Perhaps, for some reason, the incident was couldn't be publicized until now.
Also, in several of the space-related newsfeeds that I monitor, there

Hi!
I will have an AMSAT table at the Cochise Amateur Radio Association's
Larry Warren Hamfest in Sierra Vista AZ this Saturday (4 May). The
hamfest starts at 0700 local time (1400 UTC), running until the prize
drawing at noon (1900 UTC). The hamfest is at the club's Green Acres
Field, east of S
Um, the dates in the article are from 2012 (that be last year).
Interesting stuff, but why is NASA posting it now?

I'll throw this one out there though I'm sure some of you already know
about it. "Rocket Propulsion Elements" is a pretty good book on the basics
of rocket propulsion. I've dabbled in it a few times but do plan on a more
comprehensive study (I'm an EE and actual coursework takes precedence over

Yeah, but the control, er safety, folks won't give us enough "mass out

more outside the box thinking...you have a gun (of sorts) on the satellite.
Then fire to the rear forcing the little satellite faster in the opposite
direction. We could select from .22LR to 45 ACP. I realize the anti gun folks
would go bizerk. Back in my corner now.

Thinking way outside the box, what about some sort of phased array using
dipoles, which has the boresight synthesized to point at earth. In other

phase of the antennas so that earth is in focus.

Yes MEO would be good. It should be possible to improve the signal levels while
keeping omni-directional antennas on the satellite by us
