Glen Nagle, of CSIRO Astronomy and Space Science, told nine.com.au that Earth is now in "opposition", meaning Mars and the sun will be on precise opposite sides of our planet.
While the Martian atmosphere does contain carbon dioxide, it can not support the formation of liquid water because it is to thin and cold.
Right now, liquid water can't form on the surface of Mars.
This is an artist's model of an early Mars - billions of years ago - which may have had oceans and a thicker atmosphere.
But NASA is sending a robotic lander to study the interior of Mars.

Each habitat must have enough room to comfortably house four people for up to a year, TechCrunch reports, and would be "largely assembled autonomously", meaning machines must complete most of the building process, with minimal human intervention.
Trump's willingness to meet with Iran is diplomatic over-confidence, Dem says
The US president's comments come a few days after he and Iran's leaders exchanged barbs threatening each other with war. . Since then, Tehran's clerical establishment has been under increasing US pressure and the prospect of renewed sanctions .
Planetary scientists at the University of Colorado at boulder (USA) found that the terraforming of Mars in the near future is impossible.
If you miss this approach, the next time you'll catch one will be in 2020, when it will be 62.07 million kilometres from Earth.
The pictures were taken in June and July by the NASA/ESA Hubble Space Telescope, and show that "Earth isn't the only planet where intense spring and summer storms wreak havoc", the USA agency said in a statement.
Another source is Carbon dioxide attached to dust particles in Martian soil, which could be heated to release the gas.
That means Mars, for all intents and purposes, is humanity's next stop.
Although potentially greater reserves of Carbon dioxide could lie deep beneath the Martian surface, these are not easily accessible. Now a panel of experts from NASA, academia and industry has selected the top five teams to share a $100,000 prize in the Phase 3: Level 1 of the competition.
Today, nearly 15 years since that last very close approach, Mars is making its another similarly close approach.
