A Review of Infrasound and Seismic Observations of Sample Return Capsules since the End of the Apollo Era in Anticipation of the OSIRIS-REx Arrival by Elizabeth A. Silber, Daniel C. Bowman, Sarah Albert

“…Furthermore, SRCs are capable of generating shockwaves upon reaching the lower transitional flow regime, and thus can be detected by strategically positioned geophysical instrumentation. NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) SRC is one of only a handful of artificial objects to re-enter the Earth’s atmosphere from interplanetary space since the end of the Apollo era and it will provide an unprecedented observational opportunity. …”

Comparing thermal infrared spectral unmixing algorithms: applications to Bennu and other airless bodies by Brown, EC, Donaldson Hanna, KL, Bowles, NE, Hamilton, VE, Clark, BE, Rogers, AD, Lauretta, DS, OSIRIS-REx Team

The unexpected surface of asteroid (101955) Bennu by Lauretta, DS, Dellagiustina, DN, Bennett, CA, Golish, DR, Becker, KJ, Balram-Knutson, SS, Barnouin, OS, Becker, TL, Bottke, WF, Boynton, WV, Campins, H, Clark, BE, Connolly, HC, D'Aubigny, CY, Dworkin, JP, Emery, JP, Enos, HL, Hamilton, VE, Hergenrother, CW, Howell, ES, Izawa, MRM, Kaplan, HH, Nolan, MC, Rizk, B, Roper, HL, Scheeres, DJ, Smith, PH, Walsh, KJ, Wolner, CWV, Bowles, N, Osiris-Rex Team

“…Here we consider early OSIRIS-REx observations of Bennu to understand how the asteroid's properties compare to pre-encounter expectations and to assess the prospects for sample return. …”

Shape of (101955) Bennu indicative of a rubble pile with internal stiffness by Barnouin, OS, Daly, MG, Palmer, EE, Gaskell, RW, Weirich, JR, Johnson, CL, Al Asad, MM, Roberts, JH, Perry, ME, Susorney, HCM, Daly, RT, Bierhaus, EB, Seabrook, JA, Espiritu, RC, Nair, AH, Nguyen, L, Neumann, GA, Ernst, CM, Boynton, WV, Nolan, MC, Adam, CD, Moreau, MC, Risk, B, Drouet D'Aubigny, C, Jawin, ER, Walsh, KJ, Michel, P, Schwartz, SR, Ballouz, R-L, Mazarico, EM, Scheeres, DJ, McMahon, J, Bottke, W, Sugita, S, Hirata, N, Hirata, N, Watanabe, S, Burke, KN, DellaGuistina, DN, Bennett, CA, Lauretta, DS, OSIRIS-REx Team

“…Here we construct a high-resolution shape model from OSIRIS-REx images. We find that Bennu’s top-like shape, considerable macroporosity and prominent surface boulders suggest that it is a rubble pile. …”

CNN-Based Local Features for Navigation Near an Asteroid by Olli Knuuttila, Antti Kestila, Esa Kallio

“…Our proposed feature extractors and their evaluation leverage synthetic images and real-world data from missions such as NEAR Shoemaker, Hayabusa, Rosetta, and OSIRIS-REx. Our contributions include a trained feature extractor, incremental improvements over existing methods, and a pipeline for training domain-specific feature extractors. …”

Evidence for widespread hydrated minerals on asteroid (101955) Bennu

“…Early spectral data from the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) mission reveal evidence for abundant hydrated minerals on the surface of near-Earth asteroid (101955) Bennu in the form of a near-infrared absorption near 2.7 µm and thermal infrared spectral features that are most similar to those of aqueously altered CM-type carbonaceous chondrites. …”
