Mission Mars Hope or Mission of Emirates Mars (Arabic: ????????? ?) is a space exploration investigation mission to Mars, to be launched by the United Arab Emirates in 2020. Once launched, it will be the first mission to Mars by an Arab or Muslim majority country. The mission was announced by Sheikh Khalifa bin Zayed Al Nahyan, President of the United Arab Emirates, in July 2014, and aimed at enriching the Emirates engineer's abilities and enhancing human knowledge about the atmosphere of Mars. This mission is being undertaken by a team comprised solely of Emirates engineers, and is contributing to a knowledge-based economy in the UAE.
Under the Emirates Mars Mission, the United Arab Emirates will send probes not released to Mars by 2020. The probe has been named the Hope probe or 'Al-Amal' and is scheduled to reach Mars in 2021, which coincides with 50th anniversary of the formation of the United Arab Emirates.
To achieve the objectives of the Mission of the Mars of Mars, the agreement was signed between the UAE Space Agency and Mohammed bin Rashid Space Center (MBRSC), under the direction given by His Holiness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of UAE and Dubai Ruler. Under the agreement, the Emirates Mars Mission will be funded by UAE Space Agency and will also oversee the complete execution process for the Hope probe. The agreement outlines the joint financial and legal framework by setting a timeline for the entire project.
Under the agreement, MBRSC has been commissioned to design, manufacture and launch the Hope probe. A team of more than 150 Emirate engineers at MBRSC is currently working on probes and other areas of the Emirates Mars Mission.

Overview
The spacecraft orbiter is an unplanned mission to Mars by the United Arab Emirates to study the atmosphere and climate of Mars. The Hope Probe is expected to be launched in the summer of 2020 and will take seven to nine months to arrive on Mars. In designing the orbiter, Mars Mars project deputy mission and mission manager Mars Sarah Al Amiri is expected to collaborate with the University of Colorado, the University of California, Berkeley and Arizona State University.
The name Hope (Arab: al-Amal) was chosen because "it sent a message of optimism to millions of Arab youths", according to Sheikh Mohammed bin Rashid Al Maktoum, Ruler of the Dubai emirate for whom the space center leads, Mohammed bin The Rashid Space Center (MBRSC), from the United Arab Emirates, is named. The project manager is Omran Sharaf. The resulting mission data will be shared freely with over 200 institutions worldwide.
The Emirates Mars Mission team includes 150 Emirate engineers, with Omran Sharaf as Project Manager; Sarah Amiri, Deputy Project Manager; Ibrahim Hamza Al Qasim, Deputy Project Manager, Strategic Planning, and Zakareyya Al Shamsi, Deputy Project Manager for Operations.
The spacecraft will be launched from Japan using Mitsubishi Heavy Industries H-IIA launchers.
The Hope probe will be a compact and hexagonal structure, with a mass of about 1,500 kg (3,300 pounds) including fuel. The probe will be 2.37 m wide and 2.90 m high, the overall size of which is roughly equivalent to a small car. Hope will use three 600 watt solar panels to charge the battery and will communicate with the Earth using a high gain antenna with a 1.5 m wide dish. The spacecraft will also be equipped with star tracking sensors that will help determine its position in space by identifying the constellations in relation to the Sun. Two sets of rocket booster and four to six large Delta-v pushers, will control the speed of the probe; and eight to 12 small reaction system boosters (RCS) will be responsible for fine maneuvering.
The expected travel time of the Hope probe is about 200 days at speeds up to 40,000 km/h in the course of 60 million kilometers. Arriving on Mars, he will study the atmosphere of Mars for two years. Its unique placement in orbit around Mars will provide a new type of data to build a "holistic model" of the Martian atmosphere. This data is expected to provide additional data on atmospheric escape to a level where it is now too thin to allow liquid water to exist. The Hope Probe will carry three scientific instruments to study the atmosphere of Mars, which includes digital cameras for high-resolution color images, infrared spectrometers that will examine patterns of temperature, ice, water vapor in the atmosphere, and ultraviolet spectrometers that will study the upper atmosphere and traces of oxygen and hydrogen further into outer space.
By 2015, the content of conceptual instruments is:
- Emirates Exploration Imager (EXI), to measure the nature of water ice, dust aerosols and ozone (O 3 ) measurements in the atmosphere.
- Emirates Mars Ultraviolet Spectrometer (EMUS), to measure global characteristics and thermosphere variability, and hydrogen and corona oxygen.
- Emirates Mars Infrared Spectrometer (EMIRS), to measure global thermal structures and the abundance of ice water, water vapor and dust in the atmosphere.
A prototype of the spacecraft Hope is shown on the Dubai Airshow in November 2017. This prototype is a model built to give a general idea of ​​what the spacecraft looks like. The project manager, Omran Sharaf, said the mission would be launched in July 2020.

Scientific objectives
The scientific goal for the Emirates Mars Mission, as approved by the global Mars science community, aims to provide a complete picture of the atmosphere of Mars.
The Hope Probe will study Martian atmospheric layers in detail and will provide data for study: the reasons for the drastic climate change in Mars's atmosphere since then can maintain liquid water to this day, when the atmosphere is so thin that water can only exist as ice or steam, to help understand how and why Mars lost its hydrogen and oxygen into space, and the relationship between Marsia's upper and lower atmosphere. Data from the Hope probe will also help to model the Earth's atmosphere and study its evolution over millions of years.
All data obtained from the mission will be available to 200 universities and research institutes worldwide for the purpose of sharing knowledge.
The probe will also serve research on the possibility of cultivating dates and lettuce on the planet Mars, according to German Emirate researcher Salem Al Ketbi.
Social interests
The leaders of the United Arab Emirates consider the Mission of the Mars emirate as an investment in the economy and human capital in the UAE. HH Sheikh Mohammed bin Rashid Al Maktoum attaches three important messages to his mission when he announces it: "The first message is for the world: that Arab civilization once played a huge role in contributing to human knowledge, and will play that role again: The second message is for the brothers we are in Arabia: that nothing is impossible, and that we can compete with the greatest nations in the race for knowledge and the third message is for those who seek to reach the highest peak: do not limit your ambitions, and you can reach even into space. "
The International Astronomical Congress 2020 will be held in Dubai, a few days after the expected launch of the Mars Missions.
Probe
Untrained probes to be sent to Mars under the Emirates Mars Mission have been named 'Hope' or Al-Amal in Arabic (Arabic: ??????? ?), for sending a message of optimism to millions of Arabs around the world and driving them toward innovation. In April 2015, H.H Sheikh Mohammed bin Rashid invited the Arab world to name the probe. The name was chosen after receiving thousands of suggestions, as it illustrates the core purpose of the mission. The probe's name was announced in May 2015 and since then, the mission is sometimes referred to as the 'Mission of Hope of Mars'.
Specifications
The Hope probe will be hexagonal, built from aluminum in a stiff but lightweight honeycomb structure with composite face sheets. With an estimated mass of 1500 kg including fuel, the overall size and dimensions of the probe will be comparable to that of a small car.
- Dimensions: The probe will have a width of 2.37 m and a length of 2.90 m
- Mass: The probe mass estimate would be 1500 kg
- Resources: The aircraft will charge the battery using 600-watt solar panels. The array of solar panels will be folded at launch and they will be revealed after the probes are in orbit
For communication purposes, high gain antennas with 1.5 m wide disks will be used by the probe. This antenna will produce narrow radio waves that should lead to Earth. There will also be a low gain antenna in the probe structure that will be less directional than the high gain antenna.
The probe will also have a star tracker to help determine its position in space by studying the constellations in relation to the sun.
It will be equipped with two sets of rocket propellers, which include four to six large Delta V 'pushers and eight to 12 small Control System Reaction (RCS) drivers. The 'Delta V' driving function is speed management, slowing down the probe or accelerating it as needed, while RCS boosters will be used for fine maneuvers. The reaction wheel in the probe will allow it to reorient itself while traveling through space, helping to direct the antenna toward the Earth or direct any scientific instrument to Mars.
Scientific instruments
To achieve the scientific objectives of the Emirates Mars Mission, the Hope probe will be equipped with three scientific instruments.
- Emirates eXploration imager (EXI): Measures the properties of water, ice, dust, aerosols, and ozone abundance in the atmosphere of Mars.
- Emirates Mars Ultraviolet Spectrometer (EMUS): Measuring global characteristics & amp; thermosphere and hydrogen & amp; oxygen corona.
- The Emirates Emirates Infrared Spectrometer (EMIRS): Check the temperature patterns, ice, water vapor and dust in the atmosphere.
Launch Window
The mission probes of the United Arab Emirates will arrive on Mars by 2021. To achieve this, rockets must be launched during a short launch window in July 2020. This is important because Earth and Mars will be parallel to enable the most efficient. (or minimum energy) transfer between Earth and Mars. This alignment occurs every twenty-six months, so if this missed time missed the Emirates Mars Mission had to wait for the next Earth and Mars alignment.
Team
The Mission Team of the Mars of Mars is divided into seven groups including Wahana, Logistics, Operations Mission, Project Management, Science Education & amp; Outreach, Ground Station, and Vehicle Launch. The team is led by Omran Sharaf, who acts as Project Manager and is responsible for managing and supporting ongoing work related to the Mission of Emirates Mars.
Sarah Amiri is the Deputy Project Manager & amp; Lead Science Investigator, who leads the team in developing the mission objectives of the United Arab Emirates and aligns programs related to Hope probe instrumentation. The mission has been called has the potential to make a long term contribution to the economy of the United Arab Emirates.
