In order to identify all the constraints from both engineering and human sides, a meticulous system engineering approach has to be followed and the human sciences, including incorporation of ideas from artists, ergonomists and psychologists, have to be integrated in the very early stages of the mission design.

  • 7. Operations
    7. Operations 7.1 Ground Operations The Exploration Systems Architecture Study (ESAS) team addressed the launch site integra- tion of the exploration systems. The team was fortunate to draw on expertise from members with historical and contemporary human space flight program experience including the Mercury, Gemini, Apollo, Skylab, Apollo Soyuz Test Project, Shuttle, and International Space Station (ISS) programs, as well as from members with ground operations experience reaching back to the Redstone, Jupiter, Pershing, and Titan launch vehicle programs. The team had a wealth of experience in both management and technical responsibilities and was able to draw on recent ground system concepts and other engineering products from the Orbital Space Plane (OSP) and Space Launch Initiative (SLI) programs, diverse X-vehicle projects, and leadership in NASA/Industry/Academia groups such as the Space Propulsion Synergy Team (SPST) and the Advanced Spaceport Technology Working Group (ASTWG). 7.1.1 Ground Operations Summary The physical and functional integration of the proposed exploration architecture elements will occur at the primary launch site at the NASA Kennedy Space Center (KSC). In order to support the ESAS recommendation of the use of a Shuttle-derived Cargo Launch Vehicle (CaLV) and a separate Crew Launch Vehicle (CLV) for lunar missions and the use of a CLV for ISS missions, KSC’s Launch Complex 39 facilities and ground equipment were selected for conversion. Ground-up replacement of the pads, assembly, refurbishment, and/or process- ing facilities was determined to be too costly and time-consuming to design, build, outfit, activate, and certify in a timely manner to support initial test flights leading to an operational CEV/CLV system by 2011.

  • Deployable Modular Frame for Inflatable Space Habitats
    70th International Astronautical Congress (IAC), Washington D.C., United States, 21-25 October 2019. Copyright ©2019 by the International Astronautical Federation (IAF). All rights reserved. IAC-19,B3,8-GTS.2,4,x48931 DMF: Deployable Modular Frame for Inflatable Space Habitats Vittorio Netti1, * 1University of Houston, [email protected] *Corresponding author Abstract Inflatable Space Modules for space exploration are now a reality. In 2016, Bigelow Aerospace tested the first inflatable module Bigelow Expandable Activity Module (BEAM) on the International Space Station (ISS), achieving success. This technology has higher volume limits than other launchers, substantially changing the previous concepts of construction and life in space. Nevertheless, inflatable modules technology lacks a reliable and functional platform to efficiently use all this space. Due to its limited dimension, the International Standard Payload Rack (ISPR), currently used on ISS, is not suitable for this purpose. The project aims at developing a new standard for payload rack in the inflatable space modules: the Deployable Modular Frame (DMF). The DMF expands itself radially from the center of the module, starting from four structural pylons. It creates a solid infrastructure allowing for the configuration of a variety of spaces, including storage space, laboratories, workstations and living quarters. The DMF consists of two main parts: the Deployable Frame (DF) and the Modular Rack (MR). Once the frame is deployed, it provides four linear slots suitable to install the modular racks. The rack is the basic element that allows for the storage of equipment inside the frame. Once they are installed, the racks can slide on the frame’s rails, dynamically changing the space inside the module.

  • Advantages and Limitations of Current Microgravity Platforms for Space Biology Research
    applied sciences Review Advantages and Limitations of Current Microgravity Platforms for Space Biology Research Francesca Ferranti, Marta Del Bianco * and Claudia Pacelli Italian Space Agency, Via del Politecnico snc, 00133 Rome, Italy; [email protected] (F.F.); [email protected] (C.P.) * Correspondence: [email protected] Abstract: Human Space exploration has created new challenges and new opportunities for science. Reaching beyond the Earth’s surface has raised the issue of the importance of gravity for the de- velopment and the physiology of biological systems, while giving scientists the tools to study the mechanisms of response and adaptation to the microgravity environment. As life has evolved under the constant influence of gravity, gravity affects biological systems at a very fundamental level. Owing to limited access to spaceflight platforms, scientists rely heavily on on-ground facilities that reproduce, to a different extent, microgravity or its effects. However, the technical constraints of counterbalancing the gravitational force on Earth add complexity to data interpretation. In-flight experiments are also not without their challenges, including additional stressors, such as cosmic radi- ation and lack of convection. It is thus extremely important in Space biology to design experiments in a way that maximizes the scientific return and takes into consideration all the variables of the chosen setup, both on-ground or on orbit. This review provides a critical analysis of current ground-based and spaceflight facilities. In particular, the focus was given to experimental design to offer the reader the tools to select the appropriate setup and to appropriately interpret the results. Keywords: microgravity; ground-based facility; international Space station; clinostat; RPM; bed rest; CubeSat Citation: Ferranti, F.; Del Bianco, M.; Pacelli, C.
