VASIMRÂ® VX-200 Meets Full Power Efficiency Milestone
Ad Astra Press Release
Houston, TX â€“- Nov. 23, 2010 — Ad Astra Rocket Companyâ€™s VASIMRÂ® VX-200 rocket prototype demonstrated its highest power efficiency and performance so far in tests, which ended Friday November 19 at the companyâ€™s Houston laboratory. Last weekâ€™s results met the efficiency milestone set by the company as it specifies the requirements for the VF-200 flight engine for the International Space Station. The VX-200 is the full power laboratory prototype that provides the technical basis for the design of the flight hardware.
The Ad Astra Rocket Company, founded in 2005 by Costa Rican astronaut and physicist Franklin Chang, announced Wednesday that it will become a limited public corporation, offering stock to investors willing to pay a minimum of $25,000 on Costa Ricaâ€™s National Stock Exchange.
Building a foundation for commercial crew As the debate over commercial crew development continues in Washington, NASA and industry are taking initial steps on such efforts. Jeff Foust discusses some of the ongoing efforts and planning that continue despite political uncertainty.

VASIMR: hope or hype for Mars exploration? An advanced electric propulsion concept known as VASIMR has won support from some, including NASA leadership, for its potential to greatly reduce the travel times for human Mars missions. Jeff Foust reports that some Mars advocates are skeptical, at best, of the ability of this system to match expectations.
Former Astronaut Chang Said Costa Rican Should Insert Itself In Aerospace Development Inside Costa Rica
Costa Rica’s own former NASA astronaut, Franklin Chang-Diaz, feels that Costa Rican businesses should take advantage of the aerospace technology that is ripe for local businesses to be involved in a field with enormous possibilities.

A mission trajectory study estimated that a VASIMR-powered spacecraft could reach the red planet within 40 days if it had a 200 megawatt power source. That’s 1,000 times more power than what the current VASIMR prototype will use, although Ad Astra says that VASIMR can scale up to higher power sources.
NASA will study the use of Ad Astra Rocket Company’s VASIMR engine for use on a lunar tug concept that would travel between low Earth orbit, lunar orbit and libration points, according to a January 21 procurement document. A video from Ad Astra showing how such a mission would work is above.
Ad Astra Rocket Company, a world leader in plasma rockets and MEI Technologies, Inc., a nationwide aerospace, defense and technology company, have joined forces creating a strategic alliance in support of Ad Astra’s Variable Specific Impulse Magnetoplasma Rocket (VASIMRÂ®) rocket development.

Before launching speedier Mars missions, Chang Diaz proposes some practical uses of the rocket closer to Earth. It could, for example, act like a DHL in outer space, in which plasma-thrust crafts would transport packages, mainly fuel, to satellites or spaceships on the cheap â€” well, cheaper. Shipments that today run to the tune of a billion dollars, according to the CEO, would cost half a billion on Ad Astra spacecrafts.
He mentioned another use that flies closer to the heart of his eco-friendly homeland. These ships could start to clean up the clutter left by disused satellites.
Ad Astra Rocket Companyâ€™s VASIMRÂ® VX-200 rocket prototype reached its highly- coveted 200 kW maximum power milestone at 11:59 am (CST) in tests conducted at the companyâ€™s Houston laboratory. The DC power trace actually exceeded the design requirement by 1 kW and exhibited the clear signature of a well established plateau at peak power (see graph).

Route to Mars may come through Costa Rica Tico Times
The route to Mars may go through Costa Rica. On Wednesday, Ronald Chang, executive director of Ad Astra Rocket Company Costa Rica, gave a presentation at the National Museum that detailed how Costa Rica has the opportunity to serve as a vital cog in the first-ever mission to Mars.
In his presentation, Ronald Chang explained that his brother created an ion plasma rocket, the Variable Specific Impulse Magnetoplasma Rocket, known as VASIMR, which can reach Mars in 39 days. Using technology currently available, a rocket can travel to Mars in eight to nine months.

Several space missions have already used ion engines, including NASA’s Dawn spacecraft, which is en route to the asteroids Vesta and CeresMovie Camera, and Japan’s spacecraft Hayabusa, which rendezvoused with the asteroid Itokawa in 2005.
But a new engine, called VASIMR (Variable Specific Impulse Magnetoplasma Rocket), will have much more “oomph” than previous ones. That’s because it uses a radio frequency generator, similar to transmitters used to broadcast radio shows, to heat the charged particles, or plasma.
Ad Astra Rocket Company has successfully demonstrated operation of its VX-200 plasma engine first stage at full power and under superconducting conditions in tests conducted today at the companyâ€™s Houston laboratory. This achievement is a key milestone in the engineâ€™s development and the first time a superconducting plasma rocket has been operated at that power level.
