Onlookers view Mars at its closest to Earth in 15 years

In contrast, Mars is normally about 225 million kilometres away from Earth.

On July 27, Mars was at opposition, meaning that the Sun and the Red Planet came opposite to each other, keeping the Earth in the middle.

Mars features a very thin atmosphere, which translates to men quickly dying from one of the following four causes: 1) lack of sufficient atmospheric pressure to prevent organs from rupturing out of the body, 2) suffocation from lack of oxygen 3) freeze from low temperatures, or 4) get fried from too much ultraviolet radiation.

Greenhouse gases such as carbon dioxide (CO2) would be vital to do this, but they are not present on Mars in high enough quantities to provide any significant greenhouse warming, said Dr Bruce Jakovsky.

Terraforming - that is, making an inhospitable planet comfortable enough that humans could settle on it without living in domes - is a concept that was popularized long ago by science fiction and while we might some day have a system for turning planets like Mars into more Earth-like homes for humanity, that's still a long ways off.

The last closest approach was in 2003 when Mars was 34.6 million miles (55.7 million kilometers) from Earth "and the closest it had been in almost 60,000 years", said NASA.

If you can't attend, you will likely be able to see it without a telescope.

Mars will be the bright reddish star below the moon, near the horizon. Although studies investigating the possibility of terraforming Mars have been made before, the new result takes advantage of about 20 years of additional spacecraft observations of Mars.

UAE stargazers will get the chance to see the planet Mars in the night sky as it will be clearly visible to the naked eye.

Mars approaches Earth once every two years and two months.
