Waste of Tax dollars
akwaman   8/29/2013 3:36:24 PM
This is a project that could have been done by a University, not a serious government program.  Considering we already know how to put cameras in space, this is a waste of effort and tax dollars.  I am ashamed of our government for supporting and funding such a program.  And to think they try to play it off like it only cost 3500 dollars.  What a joke:

1.  We paid people to do this (they could have been doing something useful)

2.  We paid to have a rocket send it to space.

3.  We paid to have a bunch of people involved in the launch and logistics

4.  Does this device even have thrusters to keep it in position, or does it just spin around and take picutures randomly?

5.  What happens when the battery runs out after a few hours, or days.

6.  We all wasted time reading this article and commenting on it.  LOL

Naperlou, bigger is better...but not always.  The Nokia phone was probably not available when the project was put together.  And the more photosites you cram onto a tiny imager the lower the light sensitivity.  That's a big tradeoff.  The available real estate for the imager in a cellular handset is rather small.  If your chassis is a full size DSLR camera or shoulder mounted video camera you have the room for a much larger imager and much large optics.  The photosites can be much larger affording far more photon energy collected per pixel.

Without resorting to a strobe or a puny LED camera light a DSLR can produce excellent photos in light way too dark for a cell phone camera.

While single chip video cameras are becoming more and more popular with some even appearing in professional equipment, the workhorse cameras still utilize three chips for best color rendition and uncompromized sensitivity.

BTW, cell phone imagers are typically CMOS.  The older but still very popular imager technology for professional video is the CCD.  But ironically they often develope hot stuck pixels due to cosmic radiation damage.  How long do you suppose a CCD imager could survive in earth orbit before the imager would be pockmarked with hot pixels?

You know of a university that launches rockets?

I guess someone missed the point.  Let me spell it out for you... This is like a high school project... could be launched into space on someone elses rocket, and:


Cambridge University:


I would research more, but I have wasted enough time on this dribble.

@akwaman: Do you mean to say that its that simple ? Also do you think any other country – rocket will allow an un-authorized device to be plugged in ?

Sigh... I'm sorry a.saji, I don't have time to explain how the world works to you. The only thing simple here, is you.

It was taken by NASA using the little satellite shown in the photos, A Saji.
