NASA Latest Announced It's Building an Electric Propulsion System to Take Us Into Deep-Space
We have visited Moon and some countries are planning to launch
a colony on the moon now but if we we're going to start travelling to the rest
of the Cosmos, we will need better spacecraft. Keeping that in mind, NASA has
just presented a US$67 million pact to create a latest electric propulsion
system that could ultimately take us a great deal deeper into space. This
electric propulsion system work on a simple principle, in its place of a
chemical propellant electricity is used to get a spacecraft moving.
The technology is
planned to be experienced on a large scale in an upcoming Asteroid Redirect
missions, which basically aims to look for for the ways we could deflect an
asteroid directed to Earth, along with a crewed trip to Mars, scheduled for
around 2030. You all know about Tesla motors and how they work on electricity
and now our spaceships are leaving the same way. To make this work, solar
panels will be used to produce an electric charge (obviously, cloud shield
isn't a difficulty in space), and the involved propellant will be ionized by
means of the collected electricity.
These positively charged ions, shaped by conning electrons
in a magnetic field, are then accelerated out of the vessel to create thrust.
Electric propulsion isn't precisely a new skill. According
to NASA, it's been working on this technology for over 50 years now, but as
with any knowledge, it requires to be build cost-effective, completely safe,
and firm before it can be used practically in a mission. By giving the new
three-year deal to Aerojet Rocketdyne, NASA is confident to speed up the
process.
NASA said "Work performed under the contract could
potentially increase spaceflight transportation fuel efficiency by 10 times
over current chemical propulsion technology and more than double thrust
capability compared to present electric propulsion systems,"
In order to go further in space, the use of less fuel is
crucial. Aerojet Rocketdyne will work on a reference design made by NASA to
yield a thruster, control processing unit (PPU), low-pressure xenon flow
controller, and electrical harness. Xenon is frequently used as a propellant in
ion propulsion structures because of the relative ease with which it can be
ionised.
Currently, NASA's Dawn Mission spacecraft also work with
solar-electric propulsion, but as The International Business Times information,
the thrusters being built by Aerojet are projected to be nearly five times extra
powerful.
