The first Arab space mission to Mars, an unmanned probe dubbed "Hope", has blasted off from Japan, in a bid to reveal more about the atmosphere of the Red Planet.
The Japanese rocket carrying the probe developed by the United Arab Emirates (UAE) lifted off from the Tanegashima Space Centre in southern Japan right on schedule at 6:58 am local time.
The launch of the probe, known as "Al-Amal" in Arabic, had twice been delayed because of bad weather, but the lift off appeared smooth and successful.
Almost exactly one hour later, a live feed showed people applauding in the Japanese control room as the probe successfully detached.
"The launch vehicle trajectory was executed as planned and separation of the Hope spacecraft was confirmed," rocket manufacturer Mitsubishi Heavy Industries said.
In Dubai, the launch was met with rapturous excitement, with the Burj Khalifa - the world's tallest skyscraper - lit up hours before lift off with a symbolic 10-second countdown in anticipation.
"This mission is an important milestone for the UAE and the region," said the director of the UAE's Mohammed bin Rashid Space Centre, at a post-launch press conference in Japan.
"It has already inspired millions of youth regionally to dream big and work hard to achieve what seems to be impossible," he said.
The Emirati project is one of three racing to Mars, including Tianwen-1 from China and Mars 2020 from the United States, taking advantage of a period when the Earth and Mars are nearest.
In October, Mars will be a comparatively close 62 million km (38.6 million miles) from Earth, according to NASA.
"Hope" is expected to enter Mars orbit by February 2021, marking the 50th anniversary of the unification of the UAE, an alliance of seven emirates.
Unlike the two other Mars ventures scheduled for this year, it will not land on the Red Planet, but instead orbit it for a whole Martian year, or 687 days.
While the objective of the UAE's mission is to provide a comprehensive image of the weather dynamics, the probe is a foundation for a much bigger goal - building a human settlement on Mars within the next 100 years.
Dubai has hired architects to imagine what a Martian city might look like and build it in its desert as "Science City", at a cost of around $135 million dollars.
The UAE also wants the project to serve as a source of inspiration for Arab youth, in a region too often wracked by sectarian conflicts and economic crises.
On Twitter, the UAE's government declared the probe launch a "message of pride, hope and peace to the Arab region, in which we renew the golden age of Arab and Islamic discoveries."
Several dozen probes, most of them American, have set off for the Red Planet since the 1960s. Many never made it that far, or failed to land.
The drive to explore Mars flagged until the confirmation less than ten years ago that water once flowed on its surface.
