To reach high power applications, classic electric thrusters need to resort to clustering many smaller thrusters together, which increases size, complexity and mass. The I sp or Specific Impulse of a rocket engine is merely how fast the exhaust exits said engine.

The faster the exhaust, the more fuel-efficient the rocket is and the higher the I sp. Many people are unaware of just how much we depend on space and satellites in our every-day lives.

Each time you do a search for the nearest cafe or gas station, or perform a wire transfer, or use an ATM, these actions are being triangulated from space. Not to mention all the technology we use in our everyday life that is actually a product of space exploration. Technology is advancing at an astounding rate, however our means to move around and stay in space have not advanced much since the s.

Those satellites mentioned earlier need to be maintained. Otherwise, they become space junk. Junk orbiting around the earth at 17,miles per hour. Satellites are not the only thing that has become junk, upper stages of chemical rockets remain in orbit for hundreds of years. We have launched so many things in space and yet, have never been able to figure out how to efficiently pick up after ourselves.

Being hit by space junk is one of the largest threats to crew members and a spacecraft in orbit. If one of those pieces of space junk were to collide with a major satellite, it could be financially catastrophic and in some cases, threaten the well-being of entire communities.

Our current space economy is dominated by chemical propulsion, with a small niche market for low-power electric engines also known as ion engines. Chemical propulsion is the only way we can get off the earth into space, but once in space, this type of propulsion loses a lot of its efficiency.

Chemical propulsion will still be absolutely necessary to support a growing space economy, however if we want to create a sustainable and efficient presence in space we need to develop and implement high-power electric propulsion.

As nuclear electric technology matures we will be able to scale-up to meet it with multi-megawatt engines, this will be crucial to opening up human deep-space exploration.

As a species, it is important for our survival to learn how to live in new environments. The design is also more reliable than chemical rockets and parts should last longer before requiring replacement. Ad Astra founder and former astronaut Dr. Specific plans for the tests have not been revealed at this time. While VASIMR would be an invaluable tool for making trips to Mars viable in the near future, initial plans are to use the rocket to haul cargo from low Earth orbit to low lunar orbit.

VASIMR could double the current payload maximum of chemical rockets pounds versus pounds when configured for a six month journey between the Earth and Moon. TFOT has reported on other innovative rocket engine technologies and spacecraft including an antimatter engine using positrons for fuel, a new privately developed lunar lander , an experimental supersonic combustion ramjet , or scramjet, and tests of a methane-powered rocket engine.

Janice Karin has a B. Theoretically, large solar panels could be used as well, but the weight of such panels would pose an issue at launch.

Part of this controversy appears to be due to miscommunication. Another bit of controversy concerns the first part of the trip. Any spacecraft intended to work with the engine would either need to be built in space or would have to reach space via a chemical rocket.

For now, Ad Astra will continue to develop its technology in the hopes of helping humanity cut way down on its travel time to Mars and beyond. Care about supporting clean energy adoption? Find out how much money and planet!
