Los primeros pasos
• La selección de las misiones se hace con un
Call for Proposals
• Se cuenta con unos 3.5 millardos de euros para 10
años. Es decir unas 3 misiones L y 5 misiones M.
• Esto implica una llamada cada 3-4 años por unos
1000 millones de euros en cada una (2007, 2010 y
2013?)
• Las misiones volarán unos 10 años después (entre
2017 y 2025)
• Hay un proceso de selección en marcha con
propuestas recibidas hasta el 29 de junio.
• Dos tipos de propuestas (se seleccionarán 3 + 3):
Misiones medias (300 M) y misiones grandes (650 M)

Fase de viabilidad
• Mostrar para las misiones: valor científico, viabilidad
técnica y que son realistas dentro del programa.
• Se forma un Study Science Team con científicos externos,
incluyendo a los proponentes.
• Se confirman objetivos científicos y requerimientos.
• Definir el perfil de la misión (lanzador, plataforma, órbita,
programa tecnológico y operaciones) y el modelo de
carga útil.
• Definir el escenario de implementación y posibles
cooperaciones.
• Estimación del calendario y costo de la misión
• Duración de unos 2 años.
Programas Tecnológicos
La ESA tiene 3 programas tecnológicos:
• GSTP (opcional para los países)
• TRP (financiado por el presupuesto general)
• CTP (financiado por el programa de ciencia)
GSTP = General Support Technology Programme
TRP = Technology Research Programme
CTP = Core technology Programme
Fase de viabilidad
• Las misiones grandes inician un programa tecnológico
hasta asegurar la necesaria madurez en la que se basa
la selección final.
• Producción de un informe final
• Evaluación de las misiones en Noviembre de 2009
• El SSAC (finalmente el SPC) recomienda dos por clase
para la fase de definición.

Fase de definición
• 2 estudios industriales paralelos iniciados para la
definición de cada misión
• La industria incorpora los desarrollos tecnológicos (en
marcha o planificados) en el diseño del sistema.
• Selección de la carga útil a través de un Announcement of
Opportunity.
• Al final de la fase de definición, se acuerdan las interfaces
con la carga útil (PI) y se hacen propuestas vinculantes
para la fase de implementación en respuesta a una ITT
• Esta fase dura generalmente unos 3 años pero se
propone de sólo 2
• El Study Science Team, para vigilar los objetivos
científicos, pasa a un Science Working Team.
Fase de definición
Carga útil:
• Se aprueba el Science Management Plan (SMP) por el
SPC definiendo las responsabilidades de los que
respondan al AO de la carga útil
• Se hace un Announcement of Opportunity (AO) para
seleccionar la carga útil científica
• Las propuestas se someten a peer review siguiendo tres
criterios:
• Calidad científica
• Viabilidad y madurez tecnológica
• Plan de gestión y financiero
• Los resultados son apoyados en su caso por el SPC y
confirmados por las agencias financiadoras.
Fase de definición
Carga útil:
• En el nuevo plan se propone mantener el desarrollo de
cargas útiles, con fondos nacionales, para dos misiones
en paralelo.
• Los PIs acuerdan con la ESA y la industria el programa
de entrega de instrumentos (a través de acuerdos EID)
• También se seleccionan mission scientists, o
multidisciplinary scientists, a la vez que la carga útil.
• Esta prevista la publicación del próximo Announcement of
Opportunity para 2010 !

Fase de implementación
• El SPC debe decidir ahora sobre el inicio de la
implementación o no, con:
• Una carga útil seleccionada y comprometida.
• Una ITT publicada para el contratista principal de la plataforma.
• Un CaC evaluado adecuadamente.
• Problemas posibles encontrados en la fase de
definición:
•
•
•
•
•
La ciencia no se cubre adecuadamente.
La carga útil no tiene la financiación necesaria.
El CaC necesario es mayor que lo inicialmente previsto.
Existen retrasos graves e inevitables.
Algunas cargas útiles tienen que ser conseguidas directamente
por la ESA con la industria o se tiene que formar un consorcio
no competitivo.
Fase de implementación
• Solo una de las misiones en definición pasa a
implementación.
• El comienzo de esta fase implica “no retorno”.
• Hay un contratista principal seleccionado entre los
involucrados en la fase de definición.
• La duración de esta fase es de unos 5 años.
Fase de implementación
• Las operaciones científicas se definen mediante un
Science Implementation Requirements Document
(SIRD) y su respuesta como Science Implementation
Plan (SIP).
• Los PIs dedican la mayor parte del tiempo al desarrollo
de su contribución a la carga útil (con todos los
problemas clásicos de financiación, ESA, industria, etc.)
Fase de explotación
• Para las nuevas misiones se estima el inicio a mediados
de 2017 (M) o el otoño de 2018 (L)
• En el caso de misiones tipo observatorio se publican
nuevos Announcement of Oportunity para la distribución
de tiempo de observación.
Resumen
• El diseño de instrumentos científicos es una etapa necesaria
después de haber demostrado ser buenos usuarios.
• La mejor ciencia requiere nuevas tecnologías y no una
simple repetición, es decir, innovación.
• Hacer instrumentos es enormemente gratificante.
• Hay que ser consciente que el numero de papers disminuye.
• Trabajar con ingenieros es también una gran experiencia. El
intercambio de conocimientos y culturas enriquece a ambos.
• La interacción de culturas diferentes exige procedimientos
sólidos y documentación detallada.
• El traspaso de ideas a otros campos es posible con
programas de instrumentación
