Frequencies have been announced for the new Ham Radio Digital TV transmitter that will send video from the ISS in the amateur radio 2400 MHz band.

The main mission of HamTV is to perform school contacts between the astronauts onboard ISS and the scholarship, not only by voice, but also by unidirectional video from the ISS to the ground within the ARISS program.

In addition to the existing VHF radio amateur station, ISS will host a S-Band video transmitting station. This new equipment can broadcast images from the ISS during the school contacts or other pre-recorded video images up to 24 hours a day to allow ground stations tuning.

It is planned to transmit DVB-S signals on 2.4GHz at either 1.3Msps or 2.3Msps with 10 watts of RF from the ISS Columbus module.

The IARU Amateur Satellite Frequency Coordination Panel have announced frequencies of 2422.0 MHz and 2437.0 MHz.

HamVideo is the name of the onboard DATV S-band transmitter. HamTV is the name of the complete system, comprising DATV downlink and VHF voice uplink. Kaiser Italia SRL was the prime-contractor for the design and development of the flight and ground segment http://www.kayser.it/index.php/exploration-2/ham-tv

It is understood that the HamTV equipment will be carried to the ISS on the Japanese HTV-4 spacecraft currently planned for a launch on August 4.

High School Student’s RocketHub Project

Abby Harrison - Astronaut AbbyFifteen-year-old Abigail Harrison has a big dream, to be the first astronaut to Mars.

She is currently using the crowd funding website RocketHub to raise money to fund a trip to Baikonur in Kazhakstan to watch her mentor, Astronaut Luca Parmitano KF5KDP, blast-off to the International Space Station at the end of May.

Almost two years ago, on the way home from the final launch of STS 134 Endeavour space shuttle, Abby met and interviewed Italian astronaut Luca Parmitanoo. Luca agreed to become her mentor, and for the last couple of years, he has stayed in touch and offered advice.

On Friday, April 26 Abby took part in a Google+ hangout with Luca KF5KDP, she writes:

The interview was facilitated by the Public Insight Network which is a part of American Public Media. I was so excited to have this opportunity with Luca before he launches on May 28, 2013  to live on the International Space Station (ISS) for six months. We had an awesome chat about both of our passions for space and STEM (science, technology, engineering, and math) as well as about Luca’s exciting work on the ISS this year.

We also discussed my exciting opportunity to serve as Luca’s Earth Liaison. In the chat, Luca talked about meeting me for the first time, saying, “I like passionate people. Any kind of passion. Any kind of interest in anything that keeps you inspired…I saw a lot of myself in Abby.” He emphasized his excitement and the importance of my job as Earth Liaison and that he was happy his experience could be used to inspire kids throughout the world.

Thornton Middle School students contact the International Space Station

Thornton Middle School ISS Contact

One of the Thornton Middle School students

On March 25, using the Thornton Middle School Wireless Technology Club callsign KF5NZD, students from Thornton Middle School in Katy, Texas contacted the International Space Station (ISS). They used ham radio to speak to ISS Commander Chris Hadfield VA3OOG who was operating one of the amateur radio stations onboard the ISS, callsign NA1SS.

“NA1SS..NA1SS this is KF5NZD, KF5NZD, How do you copy, over?” called 13-year-old Chris Bobicchio.

The Cypress Creek Mirror reports a long sticky pause filled the room followed by a clear “This is NA1SS to KF5NZD, you are loud and clear, how do you copy me, over?”

Thornton math teacher and ham radio enthusiast Tom Maxwell AE5QB had been trying to get his school involved in the ARISS program for the past three years and was finally accepted last summer.

AMSAT News Service reports Thornton Middle School students, due to their economic backgrounds, have limited opportunities for enrichment activities beyond those that can be implemented in the classroom. Many of its students and families believe that opportunities in high paying STEM careers are beyond the reach of Thornton students, and that, “other kids have all the luck.” This ARISS contact helped dispel these perceptions and will demonstrate to the students and families that Thornton students are capable of complex problem solving, and that they are capable of learning “Rocket Science” material.

Video of ISS amateur radio contact with students at Lycee Polyvalent Anatole France

International Space Station ISS with shuttle Endeavour 2011-05-23A video has been released of the International Space Station (ISS) school contact with participants at the Lycee Polyvalent Anatole France.

The contact took place  at 1142 UT on Saturday, March 9, 2013. ISS Commander Chris Hadfield VA3OOG, used the call sign OR4ISS, and the high school used F4KIS.

Anatole France is a French high school located in Lillers, a small town in the center of the Pas-de-Calais department. There are about 850 students 15 to 20 years old. The science teachers and the local amateur radio club F4KIS, which became in 2010 the ‘Artois Lys Radio Club’, have developed a partnership since 2007 collaborating on projects to send sounding balloons into the stratosphere.

WE-WISH, one five CubeSats deployed from the International Space Station (ISS) on October 4, 2012. burnt up in the Earth’s atmosphere on Monday, March 11. On the AMSAT Bulletin Board Nico Janssen PA0DLO suggested it burnt up at 02:59 UT near 48 degrees North, 119 degrees East. He says TechEdSat is likely to be the next of the five to re-enter sometime in April.

Deployment of CubeSats WE-WISH and RAIKO from the ISS

Built by members of the Meisei Amateur Radio Club WE-WISH carried an infrared camera for environmental studies. The 320 by 256 pixels images  of the Earth’s surface were transmitted in approx 110 secs using SSTV. The callsign was JQ1ZIJ and the 100mW downlink on 437.515 MHz operated on CW (A1A), AX.25 1200 bps packet radio (F2D) or SSTV (F3F).

Masahiro Arai JN1GKZ has produced a chart that shows the declining altitude of the five CubeSats since their deployment. RAIKO was the largest of the CubeSats at about 2 kg and 10 × 10 × 20 cm and the others being about 1 kg and 10 × 10 × 10 cm. The chart compares their orbital decay with that of ARISSat-1/Kedr (30 kg, 55 × 55 × 40 cm) which was deployed on August 3, 2011 and and re-entered Earth’s atmosphere on January 4, 2012, having spent 154 days in orbit.
