Mars is already brighter than usual and will shine even more- and appear bigger - as Tuesday nears.
The red planet will be just 35.8 million miles (57.6 million kilometers) apart on Tuesday.
Mars' approach to Earth was broadcast over the internet this morning from the LA-based Griffith Observatory.
During opposition, Mars is especially photogenic because it can be seen fully illuminated by the Sun as viewed from Earth. Because a Mars year and Earth year take different amounts of time, their orbits will soon desynch and the planets will separate.
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 U.S. agency said in a statement.
NASA's Mars Science Laboratory mission, Mars Curiosity took to Twitter and wrote,"I feel so close to you right now". And if you miss it this time around, you'll have to wait another 269 years before it comes around again.
A very thin atmosphere still exists around the planet, but it's less than one percent as dense as ours on Earth.
Another close encounter like 2003´s will not happen until the year 2287. In the video, you can see telescopic imagery of the Red Planet, conversations between scientists as they observe the night sky, and guest appearances by a number of people, including "Star Trek: Voyager" actor Tim Russ, and former NASA astronaut Buzz Aldrin. Additionally, gravitational pull of the planets within our solar system constantly affects the shape of their orbits, moving Mars' orbit even closer to the Earth. Mars will still be visible in the night sky for the next few months.
"Our results suggest that there is not enough Carbon dioxide remaining on Mars to provide significant greenhouse warming were the gas to be put into the atmosphere", said Dr Jakobsky from the University of Colorado and the lead author of the study, which was published in Nature Astronomy.
