    Return on Experience (ROE)
    The transfer of experience from previous missions to new projects for enhancement of efficiency, reliability and safety. This concerns not only the staffing of new projects with experienced people but also the capitalization of past experience gained in the design, development, qualification and/or operations of a relevant mission. Current experience is well published in SpaceOps symposia papers and presentations. ''See AIAA papers: 2006-5800, 2006-5810 , 2006-5904, 2006-5919 , 2006-5955 and sub-sessions within the 2006 conference on “Operations Experience” and “Flight Operations Execution”.

    On of the selected "best topic paper" of the SpaceOps 2012 Conference was the "Efficacy of the Dawn Vesta Science Plan" (AIAA-2012-1275915), describing the results of the execution of the science operations plan and how that compared to the assumptions that informed the development of the plan.
    Security (Communications)
    Communications security for spaceflight means {http://cdncache1-a.akamaihd.net/items/it/img/arrow-10x10.png} measures to keep the transmitted information from and to a spacecraft via the various communication links secure (confidential) and to prohibit unauthorized access to this information for the purpose of gaining this information and/or altering it.

    AIAA 2016-2525: Reliable Commanding and Telemetry Operations Using CFDP (CCSDS File Delivery Protocol)

    Service Oriented Architecture
    Service oriented architecture is a flexible set of design principles providing a system modelled as a loosely-integrated {http://cdncache1-a.akamaihd.net/items/it/img/arrow-10x10.png} of services (2010-1922). Services are functional capabilities exchanged between service providers and service consumers within the system via well defined interfaces (2010-1903). Systems based on SOA are loosely related to OS and programming languages, which allows them to be easy to maintain and to manage (2008-3330). Interoperability, extensibility, adaptability and generic applicability are the key advantages of SOA-based systems. Basics of service oriented architectures and interactions of applications, components and infrastructure are presented (2006-5592 and 2008-3504). The CCSDS Mission Operation framework (CCSDSMO) based on a Service Oriented Architecture is introduced in 2008-3239. One paper advocates that higher integration of flight and ground aspects should be event driven not service driven to improve configurability and extensibility (2006-5531).
    Simulators
    Simulators are replicas of the entire spacecraft or components including mock up equipment to simulate (more or less realistically) real zero-gravity, in situ flight behavior. Simulators are used to check-out spacecraft functions on the ground and to train and qualify operations personnel pre-flight. During operations simulators are used for failure investigation and test of software reloads and/or new operations procedures.

    Software Development
    Method for developing flight and ground software under the specific aspects of uniqueness, functional verification, re-usability, adaptability, certification and maintainability during space-missions, respecting limited financial resources. AGILE programming as a new method to reduce overall S/W development cost in a mission control environment is recommended AIAA paper 2006-5701 . The use of complex and flexible telemetry/telecommand standard packages often do not yield the expected cost savings, because of high customization efforts (Round Table). The ESA Standardization Board has launched an ESA wide initiative aimed at standardizing Secure Software Engineering (SSE). The SpaceOps2014 Conference paper AIAA 2014-1799 describes this process. Another SpaceOps2014 paper describes an open source development for data integration and display with the core objective to enable collaboration, open the software to outside innovation and stimulate a community of open source mission operations participants and contributors (AIAA 2014-1762) . The ESA Ground Systems Common Core (EGS-CC) is theEuropean initiative to develop a common infrastructure to support space systems monitoring and control. The initiative is being performed as a collaboration between ESA, European national agencies and European industry (AiAA 2014-1767).

    Operations of satellites in Low-Earth Orbit (LEO) have been based on exploiting the maximum time of visibility of satellites over their ground stations. In a 2010 paper (2010-1942), it is shown that a key parameter for communication between a satellite and a ground station is not the time of visibility but the amount of telemetry data which can be transmitted from the satellite to the ground station in the downlink.

    Technology for establishing communications between a spacecraft and the appropriate ground segment (ground based facilities).
    It comprises all means of communications and associated technical support systems used between a spacecraft (manned or unmanned) and the ground personnel (flight and payload operators). Space communications (Space-to-Ground, Ground-to-Space and Space-to-Space) always demand higher transmission capabilities (data rates and protocols) for up- and downlink data transfer. Interesting and promising validation results of interplanetary Ka-band link (high rate) communications usage were presented at SpaceOps 2006 AIAA paper 2006-5787. The ESA Ground segment Management is looking into Ka-band expansion as well (Plenary Session, ''SpaceOps 2006''). For interplanetary (e.g. Lunar/Mars) missions, it is proposed to use IP rather than point-to-point protocols (Round Table).

    Constellation
    Constellation is the name of the NASA program to implement the “Vision for Space Exploration” (VSE) as installed by President George W. Bush consisting of the shuttle derived two stage launcher Ares I (2008-3562) to service together with the crew transport vehicle “Orion Orbiter” the ISS. The Ares V launch vehicle will transport “Orion” together with the moon lander “Altair” into earth orbit to be docked there and maneuvered into a moon trajectory. “Altair” will land on the moon while “Orion” is orbiting the moon waiting for “Altair’s” return to fly the crew safely back to earth. The same concept might be applied for exploring Mars.Ground operations aspects for the Ares I and Ares V launch vehicles are described in 2008-3563

    The degree of on-board control. Theoretically, total crew autonomy would be a self-contained, independent flight system without any interaction with ground operators. A certain degree of crew autonomy is mandatory with independent and automated on-board planning systems AIAA paper 2006-5526, because of the creasing delay-times for long distance human spaceflight.

    Ground Operations (Mehtods(Methods and Tools)
    All activities in or between ground based facilities for monitoring and controlling spacecraft during their mission as well securing the mission return. It covers the preparation, qualification and operations of a mission-dedicated ground segment and appropriate infrastructure including Antennas, Control Centers and Communication means and Interfaces. Ground operations in this context covers the design, implementation and qualification of a particular ground segment, the provision of ground segment operations tools, provision of simulation means, ground segment operation, configuration management and maintenance of the ground segment. The main challenge is the implementation and operations of high-quality, cost-efficient and secure space-to-ground, space-to-space and ground-to-ground communications respecting a multitude of different standards and protocols (see also papers in the categories Standards, Ground Systems, Communications and Tracking).

    Ground System Reliability
    Success of the Constellation Program’s lunar architecture requires successfully launching two vehicles, Ares I/Orion and Ares V/Altair, within a very limited time period. The reliability and maintainability of flight vehicles and ground systems must deliver a high probability of successfully launching the second vehicle in order to avoid wasting the on-orbit asset launched by the first vehicle. The Ground Operations Project determined which ground subsystems had the potential to affect the probability of the second launch and allocated quantitative availability requirements to these subsystems. The Ground Operations Project also developed a methodology to estimate subsystem reliability, availability, and maintainability to ensure that ground subsystems complied with allocated launch availability and maintainability requirements. The verification analysis developed quantitative estimates of subsystem availability based on design documentation, testing results, and other information.
