Watch Bithiri Sathi take selfies in outer space through an app that can be downloaded from Google Play Store. The app has been tried by him successfully. So anyone can do it, Sathi says. There is no need to wear the usual gear of an astronaught. Just follow the directions in the app. The interesting feature has been introduced by National Aeronautic Space Agency (NASA). It is possible to do so through a satellite sent into space by NASA some 15 years ago.
