Water Water Everywhere...on the Moon!

The major space news this past week, and probably most significant in history of space exploration is the discovery of water on Moon!

The international cooperation between Indian Space Research Organization (ISRO) and United States National Aeronautics and Space Administration (NASA) led to this astounding discovery.

The NASA moon minerology mapper instrument onboard ISRO's Chndrayaan-1 moon probe, discovered large quantities of water and hydroxyl molecules on moon. There aren't lakes or puddles (yet) but molecules combined to dust on the lunar surface.

Why is this such a big deal?

Water is important for life (as we know it) to exist.

We already found water ice on places like Mars, why are we excited about Moon?

Moon was supposed to be dry, and after all these years of exploration, including various manned missions, it is hugely surprising that water molecules were not discovered before. This opens up a new set of questions....

  • Where did all these water come from? whats its origin?
  • Why haven't we been able to see it before?
  • What other parts of solar system, which we currently think as dry has water?
  • Is there liquid water on Moon?
  • When are we going to announce that we found life on Moon ? ( :)
These questions will be discussed and debated for years to come...

"WayNotes" Augmented Reality App for Android!

WayNotes is my new experiment with "Augmented Reality".

Its is an app for Android mobile devices, using which users can create notes and post them to geographical locations. Using phone features such as GPS, Camera, Compass, when the user points the phone in the direction of the note, the note appears as a circle shape, in its location overlaid on top of live camera feed.

Also, users will be able to access place names from database.

The app has been submitted for Android Developers Challenge 2

I had submitted this research work for review in ACM multimedia 2009 Grand Challenge contest, Eventhough it was not selected for publication, I got some very good reviews!
