The advancement of technology never ceases to amaze us, since Mars could be reached in three days with laser propulsion, a new system currently being developed by NASA. A normal trip to Mars is set to take anywhere between six months and two years, depending on the position of the red planet and our own in orbit with the Sun.
This being said, completing the journey to Mars in only three days is something truly revolutionary. The Laser Propulsion System will make travelling through space much faster, but there is still a lot of work to be done until it will be complete. At the moment, scientists are trying to put their theories into practice similar to the way they did with accelerators and the particles used for the functioning of those.
Even though making particles travel at light speed is doable, there is a whole different matter of things when we talk about large objects like spacecraft. Up until now, bigger objects could only achieve fewer than three percent of light speed because of their physical limitations. Unfortunately, we have yet to bypass nature’s laws.
In spite of this seemingly impossibility, a new method might just do the trick: lasers could carry spacecraft within our solar system. In order to do so, we would have to build giant lasers on Earth that would propel spacecraft. However, this theory seems to work on large scale objects as well, as opposed to the particle generator.
But how would this actually work? Light particles feature momentum and energy and thus when they reflect off the surface of an object they provide a push. By creating a large amount of light particles, together they would be able to push space shuttles into space.
Laser Propulsion has been previously used and presents little limitations in terms of transportation. Scientists have agreed that it is a realistic method that might be put into practice as early as the next decade. Furthermore, it is definitely a better way of sending multiple shuttles into our solar system, be they unmanned or manned expeditions.
The Laser Propulsion technology is also better in terms of resources and finance. The classic fuel-based propulsion is not only extremely expensive, but it can also turn harmful and is always at risk of running out of fuel.
Mars could be reached in three days with laser propulsion, and if the concept is implemented it will surely make astronauts very happy.
