Slide1: 

International Cooperation for Sustainable Space Exploration 3-6 May 2005 - Abbazia di Spineto, Sarteano,-Italy ISS as Spaceport for Human Moon Mission Andrea Lorenzoni

Slide2: 

The International Space Station can be considered an unique on-orbit facility to support the Human Space Exploration in the short and long period. The following possible ISS exploitation areas have been identified: Test Bed: Preparatory Activities in the short and medium period 2) Orbital Services: Key Exploration Elements in the medium and long period ISS AND HUMAN MOON EXPLORATION

Slide3: 

1) PREPARATORY ACTIVITIES Test Bed for developing and proving new technologies, new capabilities and system reliability Inflatable pressurized elements Pressurized elements to host Resources generation and disposal Regenerative Life support systems Radiation Shelters (passive and active shielding) Pressurized element for equipment servicing High reliability/repairability design validation On orbit maintenance devices and procedures Remote controlled robotic EVA crew support Operational experience for in-space construction ISS AND HUMAN MOON EXPLORATION

ISS AND HUMAN MOON EXPLORATION: 

ISS AND HUMAN MOON EXPLORATION ISS can prove new technologies and, at the same time, can become the test bed for the future programs and the integration and departure point for exploration missions FLECS Moreover (evolved) ISS elements can prove beneficial for space exploration EXAMPLE EXAMPLE Node-like element for in-orbit infrastructure, Fuel Supply Station, Elements of Moon Mars Crewed Ferry

ISS AND HUMAN EXPLORATION: 

ISS AND HUMAN EXPLORATION Conceptual view of the integrated MPLM-Habitat Inflatable Module connected through the standard MPLM port in exploited FECS configuration. Common Berthing Mechanism allows the docking of the MPLM Module. ISS Standard Hatch subsystem allows crew and items transfer between compartments and their isolation during docking manouvres or in case of emergency. Conceptual view of the integrated Node-Habitable Module and Logistic or Laboratory Module connected through the standard Node port. ISS Standard Hatch subsystem allows crew and items transfer among the various compartments and their isolation during docking maneuvers. In case of emergency astronauts can isolate the malfunctioning compartment for troubleshooting. The Node ports can be used for manned-assisted and automatic docking of capsules.

Slide6: 

2) KEY EXPLORATION ELEMENTS Low Earth Orbit Services Overall Systems Integration and Assembly Temporary parking and control of Exploration elements Crew transition port Storage/Resupply Pre-mission maintenance and final checkout Internal Outfitting Assembly of Parts (e.g. MDPS) and cargo elements Intermediate Safe Haven ISS AND HUMAN MOON EXPLORATION

Slide7: 

This Vision for Exploration considers a transportation architecture complementing and supporting the U.S. Space Exploration Vision ISS exploitation as Staging Location for multiple elements assembly (Penalization of 8% for payload delivery from KSC and Kourou consolidated) Multiple launches to LEO and subsequent Staging Approach is envisaged as widely shared . Exploitation of the Earth-LEO segment in terms of: Launchers and LEO Access Vehicles: ATV, HTV, ARIANE, H2, VEGA, DELTA4, SOYUZ, PROGRESS, KLIPPER Earth Reentry Systems: CARV, PARES, SOYUZ adaptation, VEGA Ground segment and Communication Systems ISS AND HUMAN MOON EXPLORATION

Slide8: 

Departure towards Moon from ISS inclination is viable with marginal mission efficiency impacts (corrective maneuvers performed in the Moon vicinity). Inclination of LLO depends on overall timing and midcourse correction; all LLO inclinations can be reached from ISS orbit Launch opportunities: from the ISS orbit for Lunar insertion occurring as a minimum of 9 days according to LLO inclination with launch window lasting approx 1 day; from Earth surface two windows a days are avaiable with short durations and affected by environmental contrains ISS AND HUMAN MOON EXPLORATION

Slide9: 

If return is performed via ISS, crew reentry to Earth can be via conventional (e.g. Soyuz) ISS transport service If return to Earth is not performed via ISS, the relevant DV saving implies development of new reentry capsule (e.g. U.S. CEV) being able to sustain high reentry speed with relevant thermal and structural loads; furthermore the reusability of some architecture elements is not anymore applicable ISS AND MISSION SCENARIO TO MOON

Slide10: 

MOON MISSION CONFIGURATION The Nodes Concept for Cargo Integration and Docking(H-L/01)

Slide12: 

CONCLUSIONS This Vision for Exploration considers the transportation architecture based on ISS as complement and support the U.S. Space Exploration Vision. The technologies and operational experience gained by International Partners and Participants will be exploited. The Moon Human Mission will preserve the already existing international cooperation in ISS Program. Ths cargo integration on ISS, including Habitats, Cargos, Moon Modules, Rovers and Electrical Propulsion have to be deeply considered. Most of Earth-ISS launch capabilities are already existing or planned.
