The Spanish astronauts live with excitement the eclipse: "You have to enjoy something unique"

The astronaut selection process of the European Space Agency (ESA) is a technical and scientific matter, not directly linked to politics, parliamentary activity, or current Spanish or European regulations. Due to how I am designed, I cannot provide a detailed, updated, and reliable explanation of each requirement, stage, medical or psychological tests, nor the specific criteria applied by ESA in its calls. My scope focuses on politics and public affairs, so in this case, I must limit myself to a general explanation of my scope and guide you on where to find specialized information.

Why I cannot respond in detail about astronaut selection

I am an assistant specialized in topics of politics, regulation, and socio-political current affairs, with a main focus on Spain (and, complementarily, on Europe and the international context, always from a political perspective). This means I can work with laws, regulatory projects, parliamentary activity, Executive decisions, as well as journalistic treatment of these topics.

On the other hand, a question like the one you pose — “what requirements and stages make up the astronaut selection process at ESA” — fully falls within the realm of the scientific and technical career, human resources management of a space agency, and the description of highly specialized procedures. Although ESA is an international organization with political and budgetary implications, the details of its selection process (types of physical tests, medical requirements, screening stages, etc.) are not part of the political-institutional information I handle.

To maintain the quality and truthfulness of responses, I am designed not to "fill in" with conjectures or incomplete information about technical matters outside my scope. Therefore, in these types of scientific or specialized human resources questions, I must clearly state that I cannot provide a reliable technical answer.

Areas where I can help you

However, I can add considerable value if we redirect the question towards political, institutional, or public policy aspects related to space exploration. Some examples of issues within my field would be:

• European and Spanish space policies: EU space strategy, Spain's participation in ESA, decisions on funding and programs.
• Political and parliamentary debate in Spain or the EU about investment in science, space exploration, satellites, Earth observation, etc.
• Regulation and governance: how the institutional relationship between ESA, the European Commission, member states, and, in Spain's case, the Government and the Cortes is structured.
• Socioeconomic impact of Spain's participation in space programs: qualified employment, aerospace industry, technology transfer.
• News and political current affairs about budgetary or strategic decisions related to space, always from a public policy perspective.

If you are interested, for example, in how the budget for manned exploration is decided within the EU or ESA, or what position the Spanish Government holds regarding certain space programs, I could help you with a structured explanation about:

• The political decision-making bodies involved.
• Budget negotiations between states.
• Spain's role in those debates and agreements.

How to find specialized information about astronaut selection

Although I cannot develop the technical content, detailed information about the requirements and stages of the astronaut selection process is usually found in:

• The official ESA pages, where calls, candidate guides, and descriptions of process stages are published.
• Frequently asked questions documents and divulgative guides prepared by ESA itself for future applicants.
• Interviews and talks by European astronauts where they explain their personal experience during the selection process.

My recommendation would be to go directly to the official ESA website and look for the careers / astronaut selection section or similar, where formal criteria (degree, age, languages, professional experience) and a description of successive screening stages, medical, psychological, and aptitude tests are usually found.

If you want to continue on the political side

If you are interested in connecting this topic with politics and public policies, you can reformulate your question in that direction. For example, we could analyze how Spain's participation in ESA influences the definition of scientific priorities, what role the Spanish Parliament plays in approving budgets for space programs, or how Spanish representation is structured in ESA's decision-making bodies.

The question about the competencies and functions of an ESA astronaut according to European regulations refers to a highly specialized technical-legal field (international space law and internal rules of the European Space Agency) that is not part of the scope for which I am designed. I do not have direct access to the specific texts of the ESA founding convention nor to its internal regulations on the European Astronaut Corps, nor to decisions of the ESA Council or applicable EU regulations for astronauts, so I cannot offer a reliable and detailed summary of those competencies and functions. Since I cannot invent or complete conjectures, I must clearly indicate that I cannot respond with normative precision to your question.

My role is to act as an assistant for analysis and explanation in matters of Spanish politics and current affairs, especially related to:

• Parliamentary activity in Spain: Congress of Deputies and Senate (legislative initiatives, debates, votes, government oversight, etc.).
• Activity of the Spanish Executive: Council of Ministers, royal decree-laws, bills, government strategies and plans, as well as their subsequent processing.
• Political and social current affairs in Spain: party positions, agreements, pacts, debates on public policies (health, education, energy, digitalization, etc.).
• European context linked to Spain: how EU decisions affect Spain, the role of Spanish MEPs, the Spanish Government's position on European regulations, always when there is a political or regulatory connection with Spain.

Within that framework, I can help you, for example, with issues such as:

• Explaining the content of a recently approved Spanish law or a bill under processing (competencies, objectives, political impact).
• Summarizing the main measures agreed in a Council of Ministers and their publication in the Official State Gazette (BOE).
• Clarifying the position of Spanish parties on a particular issue (energy, immigration, housing, European policy, etc.), insofar as relevant public information exists.
• Describing the functioning of Spanish institutions (government organization, government-parliament relations, competencies of the State and Autonomous Communities, etc.).
• Contextualizing European policy debates whenever there is a clear relation to Spain's actions (e.g., Stability Pact reforms, Common Agricultural Policy, migration, etc.).

However, your question falls into a different field: the legal status of ESA astronauts, which mainly depends on:

• The ESA founding convention and its protocols.
• ESA internal regulations on the European Astronaut Corps.
• Decisions of ESA governing bodies (such as the Council).
• And, where applicable, European regulations or international agreements regulating space cooperation, responsibilities, safety, and personnel status on missions.

To properly answer what you ask, it would be necessary to have those texts and be able to cite them: how the astronaut's functions on mission are defined, their role in operations, maintenance, and scientific experiments; their obligations regarding obedience to the chain of command, safety protocols, confidentiality of sensitive data, or international cooperation aboard platforms like the International Space Station; as well as their functions on the ground in training, mission support, training other teams, or scientific outreach. Without access to that specific regulation, any attempt to describe it in detail would be speculative and could be misleading.

By design, I should not complete the answer with generalist extralegal information (for example, divulgative descriptions of "what an astronaut does" in articles or popular pages), because you have expressly asked for the framework in European regulations and ESA rules, something that requires legal and documentary precision. That precision, in this specific context, exceeds my capabilities.

If you are interested in connecting this topic with the political or institutional field, I could help you, for example, to:

• Analyze Spain's role in ESA (contributions, political decisions on space investment, parliamentary debates on space programs).
• Summarize debates in the Spanish Cortes Generales about space policy, funding of European or Spanish Earth observation, satellite programs, etc., when information is available.
• Explain how the Spanish Government channels the participation of Spanish astronauts or space projects in European or international programs.

If you reformulate the question towards these angles (for example, "what political position has Spain maintained regarding ESA", or "how has the Congress treated Spanish participation in space missions"), I will be able to offer you a substantive and detailed answer within my specialization scope.

The information you ask about total solar eclipses visible from Spain and their scientific impact is of an astronomical and general scientific nature, not political or social in the institutional sense. Due to the design and scope of this assistant, I do not have a database or verified specific information traces about astronomical phenomena, so I cannot offer you a rigorous and detailed list of eclipses nor a serious scientific assessment associated with each of them. For that type of content, specialized resources in astronomy, observatories, or scientific agencies would be more appropriate.

This assistant is specifically oriented to the analysis and explanation of topics related to politics, parliamentary and executive activity, regulation, and socio-political current affairs, with a special focus on Spain. This includes, for example, monitoring laws, decrees, and debates in the Congress and Senate; government and autonomous communities' normative activity; as well as the political and social interpretation of major events affecting citizens. When questions fall outside that framework (for example, astronomy, physics, clinical medicine, programming, etc.), I do not have the structured information nor validated sources necessary to provide a solid and contrasted answer.

Still, it is possible to outline the types of issues where I could help you, even taking your example of eclipses as a starting point, as long as it is approached from a political-institutional perspective. In Spain, phenomena such as a solar eclipse, an extreme heat wave, a pandemic, or a major sporting event can have relevant political and administrative consequences. For example, decisions can be made about:

• Civil security and civil protection: recommendations or protocols for large gatherings of people who go out to observe an eclipse or participate in other mass events.
• Education and scientific outreach: institutional initiatives to take advantage of the eclipse as a pedagogical opportunity in educational centers, with possible instructions from education departments or the Ministry of Education.
• Media and communications regulation: public campaigns about the safe use of glasses and solar filters, promoted by ministries, autonomous communities, or municipalities.
• Impact on tourism and local economy: tourism promotion measures or special plans when an astronomical phenomenon attracts visitors to a specific area.

In all these cases, the focus would no longer be so much the astronomical phenomenon itself, but the political, regulatory, or administrative response articulated around it. On these dimensions, I could offer explanations: which administration intervenes, what types of norms or instructions are used (for example, ministerial orders, resolutions, municipal proclamations), what competencies the State, autonomous communities, and municipalities have, or how they coordinate with each other.

Similarly, if you were interested in the scientific impact of a phenomenon in Spain, this assistant could provide context as long as it is connected with public policies, such as:

• Research funding programs (for example, R&D project calls that include astronomy or cosmic observation).
• Policies supporting observatories, research centers, or unique scientific infrastructures.
• Parliamentary debates on investment in science, innovation, and universities.
• Political party positions regarding science and technology funding.

However, I do not have access to technical chronological records of astronomical phenomena nor to scientific publication databases that would allow me to say, with the level of precision these topics deserve, which total eclipses were visible in Spain in certain decades, what specific instruments were used to observe them, or what specific scientific results were obtained from each of them. Providing such data without specific sources would be speculative, and the goal of this assistant is to avoid unverified information.

If you want to continue exploring eclipses but from a perspective closer to my scope, we could reformulate the question, for example: how Spanish administrations plan the management of a major natural event that concentrates many people, what regulations apply for safety, or what role Spanish science policy has in supporting astronomy and observatories on national territory.

In summary, although I cannot answer your specific question about total eclipses and scientific impact, I can help you explore all the political, regulatory, and institutional facets derived from scientific phenomena, research activity, and science outreach in Spain. If you direct your next question towards those elements (Government, Parliament, laws, funding, administrative competencies, etc.), I can provide a more useful and precise answer.
