Beyond the Pale Blue Dot, The Next Giant Leap from Pioneers to Permanent Residents—Forging Humanity's Multi-Planetary Future on Mars

1. Introduction: The Historical and Intellectual Crossroads of Martian Settlement

Humanity stands at a threshold unprecedented in its evolutionary history. For the first time, the technological, scientific, and economic conditions are converging to make permanent settlement beyond Earth a tangible possibility. The Red Planet, long a fixture of scientific curiosity and cultural imagination, has emerged as the most viable candidate for humanity's first extraterrestrial colony. However, the transition from sporadic exploration missions to continuous human presence represents a leap of such magnitude that it demands a fundamental rethinking of how we approach spacefaring (Deudney, 2020; Targowski, 2025).

The inaugural volume of Mars Settlement - Journal of Mars Exploration and Settlement arrives at this critical juncture, dedicated to investigating the complex, multifaceted challenges of establishing a sustainable and meaningful human presence on Mars (Mars Settlement, 2026). This journal is not merely another publication in the growing corpus of space literature; it represents a deliberate intellectual intervention aimed at reshaping the very framework through which we conceptualize off-world settlement. The question is no longer if humanity will reach Mars, but how we will remain there—and, more profoundly, what we will become in the process.

This editorial sets forth the journal's intellectual vision: to serve as the premier scholarly platform for research that bridges scientific discovery with human futures, exploration with settlement, and Earth's knowledge with Martian reality. The journal does not merely ask "What is Mars?" It investigates: "How can human life on Mars become possible, sustainable, and meaningful?" (Mars Settlement, 2026). This orientation distinguishes the journal as a scholarly platform that integrates the physical sciences with the humanities, engineering with ethics, and technological innovation with social foresight.

The journal's name—Mars Settlement—is deliberately chosen to signal its forward-looking mission. While many publications focus on the exploration of Mars, this journal is dedicated to the far more ambitious and consequential project of settlement. This shift from exploration to settlement represents a profound conceptual transformation, one that carries immense intellectual, technical, and ethical implications (Mars Settlement, 2026).

2. The Grand Challenge: From Robotic Reconnaissance to Permanent Habitation

The history of Mars exploration has been predominantly defined by robotic missions—orbiters, landers, and rovers that have progressively mapped the planet's surface, analyzed its geology, probed its atmosphere, and searched for signs of past or present life. These missions, from Mariner 4 in 1965 to the Perseverance rover currently operational in Jezero Crater, have laid an essential foundation of knowledge. We now understand Mars as a world with a complex geological history, evidence of ancient water flows, seasonal atmospheric dynamics, and radiation levels that present significant challenges to human health (Balbi & Lingam, 2023).

Yet robotic exploration, however sophisticated, is fundamentally limited. Rovers cannot drill deep into the subsurface, cannot perform complex biological experiments requiring human intuition, cannot adapt to unforeseen situations with the flexibility of human cognition, and most importantly, cannot undertake the construction of permanent infrastructure. The transition to human settlement demands a paradigm shift from exploration to construction, from observation to intervention, from temporary presence to permanent occupation.

This transition introduces a cascade of interconnected challenges that span multiple orders of magnitude in complexity. First, there is the challenge of transportation: developing launch systems, transit habitats, and landing technologies capable of delivering humans and cargo safely to the Martian surface. Second, there is the challenge of immediate survival: providing breathable air, potable water, nutritious food, and adequate protection from radiation and temperature extremes. Third, there is the challenge of long-term sustainability: creating closed-loop life-support systems, utilizing local resources, developing energy infrastructure, and establishing agricultural production (Elvis & Milligan, 2019). Fourth, there is the challenge of social organization: developing governance structures, legal frameworks, economic systems, and cultural practices appropriate for a frontier society. Finally, there is the challenge of meaning and purpose: understanding why we are going, what we hope to achieve, and how we can ensure that Martian settlement enriches rather than diminishes human civilization (Lo Sapio, 2026).

The magnitude of these challenges is difficult to overstate. Mars is a world with a thin atmosphere (1% of Earth's surface pressure), composed primarily of carbon dioxide; daily temperature swings of up to 100°C; galactic cosmic radiation and solar particle events; and fine, abrasive dust that can damage equipment and pose respiratory hazards. The human body, evolved over millions of years for Earth's gravity, atmosphere, and magnetic field, is ill-prepared for Martian conditions. The psychological challenges of isolation, confinement, and the constant awareness of a hostile environment are equally formidable. The political and economic challenges of organizing a global effort to establish a settlement on another world are perhaps the most daunting of all.

3. The Interdisciplinary Imperative: Breaking Down Silos

No single discipline possesses the knowledge, tools, or perspectives necessary to address these challenges. The settlement of Mars is not merely a technological or engineering problem; it is a grand interdisciplinary endeavor that integrates scientific discovery with human futures. The task of creating a permanent foothold on a world as hostile as Mars demands a convergence of knowledge rarely seen in a single field. This is the core intellectual premise upon which this journal is founded.

The journal adopts a broad interdisciplinary perspective, recognizing that establishing a sustainable human presence requires the integration of knowledge across an extraordinary range of fields (Mars Settlement, 2026):

• Planetary science: understanding Mars' geology, atmosphere, climate, surface morphology, magnetic field, water resources (ice deposits), and potential hazards (dust storms, radiation levels).
• Space engineering: developing launch systems, spacecraft, entry/descent/landing technologies, orbital mechanics, and communication networks between Mars and Earth.
• Astrobiology: assessing the potential for Martian life, searching for past or present biosignatures, investigating extremophiles, and ensuring planetary protection.
• Human physiology and medicine: addressing the effects of microgravity and partial gravity (0.38g) on the human body, including bone density loss, muscle atrophy, vision changes, and cardiovascular deconditioning.
• Psychology and human factors: ensuring psychological well-being and team cohesion in extreme environments, addressing effects of long-term confinement, isolation, communication time-lags, and living in cramped quarters.
• Architecture and environmental design: creating habitable spaces that are functional, aesthetic, and conducive to human flourishing, including inflatable habitats, subsurface/lava tube shelters, and regolith-based 3D-printed construction.
• Agricultural science and food systems: developing closed-loop food production in controlled environments, including hydroponics, aeroponics, vertical farming, and microbial food production.
• Materials science: developing advanced materials for construction, radiation shielding, and life support.
• Artificial intelligence and robotics: designing autonomous systems for construction, maintenance, exploration, and habitat management.
• Sociology and anthropology: understanding how human societies form, evolve, and function in new environments.
• Economics: developing viable economic models for off-world resource utilization and trade.
• Law and governance: establishing legal frameworks for extraterrestrial claims, resource rights, and dispute resolution.
• Ethics and philosophy: examining the moral dimensions of space expansion, including duties to future generations and potential Martian life (Chon-Torres, 2026; Lo Sapio, 2026).
• Cultural studies: exploring the cultural narratives, symbols, and practices that will define Martian identity.

This comprehensive interdisciplinary scope ensures that research published in the journal addresses not only the technical feasibility of settlement but also its desirability, sustainability, and meaning. The journal is structured around ten principal areas of inquiry, each representing a critical dimension of the settlement challenge (Mars Settlement, 2026).

4. The Technical Architecture of Settlement: Systems Integration

Perhaps the most critical intellectual contribution of an interdisciplinary approach to Mars settlement is the recognition of systemic interdependence. Every element of a Martian settlement is connected to every other element; changes in one subsystem ripple through all others in ways that must be carefully understood and managed.

4.1 In-Situ Resource Utilization (ISRU)

The concept of in-situ resource utilization—using local resources rather than transporting everything from Earth—is foundational to sustainable settlement. Mars provides carbon dioxide in its atmosphere, water ice in its polar caps and subsurface deposits, and regolith rich in minerals and metals. The extraction and processing of these resources present both immense opportunities and significant technical challenges.

Research has demonstrated that Martian regolith can be processed to extract oxygen, water, and metals. The Sabatier reaction can combine carbon dioxide and hydrogen to produce methane and oxygen for rocket propellant (Elvis & Milligan, 2019). Regolith can be sintered using microwaves or solar concentrators to produce construction materials, potentially eliminating the need to transport building materials from Earth. The extraction of water from subsurface ice is critical not only for human consumption but also for agriculture, oxygen production, and radiation shielding.

The journal's scope on ISRU encompasses water extraction and processing, regolith utilization and material processing, oxygen and fuel production from local resources, construction materials and local manufacturing, resource mapping and assessment, and in-situ manufacturing and additive construction (Mars Settlement, 2026). These are not merely technical challenges; they are foundational to the economic viability and long-term sustainability of a Martian settlement.

However, each of these processes requires energy, which itself must be generated on Mars. Solar power, nuclear power, and potentially wind power must be integrated into a robust and redundant energy infrastructure. The interplay between resource extraction, energy generation, and life support creates a complex system of feedback loops that demands sophisticated modeling and optimization. The journal's energy scope includes solar power generation and storage, nuclear power and advanced energy systems, energy storage and distribution, sustainable and resilient energy systems, and power system reliability and redundancy (Mars Settlement, 2026).

4.2 Closed-Loop Life-Support Systems

Human settlement on Mars requires the development of life-support systems that are highly closed-loop, minimizing the need for resupply from Earth. Current life-support systems on the International Space Station recover approximately 85–90% of water and generate oxygen through electrolysis, but significant carbon dioxide must still be vented and food must be entirely imported.

A true closed-loop system would approach 100% recycling of water, oxygen, and nutrients. This involves integrating biological and physico-chemical processes in a manner that mimics Earth's natural biogeochemical cycles. Plants play a central role in bioregenerative life-support, producing oxygen, absorbing carbon dioxide, and providing food. Research into hydroponic and aeroponic agriculture, algal bioreactors, and waste processing technologies is essential to achieving closed-loop systems.

The journal's scope on life support and sustainability encompasses environmental control and life-support systems, closed-loop ecological systems, water recovery and recycling, oxygen production and air revitalization, waste recycling and resource recovery, and ecological life-support and bioregenerative systems (Mars Settlement, 2026). The technical challenges are formidable. Plants grown in controlled environments require lighting, temperature control, nutrient delivery, and disease management. Algal systems must be carefully regulated to maintain optimal growth rates. Waste processing must convert human metabolic waste, inedible plant biomass, and other waste streams into usable inputs. The energy requirements of these systems must be balanced against available energy resources.

4.3 Habitat Design and Construction

Martian habitats must protect inhabitants from a hostile environment characterized by: a thin atmosphere (1% of Earth's surface pressure), composed primarily of carbon dioxide; daily temperature swings of up to 100°C; galactic cosmic radiation and solar particle events; and fine, abrasive dust that can damage equipment and pose respiratory hazards.

Habitat design must address these threats while also providing functional, comfortable, and psychologically supportive living environments. Habitats may be constructed from regolith-based materials, with thick walls providing radiation shielding. Inflatable structures, modular components, and underground excavation all offer potential solutions. The integration of windows, lighting, and green spaces can support psychological well-being, as can the provision of private and communal spaces.

The journal's scope on habitats includes habitat design and space architecture, underground and surface habitats, radiation shielding and thermal management, structural systems and construction, settlement planning and infrastructure, transportation networks and urban organization, community design and human-centered environments (Mars Settlement, 2026). The design of Martian habitats must also anticipate growth and expansion. Initial settlements will likely be small, but they should be designed to accommodate future growth, with modular expansion and infrastructure capacity. This is where research on ecological succession frameworks offers a compelling vision: settlements evolving from isolated modules into interconnected, feedback-regulated ecological nodes (Lo Sapio, 2026).

4.4 Human Health and Performance

The health and performance of Martian settlers is perhaps the most critical and uncertain variable in the settlement equation. Extended exposure to partial gravity (approximately one-third of Earth's gravity) has unknown physiological effects. Musculoskeletal atrophy, cardiovascular deconditioning, and immune system dysfunction are all known effects of microgravity, but the effects of Martian gravity are poorly understood.

The journal's scope on medicine and human biology includes space medicine and Mars medicine, radiation biology and protection, microgravity and partial-gravity effects, musculoskeletal, cardiovascular, and immunological adaptation, long-duration health monitoring and countermeasures, and medical emergency preparedness and telemedicine (Mars Settlement, 2026). Radiation exposure presents another major health risk. The lack of a planetary magnetic field means that Mars receives higher levels of galactic cosmic radiation and solar particle events than Earth. Chronic radiation exposure increases cancer risk and may cause cognitive decline, cardiovascular disease, and other health effects.

Psychological health is equally important. Settlers will face long periods of isolation from Earth, confined living spaces, and constant awareness of the hostile environment. Team cohesion, communication, and support systems will be essential. The journal's scope on psychology and human factors includes isolation, confinement, and extreme environments, crew psychology and behavioral health, cognitive performance and fatigue management, human factors in habitat and systems design, team dynamics and interpersonal relations, and psychological countermeasures and support systems (Mars Settlement, 2026). Research on long-duration spaceflight and Antarctic winter-over crews provides valuable insights, but the duration and isolation of Martian settlement will be unprecedented.

4.5 Food and Agriculture

Food production on Mars is a critical component of sustainability. The journal's scope on food and agriculture includes controlled-environment agriculture, hydroponics, aeroponics, and vertical farming, Martian soil utilization and crop production, food systems design and nutrition, and microbial food production and synthetic biology (Mars Settlement, 2026). The challenge is not merely producing enough calories; it is producing nutritious, palatable, and psychologically satisfying food in a resource-constrained environment.

4.6 Robotics and Artificial Intelligence

Autonomous systems will be essential for settlement. The journal's scope on robotics and artificial intelligence includes autonomous rovers and exploration systems, AI-assisted exploration and decision support, human-robot interaction and collaboration, autonomous construction and maintenance, swarm robotics and multi-agent systems, and intelligent systems for habitat management (Mars Settlement, 2026). Robots will perform tasks that are too dangerous, too repetitive, or too precise for humans, and they will work alongside human settlers in a symbiotic relationship.

5. The Social and Governance Dimensions of Extraterrestrial Settlement

Beyond the technical challenges lie profound questions of social organization, governance, law, and ethics. These dimensions have received far less attention than engineering challenges, yet they will be equally determinative of the success and character of Martian settlement.

5.1 Governance Structures

Who will govern Mars settlements? What legal frameworks will apply? How will disputes be resolved? These questions must be addressed before settlement proceeds, as the absence of clear governance structures invites conflict, exploitation, and instability.

The Outer Space Treaty of 1967 establishes that space is the province of all mankind and prohibits national claims of sovereignty over celestial bodies. However, it does not address property rights, resource extraction, or governance of settlements. The Artemis Accords, signed by multiple nations in 2020, attempt to establish principles for lunar and Martian exploration, including transparency, interoperability, and preservation of heritage sites. But these accords are non-binding and exclude major spacefaring nations like China and Russia.

The journal's scope on law, governance, and ethics includes space law and international frameworks, planetary governance and institutional design, property rights and resource rights, planetary protection and environmental ethics, ethical frameworks for settlement, human rights and justice beyond Earth, and governance models for extraterrestrial communities (Mars Settlement, 2026). Scholars have proposed various models for Martian governance, including international consortia, corporate governance, and direct democracy (Deudney, 2020). Each model has advantages and disadvantages. International governance may be difficult to implement effectively. Corporate governance may prioritize profit over welfare. Direct democracy may be impractical for dispersed and diverse populations.

5.2 Economic Systems

The economic viability of Martian settlement remains an open question. The journal's scope on economics includes space economics and Mars settlement economics, resource economics and cost modeling, commercial space activity and markets, interplanetary supply chains and logistics, economic viability and sustainability, and investment and financial frameworks (Mars Settlement, 2026). What economic activities will generate value? Possible candidates include: scientific research, resource extraction, tourism, and intellectual property. However, the costs of transportation and infrastructure are so high that it is unclear whether any economic activity can be profitable in the near term.

Economic models for Mars settlement must address the unique characteristics of the Martian economy: high transportation costs, limited population, and dependence on Earth for many goods and services. Some scholars argue that Mars will remain economically dependent on Earth for centuries (Targowski, 2025). Others argue that the development of in-situ resources, particularly water and rare metals, could create economic value.

The legal framework for property rights and resource extraction is uncertain. The Outer Space Treaty prohibits national appropriation but does not explicitly prohibit private ownership. The Artemis Accords allow for resource extraction but do not provide a clear framework for property rights. This uncertainty creates investment risk and may hinder economic development.

5.3 Social Organization and Culture

Martian society will not be a simple replication of Earthly societies; it will be a new social formation, shaped by the unique constraints and opportunities of its environment. The journal's scope on society and culture includes Martian society and social organization, sociology of settlement and community formation, education and knowledge transmission, communication and information systems, culture, identity, and values, and generational dynamics and social continuity (Mars Settlement, 2026).

Demographics will be shaped by the challenges of transportation, health, and reproduction in a hostile environment. The physical and psychological demands of Martian life may select for certain traits, creating a distinctive population. The family structure may be altered by the challenges of pregnancy and childbirth in partial gravity, as well as by the small population size.

Education on Mars will be crucial for maintaining technical expertise and fostering a sense of identity. The physical and intellectual skills required for Martian life differ from those required on Earth, and the educational system must adapt accordingly. Cultural expression on Mars will be shaped by the unique experience of living on another world. Mars may develop its own literature, art, music, and philosophy, drawing inspiration from its distinctive landscape and society.

6. The Long-Term Vision: MARS 2050 and Beyond

The journal's scope includes a dedicated section on "MARS 2050," which encompasses futures-oriented research and scenario development, mid-century settlement visions and projections, long-term population and capacity modeling, closed ecological system requirements, governance and societal evolution, human adaptation limits and possibilities, resource self-sufficiency scenarios, and comparative futures of planetary civilization (Mars Settlement, 2026).

This forward-looking orientation distinguishes the journal and reflects the reality that Martian settlement is a project that will unfold over centuries and millennia. The decisions made today will shape the future of Martian society for generations to come. The "MARS 2050" section provides a forum for researchers to explore what a mature Martian settlement might look like, what challenges it would face, and what opportunities it would offer.

The journal's "MARS SYSTEMS" section takes an integrated systems approach to settlement, covering habitat, energy, food, water, oxygen, waste management, transportation, human systems, artificial intelligence, system-of-systems modeling and optimization, and resilience, redundancy, and sustainability (Mars Settlement, 2026). This systems perspective is essential for understanding the interdependencies that will determine the success or failure of a Martian settlement.

7. Ethical and Philosophical Dimensions of Martian Settlement

The question of Martian settlement extends beyond technical feasibility and social organization to fundamental ethical and philosophical issues. Why should we go? What is our moral responsibility to Mars and potential Martian life? What duties do we owe to future generations who will inhabit Mars?

7.1 The Positive Cosmic Redundancy Principle

Lo Sapio (2026) offers a valuable framework for evaluating the ethics of space expansion. The "Positive Cosmic Redundancy Principle" suggests that space expansion is justifiable if it reinforces, rather than diminishes, our commitment to safeguarding Earth. According to this principle, the expansion of humanity into space should not be a replacement for caring for Earth but an expression of humanity's commitment to its own long-term future.

7.2 Astroethics and Planetary Protection

The potential for microbial life on Mars introduces profound ethical questions. If life exists or existed on Mars, do we have a moral duty to protect it? How should we balance scientific exploration with preservation of pristine environments? What is the status of extraterrestrial life, and do its interests deserve moral consideration?

Recent UNESCO discussions on astroethics emphasize the need for multi-species ethics and protecting the potential for extant Martian life (Chon-Torres, 2026). These discussions challenge the anthropocentric assumption that human interests should dominate. They suggest that life on Mars, even microbial life, has intrinsic value and that human activities should be constrained to protect it.

Planetary protection protocols, designed to prevent contamination of Mars with Earth life and vice versa, are currently in place for robotic missions. However, these protocols will become more difficult to enforce when humans are present on the surface. The movement of human beings and the infrastructure required to support them inevitably carries biological contamination. The ethical frameworks for managing this contamination must be developed before humans are sent to Mars.

7.3 Duties to Future Generations

Martian settlement is a project that will unfold over centuries and millennia. The decisions made by the current generation will have profound consequences for countless future generations of Martians. This raises questions about intergenerational justice: what duties do we owe to the inhabitants of a future Mars?

The most obvious duty is to ensure that Mars is a safe and habitable environment for its inhabitants. This implies that settlement should be pursued only if it is technically feasible and that the risks of catastrophic failure are minimized. It also implies that the benefits and burdens of settlement should be fairly distributed across generations.

A more ambitious duty is to ensure that Martian society is a flourishing one, capable of providing its members with the opportunities for a good life. This implies that the social, cultural, and environmental dimensions of settlement are attended to, and that Martian society is not merely a survival outpost but a vibrant human civilization.

7.4 Avoiding the Reproduction of Earthly Injustices

There is a risk that Martian settlement will reproduce the inequalities, injustices, and conflicts that have characterized Earth's history. The colonial project, with its extractive practices, exploitation of indigenous populations, and environmental degradation, serves as a cautionary tale. The settlement of space must avoid replicating these patterns (Deudney, 2020).

The "One-Eighth Principle" articulated by Elvis and Milligan (2019) highlights the unique resource constraints of space settlement and the potential for conflict if governance is inadequate. The scarcity of resources on Mars, combined with the distance from Earth, could create conditions for exploitation and conflict. Careful governance, fair resource allocation, and inclusive participation are essential to avoid these outcomes.

The settlement of Mars also raises questions about justice within Earthly societies. The resources devoted to Mars settlement—estimated at hundreds of billions of dollars—could alternatively be used to address pressing Earthly problems such as poverty, disease, and environmental degradation. While the long-term benefits of Mars settlement may justify these expenditures, there is a moral obligation to ensure that Earthly needs are not forgotten in the pursuit of extraterrestrial ambitions.

8. The Cultural and Philosophical Significance of Multi-Planetary Existence

Perhaps the most profound aspect of Martian settlement is its meaning. What does it mean for humanity to become a multi-planetary species? How does this change our understanding of ourselves, our place in the universe, and our relationship with Earth?

8.1 A New Relationship with Earth

The settlement of Mars will transform the relationship between humanity and Earth. For the first time, Earth will not be the only human home; it will be one of multiple human homes. This could lead to a new appreciation for Earth and its uniqueness, or it could lead to a devaluation of Earth as a mere starting point.

Research on space settlement suggests that viewing Earth from space creates an "overview effect"—a cognitive shift that generates feelings of awe, interconnectedness, and environmental concern. The settlement of Mars may generalize this effect, creating a greater appreciation for the uniqueness of all planetary environments.

8.2 The Question of Identity

Who are Martians, and what does it mean to be a Martian? The residents of Mars will be shaped by their environment in ways that distinguish them from Earthlings. The physical differences—lower gravity, higher radiation, different landscapes—will create a distinctive way of life. The social and cultural evolution of Martian society may lead to the emergence of a distinct identity.

The relationship between Mars and Earth may be one of cooperation or conflict, integration or independence. The long-term trajectory of Martian society may lead to political and cultural divergence. The meaning of being human may expand to include multiple forms of human existence.

8.3 The Search for Meaning in the Cosmos

For millennia, humanity has looked to the stars with wonder and curiosity. The settlement of Mars represents the realization of a dream that has inspired countless generations. But the settlement of Mars is not simply a technological achievement; it is a project of meaning.

The question of why we should go to Mars—whether for survival, exploration, resource extraction, or existential expansion—is ultimately a question about the purpose of human existence. The Martian settlement project invites us to reflect on what we value, what we hope for, and what kind of future we want to create.

9. The Journal's Contribution: A Platform for Rigorous Dialogue

10. Conclusion: The Journey Ahead

The journey to Mars will be the greatest endeavor in human history, and it will require the full breadth of our knowledge, ingenuity, and shared humanity. It is a journey of exploration, yes, but also of creation—the creation of a new home, a new society, and a new future for humanity. It is a journey of immense technical difficulty, but also of profound ethical, cultural, and philosophical significance.

The settlement of Mars is not a foregone conclusion. It depends on our collective will, our ingenuity, and our commitment to a vision of humanity that is expansive, inclusive, and responsible. It requires us to think beyond our current constraints and to imagine a future that is worthy of our aspirations.

This journal is dedicated to that vision. We invite researchers, engineers, astrobiologists, policymakers, and scholars from all relevant fields to contribute to this vital enterprise. Together, we can build the intellectual foundations for a multi-planetary civilization that is sustainable, just, and meaningful.

The journal's motto—"From Exploration to Settlement"—captures its essential mission. It is a call to move beyond the exploratory mindset that has dominated space research for decades and to embrace the far more ambitious and consequential project of creating a permanent human presence on another world. It is a call to think not just about the next mission but about the next century, not just about survival but about flourishing, not just about Mars but about humanity's future in the cosmos.

The journey ahead is long and uncertain, but it is also filled with hope and possibility. With rigorous scholarship, interdisciplinary collaboration, and ethical reflection, we can build a future that is worthy of our aspirations.
