International Space Station Astronauts are Calling CQ Students
ARISS-US program?s education proposal window is open April 1 - May 15, 2019
?
March 24, 2019:? The Amateur Radio on the International Space Station
(ARISS) program is seeking proposals beginning April 1, 2019, from US
schools, museums, science centers and community youth organizations (working
individually or together) to host radio contacts with an orbiting crew
member aboard the International Space Station (ISS) between January 1, 2020
and June 30, 2020.
?
Each year, ARISS provides tens of thousands of students with learning
opportunities about space technologies, communications, and much more
through the exploration of Amateur Radio and space. The ARISS program
connects students to astronauts on the ISS through a partnership between
NASA, the Radio Amateur Satellite Corporation, the American Radio Relay
League, other Amateur Radio global organizations and the worldwide space
agencies. The program?s goal is to inspire students to pursue interests and
careers in science, technology, engineering, and mathematics (STEM) and in
Amateur Radio.
?
Educators report regularly that student participation in the ARISS program
stimulates interest in STEM subjects and STEM careers. One educator wrote,
?Many of the middle school students who took part in and attended the ARISS
contact have selected science courses in high school as a result of that
contact.?? Educators are setting up ham radio clubs in schools and learning
centers because of students? interest.
?
ARISS is looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed, exciting
education plan. Students can learn about satellite communications, wireless
technology, science research conducted on the ISS, radio science, and other
STEM subjects. Students learn to use Amateur Radio to talk directly to an
astronaut and ask their STEM-related questions. ARISS will help educational
organizations locate Amateur Radio groups who can assist with equipment for
a once-in-a-lifetime opportunity for students.
?
The proposal window opens April 1, 2019 and the proposal deadline is May 15,
2019. For proposal guidelines and forms and more details, go to:
http://ariss-proposal-webinar-spring-2019.eventbrite.com
Proposal webinars for guidance and getting questions answered will be
offered April 11, 2019 at 7 pm Eastern Time and April 16, 2019 at 9 pm
Eastern Time. Advance registration is necessary. To sign up, go to

Regarding AlSat 1 and its APRS payload, I thought that 145.825 MHz was the
accepted frequency for all APRS on satellites. So I'm curious how that
qualifies as not coordinated if they're following established procedure?
Thanks in advance for any additional knowledge you can share,

Thanks Devin for sharing your thoughts and I agree that 145.825 is the
designated freq for APRS satellites but as per procedure we had some
constraints on the API submission which is a prerequisite for submission to
IARU for frequency co ordination. I have notified? IARU prior to the launch?
that AISAT-1 will use 145.825 as this is a dedicated? APRS payload. We will
ensure the process are followed in the future and to role model such
submissions.?

Subject: [amsat-bb] Upcoming ARISS contact with 58th Hamilton Scout
Group, Stoney Creek, Ontario, Canada
Message-ID: <C777ADB4DA9D45CD9F4D4082B3B8F769@???>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at 58th Hamilton Scout Group, Stoney Creek, Ontario, Canada on
06 Apr. The event is scheduled to begin at approximately 18:31UTC. The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between NA1SS and VE3DC. The contact should be
audible over Ontario, Canada and adjacent areas. Interested parties are
invited to listen in on the 145.80 MHz downlink. The contact is expected to
be conducted in English.
The 58th Hamilton Scout Group, located in Hamilton, Ontario, Canada,
provides youth across genders aged 5 to 26 the opportunity to participate in
educational activities in keeping with the `Canadian Path' program
established by Scouts Canada. The `Canadian Path' encourages curiosity and
imagination by encouraging youth to pursue their individual interests and
skills within a program structure unique to the Scout movement. The
`Canadian Path' also lays strong emphasis on Science, Engineering,
Technology and Math (STEM) activities. The radio contact with astronaut St.
Jacques aboard the ISS will therefore help us further our educational
mandate, as it relates to Scouts Canada's STEM emphasis.
Participants will ask as many of the following questions as time allows:
1. When did you realize you wanted to be involved in the space program, and
what did you do to give yourself the opportunities to get there?
2. What does the earth look like from space?
3. Why do you float in space?
4. How do you eat in space?
5. Have you ever experienced any space sickness and what do you do to
overcome it?
6. What science experiments are you doing on the ISS right now?
7. What do you do for fun in space?
8. How often do you put on your spacesuit and is it comfortable to wear?
9. How do you communicate with others on the ISS who speak different
languages?
10. Do you use boosters to move around the outside of the station?
11. How do you get a steady supply of goods to the ISS, when you are up there
for so long?
12. What is the best part of being in space?
13. What would happen if a meteorite hit the Space Station?
14. How does the spaceship fly without rocket boosters in space?
15. What happens if you shoot a gun in space?
16. How do you sneeze in space?
17. How do you do your laundry on the ISS?

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 Center for the Advancement of Science in
Space (CASIS) and National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,

Hello all,
I downloaded the software (V0.21) from the G0KLA website, running it on
Linux (Kubuntu 18.04 with Java version 0.64). Well, I'm trying to run
it, because I get the following error message.....
java -jar PacSatGround.jar
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
??????? at PacSatGround.main(PacSatGround.java:29)
On my laptop it runs fine, albeit it uses a slightly older Java version
(0.59) on Debian Testing from 18.03 (Netrunner).
Question: is there a specific Java version that has to be used with
V0.21 of? the PacSat software, or is my system messed up and I need to
do a fresh install?
Cheers,
Hans
