Tomsk-TPU-120 CubeSat Video

The Russian space agency Roscosmos has released a video of the Tomsk-TPU-120 CubeSat commemorative transmission from the International Space Station.
The satellite was developed by students at the Tomsk Polytechnic University to test new space materials technology and is the world’s first space vehicle with a 3D-printed structure. It was launched from Baikonur to the ISS on March 31, 2016 in a Progress-MS-2 cargo vessel. It will be deployed by hand during a future Russian spacewalk (EVA), which is why unlike other CubeSats this one has a handle. The call sign of the satellite is RS4S.

Tomsk-TPU-120 CubeSat Callsign RS4S

In May 2016 the Tomsk Polytechnic University celebrated its 120th anniversary. As part of the celebrations on May 10/11 the Tomsk-TPU-120 was activated in the ISS and transmitted a greeting to Earth inhabitants, recorded by students of the university in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese.
The greeting message was transmitted once a minute on 437.025 MHz FM. One of the Kenwood transceivers on the ISS provided a cross-band relay, re-transmitting the signal on 145.800 MHz FM.
The video, recorded in the Russian ISS Service Module, shows the CubeSat and the amateur radio station.

ISRO Tests Reusable Space Shuttle

Published on May 22, 2016 by India Today  @ youtube India Today
In a significant step towards developing a full fledged reusable launch vehicle, Indian Space Research Organisation tested a sleek winged prototype through a short test flight. The first such flight which is a technology demonstrator has been launched from the Satish Dhawan Space Centre in Sriharikotta. The idea to develop a vehicle with delta wings and an angled tail fin is to fly into space and land on earth like an aircraft. This will help cut cost satellite launches by 10 times and an advanced version of the vehicle could also be used for manned missions as well.

Low cost APRS !!

I had no transmitter module, to test my new Arduino sketch except the low
cost JMR-TX1 module. For my surprise it works like a charm and succeeded
to transmit packet frames without missing any,  just like a robust FM transmitter
module !!! .
On spectrum analyzer I noticed a lot of noise, but a simple output filter can
boost using of this cheap  low power module for more lab and field experiments.

The International Sun-Earth Explorer (ISEE-3)

The International Sun-Earth Explorer (ISEE-3) is a NASA spacecraft that was launched in 1978 to study Earth’s magnetosphere. It was repurposed and renamed the International Cometary Explorer (ICE) in 1983 to study two comets and has been in a heliocentric orbit since then, traveling just slightly faster than Earth. It’s finally catching up with Earth from behind with the closest approach expected in August, 2014.

Since NASA no longer has the capability to receive and command the spacecraft a group of amateurs, with NASA’s permission, decided to do it for themselves.

On March 1-2, 2014 radio amateurs at the Bochum Amateur Radio Facility in Germany were able to detect the beacon signal from the spacecraft over a distance of 43 million km. After some changes to the ground equipment and aligning the receive antenna to the predicted position in the sky, the 2 GHz beacon signal could positively be identified due to its frequency, the position in the sky and the frequency shift due to the radial velocity (Doppler shift).

In June Dennis Wingo KD4ETA and other volunteers succeeded in commanding the spacecraft using the Arecibo dish in Puerto Rico.

Space Buffs Make Contact With Discarded NASA Probe


A group of citizen scientists has commandeered a NASA spacecraft that was launched in 1978 and had gone unused since 1997.
Today the group made first contact with the International Sun-Earth Explorer-3 (ISEE-3) when the spacecraft acknowledged receiving a signal from the Arecibo radio telescope in Puerto Rico, says Keith Cowing, co-director of the ISEE-3 Reboot Project, a group of about 20 volunteer space buffs. “We knew we could do this—it’s a vindication,” he says. “It’s sort of like reaching back in time to grab something that otherwise would have been lost.”

Cowing says that the group is now getting telemetry data from the spacecraft. Over the coming days, they will try to understand the health of the spacecraft and its 13 scientific instruments. The spacecraft was launched to study space weather and is due to make a close pass around the moon.
Next month, they plan to instigate a burn with the remaining fuel and move the spacecraft into a new orbit. Also in June, they plan to start communicating with ISEE-3 from a second radio telescope, a 21-meter dish at Morehead State University in Kentucky. This dish is more movable than the massive Arecibo telescope and can better track the spacecraft as it gets closer to Earth, Cowing says.
The ISEE-3 Reboot Project raised more than $150,000 in crowd-funding to support its volunteer efforts.

Amateur Radio-Developed Software Assisting in Search for Missing Flight MH370


US Navy personnel helping to look for missing Malaysia Air Flight MH370 are using the signal-processing and analysis package Spectrum Laboratory by Wolf Buescher, DL4YHF, to analyze recently detected 37.5 kHz “pings” that may be from the missing plane’s “black box.” Some Spectrum Laboratory screen shots as seen aboard the Australian Defense Vessel Ocean Shield were shown on TV. The US Navy personnel are guests aboard the Australian ship. VLF experimenter Warren Ziegler, K2ORS, said the software is the same package Amateur Radio experimenters used recently to detect transatlantic signals on 29 kHz.

“Wolf’s package is very first-rate software, and I know that there have been other professional uses, but this was quite an interesting one!” Ziegler said.

The software began as a simple DOS-based FFT program, but it is now a specialized audio analyzer, filter, frequency converter, hum filter, data logger and more, and it is available for download from DL4YHF’s Amateur Radio Software site.

Buescher said he was skeptical about the initial “ping” detection by one of the search vessels, but now, he says, “the spectrogram taken by the US team aboard Ocean Shield is convincing.” He said a screenshot from Australian TV clearly shows the “bip-bip-bip” ultrasonic bursts or pings, “just as they should look,” rather than a “just a wobbly carrier that comes and goes.”

“In slow-CW terms, it would be an ‘outstanding signal.’” Buescher said. “Now keeping fingers crossed that the [“black box”] batteries last a bit longer than specified. The experts say the pinger’s battery usually degrades slowly, instead of going QRT abruptly.”

Sentinel-1 soundtrack

Published on Apr 3, 2014
Sentinel-1A, the first satellite for Europe's environmental monitoring Copernicus programme, is being launched from Europe's Spaceport in Kourou, French Guiana on 3 April 2014. It will be lofted into orbit on a Soyuz rocket.

This animation shows some of the critical stages delivering Sentinel-1 into orbit around Earth. After separating from the Fregat upper stage, the satellite takes around 10 hours to deploy its 12 m-long radar and two 10 m-long solar wings. This deployment sequence is unique, choreographed to ensure that both deploy in the safest possible way. This approach also allows power from the wings to be available as soon as possible so that the satellite is independent.

Delivering vital information for numerous operational services, from monitoring ice in the polar oceans to tracking land subsidence, Sentinel-1 will play a key role in the largest civil Earth-observation programme ever conceived.

The animation is set to a track called Sentinel by Mike Oldfield, a world-renowned musician and big space fan.
