    PPS02-25 JpGU-AGU Joint Meeting 2017 Hayabusa2 and the formation of the Solar System *Sei-ichiro WATANABE1,2, Hayabusa2 Science Team2 1. Division of Earth and Planetary Sciences, Graduate School of Science, Nagoya University, 2. JAXA/ISAS Explorations of small solar system bodies bring us direct and unique information about the formation and evolution of the Solar system. Asteroids may preserve accretion processes of planetesimals or pebbles, a sequence of destructive events induced by the gas-driven migration of giant planets, and hydrothermal processes on the parent bodies. After successful small-body missions like Rosetta to comet 67P/Churyumov-Gerasimenko, Dawn to Vesta and Ceres, and New Horizons to Pluto, two spacecraft Hayabusa2 and OSIRIS-REx are now traveling to dark primitive asteroids.The Hayabusa2 spacecraft journeys to a C-type near-earth asteroid (162173) Ryugu (1999 JU3) to conduct detailed remote sensing observations and return samples from the surface. The Haybusa2 spacecraft developed by Japan Aerospace Exploration Agency (JAXA) was successfully launched on 3 Dec. 2014 by the H-IIA Launch Vehicle and performed an Earth swing-by on 3 Dec. 2015 to set it on a course toward its target. The spacecraft will reach Ryugu in the summer of 2018, observe the asteroid for 18 months, and sample surface materials from up to three different locations. The samples will be delivered to the Earth in Nov.-Dec. 2020. Ground-based observations have obtained a variety of optical reflectance spectra for Ryugu. Some reported the 0.7 μm absorption feature and steep slope in the short wavelength region, suggesting hydrated minerals.

(M.S., Aerospace Engineering Sciences) Orbit Options for an Orion-Class Spacecraft Mission to a Near-Earth Object Thesis directed by Prof. Daniel Scheeres Based on the recommendations of the Augustine Commission, President Obama has pro- posed a vision for U.S. human spaceflight in the post-Shuttle era which includes a manned mission to a Near-Earth Object (NEO). A 2006-2007 study commissioned by the Constellation Program Advanced Projects Office investigated the feasibility of sending a crewed Orion spacecraft to a NEO using different combinations of elements from the latest launch system architecture at that time. The study found a number of suitable mission targets in the database of known NEOs, and pre- dicted that the number of candidate NEOs will continue to increase as more advanced observatories come online and execute more detailed surveys of the NEO population.

  • Attitude Control Dynamics of Spinning Solar Sail “IKAROS” Considering

    Attitude Control Dynamics of Spinning Solar Sail “IKAROS” Considering

    Attitude Control Dynamics of Spinning Solar Sail “IKAROS” Considering Thruster Plume Osamu Mori, Yoji Shirasawa, Hirotaka Sawada, Ryu Funase, Yuichi Tsuda, Takanao Saiki and Takayuki Yamamoto (JAXA), Morizumi Motooka and Ryo Jifuku (Univ. of Tokyo) Abstract In this paper, the attitude dynamics of IKAROS, which is spinning solar sail, is presented. First Mode Model of out-of-plane deformation (FMM) and Multi Particle Model (MPM) are introduced to analyze the out-of-plane oscillation mode of spinning solar sail. The out-of-plane oscillation of IKAROS is governed by three modes derived from FMM. FMM is very simple and valid for the design of attitude controller. Considering the thruster configuration of IKAROS, the force on main body and sail by thruster plume as well as reaction force by thruster are integrated into MPM. The attitude motion after sail deployment or reorientation using thrusters can be analyzed by MPM numerical simulations precisely. スラスタプルームを考慮したスピン型ソーラーセイル「IKAROS」の姿勢制御運動 森 治，白澤 洋次，澤田 弘崇，船瀬 龍，津田 雄一，佐伯 孝尚，山本 高行（JAXA）， 元岡 範純，地福 亮（東大） 摘要 本論文ではスピン型ソーラーセイル IKAROS の姿勢運動について示す．スピン型ソーラーセイル を解析するために一次面外変形モデルおよび多粒子モデルを導入する．まず，一次面外変形モデ ルから導出される 3 つのモードが IKAROS の面外運動を支配していることを示す．このモデルは 非常に簡易であり，姿勢制御設計に有効であると言える．一方，多粒子モデルに対しては， IKAROS のスラスタ配置を考慮して，スラスタの反力だけでなくスラスタプルームが本体や膜面 に及ぼす力を組み込み，セイル展開後およびスラスタによるマヌーバ後の姿勢運動を数値シミュ レーションにより詳細に解析する． 1.

Extended Emission Calibration! AKARI (formerly ASTRO-F), is the second Japanese satellite FAST is a program that allows for interactive Original calibration of the FIS detector was done using diffuse galactic cirrus emission dedicated to infrared (IR) astronomy, from the Institute of assessment of the data quality and on-the-fly with low photon counts. On the other hand, bright point sources can cause the slow Space and Astronautical Science (ISAS) of the Japanese corrections to the time-series data on a pixel-by- transient response effect because of high photon counts. Marginally extended sources Aerospace Exploration Agency (JAXA). Its main objective is pixel basis in order to manually correct glitches consist of regions of high and low photon counts, and therefore, only parts of them suffer to perform an all-sky survey with better spatial resolution and that would have been missed in the pipeline from the slow transient response effect. Hence, we needed to devise a specific method to wider wavelength coverage than IRAS (first US, UK, Dutch process. These corrections include: (1) eliminate address the detector response as a whole. This method uses a contour aperture to include infrared satellite launched in 1983), mapping the entire sky in bad on-sky calibration sequences, (2) flag out both the faint and bright emission by setting a threshold of background + 3#.! six infrared bands.
