Earth's Strange Twin: the Venus Paradox - Dr. James Garvin, NASA

Dr. James Garvin is the NASA Goddard Space Flight Center Chief
Scientist, currently focused on two main projects - massive
terrestrial impacts, and the mysteries hidden beneath the clouds
of Venus. Based off of lunar and Martian observations, Garvin
believes that our models for the history of impacts on Earth
might be nowhere near severe enough. Then there’s also the
ambitious DAVINCI mission to Venus, which will launch in 2029
with the goal of getting a glance under Venus’ thick cloud
atmosphere for the first time since the Soviet Venera landers of
the 1970s. We talk impacts, solar system formation, oddities of
tectonic activity in the solar system, and the twin history of
Venus and Earth. Support the scientific revolution by joining our

studying bioelectricity at Columbia University. When not talking
to brilliant people or making movies, she spends her time
painting, reading, and guiding backcountry excursions. Michael
Shilo also did his PhD at Columbia studying the elastic
properties of molecular water. When he's not in the film studio,
he's exploring sound in music. They are both freelance professors
at various universities. - Blog: http://DemystifySci.com/blog -
