“…As a measure of the accessibility of the NEO population, the "H-plot" has been introduced by Perozzi et al (2001) for discussing the selection of targets when both scientific and mission analysis considerations are taken into account. We apply this method of analysis here and display the results in Fig 1. The H-plot method exploits Hohmann-like transfer trajectories for evaluating "best case" delta-V (∆V) budgets for rendezvous missions to each individual member of the NEO population.…”

Abstract-Using an H-plot analysis, we identify 234 currently known near-Earth objects that are accessible for rendezvous with a "best case" delta-V of less than 7 km/s. We provide a preliminary compositional interpretation and assessment of these potential targets by summarizing the taxonomic properties for 44 objects. Results for one-half (22) of this sample are based on new spectroscopic measurements presented here. Our approach provides an easy-to-update method for giving guidelines to both observers and mission analysts for focusing on objects for which actual mission opportunities are most likely to be found. Observing prospects are presented for categorizing the taxonomic properties of the most accessible targets that are not yet measured.

“…Asteroid 1996 FG3 was identified as a good target for a space mission, as its orbit presents a ΔV of only 5.16 km s −1 (Perozzi et al 2001;Christou 2003;Binzel et al 2004b). Its primitive physical and binary nature also makes this asteroid an interesting target for a scientific rendezvous mission, thus it was chosen as a primary target for the new ESA Marco Polo-R mission, selected for the assessment study phase of ESA M3 missions.…”

Context. Near-Earth asteroid (175706) 1996 FG3 is the primary target of the ESA Marco Polo-R mission, which was selected for the assessment study phase of ESA M3 missions. This is a primitive (C-type), binary asteroid that will allow new research to be performed. The primary is a rapidly rotating (3.6 h) small asteroid (1.4 km diameter) that is almost spherical and has a satellite of ∼400 m. Aims. We analyse new ground-based spectroscopic data of 1996 FG3 to help us characterise its surface composition and prepare for the mission. Methods. We obtained a near-infrared spectrum covering the range 0.8-2.5 μm, using the camera-spectrograph NICS at the 3.6 m telescope TNG (Telescopio Nazionale Galileo), located at "El Roque de los Muchachos" Observatory on La Palma, Spain. We combine our near-infrared spectrum with previously published data, and compare all the available spectra of this asteroid with the spectra of meteorites to constrain the mineralogy of the asteroid. Results. Our spectrum of FG3 differs remarkably from previously published ones. Spectral classification performed using the complete visible and near-infrared range yields more than one result, varying from C to Xk types. However, all the possible spectral types indicate that this asteroid is a primitive object. The comparison with meteorites behaves in the same way, providing several good matches to our new near-infrared spectrum (CM2 carbonaceous chondrite, and L6 and H4 ordinary chondrites), and only one match in the case of the previously published spectra (weakly shocked H4 ordinary chondrite, dark vein). The albedo of the asteroid (∼0.04), is typical of a primitive object, and is consistent with the reflectance value at 0.55 μm of the CM2 carbonaceous chondrite. Further observations will be essential to help us characterise more clearly the mineralogy of this asteroid.

“…Indeed, some near-Earth asteroids (NEAs) are easier to reach than the Moon. The energy and flight time required to reach the NEA (10302) 1989 ML are relatively small, comparable to those for the Hayabusa target (25143) Itokawa (Perozzi et al, 2001;Christou 2003;Binzel et al, 2004), making it a very attractive spacecraft target for rendezvous missions. 1989 ML has been considered as a possible target for both the Japanese Hayabusa and the European Don Quijote missions (see, for example, Binzel et al, 2001, and http://www.esa.int/SPECIALS/NEO/); at the time of writing further missions to NEAs are being planned in Japan, Europe, and the USA, for which 1989 ML may be considered as a target.…”

The Amor-type near-Earth asteroid (10302) 1989 ML has an "Earth-like" orbit (period 1.44 yr, eccentricity 0.14, inclination 4.4°), therefore the energy required to reach it from the Earth is relatively small making it a very attractive target for rendezvous missions. We have observed 1989 ML in the thermal-infrared using the Spitzer Space Telescope, and compared these data with optical and near-infrared observations. The Spitzer results imply a diameter of 0.28 ± 0.05 km and a geometric albedo of 0.37 ± 0.15; together with the reflectance spectrum they are consistent with the relatively rare E classification.
