Abu Dhabi Crown Prince's majlis hears space tale



ABU DHABI // The tale of Yahsat's journey to outer space was told to an audience at the Crown Prince's majlis on Monday.
Jassem Al Zaabi, director general of the National Electronic Security Authority and chairman of Al Yah Satellite Communications Company, spoke of the Yahsat project, from how it began to the day it was launched.
Sheikh Mohammed bin Zayed, the Crown Prince of Abu Dhabi and Deputy Supreme Commander of the Armed Forces, was joined by several officials from the Ministry of Interior and other ministries.
"Why launch a satellite?" Mr Al Zaabi asked. "First for strategic purposes, for communication and support to infrastructure, and for commercial reasons, to enter the international market."
He explained to the majlis attendees that there were three types of satellites: the low earth orbit (Leo), middle earth orbit (Meo), and geostationary satellites (Geo), set to orbit 36,000 kilometres from the Earth's atmosphere.
Yahsat launched a Geo satellite.
Despite the challenges they knew they would face, they set out to realise a mission given to them by the Crown Prince himself.
The first roadblock hit them at the very start of their journey.
"The biggest challenge was not the satellite design, but one all new satellite companies have - to find space to put the satellite in," he said. "Just like using phones and finding networks."
It took them about six years and discussions with 50 countries to secure a site in space for Yahsat. It is currently at 52.5 degrees east.
The company spent three years building the satellite and six months testing it. They tried to "break" it, to ensure it would survive the launch. The first launch attempt failed.
"For the first half an hour, we had no idea the effect it would have on it," Mr Al Zaabi said. "After three weeks, the second launch was perfect."
A second satellite was launched on April 21, 2011, without any problems.
"In six years we turned the idea to reality," he said, encouraging those on missions or working on projects not to despair when faced with challenges.
At Yahsat, 54 per cent of employees are Emirati.

What is graphene?

Graphene is a single layer of carbon atoms arranged like honeycomb.

It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.

Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.

By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.

At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.

It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.

But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.

In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.
