The probe sent by the United Arab Emirates to the red planet has been successfully inserted into the planned orbit, becoming the first interplanetary mission of an Arab country. Its scientific purpose is to study the meteorological changes throughout the Martian year.
According to the plan, at 4:57 PM Spanish Peninsula time, Sanda Hope The person in charge of this mission confirmed that (Esperanza in Spanish or Al-Amal in Arabic) has reached the orbit of the Red Planet. United Arab Emirates (UAE), Thus becoming the fifth country or space power (after Russia, the United States, Europe and India) to do so.
The incident occurred the day before China sent the Tiantian-1 spacecraft into Mars orbit, and a week after NASA’s “Perseverance” carrier rocket landed on its surface on February 18.
Hope had to run her six Delta-V thrusters for 27 minutes to reduce cruising speed. From 121,000 km/h to approximately 18,000 km/h It has been allowed to implement track insertion. Since there is a delay of about 11 minutes between the radio signal with the earth, it is impossible to manage the direct operation, so the operation has been carried out in the autonomous system.
“Into the orbit of Mars has The most critical and dangerous part of the missionHe said: “Because of the unprecedented pressure and pressure to detect,” he said. Omran SharafProject manager of Mohamed Bin Rashid Space Center (MBRSC).
“Although we spent six years designing and conducting tireless tests, we couldn’t fully simulate the effects of the deceleration and navigation required to automatically achieve the insertion,” added Sharaf, emphasizing that they were entrusted to “Build but don’t buysystem.
For its part, Sarah Bint Yousef Al AmiriThe UAE Minister of Advanced Technology and Director of the UAE Space Agency recalled that the probe arrived on Mars on its second anniversary: “In 2021, we will commemorate Emirates’ 50th Anniversary, Is also half a century since the first man-made object landed on the red planet ( The Soviet Union probed Mars in 19713). For us, this marks the UAE’s continued orientation of its economy towards the future of research, the importance of science and technology”.
Learn Meteorology in the Year of Mars
Now Hope will maintain that orbit, calibrate and test its research instruments, and then enter its appropriate scientific orbit, from which it will provide the first complete picture of red planet meteorology in the entire Martian year (687 Earth days).
Hessa Al MatroushiThe mission science director of MBRSC explained that the spacecraft will describe the elliptical orbit of Mars in the next two years, “allowing analysis of the Earth’s atmosphere through different stations and its scientific instruments in different ways, in different ways., This will explore different Atmospheric coverage Establish a new global perspective of their behavior and connections”.
In the next two months, Hope will conduct instrument and system tests that will move in an elliptical orbit between 1,000 and 49,380 kilometers above the surface of Mars. After the data verification and testing phase, after browsing the track for about six weeks, April 2021, Scientific exploration will begin.
The probe has a 20,000-43,000 km elliptical science orbit, It will be completed every 55 hours, and global planetary images will be obtained every 9 days.His three musical instruments One high-resolution camera and two spectrometers (one infrared and one ultraviolet), which will allow us to study the changes in Martian climate between high and low altitudes and complete the first image of atmospheric dynamics and planetary climate at all times of the day and throughout the season.

When developing scientific instruments, UAE engineers rely on Cooperation and suggestions from American colleagues Worked in Colorado, California, Arizona and Berkeley University.All in all, the cost of the project is about $200 million.
first of all data The report of the mission will be released in September and made available to The scientific community International. After that, the survey results will be submitted in early December.
According to its promoters, the mission is to Accelerate innovation and scientific research in the UAE,as well as Inspire the younger generation Study science and technology careers in the Middle East.
