++++++++++++++++
>From AO-40 replacement to US space policy...
The Columbia Accident Investigation Board, (CAIB), determined
that the shuttles were actually experimental vehicles being flown
as if they were operational vehicles. The aging shuttles had so
many design/architectural flaws that they could never be made
"safe" fly. So the correct decision was to retire them.
Sadly, with 6+ years of advance notice the shuttle would retire,
the US currently does not have a way to send astronauts into
space (other than buying seats on the Soyuz).
The history of this predicament is long and tortured, but
essentially comes down to flat budgets. NASA had to
retire the shuttle to free up funds to develop a follow on
vehicle. In the past several years, COTS, Commercial
Off The Shelf, has shown great promise. SpaceX is
probably the closest to having a manned capsule ready.
So, who get credit/blame..? It is said support for the space
program is broad... a mile wide and an inch deep.
Ultimately a disinterested public gets what it deserves.

As someone who has written an introductory article or two myself, I
am inclined to agree. There is a lot of material that shows how easy
it is to work your first satellite, but not a lot of "where to go
from here". What would be nice is a tutorial which starts at working
your first FM sat with a HT and portable antenna, then goes through
from there in stages right through to fully automated stations
capable of working a future HEO or fully automated operation on
pacsats, among other things.

Hi Joe,
Actually, I checked on AO-16 last Saturday. I didn't even get the
transmitter to come on, let alone stay on. It was a low pass, and I hope to
check again in the next few weeks. If you'll remember, the problem with
keeping the satellite ON is temperature related. If it gets lots of sun
(little eclipse), it will be warm enough to remain on. Otherwise, it
won't...and the orbit is such that it doesn't get enough sun--and it
probably won't for another 10 years or so. But I check periodically.
About every week or two Drew KO4MA and I try to turn AO-51 back on. My
latest try was last Saturday. Nothing heard.
IO-26 is still up there, and still humming; it needs to be turned on from
time to time, so I do that. But we haven't figured out how to run it in
voice like we did with AO-16; it doesn't appear possible.
Don't know about AO-10; I haven't listened for a while. And I don't know if
it is expected to come on without commanding (which I cannot do).
73,
Mark N8MH

On a side note. Do we know the 'physical' status of AO-40? Is it still
orbiting the earth? I don't believe I heard anything about it re-entering.
I do remember a conversation here on the BB some time ago about making
an attempt to command AO-40 again to see if it will respond. However,
the command team stated they were reluctant to do so in the event it
might cause further harm to an already bad situation.
My comment would be that if this were the case what can we lose since
we've gone this long without having its access. I think that if there is
even a 1 percent chance of commanding it, it should be attempted since
we've nothing to lose. Again, I may be in left field and missed
something here, but I feel if there is a chance, it should be given a
shot. If things go wrong, we're not any worse off then we have been
without it being operational so long. Then again the command team may
have already made an attempt and my comments are mute.

Graham,
What's 'medium resolution' ? Standard SSTV is not digital, it's analogous
with the (now no longer used) analogue TV. There is true digital SSTV used
on 80m and 40m and (I guess) other bands, from memory this is EasyPal; to
implement this in a satellite would be a long and tedious task.
Implementing one of the analogue SSTV modes would be easier - much easier -
but quality is nowhere as good.

We are looking for a practical system to use on a 1U, or perhaps 2U, cubesat
to take medium definition images and transmit them to the ground on VHF for
educational outreach purposes.

What more harm could there be?
From what I have read, every attempt has already be made.
It's my understanding that AO40 is dead.
If anyone knows for sure please speak up, many would appreciate
information.

Hello Everyone,
Here is some good news that is best shared immediately:
AMSAT President Barry Baines, WD4ASW TV Interview on HAMRADIONOW.tv
Gary Pearce, KN4AQ, producer and host of the HAMRADIONOW.tv webcasts
interviewed AMSAT President Barry Baines, WD4ASW at the Shelby North
Carolina Hamfest. Barry's interview provides an in-depth update on
AMSAT activities and plans.
As Gary says, "So there's a lot going on at AMSAT. Exciting stuff
like commanding a remote-control vehicle with instructions relayed
through the ISS (think Mars Curiosity Rover)". As Barry said, "This
isn't your grandfather's AMSAT" anymore.
Barry discussed AMSAT's exciting projects including:
+ Project Fox Cubesat development
+ AMSAT selection for NASA's ELaNa launch program
+ AMSAT development of missions meeting STEM educational goals
+ AMSAT-ARRL-ARISS teamwork
+ Future opportunities in space
+ How you can join and help

Just heard ISS back on 145.825.
Two students went outside with a D7 HT and sent themselves email using
APRS via ISS. Came back inside and were amazed to see the Email in their

Now they understand APRS!

It must be nice to work the ISS with a handie. I suppose it helps being
so far south.
