact on the potential number, nature, and diversity of returned samples, and thus on the science that can be performed on the samples, is the caching strategy for the samples collected by the rover Perseverance. The delivery of cached samples to the Sample Retrieval Lander (SRL)is possible via transport by two pathways: 1) retrieval of samples cached on the Mars surface by the Sample Fetch Rover (SFR) and then transport to the Sample Retrieval Lander; and/or 2) delivery of samples retained on Perseverance to the SRL. Thus, there are multiple options for caching. The samples can be cached in one or more depots on the surface of Mars, and the Perseverance rover itself can carry a cache, allowing one or both of the above pathways to be utilized. Which strategies are actually implemented will depend on the nature and perceived value of each sample, the diversity of the samples at a depot, landing site accessibility for SRL, the capabilities of Perseverance and Sample Fetch Rover, lifetime projections for Perseverance and SFR, and the projected risk of rover survivability and trafficability of the terrain encountered. Potential scenarios may include acquiring duplicate samples as well as where, when, and how many depots are established. We solicit your participation in a four-hour workshop on January 21, 2021 (8am-12pm PST) to consider the strategy for establishing the caches on Mars. Key discussion points wil include: • What are the minimum attributes of a cache that warrants sample return? • What should be the strategy for duplicate sampling? • What approach(es) will offer the best balance between minimizing risk and maximizing the scientific value of the samples to be returned? The workshop will present a review of relevant material, and a forum for community discussion on possible viable scenarios for a sample caching strategy. More detailed information will be forthcoming. Please let us know of your interest so we can properly scope the meeting by filling out the Indication of Interest form at https://forms.gle/gf4rxQ1BjFqdVe9BA.

A Tale of Lunar Water (Casey Honniball, Goddard Space Flight Center),
Virtual
For decades the lunar surface was believed to be anhydrous, however, reports by three independent spacecraft in 2009 changed this view when they detected a 3 µm hydration band on the Moon. The 3 µm absorption band is attributed to hydroxyl (OH) and possibly molecular water (H2O). The band exhibits variations with lunar time of day, temperature, soil maturity, and composition that has been interpreted as variations in water concentrations.
Data from an infrared spectrometer, the Moon Mineralogy Mapper (M3) onboard the Chandrayaan-1 spacecraft, is widely used to study the 3 µm band, its spectral range, however, only covers half the hydration band. Due to the limited wavelength range of M3, variations of hydration has been called into question. To investigate the validity of variations in the 3 µm band we used the Spex infrared cross-dispersed spectrograph at the NASA InfraRed Telescope Facility (IRTF) at Maunakea Observatory in Hawaiʻi. Our improved data showed that the variation in hydration is real.
But is hydroxyl or water responsible for the variations? Distinction between OH and H2O from spacecraft measurements at 3 µm is difficult due to their similar spectral properties. We have developed a new approach for unambiguous detection of the water molecule on the sunlit lunar surface. At 6.07 µm the fundamental H-O-H bend of H2O is exhibited and is strictly due to H2O without contribution by OH. The only current observatory capable of 6 µm observations of the Moon at 6 µm is the Stratospheric Observatory For Infrared Astronomy (SOFIA). Using data from SOFIA we report the first direct detection of the water molecule on the sunlit lunar surface.

Regional Atmospheric Dynamics of Water in Valles Marineris, Mars (Cecilia W.S. Leung, Jet Propulsion Laboratory),
Virtual
Water vapor in the planetary boundary layer is substantially influenced by local topographic gradients. Using a mesoscale atmospheric model, we investigate the convergence of regional moist air masses that forces asymmetries between the day-night concentrations of water in the canyon system. I will discuss the conditions under which water ice fogs may form inside Valles Marineris, and the implications for deliquescence and brines that may result from an atmospheric reservoir.

Potassium isotope anomalies in meteorites inherited from the protosolar molecular cloud (Yaray Ku, Harvard University),
Virtual
Potassium (K) and other moderately volatile elements are depleted in many solar system bodies relative to CI chondrites, which closely match the composition of the Sun. These depletions and associated isotopic fractionations were initially believed to result from thermal processing in the protoplanetary disk, but so far, no correlation between the K depletion and its isotopic composition has been found. In this talk, I will present our high-precision K isotope data correlated with other neutron-rich nuclides (e.g., 64Ni and 54Cr), suggesting the observed 41K variations of a nucleosynthetic origin. In addition, I will present new K isotope data from individual chondrules and matrix analysis during this talk. Our data support that K isotope anomalies are inherited from an isotopically heterogeneous protosolar molecular cloud, and were preserved in bulk primitive meteorites.

Lunar Surface Science Workshop,
Virtual Session 8: Structuring Real-Time Science Support of Artemis Crewed Operations
When astronauts walked on the Moon during the Apollo program, scientists were embedded in the Flight Control Team (FCT). These scientists populated a science backroom, and they were responsible for helping direct science activities, including sampling, instrument deployment, and other exploration tasks. In this way, the science backroom was critical in maximizing the productivity of the Apollo missions. Part of the reason for their success was that the scientists were able to work closely with the flight controllers, astronauts, and other critical members of the Apollo Program before, during, and after the missions. In the same way, scientists will work with Artemis Program flight controllers, flight directors, astronauts, and spaceflight engineers to achieve mission success and maximize scientific productivity by ensuring that the Artemis lunar surface missions effectively and efficiently accomplish high-priority science objectives.

The End-Cretaceous Planktic Foraminifera Crisis Linked to Ocean Acidification? (Jahnavi Punekar
Dept. of Earth Sciences
Jahnavi Punekar, IIT Bombay),
Virtual
The Cretaceous-Palaeogene boundary event (K-Pg; ~66 Ma) is well known for the demise of >70% life on Earth, including the non-avian dinosaurs. It is one of the BIG FIVE mass extinctions of the Phanerozoic, the only one linked with two triggers- the Chicxulub impact (Yucatan peninsula, Mexico) and Deccan volcanism (India). Recent high-precision U-Pb ages constrain Deccan volcanism between ~66.3 Ma and ~65.6 Ma1. Mercury chemostratigraphy coupled with planktic foraminifera biostratigraphy have enabled unprecedented correlation of the timing, tempo and extent of the end-Cretaceous faunal, climatic and environmental perturbations with Deccan eruptions2. In the main Deccan province (India), the K-Pg boundary is now inferred to be at the top of the Poladpur Formation - a likely catastrophic high-volume eruptive event that lasted <100 kyr1. Proximal K-Pg sequences in the Krishna-Godavari basin intertrappeans (India) document >90% planktic foraminifera species going extinct in response to correlative lava megaflows3. The distal western Tethyan sites reveal a “poor-carbonate-preservation” interval4 with high planktic test fragmentation, increased abundance of opportunist taxa (Guembelitria spp.) and intraspecific dwarfing immediately preceding the K-Pg boundary. Experimental validation of preservation-based proxies lends support to this end-Cretaceous acidification hypothesis. Coeval bulk-rock low magnetic susceptibility and peak mercury signals firmly tie this acidification to ongoing Deccan volcanism5. The biological, taphonomic and geochemical evidence strongly support an ocean acidification interval that persisted for <52 kyr (~2 precession cycles) prior to the K-Pg boundary. The age, duration and nature of this acidification event are better explained by recurrent pulses of Deccan volcanism than the geologically instantaneous Chicxulub impact.

Bifurcation of planetary building blocks during Solar System formation (Tim Lichtenberg, Oxford University),
Virtual
The origin of the Solar System shapes our understanding of the physical and chemical processes that drive planetary formation and early evolution. Geochemical analyses of meteoritic materials and astronomical observations of circumstellar disks provide evidence for a fragmented planet formation process. In the Solar System this manifested as two spatially and temporally separated reservoirs that accreted to form the inner, volatile-depleted and outer, volatile-rich planetary populations. The origin of this dichotomy is unknown. In this talk I will discuss our recent work on how the build-up and earliest evolution of the solar protoplanetary disk can influence the timing of protoplanet formation and their internal evolution. Migration of the water snow line during the Class I and Class II disk stage can generate two distinct bursts of planetesimal formation that sample different source regions of interstellar materials. These reservoirs evolve in divergent geophysical modes and develop distinct volatile contents, consistent with constraints from planetary accretion chronology and volatile composition, thermochemistry of extraterrestrial materials, and the mass divergence of inner and outer Solar System. Our simulations suggest that the compositional fractionation and isotopic dichotomy of the Solar System observed today was initiated by the interplay between disk dynamics, heterogeneous accretion, and internal evolution of forming protoplanets.

Distributed Volcanism and Distributed Volcanic Hazards,
Flagstaff, AZ
Most subaerial volcanoes are found in widely distributed volcanic fields made up of tens to hundreds of vents. Eruption styles and potential impacts also vary. Explosive activity ranges from mild Strombolian and ash-producing eruptions that produce localized tephra fall to more explosive eruptions that result in widespread ashfall. Effusive eruptions can produce far-reaching lava flows, and non-eruptive open-vent outgassing degrades downwind air quality. Many distributed fields on Earth are poorly instrumented and their eruptive histories are not well understood, which limits our ability to forecast the potential location, timing and magnitude of future eruptions.
The purpose of this Chapman is to bring together scientists to discuss, develop, and test conceptual models of distributed volcanism. Focus by the scientific community is especially important now because of continuing growth of cities, communities, and critical infrastructure within sparsely monitored volcanic fields.

2021 Sagan Summer Workshop: Circumstellar Disks and Young Planets
The 2021 Sagan Summer Workshop will focus on young planets and the circumstellar disks from which they form during the first few million years of a star's lifetime. As a protoplanet accretes material from the disk, dynamical interactions drive migration and produce disk substructures such as the gaps, rings and spirals now detected in high-resolution optical, near-infrared, and submillimter images. Over the next 100 million years, planetary systems continue to evolve through processes such as collisions, differentiation, and scattering. These late-epoch evolutionary processes are reflected in the structure and distribution of secondary dust disks. These debris disks, formed as the result of planetesimals stirring, serve as signposts for the presence of planetary systems.
As with last year, we expect that the 2021 workshop will be fully virtual. However we will post updates to this page should that change.
The Sagan Summer Workshops are aimed at advanced undergraduates, grad students, and postdocs, however all are welcome to attend. There is no registration fee for these workshops.
Attendees will also participate in hands-on tutorials and have the chance to meet in smaller groups with our speakers.

Spatially Resolved Spectroscopy with Extremely Large Telescopes,
Oxford, UK
Due to the ongoing uncertainty with COVID-19, this workshop has been postoned until 2021. Please save the weeks of Sept. 13-17 and Sept. 20-24. The new dates will be confirmed ASAP.
The forthcoming generation of Extremely Large Telescope (ELTs) will reach unprecedented spectroscopic sensitivity coupled with high angular resolution in the near infrared. This workshop will bring together the international astronomical community to explore the transformational science that the spectroscopic instrument suites of the ELTs (GMT, TMT and ELT) will achieve. High resolution simulations have played a key role in the development of the instrument science cases providing a quantifiable means to determine feasibility and to predict the scientific outcomes that can be achieved. By bringing together theoreticians, modelers and observers, with interests ranging from exoplanets to cosmology, the goals of the workshop are to: explore the spectroscopic capabilities of the first‐light instrument suite of the ELTs identifying synergies and complementarities between them; encourage development of ELT science cases including preparatory projects on existing telescopes; provide hands‐on experience using the HARMONI simulator (H-SIM); encouraging collaboration and transfer of expertise between the instrument teams and the wider community; and explore synergies with other facilities.
The meeting will set the stage for the community to plan and coordinate ELT science programmes and pre-cursor observations, making use of quantitative estimates of what the ELTs can achieve.

Gaps, Rings, Spirals, and Vortices: Structure Formation in Planet-Forming Disks,
Munich, Germany
Planets are formed inside the ubiquitous disks found around young stars. The unprecedented resolution and sensitivity of ALMA and high contrast infrared imagers have revealed spectacular features, such as gaps, rings, spirals, and vortices. It is now clear that disks are much more complex, dynamic objects than previously thought and a full explanation of the richness and diversity of features presents a formidable challenge to modelers.
This MIAPP program will bring together theorists and observers of circumstellar disks to join forces to decipher these observations and find new ways to probe the processes that drive disk evolution. The program format emphasizes time for discussions and collaborative work with a small number of focused presentations intended to foster interactions.
