Abstract

Hayabusa2 is the Japanese Asteroid Return Mission and targeted the carbonaceous asteroid Ryugu, conducted by the Japan Aerospace Exploration Agency (JAXA). The goal of this mission was to conduct proximity operations including remote sensing observations, material sampling, and a Small Carry-On Impact experiment, as well as sample analyses. As of September 2020, the spacecraft is on the way back to Earth with samples from Ryugu with no critical issues after the successful departure in November 2019. Here, we propose an extended mission in which the spacecraft will rendezvous with a small asteroid with ~30 m - ~40 m in diameter that is rotating at a spin period of ~10 min after an additional ~10-year cruise phase. We introduce that two scenarios are suitable for the extended mission. In the first scenario, the spacecraft will perform swing-by maneuvers at Venus once and Earth twice to arrive at asteroid 2001 AV43. In the second scenario, it will perform swing-by maneuvers at Earth twice to reach asteroid 1998 KY26. In both scenarios, the mission will continue until the early 2030s. JAXA recently released the decision that the spacecraft will rendezvous with 1998 KY26. This paper focuses on our scientific assessments of the two scenarios but leaves the decision process to go to 1998 KY26 for future reports. Rendezvous operations will be planned to detail the physical properties and surrounding environments of the target, one of the smallest elements of small planetary bodies. By achieving the planned operations, the mission will provide critical hints on the violent histories of collisions and accumulations of small bodies in the solar system. Furthermore, the established scientific knowledge and techniques will advance key technologies for planetary defense., Comment: 51 pages, 9 figures, and 10 tables.

17. Lighting features in Japanese traditional Architecture

Author

Cabeza-Lainez, JM, Saiki, T, Almodovar-Melendo, JM, and Jiménez-Verdejo, JR

Abstract

Japanese Architecture has always shown an intimate connection with nature. Most materials are as natural as possible, like kaya vegetal roofing, wooden trusses and rice-straw mats (tatami). Disposition around the place, follows a clever strategy of natural balance often related to geomancy like Feng-Shui and to the observance of deeply rooted environmental rules. In this paper we would like to outline all of the former, but also stressing the role of day-lighting in architecture. Unlike Spain, day-lighting is a scarce good in Japan as the weather is often stormy and cloudy. Maximum benefit has to be taken of the periods in which the climate is pleasant, and a variety of approaches has been developed to deal with such conditions; latticed paper-windows (shôji), overhangs (noki) and verandas oriented to the South (engawa), are some of the main features that we have modelled with the aid of our computer program. The results have been validated by virtue of on site measurements. The cultural aspect of this paper lies not only in what it represents for the evolution of Japanese and Oriental Architecture but also in the profound impression that those particular lighting systems had for distinguished modern architects like Bruno Taut, Antonin Raymond or Walther Gropius and the contemporary artist Isamu Noguchi, a kind of fascination that we may say is lingering today.

Abstract

CO CV CM CI Ryugu A Ryugu C 0.0 0.5 1.0 1.5 44/40CaSRM915a (age corrected) The Hayabusa2 spacecraft has returned samples from the Cb-type asteroid (162173) Ryugu to Earth. Previous petrological and chemical analyses support a close link between Ryugu and CI chondrites that are presumed to be chemically the most primitive meteorites with a solar-like composition. However, Ryugu samples are highly enriched in Ca compared to typical CI chondrites. To identify the cause of this discrepancy, here we report stable Ca isotopic data (expressed as delta 44/40CaSRM915a) for returned Ryugu samples collected from two sites. We found that samples from both sites have similar delta 44/40CaSRM915a (0.58 +/- 0.03 parts per thousand and 0.55 +/- 0.08 parts per thousand, 2 s.d.) that fall within the range defined by CIs. This isotopic similarity suggests that the Ca budget of CIs and Ryugu samples is dominated by carbonates, and the variably higher Ca contents in Ryugu samples are due to the abundant carbonates. Precipitation of carbonates on Ryugu likely coincided with a major episode of aqueous activity dated to have occurred similar to 5 Myr after Solar System formation. Based on the pristine Ryugu samples, the average delta 44/40CaSRM915a of the Solar System is defined to be 0.57 +/- 0.04 parts per thousand (2 s.d.).
