Governments around the world are realising the potential the space industry could be bringing into their respective economies. An exceptional amount of capital is being invested both by governments and the private sector.\par - % With commercial passenger sub-orbital launches imminent, human spaceflight will become more commonplace. The “NewSpace” arena also has projects ranging from active debris removal and artificial shooting stars missions to lunar gateway and space hotel concepts as well as human lunar and Mars missions.\par - % Space insurance has always been an enabler of new projects, providing both hull and liability coverages. Despite the market and technical challenges, space insurers will continue to support the industry going forward.\par - - - Due to Earth’s insatiable need for information and communication, the artificial satellite industry is booming. - The ability of satellites to collect signals and data extensively, even from places hard to reach, allows for a variety of functions such as providing satellite telecommunication, satisfying weather and climate monitoring, supporting satellite television (BskyB, Direct TV, SkyTV and Dish), meeting Global Positioning System (GPS) needs, and serving for military and scientific. - Since the 1980s, with the privatization of telecommunication organizations as well as the development of space laws and regulatory regimes, commercial space has begun to sprout \citep{OECD2014}. - Furthermore, SpaceX Falcon 9 delivering the SES-8 satellite into orbit marks on Dec.3th, 2013, marks the rise of the private space launch market \citep{spacex}. - Space is no longer confined to government and military agencies like NASA and its contractors but expanding rapidly via private commercial companies like SpaceX, Blue Origin, Cloud Constellation Corporation, and more. -% According to \cite{TheSpaceReport2021}, the space economy grew $176\%$ during the last 15 years, reaching $447$ billion dollars in 2020. It is worth noting that $80\%$ of the total income is contributed by the commercial space. In addition, there are more than 1,100 SmallSats launched in 2020, which is twice in average size over the same period. - According to the Satellite Industry Association (SIA), since 2014, the global space industry revenue has continued to grow, and by 2021, the total revenue of the global space industry reaches \$386 billion. - From the perspective of the composition of the global space industry, at present, the development of the global space industry is still dominated by the satellite industry. - Since 2016, the share of the global satellite industry in the space industry has exceeded 70\%. - In 2021, the national satellite industry will account for 72.3\% of the space industry. + Man-made satellites can collect extensive and valuable data which can be used in archaeology, cartography, environmental monitoring, meteorology, and reconnaissance applications. + Space is no longer confined to government and military agencies like NASA, but open to private companies since 1980s, thanks to the changes of space laws and regulatory regime \citep{OECD2014}. + On Dec.3th 2013, the SES-8 satellite was successfully delivered by a Falcon 9 launch vehicle made by SpaceX, a private company founded in 2002 shaking up the competitive satellite launch industry by offering lower cost launches than their competitors \citep{spacex}. + This successful launch significantly promotes the global space industry, the total revenue of which reaches \$386 billion by 2021, according to the Satellite Industry Association \citep{Space2022}. The commercial satellite industry put a record 1,713 commercial satellites into orbit for the fourth consecutive year, an increase of more than 40\% compared to 2020. - The SIA reported 4,852 satellites orbiting Earth by the end of 2021, an increase of 179 percent over the past five years. \citep{Space2022}. - - That means the space launch market gradually plays a pivotal part in modern societies and economic growth. - In parallel, the vigorous development of the space economy also points that the needs of operation management implanting in the space launch market are increasing \citep{Kucukcay}. - - %商业航天面临的问题 - While the successful SpaceX mission has created new enthusiasm for commercial satellite launching, there are still many risks that should not be ignored in satellite launch services, such as the responsibility of the vehicle, the indicators of the satellite, the condition of the launch activity so on. - In addition, many private investors are hesitant about investing in space businesses because of the costly infrastructure and extended timelines. - From the perspective of private companies, once the launch fails, the loss for both satellite operator and launch servicer is enormous. While governmental and military satellites are usually self-insured, commercial satellite operators often require insurance to be in place.\par + Behind such vigorous development, the launch failure risk can not ignored by the companies in satellite launch supply chain (SLSC). + Once the launch fails, the loss for both vehicle manufacturer and satellite operator is enormous. + To hedge this risk, there are three solutions in practice. - % 解决商业航天风险的一个途径是购买航天保险。 - In order to hedge launch risks, space insurance emerged. Insurance companies like Global Aerospace have been providing insurance for space initiatives since the first commercial satellites and launch vehicles required financial support to cover their risk. - New concepts and technologies such as prominent constellations of satellites have distinctive risk profiles requiring unique coverages. - According to the satellite launch project process, space insurance is roughly divided into four types of coverage which reflect the various phases of most satellite projects - pre-launch insurance \footnote{ Pre-launch insurance covers damage to a satellite or launch vehicle during the construction, transportation, and processing phases prior to launch.}, - launch insurance \footnote{ Launch insurance covers losses of a satellite occurring during the launch phase of a project. It insures against complete launch failures as well as the failure of a launch vehicle to place a satellite in the proper orbit.}, - in-orbit insurance \footnote{In-orbit policies insure satellites for in-orbit technical problems and damages once a satellite has been placed by a launch vehicle in its proper orbit.}, - and launch plus life insurance \footnote{Third-party liability and government property insurances protect launch service providers and their customers in the event of public injury or government property damage, respectively, caused by launch or mission failure.}. - The launch insurance is usually the most widely focused \citep{Suchodolski2018} because the launch is the riskiest part of any space activity, and the damage is often catastrophic. \citep{Gould2000, Kunstadter2020}. \par - Concerning about the high premium, some governments have introduced policies to subsidize the commercial industry. - For example, Beijing Bureau of Economy and Information Technology has implemented an subsidy about commercial space launch insurance to support commercial space enterprises to engage in the production and manufacture of vehicles and satellites in Beijing, and encourage commercial space enterprises to establish headquarters, sales and operation in Beijing. - In addition, Russian and Japan also provide government indemnification for the loss of satellite launching activity. - Besides, the UK government invested in launch sites to provide new satellite launch services mentioned in its industrial strategy white paper. - The Unites States not only provided subsidy for launch liability insurance but also awarded the commercial companies directly. - - % 除了在金融方面补偿风险外，还可以通过提升技术的方式降低发射失败率。 - In addition to compensating for risk financially, reducing the launch failure rate on the technical side is also an available way for commercial space companies. - While commercialized space projects have braved all the challenges, they are still involved in conventional economic models that may hamper their growth and success. Luckily, blockchain technology supports building smart contracts and tracking data, considered a disruptive technology that facilitates data flow. - In the real world, companies are emerging to implementing blockchain technology specifically for space launches, such as SpaceChain, IBM and Cloud Constellation Corporation. - The blockchain is used to deal with the above complexities such as contracts, order tracking, parts assembly, shipments, design and test documents, test results data, near real-time data, workflows for approvals, auditing, launch, and control, which make the project more visible, responsive and mitigate costly interruptions during the launch, in other words, it increases the probability of successful launch \citep{Zheng2021}. - Here are the main features in details of blockchain about supporting space launch:\par + First, space insurance emerged. + Insurance companies like \textit{Global Aerospace} have been providing different space insurance services, which can be roughly divided into four types according to satellite project phases: pre-launch insurance\footnote{ Pre-launch insurance covers damage to a satellite or launch vehicle during the construction, transportation, and processing phases prior to launch.}, launch insurance\footnote{Launch insurance covers losses of a satellite occurring during the launch phase of a project.

We review them as follows and list the differences between our work and existing literature at the end of each subsection. + Our paper is closely related to four research streams: supply chain insurance, space supply chain management, blockchain, and government subsidies. + + \subsection{Supply chain insurance} + Supply chain insurance is a sub-stream of supply chain finance which is extensively studied in today's FinTech era \citep{Zhao2015,Xu2018,Wang2021b}. + At an affordable expense, supply chain insurance hedges against the risks caused by internal (e.g., the interruption of funds, and the disruption of logistic) or external (e.g., extreme weather, COVID-19 pandemic) factors \citep{Sodhi2012a, Heckmann2015}. + + According to the type of risks @@@ (what kind of types?), the literature on supply chain insurance can be divided into two categories. + (1) Combining insurance contracts with supply chain contracts. + For example, \citet{Lin2010} compared insurance contract with revenue sharing contract according to different agents' risk aversion based on the news-vendor model. + Besides, \citet{Wang2021} also discussed which contract is better for supply chain partners between the advanced payment contract, penalty contract, and time insurance contract in the express delivery supply chain. + (2) Trade-off between costly commercial insurance and substantial economic losses. + For example, \cite{LodreeJr2008} designed an insurance policy framework to quantify the risks and benefits. \cite{Yu2021} considered the interrupt probability of the supply chain, and illustrate that business interruption insurance increases the profit of each participant. + \cite{Brusset2018} constructed a weather index, so that entrepreneurial risk can be transferred to other risk-takers through insurance or options contracts. + + \subsection{Space supply chain management} + Space supply chain management can be viewed as a part of space operations. + In the early stage, this research stream generally focused on space logistics, e.g., developing an integrated space supply chain management framework \citep{MIT}. + \cite{Taylor2006} aimed to optimize delivery operation @@@ use what kind of method? + According to the research goal, the literature on space supply chain management can also be divided into two categories. + (1) Optimizing the operating system to improve the efficiency. + \cite{Galluzzi2006} regarded supply chain management as a critical piece of framework in the aerospace industry, and they elaborated the pattern operation in this area. + \cite{Taylor2006} also designed and evaluated the operating system in the space supply chain, but they primarily engaged in optimizing delivery operation, which sustains the exploration initiative. + Moreover, \cite{Gralla2006} gave a comprehensive model and simulation of the supply chain management implemented in the aerospace industry, which is low-volume and schedule-driven compared to the high-volume and market demand-driven SCM in the commercial sector.\par + (2) analyzing the business problem in supply chain management. The research on this topic is relatively few. + \cite{Wooten2018} examined the space industry's operation management, which involves manufacturing operations, supply chain management, and sustainable operations. Besides, they also outlined the challenges and essential questions related to stakeholders. + \cite{Raghunath2021} discussed the challenges that commercial space operation faces from a business perspective. + Furthermore, \cite{Guo2021} comprehensively analyzed the global aerospace industry's current situation and future development from the upstream supply chain, midstream production chain, and downstream application chain. + In addition, \cite{Donelli2021} considered the profitability and efficiency during the aircraft manufacturing and supply chain. The paper proposed a model-based approach to optimal the multiple-choice. + Furthermore, \cite{Dewicki} also based on operational management analyze the business model in commercial space. \par + As review literature, most papers target SCM in space give the mathematical model from optimizing logistics, even the system flow.
