Researchers at New York University Abu Dhabi have used the Hope probe’s data to measure the surface temperature of Mars more extensively.
The new study measured the surface temperature of the entire planet, including its daily and seasonal variations.
Nasa orbiters and rovers have made such measurements before, but Hope’s unique placement in Mars' orbit – which is much higher up than others – allows it to see various parts of the planet during different times of the day.
The findings were published in the Monthly Reviews of the Royal Astronomy Society, a peer-reviewed scientific journal, on August 12.
Hope is the first Arab spacecraft to journey to Mars.
Built by Emirati engineers, along with three US universities, it has been orbiting the planet since February 9, 2021.
Dimitra Atri, research scientist at the NYUAD's Centre for Space Science and the lead author of the study, told The National that they used Hope’s infrared spectrometer instrument, also called EMIRS, to make the measurements.
“We, for the first time, measured the surface temperature of the entire planet, and its daily and seasonal variations, using data from the UAE's Hope probe,” he said.
“Due to Hope's unique orbit, we, for the first time were able to measure the temperature at all local times for most of the planet.
“This was not possible earlier because other orbiters are at a highly elliptical orbit and unlike Hope, they only measure a very small fraction of the planet at once.
“While doing the analysis, we were pleasantly surprised by the quality of data, so much so that we were able choose any point on the planet and get the daily and seasonal variation of temperature.”
The researchers found that the average surface temperature of Mars ranges between 140 Kelvin to 280 Kelvin, or -133°C to 7°C.
The observations by Hope were compared with data from Nasa’s Curiosity and Perseverance rovers, which are deployed on the Red Planet’s surface.
“Since I already work with both of these rovers, I knew that Curiosity's REMS instrument and Perseverance's MEDA instrument also continuously measure the surface temperature of Mars at Gale crater and Jezero crater, respectively,” Dr Atri said.
“So, I decided to compare the temperature we measured from the orbit with measurements from the surface.
“Overall, we found an excellent agreement among the three missions.”
Colder nights on Red Planet
However, Hope’s data showed that Mars could be colder at night than previously thought.
Dr Atri and his team are currently doing more research to determine whether these specific findings were accurate, or if there were factors that interfered with the measurements.
“There are some minor discrepancies, which we are trying to resolve and will lead to better estimation of global temperature data from Hope,” he said.
Mars has a very thin atmosphere and cannot retain heat. For decades, scientists have been trying to understand how the planet lost its atmosphere, making it impossible for it to host life.
Four sets of data captured by the Hope probe, totalling 118.5 gigabytes, have been released to the public since it arrived on Mars.
The observations have also helped Dr Atri create an atlas of the Red Planet, which aims to show how Mars changes over time.
The Atlas was released in English and in Arabic.
In December, the orbiter tracked a massive dust storm on Mars for more than two weeks, helping to show how quickly they can spread across the planet.
The rapidly evolving regional dust storm in late December had expanded to a size of several thousand kilometres.
Dust storms on Mars cause extremely turbulent weather. They can be up to 30 kilometres high and cover the entire planet.
The storms can be seen from space, making the planet appear as a bright ball of red.
Scientists hope that by studying them they can gain further insight into how they are drying out the planet by helping Martian water escape the planet's atmosphere.
Hope used a high-resolution camera and an infrared spectrometer to document the storm’s growth and dissipation.
The instruments revealed the thermal conditions of the planet’s surface and lower atmosphere, giving details about the geographic distribution of dust, water vapour, water and carbon dioxide ice clouds.

Who has lived at The Bishops Avenue?
- George Sainsbury of the supermarket dynasty, sugar magnate William Park Lyle and actress Dame Gracie Fields were residents in the 1930s when the street was only known as ‘Millionaires’ Row’.
- Then came the international super rich, including the last king of Greece, Constantine II, the Sultan of Brunei and Indian steel magnate Lakshmi Mittal who was at one point ranked the third richest person in the world.
- Turkish tycoon Halis Torprak sold his mansion for £50m in 2008 after spending just two days there. The House of Saud sold 10 properties on the road in 2013 for almost £80m.
- Other residents have included Iraqi businessman Nemir Kirdar, singer Ariana Grande, holiday camp impresario Sir Billy Butlin, businessman Asil Nadir, Paul McCartney’s former wife Heather Mills.
Hunting park to luxury living
- Land was originally the Bishop of London's hunting park, hence the name
- The road was laid out in the mid 19th Century, meandering through woodland and farmland
- Its earliest houses at the turn of the 20th Century were substantial detached properties with extensive grounds
5 of the most-popular Airbnb locations in Dubai
Bobby Grudziecki, chief operating officer of Frank Porter, identifies the five most popular areas in Dubai for those looking to make the most out of their properties and the rates owners can secure:
• Dubai Marina
The Marina and Jumeirah Beach Residence are popular locations, says Mr Grudziecki, due to their closeness to the beach, restaurants and hotels.
Frank Porter’s average Airbnb rent:
One bedroom: Dh482 to Dh739
Two bedroom: Dh627 to Dh960
Three bedroom: Dh721 to Dh1,104
• Downtown
Within walking distance of the Dubai Mall, Burj Khalifa and the famous fountains, this location combines business and leisure. “Sure it’s for tourists,” says Mr Grudziecki. “Though Downtown [still caters to business people] because it’s close to Dubai International Financial Centre."
Frank Porter’s average Airbnb rent:
One bedroom: Dh497 to Dh772
Two bedroom: Dh646 to Dh1,003
Three bedroom: Dh743 to Dh1,154
• City Walk
The rising star of the Dubai property market, this area is lined with pristine sidewalks, boutiques and cafes and close to the new entertainment venue Coca Cola Arena. “Downtown and Marina are pretty much the same prices,” Mr Grudziecki says, “but City Walk is higher.”
Frank Porter’s average Airbnb rent:
One bedroom: Dh524 to Dh809
Two bedroom: Dh682 to Dh1,052
Three bedroom: Dh784 to Dh1,210
• Jumeirah Lake Towers
Dubai Marina’s little brother JLT resides on the other side of Sheikh Zayed road but is still close enough to beachside outlets and attractions. The big selling point for Airbnb renters, however, is that “it’s cheaper than Dubai Marina”, Mr Grudziecki says.
Frank Porter’s average Airbnb rent:
One bedroom: Dh422 to Dh629
Two bedroom: Dh549 to Dh818
Three bedroom: Dh631 to Dh941
• Palm Jumeirah
Palm Jumeirah's proximity to luxury resorts is attractive, especially for big families, says Mr Grudziecki, as Airbnb renters can secure competitive rates on one of the world’s most famous tourist destinations.
Frank Porter’s average Airbnb rent:
One bedroom: Dh503 to Dh770
Two bedroom: Dh654 to Dh1,002
Three bedroom: Dh752 to Dh1,152

Teachers' pay - what you need to know
Pay varies significantly depending on the school, its rating and the curriculum. Here's a rough guide as of January 2021:
- top end schools tend to pay Dh16,000-17,000 a month - plus a monthly housing allowance of up to Dh6,000. These tend to be British curriculum schools rated 'outstanding' or 'very good', followed by American schools
- average salary across curriculums and skill levels is about Dh10,000, recruiters say
- it is becoming more common for schools to provide accommodation, sometimes in an apartment block with other teachers, rather than hand teachers a cash housing allowance
- some strong performing schools have cut back on salaries since the pandemic began, sometimes offering Dh16,000 including the housing allowance, which reflects the slump in rental costs, and sheer demand for jobs
- maths and science teachers are most in demand and some schools will pay up to Dh3,000 more than other teachers in recognition of their technical skills
- at the other end of the market, teachers in some Indian schools, where fees are lower and competition among applicants is intense, can be paid as low as Dh3,000 per month
- in Indian schools, it has also become common for teachers to share residential accommodation, living in a block with colleagues

Some of Darwish's last words
"They see their tomorrows slipping out of their reach. And though it seems to them that everything outside this reality is heaven, yet they do not want to go to that heaven. They stay, because they are afflicted with hope." - Mahmoud Darwish, to attendees of the Palestine Festival of Literature, 2008
His life in brief: Born in a village near Galilee, he lived in exile for most of his life and started writing poetry after high school. He was arrested several times by Israel for what were deemed to be inciteful poems. Most of his work focused on the love and yearning for his homeland, and he was regarded the Palestinian poet of resistance. Over the course of his life, he published more than 30 poetry collections and books of prose, with his work translated into more than 20 languages. Many of his poems were set to music by Arab composers, most significantly Marcel Khalife. Darwish died on August 9, 2008 after undergoing heart surgery in the United States. He was later buried in Ramallah where a shrine was erected in his honour.
