DUBAI — DMSat-1, the emirate’s first nanometric environmental satellite, developed by Dubai Municipality in collaboration with the Mohammed Bin Rashid Space Centre (MBRSC), has reached its orbit 550 km above Earth, following its successful launch from the Baikonur Cosmodrome in Kazakhstan aboard the Soyuz 2.1a space rocket.
The launch was supervised by a team of officials and engineers from MBRSC and Dubai Municipality.
The first signal from DMSat-1 was received at MBRSC’s mission control center at 4:42 p.m. on Monday, signaling that the satellite had reached its orbit and begun its scientific mission. Under the supervision of MBRSC, once the testing of onboard subsystems and instruments is completed and verified, the satellite will move into its operational phase, in which it will monitor, collect and analyze environmental data as well as to measure air pollutants and greenhouse gases.
The satellite was fully manufactured and developed by the Space Flight Laboratory (SFL) at the University of Toronto in Canada, and a team from MBRSC supervised the development and worked on the final testing of the satellite before being moved to the Baikonur Cosmodrome in Kazakhstan. The second team of engineers and experts from MBRSC joined the base team to complete the final functional testing and integration of the satellite with the launch vehicle. The DMSat-1 carries state-of-the-art environmental monitoring equipment.
The satellite was installed onboard the Soyuz 2.1a rocket on March 7 and completed pre-launch tests on March 12. The rocket carrying the satellite was then transported to the launch site on 17th March in preparation for the launch day.
After the successful launch, the DMSat-1 began the in-orbit testing, calibration, and validation phase to ensure all systems and instruments onboard are fully functional and ready for the next phase. During the second phase, set to commence in the coming days, the satellite will monitor, collect and analyze environmental data, measure air pollutants and greenhouse gases, develop maps of the concentration and distribution of greenhouse gases as well as study and monitor seasonal changes of these gases. The data provided by the satellite will be used to find solutions and develop long-term plans to confront the challenges of urban pollution and climate change and explore the future environmental reality in Dubai and the UAE.
DMSat-1 confirms the UAE’s commitment to the terms of the Paris Climate Agreement, which calls for the provision of information and data on greenhouse gas emissions, as well as building national capacities in the field of studying and analyzing the phenomenon of global warming. The launch of the satellite is part of the Dubai Clean Energy Strategy 2050 and UAE Energy Strategy 2050 and contributes to the implementation of the national system for managing greenhouse gas emissions within the UAE National Plan for Climate Change 2017-2050.
The DMSat-1 satellite launch project is an exceptional opportunity to build new research and technical capabilities in the fields of environmental scientific research at the local level. It will also contribute to opening new horizons for harnessing space technology to serve the environmental sectors and achieve sustainability.
Dawoud Al Hajri, the director of Dubai Municipality, said: “DMSat-1 is an embodiment of the will to excel that characterizes the UAE. Guided by the wisdom of our leadership, our national space program has been able to engage in qualitative areas and enhance its contributions to human civilization.”
Al Hajri also said those who managed the DMSat-1 satellite project are UAE nationals who have acquired high levels of knowledge and skills. He further emphasized that DMSat-1 will strengthen the UAE’s accumulated experience in the field of satellites, enhance its achievements in the fields of space and satellites, and support the UAE’s unlimited aspirations and its goal of becoming one of the major players in this field.
Hamad Obaid AlMansoori, the chairman of the MBRSC, said: “The DMSat-1 satellite constitutes a new impetus for the UAE to achieve its developmental strategies and make it the leading country in the world capable of using the latest global technologies to build sustainable cities. The satellite will contribute to providing accurate scientific information that helps decision-makers take necessary measures to improve the environment.”
Yousuf Hamad AlShaibani, director-general of the MBRSC, said: “The Mohammed Bin Rashid Space Centre is pleased to be part of any scientific space project that supports the nation’s institutions and helps build a better future in line with the vision of our leadership.”
Adnan AlRais, DMSAT-1 program manager & senior director of remote sensing Department at MBRSC, said: “The launch of the DMSat-1 satellite will bring about a fundamental shift in the field of obtaining environmental data in the country and the region, as it contains the latest technologies in the field of monitoring air pollutants and greenhouse gases.”
Alia Al-Harmoudi, director of the Environment Department, Dubai Municipality, said: “The information provided by the satellite will help us determine the measures needed to combat climate change and develop long-term environmental plans.”
Weighing 15 kilograms, the DMSat-1 satellite contains state-of-art scientific instruments to monitor air quality and detect greenhouse gases as well as fine particles in the atmosphere. Data will be stored on the onboard storage system and downloaded to MBRSC’s ground station. Over a period of three to five days, the satellite will monitor a single site more than once from seven different angles. It will orbit the earth 14 times a day and will pass over the MBRSC ground station four to five times a day to receive new imaging orders and enable downloading of data.
Hope Mars mission into new orbit; The transition from capture orbit has begun
Dubai — The Emirates Mars Mission (EMM), the first interplanetary exploration undertaken by an Arab nation, Tuesday announced it had commenced its transition from its capture orbit to its science orbit with the successful completion of a 510 second (8.36 minutes) burn of its thrusters.
Barring the requirement for a minor course correction, the spacecraft is now in its final orbit of Mars and ready for its two-year science data gathering phase — the core aim of the mission.
“Although the Hope Probe is a huge achievement and a source of great national pride, its core objective, defined right from day one of this mission, is to build the first complete picture of Mars’ atmospheric dynamics,” said Omran Sharaf, EMM Project Director.
“The Transition to Science Maneuver (TSM) was critically important and I can say was the last truly scary moment for the mission because there was a very real risk of losing the spacecraft during this last burn.
“We’re now assessing the results of that burn, but I can say we are confident that we will not need a further large correction maneuver.”
The transition saw the Hope Probe move from its 1,063 by 42,461 capture orbit to a 20,000 by 43,000 science orbit. The maneuver was the last scheduled ‘big burn’ in the spacecraft’s journey from its launch on the July 20, 2020.
The science phase will commence on April 14 with a number of calibration and test runs that aim to establish a sound baseline for the accurate and efficient management of the measurements from the spacecraft’s three instruments.
The mission’s two-year science data collection will formally commence on May 23, 2021, with data being made available globally in October.
“Once we have established our stable science orbit and deployed our instruments, we can start building datasets and testing our systems with the live data,” said Hessa Al Matroushi, EMM Science Lead.
“This is the data we will be processing, formatting and sharing with the world’s science and academic communities openly through our website.”
The painstaking process of science data gathering consists of making repeated ‘passes’ around Mars and mapping each set of measurements to build a dynamic picture of the movement of dust, ice and water vapor throughout the planet’s atmospheric layers.
As well as measuring hydrogen, oxygen, carbon monoxide and ozone, the probe will capture variations in temperature. The unique elliptical 25-degree orbit of the Hope probe enables a planet-wide, high-resolution sample to be taken each 225 hours (9.5 days).
“If you imagine spinning a basketball on your finger and then wrapping it with wool as it spins, you get an idea of how Hope covers the whole planet over consecutive orbits. While we’re doing that, we’re constantly measuring with two spectrometers and an imager.
“These three data streams combine to give us a holistic, powerful and unique picture of Mars’ atmosphere that we hope will answer many, many questions we have about the planet and our theories regarding its atmospheric loss,” said Al Matroushi.
The Hope probe carries three science instruments: EXI – The Emirates eXploration Imager is a 12 megapixel digital camera that captures high-resolution images of Mars along with measuring water ice and ozone in the lower atmosphere through the UV bands.
EMIRS – The Emirates Mars InfraRed Spectrometer collects information on surface and atmospheric temperatures and measures the global distribution of dust, ice cloud, and water vapor in the Martian lower atmosphere.
EMUS – The Emirates Mars Ultraviolet Spectrometer measures oxygen and carbon monoxide in the thermosphere and the variability of hydrogen and oxygen in the exosphere.
EMM and the Hope probe are the culmination of an international collaboration, knowledge transfer and development effort.
The spacecraft and its instruments were designed and developed by MBRSC engineers working with academic partners, including LASP at the University of Colorado, Boulder; Arizona State University and the University of California, Berkeley.
The Hope Probe’s historic journey to the Red Planet coincides with a year of celebrations to mark the UAE’s Golden Jubilee.
