Medgar Evers College students help develope ‘CubeSat’ for NASA communication satellite
Eagerly await ‘CUNYSAT’ lift-off to test 3 year-long science experiment.

For a little piece of equipment, the 4×4-inch cube tucked in an anti-static bag in a plastic lined clean room at Medgar Evers College is pretty huge.

When it heads into space next year the CubeSat, as it is called, will be the culmination of three years of computer programing, engineering and testing involving more than 60 students — most of them from Medgar — from colleges across the Metro area.

Medgar professor and Project Director Shermane Austin said creating the satellite, dubbed CUNYSAT, allows students to “get experience in what NASA does, and also lets the faculty understand the science involved in these things.

“This not like a puzzle that you just put all the pieces together and see if it works,” she said. “There is a significant amount of work by the students.”

Last week several students, including Elston Alexis, Leston AlexisRalph DumervilVinchencia Henderson, Fari Lindo, Kirt St. Louis, and Bridgette Miles joined former students Riguel FabreErnst Etienne and Patrick Dumervil, as well as Austin and physics professor Leon Johnson and computer science professor Laura Zavaka to discuss the project.

Austin said students from Cornell University, City College of New York, Queensborough College, The College of Staten Island, Cooper Union, Brooklyn College and the New Jersey Institute of Technology have contributed to the project.

Basically students were charged with designing mechanical, electrical, communication, date handling, and command systems in the cube which could survive the violent vibrations of a rocket launch and the hostile temperatures of space and still communicate with a ground station manned by students at Medgar.

Although students followed some guidelines already established by National Aeronautics and Space Administration, they were responsible for writing software and repeatedly testing each system.

It is not nearly as simple as it sounds. Patrick Dumervil noted that the electrical system had to be designed to run off a conventional and a solar battery which had to be recharged by solar panels fixed to the cube.

“My job was to make sure the electrical system is balanced,” he said.

“We have to make sure the integrity of the cube is maintained,” said Etienne. “Basically the whole thing is to just maintain the integrity of the Cubesat and make sure it survives.”

The systems are installed in the cub in a clean room — students had to wear gloves, masks and paper clean suits to maintain the sterile environment.

The cube is expected to spend about 120 days in space before falling to earth, Austin said.

The launch date is secret, but Garrett Skrobot, a NASA launch engineer who created the program (formal name Educational Launch of Nanosatellite, or ELaNa) three years ago said he is only awaiting administrative approval to schedule the CUNYSAT for a space flight.

NASA has launched eight cubes so far, and has another 17 awaiting a launch date. Skrobot said he expects that Medgar will design even more sophisticated cubes for future launches. “After all, this is their first one,” he said.

Lindo, part of the ground team writing the communication software, said the team is still hopeful it can include more ambitious experiments in this first cube.

“We’re still trying to see if we can do some ionospheric experiments,” he said.

“Before working on this project I had no idea about these systems,” said Elston Alexis. “Within a few days of coming in I had learned how to track a satellite. This is a great learning experience, and it looks good on a resume.”

Miles said she is so involved in the project that “sometimes late at night I’ll get an idea and sit straight up in the bed. It really is exciting.”

Delfi-C3 (DO-64) – 4 years in orbit

Delfi-C3_DO-64_Team

Delfi-C3 (DO-64) Team at the AMSAT-UK International Space Colloquium 2008 in Guildford

On April 28, 2012 the nanosatellite Delfi-C3 (DO-64) celebrated 4 years in orbit and is still alive and kicking!

This 3-unit CubeSat, developed by the Technical University of Delft in the Netherlands has been largely developed by students and performed technology demonstration experiments for the space industry in the Netherlands. After being launched on PSLV-C9 in 2008 it has been circling the earth for 1461 days (exceeding its design lifetime with 1371 days)!

The satellite still broadcasts its telemetry and measurement data which can be received using simple amateur radio equipment and using the RASCAL software (available on the Delfi website: http://www.delfispace.nl/index.php/participation/radio-amateur-participation).

The satellite project was also the birthplace of ISIS – Innovative Solutions In Space as the company’s founders and a significant number of its employees have worked on the satellite project at the start of their careers. We congratulate the university with the milestone and excellent demonstration that well coordinated student satellite projects can produce great results and exceed all expectations.

Jeroen Rotteveel

Ecuadorian CubeSat will monitor near-earth objects

Ecuadors first satellite NEE-01 Pegasus is slated to launch from Yasny this October on the same DNEPR rocket as the AMSAT-UK FUNcube-1.

NEE-01 Pegasus is a 1U CubeSat with two large (for a CubeSat) deployable solar panels and the Ecuadorian Civilian Space Agency (EXA) indicates 28.8 amps can be generated. There is an onboard camera to send live video from space from a 3 watt TV transmitter in the 902 MHz band along with a beacon that will send an ID and Ecuador’s national anthem.

NEE-01 Pegasus LogoOn April 25, EXA announced that it will be adding a mission to NEE-01 Pegasus: It will help monitoring near-earth objects from orbit using its onboard 720p HD video camera and will also help in the catalog and control of orbital debris (space junk), this new mission will turn the NEE-01 in to the first online, real time orbital video sentry for the planet, as the satellite has the capability to stream its video signal directly to the Internet.

It is hoped NEE-01 Pegasus will be able to detect medium to small sized near-earth objects, like very small asteroids which are normally very difficult to detect but have enough mass to pose a threath to populated areas, like the one which exploded over California in April.

Another of the satellites objectives is to serve as a space platform for elementary education.

The satellite will send two signals that will be received and decoded by the EXA’s HERMES-A ground station in Guayaquil and then uploaded live to the Internet using Twitter and Facebook.

The first signal will contain text book questions and the second will contain an image related to the question. If the students are able to answer the question correctly they will be granted access to the video camera onboard the spacecraft and will be able to see earth from space as the astronauts see it in their space missions.

More advanced students will have access to the pure radio signal so they can try decoding it by themselves. The EXA will provide them with the appropriate support software free of charge.

First-MOVE is an amateur radio CubeSat being built by students at the Technical University of München.

MOVE stands for München Orbital Verification Experiment. The 1U CubeSat carries a CCD camera and has two deployable solar panels carrying a new generation of solar cell – triple junction GaAs / Ge.

The transceiver, supplied by ISIS, uses a UHF uplink and VHF downlink. The antennas are mounted on the ends of the deployable solar panels.

The frequencies for First-MOVE were coordinated by the IARU as:

Downlink: 145.970 MHz
Uplink:     435.520 MHz

This video shows First-MOVE preliminary vacuum test at the LRT facilities. The EQM model was tested in vacuum conditions and at medium/low temperatures (10°C).

Whistle-like signal in Amateur Radio 40m band

OZ9AEC has found a strange signal in the 7 MHz band using his AMSAT-UK FUNcube Dongle with an HF up-converter.

A strange whistle-like signal received on the 40 meter band using Gqrx software defined radio receiver and a Funcube Dongle equipped with a shortwave converter. The signal appears to be amplitude modulated with suppressed lower side band (just like UVB-76 😉 ) Is it an ionosonde or a numbers station?
