SUMMARY:Space Weather and Space Systems – Online Short Course
DESCRIPTION:Through May 14\, this course will demystify the space weather topic\, new to many people\, as it affects a wide variety of space systems. The course will provide a conceptual foundation without requiring pre-existing knowledge. 6 weekly modules are Thursdays 15:00-17:00 EDT | 19:00-21:00 UTC | 09:00-11:00 HST. All sessions will be recorded and available for replay; course notes will be available for download. \nInstructor Joseph Comberiate is also course developer for the ‘Space Weather and Space Systems’ graduate course at Johns Hopkins University. He is the Group Supervisor of the Space Algorithms and Technologies group at JHU Applied Physics Lab\, where he has worked since receiving his Ph.D. in 2006 in Electrical Engineering from the University of Illinois Urbana-Champaign. His dissertation focused on tomographic reconstruction of ionospheric electron density using space-based ultraviolet observations. He also holds M.S. and B.S. degrees in Electrical Engineering from University of Illinois. \nBetween lectures during the course\, the instructor will be available via email for technical questions and comments. \nThis new essential course\, in partnership with Johns Hopkins University\, explores the space environment in the context of its impact on space system operations. \nStudents will receive an AIAA Certificate of Completion and an additional Certificate of Completion from Johns Hopkins University at the end of the course. \n  \n

SUMMARY:5th International Academy of Astronautics (IAA) Conference on Space Situational Awareness (ICSSA)
DESCRIPTION:At GMV\, Santiago Grisolia 4\, Tres Cantos. Conference Chair is Riccardo Bevilacqua of Embry-Riddle Aeronautical University. The foremost purpose of Space Situational Awareness (SSA) is to provide decision-making processes with a quantifiable and timely body of evidence (predictive / imminent / forensic) of behavior(s) attributable to specific space domain threats and hazards. The conference will cover broad-ranging technical and policy related aspects associated with the topic of SSA.

SUMMARY:Minding the LEO Gap and the Future of Commercial Space Stations
DESCRIPTION:Examining the findings of the Beyond Earth Institute’s 2025 Commercial Space Stations Working Group report\, which evaluates whether NASA’s multi-phase CLD strategy can successfully sustain a continuous American presence in low Earth orbit while enabling a commercially viable space economy. Online at 13:00-14:00 EDT | 17:00-18:00 UTC | 07:00-08:00 HST \nIn addition\, the discussion will address recent updates to NASA’s CLD approach\, including the proposed shift toward a government-owned core module and a hybrid development model\, and consider how these changes may reshape industry expectations\, regulatory frameworks\, and the long-term structure of the commercial LEO ecosystem. Drawing on insights from industry leaders\, policymakers\, and technical experts\, the panel will explore the legal\, regulatory\, and operational constraints shaping this transition\, as well as the strategic implications for U.S. leadership in an increasingly competitive orbital environment.

SUMMARY:Perihelion of Comet C / 2026 A1 (MAPS)
DESCRIPTION:Predicted date for the comet to make a close pass by the Sun (perihelion)\, potentially triggering a sudden brightening and dramatic tail. If it survives the encounter\, it may become visible to the naked eye. This event is part of a rare opportunity in April to potentially view two comets—C/2026 A1 and C/2025 R3 (PANSTARRS)—without telescopes\, with the latter expected to brighten later in the month.
