Indian Space Program operates the world's largest constellation of civil remote-sensing satellites through its Indian Remote Sensing (IRS) satellites system. Since the founding of the nation's space program in 1969 with the establishment of the Indian Space Research Organization (ISRO), Earth Observation through satellites has been a core objective of the Indian Space Program harnessing the space technology for national development. The IRS system supports the Indian national economy in the areas of agriculture, water resources, forestry, ecology, geology, watersheds, marine fisheries and coastal management, and advanced research in Earth Sciences. The meteorological payloads of the Indian National Satellites (INSAT) system provide for weather and natural disaster management support. The IRS satellites system began in 1988 with the launch of IRS-1A satellite. The IRS series of satellites are designed and built by the ISRO Satellite Center based in Bengaluru while the ISRO Space Application Center in Ahmedabad fabricates the remote sensing payloads and cameras. The National Remote Sensing Center (NRSC) based in Hyderabad is responsible for acquisition, processing and supply of data to the various national programs that utilize the remote-sensing data for optimal use of country's national resources and water management. The National Natural Resources Management System (NNRMS), an autonomous organization under the aegis of the Indian Department of Space oversees interagency coordination among the various national departments that utilize the EO data and addresses underutilization and inadequacies in regional and district level ground facilities. This paper presents a Stakeholder Value Network (SVN), a multi-relation model to analyze the Indian Earth Observation system providing key insights on one of the world's largest space based Earth Observation program, as well as the value-added roles of each stakeholder within the network.

The European Space Agency (ESA) in May 2012 selected the JUICE (JUpiter ICy moons Explorer) mission as the first cornerstone large (L-class) mission within the Cosmic Vision Program 2015-25. The primary scientific objectives of the JUICE Mission carrying onboard the spacecraft ten state-of-the-art instruments are (1) Explore the habitable zone of the Galilean moons, Ganymede, Europa and Callisto and (2) Explore the Jupiter system as an archetype for gas giants. The JUICE Orbiter Mission will provide a comprehensive investigation of the icy shell, subsurface ocean and deep interior of the Solar System's largest moon Ganymede. JUICE spacecraft is based on a structure featuring a cone on which a central cylinder is mounted that hosts two propellant tanks, six shear walls and four lighten external walls. The complex trajectory of the eleven-year JUICE mission presents design challenges in radiation environment, power availability, propulsion, thermal aspects and navigation and autonomy. The Design Value Mapping (DVM) method provides a means to assess the design concepts ability to fulfill stakeholder needs, allowing decision makers to focus on key utility drivers and to identify value expectations that are potentially difficult to drive. The Multi-Attribute Tradespace Exploration (MATE), developed at MIT combines two techniques used in complex technical design and decision making: Multi-Attribute Utility Theory (MAUT) and Tradespace Exploration (TSE). This paper presents Tradespace Analysis for Spacecraft Technical Evaluation (TASTE) of ESA's JUpiter ICy moons Explorer (JUICE) through value-driven design, tradespace exploration model and visualization. An Epoch-Era Analysis (EEA) that provides a dynamic perspective of the JUICE Mission to enable evaluation of value robustness across time periods such as interplanetary cruise, scientific exploration of the Jovian system with changing contexts and value expectations is also presented through select design evaluations.

While Multidisciplinay Design Optimization (MDO) literature focuses mainly on the development of different formulations, through the manipulation of design variables, less attention is generally devoted to the combination of specific MDO formulations with ex-isting nonlinear optimization algorithms. In this paper, the focus is on the application of a Global Optimization (GO) algorithm to an MDO problem. We first introduce and describe some MDO approaches from the literature. Then, we consider our MDO formulation where we deal with the GO box-constrained problem min f (x),f : IR~n —IR. a收起

The Indian Space Research organization (ISRO) is currently embarking on an ambitious human spaceflight (HSF) program. The Indian government approved a budget of ₹ 10,000 Crores (~$1.4 Billion) in December 2018. The Indian HSF program is expected to give impetus to economic activities, employment generation in high-tech areas, human resources development and enhanced industrial capabilities. A robust and sustainable human spaceflight capability will enable India to participate as a collaborating partner in future global space exploration initiatives to Moon, Mars and beyond with long-term national benefits.

Prime Minister Narendra Modi of India in his Independence Day address on August 15, 2018, committed the nation to achieve a Human Spaceflight by the 75th Anniversary of Indian Independence in 2022. Following this momentous political decision, the Indian Union Cabinet approved a budget of ₹ 10,000 Crores (～$1.4 Billion) in December 2018. The design and development of Indian Human Spaceflight Program (HSF) is a highly complex, large scale, public sociotechnical system (STS) with strong interwoven technical, political and social players within a dynamic ecosystem that influences national strategic perspectives, technology capability, foreign policy, economic development and sociocultural spheres of the Republic of India. Indian Space Research Organization (ISRO) has launched the Gaganyaan Mission ("Sky Craft") project with the mandated goal of a first crewed spaceflight to Low Earth Orbit (LEO) and safe recovery by 2022. Since 2007, ISRO has developed several critical technologies for the Human Spaceflight Program. The Indian HSF program is a national endeavor that aims to bring together expertise in diverse disciplines and realize capacity building, spur technological innovation, and inspire youth in science & technology. As part of Gaganyaan Mission, ISRO plans to conduct two orbital tests during 2020-21 with a Cognitive AI Based robot, VyomMitra ("Space Friend"), a half-humanoid before the crewed mission. STS frameworks and related strategic perspectives allow us to understand the interplay of scientific and technological developments with the other dimensions of the society. The sociotechnical systems (STS) frameworks such as Stakeholder Value Network (SVN), STS Architecture models, systems design through phenomena studies and STS Impact through policy levers can be utilized to evaluate the systems design and explore the complex space engineering endeavor. This paper presents the sociotechnical systems (STS) design and strategic perspectives of the Indian Human Spaceflight Program through several frameworks for understanding the emerging challenges in undertaking complex engineering missions for advancing space exploration and socio-economic impact.

India's space program has evolved from an Earth observation orientation to a multidimensional space program that includes several space exploration missions to the Moon, Mars and space observatories. The successful launch of the Chandrayaan-1 mission to the Moon in 2008 is a harbinger for the emerging Indian Space Exploration Program (ISEP). Indian Space Research Organization (ISRO) is scheduled to launch a Mars Orbiter ("Mangalyaan") mission in October-November 2013 and a multi-wavelength astronomical observatory (Astrosat-1) mission to be launched in 2014. The design, development and operation of a spacecraft for an interplanetary mission or for an astronomical observatory are a complex technical project endeavor. Systems engineering tools are utilized to analyze project architectures and technology choices during the project planning phase. Design Structure Matrix (DSM) is a network modeling tool used for designing, developing and managing complex systems. This paper presents a component based interface-technology risk design structure matrix (TR-DSM) analytical framework for evaluating project risk assessment of three of India's space exploration missions - Chandrayaan-1 orbiter mission to the Moon, Mangalyaan orbiter mission to the Mars and the Astrosat-1 multi-wavelength astronomical observatory.
