Building Rashid

Inside the Dubai lab where the first Arab lunar rover is being brought to life

Inside a small robotics lab on the outskirts of Dubai, a group of Emirati engineers spend long hours bringing the Arab world’s first Moon mission to life.

They are designing the Rashid rover, a 10-kilogram robotic explorer that will be launched from Earth late next year with the aim of landing on the lunar surface.

The UAE's latest extra-terrestrial mission is set to take the country's space ambitions – born 45 years ago, when Sheikh Zayed, the country's Founding Father, met American astronauts who had travelled the Moon – to new heights.

Some of those dreams have already been realised with the successful arrival of the nation's Hope probe to Mars in 2021, the completion of 2019's week-long journey into space by Hazza Al Mansouri, the first Emirati astronaut, and the domestic construction of several satellites.

Emirati engineering is now being put to a new test with the construction of a robot that must operate on the surface of another celestial body. The rover will need to overcome several challenges, including the unpredictable lunar terrain and the Moon's ever-changing conditions.

The National visited Lab 37 in Dubai Technology Entrepreneur Campus, Silicon Oasis, where a core team of 11 engineers from the Mohammed bin Rashid Space Centre are working to achieve the historic feat – previously accomplished only by the US, the former Soviet Union and China.

The final prototype of the rover is complete and undergoing final testing.

Once finished, engineers will begin assembling the final version and ship it to ispace, a Japanese commercial space company that will carry the rover on its Hakuto-R lander. The mission will take off on a Falcon 9 rocket from the Kennedy Space Centre in Florida.

Using such a commercial lander means emerging space nations like the UAE get quicker access to the stars.

The Rashid rover will land on the near side of the Moon, at a site called the Lacus Somniorum, the Lake of Dreams.

Once again, the world will watch with bated breath as the UAE attempts another daring space mission.

Meet the team

The man in charge

One of the busiest people inside the lab is Hamad Al Marzooqi, an Emirati engineer who is leading the mission.

The 38-year-old, who has a doctorate in electrical engineering from Khalifa University, joined the space centre six years ago and previously worked on KhalifaSat, the first Emirati-built satellite.

As project manager of the Emirates Lunar Mission, Dr Al Marzooqi believes accomplishing the daunting task will further encourage young Emiratis to pursue careers in space – like the Apollo mission did for young Americans.

"One of the outcomes that was very visible from the Apollo era was something called the Apollo effect. It was a generation that believed science and technology were the future because they had seen astronauts landing on the Moon,” he says.

“Instead of children having posters of singers or athletes in their bedrooms, they’d have posters of rockets and astronauts.

“We saw some of that momentum during our first mission to the International Space Station and then to Mars, and that was amazing. We think having a mission to the Moon would add to that momentum and the public’s interest in science and technology.”

Another outcome the space centre hopes to achieve through the Moon mission is to advance engineers’ skills in preparation for more complex landings in future.

The UAE intends to undertake several lunar missions, but Dr Al Marzooqi said the knowledge gained from this one could help with potential future plans to land on other celestial bodies.

“What we will gain from this mission will help us develop our capabilities and technologies so we can advance our current and future missions to the Moon or even plan for future missions to the surface of Mars,” he says.

But first the team has to overcome “thousands of challenges” to make the lunar mission a success.

Using a tiny rover comes with its own risks, including making sure it can survive the fluctuating temperatures on the lunar surface.

“When we started the mission, we thought: 'It’s a small rover, so it’ll be easy.' But it was very challenging and complicated,” Dr Al Marzooqi says.

“You’re working in an environment where temperatures vary from -100°C and go up to 120°C. That adds complexity to the thermal design of the robots.”

It is boiling hot on the Moon during a lunar day – about 14 Earth days – when it is experiencing sunlight. During a lunar night it is freezing cold.

The UAE’s mission has been designed for one lunar day, but the team is looking for ways to keep the rover alive throughout the night.

Receiving signals from Rashid

Millions of people across the world watched in suspense when the Apollo 11 astronauts landed on the Moon in 1969.

Since then, astronaut Neil Armstrong’s words – "That’s one small step for man, one giant leap for mankind" – have inspired many people.

The space centre is hoping for an Emirati version of an “Apollo moment” when the Rashid rover sends its first signal from the Moon and safely descends on to its surface.

First, the team must ensure the rover can communicate with ground control to receive signals and track mission progress.

That is where Dr Sara Al Maeeni, communication lead and project scientist with the mission, comes in.

The 35-year-old, who has a doctorate in communication engineering, is in charge of ensuring the communication subsystems – telecommunication between the rover, the lander or the ground station – are functional.

ispace will provide wireless communication between its lander and the rover, but the team is working on an experimental system that would provide a direct line between the rover and a ground station in Dubai.

“One of the communication systems is almost dependent on the lander. You can’t guarantee what could happen with the lander and if their communication system will work or not – that’s why we have redundancy communication, which is direct,” Dr Al Maeeni says.

“That one is an experimental system. It’s a very small communication subsystem and is very low-compact and [low-] energy – about two to four watts corresponding to the distance between Earth and the Moon, which is about 380,000 kilometres.”

Dr Al Maeeni is one of three other Emirati women who are part of the mission’s core team.

She says her four children were as excited as she is about the Rashid rover.

“They’re so proud of me,” she says. “I was speaking about space and the Moon once when I went to one of my kids’ classrooms, and I can’t forget my child’s reaction. My kids ask me every day about the mission.”

Designing the rover

Owing to the small size of the rover, every element of its design had to be carefully considered.

Abdullah Al Shehi, 30, the lead on the mechanical system, says the main challenge has been ensuring the systems, including electrical and thermal, can fit into the 10kg rover.

“We have worked with the 250kg and 300kg to 350kg structures before and the Mars mission was more than one tonne,” says Mr Al Shehi, who has a bachelor's degree in science in mechanical engineering.

“[The rover] is very small and we have mass constraint at 10kg for the full systems. So there are some other concerns that are coming from the electrical system and that puts a lot of challenges on the design itself.”

The first two designs of the rover were much bigger in comparison to the final version.

The team shrunk the structure because of size constraints in the envelope of the lander, where the rover will sit during launch and cruise.

Employed with the space centre since 2015, Mr Al Shehi previously worked on KhalifaSat and is also currently working on the MBZSat mission – another Emirati-built satellite.

“I’m very excited to work with the team. We’ve been working differently than how we do in the environment inside the space centre,” he says.

“The team is more diverse. It’s a small team, so the communication is very effective. We meet regularly and exchange ideas.”

The rover has four durable wheels to survive the Moon’s unstable terrain.

It has four cameras, two of which are high-resolution and were provided by the French space agency. The cameras will also assist with navigation.

The third camera will be microscopic, to capture close-up images of lunar dust. The final camera will study thermal properties on the Moon's surface.

Rashid will also have a Langmuir probe, which will measure the temperature of electrons, electron density and the electric potential of plasma.

An inertial measurement unit will track the rover’s movements.

The heart of Rashid

Arguably one of the toughest tasks has fallen to Ahmed Sharaf, electrical systems lead, who is working with his team to find a way to keep the rover alive during the lunar night.

“During the night the temperature gets really cold. We expect that most of the instruments are not going to work after. We do have a novel method we’ll use in attempt to survive the lunar night,” he says.

Previously, engineers in other countries have used radioisotope heaters, which are nuclear devices, to keep their robotic structures alive.

But, Mr Sharaf and the team say they were exploring another way.

The 27-year-old has a master’s degree in electrical and electronics engineering from the University of Bristol in the UK.

He became part of Lab 37 after joining the space centre in 2017. His focus is on the rover’s electrical power subsystems and motor control.

“The power system plays a vital role in keeping the rover alive,” Mr Sharaf says.

“A typical power system usually consists of three different sections – the first is generating power using solar panels, store it in a battery, which then gets distributed to the rest of the robot. So, it is like the heart of the rover.”

Youngest on the team

Amna Khalifa, a mechanical engineer and the youngest member of the team, describes being part of the mission as a “huge opportunity”.

The 25-year-old joined the space centre immediately after graduating from Khalifa University with a bachelor’s degree in mechanical engineering.

She looks after the mobility subsystem of the rover, as well as the gimbal – the arm on top of the rover that holds the camera.

Her job is to make sure the gimbal, wheels and other parts attached to the rover are working as they should. Each of those parts is essential to ensuring there are no mechanical faults during lunar exploration.

“I think the moment where I'll be holding my breath is when the rover will make its first movement after the lander deploys the ramp. It will then climb down to the surface. I’ll be very nervous, but probably excited too,” she says.

“At this young age, this is such a huge responsibility and it’s an opportunity that could be once in a lifetime.”

The data Rashid will gather

The mission aims to solve some of the Moon’s many mysteries, such as why lunar dust sticks to other surfaces, how it is formed and what it is made of.

It was during the Apollo missions when astronauts discovered that lunar dust, called regolith, stuck to their suits and boots.

The electrically charged particles can be dangerous to the health of astronauts and spacecraft, because they stick to almost everything.

Interest in lunar resources among space agencies has recently reached a high.

At present, Nasa is paying private companies to mine lunar soil and rocks and transfer full ownership to them.

ispace is one of the companies selected by the space agency to mine resources. The Hakuto-R lander will not bring back the samples, but will collect them, send back images and the location of the resources, before transferring ownership to Nasa. This means the resource will legally belong to the space agency.

It is not known if Nasa's mining efforts are motivated by scientific objectives but a statement from the agency speaks of potential commercial gain: "The Moon holds billions of dollars of untapped resources."

The Rashid rover will also study the thermal properties of the surface structure, the Moon's geology and lunar photoelectron sheath – a phenomenon created on the surface by the continuous bombardment of solar wind and cosmic rays.

Different materials attached on the rover’s wheels will help measure their strengths and weaknesses against lunar particles. This will help develop astronaut suits and other technology needed for future missions.

Other than science goals, the mission aims to advance Emirati space engineering and enable the UAE to be part of global space-exploration efforts.

Nasa, Russia and China aim to build a human base on the Moon or around its orbit. The US space agency wants to use this as a gateway for sending astronauts to Mars in the future.

Scientific findings made by the Rashid rover could also help other countries in their efforts, particularly in designing technologies and space suits.

The team hopes to receive more than a thousand images from the rover.

The UAE's future space plans

The Rashid rover is the first of many Moon exploration efforts the UAE intends to make.

During the Global Space Exploration Conference in Russia this year, an official with the space centre revealed the UAE's long-term plan.

“A lot of people asked the question why we skipped over the Moon when we launched the Hope probe to Mars. But we’ve kicked off our latest project, which is the Rashid rover that will explore the lunar surface,” said Salem Al Marri, the deputy director-general of the space centre.

“Our objective is to build and send a second rover by 2024 or 2025. There are plans of sending orbiters around the Moon and we do have an eye on human exploration of the Moon in partnership with different players.”

The plan also involves potentially talking to partners about the possibility of sending Emirati astronauts to the Moon.
