Just to make sure I'm understanding this, POPACS 1 is the 2kg, POPACS 2 is the 1.5kg and POPACS 3 is the 1kg. Have I got that right? Thanks, patrick Sent from my iPad On Oct 24, 2013, at 7:38, "Tyler Allred" <tyler@allred-astro.com> wrote:
Patrick, You can tell by the position. The 2kg is in front, the 1.5kg next, and the 1kg last. That is the design of the experiment. Because the shapes are identical and the masses different, the heavier the sphere, the less it is slowed by atmospheric interactions. It is by measuring the differences that the experiment will provide meaningful information about the upper atmospheric density. Cheers, Tyler

I found them on Celestrak's "Master TLE Index": http://www.celestrak.com/NORAD/elements/master.asp
They are listed there at the bottom of the CubeSats section.
They are listed there as POPACS 1, POPACS 2 and POPACS 3 but I can't find which is the 1kg, which is the 1.5kg and which is the 2kg.
Do you know which is which?
