SUMMARY:Earth Observation Symposium
DESCRIPTION:Join MIT AeroAstro and Earth\, Atmospheric\, and Planetary Sciences (EAPS) for the Earth Observation Symposium\, a day-long exploration of satellite-based research and innovation for Earth Day on April 22 2026.  \nThis symposium will convene researchers from across MIT and affiliated networks to highlight how satellites allow us to monitor weather systems\, track climate change\, study ecosystems\, and better understand the patterns shaping our planet.  \nThe program features a keynote address by Susan Solomon\, Lee and Geraldine Martin Professor of Environmental Studies and Chemistry\, internationally recognized for her leadership in atmospheric science. The day will also include faculty talks and panels\, lightning talks and poster sessions from students and researchers\, and opportunities to connect with colleagues working across this interdisciplinary field.  \nCelebrate MIT’s pioneering role in Earth observation\, a field first explored right here in Boston\, and join us in exploring how satellite science continues to advance research\, technology\, and society. \nProgram\nPart 1\nEAPS Atrium\, Building 55 \n10:00–10:05 | Welcome and introduction | Prof. Olivier de Weck and Prof. Arlene Fiore \n10:05–10:10 | Symposium overview | Prof. Daniel Varon and Dr. Afreen Siddiqi \n10:10–10:55 | Keynote  \nSusan Solomon\, Lee and Geraldine Martin Professor of Environmental Studies and Chemistry \nInterpreting Earth observation regarding ozone\, detection and attribution of climate change\, and future challenges. \nBreak \n11:05–11:50 | Panel  \nEarth observation for environmental science and society: emerging technologies and applications at MIT \nSherrie Wang\, Assistant Professor\, MIT MechE\, IDSS\, and LIDS; PI of the Earth Intelligence Lab \nTaylor Perron\, Cecil and Ida Green Professor of Earth\, Atmospheric and Planetary Sciences\n \nDava Newman\, Apollo Program Professor\, Aeronautics and Astronautics \nDaniel Varon\, Boeing Career Development Professor in Aeronautics and Astronautics \n12:00–1:00 | Lunch + networking  \n1:00–2:00 | Lightning Talks \n\nFrederick Ajisafe\, “Use of methane point-source commercial satellite data to supplement local greenhouse gas inventories at a landfill in Rio de Janeiro”\nShahine Bouabid\, “Can real-world alignement of Earth System Model emulators project future lived conditions?”\nAllegra Farrar\, “CYGNSS”\nKevin Gauld\, “Quantifying Nitrogen Oxide Point Sources with the EMIT Satellite Imaging Spectrometer”\nJoe Palmo\, “Aerosol-Corrected Geostationary Nitrogen Dioxide Retrievals over Biomass Burning Plumes”\nAnna Papp\, “Open Dumps and the Global Trade in Garbage”\nEric Saboya\, “AGAGE: 48 years of measuring and monitoring global atmospheric trace gases”\n\n\n2:00–3:30 | Featured Speakers \nXiong Liu\, Senior physicist\, Center for Astrophysics\, Harvard & Smithsonian\nTEMPO Mission: The Smithsonian/NASA TEMPO observatory measures the atmosphere over North America from a geostationary satellite\, specifically tracking air quality in unprecedented detail. \nDara Entekhabi\, Bacardi And Stockholm Water Foundations Professor\, MIT Civil and Environmental Engineering\nThe Soil Moisture Active Passive (SMAP) Mission: Launched in 2015\, the SMAP satellite measured high-resolution global measurements of near-surface soil moisture and its freeze-thaw state.

SUMMARY:Dr. Sandeep Saha: Aerodynamics of Endurance
DESCRIPTION:Title:\nAerodynamics of Endurance: From Transoceanic Migratory Dragonflies to Micro-Air Vehicles \nAbstract:\nNature’s flyers exhibit unparalleled efficiency and resilience\, performing transoceanic migrations that challenge our fundamental understanding of low-Reynolds-number aerodynamics. We will explore the intersection of biology and engineering through the lens of Pantala flavescens\, a dragonfly capable of 14-18\,000 km annual round trip across the Indian Ocean in 4 generations i.e the longest known insect migration. By integrating biological observation with energetic analysis that is constrained by graph theory\, we uncover the mechanisms enabling such extreme endurance. We also examine the wing kinematics and aerodynamic performance of P. flavescens under varying wind conditions\, including tailwinds and crosswinds. Utilizing experimental data and computational modeling\, we probe how these insects utilize drift compensation and efficient flight in turbulent atmospheric flows. We then shift gears to highly accurate resolution of complex flow features using a novel pseudospectral method to mitigate Gibbs-Wilbraham phenomena in high-order numerical simulations\, aimed to precisely capture vortical structures. A central focus is placed on “two-fluid” and “thin-film” boundary layer stability—principles derived from classical fluid mechanics that may provide insight into the dragonfly’s highly efficient flight. We present findings on how wing surface morphology and kinematics influence lift-to-drag ratios at Reynolds numbers where conventional airfoil theory fails. Beyond biological inquiry\, we propose novel concepts for the next generation of Micro-Air Vehicles (MAVs). By fusing insights from insect migration networks with dart-shaped projectile aerodynamics\, we propose innovative design paradigms for autonomous systems capable of long-range\, energy-efficient flight. The talk concludes by highlighting how the synergy between integrative biology and aerospace engineering can solve persistent challenges in low-speed aerodynamics. \nLink: https://www.frontiersin.org/articles/10.3389/fevo.2023.1152384/full \nSpeaker Bio:\nDr. Sandeep Saha is an Associate Professor in the Department of Aerospace Engineering\, IIT Kharagpur. He obtained his bachelor’s and master’s degrees in mechanical engineering from IIT Kharagpur. He completed his PhD in Mechanical Engineering from Imperial College London. He thereafter worked as a Marie-Curie Experienced Researcher\, CNRS (Laboratoire FAST)\, Orsay\, France. Thereafter\, he worked as an Aerodynamics Engineer\, ALSTOM Power (now GE)\, Rugby\, UK; then as Research Scientist (Fluids)\, Schlumberger Gould Research\, Cambridge\, UK; and then as Academic Staff member\, Mechanical Engineering\, University of Duisburg-Essen\, Germany (in collaboration with SIEMENS AG). He has worked on a range of problems in fluid mechanics and\, in recent years\, has focused on Low Reynolds number Aerodynamics ranging from a broad spectrum of problems like insect flight\, extraterrestrial flight\, respiratory flows\, waste heat recovery\, and sports aerodynamics. \nFor any questions\, please contact Jasmine Aloor at jjaloor@mit.edu.
