23 Septiembre 12 – Madrid – Pilar Pérez

Hace tiempo que el espacio dejó de ser un lugar vacío y solitario. Hoy día, approved ahí afuera hay cantidad de basura espacial excedente de los intentos del hombre por conquistar los rincones del Sistema Solar. De hecho, la Agencia Espacial Europea (ESA) estima que, de los más de 6.000 satélites lanzados desde el comienzo de la era espacial, menos de 1.000 se mantienen operativos, mientras que el resto ha vuelto a entrar en la atmósfera o sigue en órbita abandonado a su suerte. Esa situación, según la agencia, implica un alto riesgo de generar nuevos fragmentos de basura espacial si sus baterías o el combustible que queda en sus depósitos llegasen a explotar. Por eso, han decidido desarrollar un programa de radares que controle esta situación y avise antes de un grave accidente.

[caption id="attachment_3671" align="alignleft" width="300"] A snapshot of debris [image: ESA][/caption]Al menos 16.000 objetos de más de diez centímetros de diámetro y cientos de millones de pequeñas partículas orbitan a velocidades de vértigo alrededor de la Tierra, en muchos casos interponiéndose en la trayectoria de naves espaciales o satélites artificiales y amenazando su integridad física. Estos escombros galácticos son en su mayoría grandes restos de cohetes, viejos satélites ya en desuso o componentes de artefactos espaciales, como motas de polvo o trozos de pintura. La colisión de una nave espacial o un satélite con estos residuos puede suponer un daño grave y costoso de reparar, así como la generación de más fragmentos que se acumularían en torno a la Tierra en forma de basura espacial.

«Un ejemplo sobre el potencial dañino de esos restos, un tornillo de aluminio de apenas dos centímetros que sobrevuele la Tierra a una velocidad de 7,5 kilómetros por segundo tiene un “diámetro letal” suficiente como para destruir un satélite y provocar su explosión, debido a la energía que contiene», explica Emmet Fletcher, director de Vigilancia y Seguimiento Espacial de la ESA. Incluso si no se volvieran a lanzar ya nuevos satélites, las simulaciones muestran que los niveles de fragmentos en órbita seguirían aumentando, situación por la que la ESA justifica la puesta en marcha de su programa Conocimiento del Medio Espacial (SSA).

Gian Maria Pinna, el responsable del segmento Tierra del programa Conocimiento del Medio Espacial de la ESA, explica en qué consiste la puesta en marcha de un conjunto de radares y telescopios que puedan dar la voz de alarma de futuras colisiones y cómo establecer una serie de protocolos de transmisión a las diferentes agencias espaciales internacionales. «Nosotros vamos a adelantarnos a las circunstancias y a prever las situaciones peligrosas. Nos limitaremos a informar a los dueños de los satélites antes de la colisión y serán ellos quienes decidan cómo se modificará la órbita», explica Pinna.

El nuevo radar, que contará con dos centros en las afueras de París, tendrá un coste de cuatro millones de euros y será construido por el centro de investigación francés Onera conjuntamente con cinco socios industriales de España, Francia y Suiza. Las observaciones del radar se cotejarán con las que lleve a cabo el encargado por la ESA al grupo español Indra en 2010. El radar que fabrica Indra es monoestático, es decir, que tiene una única estación desde la que se emiten energía electromagnética hacia un objetivo y analiza la señal que recibe. El nuevo es biestático, lo que significa que la señal se lanza desde un centro de forma continua y el rebote se recibe en otro.
Las mediciones de estos dos centros, muy aptos para detectar objetos que se encuentran en órbitas bajas, se completarán con una compleja red de sensores, que incluirán centros de procesamiento y telescopios ópticos, más adecuados para la detección de desechos que se encuentran en órbitas medias o geoestacionarias. «Además, contamos con el apoyo de distintos telescopios. Trabajamos para ampliar la abertura de sus espejos primarios y que el espectro que nos dejan vislumbrar supere el metro actual, y mejorar así la sensibilidad de detección de cuerpos extraños», explica Fletcher. El objetivo no sólo se ciñe a la basura, sino que también «tiene en cuenta la aparición de meteoritos o asteroides», añade Fletcher.

Papel de España
En este sentido, los expertos destacan el papel de España, con la participación de los telescopios para las órbitas geoestacionarias de la ESA Tenerife –en concreto en el Teide– y de Granada. Asimismo, el radar monostático, que prepara Indra y que será puesto en marcha en los próximos meses, tendrá su sede en la localidad madrileña de Santorcaz. «España lidera parte del programa del control de la basura espacial y es desde el ESAC donde se coordinará el proyecto», apunta Pinna.

One of the issues to be faced when working in the area of space surveillance and the services that this provides is the potential confusion between collision prediction and collision avoidance. Very often, visit web the two themes are combined into one. This can cause a large degree of confusion regarding what people expect of a future European SSA system.

Conjunction Prediction is the process whereby the potential intersection of two orbits is calculated. Depending on the process used, visit web and the number of orbits analysed, this can be a very complex and computationally intensive operation. In addition, it may require the services of specific tracking sensors in order to reduce the uncertainties of the position of the orbital objects being analysed. The knowledge of the objects is limited generally to the most basic factors: the keplerian elements of the object with the mass and the cross-sectional area or the ballistic coefficient.

In addition, the system works more precisely if the gravitational, atmospheric and solar data is well defined and accurate (which, is never true in the future!). This helps the system predict the orbit of the satellites more closely to reality.

The prediction of potential conjunctions is something that can be done by any party that has access to the orbit data.

Conjunction Avoidance is the next step in the process. This is almost always, if not exclusively, performed  by the satellite operator. The reason for this is that the satellite operator is the only entity which knows the current state of the satellite, the manoeuvre capabilities and the operational restrictions which govern when an avoidance manoeuvre can be done. With the right planning (and timing) a good operations team can combine a collision avoidance manoeuvre with a scheduled orbit maintenance burn and hence minimise the amount of fuel that is otherwise spent on a dedicated avoidance operation.

There is, of course, the potential for a close cooperation between both the conjunction prediction and the conjunction avoidance. In many organisations this is exactly what happens. In GSOC in Germany, CNES in France and the European Space Agency, these two groups work very closely together. When a conjunction manoeuvre is planned, it is good practice to perform the conjunction prediction again, but using the planned orbit after the burn has taken place. This way, we can make sure that the satellite will not move into the path of another object.

This is one of the many conjunction prediction capabilities in the ESA SSA programme. The first conjunction prediction prototype allowed a satellite operator to access predicted collision and upload planned orbit changes for additional processing to make sure it’s safe before the burn takes place. The second generation takes this further and automatically calls for additional tracking when a conjunction is detected – reducing the errors in the prediction and hence the number of ‘false alerts’ received by satellite operators and reducing the irreplaceable fuel that is used.

All this goes to make space operations more efficient and safer: longer lifetimes for satellites and less service interruption for satellite customers.

Vigilar la basura espacial

Today (23rd September 2012) an interview with my colleague Gian Maria Pinna and myself was published in La Razon newspaper. The interview was about the problem of space debris, weight loss the steps ESA is taking to tackle this issue and the deployment of the first European radar specifically designed for debris surveillance.

23 Septiembre 12 – Madrid – Pilar Pérez

Hace tiempo que el espacio dejó de ser un lugar vacío y solitario. Hoy día, ahí afuera hay cantidad de basura espacial excedente de los intentos del hombre por conquistar los rincones del Sistema Solar. De hecho, la Agencia Espacial Europea (ESA) estima que, de los más de 6.000 satélites lanzados desde el comienzo de la era espacial, menos de 1.000 se mantienen operativos, mientras que el resto ha vuelto a entrar en la atmósfera o sigue en órbita abandonado a su suerte. Esa situación, según la agencia, implica un alto riesgo de generar nuevos fragmentos de basura espacial si sus baterías o el combustible que queda en sus depósitos llegasen a explotar. Por eso, han decidido desarrollar un programa de radares que controle esta situación y avise antes de un grave accidente.

[caption id="attachment_3671" align="alignleft" width="300"] A snapshot of debris [image: ESA][/caption]Al menos 16.000 objetos de más de diez centímetros de diámetro y cientos de millones de pequeñas partículas orbitan a velocidades de vértigo alrededor de la Tierra, en muchos casos interponiéndose en la trayectoria de naves espaciales o satélites artificiales y amenazando su integridad física. Estos escombros galácticos son en su mayoría grandes restos de cohetes, viejos satélites ya en desuso o componentes de artefactos espaciales, como motas de polvo o trozos de pintura. La colisión de una nave espacial o un satélite con estos residuos puede suponer un daño grave y costoso de reparar, así como la generación de más fragmentos que se acumularían en torno a la Tierra en forma de basura espacial.

«Un ejemplo sobre el potencial dañino de esos restos, un tornillo de aluminio de apenas dos centímetros que sobrevuele la Tierra a una velocidad de 7,5 kilómetros por segundo tiene un “diámetro letal” suficiente como para destruir un satélite y provocar su explosión, debido a la energía que contiene», explica Emmet Fletcher, director de Vigilancia y Seguimiento Espacial de la ESA. Incluso si no se volvieran a lanzar ya nuevos satélites, las simulaciones muestran que los niveles de fragmentos en órbita seguirían aumentando, situación por la que la ESA justifica la puesta en marcha de su programa Conocimiento del Medio Espacial (SSA).

Gian Maria Pinna, el responsable del segmento Tierra del programa Conocimiento del Medio Espacial de la ESA, explica en qué consiste la puesta en marcha de un conjunto de radares y telescopios que puedan dar la voz de alarma de futuras colisiones y cómo establecer una serie de protocolos de transmisión a las diferentes agencias espaciales internacionales. «Nosotros vamos a adelantarnos a las circunstancias y a prever las situaciones peligrosas. Nos limitaremos a informar a los dueños de los satélites antes de la colisión y serán ellos quienes decidan cómo se modificará la órbita», explica Pinna.

El nuevo radar, que contará con dos centros en las afueras de París, tendrá un coste de cuatro millones de euros y será construido por el centro de investigación francés Onera conjuntamente con cinco socios industriales de España, Francia y Suiza. Las observaciones del radar se cotejarán con las que lleve a cabo el encargado por la ESA al grupo español Indra en 2010. El radar que fabrica Indra es monoestático, es decir, que tiene una única estación desde la que se emiten energía electromagnética hacia un objetivo y analiza la señal que recibe. El nuevo es biestático, lo que significa que la señal se lanza desde un centro de forma continua y el rebote se recibe en otro.
Las mediciones de estos dos centros, muy aptos para detectar objetos que se encuentran en órbitas bajas, se completarán con una compleja red de sensores, que incluirán centros de procesamiento y telescopios ópticos, más adecuados para la detección de desechos que se encuentran en órbitas medias o geoestacionarias. «Además, contamos con el apoyo de distintos telescopios. Trabajamos para ampliar la abertura de sus espejos primarios y que el espectro que nos dejan vislumbrar supere el metro actual, y mejorar así la sensibilidad de detección de cuerpos extraños», explica Fletcher. El objetivo no sólo se ciñe a la basura, sino que también «tiene en cuenta la aparición de meteoritos o asteroides», añade Fletcher.

Papel de España
En este sentido, los expertos destacan el papel de España, con la participación de los telescopios para las órbitas geoestacionarias de la ESA Tenerife –en concreto en el Teide– y de Granada. Asimismo, el radar monostático, que prepara Indra y que será puesto en marcha en los próximos meses, tendrá su sede en la localidad madrileña de Santorcaz. «España lidera parte del programa del control de la basura espacial y es desde el ESAC donde se coordinará el proyecto», apunta Pinna.

Space Imaging for SSA

When satellite imaging is mentioned, this site ophthalmologist we usually think of satellites taking pictures of the weather, see floods or downtown New York. This is one of the primary uses of satellites and one which has brought great benefits to many people. Within space surveillance, satellite imaging refers to taking pictures of satellites on orbit. But why would we want to do that?

One reason is when things don’t go as planned. Satellite operators cannot always see what is happening on the satellite directly, but rely on specific sensors to tell them if something has – or hasn’t – worked. This could be a signal to say that the solar panels have been set correctly. If this signal hasn’t been received, it could mean one of two things. Either the solar panel hasn’t been set correctly or the sensor has malfunctioned. But which one of the two is it? Sometimes this specific situation can be verified because there is no power being generated by the solar panel or the satellite’s attitude moves in such a way that indicates the solar panel is not sticking out of the side of the satellite body. In either case, an independant way to verify this would be useful.

Another reason is during re-entry. The way a space object is oriented can effect large changes in the re-entry profile. It can determine if the satellite will break up high in the atmosphere and these small pieces vapourise without touching the Earth’s surface or if the orientation will cause some drag or lift as it comes through the atmopshere and hence change the impact point. Being able to image an object as it comes close to re-entry and begins to be affected by the atmosphere can really help reduce the uncertainty in both these areas.

A final reason why satellite imaging is important is – as can be guessed – military. Having intelligence regarding the capabilities of satellites in orbit is very useful to military commanders. Using satellite imaging could be a good way to do this.

Of course any specific military requirments are out of the scope of the ESA SSA programme. It can be predicted that the resolution required to perform the first two functions of anomaly resolution and re-entry prediction is much less than that required for the third one.

Phobos-Grunt: Interesting ground-based imagery

imageThis is an image taken by Ralf Vandebergh using commercial telescopes as the basis for the observations. This show the power of ground-based telescopes to take images of low-Earth orbit objects. Needless to say, approved the cost of Ralf’s system is probably an order of magnitute (or less) than the cost of a comparable radar-based system.

Of course, opisthorchiasis weather conditions and the illumination conditions from the Sun play a great deal in how good the image will be on any given observation; something that is not generally a problem for radar systems or space-based space surveillance. But I think the work that Ralf shows here is very interesting and could teach a few lessons to more formal systems.

Su nombre es 2005 YU55 y ayer pasó tan cerca de la Tierra (a unos 320.000 kilómetros) que se podía ver con un telescopio.

Este asteroide ha traido a la memoria colectiva las lluvias de rocas espaciales tan habituales en películas como ‘Superman’ o ‘2001 una odisea en el espacio’. Algunos han llegado a vaticinar que su impacto sobre la superficie terrestre podría ser catastrófico. Sin embargo, urticaria los científicos no dejan margen para la imaginación: “Este asteroide va a pasar muy cerca de la Tierra pero no va a impactar. Por lo tanto, buy no es peligroso”, afirma con rotundidad la investigadora Julia León, del Instituto Astrofísico de Andalucía, del CSIC.
Con todo, “es un evento raro, que no suele ocurrir y, según nuestras previsiones, para que otro objeto similar se acerque tanto a nuestro planeta tendremos que esperar hasta 2028 o 2030”, puntualiza la astrofísica.

Objetivamente, sí hay motivos para una cierta alarma. El primero es que se trata de un asteroide grande, de 400 metros de diámetro (más grande que el portaaviones español Juan Carlos I o el Titanic y de la misma eslora que el superpetrolero Esso Pacific), y otro es la proximidad a la Tierra. Como explica León, “un asteroide se considera potencialmente peligroso cuando su diámetro es mayor de 150 metros y se acerca a nuestro planeta a menos de 20 veces la distancia de la Tierra a la Luna”. Y con estos requisitos, hay más de un millar de asteroides catalogados.

Los científicos de la NASA y de la Agencia Espacial Europea (ESA) han hecho un seguimiento minucioso de 2005 YU55. Desde que se descubrió, en 2005, los astrónomos han estudiado su órbita para determinar las posibilidades de que impacte en la Tierra, y la conclusión final es tranquilizadora.

Pero, ¿cómo saber que la información que nos llega es la correcta? Emmet Fletcher, Responsable del programa de Reconocimiento y Seguimiento espacial de la ESA explica que “hay que validar los datos que llegan de grupos independientes. En este caso, lo han hecho la Universidad de Pisa y un centro de Estados Unidos. Después de cotejar sus cálculos comprobaron que coincidían”.

Tal vez, para algunos sea una decepción saber que nuestro planeta no está, de momento en peligro, pero “la cercanía de este asteroide tiene un enorme interés científico, ya que nos permitirá estudiarlo desde tan cerca que podremos ver bien su superficie, estudiar su composición y otros datos que pueden arrojar más luz sobre el origen del universo”, apunta León. “El rádar Goldstone lo podrá observar con una resolución de cuatro metros”.

El astrónomo de la ESA añade que habrá que esperar cien años para que las alarmas vuelvan a saltar. “Son situaciones excepcionales, pero la caída de meteoritos a la Tierra es muy frecuente. Disponemos de cientos de fragmentos que hemos recogido de distintos lugares y que nos ayudan a conocer la composición del universo”.

Métodos de defensa

Aunque por ahora no hay que temer un gran impacto, los científicos trabajan desde hace años en el desarrollo de métodos defensivos para evitar una colisión potencialmente catastrófica. “Lo más sencillo y barato parece ser bombardear el cuerpo peligroso”, indica León, pero “la solución puede ser peor que la amenaza, porque hay que saber como controlar los fragmentos en los que se rompe ese cuerpo”.

Fletcher añade que otra opción sería enviar cohetes capaces de alterar la trayectoria del cuerpo amenazante. “Las soluciones son muy diferentes, pero se necesitan varios años para preparar una estrategia defensiva eficaz”.

700.000 fragmentos de basura espacial catalogados

ABC 06 June 2011

Emmet Fletcher
Space Surveillance and Tracking Manager 

(translated from the original version)

Space junk is now one of the principle threats to orbital satellite systems, thumb information pills 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, viagra here 000 dangerous debris objects are in Earth orbit and have the potential to damage or destroy operational satellites. This week, epilepsy 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

The Earth, surround by space debris (artist impression)

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.

Space junk is now one of the principle threats to orbital satellite systems, more 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, refractionist 000 dangerous debris objects are in Earth orbit and have the potential to damage or destroy operational satellites. This week, page 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.

La Agencia Espacial Europea (ESA) está diseñando un sistema para clasificar y catalogar los más de 700.000 fragmentos de basura que los científicos estiman hay en el espacio, un sistema que pretende evitar colisiones y mejorar la seguridad de los satélites y otros instrumentos actualmente en uso.

Esta es una de las iniciativas de las que se ha hablado en la Conferencia Europea sobre Vigilancia Espacial celebrada esta semana en Madrid, a la que han acudido 180 expertos de varios países. Los investigadores creen que los satélites están amenazados por más de 700.000 fragmentos de basura espacial y para evitar una colisión es necesario conocer y monitorizar su trayectoria con ayuda de radares y telescopios, de ahí que la ESA esté trabajando en un sistema para detectar los objetos espaciales “peligrosos”.

Según ha relatado Emmet Fletcher, responsable del segmento de vigilancia espacial del programa europeo de “Conocimiento del Medio Espacial” (SSA en sus siglas en inglés) de la ESA, actualmente hay en órbita unos mil satélites activos. Lo que ahora trata de hacer la ESA, ha continuado, es generar un catálogo de todos los objetos peligrosos que orbitan la tierra (EEUU tiene clasificados unos 22.000 de estos fragmentos).

Entre los 700.000 trozos que se cree que hay en el espacio, existen desde pedazos de un centímetro hasta satélites enteros ya en desuso y bastaría la menor de estas piezas para estropear un satélite, chatarra que se triplicará en los próximos 20 años. Catalogar es, entre otros parámetros, conocer la posición y velocidad del objeto, con lo que los investigadores saben hacia dónde va y comparan así la órbita de éstos con la de un satélite.

“Podemos calcular si coinciden y si lo hacen podemos dar avisos a los operadores de los satélites para que maniobren con seguridad y con el menor uso de combustible, y evitar el choque”, según Fletcher. Fletcher, quien ha declarado que siempre se intenta avisar al operador lo antes posible -no más tarde de 72 horas antes de la supuesta coincidencia de un pedazo de basura con el satélite-, ha manifestado que la ESA ya está trabajando en el citado catálogo, aunque será en 2012 cuando los países, en una reunión ministerial, den su visto bueno definitivo y se establezca un presupuesto.

Prueba de este trabajo es que recientemente se ha completado el desarrollo de un software de última generación capaz de alertar a los satélites cuando exista el riesgo de impacto con un fragmento de basura espacial. “De momento estamos probando el sistema utilizando datos de fragmentos de basura espacial ya conocidos. Es el primer paso hacia el software que se utilizará cuando Europa disponga de su propia capacidad de vigilancia del medio espacial”, ha afirmado Fletcher.

Este catálogo es una de las tres patas del programa de Conocimiento del Medio Espacial (SSA), cuyo objetivo es desarrollar e implementar un sistema de alerta temprana, pero no sólo respecto a colisiones espaciales, sino también en cuanto a impactos de objetos naturales contra la Tierra y en relación a la meteorología espacial. Desde 2009 se trabaja para definir la estructura técnica del sistema, para lo que primero se está evaluando la capacidad de la infraestructura ya existente en Europa, como radares de investigación científica y telescopios, que podrían incorporarse al futuro sistema SSA.

El programa SSA ha sido otro de los temas debatidos en la conferencia de Madrid, de cuyos resultados Fletcher ha asegurado sentirse satisfecho. “El espacio es un bien común y nos hemos puesto al día”, ha concluido este experto.

Scanning the skies for debris hazards

Today, cost illness orbiting satellites are threatened by some 700, cough 000 pieces of debris. Assessing related risks requires surveillance, neurologist tracking and statistical observations with radars and telescopes. ESA is designing a system to catalogue debris and warn satellite operators when to take evasive action.

This week, over 150 global experts will meet at an ESA-organised conference to share the latest research findings on space debris, surveillance technology, orbital hazard detection and satellite safety. The first European Space Surveillance Conference (ESS2011) will be held 7–9 June in Madrid, Spain.
The conference spotlights ESA’s Space Situational Awareness (SSA) programme, now in the preliminary phase, which aims to put in place a ‘three-legged’ system to warn of hazards posed by orbital debris, space weather and natural objects like asteroids that may strike Earth.

Extensive reuse of existing resources

Since 2009, the Agency’s SSA team have been working to define the system’s overall technical structure, while actively evaluating existing European assets, such as scientific research radars and telescopes, which could contribute to SSA.

The development strategy is based on an extensive use of national and European assets, as well as the procurement of the missing components of the future SSA System.

2011 is a busy year for SSA surveillance development activities, perhaps the most urgent leg of the programme.

Complex engineering and scientific challenge

A new generation of software was recently implemented to warn when satellites could be hit by orbiting debris.

“At the moment, it is undergoing extensive testing using known debris orbits, but it’s a first step toward the software we’ll use when Europe has its own surveillance capability,” says ESA’s Emmet Fletcher, Head of the Space Surveillance and Tracking Segment at the SSA programme office.

Hosting an international conference like ESS2011 is crucial for staying up to date with global best practises and meeting scientific experts who work with current-generation radars and telescopes.

Debris surveillance is a complex engineering and scientific challenge in part due to the fact that even a tiny piece of debris – just 1 centimetre across – can seriously damage or even destroy a functioning satellite if it impacts at orbital velocities.

“We are now finalising a pan-European survey and test of existing tracking facilities, such as radars and telescopes located in France, Germany, Italy, Norway, UK, Switzerland and Spain,” says Emmet.

“Knowing how precise these are is fundamental to designing ESA’s new SSA system, which may make use of their data in combination with debris readings obtained by new, highly accurate radars and telescopes in the future.

“We know there is a huge amount of knowledge across Europe and globally. Having a single forum where experts from around the world can meet and present new information is vital and helps move our collective know-how forward.

“New techniques, new approaches and sharing past experience helps all space-faring nations work more safely in orbit.”

Conference brings together global experts

At the conference, over 150 experts from more than 20 nations will take in over 50 presentations. There are also dedicated information sessions on policy, optical and radar observations, and engineering design as well as presentations from the future customers of the SSA system.

Today, Europe cannot scan as much of space as necessary to provide comprehensive debris warning services to private and public spacecraft operators, like those flying telecommunication, climate and weather satellites.

“But we have to ensure that the design for the next-generation debris surveillance and tracking systems that SSA will propose at the end of the current preliminary phase in 2012 will perform as needed at a cost that is realistic,” says Emmet.

“This is a challenging task, and achieving it means that conferences like ESS2011, involving a large number of experts, are crucial for knowing the best way forward.”
