I listened to the Robinson contact via the IRLP Discovery Reflector on the
Internet on the 25th. Several of the other ARISS mentors also listened in.
Nancy WH6PN did her normal outstanding job. At our weekly telecon meeting
later that same day we did discuss the audio levels and time delays; something
we always discuss after a telebridge contact.
For this contact there was a delay of about 5.5 to 6 minutes between real
time and when it came across the Internet. So if one was listening only at the
real time AOS and gave up after a minute or 2; then you would have missed
the contact. There is always about a 5 minute delay of the audio when it comes
across the Internet. I believe that if you are listening in on an IRLP
repeater that the audio is delayed only a few seconds.
At the moment we have had 350 successful contacts. I believe we have had 3
contacts that were deemed outright failures. We have had I think 2 or 3 that
were considered failures on the scheduled contact day but were rescheduled
and were successful on the 2nd attempt. ARISS says congratulations to all of
the school groups and hams around the world who have made that happen. Often
times, that is the first satellite contact for the hams.
When Kenneth or I post the ARISS announcements, we do try to indicate if
Echolink or IRLP will be included but often times it is a last minute decision.
If it is a telebridge contact, then the odds are pretty high that it will be
on one or both. If it is a direct contact, then it is up to the ham group
doing the contact to decide if they want to feed audio to IRLP, Echolink, or
to their own webpage as it is an extra burden on them. ARISS does not require
a group to do a simulcast but does encourage it. If we know it might
happen, then I usually indicate "watch". If we know it is going to happen, the I
usually indicate "should be" or something along those lines.
As far as NASA TV providing coverage, we have been told to not expect it and
not to ask for it. Remember ARISS is a guest on the ISS and we don't want
to wear out our welcome. So ARISS does not request coverage. If on the oft
chance that a camera does show an ARISS contact in progress, then consider it
Hope this helps. ARISS encourages everyone to find a school, fill out the
application, and get on the waiting list. I think you will find it a great
experience. Think of it as your most tension filled Field Day that you will
ever do. Plan on anywhere from 500 to 700 people hours; all of this for a 10
minute contact that the kids (and parents too) will remember for a long long

This is a very interesting comment from the JSC Public Affairs Office. As a
NASA employee and the ARISS Chair, I will make sure we get this comment
clarified. This sounds very strange and out of character from our dealings
with the NASA Public Affairs Office. It may be one person's misperceptions,
which needs to be clarified.
You all probably know this, but the ARISS success rate with schools is well
over 90%, so reliability is not an issue. That is why we have mentors
working with each school.
Now, WRT the IRLP and echolink, I cannot answer that right this moment as I
was not on the Operations teleconference last week, so I did not hear what
happened. Kenneth Ransom and Charlie Sufana follow this reflector pretty
closely and I am sure they will speak up before I get the info and get it in
an e-mail. But we will provide details on this for you and those on bb
I thank you for your sincere interest in the ARISS program. And your
interest in inspiring students to pursue careers in science and engineering.
And to pursue the amateur radio hobby.

First post, so I hope it works.
Here is reply from NASA (and my original)
Dear Mr. Muir:
Thank you for your note. We are sorry about your disappointment.
Speaking just of NASA TV, we do not carry Ham radio events because of
We wish we could offer you better news. We appreciate your interest in

Greetings from 'Down Under' (KiwiSat land)
A golden opportunity lost!
ARISS had scheduled a contact with Robinson Elementary School,
Texas via telebridge WH6PN in Hawaii on 25 Jun 2008 at 15:45 UTC. At
time ISS _was_ over Hawaii, and ISS was scheduled to be in its Live
There was NO audio from the telebrige WH6PN on either Echolink or the
Discovery Reflector, and NASA TV's 'live coverage' segment made
mention of the event - in fact, no 'on-board' coverage was shown at all!
was out of range of TDRSS earlier, but would surely have been back in
by then? A camera at the ARISS position should have been easy to
even if there is not one already present in that segment.
What happened? Was there some other pressing event that could not be
re-scheduled? A technical fault (though nothing was mentioned of such)?
Did 'dirtside' cancel at the last minute? All Internet links showed the
event would run as advertised right up to time.
Echolink *AMSAT* Conference gives feedback on who is connected, and I
observed 6 other stations on at that time (incidentally 3:45 AM next
here in New Zealand). That is 6 parents or grandparents (like me) keen
demonstrate live one-on-one communications with an Astronaut IN SPACE,
are now extremely disappointed. For myself, it was my first attempt at
a conference, and I am _really_ glad I tried solo without getting 3
out of bed.
Despite this disappointment, I will try again (solo), and given at
_some_ measure of success am likely to bring said children and perhaps
to witness the event some time in the future. THESE are your REAL
the Astronauts, Scientists and Engineers of the future!

Is this really a reliability issue, or somebody so high they don't smell
very nice (thinking more govt than anything else) deciding that Amateur =
Ham-fisted, and not realising that the 'Hams' involved are mostly
professionals and, because they LOVE what they do (the original meaning,
Latin), make professional-level efforts to DO IT RIGHT.
Besides, the exercise is NOT 'Carrying Ham radio events', but more an
of continuing existing coverage, in similar manner to one of the Astronauts
doing a video-tour of the premises (which they do from time to time). As I
had pointed out, there is probably a camera already there - the 'Ham Shack'
is in or near the 'Kitchen' area, which has been 'vid-casted' before.
Can we do better? Can we pressure someone/somewhere to not let this sort
of opportunity pass again?
BTW - what DID happen? Anyone?
