TubeSat aims to test Ion Engine

Wes Faler is building a small satellite called Fluid & Reason Engine Test Satellite 1 or FRETS1.

FRETS1 is a TubeSat-style picosatellite that aims to fly in 2013 on an Interorbital Systems Neptune rocket into a 310 km sun synchronous orbit. Its mission is to test a new kind of ion engine, one designed for higher thrust and lower power than traditional designs.

It’s planned to use a closed cell foam filled with pressurized nitrogen, vaporizing the supporting plastic and releasing the enclosed nitrogen using a spark system similar to that used by Pulsed Plasma Thrusters (PPTs).  PPTs create an arc across the face of a solid Teflon bar, turning a few micrograms of Teflon into plasma.  The plasma moves along the PPT’s cathode and anode by Lorentz forces, much the same way that a rail gun accelerates its conducting projectile.

This video gives a brief overview of what a TubeSat is.

Note it is understood the first launches will take place in California rather than the site mentioned in the video.

To the Moon on a Shoestring



Tor Fos Mortensen gave a presentation about Euroluna to the European Lunar Symposium in Berlin , April 19-20, 2012.

Euroluna are a Danish amateur team participating in the $30 million Google Lunar X PRIZE contest to be the first privately funded team to land and drive a rover on the Moon.

Their first Amateur Radio CubeSat Romit-1, fitted with an Ion motor, is planned to launch on an Interorbital Systems Neptune 30 rocket.
