Why would I want to develop an app, while I know most of the information of universe without having the knowledge of Science. Our priest taught us all you could for no value and he learnt from his grandfather. Who was born 250 years ago. This knowledge is with us since centuries. Science came up with it like a while ago.
I would love it if there were apps developed for NASA that allowed the public to see what workers on spacecrafts can see if they just look out the window. Just a simple camera feed of what's outside there window any day of the week would be incredible.
