While this is a pretty standard workflow for shooting liquids my take on it was to push the outcome in post so hard that it becomes almost indistinguishable from CGI generated particles. Real world practical effects have proven to deliver the tangibility I was looking for in order to illustrate the metaphysical aspects of space travel.
VFX, HUD animation and compositing was done in After Effects. All HUD elements have been replicated from the Apollo Lunar Excursion Module. It was great fun diving into NASA's design world and collecting all sorts of references like realistic light fall-off in space, HUD elements and even spaceship interiors.
Fun trivia: the landing point designator shown in two shots consists of a set of lines scribed onto the inner and outer panes of the commander‘s forward-facing window. The commander positions himself in such a way that the two sets of lines are superimposed in order to precisely determine the designated landing site. Despite having the most sophisticated computers on board the designator was utterly indispensable.
