ARISS School Proposal Window, for US, Remains Open Through April 15

February 17, 2015 - ARISS is now accepting proposals for U.S. schools
wishing to schedule contacts between their students and the
International Space Station for the next cycle. Details on
submitting proposals can be found below in the attached ARRL News

Message to US Educators

Amateur Radio on the International Space Station

Contact Opportunity

Call for Proposals
Proposal Window February 15 - April 15, 2015

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 *January 1, 2016 and June 30,
2016*. 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 April 15, 2015.
Proposal information and documents can be found at

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 and educators
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 contact dates and times.

Amateur Radio organizations around the world, NASA, and space
agencies in Russia, Canada, Japan and Europe sponsor this educational
opportunity by providing the equipment and operational support to
enable direct communication between crew on the ISS and students
around the world via Amateur Radio. In the US, the program is managed
by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American
Radio Relay League) in partnership with NASA.

More Information

Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.

For proposal information and more details such as expectations,
proposal guidelines and proposal form, and dates and times of
Information Sessions go to www.arrl.org/hosting-an-ariss-contact.

Information Sessions are available for those wishing to obtain
more information or to ask questions about the ARISS Proposal
process. Upcoming sessions will be held Monday March 16 at 7pm EDT
and Thursday March 26 at 4pm EDT. Those interested in attending one
of these sessions should send email to ariss at arrl dot org to
request login information.

Please direct any questions to ariss at arrl dot org.

$50SAT/MO-76: 15 months, 15 orbits per day, and some unexpected

Saturday, February 21, 2015 marked the 15 month anniversary of the
launch of $50SAT/MO-76, and you guessed it - it is still operating.

Thursday, February 12, 2015 marked a different milestone - its orbit
has decayed to the point where its mean motion crossed the 15 orbits
per day threshold.  The TLEs from Saturday, February 21, 2015
indicate it is now at 15.00521293 orbits per day.

Some people noticed that something odd started happening on Monday,
February 23, and Tuesday, February 24. The $50SAT/MO-76 team noticed
the same thing - during daytime passes in the northern hemisphere,
$50SAT was transmitting once per minute, always sending telemetry in
RTTY format, but never sending GFSK telemetry packets.  Moreover, the
total reset count kept going up by one each time.

The link below will list all the RTTY telemetry messages (of which
the $50SAT/MO-76 team are aware) gathered on February 23 and 24:


What seems to be happening on the decending (daytime) passes is the
CPU is reset just after sending a full RTTY telemetry message, as
here are no GFSK packets sent, but within a half minute the FM Morse
beacon is heard with Stuart's callsign (GW7HPW, the first one in the
rotation).  The teams guess is that the battery voltage is decaying
during the operational cycle, and goes below the 2.9V reset threshold
just after sending the RTTY or just as it is about to send the GFSK
packets.  nce the satellite is able to enable solar power (PCB
temperature >= 0 degrees C), it starts behaving normally; it is now
able to send GFSK packets.  During ascending (nighttime) passes, it
behaves normally, at least here in EN82 land.

There was a brief time where this behavior stopped (2015-02-25,
17:05 UTC through 2015-02-26, 3:47 UTC).  It did, however, start back
up sometime before 2015-02-26, 05:21 UTC, and has continued since.

Why is this happening now?  The team is still investigating, but it is
apparent when looking at the chart of battery voltage over the
lifetime of $50SAT/MO-76 that the battery has suffered a sizeable
drop in capacity.  If the battery voltage under load is dropping
below 2.9V, how is it able to recover back above 3.3 V (the minimum
required to enable transmission) and nearly complete another
operational cycle?  Moreover, why does it always seem to be able to
finish sending an entire RTTY packet before resetting?  In the hopes
of better understanding what is happening, I am in the process of re-
assembling my "BoxSat" test setup in an effort to reproduce on the
ground what is happening in space.  In the meantime, the once-per-
minute transmission is actually convenient from telemetry monitoring
standpoint, as one no longer has to wait 3 minutes for $50SAT/MO-76
to start transmitting.  So, for any of you who have not heard
$50SAT/MO-76, now is the time.  Who knows how long it will continue
to operate in this manner?  Who knows how long it will continue to
operated at all?  Every time an anomaly has occurred and thought,
"this is it - well, it was great while it lasted", $50SAT/MO-76 has
proven to survive. The team hopes that is the case here as well.

The Dropbox has been updated with all the telemetry observations
through (Wednesday, March 4 2015, and can be accessed via the
following URL:


I have also uploaded an MP3 file from the daytime pass over EN82
land on Friday, February 27, 2015 starting at 16:59 UTC (11:59 AM
local time); it can be accessed via the following URL:


During the recording, I switch back and forth between FM and LSB
modes so I can hear the FM Morse beacon as well as the RTTY telemetry.

Please keep the telemetry observations coming, especially now!

$50SAT was a collaborative education project between Professor Bob
Twiggs, KE6QMD, Morehead State University and three other radio
amateurs, Howie DeFelice, AB2S, Michael Kirkhart, KD8QBA, and Stuart
Robinson, GW7HPW. The transmitter power is just 100 mW on 437.505 MHz
(+/-9 kHz Doppler shift) FM CW/RTTY. $50SAT uses the low cost Hope
RFM22B single chip radio and PICAXE 40X2 processor.

There is a discussion group for $50SAT

Double School Contact for Samantha Cristoforetti, IZØUDF

Saturday, March 7, 2015 at 10:51 UTC, 11:51 local time and at 12:29
UTC, 13:29 local time, students at "G. Salvemini - G. La Pira",
Montemurlo, Italy, and "Dante Alighieri" 1st Grade Secondary (Middle)
School, Casale Monferrato, Italy established two ARISS contacts with
ESA astronaut Samantha Cristoforetti, IZØUDF onboard the
International Space Station. These were direct contacts performed by
Amateur radio ground stations IQ5VR, located at "G. Salvemini - G. La
Pira" in Montemurlo and IK1SLD located at "Dante Alighieri" School in
Casale Monferrato.

Presentation G. Salvemini - G. La Pira
The school "Salvemini - La Pira" is in Montemurlo, province of
Prato, Tuscany region and it is a Secondary Middle School; it has 21
classes with pupils aged between 11 and 14. The name of the school
derives from the fusion of the two schools of the commune. This is
the only secondary middle school of the area. The schoolhouse hosts
around 520 pupils.

Presentation "Dante Alighieri"
The "Dante Alighieri" School is situated a bit off the town centre
of Casale Monferrato, near the ancient Cittadella, province of
Alessandria, Piedmont region. It's a modern construction, developed
on two main buildings: one for the school's didactical and
administrative activities, one for the sport activities (gym and
pool). It's surrounded by a wide playground, with a little plantation
of poplars, planted by the pupils of the school. There are 12
classrooms (4 at the main floor and 8 at the first floor) and
different labs: Science lab, Informatics lab, Techno lab, Art lab,
Maths lab, Languages lab and a coloured and wide library. There is
also a lot of afternoon activities, such as Latin courses, Languages
courses and sport tournaments (soccer, basket, volley). The Dante
Secondary I grade School has a current roll of 230 and a teaching
staff of 29. In the last few years the school has been enhanced by
the richness of its diverse student population.

Mentor Francesco De Paolis IK0WGF proposed to the radio coordinators
Mr. Alessandro Tesconi IK5EHI and Mr. Claudio Ariotti IK1SLD to set
up a combined direct  contact, with the support by IK1SLD back-up
ground station and this was accepted. A phone conference call allowed
the full sharing of the events between all the contact sites
involved. The sequence of questions was made alternately by the
students at two schools. ESA astronaut Paolo Nespoli IZ0JPA
participating to the event in the Montemurlo school, presented the
International Space Station, talked about his experience aboard and
before the AOS trained the students for thecontact. Great Paolo!

Contact was established at 10:51 UTC, 11:51 local time with IR0ISS
via IK1SLD and then via IQ5VR, alternately. Mr. Claudio Ariotti
IK1SLD proposed to astronaut continue the contact during the
following orbit. ESA Astronaut Samantha Cristoforetti IZ0UDF agreed.
During the first scheduled contact Cristoforetti answered 10
questions from students. Samantha Cristoforetti was really very
accurate in giving the answers with many details.

At 12:29 UTC, 13:29 local time, contact was established again with
IR0ISS, not on the primary channel, which was interfered, but on a
back-up channel where the event continued normally without problem.
During the second random contact Cristoforetti answered 11 questions
from students and exchanged greetings with the schools. Signals from
the ISS were good during both passes.

Both contacts established with IR0ISS were webcast live on:
http://www.livestream.com/amsat_italia (from Montemurlo)
http://www.livestream.com/ariss (from Casale Monferrato)

The Montemurlo event is available at:

The Casale Monferrato event is available at:

Regional and Local Televisions and newspapers covered the event
also. About 700 students, parents, visitors and media attended the
events at contact sites.

The event was announced on ESA Portal - National News:
(Information is in Italian)
