The UAE’s first interplanetary mission
The United Arab Emirates’ Hope mission, scheduled to launch to the Red Planet July 16, 2020 will conduct a detailed examination of the Martian atmosphere.
Also known as the Emirates Mars Mission, Hope is an orbiter designed to spend one Martian year (two Earth years) looking at the Red Planet’s atmosphere, studying how it eroded over time until Mars no longer was able to host liquid water on the surface.

Mars ‘Hope’: UAE’s 1st interplanetary probe will make history
The boldest Mars missions of all time

Going to Mars was meant to spur the nation’s technology industry to great heights, and also to create a planetary science community in a region where there was practically none before the mission.
This is the first time any Arab nation has attempted a Red Planet mission, and the development happened quickly as UAE leaders first considered a Mars orbiter in 2014.

Looking at the spacecraft bus
The UAE has decided to ramp up its own spacecraft-building technologies — such as building Hope’s “bus,” or main structural component seen in this picture — to diversify the nation’s industries.
The nation is largely built on oil revenue and is looking to create other streams of income on top of this one, and it hopes that the Mars mission would help spur technological development in other sectors, such as electronics.

The team brought on international partners to help get the spacecraft ready efficiently, including the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics.
The partnership benefitted from the university’s expertise on the Mars Atmosphere and Volatile Evolution (MAVEN) mission, which is also studying the Martian atmosphere with different science questions.

Hope is ready!
Some spacecraft engineers pose before the Hope orbiter on Feb. 18, 2020. The UAE built the spacecraft domestically, while asking for international expertise to meet their goal of performing new science at Mars with their very first mission.
Personnel quickly embedded themselves in the international community of Mars scientists to get up to speed on the latest science and to pick what aspects of the planet were best worth studying.

Hope will ride a Japanese H-2A rocket to orbit, lifting off from the Tanegashima Space Center in Japan.
This booster has already sent aloft at least one interplanetary mission — Japan’s Akatsuki spacecraft, which studied the planet Venus. Other prominent missions launched on this rocket type include Selene (aka Kaguya) that studied the moon, the Ikaros solar-sailing spacecraft, and the Hayabusa 2 mission that plans to return a sample from the asteroid Ryugu in late 2020.

Cruising to Mars
This artist’s illustration shows the Hope orbiter making its way into space on top of the H-2A rocket. It will spend between seven and nine months traveling to Mars before arriving in orbit in May 2021 — just in time for the 50th anniversary of the founding of the United Arab Emirates.
The satellite has a total mass, with fuel, of 3,300 lbs. (1,500 kilograms), according to NASA, and is about the size and weight of a small car.
The spacecraft is expected to last for at least two Earth years in Mars’ orbit, but its mission can be extended to 2025 if the spacecraft remains in good health and funding is available for the mission extension.

Complicated maneuvers in space
This illustration shows in detail all the mission steps required to get Hope into orbit around Mars.
Shortly after launch, it will unfold its solar panels to recharge its batteries for the trip to Mars. As Hope approaches the Red Planet, it will use its star trackers to navigate and to enter the correct orbit.
The final orbit will be a 55-hour-long, slightly elliptical path around Mars that measures roughly 12,500 by 26,700 miles (20,000 by 43,000 kilometers). At its widest, the orbit of Hope is 10 times the diameter of Mars.

There are three main instruments on the Hope orbiter:
The Emirates Mars Infrared Spectrometer (EMIRS) looks at the Martian atmosphere’s dust, ice clouds, water vapor and temperature profile.
The Emirates Exploration Imager (EXI) will image the Martian atmosphere to look for dust, water ice and ozone abundance.
The Emirates Mars Ultraviolet Spectrometer (EMUS) is a spectrometer that will examine changes in the atmosphere and emissions of hydrogen, oxygen and carbon monoxide, among other things.

In collaboration with Arizona State University, the Mohammed bin Rashid Space Centre in Dubai designed EMIRS to measure the dust, ice clouds, water vapor and temperature profile of the Martian atmosphere. These observations will add on to other missions’ work at the Red Planet and lead to a greater understanding of planetary atmospheres more generally.
