Current Schedule (expanded):

1/7/2016 – Jan-Erik Wahlund; Heavy Metal – An ESA M5 mission to a metallic asteroid

Speaker:   Jan-Erik Wahlund (Swedish Institute of Space Physics)
Date & Time:   1/7/2016 ,  4:00 PM Location: SPSC N100

(16) Psyche is the largest known M-class asteroid (240 x 185 x 145 km), and a density of 5 – 8 g/cm(3) is inferred from orbit perturbations of nearby asteroids. Other ground observations suggest that the surface and dust around this object is iron-nickel rich with very little water. These observations are important considering the […]

1/14/2016- Deanne Rogers; Understanding Early Martian Surface Processes and Environments through Visible and Infrared Mapping of the Ancient Highlands

Speaker:   A. Deanne Rogers (Stony Brook Univ.)
Date & Time:   1/14 ,  4:00 PM Location: SPSC W120

An important aspect of community-wide efforts to understand the geologic and climatic history of early Mars is to constrain the style(s) and timing of resurfacing events in the Noachian. The cratered plains of the ancient highlands exhibit diversity in compositional and thermophysical properties, providing some constraints on the resurfacing history and thus the processes and […]

1/21/2016 – Brian Fleming; Lyman Alpha and Lyman Ultraviolet Emission from Stars and Galaxies – Instruments and Techniques for Science in the UV

Speaker:   Brian Fleming (LASP)
Date & Time:   1/21 ,  4:00 PM Location: SPSC W120

Low material transmission and reflection in the far-ultraviolet has posed a major constraint on astronomy in the observed-frame UV. The most prominent NASA observatory with sensitivity in the Lyman ultraviolet, FUSE, had limited angular resolution and high background equivalent flux introduced by the need to minimize reflections to maintain effective area. The spectroscopic imaging capabilities […]

1/28/2016 – Leslie Young ; The Pluto system as seen by NASA’s New Horizons spacecraft

Speaker:   Leslie Young (SwRI)
Date & Time:   1/28 ,  4:00 PM Location: SPSC W120

When NASA’s New Horizons spacecraft flew past Pluto and its five moons last July, it revealed a beautiful, varied, and puzzling system.  Pluto’s surface ranges from dark and cratered terrains, to tall mountain ranges, to geologically young ice flows.  Charon sports a completely unexpected dark, reddish area near its north pole.  Pluto’s atmosphere is hazy […]

2/4/2016- Bill Bottke; The Calm Before the Storm: Exploring the Post Accretionary Doldrums Prior to the Late Heavy Bombardment

Speaker:   Bill Bottke (SwRI)
Date & Time:   2/4 ,  4:00 PM Location: LSTB 299

The early bombardment of the inner solar system played a critical role in planetary evolution, but there is still considerable uncertainty about what happened when. Dynamical models suggest two major bombardment phases may have taken place: (i) a post-accretionary period where newly-formed worlds were struck by leftover planetesimals, and (ii) a late heavy bombardment period, […]

2/11/2016- Cathy Olkin; Pluto’s Atmosphere and Surface Composition

Speaker:   Cathy Olkin (SwRI)
Date & Time:   2/11 ,  4:00 PM Location: SPSC W120

After traveling for more than 9 years, NASA’s New Horizons mission accomplished its prime objective – the initial reconnaissance of the Pluto system. On July 14, New Horizons passed about 12,500 km from Pluto’s surface, flying between Pluto and the orbit of Pluto’s large moon Charon.  The seven instruments on board the spacecraft include a […]

2/18/2016- Ed Thiemann; A Lumped Element Thermal Model for the Cooling Phase of Solar Flares

Speaker:   Ed Thiemann (LASP)
Date & Time:   2/18 ,  4:00 PM Location: SPSC W120

Solar flares are the result of magnetic reconnection in the solar corona which converts magnetic energy into kinetic energy resulting in the rapid heating of solar plasma.  Characterizing how this hot plasma subsequently cools is important for understanding the evolution of flares and the corresponding heating of the quiescent corona.  Because the flare soft x-ray […]

2/25/2016 – Jeannette Heiligers ; “Sailing on Sunlight” – solar sails for planetary science

Speaker:   Jeannette Heiligers (Univ. of Strathclyde)
Date & Time:   2/25 ,  4:00 PM Location: SPSC W120

The 21st of May 2010 saw the dawn of a new era in space propulsion when the Japanese Space Agency, JAXA, launched its IKAROS spacecraft. Twenty days into the mission, IKAROS unfurled a 14×14 m2 solar sail that would take the probe on a six-month voyage to Venus, propelled solely by the solar photons reflecting […]

3/3/2016 – Tom Woods; Jack Eddy’s Study of the Maunder Minimum Inspires a Long Series of Satellite-Based Solar Irradiance Measurements: LASP and HAO solar irradiance projects between 1970 and 2010

Speaker:   Tom Woods (LASP)
Date & Time:   3/3 ,  4:00 PM Location: SPSC W120

What if Jack Eddy hadn’t rediscovered the work by Gustav Spörer and Edward W. Maunder about the period of few sunspots in the 17th century? Would there be much interest today in understanding the solar “constant”, or would there be robust observational programs in measuring the solar irradiance and its variability and studies about Sun-Climate? […]

3/10/2016- Erik Richard; Long-term Measurements of Solar Spectral Irradiance: Lessons learned and the Path Forward

Speaker:   Erik Richard (LASP)
Date & Time:   3/10 ,  4:00 PM Location: SPSC N100

Accurate, long-term solar spectral irradiance (SSI) measurements are vital for interpreting how solar variability affects the balance of the Earth’s total energy budget and for validating climate model sensitivities to spectrally varying solar forcing. Ultimately, understanding these effects requires continuous measurements of SSI that meet the stringent requirements of climate-quality accuracy and stability over time. […]

3/17/2016- Open

Speaker:   TBD
Date & Time:   3/17 ,  4:00 PM Location: SPSC N100


3/24/2016- Jeremiah Sjoberg (NOAA)

3/28/2016 – Greg McFarquhar; Use of In-Situ Observations for Quantifying Ice Cloud Microphysical Properties and Processes, and their Uncertainties

Speaker:   Greg McFarquhar (U of Illinois)
Date & Time:   3/28 ,  3:00 PM Location: SPSC W120

Some of the most fundamental and complex problems in climate and weather research today are our poor understanding of the basic properties of clouds and our inability to determine quantitatively the many effects that clouds have on weather and climate. The representation of ice microphysical processes such as riming, sedimentation, aggregation, evaporation and deposition has […]
