This Edition has been compiled to celebrate 30years of Space Shuttle missions and to coincide with the last mission. NASA's greatest achievement was the creation of a reusable spacecraft. The Apollo spacecraft cost an astronomical sum to produce and were single-use only. The heat from Earth's atmosphere essentially disintegrated the shielding used to protect the spacecraft. The spacecraft also landed in the ocean, and the impact and sea water damaged the equipment. To remedy this, NASA built a spacecraft that had two rocket launchers attached to an external fuel tank and an orbiter module. They coated the spacecraft with protective heat-resistant ceramic tiles and changed the landing design to a glider-style. It took nine years of preparation, from 1972 to 1981, before the first mission. I would like to thank NASA/JPL and ESA for the information that has been compiled in this special edition.

  • The International Space Station (ISS) Is an Experiment in the Design, Development, and Assembly of an Orbital Space Facility. It
    The International Space Station (ISS) is an experiment in the design, development, and assembly of an orbital space facility. It serves as a elements habitat for its crew, a command post for orbital operations, and a port for the rendezvous and berthing of smaller orbiting vehicles. It functions as an orbital microgravity and life sciences laboratory, a test bed for new technologies in areas like life support and robotics, and a platform for astronomical and Earth observations. PMA 2 berthed on Node 1 serves as a primary docking port for the Space Shuttle. The U.S. Lab Module Destiny provides research and habitation accommodations. Node 2 is to the left; the truss is mounted atop the U.S. Lab; Node 1, Unity, is to the right; Node 3 and the Cupola are below and to the right. INTERNATIONAL SPACE STATION GUIDE ELEMENTS 23 ARCHITECTURE DESIGN EVOLUTION Architecture Design Evolution Why does the ISS look the way it does ? The design evolved over more than a decade. The modularity and size of the U.S., Japanese, and European elements were dictated by the use of the Space Shuttle as the primary launch vehicle and by the requirement to make system components maintainable and replaceable over a lifetime of many years. When the Russians joined the program in 1993, their architecture was based largely on the Mir and Salyut stations they had built earlier. Russian space vehicle design philosophy has always emphasized automated operation and remote control. The design of the interior of the U.S., European, and Japanese elements was dictated by four specific principles: modularity, maintainability, reconfigurability, and accessibility.

This paper investigates the possibility of exploring the Martian system by using a manned spacecraft, the Crew Interplanetary Vehicle, (CIV) and a cargo vehicle, the Mars Automated Transfer Vehicle (MATV). The main payloads, carried by the high efficiency solar electric MATV, are a two-passenger spacecraft landing on Phobos; an orbital laboratory and a rover network for deployment to the surface of Mars. In order to cope with the constraints imposed for a human mission to deep space, the feasibility study has been performed using a human-centred design approach. The main output of the mission is the preliminary design of the CIV. Furthermore, the main parameters of the MATV as well as the orbital laboratory and the Phobos Lander were estimated. The manned spacecraft is designed to depart from LEO in 2036 using chemical propulsion. Once in Mars proximity, the main manoeuvres will be performed using nuclear thermal propulsion and a bi-propellant chemical system will perform the minor manoeuvres.
