<description>Developing an Anti-Colonial Practice: Moving from Conversation to Structural and Institutional Change within the Space Community
Harvey, Alvin Donel; Tavares, Frank; Reynolds-Cuéllar, Pedro; Lombardo, Seamus
Navigating questions around the future of space exploration will require cross-cultural conversations and a recognition that all peoples and cultures on Earth have a stake in how we engage in being Off-Earth. Currently, Western and Euro-centric systems dominate the way the space community engages in space exploration, technology development, and science in space. In 2021, the Space Enabled Research Group at the MIT Media Lab hosted a series of online webinars and a workshop on Indigenous Anti-Colonial Views on Human Activity in Space to discuss incorporating and centering Indigenous epistemologies and people in the space community and how to resist and replace colonial structures and tendencies. Post seminars and a workshop a central question remains: how do these conversations turn into long-standing relationships that have a concrete impact on decision-making and technical practices related to space? Ultimately, there is tension when engaging in conversations around anti-colonial thought while operating within institutions that are intertwined with the very systems being critiqued. This tension pervades multiple facets of operating within these structures, affecting the conceptualization, planning, facilitation, and reflection of conversations around Indigenous and anti-colonial views on human activity in space. By critically reflecting on the experience of formulating and facilitating the webinar series and workshop, using data collected from a survey of participants after the series, and learning from continued collaborations with Indigenous and anti-colonial scholars, this paper reflects on the presence of tension, and on how to make it a productive starting point for institutional and structural change within the space community.

<description>Centering Indigenous Voices and Resisting Colonialism In Space Exploration: An Overview Of The Ongoing Webinar Series By Space Enabled
Tavares, Frank; Harvey, Alvin Donel; Lombardo, Seamus; Reynolds-Cuéllar, Pedro; Newman, Dava; Wood, Danielle
Indigenous perspectives and an anticolonial framework are essential to an equitable and genuinely sustainable future in space. Often imagined as an extension of manifest destiny and western expansion, space exploration requires a reframing if it is to achieve its potential to be a catalyst for ways of living and forming community that do not reproduce the same destructive systems of western capitalism. By understanding the ways in which past and present systems of coloniality intersect with the space sector and centering the experiences of Indigenous peoples in space exploration, a new way of conceptualizing space exploration can potentially emerge. Centering these issues highlights both near-term policy questions around lunar exploration as well as longer term questions about how to envision interactions with potential extraterrestrial life and sustained human communities on other worlds. To explore these ideas, the authors organized a series of webinars throughout 2021 hosted by the Space Enabled Research Group at the MIT Media Lab, with more events to come. The webinars address topics such as: 1) Indigenous perspectives on space exploration and the impact of a colonial mindset on the field; 2) near-term policy questions for lunar exploration; and 3) the role of astrobiology and opportunities for an anticolonial perspective to open up new ways to imagine potential futures in space. In this paper, the organizers of the webinar series present some of the key outcomes from the webinar series and the discussions it generated, and offer lessons learned from these concepts for the space community.

<description>Centrifugal Casting of Paraffin and Beeswax for Hybrid Rockets
Stober, Keith J; Sanchez, Alana; Wanyiri, Juliet; Jiwani, Suzanna; Wood, Danielle Renee
© 2020, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved. A high-level research framework is presented which seeks to navigate the barriers associated with reusing wax phase change material onboard a satellite as a hybrid rocket fuel for de-orbit or other in-space propulsion needs, while also conducting fundamental studies of the fluid mechanics and heat transfer phenomena which drive the cooling and solidification of wax within a horizontal rotating cylinder in various gravitational and thermal environments. A detailed review of past work in the area of beeswax fuel for hybrid chemical propulsion is reported and served to motivate consideration of this fuel for centrifugal casting efforts, due to previously reported values of regression rate comparable to that of paraffin wax. The production process of beeswax fuel from beekeeping detritus was perfected and documented. Analysis of the shrinkage of beeswax and the neat Candlewic FR5560 paraffin wax used herein determined a volume shrinkage percentage during liquid to solid phase transition of 18.7 ± 0.62 and 13.3 ± 0.22%, respectively. An image analysis routine was developed in order to automate the process of determining the instantaneous solidification rate for each one-second timestep through the centrifugal casting process of paraffin and beeswax fuel grain sizes common for small-scale hybrid rockets. Beeswax completed solidification in 22% less time than paraffin under identical conditions but exhibited more coning of resulting solid wax. Calculated time-and space-averaged solidification rates for paraffin and beeswax were 0.017 and 0.028 mm/s, respectively, within a 50.8 mm inner diameter, 57.15 mm outer diameter, and 254 mm length polycarbonate tube. Careful analysis, however, shows that instantaneous solidification rate increases very slightly but steadily over time for both paraffin and beeswax, though the rate increase is greater for beeswax. The image analysis routine was most effective when applied to the beeswax solidification process as compared to that of paraffin, as the solid/liquid interface is considerably more salient in beeswax due to a distinct color change upon solidification. Dye will be used with paraffin casting in the future with the goal of improving solid/liquid phase contrast.

<description>Vida Decision Support System: An International, Collaborative Project for COVID-19 Management with Integrated Modeling
Reid, Jack B.; Lombardo, Seamus; Turner, Katlyn; Zheng, Maggie; Wood, Danielle R.
The Vida Decision Support System (Vida) is an application of the Environment-Vulnerability-&#13;
Decision-Technology (EVDT) integrated modeling framework specifically aimed at COVID-19 impact&#13;
and response analysis. The development of Vida has been an international collaboration involving&#13;
multidisciplinary teams of academics, government officials (including public health, economics,&#13;
environmental, and demographic data collection officials), and others from six states: Angola, Brazil,&#13;
Chile, Indonesia, Mexico, and the United States. These collaborators have been involved with&#13;
the identification of decision support needs, the surfacing and creation of relevant data products,&#13;
and the evaluation of prototypes, with the vision of creating an openly available online platform&#13;
that integrates earth observation instruments (Landsat, VIIRs, Planet Lab’s PlanetScope, NASA’s&#13;
Socioeconomic Data and Applications Center, etc.) with in-situ data sources (COVID-19 case data,&#13;
local demographic data, policy histories, mobile device-based mobility indices, etc.). Vida both&#13;
visualizes historical data of relevance to decision-makers and simulates possible future scenarios.&#13;
The modeling techniques used include system dynamics for public health, EO-based change detection&#13;
and machine learning for environmental analysis, and discrete-event simulation of policy changes and&#13;
impacts. In addition to the direct object of this collaboration (the development of Vida), collaborators&#13;
have also benefited from sharing individual COVID-19-related insights with the network and from&#13;
considering COVID-19 response in a more integrated fashion. This work outlines the Vida Decision&#13;
Support System concept and the EVDT framework on which it is based. The international team is&#13;
using Vida to evaluate the outcomes in several large cities regarding COVID cases, environmental&#13;
changes, economic changes and policy decisions. It provides an overview of the overlapping and&#13;
diverging needs and data sources of each of the collaborating teams, as well as how each of those&#13;
teams have contributed to the development of Vida. The current state of the Vida prototypes and plans&#13;
for future development will be presented. Additionally, this work will discuss the lessons learned&#13;
from this development process and their relevance to other integrated applications.

<description>Understanding Socio-Technical Issues Affecting the Current Microgravity Research Marketplace
Joseph, Christine; Wood, Danielle
For decades, the International Space Station (ISS) has operated as a bastion of international cooperation and a unique testbed for microgravity research. Beyond enabling insights into human physiology in space, the ISS has served as a microgravity platform for numerous science experiments. In recent years, private industry has also been affiliating with NASA and international partners to offer transportation, logistics management, and payload demands. The Center for the Advancement of Science in Space (CASIS), which manages the ISS U.S. National Laboratory, has developed a diverse portfolio of private, public, international, and outreach projects. As the costs of flying projects to the ISS decrease, the barriers limiting non-traditional partners from accessing the ISS as a platform also decrease. However, the ISS in its current form cannot be sustained forever. As NASA looks towards commercialization of the low Earth orbit (LEO) space and the development of a cislunar station, concrete plans for shifting the public-private relationship of the ISS are unclear. With the consistent need to continue microgravity research - from governments and private industry - understanding the socio-technical and policy issues that affect the marketplace for future microgravity platforms is essential to maintaining an accessible and sustainable space economy. How will the U.S. and other governments design public-private partnerships to pursue economic and social goals in the LEO microgravity ecosystem? What governance structures will influence who is eligible to operate platforms for activities including tourism, research, manufacturing and outreach? How will international collaboration occur in the future LEO microgravity ecosystem? This paper presents a review of the current microgravity research ecosystem with a focus on potential future marketplace dynamics.

<description>Using earth observation data to inform community management of invasive plants and traditional fishing practices on Lake Nokoué in Benin
Ovienmhada, Ufuoma; Fatoyinbo, T; Lagomasino, D; Mouftaou, F; Ashcroft, E; Lombardo, Seamus(Seamus Joseph Holt); Wood, Danielle
The research explores an Earth Observation (EO) application with the enterprise Green Keeper Africa (GKA) based in Cotonou, Benin, that addresses the management of an invasive plant species that threatens economic activities such as fishing, transportation and irrigation. GKA pays local community members to harvest the water hyacinth and transform it into a product that absorbs oil-based waste. The EO application is an online observatory and decision support tool that utilizes satellite, aerial and ground data to map the location of the water hyacinth and a fish farming practice known as “acadja” over time, providing valuable information for government, private and public users. The acadja analysis is relevant due to the adverse effects on water quality that the practice results in. This paper is a follow up on the work presented in the 2019 contribution to IAC session B1.5 by the authors. New research in this paper includes (i) improved and validated remote sensing algorithms for monitoring water hyacinth extent, (ii) trend analysis and forecasting of water hyacinth growth with other environmental data sets, (iii) improved and validated remote sensing algorithms for identifying and quantifying acadja and (iv) analysis of water quality parameters describing the coastal ecosystem.

<description>Space sustainability rating: Designing a composite indicator to incentivise satellite operators to pursue long-term sustainability of the space environment
Rathnasabapathy, Minoo; Wood, Danielle; Letizia, F; Lemmens, S; Jah, M; Schiller, A; Christensen, C; Potter, S; Khlystov, N; Soshkin, M; Acuff, K; Lifson, Miles(Miles Thelonius Keylor); Steindl, Riley M.
The Space Sustainability Rating (SSR) was first conceptualised within the World Economic Forum Global Future Council on Space Technologies, and is being designed by an international and transdisciplinary consortia including the World Economic Forum, Space Enabled Research Group at Massachusetts Institute of Technology (MIT) Media Lab, European Space Agency, University of Texas at Austin, and Bryce Space and Technology. With the increasing awareness of the rapidly growing number of objects in space, the implementation of a rating system, such as the SSR, provides an innovative way to address the orbital challenge by incentivising industry to design missions compatible with sustainable and responsible operations, and operate missions considering potential harm to the orbital environment and impact on other operators in addition to mission objectives and service quality. This paper builds upon the SSR concept introduced at the IAC in 2019, and provides in-depth description into the methodology used to design the SSR, based on successful rating systems in other industries such as LEED (green building energy and environmental design). This method seeks to provide a practice tool that governments, satellite operators and insurers can reference. The process also seeks to build capability among emerging space actors as they seek to understand how to design responsible space missions. The SSR is a composite indicator that is a function of the Space Traffic Footprint, measured through a mission index and compared to the so-called Environment Capacity and other measures of the responsibility shown by operator actions. The components of the SSR take into account mission aspects including on-orbit fragmentation risk, collision avoidance capabilities, detectability, identification, trackability, data sharing, on-orbit servicing, collision avoidance, debris mitigation, and adoption of international standards. The paper further explores key questions including; (i) what factors are most important to influence whether an operator seeks to reduce the potential for debris creation, (ii) how can the SSR can contribute to existing mechanisms (eg. UN Long-term Sustainability Guidelines, IADC) in supporting long-term space sustainability, and (iii) how can the SSR educate policy makers regarding manufacturers' and operators' motivations in choosing specific criteria and certifications in designing their mission to achieve a high rating or improve their existing rating.

<description>Exploratory methods and techniques for space technology development and space mission concept development
B. De La Torre, Lizbeth(Barrios De La Torre); Wood, Danielle
This paper hopes to fill a gap in literature by framing the current state of exploratory design methods and techniques within space mission development and laying the groundwork to begin utilizing a wider variety of these methods and accompanying techniques. The purpose of this paper is to review the ways in which design methods and techniques used in other fields may be used in support of the space mission concept development process and space technology development. Designers are almost synonymous with the consumer product, automotive and entertainment industries. Fields such as Product Design, Transportation Design and Entertainment emphasize finding solutions to problems using exploratory design methods and techniques. Often, they are leaders in their organizations. However, there is not a direct appreciation or understanding of how to utilize these methods and techniques within aerospace. These methods have been shown to support mission concept development, however may also directly support technology development, as is seen in the consumer product industry. Evidence shows that these methods have sporadically been utilized by NASA for habitat design, software development and astronaut wearables. This paper explores opportunities within the space mission concept development process where these techniques are currently used and develops a design library of methods and techniques used outside of Aerospace that may be supportive of technology development. The current Pre-Phase A concept development process is mapped along with exploratory design methods used in other industries. Design Thinking is a heuristic problem solving method that can be applied to many fields. Human Centered Design and User Centered Design have been utilized for architecture and software development; these same tools could also be used to help inform the design of long term human habitation system on planetary surfaces. The Imagineering process is instrumental in theme park development; this paper argues it should also inform design of robotic science missions such as Mars Sciences. Science Fiction Thinking is a method of extrapolating future technology. How can this type of thinking inform the design of systems that aim to detect life in locations such as the liquid oceans on Europa and Titan? Techniques that are instrumental throughout these methods, such as storyboarding, sketching and prototyping are also defined. Interviews with employees within aerospace, consumer products and entertainment may shed light on opportunities and barriers to utilizing these techniques.

<description>Leveraging microgravity to investigate earth- And space-based centrifugal casting of wax
Stober, Keith J; Sanchez, Alana; Apodaca Moreno, Maria Regina.; Ngetich, Gladys; Erkel, Daniel; Wanyiri, Juliet; Wood, Danielle
A multi-year research effort aimed at increasing understanding of the centrifugal casting process of wax fuels for hybrid chemical propulsion in multiple thermal and gravitational environments is described. As both radiative and convective heat transfer drive the casting process, the suborbital and orbital microgravity environments are critical to disentangling these contributions to heat transfer away from the fuel. The experimental effort comprises testing on multiple platforms, including the ambient atmosphere of the laboratory, as well as various mobile microgravity platforms. Testing onboard reduced-gravity aircraft facilitates increased understanding of how these types of fluids perform in the microgravity environment, while a suborbital spaceflight and orbital platform under standard atmosphere allow for longer-term observation of natural convection sans buoyancy. An orbital platform subjected to the space environment facilitates understanding of the contribution of radiation to the heat transfer away from the liquid fuel. Each progressive testing environment requires updates to the experimental setup in order to accommodate respective physical and electrical constraints which are described in detail herein. An image analysis routine was developed in order to automate post-processing and determine the solidification front speed for each test. A rotation rate actuation routine is in development which aims to improve the accuracy of the centrifuge control system by leveraging electromagnetic sensing and feeding back rotation rate measurements to the motor driver. Preliminary modeling work was conducted which aims to elucidate the fundamental physics of the centrifugal casting problem; specifically, the impact of rotation rate, material properties, and environmental conditions on the heat transfer and fluid mechanics which constitute the larger casting problem. Both paraffin wax - a solid fuel with two decades of heritage - and the more novel beeswax are considered in this study.

<description>Interactive Model for Assessing Mangrove Health, Ecosystem Services, Policy Consequences, and Satellite Design in Rio de Janeiro Using Earth Observation Data
Reida, Jack B.; Wood, Danielle
There is an increasing need for tools to translate Earth Observation (EO) data into societally rele-&#13;
vant metrics to inform human decision-making. To address this need, we present a multi-disciplinary,&#13;
interactive modeling framework to advance ecological forecasting and policymaking using EO data. This&#13;
framework will integrate four model components into one tool: Earth Science, Social Impact, Human&#13;
Behavior and Satellite Design. The capabilities provided by this framework will improve the management&#13;
of EO and socioeconomic data in a format usable by non-experts, while harnessing cloud computing,&#13;
machine learning, economic analysis, complex systems modeling, and model-based systems engineering.&#13;
This paper presents a prototype that demonstrates the viability of the framework via a case study:&#13;
the mangrove forests in the Guaratiba area of Rio de Janeiro. These mangroves are vulnerable due to&#13;
urbanization and rising sea levels. They provide a variety of ecosystem services, including serving as&#13;
a mechanism for carbon sequestration, supporting subsistence  shing, preventing coastal erosion, and&#13;
attracting an ecotourism industry.&#13;
The case study of mangrove and community health in Rio de Janeiro demonstrates all four model&#13;
components. The Earth Science Model builds upon work by NASA biospheric scientists to use EO data,&#13;
cloud computing and machine learning to track mangrove extent, health, and vulnerability over time for a&#13;
600 km2 area, as well as work by the Espa co research group at the Universidade Federal do Rio de Janeiro&#13;
on the local mangrove ecosystem. To create the Human Decision Making model, we have partnered with&#13;
Instituto Pereira Passos (the data science o ce of the Rio de Janeiro municipal government) to understand&#13;
the policy history and socioeconomic factors. To build the Social Impact model, we are collaborating with&#13;
ecosystem services economists to explain how policies impact mangrove health and how mangroves impact&#13;
socioeconomic wellbeing. The Satellite Design Model accounts for the types of data collection used by&#13;
policy makers since 1985.&#13;
Through such collaborations, we are able to build an integrated, interactive model that policymakers&#13;
can use to assess mangrove health, ecosystem services value, and policy consequences. The model helps&#13;
answer such questions as: (a) What is the state of the mangroves over time? (b) How are human&#13;
communities impacting the mangroves? (c) what is the value of the mangrove ecosystem services to&#13;
human communities? and (d) what policies can improve human and mangrove outcomes? This case&#13;
study is demonstrative of the viability of a similar approach for ecosystems around the world.

<description>Combining Social, Environmental and Design Models to Support the Sustainable Development Goals
Reid, Jack Burnett; Zeng, Cynthia; Wood, Danielle Renee
There are benefits to be gained from combining the strengths of modeling frameworks that capture social, environ- mental and design-based considerations. Many of the impor- tant challenges of the next decade lie at the intersection of the natural environment, human decision making and the design of space technology to inform decision making. There are 17 Sustainable Development Goals outlined by the United Nations through 2030. Several of these Sustainable Development Goals can be addressed by asking: 1) What is happening in the natural environment?  2) How will humans be impacted by what is happening in the natural environment? 3) What decisions are humans making in response to environmental factors and why? and 4) What technology system can be designed to provide high quality information that supports human decision making? The answers to these questions are often interrelated in complex ways; thus it is helpful to use a framework from complex systems to integrate these questions. Within the list of Sustainable De- velopment Goals, several fit the three questions above, including #2 Zero Hunger, #6 Clean Water and Sanitation, #13 Climate Action, #14 Life Below Water, and #15 Life on Land. This paper presents a research agenda to apply environmental modeling, complex systems modeling, and model-based systems engineering to inform the design of space systems in support of the Sustainable Development Goals.  This work builds on previous research in the following areas: 1) physics-based en- vironmental modeling; 2) complex systems modeling to simu- late human decision making using agent-based models; and 3) model based systems engineering to inform the architecture of satellites or space-enabled data systems.  This paper presents a review of the state of the art, shows examples of how these methods have been combined to inform space system design and presents a future research agenda.  As an example, the paper discusses a project related to Sustainable Development Goal #15 to design an earth observation system using space- based and ground-based data collection regarding an invasive plant species in Benin, West Africa. In this example, insights are needed regarding natural variables (i.e. salinity, temperature and turbidity of local waterways), social variables (i.e. economic impact of the invasive plant on local communities), and design variables (i.e.  the technical performance of existing imagery satellites and in-situ sensor networks).

<description>Linking Historical Roots and Current Methodologies of Engineering Systems
Santen, Nidhi R.; Wood, Danielle
This paper reviews the historical context and present impact of two sets of literature: the work of Joseph Schumpeter and the field of Strategy Development. Schumpeter’s theories about the impact of technology or innovation on the economy are an important input into modern Engineering Systems (ES) thinking. Meanwhile, Strategy Development is an active contemporary methodology that is relevant to Engineering Systems. Both Schumpeter and the scholars in Strategy Development are concerned with how firms perform, but Schumpeter's approach is descriptive while Strategy Development is prescriptive.&#13;
The approach in this paper is as follows. It first introduces the theories of Schumpeter on innovation and the major ideas within Strategy Development. Next, two historical reviews are presented. One review looks forward to find the impact that Schumpeter has had on modern fields; the second review looks backward to understand the roots of Strategy Development. These historical reviews are initially done independently. The final section asks whether there are direct historical links between Schumpeter and the scholars or ideas of Strategy Development. The major result of this investigation is that Schumpeter’s influence is widespread as are the roots of Strategy Development. The results also show that the writing of Schumpeter is related to Strategy literature because many of Schumpeter’s ideas have become foundational realities for Strategy Development. Meanwhile, this connection is just one of many for each field, and the link between Schumpeter and Strategy Development does not appear to be the most important.
