A SONG THAT I LISTEN TO WHEN I THINK OF THE MISSION I CALL THE EXODUS-AE... First in many things, it's the final word in colonizing space and the miracle of other worlds. Generations of human-kind will one day inherit the heavens and the Earth.

The hope for peace and real freedom. The dream of one day being independent of all this world is and soon WAS.... Life AE- After Earth.
 Smiley I see this vision, vividly.

Here's one for you, Herefornow:

Plasma Rocket Could Travel to Mars in 39 Days
October 6, 2009 by Lisa Zyga Ad Astra VASIMR

(PhysOrg.com) -- Last Wednesday, the Ad Astra Rocket Company tested what is currently the most powerful plasma rocket in the world. As the Webster, Texas, company announced, the VASIMR VX-200 engine ran at 201 kilowatts in a vacuum chamber, passing the 200-kilowatt mark for the first time. The test also marks the first time that a small-scale prototype of the company's VASIMR (Variable Specific Impulse Magnetoplasma Rocket) rocket engine has been demonstrated at full power.

"It's the most powerful plasma rocket in the world right now," says Franklin Chang-Diaz, former NASA astronaut and CEO of Ad Astra. The company has signed an agreement with NASA to test a 200-kilowatt VASIMR engine on the International Space Station (ISS) in 2013. The engine could provide periodic boosts to the ISS, which gradually drops in altitude due to atmospheric drag. ISS boosts are currently provided by spacecraft with conventional thrusters, which consume about 7.5 tonnes of propellant per year. By cutting this amount down to 0.3 tonnes, Chang-Diaz estimates that VASIMR could save NASA millions of dollars per year.

But Ad Astra has bigger plans for VASIMR, such as high-speed missions to Mars. A 10- to 20-megawatt VASIMR engine could propel human missions to Mars in just 39 days, whereas conventional rockets would take six months or more. The shorter the trip, the less time astronauts would be exposed to space radiation, which is a significant hurdle for Mars missions. VASIMR could also be adapted to handle the high payloads of robotic missions, though at slower speeds than lighter human missions.

Chang-Diaz has been working on the development of the VASIMR concept since 1979, before founding Ad Astra in 2005 to further develop the project. The technology uses radio waves to heat gases such as hydrogen, argon, and neon, creating hot plasma. Magnetic fields force the charged plasma out the back of the engine, producing thrust in the opposite direction. Due to the high velocity that this method achieves, less fuel is required than in conventional engines. In addition, VASIMR has no physical electrodes in contact with the plasma, prolonging the engine's lifetime and enabling a higher power density than in other designs.

I like the idea of a plasma engine... Thank you for this idea, because I would consider this for the landers and exploration vehicals.
As for the Exodus Station, I am looking toward palsed laser propulsion.

Very impressive.  Of course, all this would be for naught unless a way to terraform Mars can be found, and a way to do it quickly.

But if we can use these technologies to prolong life....
A 40 year mission would be more practical. Mars is not large enough to sustain a thicker atmosphere. Adapting to a world like-





Would be more likely for a mission like this....

Chemistry lesson...



Discovering what energies can manipulate molecules is key in a self-assembly process... So what types of compounds can be produced, and by changing the properties of atoms, what new materials can be made?
