UAE plans to launch Mars probe Friday after weather delay

Emirati 'Hope' probe heads for Mars
Dubai (AFP) July 14, 2020 - The first Arab space mission to Mars is scheduled to blast off from Japan Friday on a mission to unravel from above the weather dynamics in the Red Planet's atmosphere.

The unmanned probe named Al-Amal -- Arabic for Hope -- is to take off after a two-day weather delay, marking the next step in the United Arab Emirates' ambitious space programme.

Here are some facts and figures about the oil-rich nation's project, which draws inspiration from the Middle East's golden age of cultural and scientific achievements.

- Outsize plans -

The UAE, made up of seven emirates including the capital Abu Dhabi and freewheeling Dubai, has nine functioning satellites in orbit with plans to launch another eight in coming years.

In September, it sent the first Emirati into space -- Hazza al-Mansouri, who was part of a three-member crew. They blasted off on a Soyuz rocket from Kazakhstan, returning home after an eight-day mission in which he became the first Arab to visit the International Space Station.

But the UAE's ambitions go well beyond that, with a goal of building a human settlement on Mars by 2117.

In the meantime, it plans to create a white-domed "Science City" in the deserts outside Dubai, to simulate Martian conditions and develop the technology needed to colonise the planet.

Under a national space strategy launched last year, the UAE is also eyeing future mining projects beyond Earth and space tourism, and has signed a memorandum of understanding with Richard Branson's space tourism company Virgin Galactic.

- Hope's journey -

The next milestone is the launch of the "Hope" probe, which officials say is designed to inspire the region's youth and pave the way for scientific breakthroughs.

The 1,350-kilogramme (2,970-pound) probe -- about the size of an SUV -- was due to blast off from Japan's Tanegashima Space Center Tuesday at 2051 GMT but poor weather delayed lift-off until later in the launch window, which runs until August 13.

The UAE government said the new launch date was set for 5:43 am Japan time on Friday (2043 GMT Thursday).

The probe is expected to detach from the launch rocket about an hour after blast-off.

Unlike the other two Mars ventures scheduled for this year, including Tianwen-1 from China and Mars 2020 from the United States, the UAE's probe will not land on the Red Planet but orbit it for a whole Martian year -- 687 days.

Hope will take seven months to travel the 493 million kilometres (307 million miles) to Mars, in time to mark the 50th anniversary of the emirates' union in 2021.

Once in orbit, one loop will take 55 hours at an average speed of 121,000 kph, while contact with the UAE command and control centre will be limited to six to eight hours twice a week.

- Study and inspire -

Three instruments mounted on the probe will provide a picture of the Mars atmosphere throughout the Martian year.

The first is an infrared spectrometer to measure the lower atmosphere and analyse the temperature structure.

The second is a high-resolution imager that will provide information about ozone levels. And the third, an ultraviolet spectrometer, is set to measure oxygen and hydrogen levels from a distance of up to 43,000 kilometres from the surface.

Understanding the atmospheres of other planets will allow for a better understanding of the Earth's climate, officials say.

But the project is also designed to inspire a region too often beset by turmoil, and recall the heyday of scientific advances during the Middle Ages.

"The UAE wanted to send a strong message to the Arab youth and to remind them of the past, that we used to be generators of knowledge," Omran Sharaf, the mission's project manager, told AFP.

The United Arab Emirates said it plans to launch its "Hope" Mars probe on Friday local time from Japan's Tanegashima Space Center after a two-day delay due to poor weather there.

A rocket is due to blast off at 5:43 am local time (2043 GMT Thursday) carrying the unmanned spacecraft that is bound to orbit the Red Planet in the Arab world's first interplanetary mission.

The launch was postponed from 2051 GMT Tuesday because of inclement weather at the remote Japanese launch site, but remains well within the launch window which runs until August 13.

The Emirati project is one of three racing to Mars, including Tianwen-1 from China and Mars 2020 from the United States, taking advantage of the period when the Earth and Mars are nearest: some 55 million kilometres (34 million miles) apart.

"Hope" -- or Al-Amal in Arabic -- is expected to reach Mars's orbit by February 2021, marking the 50th anniversary of the unification of the UAE, an alliance of seven emirates.

Once there, it will loop the planet for a whole Martian year, or 687 days.

The probe is expected to detach from the launch rocket about an hour after blast-off, which is when the UAE Mars mission's deputy project manager Sarah al-Amiri said the real excitement will begin.

"In my heart of hearts, I'm looking forward to the initial 24 hours after separation, and that's where we see the results of our work," said Amiri, who is also Minister of State for Advanced Sciences.

"It is when we first get the signal, when we know that every part of the spacecraft is functioning, when the solar panels are deployed, when we hit our trajectory and are headed towards Mars," she told AFP earlier this month.

Keiji Suzuki from Mitsubishi Heavy Industries, which is carrying the Hope probe into space, had already warned on Monday that thunderstorms forecast could delay the launch.

- Big ambitions -

The UAE -- which is better known for its skyscrapers, palm-shaped islands and mega attractions -- has in recent years been pushing to expand its space sector.

While the objective of the Mars mission is to provide a comprehensive image of the weather dynamics in the Red Planet's atmosphere, the probe is a foundation for a much bigger goal -- building a human settlement on Mars within the next 100 years.

The UAE also wants the project to serve as a source of inspiration for Arab youth, in a region too often wracked by sectarian conflicts and economic crises.

Dubai has hired architects to imagine what a Martian city might look like and build it in its desert as "Science City", at a cost of around 500 million dirhams (135 million dollars).

And last September, Hazza al-Mansouri became the first Emirati in space, part of a three-member crew that blasted off on a Soyuz rocket from Kazakhstan, returning home after an eight-day mission in which he became the first Arab to visit the International Space Station.

Several dozen probes -- most of them American -- have set off for the Red Planet since the 1960s. Many never made it that far, or failed to land.

The drive to explore Mars flagged until the confirmation less than 10 years ago that water once flowed on its surface.

"What is unique about this mission is that for the first time the scientific community around the world will have an holistic view of the Martian atmosphere at different times of the day at different seasons," the mission's project manager Omran Sharaf told Monday's briefing.

"We have a strategy to contribute to the global effort in developing technologies and science work that will help one day if humanity decides to put a human on Mars."

Six decades of missions to Mars
Paris (AFP) July 10, 2020
The six-decade space race to explore Mars has led to some 40 missions, at least half of which have been successful, and still the Red Planet inspires new adventures. A look back at some key Mars missions over the last 60 years: - 1960-1964: Soviet failures - At first, the Soviet Union leads the way, sending probes from 1960, just three years after it launched its first artificial satellite Sputnik I. But it clocks up a string of failures, including Marsnik 1 and 2, the first two probes l ... read more
