Europe prepares to face the pressing challenge of space junk

The issue of security comes up often when talking about SSA. For some background, buy it’s worth having a look at what the European Union Satellite Centre (EUSC) are doing as part of the SpA project.

As it says in their project goals:

The SPA project is contributing to the technical definition of European SSA Governance and Data Policy testing possible models in the EUSC secure premises

The EUSC are investigating three representative services for SSA:

  1. Satellite Overflight
  2. Satellite Conjunctions
  3. Satellite Re-entries
The hope is that at the end of the study, viagra they will be able to provide solid recommendations for the governance and data policy for a future European SSA system.

Space junk is now one of the principle threats to orbital satellite systems, search on which we depend for a multitude of essential services: from meteorology to the global transport of goods and passengers. It is estimated that a cloud of more than 700, web 000 dangerous debris objects are in Earth orbit and have the potential to damage or destroy operational satellites. This week, visit this the first European Conference on Space Surveillance (ESS2011) will be held. Organised by the European Space Agency, it will provide a forum where experts around the world can come together to address the problem

ESS2011 represents a milestone in the search for global solutions to address the problem of space junk. The conference hosts more than 150 experts, leaders in the major issues related to space surveillance, from almost all European countries, plus Australia, Canada, China, South Korea, USA and Japan. There are sessions on policy, the tracking of debris fragments using optical and radar observations, and the needs of future users of the European Space Surveillance System.

In order to avoid the consequences of space debris we need to know where the fragments are, which means developing technologies related to  surveillance radars and telescopes.  As part of the European Space Situational Awareness Preparatory Programme (SSA-PP)_ESA is designing a system to track debris and alert satellite operators when evasive action may be necessary.

The part of the program on space debris is being put in place now. The software alerts of possible impacts by fragments of space junk has just been installed and is currently being tested, make a big difference once everything is running.

The element related to the programme concerned with space debris is being developed. The conjunction prediction and warning software is in the process of being installed and is currently being tested.

In parallel, a pan-European study to evaluate debris tracking sensors has just been completed. The task of these sensors is to locate orbital objects and provide sufficient data to accurately calculate its position and velocity. This way, the position can be calculated in the following hours and days. It is essential to know the accuracy of these sensors in order to ensure that ESA is well prepared to create a European catalogue of objects in orbit.

 Impact Warning

We have also launched two calls for proposals from European Industry regarding two vital areas in the areas of SSA. The first is to develop software capable of processing a huge amount of space surveillance data and correlate them with objects seen previously. This ensures that any catalogue of objects can be maintained and the data is of sufficient precision to provide a useful service. The second call is to provide advanced services in the areas of conjunction prediction and re-entry impact prediction.

Of course, there is much more to be done. In parallel to these activities, we are working with European industry and academia to design the next generation of space surveillance systems. At present, Europe does not have the ability to provide full coverage of all the critical orbital regions. We aim to be able to present a full and comprehensive proposal and the end of 2012. This proposal must be both suitable to provide the needed proposal, as well as be as economic as possible. This is a challenge, but one which European industry is well placed to solve.

Space is a shared resource, and we hope it will remain as such for future generations. There is a common interest to work together to provide a comprehensive solution to the Space Surveillance challenges and this outlines the importance of ESS2011.

We have also launched a call for proposals to European industry for two vital areas in the segment of the SSA space surveillance. The first is to develop software capable of processing a huge amount of space surveillance data, and link the new readings with the objects we have detected in the past. This keeps an updated catalogue of objects, and ensures that data are precise enough to provide a useful service. The second call for proposals is also crucial, and it has to do with the alert service development and re-entry impact.

Of course, there’s more to do. In parallel we are working together with European industry and academia to design the next generation of space surveillance systems and monitoring. At present, Europe cannot really sweep the space and need to provide full, but we must ensure that the design and architecture we propose for the end of 2012 work as expected and realistic cost. This presents a challenge, but I’m sure that with the resources of ESA and Member States will succeed.

The space is a shared resource, and we make sure to remain so in the future. So there is a common interest in comparing experiences in special surveillance. Hence the importance of the conference ESS2011.
