Private Funding Opportunities for Space Research

Kollipara Horgan Bunger

Join our three expert panelists to find out about opportunities for funding science with venture capital and other commercial opportunities.

This event is co-hosted with the NIAC workshop, to be held at Stanford Feb 4-6 2014.


Thermal History of Planetary Objects: From Asteroids to super-Earths, from plate-tectonics to life

super earthConvection in the interiors of planetesimals (asteroids), planets, and satellites is driving the thermal and chemical evolution of these bodies including the generation of possible magnetic fields.  The wide size range induces a wide range of time scales from hundreds of thousands of years for small planetesimals to a few tens of Gigayears for massive super-Earths.

Ocean Surfaces on Snowball Earth

snowball earth

Dr. Warren will discuss the Snowball Earth events in Earth history, when the ocean apparently froze all the way to the Equator. These events were qualitatively different from the recent ice ages of the Pleistocene, in which ice sheets advanced over large parts of the northern continents.  On Snowball Earth, by contrast, Warren will argue that most of the action was in the ocean. 

Climate Change Impacts in the Arctic Ocean

Sea ice in the Arctic Ocean is in rapid decline.  This reduction in ice extent and thickness has resulted in a longer open water season and higher marine productivity.  Until recently, phytoplankton blooms on continental shelves were thought to be restricted to waters free of sea ice.

Europa's Great Lakes

With an icy exterior covering a global ocean, Europa has long been a target of interest in the search for life beyond Earth.  Europa exists in a dynamic environment, subject to intense irradiation and impact as well as immense tides from Jupiter.  These processes deliver important thermal and chemical energy that could be critical to supporting a putative biosphere. In the past few decades the debate about habitability of Europa has been focused strongly on the thickness of the ice shell.  However, an arguably more critical question is: how does the ice shell recycle?

Planet formation and stellar multiplicity: insights from recent surveys and perspectives

While the prevalence of stellar multiplicity has been known for many decades, it is now becoming increasingly clear that planetary systems are also frequent around Main Sequence stars. This raises the natural question of the connection between stellar multiplicity and planet formation, a topic that was mostly ignored until the last few years. Does the presence of a stellar companion alter, prevent or promote the formation of planets? In which way?

Planetesimal Migration in the Early Days or Taking the Solar System by Störmer

Common wisdom holds that, in order for a terrestrial planet to have life, it's helpful to have a Jupiter-like planet in the system to shield against inbound comets. How well does Jupiter do that really? Common wisdom held until recently that it would be an impossible for an icy object like Ceres to exist within the inner Solar System. From where did the ice come? Common wisdom held until recently that the Centaur asteroids and Kuiper Belt objects were dynamically distinct. Are they?
