Friday,March 4th, a Windows Phone 7 device called "ASTRA 7" took a 90mph ride on a balloon to an altitude of 18,237 meters (over 60,000 feet).
ASTRA 7 was designed to demonstrate the feasibility of using a low-powered, lightweight commodity device (a WP7) as a data logger, communications link and a portal to high performance computing resources in the cloud (through Windows Azure).
ASTRA 7 reached a maximum altitude of 18,237 meters during its 1h 16' flight. The Segoz Logger app running on the WP7 operated, as designed, throughout the flight, providing location notifications to Windows Azure when in GSM range (with the Azure worker re-computing the forecast landing site each time).
The maximum speed reached by ASTRA 7 was around 90mph, logged at an altitude of 10.1km, as the balloon-borne flight train was traversing the jet stream. ASTRA 7 landed 46.6 miles downrange (very close to the pre-flight prediction based on the ASTRA balloon flight simulation model of 47.7 miles).
ASTRA 7 also took over 1200 photos during its flight (one of which is shown below).
