"Europa Report" is relatively authentic in its details about the large, icy moon of Jupiter called Europa, But it is not perfect, and it will strike many viewers as, at first, slow and claustrophobic. After all, as one of the astronauts observes, the space inside the ship is extremely limited even while the space outside is vast.
That said, I recommend "Europa Report" for being sufficiently adventurous while not making the intelligent viewer cringe over obviously fake science. In fact, it is a horror movie made more horrifying by the plausibility that, just as there are dangers in nature here on earth, there might be equal or worse horrors lurking on the many moons and planets we have yet to explore.
There are some tropes here that are similar to those of other space movies, but many that are different, too. No, crew members do not become infected with an alien bug that makes them kill each other. Yes, they argue, but it is mostly about taking chances versus safety. The crew cooperates, and they take care of each other in admirable ways--if ultimately futile ones.
There are however, several don't-go-down-those-stairs moments. ("Actually walking on the surface of Europa was always a question mark," says one astronaut as the crew is about to vote on whether one of the scientist-astronauts should go outside.)
The scene that confused me most was the one about the attempted repair of the communications system; I thought they were all in the lander on Europa's surface, but apparently they left two astronauts on the orbiter high above the surface. Anyway, that is the first genuinely scary scene. There are subsequently some more scary scenes including the ending.
For those who do not know. Europa is Jupiter's fourth largest moon (Jupiter has well over 80 moons and moonlets), and it is one of three big Jovian moons that have liquids on their surfaces. In fact, Europa has an all-ice surface with nothing much other than a salt-water ocean beneath that ice. While the surface of this planet-sized moon is absolute zero degrees (utterly frozen), its innermost core is molten hot so that the salty ocean between the hot core and cold surface is relatively warm--warm enough that some of the creatures in earth's oceans would probably be able to live in Europa's ocean. So, does Europa have life of its own? That is what the astronauts in "Europa Report" want to find out.
There are some scientific quibbles: Although the movie acknowledges that radiation is a huge problem, it seems rather cavalier about it. (Europa is pretty close to Jupiter and is hit by 5.40 Sv of radiation a day; as I understand it, that quickly translates into deadly exposure.)
Another problem is that the movie assumes that the surface of Europa is rough but relatively flat; yet recent data suggests that the icy surface is made up of huge, closely interspersed ice-spikes; making landing a ship there similar to throwing a tennis ball at the sole of a boot cleated with sharp metal spikes.
Many advocates of a mission to Europa insist that we should send robots, not people. However, the filmmakers should be forgiven because danger to robots would not be as exciting as danger to humans. "Europa Report" gives us a crew of diverse humans who turn out to be relatable (if somewhat generic), who are nevertheless admirable in their determination and bravery.
