“Europa Report” is already being described as one of the most realistic and believable films for space travel.

And there are some good reasons. NASA JPL scientists Steve Vance and Kevin Hand were consultants on this ambitious movie project about astronauts traveling to Europa, Jupiter’s moon, in the search for life.

The movie’s confined space, space travel and Europa’s surface environment were thoroughly researched with these scientists.

These two NASA JPL scientists took their vacation time to attend San Diego Comic-Con International 2013 to discuss the realism of “Europa” and other facts about space travel and Europa.

The movie stars Sharlto Copley, Embeth Davidtz, Christian Camargo, Michael Nyqvist and Karolina Wydra.

“Europa Report” will be in theaters on August 2nd and is already On Demand.
