The Emirates Mars Mission, the first interplanetary exploration undertaken by an Arab nation, is expected to lift off in July (exact launch date depends on weather conditions) on an H-IIA rocket from Tanegashima, Japan, and arrive at Mars in February 2021, where it will spend two years orbiting the red planet gathering crucial science data.
The mission is being carried out by the Mohammed bin Rashid Space Centre (MBRSC) in the United Arab Emirates (UAE) in collaboration with a number of research institutions, including Arizona State University (ASU).
The orbiter, named 'Hope' (Al Amal in Arabic), carries three science instruments including the Emirates Mars Infrared Spectrometer (EMIRS), an interferometric thermal infrared spectrometer developed by Philip Christensen of ASU's School of Earth and Space Exploration with Christopher Edwards of Northern Arizona University's (NAU) Department of Astronomy and Planetary Science, in a partnership with the MBRSC.
EMIRS will provide a unique view of the lower and middle atmosphere of the planet, measuring the distribution of dust particles and ice clouds while tracking the movement of water vapor and heat through the atmosphere.
The scientific goal of the mission is to provide an unprecedented global view of the Martian atmosphere. Such a perspective is necessary to understand the connections within and between the upper and lower atmospheres and how those connections help to drive atmospheric escape. This escape has helped to shape Mars' evolution from a warm, episodically wet world in the ancient past to the cold, dry planet we see today. Unique to Hope is its orbit, which enables near-complete daily and geographic coverage, providing a weather-satellite style view of all layers of the Martian atmosphere from the surface on up to space.
This mission will give scientists greater insight into how our own planet may have evolved, as well as enable greatly improved weather forecasting to help support the future human missions to Mars. Importantly, Hope addresses several key goals of the Mars Exploration Program Analysis Group (representing the consensus of the international Mars community) in regard to both science and human exploration.
"It has been a wonderful experience to work with the UAE team on this unique international partnership," says ASU Regents Professor and planetary scientist Christensen. "Only a very small number of nations have sent missions to Mars, and it is a real honor for ASU to have been invited to participate in this exciting adventure."
In addition to EMIRS, the orbiter includes a multi-band camera called the Emirates eXploration Imager (EXI) and a far-ultraviolet imaging spectrograph called the Emirates Mars Ultraviolet Spectrometer (EMUS). The EXI camera is capable of taking high resolution images and will measure properties of water, ice, dust, aerosols and ozone in Mars' atmosphere. The EMUS spectrometer will measure global characteristics and variability in the thermosphere and hydrogen and oxygen coronae. Both were developed at the Laboratory for Atmospheric and Space Physics (LASP) at University of Colorado, Boulder.
The spacecraft, which is about the size of a small car, was constructed at LASP by a joint MBRSC/LASP team led by Project Director Omran Sharaf from MBRSC and deputy program manager and science lead investigator Her Excellency Sarah Al Amiri. The overall team working on the Mission comprises some 200 staff from MBRSC, 150 from LASP and 100 from other partners, as well as an international science team.
"Collaboration and knowledge transfer have been key to the development of the Emirates Mars Mission," said Sharaf. "Our partners at ASU and NAU have been key to ensuring the success of the mission, delivering an extraordinary instrument in almost half the time of conventional missions but also in providing the resources and knowledge we need to drive our own development of space systems engineering and planetary science."
The mission's name, Hope, was chosen to send a message of optimism to millions of young Arabs, according to Sheikh Mohammed bin Rashid Al Maktoum, the Ruler of the Emirate of Dubai for whom MBRSC is named. The resulting mission data aims to make major advances in our understanding of the Martian climate system and will be shared freely online with more than 200 institutions worldwide.
"The science enabled by the Emirates Mars Mission will be second to none, but the goals of the mission don't stop there," says Edwards, who is the instrument scientist for EMIRS. "The collaboration developed through this project has helped train the next generation of engineers and scientists in the UAE through professional and student opportunities. It's been an amazing experience and has cultivated life-long colleagues and friendships that will endure beyond the Hope mission to Mars."
