Well, it depends. If it's from a reliable source and has proper documentation, it's more likely to be based on a true story. But sometimes, reports can be fictionalized for various reasons.
Well, 'Europa Report' is sort of based on a true story in the sense that it draws from our current scientific knowledge about Europa. Scientists believe that Europa, one of Jupiter's moons, has a subsurface ocean that could potentially harbor life. The movie takes this scientific premise and creates a fictional story around a mission to explore Europa. It incorporates real - life space exploration techniques and the challenges associated with them. So, while it's not a true story in the traditional sense, it has a lot of elements rooted in real science.
Yes, generally if a report is based on a true story, it has a certain degree of reliability. It means that it has real - life events or situations as its foundation. However, the reliability also depends on the source and how the report is presented. For example, if the reporter has a bias or misinterprets some facts during the reporting process, it may affect the overall reliability of the report.
