ARISS Contact Applications (United States)

?

The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew member on board the ISS. ARISS anticipates that the contact would be
held between July 1, 2021 and December 30,

2021. Crew scheduling and ISS orbits will determine the exact contact dates.
To maximize these radio contact opportunities, ARISS is looking for
organizations that will draw large numbers of participants and integrate the
contact into a well-developed education plan.

?

The deadline to submit a proposal is November 24th, 2020. Proposal
information and more details such as expectations, proposal guidelines and
the proposal form can be found at www.ariss.org. An ARISS Introductory
Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite
link to sign up is: https://ariss-proposal-webinar-fall-2020.eventbrite.com

?

The Opportunity

?

Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.

?

An ARISS contact is a voice-only communication opportunity via Amateur Radio
between astronauts and cosmonauts aboard the space station and classrooms
and communities. ARISS contacts afford education audiences the opportunity
to learn firsthand from astronauts what it is like to live and work in space
and to learn about space research conducted on the ISS. Students also will
have an opportunity to learn about satellite communication, wireless
technology, and radio science.

?

Because of the nature of human spaceflight and the complexity of scheduling
activities aboard the ISS, organizations must demonstrate flexibility to
accommodate changes in dates and times of the radio contact.

?

Amateur Radio organizations around the world with the support of NASA and
space agencies in Russia, Canada, Japan and Europe present educational
organizations with this opportunity. The ham radio organizations? volunteer
efforts provide the equipment and operational support to enable
communication between crew on the ISS and students

around the world using Amateur Radio.

?

Please direct any questions to?ariss.us.education@?????.???.

?

For future proposal information and more details such as expectations,
proposal guidelines and proposal form, and dates and times of Information
Webinars, go to www.ariss.org.

About ARISS:

?

Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS).? In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

So I've had further confirmation that APSS-1 will start transmitting 45
minutes after deployment, and will only beacon every 5 minutes initially.
Still no information on beacon formats.

Interestingly APSS-1 just moved to the 'finished' coordination list:
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=669
I wonder how this got approved so quickly? (and after the original launch
date too...)

I went outside tonight to watch a high pass of the ISS and it was "running
late." About 5-10 minutes. Beautiful pass though.



When I came into the shack to check SatPC32, I discovered the current
download of nasabare keps was dated 11/4.



Apparently the ISS made a maneuver to accept the Dragon capsule and slightly
raised its orbit.



Oh well, it's always fun to watch the ISS go over.

Interesting. It was right on time (visually) here in central Florida. Last
night, too. Even winked out within 5 seconds of prediction. Tracked with ISS
Discovery on iPhone 8, so I have no idea of the Keps date/time. It just does
it by magic.

An interesting (at least to me) addendum to this thread.

An examination of the newly downloaded nasabare keps in use by my SatPC32
showed the date of the current ISS entry to be 11/6/20. Thus not
"up-to-the-second." Ed K9EK's data came from an iPhone app with unknown but
obviously newer data than mine.


Keep that in mind if working the ISS that very new keps are essential as the
ISS does do orbital changes from time to time.

Hey, I'm north of 70; just glad I can still see the moving light anyway! But
we did see the launch from 70 miles away. That's just moving lights, too.
Pretty cool.

About a week ago it was found
<https://community.libre.space/t/tle-issue-satellite-with-old-tles-2020-11-09/
6935>,
as acknowledged on space-track.org, that TLE updates had stopped for a
number of days. Given that this is the core source for most TLE feeds
today, a disruption is to be expected, but we found their feeds had
recovered around Nov 11.

Celestrak and calpoly are both up to date on ISS. AMSAT is the only source
I am aware of associated with nasabare.txt so I will assume that is where
you are pulling from, and the ISS element in that file is definitely behind
(as of this email). I don't know how this file is updated - the delay could
either be coincidental or maybe the upstream issue from a week back has
wedged something in the process?

So, you are right about the orbital adjustments in times like this, but you
are also correct that the TLE is behind as well.

 Hi Ron.

> Apparently the ISS made a maneuver to accept the Dragon capsule and
slightly raised its orbit.

I vaguely remember back in the Salyut 7 and Mir days that an indication the
Russians were about to launch a spacecraft to dock with either of these
space stations was when the the eccentricity of their orbits were brought
closer to zero (a.k.a. "circularized").

Last night's visible pass (based on Keps issues yesterday from Celestrak)
was right on target. PREDICT's eclipse alarm rang EXACTLY when the ISS
entered into eclipse. :-)

It was nice to see Jupiter, Saturn, and the crescent Moon hanging out
together, too. ;-)
