Looking for an escape from planet Earth? We look at the quickest and most likely 5 ways to get to Mars and start your new adventure.
1. Ask a genius
Serial entrepreneur extraordinaire Elon Musk announced earlier this year that Space X has a Mars mission in its sights. In an hour long video, the billionaire founder announced his aim to begin missions to Mars by 2018, and manned flights by 2024. The planned massive vehicles would be capable of carrying 100 passengers and cargo with a ambitious cost of US$200,000 per passenger. He’s joined by other ambitious privately funded projects including Amazon founder Jeff Bezo’s Blue Origin, which describes a reusable rocket booster and separable capsule that parachutes to landing. Meanwhile American inventor and chemical engineer, Guido Fetta has pionered a concept long discussed by the scientific community, electromagnetic propulsion, or EM drive, which creates thrust by bouncing microwave photons back and forth inside a cone-shaped closed metal cavity. Rumours this week from José Rodal from MIT that NASA was ready to release a paper on the process, which would be game-changing for space travel as the concept doesn’t rely on a propellant fuel.
2. Hitch a ride
In November 2016, NASA and CSIRO’s Parkes telescope opened the second of two 34-m dishes that will send and receive data from planned Mars missions, while also listening out for possible alien communications as part of UC-Berkeley-led project called Breakthrough Listen, the largest global project to seek out evidence of alien life. The Southern Hemisphere dish joins others in the US in using signal-processing hardware to sift through radio noise from Proxima b, the closest planet to us outside of the solar system. Whether an alien race would be willing or able to offer humanity a ride off its home planet is another question.
3. Aim high
While they are focused on getting out of the solar system, a team led by Dr. Philip Lubin, Physics Professor at the University of California, Santa Barbara think they could get the travel time to Mars down to just three days (as opposed to six to eight months). Their project, Directed Energy for Relativistic Interstellar Missions, or DEEP-IN, aims initially send “wafer sats”, wafer-scale systems weighing no more than a gram and embedded with optical communications, optical systems and sensors. It’s received funding of US$600,000 to date from NASA Innovative Advanced Concepts, and theoretically could send wafer sats at one-quarter the speed of light – 160 million km an hour – using photonic propulsion. This relies on a laser beam to ‘push’ a incredibly small, thin-sail-like object through space. While it may seem a long shot for passenger travel, the system also has other applications in defence of the Earth from asteroids, comets and other near-earth objects, as well as the exploration of the nearby universe.
The Mars One project already has 100 hopeful astronauts selected for its planned one-way trip – out of 202,586 applicants. The project is still at ‘Phase A’ – early concept stage – in terms of actually getting there, but makes the list of the top 5 ways to get to Mars due to the large amount of interest: it has raised US$ 1 million towards developing a practical way to safely land some of these select few on the red Planet.
5. Ask the experts
In 2020, Australia will host the COSPAR scientific assembly, a gathering of 3000 of the world’s top space scientists. The massive conference will no doubt include some of the top minds focussed on this very problem, offering new hope in our long-term quest for planetary travel.
“We come to the table with a bold vision for our nation’s place in science – and through science, our place in space, said Australia’s Chief Scientist, Alan Finkel.
