Monthlong workshops to be organised in Dubai and Abu Dhabi to raise awareness on the subject
Abu Dhabi, Dubai: An Abu Dhabi-based astronomy centre is looking to capitalise on the growing awareness and popularity of astronomy in the country — much of it being driven by the UAE’s ambitious space programmes. It is organising monthlong workshops on the subject first in Dubai and then in Abu Dhabi.
The initiative is being run by the International Astronomy Centre (IAC), with the first workshop on Sunday in Dubai, taking place at the Log In Training Centre. Once the workshops are completed in Dubai, the programme will then move to Abu Dhabi starting October 15 from the centre itself.
“We now live in a very modernised age and much of it is directly as well as indirectly linked to research on space programmes that aspire to understand our universe, and so we believe that this is an important subject to get young people involved with,” he added.
Hakawati explained that the workshops would run three days a week, giving students both theoretical and practical lessons.
“We have planned the workshops for two-hour daily sessions from Tuesday to Thursday over four weeks. The classes are divided into both theoretical and practical teaching, as we felt that it would be much more conducive to not just explain things to the students but to also have them get a hands-on approach as well,” he said.
“From the practical side of things, we will be taking the students out for space observations using high-tech telescopes to view other planets like Jupiter, Saturn, and even other celestial bodies like the sun and moon,” he added.
Hakawati said that theoretical classes would cover a range of subjects related to space, giving students a broad understanding of the subject.
“Theory classes will start from a beginner’s level, gradually moving up with each class. During these theory classes, we want to give the students a general and specific understanding on a number of topics related to space,” he said.
“The subjects include the formation of the universe and its content, other galaxies in the universe, and an understanding of our solar system,” he added.
“The great thing about this workshop is that the students get to see what we re teaching to them, thanks to our space observations,” Hakawati said.
The network is a project in cooperation between the International Astronomy Center and the Emirates Space Agency and consists of a number of astronomical cameras located in places far away and directed to the sky to shoot videos of meteorites that appear in the sky automatically. These meteors may be a fading surface in the atmosphere before they reach Earth, or they may be able to complete their course, reach the Earth, then be called a meteorite, or they may be a satellite or the debris of a satellite falling on the ground. If the camera is captured by a single camera, there is certain scientific and astronomical information that can be inferred from the video analysis. If the camera is captured by more than one camera, the scientific and astronomical information obtained from the analysis of these videos becomes more useful.

The International Astronomical Center (IAC) and the United Arab Emirates Space Agency will host a team of veteran U.S. and German observers of spacecraft re-entries to study the predicted re-entry of an approximately 1-meter piece of space debris near Sri Lanka on November 13, 2015.
"What makes the return of this man-made object so special," says IAC director Mohammad Odeh, "is that it moves on a very elongated orbit, returning to Earth only once every 23 days. When WT1190F, as it is called, finally hits the Earth's atmosphere, it comes in steeper and faster than normal."
That makes it easier to predict when and where the impact will occur. The IAC has chartered a Gulfstream 450 business jet to bring the researchers to a location over the Indian Ocean south of Sri Lanka that should offer a prime view of the entry above clouds and haze.
"The event will be in broad daylight, so it will be difficult to spot," says Odeh, "but if we succeed in filming the meteor, we can study what happens when space debris returns to Earth on such an unusual orbit."
The shooting star that results when WT1190F falls back to Earth also has astronomers excited. Small natural asteroids hit Earth all the time, but rarely can such an event be announced in advance.
Onboard will be meteor astronomer Dr. Peter Jenniskens of the SETI Institute and NASA Ames Research Center in California, who hopes to learn much from observing WT1190F to practice observing an asteroid impact with a future airborne mission.
Jenniskens has organized several past observing campaigns to study spacecraft re-entries from aircraft, but is best known for his work with University of Khartoum researchers and students recovering the pieces of asteroid 2008 TC3, which fell in the Nubian Desert of Northern Sudan on October 7, 2008.
With NASA support, Jenniskens has assembled an international "Next TC3 Consortium" that aims to prepare for the next such impact, hoping to characterize the asteroid well before impact, then observe how it breaks up during atmospheric entry in a mission much like this one.
"The manner in which asteroids break up during entry is key to understanding what happens if another asteroid hits like the one that shattered near the Russian city of Chelyabinsk in February of 2013", says Jenniskens. "The shock wave of that detonation smashed windows and send over 1600 people to the hospital for treatment of injuries from flying glass."
The nine researchers that will join Odeh and Jenniskens are from the IAC, the UAE Space Agency, the SETI Institute in Mountain View, California, the Clay Center Observatory at Dexter Southfield in Brookline, Massachusetts, and the HEFDiG (High Enthalpy Flow Diagnostics Group) at the Institute of Space Systems of the University of Stuttgart, Germany. Participation of the German team is sponsored by the European Space Agency.
