UK Astronomers Watch the Skies for Threat from Space

13.10.2004


British astronomers are providing a vital component to the world-wide effort of identifying and monitoring rogue asteroids and comets. From this month, the UK Astrometry and Photometry Programme (UKAPP) for Near-Earth Objects, based at Queens University, Belfast, will track Near-Earth Objects (NEOs) and feed their crucial information into the international programme of protecting the Earth from any future impact by a comet or asteroid.



On average 30-40 NEOs are discovered each month - asteroids and comets that could one day collide with the Earth. Over 3000 NEOs have now been found, and a world-wide effort involving professional and amateur astronomers attempts to keep track of these objects. Now a team of astronomers at Queen’s University Belfast will be tracking these objects each week using large high-performance telescopes.

UKAPP is using the Faulkes Telescope North, a robotic telescope on the Hawaiian island of Maui built primarily for educational use by the Faulkes Telescope Project. At the end of this year they will also start using the twin Faulkes Telescope South at Siding Spring, Australia. The telescopes’ mirror size of 2-m allows astronomers to see fainter NEOs than most other facilities regularly used for this task. Test observations took place in September, and the full programme begins in October. The work is supported by a grant from the British National Space Centre (BNSC) and the Particle Physics Research Council (PPARC).


Dr. Alan Fitzsimmons, the project leader, said “Previously we used UK-funded telescopes on La Palma, but for various reasons they could only track a couple of objects per month on average. The robotic nature of the Faulkes telescopes means that it is much easier for us to observe numerous NEOs than can be achieved by using conventional telescopes.” Once the images of the NEOs are taken, Dr Fitzsimmons and his colleagues transfer them to an astronomical computer network in Northern Ireland via the internet. The positions of the NEOs are then measured and communicated to the Minor Planer Center in Harvard in America; the world’s clearing house and repository for measurements of NEOs.

Although most of the time will be spent tracking NEOs, some of the time will also be spent studying their physical make-up. Dr Fitzsimmons said “This is not only scientifically interesting. If we are going to be hit by one of these things in the future, we need as much information as possible to allow us to plan any course of mitigation”.

An important aspect is that school classes and science centres around the country can also do this work. In a separate endeavour from UKAPP, the Faulkes Telescope Project assists school children to track NEOs using specially designed educational projects.

Dave Bowdley, Faulkes Telescope Educational Programmes Manager said, “This project provides a fantastic opportunity for schools to work alongside the professionals in an exciting area of research.”

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
