The near-Earth asteroids (NEAs) may be the most accessible as resources in space to be used for propellant, space manufacturing, and life support. Within this context the multidisciplinary project Ecocel (stands for “Exploitation des Ressources des Corps Célestes”) conducts study on exploration and commercial exploitation of celestial bodies in order to provide recommendations for the French Government. A selection of accessible ressources is an important part of space mining consideration. For this purpose, a database and astrodynamics tools were developed to enable a selection making of asteroids-candidates and a trajectory analysis to compare different mission scenarios. The database contains 326 NEAs, and includes information about basic physical and orbital parameters, collected from JPL Small-Body Database. In addition, the database has been completed by composition data, inferred from spectral classification of NEAs and linked meteorites data. The astrodynamics tools enable to compute one-way and round-trip missions opportunities, using patched two-body approximation, with Lambert solver and ephemerides from the JPL HORIZONS system. The missions characteristics, such as delta-v budget and time of flight, are summarised in the database for each object, and incorporate 20 precomputed solutions optimised by delta-v cost over 2025-2050 launch period. Compared to existing databases, the new database and tools are enable to select potential mission target asteroids by both criteria – composition and accessibility. The data analysis results, the used methods and demonstration on study cases will be presented.
