  First picture from ESTCube-1 ham radio CubeSat

The first picture taken
by the amateur radio CubeSat *ESTCube-1* in space has been released.

ESTCube-1 was launched from Kourou in the Caribbean on May 7 at 0206 UT on
an ESA Vega rocket into a 704 km orbit.


The hard work of the first two weeks has paid off and the CAM team, leaded
by the University of Tartu Computer Technology graduate student Henri
Kuuste has this to say: The camera works perfectly and so do all the other
subsystems, needed for taking the photo. The first image was captured on
May 15 over the Mediterranean Sea, showing the sea, Sahara desert, and
Tunisia.

On Monday, May 13 the whole ESTCube-1 team was invited to the reception of
the rector of University of Tartu to celebrate the success of the
satellite. Watch the video (in English) at http://www.uttv.ee/naita?id=17163

ESTCube-1 was built by students at the University of Tartu. The main
mission of the satellite is to test electric solar wind sail technology, a
novel space propulsion technology that could revolutionize transportation
within the solar system. It will deploy a 10 meter conductive
electrodynamic tether and the force interacting with the tether will be
measured.

The technology is based on the electrostatic interaction between the
electric field generated by the satellite and the high-speed particles
being ejected from the Sun. A spacecraft utilizing this method would first
deploy a set of electrically charged wires, which allow to generate an
electric field over a large area. This area effectively forms a “sail� that
can be pushed by the charged particles by being diverted by it and
therefore transferring momentum to the craft.

ESTCube-1 uses these frequencies:
437.252 MHz – CW beacon, callsign ES5E/S
437.505 MHz – 9600 bps AX.25 telemetry, callsign ES5E-11
