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.

European Space Agency launches radar satellite

Published on Apr 3, 2014
The biggest civil Earth-observation programme ever conceived has begun with the launch of a radar satellite from French Guiana.

The EU's Sentinel-1a spacecraft will be followed into orbit by a fleet of other satellites in the coming years.

Together, they will return an unprecedented volume of data on the state of the planet.

Why we need radar satellites ?

Published on Apr 2, 2014

The launch of the first Sentinel-1 satellite marks a new paradigm in Earth observation focusing on operational missions to support users for decades to come. This first satellite for Europe's environmental monitoring Copernicus programme carries an advanced radar to image Earth's surface no matter what the weather or if it is day or night. Olaf Trieschmann from the European Maritime Safety Agency talks about the need for radar satellites and how data from Sentinel-1 will be used to monitor oil spills and for maritime surveillance. ESA's Josef Aschbacher talks about how the wide range of services offered through Copernicus will make a step change in the way we manage the environment.

Radio amateurs receive NASA ISEE-3 / ICE Spacecraft

Radio amateurs have received signals over a distance of 43 million km from the NASA ISEE-3 / ICE deep space probe which was retired from service in 1997.

On March 1st and 2nd, 2014 radio amateurs were able to detect the beacon signal from the retired NASA deep space probe ICE (International Cometary Explorer) at the Bochum Observatory (Germany). After some changes to the ground equipment and aligning the receive antenna to the predicted position in the sky, the 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).
For this detection the 20m radio telescope from the Bochum Observatory was used. In 2003, AMSAT-DL converted this former industrial monument into a fully functional groundstation for deep space probes. Since 2009 the facility is being used by volunteers almost full time as ground receive station for data from the STEREO mission with its two spaceprobes monitoring the sun from different viewing angles.
The International Sun-Earth Explorer 3 (ISEE-3) was launched in 1978 and became the first spacecraft to orbit the Earth-Sun L1 Lagrange point, measuring the interaction between the Earth’s magnetic field and the Sun. It was the first spacecraft to detect the stream of particles (“solar wind”) approaching Earth. In 1982, the spacecraft was renamed the “International Cometary Explorer” (ICE) and diverted to the Moon, where its gravitational pull placed ICE on a heliocentric orbit. In 1985, the comet Giacobini-Zinner was visited (the first time a comet had been encountered by a spacecraft), followed by observation of Halley’s Comet in 1986.

While the instrumentation on board was still functional and fuel for more trajectory maneuvers was available, support for the ICE mission was terminated in 1997, though the spacecraft transmitter was left on. It was last detected by the NASA Deep Space Network in 2008. Its orbit however results in the spacecraft returning to Earth-Moon space in August of 2014. A small propulsive maneuver and lunar flyby could allow ICE to be directed into an Earth-Sun L1 halo orbit and perhaps resume a science mission, depending on instrument health. However in February 2014 a NASA study determined that the required resources to contact the spacecraft were not available anymore and due to budgetary constraints no further contact attempts were planned. In light of the recent observations and the available facilities in Bochum, additional studies about the economic feasibility to add a suitable uplink are being done.
We would like to thank Jeremy Bauman from KinetX Aerospace (Tempe AZ, USA) for providing the ICE trajectory solution which was essential in finding the spacecraft and Jon D. Giorgini from the Jet Propulsion Laboratory (Pasadena CA, USA) for his support.

The Extraordinary History of Amateur Radio Satellites !!

The Extraordinary History of Amateur Radio Satellites .
Here's a startling fact — more than 73 Amateur Radio satellites have been launched over four decades. The number is astonishing because these sophisticated and ground breaking spacecraft are little known outside the ham radio fraternity.
In fact, private groups of Amateur Radio operators around the globe have built and sent dozens and dozens of Amateur Radio communications and science satellites to orbit since the first, OSCAR-1, was launched on December 12, 1961.

The “ARTSAT: Art and Satellite Project” utilizes a satellite orbiting the earth as a “medium that connects everyday life to the universe”. In the course of the project, a variety of interactive works of media art and other artworks will be created.

The project is carried out in a collaborative effort around a core team of over 70 members from Tama Art University and The University of Tokyo. The latter’s team developed a specialized “art satellite” for artistic purposes, while the team from Tama Art University is in charge of producing works based on data from the satellite, operating a ground station, and distributing data.

“ARTSAT1: INVADER(*)”, the world’s first art satellite, has been selected for a piggyback payload on the Japan Aerospace Exploration Agency’s (JAXA) H-IIA rocket. The ultrasmall 1U CubeSat, measuring only 10 x 10cm and weighing 1.5kg, is scheduled to be launched in February 2014, after which it will be traveling on a circular, polar sun-asynchronous orbit at an altitude of 407km, and with an inclination of 65 degrees.
