Frequently Asked Questions About ARISS

WHAT IS ARISS?

This program is an opportunity for students to experience the excitement of Amateur Radio by talking directly with crewmembers of the ISS (International Space Station). Teachers, parents and communities will see how Amateur Radio can energize youngsters about science, technology, and learning.
Speaking to the ISS crewmembers is a unique educational experience. NASA would like to take this opportunity to involve large numbers of individuals, particularly youth, in technology and the US space program with the help of Amateur Radio.

WHO SPONSORS ARISS?

The American Radio Relay League (ARRL), the Radio Amateur Satellite Corporation (AMSAT) and NASA sponsor these exciting experiments. AMSAT volunteers support technical operations, and mentor school groups. ARRL provides ARISS information. ARRL and NASA HQ create and distribute ARISS lesson plans and resources for teachers. The Federal Communications Commission supports ARISS.
Hundreds of Amateur Radio operators, including those from NASA Amateur Radio clubs at Johnson Space Center, Goddard Space Flight Center, and Marshall Space Flight Center, work behind the scenes to make these educational experiences possible.

HOW CAN I -- A TEACHER -- GET STARTED IN ARISS?

All schools, including the eight ISS partner countries are required to submit an ARISS application and an "Educational Proposal." Applications are available from ARRL or on the web at http://www.arrl.org/ARISS/ariss-ap.html
Schools from the USA and the eight ISS partner countries are selected for contacts from these applications. (Currently we have about 40 schools waiting for a contact.)
Scheduled contacts give the schools a 95% chance at a successful contact. Ten or more students at each school ask the ISS crew questions, and the nature of these contacts embodies the primary goal of ARISS--to excite student interest in learning.
The normal wait for a contact is 2 years. Until your school contact has been scheduled, your classes can participate by eavesdropping, or by trying to make a random contact with the astronauts. Imagine listening in on the ISS crew from your classroom.
ARISS lesson plans are available from ARRL or you can download them now from http://spacelink.nasa.gov/Instructional.Materials/NASA.Educational.Products/Amateur.Radio.in.Space/
If you are a schoolteacher, but are unfamiliar with ham radio, you can still take part in ARISS. Visit http://www.arrl.org/field/club/clubsearch.phtml to find a list of local Amateur Radio clubs to ask for assistance.
If you are a parent, grandparent and/or a ham radio operator, contact ARRL F&ES and a local school. F&ES will send materials, including ways to convince teachers and school administrators that Amateur Radio is an important discipline the school should take advantage of on a full-time basis. This is a tremendous opportunity for you to showcase ARISS and Amateur Radio to students of all ages.

HOW DO I APPLY FOR A SCHOOL RADIO CONTACT?

If your school is interested in ARISS, you must complete an application and write an Educational Proposal. ARRL collects these for the ARISS Selection Committee who makes the final selection with input from the ISS crew. All grade levels and type of schools (rural, suburban and particularly urban) are encouraged to apply.
ARISS school applications are available at http://www.arrl.org/ARISS/ariss-ap.html, or email your request for an electronic version to: ariss@arrl.org . An Educational Proposal must accompany all completed applications. Your proposal should include answer questions like:
1) How will you:
a) integrate this activity into the school curriculum and
b) involve as many grade levels as you can, participating through essay contests, poster drawing, letter writing, etc.?
2) Do you have an experienced group of hams to assist in setting up all necessary Amateur Radio equipment and antennas
3) How will you get as much media coverage as possible?

HOW WILL I KNOW IF MY SCHOOL IS SELECTED FOR A CONTACT?

Schools that have been selected for ARISS scheduled contacts are contacted by a "ARISS coordinator." NASA requires selections to be made several months in advance. If a school is not chosen, its application is recycled for future use. Schools typically wait one year or longer.

I AM A HAM. HOW CAN I INTRODUCE ARISS TO MY CHILD?

Bring a shortwave receiver to school and let students eavesdrop on Amateur Radio retransmissions. Then set up a 2-meter satellite ground station in class, and try a satellite contact. The teacher can apply for a future school contact, almost guaranteeing that students will have an opportunity to communicate with a crew.

CAN HAMS MAKE AN UNSCHEDULED ARISS CONTACT?

Yes. The ISS crew has not lost sight of why ARISS has been so successful. It is the Amateur Radio community that has brought astronauts voices into schools. Crew members make random contacts with earth-bound hams. They make contacts during their breaks, pre-sleep time and before and after meal-time. Astronauts have contacted thousands of hams around the world. Computer software allows the crew to operate the 2-meter packet gear radio in unattended mode, and hams can make contacts when the crewmembers are working.

WHAT TYPE RADIO DO I NEED?

A typical ARISS ground station includes a 2-meter FM transceiver and 25-100 watts of output power. A circularly polarized crossed-Yagi antenna capable of being pointed in both azimuth (N-S-E-W) and elevation (degrees above the horizon) is desirable. But successful contacts have even been made with verticals and ground plane antennas. Commercial and public domain software is available to help track when a shuttle or ISS will be in range of your station, and where to point your antenna. For more details on assembling your satellite/ARISS station, get the Satellite Handbook from ARRL (see last section).

HOW DO I TALK TO THE ISS CREW?

You may communicate with the crew using voice, packet (computer) radio or television. It all depends on what equipment the crew has in space. Astronauts aboard the Space Shuttle Columbia in 1996 made hundreds of random voice contacts with ham radio operators. When the astronauts were busy with other activities, a computerized ham station aboard the orbiting shuttle automatically made contact with thousands more hams.

WHAT ARE MY CHANCES OF MAKING A RANDOM CONTACT?

At ISS, the work schedules of the crew dictate when they can operate the radios. So most of the general contacts they make are random.
The ARISS Working Group recognizes the long-standing commitment of the ham radio community in supporting ARISS, and asks the crew to do as many general ham contacts as possible.

WHAT ARE ARISS RADIO FREQUENCIES?

The following VHF frequencies are used for some ARISS contacts. These frequencies were chosen after much deliberation, to minimize problems between ARISS and other 2-meter users. If you have comments, please direct them to AMSAT via Frank Bauer, KA3HDO, at his address in the Radio Amateur Callbook or email ka3hdo@amsat.org or ARRL F&ES. We appreciate the cooperation of all amateurs in making ARISS successful.

Frequencies used for ARISS
Voice Downlink:
145.80 MHz (Worldwide)
Voice Uplink:
144.49 MHz(region 2&3),
145.20 MHz(region 1)
Packet Uplink:
145.99 Mhz (Worldwide)

Most ARISS operations are split-frequency (everyone uses separate receive and transmit frequencies). Please do not transmit on the shuttle's downlink frequency. The downlink is your receiving frequency. The uplink is your transmitting frequency. Earth stations should listen to the downlink frequency and transmit on the uplink frequency only when ISS or the spacecraft is in range and the astronauts are on the air.

CAN I USE MY SHORTWAVE RADIO TO EAVESDROP ON THE CREW?

Goddard Amateur Radio Club (MD) will often re-transmit live, NASA air-to-ground audio over Amateur Radio frequencies from their club station, call sign WA3NAN. This station, and some VHF and UHF repeater groups, provide this service so amateurs and students can hear the educational communications. You will hear the astronauts, Mission Control, and bulletins about ARISS activities. WA3NAN operates on the high frequency (HF) bands at 3.86, 7.185, 14.295, 21.395, and 28.65 MHz and in the Greenbelt, MD area on VHF at 147.45 MHz (FM).

CAN I RE-TRANSMIT COMMUNICATIONS ON THE HAM FREQUENCIES

FCC rules, Part 97.113 (e) , state that hams are permitted to retransmit shuttle air-to-ground communications, provided that approval has been obtained from NASA. In 1990, ARRL sought NASA's permission, on behalf of radio amateurs, to retransmit communications. NASA Public Affairs Office encouraged such retransmissions, indicating that the communications are public domain.
Please follow these guidelines if you plan to rebroadcast NASA shuttle communications,
1) In keeping with good amateur practice and FCC rules, retransmissions should be limited to educational missions.
2) Retransmissions should be done manually (with a control operator present).
3) NASA audio contains crew "wake-up music." Amateurs should avoid, if at all possible, retransmitting music or other prohibited transmissions listed by the FCC rules (Part 97.113).

HOW CAN I TRACK SPACECRAFT WITH A COMPUTER?

Software is available for tracking spacecraft with a personal computer. Here are some options (ARRL in no way warrants these products or services):

AMSAT TRACKING PROGRAMS:

WHAT ARE "KEPS?"

Spacecraft-tracking software uses "Keps" or Keplerian elements (also known as "orbital" or "tracking" elements) to pinpoint the location of a spacecraft. Keps provide the software with a spacecraft's orbital track, which the computer uses to calculate its location. Using a tracking program tells an observer when a spacecraft will appear above his or her horizon.

WHERE CAN I FIND KEPS?

Keplerian elements are available from:
AMSAT News Service publishes weekly information bulletins including Keps. These bulletins are distributed electronically through amateur packet radio networks, landline networks and the World Wide Web http://www.amsat.org
AMSAT also has email mailing lists to deliver Keps. To subscribe, send a message with your request to listserv@amsat.org Include your call sign (if any), your email address, and the names (shown below) of the mailing lists you wish to receive:

HOW DO I GET AN ARISS QSL?

QSL cards are similar to postcards. Hams exchange QSLs to confirm their radio contacts with other stations. Participating in ARISS is an exhilarating experience. But waiting for that coveted QSL card requires patience. Designing a card for the ultimate DXpedition is a lengthy process. Once the cards are printed, RAC forwards them to the Amateur Radio club managing the QSLs.
Send your QSL cards or reports to one of the following addresses.

For the USA :
