The Express message below was sent to 18,516 EXPRESS subscribers and to 1,285,892 NASA Twitter account subscribers. Using social media services to expand the range for NASA education messages has increased the total audi- ence to approximately 1,304,408 people. (Yes, that's 1.3 million people).
[NASA EXPRESS Message follows]
ARISSat-1 Satellite Launched
A satellite with amateur radio capabilities and a student-designed experiment was released into orbit around Earth on Aug. 3, 2011, during a spacewalk outside the International Space Station. The sat- ellite is transmitting signals containing information that students around the world can access.
ARISSat-1, which stands for Amateur Radio on the International Space Station Satellite-1, contains a student-designed experiment and other equipment that students can use to learn more about space and space exploration. The rectangular spacecraft is covered by six solar panels that will charge the batteries in the satellite for about six months as it orbits Earth. Spoken telemetry values, with data such as temp- erature and battery life, are intended to promote science and mathem- atics education by encouraging school children to listen to the satel- lite, track its progress and plot the changes.
The project website provides free downloadable software that can be used to decode the data. In addition to data, the satellite will trans- mit 24 pre-recorded greetings in 15 different languages -- French, Spanish, German, English and Chinese, to name a few.
Check out the ARISSat-1 website at http://arissat1.org/ for information on data transmissions, contests and student activities.

SB SAT @ AMSAT $ANS-219.03 ARISSat-1/KEDR Deployed on August 3 - Signals Received
AMSAT News Service Bulletin 219.03 From AMSAT HQ SILVER SPRING, MD. August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.03
ARISSat-1/KEDR was deployed from the ISS during EVA-29 on Wednesday, August 3 by Cosmonaut/Flight Engineers Sergei Volkov and Alexander Samokutyaev. First reported signals were received by JR8LWY with copy of the telemetry beacon as the satellite passed over Japan.
Full operational capability of ARISSat-1/KEDR was quickly confirmed after initial concern of a missing or damaged 70cm receiver antenna on the satellite.
145.950 MHz FM Downlink - OPERATIONAL ------------------------------------- FM transmissions will cycle between a voice ID as RS01S, select tele- metry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control.
If you successfully receive the SSTV transmissions, you are invited to upload your picture to to the ARISS SSTV Gallery: http://www.amsat.org/amsat/ariss/SSTV/
435 MHz - 145 MHz Linear Transponder - OPERATIONAL -------------------------------------------------- The linear transponder operates in Mode U/V (70 cm Up, 2m Down). It is an 16 KHz wide inverting passband and the convention will be to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink.
The full status of the 70cm antenna is unknown however reports of contacts and full uplink-downlink operation are being received:
+ Drew, KO4MA reported on August 4, "I was able to hear myself with as little as 1 watt on the 0425Z pass". This equates to an EIRP of as little as 26 watts which can be easily produced by even modest satellite stations. Audio with a picture were posted at: http://www.youtube.com/watch?v=0AFyZNAbOeA
+ John, K8YSE reported completing an unscheduled contact with KD8CAO on August 5 at 1125z. Signals were weak but readable.
+ Masa, JN1GKZ reported from Tokyo receiving his downlink signal during an eclipse pass on August 5, 1233-1240z with a clear and loud downlink though the elevation was less then 5 degrees.
145.919 MHz CW Beacons - OPERATIONAL ------------------------------------ The CW transmissions will be callsign ID RS01S, select telemetry, and callsigns of people actively involved with the ARISS program.
145.920 MHz SSB BPSK-1000 Telemetry - OPERATIONAL ------------------------------------------------- AMSAT needs your telemetry from ARISSat-1/KEDR. Since there are no "Whole Orbit Data" storage mechanisms onboard ARISSat-1/KEDR, your submissions are the only way for AMSAT to collect the spacecraft telemetry and KURSK experiment results.
+ Recorded file ARISSat-1/KEDR and Kursk telemetry CSV files (in the ARISSatTLM folder) can be sent as an e-mail attachment to: [email protected]
+ If you are running ARISSatTLM and receiving the signal "live" from ARISSat-1/KEDR, please enable the telemetry forwarding option.
+ The latest telemetry can be seen LIVE on your computer or cell phone at: http://www.arissattlm.org/mobile

SB SAT @ AMSAT $ANS-219.05 AMSAT-UK Issues ARISSat-1/KEDR BPSK Reception Challenge
AMSAT News Service Bulletin 219.05 From AMSAT HQ SILVER SPRING, MD. August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.05
ARISSat-1 was deployed from the ISS on August 3. It has a composite VHF downlink that will easily fit into the FUNcube Dongle (FCD) re- ceive spectrum. The 145.920 MHz telemetry is 1000 bps BPSK and can, of course, also be received with a normal SSB 2 metre receiver.
The signal levels from ARISSat-1 should be similar to those we expect from the AMSAT-UK FUNcube-1 satellite (and also eventually from UKube-1) and the AMSAT-UK team are keen to discover what will be the minimum and best type of antennas for schools to use with a FUNcube Dongle (FCD) Software Defined Radio (SDR). Therefore user experience with the ARISSat-1 signals will be very valuable in making this determination.
To encourage everyone to receive the 145.920 MHz BPSK ARISSat-1 tele- metry signal AMSAT-UK are offering a FUN reward for listeners!
There are a number of categories for this challenge -they include:
+ The first FCD user, from each continent, who can post a spectrum recording of the received signal together with evidence of decoding the data using the ARISSatTLM software and of sending it to the ARISSat data warehouse.
+ The first non-FCD user, from each continent, who can provide evidence of having decoded the signals and of sending it to the ARISSat data warehouse.
+ The listener, using a FCD or not, who can demonstrate satisfactory reception of the telemetry in the same ways as described above, using the "smallest" possible receive antenna. The actual closing date for this part of the challenge will be announced later.
+ All other entrants who can demonstrate that they have been having FUN!
Please submit your "entries", including your location, station details (including FCD serial number where applicable), postal address and reports to: [email protected]

SB SAT @ AMSAT $ANS-219.06 AMSAT History: 40th Anniversary of First Synchronous Satellite Proposal
AMSAT News Service Bulletin 219.06 From AMSAT HQ SILVER SPRING, MD. August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.06
July 24 marked the 40th anniversary of AMSAT's original SYNCART proposal to NASA, in 1971, to fly a Synchronous Amateur Radio Transponder on NASA's Applications Technology Satellite ATS-G. NASA's response to our proposal appeared to be favorable, but unfortunately NASA cancelled the ATS-G mission.
The SYNCART proposal is on AMSAT-DL's web site at for those who would like to read it. It gives the justification why NASA should fly it for free, listing a number of amateur experiments and applications, most of which would still apply today.
The 1971 WARC on Space Technology was held around the same time (June 7 - July 17, 1971, in Geneva). That's the ITU conference that established the amateur-satellite service and allocated frequencies to it.
Several satellite manufacturers are now advertising that they host pay- loads aboard their satellite platforms. Think how it would transform amateur radio if we could get SYNCART packages aboard one or more of them!

SB SAT @ AMSAT $ANS-219.07 ARISS Status - 1 August 2011
AMSAT News Service Bulletin 219.07 From AMSAT HQ SILVER SPRING, MD. August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.07
1. Successful ARISS Contact with United Space School
On Saturday, July 30 a successful Amateur Radio on the International Space Station (ARISS) contact was held between students at United Space School in Seabrook, Texas and Mike Fossum, KF5AQG on the ISS. Station W6SRJ in California provided the connection. The United Space School is a once a year session of high school students that meets in the NASA/Clear Lake Area. Students come from around the world for a two week session, during which they stay with local host families while being mentored by astronauts, engineers, and scientists to design a mission to Mars as their team project. Class sessions are held at the University of Houston at Clear Lake. Students are given lessons on amateur radio and through the ARISS contact they learn firsthand what spaceflight is like. They will use this knowledge in their team project, which they will present to the Houston space community at the end of their session.
2. Astronaut Training Status
Mike Hopkins, KF5LJG is scheduled for an ARISS Basic Ops class on Monday, August 1. Hopkins is slated to fly with Expedition 37 in September 2013.
3. EE Times Runs ARISSat Blog
EE (Electronic Engineering) Times is running a blog called "Chips in Space - The Building of an Amateur Satellite" that will run over the next few weeks describing how the amateur radio satellite, ARISSat-1 was designed and built. The first entry has been posted: http://www.eetimes.com/electronics-blogs/chips-in-space/4218140/The-Building... an-Amateur-Satellite-1
