About Journal of Astronomy and Space Sciences

The Journal of Astronomy and Space Sciences (JASS; J. Astron. Space Sci.) is the official publication of the Korean Space Science Society (KSSS), the most prestigious academic society in the fields of space science and space applications in Korea. JASS is an international journal devoted to the publication of fundamental and applied investigations in all aspects of spacerelated science and technology. It was launched in 1984 and is published quarterly. Each article published is assigned a unique DOI that serves to identify the article in the digital environment. JASS is an open access journal; consequently, the full texts of articles are free for all users to read and use. The papers published in JASS are accessible on the journal homepage (http://janss.kr), the DOAJ website, and the SAO/NASA ADS website. JASS has been indexed by KCI and SCOPUS since 2007 and 2012, respectively. Additionally, JASS was re-indexed by DOAJ and newly indexed in the ESCI (Emerging Sources Citation Index) by Clarivate Analytics in 2017. This journal is supported in part by a Grant-in-Aid for the publication of scientific research from the Korean Federation of Science and Technology Societies (KOFST).

Review of Space Debris Modeling Methods and Development Direction of the Korean Space Debris Models

Jinsung Lee, Hangyeol Kim, Eun Jung Choi, Jin Choi, Jiwoong Yu, Junghyun Jo, Jaemyung Ahn

J. Astron. Space Sci. 2024;41(4):209-223.
https://doi.org/10.5140/JASS.2024.41.4.209

Space debris poses significant threats to spacecraft and human activities in space. Accurate modeling of space debris is crucial for understanding and mitigating these risks, ensuring the sustainability of the space environment. This paper discusses the importance of space debris modeling in the space environment, highlighting its critical role in safeguarding assets in orbit. Two primary methods of space debris modeling, namely the 1D and 3D approaches, are discussed in detail, and their respective strengths and limitations are elucidated. Fur...

Hemispheric Asymmetry of Annual/Semi-Annual Oscillations in Mesospheric Neutral Winds and Pressure Between Northern and Southern High Latitude Regions

Hosik Kam, Jeong-Han Kim, Changsup Lee, Yong Ha Kim

J. Astron. Space Sci. 2024;41(4):225-233.
https://doi.org/10.5140/JASS.2024.41.4.225

We present oscillating features from long-term neutral wind (meteor radar) and pressure (microwave limb sounder) measurements at Esrange (67°N, 20°E, 2007–2018) in the northern hemisphere and King Sejong Station (KSS; 62°S, 58°W, 2007–2017) in the Southern Hemisphere using the Lomb-Scargle periodogram and wavelet analysis. In zonal winds and pressure, we estimated the height profiles for the amplitude ratio between annual oscillation (AO) and semi-annual oscillation (SAO) at both sites. Over KSS, the ratio indicates that SAO increases...

Apprehensions with Regard to Commercial Space Flight: Outlook on Space Law

Sheer Abbas

The advent of “space tourism” has induced outer space law to respond and adapt to this dramatic growth because of the principled contribution of private entities in these activities. This article discusses the main legal aspects of licensing, supervision, liability, registration, and health side effects, and how these reveal the influence of space tourism. Because of the moral participation of private individuals in these activities, “space tourism” demands that outer space law be modified and adaptable. Although many issues of ship, cr...

Geometric Calibration of the ShadowCam Instrument on the Korea Pathfinder Lunar Orbiter

Emerson Jacob Speyerer, Mark Southwick Robinson, David Carl Humm, Nicholas Michael Estes, Victor Hugo Silva, Robert Vernon Wagner, Prasun Mahanti, Scott Michael Brylow

J. Astron. Space Sci. 2024;41(4):249-270.
https://doi.org/10.5140/JASS.2024.41.4.249

The ShadowCam instrument on the Danuri spacecraft provides high-resolution views of shadowed portions of the Moon, which are illuminated by naturally scattered light from nearby sunlit terrain. The sensitive time-delay integration detector captures high signal-to-noise observations within the permanently shadowed regions and areas in shadow for part of the year. We characterized the geometric properties of the images, enabling accurate placement of observations within the lunar cartographic framework. This work describes the internal and extern...

Ground Calibration with Orthogonality Correction for Tri-Axis Fluxgate Magnetometer for CAS500-3

Dooyoung Choi, Seunguk Lee, Jimin Hong, Su-Hwan Park, SeongOg Park, Wonho Cha, Jinkyu Kim, Bonju Gu, Po Gyu Park, Sungjung Joo, Cheong Rim Choi, Dae-Young Lee, Kwangsun Ryu

J. Astron. Space Sci. 2024;41(4):271-281.
https://doi.org/10.5140/JASS.2024.41.4.271

This paper presents ground calibration and orthogonality correction methods for the tri-axis fluxgate magnetometer (FGM), named as adaptive in-phase magnetometer (AIMAG), aboard the CAS500-3 satellite. The orthogonality errors of the FGM among the axes can lead to significant inaccuracies in magnetic field measurements. In this study, we employed Helmholtz coils and an autocollimator to apply controlled magnetic fields and adjust the magnetometer’s alignment. By deriving the correction matrix, we could transfer the sensor axes to the ideal or...
