Winners in the ARISSat-1/KEDR Chicken Little Contest

The Chicken Little Contest received 77 entries from 17 different countries, and all continents except Antarctica.

Based on comments sent along with the submissions, a wide variety of techniques were used. These ranged from detailed calculations, to comparisons with past satellites, to guesses based on birthdays.

The winners in each category are:

+ Kindergarten through grade 8:
Cora Haefner, KK4ECV, Fort A.P. Hill, VA, USA

+ High School, grades 9 through 12:
Cameron, Lancashire, UK

+ Adult:
Thomas Frey, HB9SKA, Birr, Switzerland

Cora, KK4ECV and Thomas, HB9SKA were both within 15 hours of the
best data we have from Space Track: approximately 0700 on 4 January 2012, in the South Atlantic.

All three winners have received an appropriate Chicken Little Certificate, and the congratulations of the ARISSat-1/KEDR Team. Thanks go to all those who entered, and especially educators who worked with students.

Winners of the ARISSat-1/KEDR Grab the Last Telemetry Contest.

Thanks to the dedication of stations around the world, a nearly steady stream of digital telemetry reports were received in the final days from ARISSat-1/KEDR:

31 Dec — 1125
01 Jan — 1537
02 Jan — 1541
03 Jan — 1048
04 Jan — 107

Many other reports were received from stations copying the voice, SSTV, and telemetry transmissions, as well as some contacts through the transponder.

The final digital data received was copied by both JA8TCH, Mori Seiji, Sapporo City, Japan, and JA0CAW, Tetsurou Satou, Niigata City, Japan.
It was received at 06:02:14, 4 January, 2012, less than an hour before the estimated point of loss in the South Atlantic.
Their data, combined with the submissions of many others, constitutes the most comprehensive coverage of the reentry of any amateur satellite.

JA8TCH and JA0CAW will receive a certificate for their achievement. They and all who submitted telemetry throughout the ARISSat-1/KEDR mission have the thanks of the entire team.

Deployment of ARISSat-1/KEDR satellite expected August 3

Deployment of ARISSat-1/KEDR satellite expected August 3

After a postponed deployment in February from the International Space Station (ISS), the ARISSat-1/KEDR amateur radio satellite is expected to begin its mission on August 3, 2011. This was the word received from Energia official, Sergey Samburov during an ARISS teleconference on July 19. Deployment of the craft is planned during EVA-29.

NASA TV will cover the EVA live starting at 1400 GMT on August 3.

ARISSat-1/KEDR is a satellite designed and built by amateur radio operators to specifically interest students in scientific and technological careers. Through the use of ham radio equipment, students and teachers should be able to access and utilize the satellite from a classroom environment with minimal set up.

ARISSat-1/KEDR is a cooperative effort between AMSAT, ARISS (Amateur Radio on the International Space Station,) RSC-Energia (The Russian Space Agency) and NASA. The design, development and construction of the satellite was done by AMSAT volunteers. Original plans called for the satellite to be housed inside an old Russian spacesuit, but when the suit became unavailable, a spaceframe was developed to house the radio equipment and solar panels. The new satellite was named ARISSat-1/KEDR. Another name for the spacecraft is RadioSkaf-V. The transmitted callsign will be RS01S.

The mission was specifically designed as an education-based satellite.

Some of its broadcast features include a voice identification, voice, digital and morse code telemetry, stored image and on-board camera transmissions via Slow Scan TV and digital telemetry from a Russian science experiment that will measure vacuum in earth’s lower atmosphere. Other aspects of the mission include CW (Morse code) and voice message contests to interest students in participating along with stored images submitted by students all over the world as part of its payload.

ARISSat-1/KEDR activation planned

ARISSat-1/KEDR Project Manager Gould Smith, WA4SXM said this week the latest status, discussed during the International ARISS teleconference Sergey Samburov, RV3DR announced the ARISSat battery will be charged late July and a test of the system will be conducted on the ISS from 1915 UTC 30 July to about 1200-1400 UTC 31 July.

During the test ARISSat-1 will be in LOW power mode, this means that it will transmit about 40 seconds and then shut down for 2 minutes and then transmit for 40 seconds, etc.
The standard ARISSat-1/KEDR 2m downlink band plan should be
transmitted. Additionally, the FM signal also downlinked on 437.55 MHz.

As to the date of deployment, Gould summarized,
“The deployment date for ARISSat is still subject to change. As of July 14 we are looking at a 3 Aug 2011 date for EVA 29 and the ARISSat-1/KEDR deployment. The ARISSat/KEDR deployment is the first task of the EVA, so it will occur fairly soon after the EVA begins. We will let everyone know more as we know more.”
