Hope will now fly through space until it reaches its orbit around Mars in about seven months. What is Mission Hope expecting to find on Mars? .
The Hope spacecraft is equipped with three instruments - the Emirates Exploration Imager (EXI), the Emirates Mars Ultraviolet Spectrometer (EMUS), and the Emirates Mars InfraRed Spectrometer (EMIRS).
Omran Sharaf, the UAE Mars mission director, told journalists in Dubai that the probe was sending signals that would be analysed later but everything appeared good. The solid rocket booster successfully separated from the launch vehicle and established radio communication with the mission on earth. It will be the first interplanetary mission by a Middle Eastern country. The Emirates have also pledged to build the first human settlement on Mars by 2117.
The UAE already has nine functioning satellites in orbit, with plans to launch another eight in coming years.
The Emiratis involved in the program also acknowledged it represented a step forward for the Arab world, the home of mathematicians and scientists for centuries before the wars and chaos that have gripped wide swathes of it in recent times.
Seeing the probe blasting off was "an indescribable feeling", said Sarah Al-Amiri, the UAE Mars mission's deputy project manager.
While the mission objective is to provide a comprehensive image of the weather dynamics in Mars's atmosphere and pave the way for scientific breakthroughs, the UAE wants the project to serve as a source of inspiration for Arab youth, in an often volatile region.
The UAE, which has a population of around 9.4 million, announced plans for the mission in 2014 and launched its National Space Programme three years later. NASA's Curiosity rover has been exploring Mars since 2012.
Most Mars missions orbit at a single local time that allows the atmosphere to be measured at only one time of day but Hope Probe will circle Mars for the entire Martian year, which is equivalent to nearly two Earth years, the report said.
Al Amal, or Hope Probe, weighing 1.3 tonnes was launched from the H-2A rocket from Japan's remote Tanegashima spaceport at 1.58 am local time.
There are now eight active missions exploring Mars; some orbit the planet and some have landed on its surface. - Reuters An Emirati man prepares to watch the launch of the Hope Probe at the Mohammed bin Rashid Space Center in Dubai on July 20. Japan has its own Martian moon mission planned for 2024.
