One Rockin’ Rocket Engine April 6, 2012

Every day I visit a couple of great websites dedicated to space. I hope that I will be greeted by the banner announcement that someone has invented a workable “warp drive”. I know, “hopeless dreamer” you think. Maybe, but if I can’t have warp drive I will settle for a tiny step in the right direction.

The most elegant solution to moving space travelers around our own planetary system at reasonable speeds is under development at Ad Astra Rocket Company in Webster, Texas. http://www.adastrarocket.com/aarc/

These people understand that it is no fun floating for months in a spam can for months trying to catch up with Mars. They are working on a concept they call the Variable Specific Impulse Magnetoplasma Rocket or VASIMR®. Now I don’t know about you but that is a very cool sounding acronym. Not only is the name cool but it promises to reduce the six month float in space to get to Mars to around four months!

It works on the principal of superheated plasma: Xenon, or other gas to produce thrust an very low fuel flows. They do this by using a magnetic containment system since no material is capable of the sustained temperatures of the plasma. The concept is solid & the science is based on decades of research by Dr. Franklin Chang-Diaz, research scientist & former NASA astronaut.

Thy have the attention of Dr. Chang-Diaz’s former employer, NASA. Their VF-200-1 engine will be flown on the International Space Station (ISS) to validate the concept. This may not be warp drive but reducing the trip time to Mars by a third is significant. Look for an article on this new piece of revolutionary rocket technology soon.
