The exploration of energization and radiation in geospace (ERG) satellite, nicknamed "Arase," is the second satellite in a series of small scientific satellites created by the Institute of Space and Astronautical Science of the Japan Aerospace Exploration Agency. It was launched on December 20, 2016, by the Epsilon launch vehicle. The purpose of the ERG project is to investigate how high-energy (over MeV) electrons in the radiation belts surrounding Earth are generated and lost by monitoring the interactions between plasma waves and electrically charged particles. To measure these physical processes in situ, the ERG satellite traverses the heart of the radiation belts. The orbit of the ERG is highly elliptical and varies due to the perturbation force: the apogee altitude is approximately 32,200-32,300 km, and the perigee altitude is 340-440 km. In this study, we introduce the scientific background for this project and four major challenges that need to be addressed to effectively carry out this scientific mission with a small satellite: (1) dealing with harsh environmental conditions in orbit and electromagnetic compatibility issues, (2) spin attitude stabilization and avoiding excitation of the libration by flexible structures, (3) attaining an appropriate balance between the mission requirements and the limited resources of the small satellite, and (4) the adaptation and use of a flexible standardized bus. In this context, we describe the development process and the flight operations for the satellite, which is currently working as designed and obtaining excellent data in its mission.

Study on an Advanced Attitude Determination Algorithm for the ERG Spacecraft
Söken, Halil Ersin; Asamura, Kazushi; Nakamura, Yosuke; Takashima, Takeshi (null; 2017-06-07)
AXA’s Arase Spacecraft, which is formerly known as Exploration of Energization and Radiation in Geospace (ERG), was launched on 20 December 2016. The spacecraft is spin-stabilized. Its mission is exploring how relativistic electrons in the radiation belts are generated during space storms. Two on-ground attitude determination algorithms are considered for the mission: a conventional simple algorithm that inherits from old missions and an advanced algorithm that is newly designed. This paper discusses the de...
Mission Experience for Spinning Spacecraft Attitude Filtering with Spin Parameters
Söken, Halil Ersin; Asamura, Kazushi; Nakamura, Yosuke; Takashima, Takeshi; Shinohara, Iku (2019-06-21)
JAXA's Arase Spacecraft, which is formerly known as Exploration of Energization and Radiation in Geospace (ERG), was launched on 20 December 2016 and has been in orbit for almost 3 years. The spacecraft is spin-stabilized. Its mission is exploring how relativistic electrons in the radiation belts are generated during space storms. Two on-ground attitude determination algorithms are used for the mission: a conventional simple algorithm that inherits from old missions and an advanced algorithm that is newly d...
Filtering-Based Three-Axis Attitude Determination Package for Spinning Spacecraft: Preliminary Results with Arase
Söken, Halil Ersin; Asamura, Kazushi; Nakamura, Yosuke; Takashima, Takeshi; Shinohara, Iku (2020-07-01)
JAXA's ERG (Exploration of Energization and Radiation in Geospace) Spacecraft, which is nicknamed Arase, was launched on 20 December 2016. Arase is a spin-stabilized and Sun-oriented spacecraft. Its mission is to explore how relativistic electrons in the radiation belts are generated during space storms. Two different on-ground attitude determination algorithms are designed for the mission: A TRIAD-based algorithm that inherits from old missions and a filtering-based new algorithm. This paper, first, discus...
Forecasting of ionospheric electron density trough for characterization of aerospace medium
Kocabaş, Zeynep; Tulunay, Yurdanur; Department of Aerospace Engineering (2009)
Modeling the ionosphere, where the effects of solar dynamo becomes more effective to space based and ground borne activities, has an undeniable importance for telecommunication and navigation purposes. Mid-latitude electron density trough is an interesting phenomenon in characterizing the behavior of the ionosphere, especially during disturbed conditions. Modeling the mid-latitude electron density trough is a very popular research subject which has been studied by several researchers until now. In this work...
NASA Astrobiology Institute: Supporting interdisciplinary research and education
Aydınoğlu, Arsev Umur (2019-06-29)
The NASA Astrobiology Institute (NAI) was established in 1998 as a virtual institute in order to answer some of these questions from a scientific perspective through developing the interdisciplinary field of astrobiology and supporting relevant flight missions. This study evaluates NAI's activities by looking at its contributions to interdisciplinary astrobiology research and education. The NAI has had a huge impact on astrobiology research; astrobiology articles have bloomed after the Institu...
