The HRP helps enable exploration spaceflight through a focused program of research that leads to the development and delivery of solutions to protect human health and performance during and after these missions. This research is conducted primarily in ground analogs of the spaceflight environment and on the International Space Station (ISS). Over the last 3 years, NASA has undergone transformative changes with the flight of Artemis I, the formation of the Commercial Low Earth Orbit Destinations Program, commercial flights to the ISS, and collaboration with new international partners participating in human spaceflight. The HRP has embraced these new opportunities and is collaborating on all these fronts to collect biomedical research data. Artemis I marked the arrival of NASA's new human spaceflight exploration missions. NASA established the Moon to Mars Program Office to design a roadmap for the exploration of the lunar surface and the journey beyond to Mars. The HRP has a critical role in conducting research and delivering technologies that will lead to solutions that protect human health and performance, and is working closely with the Moon to Mars Office to ensure these deliverables are ready in time to support their strategy. The HRP is also developing the partnership strategies required to support these deliverables. Commercial space flights, both free flyer and suborbital missions and private astronaut missions to the ISS, are providing broader opportunities and more subjects to characterize spaceflight-induced changes to the human system and to test countermeasures. To better use these opportunities to achieve its mission, the HRP has been working to understand the commercial spaceflight companies’ needs and then partnering with them on aspects of mutual interest. In addition, the HRP continues to engage in long-standing relationships with its international partners through the International Space Life Sciences Working Group and other joint international groups. The HRP is interested in sharing its knowledge and collaborating on projects of mutual interest with new countries that are developing capabilities for human spaceflight. The next 10 years will shape how humanity partners on exploration missions to Mars, and the HRP is committed to enabling and developing collaborative strategies with commercial and international partners to keep humans safe and productive as they explore longer and further into space.</div></div>","PeriodicalId":37283,"journal":{"name":"Journal of Space Safety Engineering","volume":"12 1","pages":"Pages 47-52"},"PeriodicalIF":1.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the associated workload, COLA operations should already be considered in the early planning phases of space missions. The Mission Analysis Software (MAS) is a web-based application developed within the ESA-funded CASCADE (Collision avoidance, satellite coordination assessment demonstration environment) project by OKAPI:Orbits and TU Darmstadt for this purpose. The software follows a data-driven approach to offer satellite operators, mission designers, service providers, agencies, and authorities two services: conjunction assessment and rule analysis. The conjunction assessment provides an estimation of the number and type of conjunctions to be expected on the targeted orbit and identifies frequently conjuncting parties for the current population of active satellites as well as for conceivable future scenarios. The rule analysis follows a rule-based approach to coordinate COLA between individual operators, allowing users to build custom hierarchical rule sets from pre-defined rule building blocks to achieve a desired split of effort between the conjunction parties. The MAS enables the assessment of the operational consequences for a chosen rule set, empowering users to reach bilateral agreements with identified frequently conjuncting parties to determine the obligation to take evasive measures for future conjunctions. The approach of the MAS allows for the pre-emptive reduction of the expected number of conjunctions enabling operators to optimize orbit parameters within their mission constraints as well as the automatization of COLA coordination during operations. Through this, the MAS optimizes propellant needs, mission time, and required workforce associated with COLA for space missions.</div><div>This paper presents the MAS, showcasing the key features and use cases that have been developed closely with stakeholders and the European Space Agency.

Over the past decade, the number of spacefaring nations has increased, as evidenced by the number of satellites launched by emerging space nations and by an increase in the number of applications for United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) membership from emerging member states. More recently, there has been an increase in emerging space nations stating their commitment to join the COPUOS Long-term Sustainability (LTS) 2.0 Working Group, as well as nations who have opted to join as signatories to initiatives such as “Net Zero Space” (e.g., Azercosmos, EgSA, GISTDA), and the Artemis Accords (e.g., Nigeria, Rwanda, and Angola). These initiatives share a common goal of promoting the sustainable and responsible use of space to ensure the long-term sustainability of space activities, including: 1) the recognition of the need for sustainable practices; 2) the importance of promoting cooperation in long-term sustainability between all nations; 3) the support of international guidelines and best practices; and 4) the recognition of the increasing role and contribution of emerging space nations.</div><div>Given the rapid diversification of the space sector, and in accordance with Part C International Cooperation, Capacity-Building and Awareness of the 2019 COPUOS Long Term Sustainability guidelines, many emerging nations continue to face challenges in implementing space debris mitigation and removal measures. The aim of this paper is threefold: 1) showcase examples of emerging space nations who are actively supporting the sustained use of space at a national, regional, and international level, which includes complying with existing binding requirements concerning space debris within national laws; 2) discuss how the Space Sustainability Rating (SSR) provides opportunities for emerging space nations to progress in their efforts to participate in seeking space sustainability; and 3) provide an analysis using the SSR for several missions launched by emerging space nations including recommended steps for increased sustainability in both the design phase and during operations. The study aims to identify potential challenges and opportunities in the adoption of the SSR by emerging space nations, and dispel the perception that sustainable design, operations, and implementation of the LTS guidelines is a barrier for emerging space nations.

The fast-track development of technology and the enthusiasm to explore and exploit space resources for various benefits have also led to the development of factors that can jeopardize ongoing and future activities in outer space. On the one hand, these developments contribute to exploring new horizons of outer space but simultaneously pose significant threats to the sustainability of a conducive environment where various stakeholders can pursue their interests. Multiple initiatives have been taken at the national and international levels to address this issue; however, much more still needs to be done collectively. Since governments are the primary stakeholders and entirely responsible for space activities in terms of international law, individual efforts by governments would take longer to implement measures that can contribute to the long-term sustainability of outer space. Therefore, the role of global and regional organizations in the area has certainly become more critical. International cooperation drives the policy objectives and strategy to advance a mechanism that collectively contributes to outer space's safety and security. The regional agencies provide more significant opportunities to leverage the expertise, investments, and resources together to develop such programs. It helps to adopt multiple ways to formalize relationships that can lead to pursuing specific activities and initiatives such as joint statements, signing cooperative agreements, exchanging data, pooling financial resources, and exchanging know-how. This paper emphasizes regional cooperation schemes and identifies the possible legal tools for regional cooperation to support a safe, secure, and sustainable environment for space activities. The paper focuses on the Asia-Pacific region as a case study. It covers an analysis of the regional organizations, particularly the Asia-Pacific Space Cooperation Organization (APSCO) initiatives as the formal multilateral inter-governmental organization and the Asia-Pacific Regional Space Agency Forum (APRSAF) as a flexible and informal regional mechanism.
