The UAE’s Hope probe has moved to a new orbit around Mars to study one of the planet’s tiny moons.
Deimos, which measures only 6.2km in radius, is the smaller of the two moons that orbit the Red Planet.
Hope, the Arab world’s first interplanetary mission, will perform fly-bys that will take it within 100km of the moon.
The announcement was made on February 9, the second anniversary of the spacecraft reaching Mars.
“The Emirates Mars Mission has a unique opportunity to fully characterise the disc-resolved composition, thermophysics, shape and geologic surface features of Deimos in resolution that haven’t been acquired before,” said Hessa Al Matroushi, science lead of the mission.
Moving to the new orbit
Since arriving in Mars orbit, the Hope probe has been in an elliptical orbit between 22,000km and 44,000km from the planet’s surface, allowing it to observe from much higher above than any other spacecraft.
Now, the inclination of that orbit has changed after the spacecraft performed a manoeuvre called the Lambert orbital transfer.
This means the spacecraft fired its Delta-V thrusters to make manoeuvres that allowed it to move from one elliptical orbit to another.
Two of the three required manoeuvres have already been made, allowing it to reach a new orbit between 20,000km and 43,000km with a 25-degree incline towards the planet.
“Previously, we didn't have any reason to move the orbit,” Ms Al Matroushi said.
“But now we’re exploring a new adventure and science mission.”
What will it study?
Engineers are using the probe’s three main science instruments to capture images and data of the moon.
These include an exploration imager ― a high-resolution camera ― to photograph the moon, and the infrared and ultraviolet spectrometers to measure its temperature and observe its thermophysical properties, including its regolith, or dust.
The first Deimos fly-by took place in late January, and as the probe moves to its closest approach to the moon, it will take high-resolution images.
It will also continue to study atmospheric conditions on Mars. So far, the Emirates Mars Mission team have released six batches of data on the Red Planet, more than 1.7 terabytes.
What's special about Deimos?
Deimos completes an orbit around Mars every 30 hours and is much smaller than its companion, Phobos.
"Like Phobos, Deimos is a small and lumpy, heavily cratered object," Nasa said.
"Its craters are generally smaller than 1.6 miles [2.5km] in diameter, however, and it lacks the grooves and ridges seen on Phobos.
"Deimos also has a thick regolith, perhaps as deep as 328 feet [100m], formed as meteorites pulverised the surface."
The moon has been studied by spacecraft from other space agencies, but Emirati engineers are hoping that their probe will bring new discoveries, including new data on the moon's dark side ― the part that faces the planet.

Yemen's Bahais and the charges they often face
The Baha'i faith was made known in Yemen in the 19th century, first introduced by an Iranian man named Ali Muhammad Al Shirazi, considered the Herald of the Baha'i faith in 1844.
The Baha'i faith has had a growing number of followers in recent years despite persecution in Yemen and Iran.
Today, some 2,000 Baha'is reside in Yemen, according to Insaf.
"The 24 defendants represented by the House of Justice, which has intelligence outfits from the uS and the UK working to carry out an espionage scheme in Yemen under the guise of religion.. aimed to impant and found the Bahai sect on Yemeni soil by bringing foreign Bahais from abroad and homing them in Yemen," the charge sheet said.
Baha'Ullah, the founder of the Bahai faith, was exiled by the Ottoman Empire in 1868 from Iran to what is now Israel. Now, the Bahai faith's highest governing body, known as the Universal House of Justice, is based in the Israeli city of Haifa, which the Bahais turn towards during prayer.
The Houthis cite this as collective "evidence" of Bahai "links" to Israel - which the Houthis consider their enemy.

What is graphene?
Graphene is extracted from graphite and is made up of pure carbon.
It is 200 times more resistant than steel and five times lighter than aluminum.
It conducts electricity better than any other material at room temperature.
It is thought that graphene could boost the useful life of batteries by 10 per cent.
Graphene can also detect cancer cells in the early stages of the disease.
The material was first discovered when Andre Geim and Konstantin Novoselov were 'playing' with graphite at the University of Manchester in 2004.
Ziina users can donate to relief efforts in Beirut
Ziina users will be able to use the app to help relief efforts in Beirut, which has been left reeling after an August blast caused an estimated $15 billion in damage and left thousands homeless. Ziina has partnered with the United Nations High Commissioner for Refugees to raise money for the Lebanese capital, co-founder Faisal Toukan says. “As of October 1, the UNHCR has the first certified badge on Ziina and is automatically part of user's top friends' list during this campaign. Users can now donate any amount to the Beirut relief with two clicks. The money raised will go towards rebuilding houses for the families that were impacted by the explosion.”

What vitamins do we know are beneficial for living in the UAE
Vitamin D: Highly relevant in the UAE due to limited sun exposure; supports bone health, immunity and mood.
Vitamin B12: Important for nerve health and energy production, especially for vegetarians, vegans and individuals with absorption issues.
Iron: Useful only when deficiency or anaemia is confirmed; helps reduce fatigue and support immunity.
Omega-3 (EPA/DHA): Supports heart health and reduces inflammation, especially for those who consume little fish.
What are NFTs?
Are non-fungible tokens a currency, asset, or a licensing instrument? Arnab Das, global market strategist EMEA at Invesco, says they are mix of all of three.
You can buy, hold and use NFTs just like US dollars and Bitcoins. “They can appreciate in value and even produce cash flows.”
However, while money is fungible, NFTs are not. “One Bitcoin, dollar, euro or dirham is largely indistinguishable from the next. Nothing ties a dollar bill to a particular owner, for example. Nor does it tie you to to any goods, services or assets you bought with that currency. In contrast, NFTs confer specific ownership,” Mr Das says.
This makes NFTs closer to a piece of intellectual property such as a work of art or licence, as you can claim royalties or profit by exchanging it at a higher value later, Mr Das says. “They could provide a sustainable income stream.”
This income will depend on future demand and use, which makes NFTs difficult to value. “However, there is a credible use case for many forms of intellectual property, notably art, songs, videos,” Mr Das says.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.
