Hi, Doug. Welcome to the satellites and congratulations on your first
satellite QSO!?
This is the right email group for any questions you have. It's just a little
weird right now because there is a contested board of directors election
going on.
So ask those questions!!
If you have already located these sources of info, my apologies for telling
you stuff you may already know, but I generally check out these three
webpages for info:
https://www.amsat.org/two-way-satellites/
https://www.amsat.org/status/
https://www.amsat.org/track/index.php
Other folks on this list will have their favorite sources of info that they
will share also. There are lots of folks on this list with much greater
technical know-how than I and they will be happy to answer your questions
(I'm happy to answer them, too, if I can!).
Hope to catch you on a bird very soon!

Subject: [amsat-bb] Brand new to satellite
Hello all,
I am brand new to satellite, and actually made my first QSO this morning on
AO-91. I found this email group in the AMSAT Getting Started With Amateur
Satellites 2020 which I purchased on a recommendation.
Is this the informational email group? (I also signed up for the New
England mailing list, but it looks like there hasn't been any activity
since 2013) I am of course looking for all the information I can find, but
this group seems to be more of a political discussion. Please point me in
the right direction.
Thanks!

A few other places to get information, Twitter and there is a newish

Michelle,
I am kind of surprised that AMSAT-BB is the first time I have heard about a
design review that could impact the AREx design for the Lunar Gateway SDR.
As I stated in the AREx meetings, I want to ensure we have a host of
independent space experts that are pre-selected and vetted for all our
design reviews. This has not been done yet. And it will be an essential
element for AREx to move forward on our Lunar Gateway payload with the space
agencies.
This design review has not been communicated to the AREx team. We
absolutely need to have open and full team communication on all design
developments to ensure AREx mission success. Not communication to AMSAT-BB,
where only a small segment of the AREx team is a part of.
As the acting Program Manager for the AREx Lunar Gateway initiative, I would
appreciate you letting us know ahead of time of any planning for design
reviews as well as any planned meetings that can affect the AREx system
design. If I remember correctly, I was expecting a plan from each team on
their efforts to evolve their systems over the next several months. This is
a critical first step. We also need to get a handle on who all is on this
team so that we can ensure that there is open, effective and impactful
communication across the team and the subsystems.
I would appreciate your attention on this matter.
Thanks,
Frank

Greetings all!
A design review workshop has been scheduled for 7am Pacific 30 July 2020 for
the 6U digital multiplexing transponder from Open Research Institute.
This work is made available for free to the general public and assumes AMSAT
as the primary audience and beneficiary.
The design is the same as one in progress for AREx (AMSAT/ARISS USA). The
design review will be of direct benefit to AREx and meets their requirements.
The design is under consideration for other missions.
If you would like to participate in the design review workshop, then please
write me at w5nyv@????.??? for a Zoom invite.
The communications functions and circuits are the focus of this review.

I apologize for the misunderstanding. Entirely my fault.
There was very strong support for the architecture at the ARISS hardware
summit last month. This workshop review is intended to honor that approval
and support, and pay it back with interest, not to upset it in any way.
Reviewing the systems architecture (to be ready for a PDR originally
scheduled for August) was discussed in a recent call, along with
recruitment from wider communities. This seemed to get a green light.
A review was discussed in the systems engineering splinter group with
strong support.
I have complied with a request to get the right communications support (GTM
vs Zoom), which is greatly appreciated feedback.
Having a workshop review was not perceived as controversial during that
conversation, or I would have not proceeded.
With schedule and staffing identified at the highest risk level (severely
high!) I?m very motivated to reduce that risk for you, however I can. The
more people that review everything we have for architecture, as soon as
possible, the better.
The impact is intended to be more and better choices for widest possible
use, as soon as possible, no strings attached. The only people restricted
are those that implement any provisional design. All know it is subject to
change and high risk.
What things would you like me to do in order to satisfy all your concerns?

For sure lots of junk out there, and likely some in "HEO" but more
likely really GTO that's left over from getting things up there.
Leftover junk takes a pass at the Foxes frequently, which makes me
wonder who the space junk really is when people claim that's what our
CubeSats are.? Don't mention -Cliff I still haven't finished a failure
analysis (mostly because Spaceflight and SpaceX aren't talking).
So was it moving in a generally north-south way, or more of an east-west
lower latitude way?
And I'll take the opportunity to plug my favorite Android app Heavens
Above Pro which would tell us right at the time but then you lose the
fun of speculating and bonding over satellite stuff (before you give up
and look it up).??? hihi

It's always fun to watch the skies just after sunset or right
before sunrise while it's still dark. Lots of things in orbit
can be seen while they are still in sunlight.
Don't know if you can see a HEO with the naked eye unless it's
fairly large.

Not all comet watchers enjoy seeing man made objects apparently. This
