What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Xenon ion and water cubesat engines for interplanetary cubesats with costs ten thousand times less

RATE THIS! +3
Posted in Science on 1st Jan, 2014 10:42 PM by AlexMuller

Benjamin Longmier, Michigan University, is developing the CubeSat Ambipolar Thruster (CAT), a new rocket propulsion system powered by the Sun and propelled by water, which will push small spacecraft like CubeSats around and far beyond the Earth. 

 
They received a $200,000 private donation and have raised over $96,000 on Kickstarter.
 
What can be enabled with successful cubesat ion drive
 
* interplanetary missions to Mars and Europa for about $1 million
* Ten interplanetary cubsats for a solar system wide internet
* Cheaper satellite wi-fi around the earth
* Future combination with Spacex reusable rockets, Planetary resources cheap space telescopes, Googlex low cost space robotics for radical lowcost space exploration
 
A private donor will pay for the Xenon ion technology and a launch in 2014 aboard a NASA rocket. They hope their propelled CubeSats will one day fly to Saturn's moon Enceladus and Jupiter's moon Europa, both of which hold water – and perhaps life. A fleet of CubeSats with propulsion in orbit around a planet or moon can do a lot of things that big expensive satellites cannot, such as monitoring several locations in the atmosphere at once.
 
Propelled CubeSats could even be useful back here on Earth. Creating a universal "satellite Wi-Fi", like existing satellite phone coverage, would require thousands of big satellites, which is prohibitively expensive. But you could dump a thousand CubeSats in one place then spread them out to the right points, for a fraction of the price.
 
CAT produces thrust from the expansion of a super-heated 350,000 °C plasma stream. Plasma is an ionized gas that can be accelerated to produce thrust (F=ma). The force generated by this thruster will be very low (micro-newtons) but very efficient. The engine will be turned on for long durations, accelerating the spacecraft to much higher velocities than a typical chemical rocket. Our first test will use xenon, a safe, non-toxic gas typically used in large-scale plasma thrusters. With support from you, we can begin work on our long-term goal of designing a water-based propellant system to make the first truly sustainable plasma propulsion device for CubeSats.

This could be a source of power for space exploration that NASA has been looking for. If successful it will help reach and possibly land on NASA target sooner Reply

They are doing great with the funds and public seems to be supportive. $200,000 in private donation and over $96,000 on Kickstarter is a great start Reply
