Laboratory for Atmospheric and Space Physics (LASP)

Origins, Worlds and Life, Decadal Survey for Planetary Science & Astrobiology

When
-

Abstract: We summarize the recommendations of the latest Decadal Survey for priority science questions, missions, budgets and state of the profession. We can discuss lessons learned and opportunities with the attendees.

LASP seminars are generally held every Thursday at 4:00 PM on Zoom and in person:

PILOT: Plasma Imaging, LOcal measurement, and Tomographic Experiment, a Mission Concept for Transformational Multi-scale Observations of Cold Plasma Dynamics in Earth’s Magnetosphere

When
-

Abstract: Magnetospheric physics has a massive problem: we have not yet determined the fundamental processes that govern plasma mass and energy flow through the terrestrial magnetosphere, nor the degree to which these flows regulate key magnetospheric subsystems. Knowledge of these processes is critical to understanding the mass loss rate of Earth’s atmosphere, as well as for determining the role that a planetary magnetic field plays in atmospheric retention, and therefore habitability, for Earth-like planets beyond the solar system.

Past and Future Exploration of Enceladus and Europa: an Icy Dust Analyzer Perspective

When
-

Abstract: Enceladus has become the iconic example of an active icy moon where the subsurface ocean cryo-volcanically communicates with the surface and in fact the surrounding space. In the first part of the talk, the main findings from the Cosmic Dust Analyzer (CDA) and other instruments about Enceladus after the end of the Cassini mission are presented.

The Geologic Wonderland of Pluto and the Largest Cryovolcanic Constructs in the Solar System

When
-

Abstract: In July of 2015 the New Horizons spacecraft flew through the Pluto system, initiating detailed exploration of the Kuiper belt. Pluto turned out to be a world of remarkable geologic diversity, and its surfaces display a range of ages, suggesting geologic activity of various forms has persisted for much of Pluto’s history. Pluto has some familiar features (e.g., tectonics, cratering) but also features that are unique (e.g., a giant convecting nitrogen ice sheet, and large cryovolcanic constructs).

Towards an Exoplanets Demographics Ladder Seminar Abstract:

When
-

The NASA Kepler mission has provided its final planet candidate catalogue, the K2 mission has contributed another four years’ worth of data, and the NASA TESS mission has been churning out new planet discoveries at a rapid pace. The demographics of the exoplanet systems probed by these transiting exoplanet missions are complemented by the demographics probed by other techniques, including radial velocity, microlensing, and direct imaging.
