On February 9, the probe from the United Arab Emirates is scheduled to enter the orbit of Mars. The maneuver has a 50% chance of success and will be launched by Madrid. If the mission is successful, it will be the first to provide a complete, daily view of the entire planet’s weather system.
Since it was launched from Japan in July last year, it has taken 7 months and has travelled 493,500,000 kilometers. Sanda Hope From United Arab Emirates (UAE) Will reach Mars on February 9.It is expected to be inserted above the track 16:57 hours (Spain time), an operation is not without risks.
“This is the first Arab interplanetary mission, and the UAE will be Fifth nation (After the United States, Russia, the European Union and India) reach the red planet (China will do this in a day)”, emphasized the Sheikh Mohamed Bin Rashid, Vice President of the UAE and Ruler of Dubai, Twitter, But it also recognizes that the exploration “has a 50% success rate for entering Mars orbit, although we have achieved 90% of the goal of acquiring new knowledge.”
When the “Hope” approaches the orbit of the red planet, there will be a tense and critical half-hour, during which the spacecraft must change its speed from 121,000km/h So “only” 18,000km/h.
This brutal deceleration will be carried out in a completely autonomous manner with the help of propellants, because the delay between the radio signal and the earth will prevent the personnel responsible for the mission from intervening from the missile control center. Emirates Mars mission (EMM) In Dubai. Similarly, about ten minutes after the operation, the probe will hide behind Mars.
“This Insert Mars orbit (I, This is one of the most risky stages of the mission, because this will be the first time we have turned on six Delta-V thrusters (at least four must work) for such a long time. System: 27 minutes (starting from 16 minutes): 30 Peninsula Time)”, he was in Internet Conference Omran Sharaf, The EMM project manager, he recalled that one of the requirements they had to meet was “Build but don’t buyThese systems.
Antenna Deep space communications complex MadridThe commander in Robledo de Chavela will be responsible for receiving signals during this critical phase to confirm the success of the mission. Later, as the earth rotates, other sites in Canberra (Australia) and Goldstone (U.S.) will take over communications.
“All the antennas of the deep space network will work, depending on the time of day and the relative position of each antenna with respect to Mars, but we will be in contact with it during the orbit insertion process, and it will be in contact with Contact. With someone from Madrid”, confirm with SINC Hessa Al Matroushi, The scientific director of the mission.
Complete Mars weather system analysis
Al Matroushi emphasized that Hope’s discovery on Mars will be truly unique: “This will be the first mission to provide a complete and daily view of the weather system in all regions of the planet. In particular, it will observe the climate and Climate change. The dynamics of the entire Martian surface, all periods of the day, and all seasons of the entire Martian year (equivalent to two on Earth) and the connection between the upper atmosphere and the lower atmosphere”.
The scientific director pointed out that when performing this mission, they have to answer many questions: “How does the low-level Martian atmosphere react to the atmosphere on a global scale, during the day and throughout the season. force How does the state of the sun and the planet’s entire atmosphere affect the escape rate of the atmosphere, and how does the Martian stratosphere behave in time and space…?
“He added that ultimately, we hope that by better understanding the atmospheric dynamics of Mars, we can better understand our own planet and other planets in our universe.”
To meet its goals, craftsmanship, size and weight of the SUV 1.350 kg (Including 800 kg of hydrazine as fuel), it has Three scientific methods.one is Camera EXI, It can capture high-resolution images and record the amount of ice, water and ozone in the Earth’s lower atmosphere.
The other two are spectrometer: Amis, It measures the global distribution of dust, ice clouds and water vapor in the lower atmosphere of Mars, and EMUS, Used to quantify the changes in the oxygen and carbon monoxide in the thermal layer and the hydrogen and oxygen content in the upper atmosphere.
Every time the data collected from the elliptical orbit is completed 55 hours They are located between 20,000 and 43,000 kilometers and can be used by scientists all over the world. Although before entering this stage, the instrument will be initially calibrated and adjusted until April.
It takes 13 to 26 minutes for a radio signal with information to reach the earth from hope. The contact time with the Emirates Control Center is limited to 6 or 8 hours twice a week. By then, new data on the Martian atmosphere and its dynamics is expected to exceed 1 terabyte.

In addition to its scientific purpose, the construction of Hope also helps to accelerate the pace of human development. Development of the aerospace sector In its originating country, the ship reached the Red Planet, which coincided with the 50th anniversary of the founding of the United Arab Emirates.
He emphasized at the meeting that this is about “developing capabilities and transferring them to the private sector to create new businesses that affect the economy.” Internet Conference Sarah Al Amiri, Senior Minister of Science and Director of the UAE Space Agency.
Al Amiri admitted: “From the first day, we knew that only half of the missions were successful, especially at the critical moment of entering the orbit of Mars. “Young people can work in space and other related departments.”
In this sense, those responsible for the Emirates mission to Mars also They organized parallel educational and promotional activities to increase the interest of young Emirati in science and technology.
Arab women’s STEM rises
“In the UAE, more than 70% of university graduates are women, and more than half of those trained in STEM (Science, Technology, Engineering and Mathematics) are also women. This is the result of the country’s vigorous efforts to promote the development of women. The field of science and technology”, Al Matroushi said.
He concluded: “So, through our space program, we have been able to highlight opportunities in this area, and there is no doubt that it has a significant impact because we represent 34% of the space team. Mohamed Bin Rashid Space Center (Multimedia Broadcasting and Television, This task has been completed) and 80% of the scientific team”.
Although the Hope probe has been designed and manufactured throughout the process Six years At MBRSC in the UAE, the project developed scientific instruments in cooperation with Colorado, California, Arizona and the University of Berkeley. In this very dangerous task phase, more than 450 professionals and Emiratis have participated in the meeting.
