I can't get a signal <a href=" http://jillianreilly.com/apa-editing-services/#neat ">essays themes</a> A space-exploration story told almost entirely through the use of video feeds (Embeth Davidtz appears as the team’s earthbound commander, leading a team of scientists in a press conference), director Sebastian Cordero’s movie is claustrophobic and gripping. As Earth’s first manned trip to a moon of Jupiter commences to discover if a single-cell organism exists there, the astronauts — two women and four men (including Sharlto Copley of “District 9”) — go about their scientific duties. As the tense journey reaches ice-covered Europa, disaster and fear bedevil the mission.
