British scientists have recreated the environment of the red planet to test out three prototype Mars rovers.
ITV News speaks to the British men and women shortlisted for a mission to establish a human colony on Mars.
India has successfully launched a controversial space rocket which it hopes to use to reach Mars.
India has successfully launches its first rocket to Mars, aiming to put a satellite in orbit around the planet at a lower cost than previous missions, thus potentially positioning the nation as a budget player in the global space race.
The mission is considerably cheaper than previous missions by the United States, Europe and Russia. Costing 4.5 billion rupees - (or approximately just £45.7 million) it is a fraction of the cost of an average NASA satellite mission.
However the mission has attracted criticism due to the high levels of poverty, malnutrition and power shortages suffered by millions across the country.
The UK currently gives India £280 million a year in financial aid, but this will end in 2015.
India's space agency has launched it first mission to Mars from the Satish Dhawan Space Centre in Sirharikota, near Chennai.
India's space agency to is counting down to launch its first ever rocket to Mars this morning.
Indian Space Research Organisation (ISRO) scientists have said the mission is primarily aimed at testing the best technologies to fly and orbit and communicate from the Red Planet.
If the mission is successful, and the satellite orbits the Red Planet, India's space agency will become the fourth in the world, after the US, Russia and Europe, to undertake a successful Mars mission.
The 56-hour countdown to launch started on Sunday.
Today's mission follows India's successful 2008-2009 Chandrayaan-1 moon probe, which discovered water molecules in the lunar soil.
India is counting down to its maiden voyage to Mars later today with its unmanned orbiter Mangalyaan, aka Mars Orbiter Mission.
It will take 11 months for the aircraft to reach the Red Planet, where it will conduct "meaningful scientific experiments" according to K Radhakrishnan, chair of the Indian Space Research Organisation.
Among the Mars Orbiter Mission's ambitious goals is a search for methane in the Martian atmosphere. On Earth, the chemical is strongly tied to life.
The evidence "seems to be building that we are actually all Martians" and "that life started on Mars and came to Earth on a rock," according to a scientist from The Westheimer Institute for Science and Technology in the US.
Professor Steven Benner said, "It's lucky that we ended up here nevertheless, as certainly Earth has been the better of the two planets for sustaining life. If our hypothetical Martian ancestors had remained on Mars, there might not have been a story to tell."
Prof Benner told the Goldschmidt 2013 conference in Italy that the oxidised mineral form of the element molybdenum, "couldn't have been available on Earth at the time life first began, because three billion years ago the surface of the Earth had very little oxygen, but Mars did".
"It's yet another piece of evidence which makes it more likely life came to Earth on a Martian meteorite, rather than starting on this planet," he added.
Life on Earth may have started on Mars, a major science conference has heard.
An element believed to be crucial to the origin of life would only have been available on the surface of the Red Planet, Geochemist Professor Steven Benner claims.
Professor Benner argues that the "seeds" of life probably arrived on Earth in meteorites blasted off Mars by impacts or volcanic eruptions.
He points to the oxidised mineral form of the element molybdenum, thought to be a catalyst that helped organic molecules develop into the first living structures, as evidence of his theory.
A NASA timelapse video shows its Curiosity rover's first year on Mars compressed into two minutes.
The robotic space vehicle, which began its Martian mission on 6 August 2012, is seen scooping up soil samples and drilling into rock on the Red Planet.
