SCIENTISTS HAVE INVENTED A NEW PROPULSION SYSTEM THAT COULD TRANSPORT HUMANS TO MARS IN 45 DAYS
For
NASA and many space researchers across the world, Mars has been a long-shot
aim, but they believe the Red Planet could one day be a prospective human
colony. According to NASA's estimations, the theoretical journey time for
people to reach Mars is roughly 9 months, with a minimum distance between Earth
and Mars of 54.6 million kilometres. Engineers in Canada, on the other hand,
have developed a revolutionary laser-propulsion system that claims to cut
journey time in half to just 45 days.
According
to a study, humans can travel to Mars in 45 days.
McGill
University academics and engineers claim to have developed a revolutionary
laser-propulsion-based spacecraft that may transport passengers from Earth to
Mars in just over six weeks. The researchers propose a directed-energy
propulsion system based on Earth that would jet-shot a spacecraft from Earth to
Mars in the allotted time.
The
researchers claim that by using the method, they will be able to accelerate a
spaceship very swiftly near Earth. The spacecraft is propelled deeper into
space by laser beams that travel at a fraction of the speed of light. The
spacecraft will reach Mars in the next month as a result of the acceleration.
"Using
quick transit to Mars as a design goal, the applicability of directed energy to
spacecraft mission design is investigated. "Continued advances in photonic
laser technology are expected to enable an Earth-based laser array of
unparalleled size (10 m diameter) and power (100 MW)," according to a
study article published by McGill University researchers.
The
primary spacecraft will arrive on Mars in 45 days, while the rest of the
spacecraft will return to Earth to be recycled for the next flight.
"A
phased-array laser of this scale and with atmospheric compensation might
transmit laser power to spacecraft in cislunar orbit, where the incident laser
would be focussed into a hydrogen heating chamber through an inflatable
reflector." The hydrogen propellant is subsequently expelled through a
nozzle, resulting in 3000s specific impulses. "Through a burn-back manoeuvre
to return the propulsion unit while still within range of the Earth-based
laser, the architecture is proved to be instantaneously reusable," it
continues.
For
those who don't know, nuclear fission-powered rockets can achieve this
shortened trip time, but they come with radiation dangers. This problem looks
to be solved by this new system.
Although
this appears to be a viable strategy for reaching Mars or exploring other
deep-space regions of our cosmos, there is currently no spacecraft to test this
notion.
While
Elon Musk believes that humans will be able to visit Mars within the next six
years, NASA and China plan to transport humans to Mars by the 2030s. As a
result, we may expect researchers and engineers to concentrate on developing
and building a spaceship to support the laser-based directed-energy propulsion
system.
