基于Windows Phone OS 7.1 Mango开发的探索火星应用程序，通过Dallas平台获取美国NASA 提供的火星探测行动拍摄到的图像数据。Dallas项目（现为Windows Azure Marketplace）是微软提供的数据交易和分享平台,即能够让数据提供商通过Dallas平台公布API使数据消费者以OData协议共享数据。
Microsoft Project Codename “Dallas” changes the way information is exchanged by offering a wide range of content from authoritative commercial & public sources in a single marketplace, making it easier to find and purchase the data that you need to power your applications and analytics.
NASA has hundreds of thousands of images from their missions to Mars. I personally found the image data provided by NASA on the Mars missions interesting and decided it would be cool to create a Windows Phone application that could browse through Mars rover pictures.
