Science results from Emirates Mars Mission trigger new discoveries

DUBAI, 14th December, 2021 (WAM) — The Emirates Mars Mission, the first interplanetary exploration undertaken by an Arab nation, has triggered a rush of new observations, discoveries and insights into Mars’ unique atmosphere, its composition and dynamics.

With key announcements already made including new and startling observations of Mars’ discrete aurora and unprecedented views of dayside oxygen and carbon monoxide structures in the planet’s atmosphere, new avenues of exploration are now being opened up by the slew of data being brought back from the Hope spacecraft. For the first time, Hope is building a full diurnal picture of Mars’ atmosphere.

"The success of Hope is already assured from our early results and observations and we can already see a vast number of new potential avenues of exploration opening up as a result of our early data," said Emirates Mars Mission Science Lead, Hessa Al Matroushi. "We are seeing Mars in remarkable detail and are able to characterise the diurnal behaviours of Mars’ atmosphere for the first time ever. The potential we are now seeing from the mission undoubtedly exceeds our expectations."

Papers and posters being shared and presented at the AGU21 Fall Meeting in New Orleans reflect the unique picture of Mars’ atmosphere being built by EMM’s Hope Probe, with a combination of Hope’s advanced instrumentation and smart elliptical orbit providing new views of the Martian atmosphere at all times through the day, night and seasons of the Red Planet.

Christopher S. Edwards, EMIRS Instrument Lead, said, "The ability of EMM to observe Mars at all local times on short timescales enables the daily variation of these clouds to be studied. The EMIRS observations show that clouds are thickest and cover the most area early in the morning and late in evening with fewer clouds near midday. The comparison of clouds observed by EMIRS at thermal-infrared wavelengths to those observed by EXI at visible wavelengths can provide further information about the clouds, such as size of the water ice aerosols that make up the clouds."

"As on the earth, clouds on Mars are an important part of the water cycle and characterising how they change from hour-to-hour and day-to-day is an important part in understanding both the present and past climates," said Michael Wolff, EXI Instrument Lead.

Filling a crucial gap in our understanding of Mars and meeting its mission objective of addressing a number of science goals defined by MEPAG (the Mars Exploration Program Analysis Group), Hope’s ground-breaking observations are available to scientists and enthusiasts globally, uploaded to the EMM Science Data Centre and available freely from the emm.ae website.

Hope set out to measure the global, diurnal and seasonal response of the Martian atmosphere to solar forcing; the atmospheric conditions relating to the rate of atmospheric escape – particularly of Hydrogen and Oxygen and the temporal and spatial behaviour of Mars’ exosphere. With early results showing exciting observations of Mars’ discrete aurora and additional bandwidth and resources available to encompass additional observations, further measurements of auroral phenomena have been brought into the mission’s goals, extending its capabilities beyond Hope’s planned goals.

Mars Hope carries three instruments; the Emirates eXploration Imager (EXI) digital camera, which captures images of Mars with a resolution of 2 to 4 km along with measuring the amount of water ice and ozone in the lower atmosphere through the UV bands; the Emirates Mars InfraRed Spectrometer (EMIRS), which measures the emitted energy from the martian surface and atmosphere, deriving the global distribution of dust, ice cloud, and water vapor in the Martian lower atmosphere, and the Emirates Mars Ultraviolet Spectrometer (EMUS), which measures oxygen and carbon monoxide in the thermosphere and the variability of hydrogen and oxygen in the exosphere.

"By comparing the images of hydrogen that we gain from the EMUS instrument to the maps of water ice, water vapor, and dust acquired by the EXI and EMIRS instruments, scientists will be able to reconstruct the details of how hydrogen is transported through the Martian atmosphere and how water has been lost from the planet over the history of the Solar System," Said EMM Deputy Science Lead and EMUS Instrument Lead Justin Deighan. "Thanks to the uniquely large orbit of the Hope probe around Mars, the instruments on the Hope probe are able to view the planet from different points of view across all times of day, bringing powerful new insights to our understanding of Mars’ atmospheric dynamics."

The Mission’s Hope Probe is following its planned 20,000 – 43,000 km elliptical science orbit, with an inclination to Mars of 25 degrees, giving it a unique ability to complete one orbit of the planet every 55 hours and capture a full planetary data sample every nine days throughout its one Martian year (two Earth year) mission to map Mar’s atmospheric dynamics.

EMM and the Hope probe are the culmination of a knowledge transfer and development effort started in 2006, which has seen Emirati engineers working with partners around the world to develop the UAE’s spacecraft design, engineering and manufacturing capabilities. Hope is a fully autonomous spacecraft, carrying three instruments to measure Mars’ atmosphere. Weighing some 1,350 kg, and approximately the size of a small SUV, the spacecraft was designed and developed by MBRSC engineers working with academic partners, including LASP at the University of Colorado, Boulder; Arizona State University, the University of California, Berkeley, Space Science Institute, Boulder and Northern Arizona University.

The Hope Probe’s historic journey to the Red Planet coincided with a year of celebrations to mark the UAE’s Golden Jubilee.

Dubai Police warns Against Using Police Emergency Strobe Lights

The Dubai Traffic Police has recently warned motorists against using police and emergency vehicle warning lights, after two vehicles were spotted on the road taking advantage of the exclusive entitlement of the police to be given way in case of emergency.

Colonel Juma bin Suwaidan, Acting Director of the General Traffic Department, urged road users to adhere to traffic laws to avoid facing legal liabilities and prevent endangering their lives and others.

Col bin Suwaidan stated further that the police patrols had impounded two vehicles on two separate occasions for illegally fitting their vehicles with using emergency warning lights similar to the police, giving other motorists a false impression of authority to give way.

“We have spotted one at the Emirates Road and the other at Sheikh Mohammed Bin Zayed Road. Reports were filed against the two, and their vehicles were confiscated and fined,” he added.

Her Highness Sheikha Dr. Shamma bint Mohammed bin Khalid Al Nahyan announces the launch of the “Emirati Miniatures initiative” from the Courtauld Gallery in London.

“Art is the mirror of history and a true reflection of the extent of the civilised development of society.”

I feel a special state of spiritual and intellectual transcendence. ” Her Highness Sheikha Dr. Shamma expressed her conviction in the value of the arts and their being a title for advanced people and civilizations. This statement came during Her Highness’ visit to the Gallery in the British capital, London, at the beginning of her meetings and her visit as part of Her Highness’s cultural and knowledge programme for knowledge and human communication.

The Courtauld Gallery is interested in the history of the arts through different ages and human civilizations, and many of the senior art historians in the British scientific community belong to it. The Museum: Edouard Manet, Vanessa Bell, and Lucas Cranach (Painting of Adam and Eve), as well as the French artist Pierre Auguste Renoir, the Dutch artist Van Gogh, and many other artists.

Her Highness and the accompanying delegation were welcomed by Professor Deborah Salo, Director of the College; Dr. Karen Sears; Mrs. Francesca Hoyt and Mrs. Camilla Knight, where Her Highness and the accompanying delegation accompanied Professor Debrois on a tour between the various pavilions of the museum and the exhibition.

Her Highness held a meeting with the director of the gallery and the work team, where she thanked and appreciated them for their good reception.
