Near Earth Objects As Resources for Space Industrialization
Solar System Development Journal (2001) 1(1), 1-31 http://www.resonance-pub.com ISSN:1534-8016 NEAR EARTH OBJECTS AS RESOURCES FOR SPACE INDUSTRIALIZATION MARK SONTER Consultant, Asteroid Enterprises Pty Ltd, 28 Ian Bruce Crescent, Balgownie, New South Wales 2519, Australia [email protected] (Received 11 February 2001, and in final form 13 August 2001*) This paper reviews concepts for mining the Near-Earth Asteroids for supply of resources to future in-space industrial activities. It identifies Expectation Net Present Value as the appropriate measure for determining the technical and economic feasibility of a hypothetical asteroid mining venture, just as it is the appropriate measure for the feasibility of a proposed terrestrial mining venture. In turn, ENPV can obviously be used as a ‘design driver’ to sieve the alternative options, in selection of target, mission profile, mining and processing methods, propulsion for return trajectory, and earth-capture mechanism. 1. INTRODUCTION The Near Earth Asteroids are potential impact threats to Earth, but also a particularly accessible subset of them does provide potentially attractive targets for resources to support space industrialization. Robust technical and economic approaches to evaluation of the feasibility of proposed projects are necessary for assessment of such space mining ventures. This paper discusses the technical engineering and mission–planning choices and shows how the concept of probabilistic Net Present Value can be used to optimize these choices, and hence select between alternative asteroid mining mission designs. The generic mission reviewed envisages a lightweight remote (teleoperated) or semiautonomous miner, recovering products such as water or nickel-iron metal, from highly- accessible NEAs, and returning it to Low Earth Orbit (LEO), for sale and use in LEO, using solar power and some of the recovered mass as propellant. -

Disk-integrated photometric data of asteroids do not contain accurate information on shape details or size scale. Additional data such as disk-resolved images or stellar occultation measurements further constrain asteroid shapes and allow size estimates. Aims. We aim to use all available disk-resolved images of about forty asteroids obtained by the Near-InfraRed Camera (Nirc2) mounted on the W.M. Keck II telescope together with the disk-integrated photometry and stellar occultation measurements to deter- mine their volumes. -
THE STRANGE CASE of 133P/ELST-PIZARRO: a COMET AMONG the ASTEROIDS1 Henry H

THE STRANGE CASE OF 133P/ELST-PIZARRO: A COMET AMONG THE ASTEROIDS1 Henry H. Hsieh, David C. Jewitt, and Yanga R. Ferna´ndez Institute for Astronomy, University of Hawaii, 2680 Woodlawn Drive, Honolulu, HI 96822; [email protected], [email protected], [email protected] Received 2003 August 7; accepted 2004 January 20 ABSTRACT We present a new investigation of the comet-asteroid transition object 133P/(7968) Elst-Pizarro. We find mean optical colors (BÀV =0.69Æ 0.02, VÀR =0.42Æ 0.03, RÀI =0.27Æ 0.03) and a phase-darkening coefficient ( =0.044Æ 0.007 mag degÀ1) that are comparable both to other comet nuclei and to C-type asteroids. As in 1996, when this object’s comet-like activity was first noted, data from 2002 show a long, narrow dust trail in the projected orbit of the object. Observations over several months reveal changes in the structure and brightness of this trail, showing that it is actively generated over long periods of time. Finson-Probstein modeling is used to constrain the parameters of the dust trail. We find optically dominant dust particle sizes of ad 10 mreleased À1 with low ejection velocities (vg 1.5 m s ) over a period of activity lasting at least 5 months in 2002. The double- peaked light curve of the nucleus indicates an aspherical shape (axis ratio a/b 1.45 Æ 0.07) and rapid rotation (period Prot = 3.471 Æ 0.001 hr). -
