The United Arab Emirates' first mission to Mars has reached the red planet and entered orbit after a seven-month, 494 million km journey, allowing it to start sending data about the Martian atmosphere and climate.

This makes the UAE the fifth space agency to reach the planet.

The Mars program is part of the UAE's efforts to develop its scientific and technological capabilities and reduce its reliance on oil.

The UAE Space Agency even has a plan for a Mars settlement by 2117.

"Contact with HopeProbe has been established again. The Mars Orbit Insertion is now complete," the Mohammed Bin Rashid Space Centre (MBRSC) said in a tweet.

The attempt to lock into orbit around Mars had a 50 per cent chance of failing, Dubai's ruler and UAE Vice President Sheikh Mohammed bin Rashid Al Maktoum said on Tuesday.

"This is the farthest point in the universe to be reached by Arabs throughout their history... Our goal is to give hope to all Arabs that we are capable of competing with the rest of the world," he said.

To enter Mars' orbit, the probe needed to burn around half its 800kg of onboard fuel to slow down enough not to overshoot.

This year marks 50 years since independence from Britain and the founding of the UAE.

Mars probes launched by China and the US just after the UAE's lift-off in July are also set to reach the planet this month.

The Emirates Mars Mission, which has cost about $US200 million ($A259 million), launched the Hope Probe from a Japanese space centre.

It aims to provide a complete picture of the Martian atmosphere for the first time, studying daily and seasonal changes.

The UAE first announced plans for the mission in 2014 and launched a National Space Programme in 2017 to develop local expertise.

Hazza al-Mansouri became the first Emirati in space in 2019 when he flew to the International Space Station.
