Plot.
Captain William Stanaforth (Strong) is on a one-way solo mission to Mars, taking humanity’s first steps towards colonizing it. Although the entire world is watching him, he is completely alone on the space ship. After liftoff and the subsequent rocket separations, Stanaforth takes his suit off to relax and is set on course to Mars by the team on the ground.
Through flashbacks we see how Stanaforth had come up with the idea to create water () by supercompressing sand/dirt and combining the separate hydrogen and oxygen byproducts. It is by this synthesis that the mission is made possible.
Stanaforth's water generation apparatus malfunctions during his mission to Mars. Rather than return to Earth as protocol requires, he takes manual control of his spacecraft and continues to Mars. His spacecraft becomes entangled with a nebula and through voiceover we hear Stanaforth ruminate on the nature of matter and space. Stanaforth says, "This is why I came here. To give everything up. For one moment of pure wonder." Stanaforth is then seen in his spacesuit, exiting the spacecraft.
Without explanation, the scene cuts to Stanaforth, clean-shaven in his spacecraft, preparing to land on Mars. Stanaforth lands on, then walks, on Mars. As he walks, we hear Stanaforth say, "Nothing has ever lived here. Nothing has even died here. Maybe I'll live forever."
Release.
In April 2016, Vertical Entertainment acquired U. S. distribution rights to the film, while Paramount Home Media Distribution acquired home media distribution and video on demand rights. The film was released on June 3, 2016.
Critical reception.
The film has received mixed reviews from critics. It has a critic approval rating of 45% on the review aggregator Rotten Tomatoes with an average rating of 5/10 based on 20 reviews. It also has a score of 53 out of 100 on Metacritic, based on 13 critics, indicating "mixed or average reviews".
Despite its mixed reactions, Strong's performance was praised, with Ben Kenigsberg of "The New York Times" saying: "If "Approaching the Unknown" isn't entirely satisfying, Mr. Strong reaches high with his portrayal of the unraveling of a man who believes survival is a matter of engineering."
