Tribune Story about Gil Moore and his POPACS Spheres
Hello All, I don't know if anyone is interested, but there was a story on the Tribune website about some satellites that Gil Moore recently managed to get launched. They are known as POPACS Spheres, and they are being used to study the effect of solar events on the density of the upper atmosphere. I have been helping to identify and track the objects with my scope, with some much-appreciated help from Patrick.

Tyler, Gil is truly one of the greats! One of my most treasured memories with him is when he introduced me to an old fellow who had worked with Robert Goddard, and I did an article.

Nice work Tyler. And I was impressed that the reporter used modern units of measure almost entirely. I see they carry IDs 39268, 39269 and 39270. Is that correct? Are those for POPACS-1, POPACS-2 and POPACS-3 respectively? patrick On 23 Oct 2013, at 23:18, Tyler Allred wrote:

Patrick, I am not sure about the IDs. Where are those numbers coming from? I have been downloading the TLEs from Celestrak under the "Last 30 days Launches" heading, where they are now just listed as POPACS 1, 2 and 3. They will drop off that list soon however because they were launched on September 29th.

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? patrick On 23 Oct 2013, at 23:54, Tyler Allred 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.

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:

All, I made is short movie animation of one of my tracking runs on POPACS-3. It isn't too exciting, but someone might be interested. These things are moving pretty fast... orbiting in roughly 100 minutes. http://www.allred-astro.com/misc/POPACS-3v3.wmv Cheers, Tyler -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Tyler Allred Sent: Wednesday, October 23, 2013 11:18 PM To: utah-astronomy@mailman.xmission.com Subject: [Utah-astronomy] Tribune Story about Gil Moore and his POPACS Spheres Hello All, I don't know if anyone is interested, but there was a story on the Tribune website about some satellites that Gil Moore recently managed to get launched.
