Five fascinating facts about the UAE’s Hope Probe Mars Mission

Wednesday, February 9 2022 marks one year since the UAE became just the fifth country in the world to reach Mars.

Missions to the Red Planet have a success rate of only 50 per cent, but a year ago today the UAE wrote its name into the record books when the Hope probe spacecraft successfully entered the Martian orbit.

And over the past year the probe has been beaming back images from the Red Planet, revealing a series of stunning landscapes.

Scientists from the University of Colorado Boulder’s Laboratory for Atmospheric Space Physics worked with the Emirati team to help make the mission a reality. They explained some of the key stages of Hope’s journey. Here are five fascinating facts about the mission.

1. The probe is loaded with highly explosive fuel

Where there are rockets, there are massive amounts of explosive liquids. And the Hope probe is no different.

It was loaded with 800 kilograms of hydrazine, a fuel propellant commonly used in spacecraft, for its journey to space.

According to the Royal Chemistry Society, when hydrazine is mixed with oxidising agents, it creates a mixture so explosive that ignition is not needed. Hydrazine decomposes as fuel burns, forming gases that are released from the spacecraft to create thrust.

Hope used half its fuel reserves during the orbit insertion phase on February 9, 2021.

First, engineers rotated the spacecraft so the thrusters pointed in the right direction. Then, Hope’s six thrusters fired to help slow it down from 120,000 kilometres per hour to 18,000kph.

The thrusters were active for 28 minutes – the longest period during this mission – to help adjust Hope’s velocity so it could be captured by Mars’ gravity.

2. Contact was lost with the probe for almost half an hour

Long-distance relationships are difficult, but having no contact at all is worse.

There is a communication delay between mission control and the spacecraft. This is because of the enormous distance between Earth and Mars.

When Hope entered the Mars orbit, it hid behind the planet for 15-20 minutes (called the occultation period), causing all radio signals to be lost - meaning the team did not know they were successful until contact was reestablished.

The occultation stage was a tense period in the mission control room.

3. Hope orbits Mars like a Moon

What sets the UAE’s mission to Mars apart from any other is the special orbit Hope is placed in.

It is at an elliptical orbit between 22,000km and 44,000km from the planet’s surface – the farthest for a spacecraft to date.

Earth’s Moon orbits the planet near to the equator, similarly, Hope’s orbit will be almost parallel with Mars' equator.

The Moon-like orbit helps Hope visit the planet at every time of day.

Previous missions were carried out in highly inclined orbits that were very polar. This limited spacecraft to observing the planet at the same time of day each time.

Hope observes weather patterns and atmospheric conditions at different times of day and night.

Now in orbit, Hope makes a full circle of Mars every 55 hours, far longer than existing spacecraft.

The Mars Reconnaissance Orbiter currently takes 112 minutes to complete the loop, while Trace Gas Orbiter takes 120 minutes and the Maven takes four and a half hours. This is because each are far closer to the surface of the Red Planet.

4. Hope teamed up with another spacecraft while in deep space

In November 2020, Hope and the European Space Agency’s BepiColombo spacecraft each measured distribution of hydrogen in space together.

The European spacecraft was en route to Mercury, and both BepiColombo and Hope's instruments were facing each other so scientists took the opportunity to measure the amount of hydrogen between them.

Scientists from ESA and Mohammed bin Rashid Space Centre worked together to cross calibrate the instruments and get some extra science out of the mission.

Hope was also able to measure interplanetary dust, which is spread throughout space, some particles of which could predate our solar system.

In 2018, researchers in Hawaii found leftover dust from the birth of our solar system preserved in comets.

Studying these tiny particles could help them to learn more about how our planets and Sun formed.

5. Hope's gadgets include camera filters and ‘heat vision goggles’

Hope has three instruments it will use to perform its scientific tasks – an infrared spectrometer, exploration imager and ultraviolet spectrometer.

The exploration imager will take photos of the planet. It will use specific filters to restrict wavelengths of light and capture images that can help scientists learn about things such as ice in the atmosphere, small water ice particles, ozone and dust storms.

The infrared spectrometer will build images of the planet at different infrared wavelengths, almost like fancy heat vision goggles for Mars.

Each pixel could contain key information about the atmosphere, including temperature, water vapour, carbon dioxide, dust and water ice and temperature of the surface of the planet.

The ultraviolet spectrometer will help to make ultraviolet observations of the top of the atmosphere, helping measure particles that may escape from the planet.

Dirham Stretcher tips for having a baby in the UAE

Selma Abdelhamid, the group's moderator, offers her guide to guide the cost of having a young family:

• Buy second hand stuff

 They grow so fast. Don't get a second hand car seat though, unless you 100 per cent know it's not expired and hasn't been in an accident.

• Get a health card and vaccinate your child for free at government health centres

 Ms Ma says she discovered this after spending thousands on vaccinations at private clinics.

• Join mum and baby coffee mornings provided by clinics, babysitting companies or nurseries.

Before joining baby classes ask for a free trial session. This way you will know if it's for you or not. You'll be surprised how great some classes are and how bad others are.

• Once baby is ready for solids, cook at home

Take the food with you in reusable pouches or jars. You'll save a fortune and you'll know exactly what you're feeding your child.

Day 1, Abu Dhabi Test: At a glance

Moment of the day Dimuth Karunaratne had batted with plenty of pluck, and no little skill, in getting to within seven runs of a first-day century. Then, while he ran what he thought was a comfortable single to mid-on, his batting partner Dinesh Chandimal opted to stay at home. The opener was run out by the length of the pitch.

Stat of the day – 1 One six was hit on Day 1. The boundary was only breached 18 times in total over the course of the 90 overs. When it did arrive, the lone six was a thing of beauty, as Niroshan Dickwella effortlessly clipped Mohammed Amir over the square-leg boundary.

The verdict Three wickets down at lunch, on a featherbed wicket having won the toss, and Sri Lanka’s fragile confidence must have been waning. Then Karunaratne and Chandimal's alliance of precisely 100 gave them a foothold in the match. Dickwella’s free-spirited strokeplay meant the Sri Lankans were handily placed at 227-4 at the close.

Three trading apps to try

Sharad Nair recommends three investment apps for UAE residents:

  • For beginners or people who want to start investing with limited capital, Mr Nair suggests eToro. “The low fees and low minimum balance requirements make the platform more accessible,” he says. “The user interface is straightforward to understand and operate, while its social element may help ease beginners into the idea of investing money by looking to a virtual community.”
  • If you’re an experienced investor, and have $10,000 or more to invest, consider Saxo Bank. “Saxo Bank offers a more comprehensive trading platform with advanced features and insight for more experienced users. It offers a more personalised approach to opening and operating an account on their platform,” he says.
  • Finally, StashAway could work for those who want a hands-off approach to their investing. “It removes one of the biggest challenges for novice traders: picking the securities in their portfolio,” Mr Nair says. “A goal-based approach or view towards investing can help motivate residents who may usually shy away from investment platforms.”

Who was Alfred Nobel?

The Nobel Prize was created by wealthy Swedish chemist and entrepreneur Alfred Nobel.

  • In his will he dictated that the bulk of his estate should be used to fund "prizes to those who, during the preceding year, have conferred the greatest benefit to humankind".
  • Nobel is best known as the inventor of dynamite, but also wrote poetry and drama and could speak Russian, French, English and German by the age of 17. The five original prize categories reflect the interests closest to his heart.
  • Nobel died in 1896 but it took until 1901, following a legal battle over his will, before the first prizes were awarded.

Chef Nobu's advice for eating sushi

“One mistake people always make is adding extra wasabi. There is no need for this, because it should already be there between the rice and the fish.
“When eating nigiri, you must dip the fish – not the rice – in soy sauce, otherwise the rice will collapse. Also, don’t use too much soy sauce or it will make you thirsty. For sushi rolls, dip a little of the rice-covered roll lightly in soy sauce and eat in one bite.
“Chopsticks are acceptable, but really, I recommend using your fingers for sushi. Do use chopsticks for sashimi, though.
“The ginger should be eaten separately as a palette cleanser and used to clear the mouth when switching between different pieces of fish.”
