The United Arab Emirates’ Hope probe has successfully entered the red planet’s orbit, marking an historic day for missions to Earth’s neighbour.

The achievement makes the UAE only the fifth country in history to reach Mars.

Seven months ago the Hope launched from Earth, with the mission to gather data on the planet’s climate.

But entering the planet’s orbit involved a critical and tricky manoeuvre, Mars orbital insertion (MOI).

Achieving MOI saw the spacecraft rotated to position for a deceleration burn of 27 minutes and slowed down from its cruising speed of 121,000km/h to something nearer to 18,000km/h.

During this process it will have burned around half of its fuel.

Going too slow would have meant the spacecraft crashing on Mars, and if it went too fast it risked skipping past the planet.

With an 11-minute one-way radio delay to Earth, the probe had to rely on autonomous self-correcting systems to achieve MOI, managing any exceptional circumstance and mitigating any system failures or performance issues during the operation without human intervention.

News of a signal from the spacecraft was met by applause and cheers, as those in the control room – wearing face masks – maintained social distancing.

Omran Sharaf, Emirates Mars Mission (Hope Probe) project director, Mohammed Bin Rashid Space Centre, said: “MOI was the most critical and dangerous part of our journey to Mars, exposing the Hope probe to stresses and pressures it has never before faced.

“While we have spent six years designing, testing and retesting the system, there is no way to fully simulate the impacts of the deceleration and navigation required to achieve MOI autonomously.

“With this enormous milestone achieved, we are now preparing to transition to our science orbit and commence science data gathering.”

After the gravity of Mars captures Hope it will enter a phase called the capture orbit.

The capture orbit takes the spacecraft from a distance of 1,000 to 49,380km from Mars’s planetary surface.


In this phase instrumentation will be tested and the spacecraft will, over the coming two months, transition to its science orbit.

The transition to Hope’s science orbit will be completed by April 2021.

The probe has a 20,000–43,000km elliptical science orbit and completes one orbit of the planet every 55 hours.

While it will be in daily contact with Earth during the capture orbit phase, in its science orbit contacts will take place two to three times a week.

It will take six to eight hours each time for data to be downloaded and updates and instructions to be uploaded.

The spacecraft will explore the atmosphere of the planet, something that has not been done by any previous probe to the planet.

Hope will aim to answer a number of questions, including how conditions throughout the Martian atmosphere affect rates of escape of hydrogen and oxygen – the building blocks of life.

And how the Martian exosphere (upper atmosphere) behaves at different times during the day and at different distances relative to Mars.

The instruments on board will collect different data points on the atmosphere to also gauge seasonal and daily changes.

Sarah Yousef Al Amiri, minister of state for advanced technologies, chairwoman of the UAE Space Agency, said she hopes the mission will be in a position to share data by September.

The Emirati mission is meant to inspire youth as the country attempts to move away from oil production activities and to embrace new industries. Several United States institutions collaborated on the research, and the UAE spent years preparing for the mission by talking with experienced Mars engineers.

Fulani herdsmen go soon go Mars with there Cow make dem go chop grass...

Buhari, Lai Mohammed, Garba Shehu, Femi Adesina don't like this kind of news.

very soon they will build hotel there

andyblinks:
very soon they will build hotel there

And we will be dragging road with cattles in Nigeria

BeeBeeOoh:
And we will be dragging road with cattles in Nigeria

na our mentality dey kill us nobi religion

But here they told us to start rearing cattle

mars wey me dey go every week

Fahdiga:

Na cow they wan use enter mars nau

You will never hear this kind news from this part of the World.

New worry, By 2070 we go start to dey hear am

Wow, I'm surprised i didn't see them pass my side in Mars, but kudos to you guy's,maybe I'll come over to your orbit so we can plan tomorrow's dinner

apart from insulting PMB, what other thing are you good at?

See small UAE that year. This life get as e take be.

People they embrace new technologies, we still dey year dey fight cow wen dey follow us dey drag road

inoki247:
Fulani herdsmen go soon go Mars with there Cow make dem go chop grass...

Na wahala dem go carry go mars....Fulani nd trouble making are like 5 nd 6

Ok

UAE that was developed & transformed from a desert in the 1980s have attained this feat without any noise making while the so called giant of Africa is still wallowing on its belly since 1960.

Meanwhile, Nigeria's minister of science and technology is telling us that we will be producing pencils in 2020 and that revalidation of APC membership will create employment.This tells the kinds of imbeciles Nigeria is cursed with.

Efforts to colonise Mars are really picking up pace

China's Tianwen-1 craft arrives mars tommorow while the US's Mars 2020 will arrive next week

Funny enough,the same day UAE launched that rocket was the same day BBN season 5 was launched

Good for them. Africa is cursed.

It remains humans. If machines can do it, we can.
