NASA

NASA is an education app that makes the agency’s images, mission updates, and space material easier to browse than scattered web pages do. By our assessment, its strongest point is the directness of the source: it lets people meet NASA content without hunting through a mess of unrelated sites. The limit is obvious too, because an education app from a famous space agency is still an information app, not a toy or a classroom replacement. In practice it should feel like a reference window, best when someone wants current space-related material in one place and not much else. NASA sits above generic science-news apps because the brand is the actual source, and that is the part of the appeal that keeps it steady.
