Watch: UAE Hope Probe Mission to Mars, all you need to know

Dubai: The UAE launches the Arab world’s first mission to Mars in the early hours of Monday, but why and what for? Here are the particulars of this latest space venture from the nation that put its first astronaut into space just ten months ago.

What is the Hope Probe?

The UAE’s Hope Probe (Al Amal in Arabic) is the first Arab interplanetary mission. It is designed to orbit Mars and provide the first-ever complete picture of Martian atmosphere.

Hope Probe will begin its journey to Mars in the early hours of July 20 at 1:58am (UAE time) from Japan’s Tanegashima Space Centre (TNSC) aboard Mitsubishi Heavy Industries’ H-IIA rocket. This is the third rearrangement of the launch after cancellations due to rain on July 15 and July 17.

The date is within the so-called launch window that lasts for about a month every two years when Earth and Mars are closest together.

His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai, said Hope Probe is an accomplishment for every Arab and a source of pride for every Emirati. Sheikh Hamdan Bin Mohammed Bin Rashid Al Maktoum, Crown Prince of Dubai and Chairman of Dubai Executive Council, added that it represents a message of hope and optimism to mankind. The space mission is aimed at serving humanity.

Why study Mars?

Hope Probe is expected to collect more than 1,000GB of new data, which will be shared with more than 200 academic and scientific institutions around the world for free.

By studying the connection between current Martian weather and the ancient climate of the Red Planet, scientists will have deeper insights into the past and future of the Earth as well as the potential for human settlement on Mars and other planetary objects.

Scientists will understand the weather and learn how Mars lost some of its atmosphere over billions of years of its planetary history. Substantial geophysical evidence suggests that Mars was once a much warmer and more humid world, with a lot of liquid water on its surface that could have been optimal for some form of life to evolve.

Why is UAE sending a spacecraft to Mars?

To improve the quality of life on earth by pushing the limits to make new discoveries; to encourage global collaboration in Mars exploration; to demonstrate leadership in space research; to build Emirati capabilities in the field of interplanetary exploration; to build scientific knowledge; to inspire future Arab generations to pursue space science; to establish the UAE’s position as a beacon of progress in the region.

How long will the mission be?

Mars rotates on its axis, completing one rotation every 24.6 hours. Martian days are called Sols (short for solar day). Hope Probe will orbit Mars for one whole Martian year that lasts 669.6 sols or equivalent to 687 Earth days or about two Earth years.

Hope Probe will have two years of science operations beginning May 2021, with a possibility of extending until 2025.

How long is the journey from Earth to Mars?

It will be a 495-million kilometre journey to reach and orbit Mars. The voyage will take around 200 days at a cruising speed of 121,000km/hour.

Hope Probe is expected to enter Mars’ orbit in February next year, coinciding with the UAE’s golden jubilee celebrations.

Who built Hope Probe?

Hope Probe was built by a team of 150 Emirati engineers who collaborated with American engineers and scientists at three US universities, including University of Colorado, University of California Berkeley and Arizona State University.

It cost around $200 million (Dh735.6 million), which is considered among the lowest in the world when compared with similar programmes.

The Mohammed Bin Rashid Space Centre (MBRSC) has been responsible for the execution and supervision of all stages of the design, development and launch of the spacecraft while the UAE Space Agency is funding and supervising all procedures.

Hope Probe timeline

Hope Probe specs and speed

Hope Probe is a compact spacecraft whose overall size and weight are comparable to a small car. It weighs 1,500kg when fuelled up. Its structure is cubical, it’s made out of aluminium with a composite face-sheet. It measures 2.37 metres wide and 2.9 metres long, while it is 3 metres X 7.9 metres when the two solar panels are stretched wide open.

It has two solar panel wings affixed to the top platform that will provide 600 watts to charge batteries of the spacecraft.

It has a 1.5 metre high-gain directional dish antenna to allow communication rates of 1.6Mbps at the minimum, Earth-Mars distance to 250 kbps at its furthest point. There are also three low-gain antennas.

Hope Probe will blast off from Earth aboard a launcher rocket before it detaches and accelerates into deep space. It will reach a speed of 126,000kph on its 495-million km journey to Mars, which will take around 200 days.

Propulsion is provided by four to six 120-N thrusters mounted on the bottom of the spacecraft while positional and orientation knowledge is provided by star trackers and coarse Sun sensors.

How Hope Probe will study Mars?

Hope Probe will study the Martian atmosphere from a science orbit of 20,000 km periapsis (the point which it is nearest to the body that it orbits) and 43,000 km apoapsis (the high point in an orbit), with an orbital period of 55 hours and an orbital inclination of 25.

No other Mars spacecraft has had such an orbit; most orbit at a single local time that allows the atmosphere to be measured at only one time of day but Hope Probe will do this for the entire Martian year.

Three advanced scientific instruments are mounted on Hope Probe that will work simultaneously to observe Mars atmosphere.

Why explore the Red Planet?

Mars is the second-smallest planet in the solar system and the fourth planet from the sun. Other than our Earth, Mars is the most explored planet in our solar system.

Humans have been exploring these fundamental questions: Did Mars once have life on it? What is the climate history of Mars? How did Mars evolve from its original state? Should Mars be the next destination for humans?

Mars is also called the ‘Red Planet’ because it appears in the sky as an orange-red star. But the planet’s appearance is actually due to rust in the Martian rocks.

Nothing compares to the harsh environment of Mars. However, there are a few places on Earth that can give us a glimpse of the Martian environment. These are Death Valley in California, Haughton Impact Crater in Canadian High Artic and volcanoes in Hawaii.

Mission (im)possible

Unmanned missions to Mars began in the 1960s. There have been 56 Mars missions so far, of which only 26 have been successful — a testament to the difficulty in reaching the Red Planet.

There are currently eight active Mars Missions, but Hope Probe is the first Arab interplanetary exploration.

Here are some of the earlier Mars missions

There are seven confirmed missions, including Hope Probe, through 2024, and at least a dozen until mid-2040s. Here are some of them:

What happens on launch day?

A team of Emirati engineers is stationed at Tanegashima Space Centre and another group will be at the mission control room inside the Mohammed bin Rashid Space Centre in Dubai.

Hope Probe will be carried by a 53-metre long and 289-tonne H-IIA rocket (launch vehicle No. 42) manufactured by Mitsubishi Heavy Industries.

Weather will play a crucial role during the launch. Several rocket launches have been postponed in the past due to inclement weather. There will be an hourly weather check during launch day to determine the go/no-go decision for the launch.

After final checks and getting the go signal, the two-stage rocket will blast-off from the launch pad at 1,100 kilonewtons of thrust. It will soar up at speed of up to 34,082km/hour.

The rocket fairing (nose cone) will be jettisoned and around one hour after launch, the spacecraft (Hope Probe) will separate from the launcher, and around six to eight minutes after separation, Hope Probe will deploy its solar panels. These panels will be adjusted so they point towards the sun and start collecting power to charge the batteries.

Approximately 30 minutes after separation, Hope Probe will send its first signal from space to the operations room at MBRSC, via an antenna in Madrid, which is part of the Deep Space Network communications system.

MBRSC will check the health of Hope Probe and ensure the solar panels are facing the sun properly.

The operations centre in Dubai will then be able to control Hope Probe remotely as it makes way to the Red Planet.

Where to watch?

The launch of Hope Probe will mark as the first time in space exploration history that the countdown for a space mission will be done in Arabic.

Hope Probe's journey to Mars will be streamed live on https://www.emiratesmarsmission.ae/live/.

Will it return to earth?

It will not return. There is no provision that will carry it back to Earth. Hope Probe is set for one Martian yearorbit (around two Earth years or until 2023) but according to Emirates Mars Mission, Hope Probe may extend its science mission at Mars beyond 2024.

Also, Hope Probe will not bring pieces of Mars to Earth but will transmit 1 Terabyte of Martian atmosphere information.     

Meet the people behind the Hope Probe

Six years of perseverance and technological innovation will come to fruition as the UAE’s Hope Probe, the first Arab interplanetary mission, begins its journey to the Red Planet in the early hours of July 20.

Hope Probe (Al Amal in Arabic) will study the planet’s entire atmosphere and the UAE will become only the fifth country in the world to orbit Mars.

Over 200 Emirati engineers, scientists and analysts have collaborated on Hope Probe since it was first announced by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, back in 2014.

Here, we look at some of the men and women – the faces of Hope – who helped build more than a spacecraft but also a “beacon of hope” for all the people of the region to revive a rich history of Arab and Islamic achievements in science.

They have answered the call to build an Emirati space program and helped forge a promising future for humanity from the desert sands of the UAE to Mars and beyond.

Mariam will study the data and scientific information that will be collected by Hope Probe and made available to everyone via the Emirates Science Data Centre.

She said once the probe begins its mission to explore the Martian atmosphere, the data obtained will be compiled by the Emirates’ Scientific Data Centre and will be available to the international scientific community, “to help them understand the climate and the reasons why the Red Planet has lost part of its atmosphere”.

Hessa Al Matroushi - Science data and analysis lead

Omar Al Shehhi - Lead for integration and testing of Hope

He said: “From the onset of the project, we began working on the designs of electrical and mechanical ground equipment, starting with planning tests on the satellite, and the environments that the Probe faces at different stages, such as the vibrations resulting from the launch environment, high and low thermal environment in space, and the assembly and installation of the probe in coordination with different teams.

Mohamed Al Ameri - Senior Space Mechanical Systems engineer

His main responsibilities range from design of spacecraft components structure to withstand the space environment with a focus on strength, stiffness, thermal stability, and manufacturability requirements. He is also the Spacecraft lead for the Arab Cooperation Satellite 813 (Hyperspectral Satellite). He has a bachelor’s degree from the University of Utah in the US, in Mechanical Engineering.

About his work for the mission, he said: “We meet every morning and share tasks according to a schedule. Each of us works on a set of tasks according to the diversity of responsibilities approach that we have trained on and which qualified us to deal with a wide range of tasks in different disciplines. “

Issa Hareb Al Mheiri - Energy Systems Engineer

Issa was responsible for installing the solar panels that will collect renewable and solar energy and power the batteries of Hope Probe.

He said: “The challenge lies in storing the solar energy when the Probe reaches and starts orbiting the Red Planet when the sun disappears at certain times. The importance of these batteries becomes vital then. I will also be tasked with ensuring that all the Probe’s batteries are fully charged before the launch date.”

Ahmad Obaid Al Yammahi - Assembly and Mechanical Systems Engineer

Ahmad provided support to the team during the shipping operation of the satellite. He was with the team at the Nagoya Airport in Japan to receive and transport the satellite and surround it with nitrogen gas to protect its stability and systems.

He shared: “I have utilized my installation and mechanical assembly experience that I gained from my previous work on the KhalifaSat project to support my colleagues today in the Hope Probe team and ensure best preparations.”

Mahmoud Al Awadi - Mechanical Systems Engineer

Mahmoud worked with the team that designed Hope’s structure. He also did the installation and assembly and conducted tests to ensure the safety of the probe and its scientific equipment.

He said of his task: “We ran many tests to ensure the safety and readiness of the fuel tank and make sure that there are no leaks in the propulsion systems network since we use hydrazine as a fuel for the probe, which is a very sensitive material.”

Youssef Al Shehhi - Thermal Systems Engineer

He was supposed to be at Tanegashima for no more than two weeks but due to the coronavirus pandemic, he decided to stay and support the team in receiving and moving the probe and testing the devices to ensure their safety and help install the thermal insulator that protects the probe from the space environment.

He said: “The project’s thermal systems are a challenge because the Probe will go through very hot temperatures at the launch to very cold temperatures when it reaches Mars. So, we designed the thermal systems and tested them under extremely low and high temperatures.”

Mohammad Omran Al Ameri - Ground Support Engineer

Mohammed joined the Probe Hope project in 2016 with a task to make sure that the probe’s systems are correctly integrated and assembled. He also helped design and make ground support equipment, such as the equipment that help integrate scientific devices on the probe to control its movement and direction accurately.

About his task, he shared: “We moved the probe after receiving it in Japan and installed mechanical equipment. We then measured its weight and central mass before and after refueling to make sure it’s ready. I also helped prepare the solar panels on the mechanical level and how they can be correctly folded in low and high temperatures since the probe will face both types of temperatures.”

Khalifa Al Mheiri - Satellite Telecommunications Engineer and Communication Subsystem Lead

Khalifa worked since 2016 within the Probe communications design group to ensure the integrity of communication throughout its journey from Earth to Mars.

His task is to receive all information from the Probe and send orders to it from the Earth station at MBRSC.

He said: “The frequency and the communication wave must be calculated precisely along with the electromagnetic radiations especially since the process of sending or receiving communication data with the Probe takes anywhere from 13 to 20 minutes due to the distance. We designed communications systems that make the data work within the correct frequency and at the correct speed to comply with the international standards approved by the International Telecommunication Union.”

He headed the communications unit of the space engineering department at MBRSC in 2018. He graduated from the American University of Sharjah with a Bachelor’s in Electrical Engineering.
