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).

Astroparticle Physics and Astronuclear Physics at Exascale: Scientific Opportunities Enabled by the KISTI-6 Supercomputer

Kihyeon Cho

J. Astron. Space Sci. 2026;43(3):117-128.
https://doi.org/10.5140/JASS.2026.43.3.117

The convergence of theoretical modeling, observational astronomy, and high-performance computing has ushered in a new era in astroparticle physics and astronuclear physics. In this review, we summarize major simulation-based research activities enabled by Korea’s national supercomputing infrastructure, with particular emphasis on results obtained using the KISTI-5 supercomputer (Nurion). These include nuclear lattice effective field theory calculations, neutron drip line predictions, nuclear equation-of-state studies, and large-scale simulati...

Soviet Lunar Science in Context: From Luna to Artemis

Ulkar Karimova, Yu Yi, Kyungguk Min

J. Astron. Space Sci. 2026;43(3):129-146.
https://doi.org/10.5140/JASS.2026.43.3.129

The Soviet Luna program (1958–1976) conducted the first robotic lunar landings, rover traverses, and automated sample returns. This paper presents three major scientific outcomes from Luna missions: depth dependent regolith coarsening (70 → 130 μm) and densification (0.8 → 1.2 g/cm³), lateral geochemical gradients across mare-highland boundaries, and localized impact-generated magnetic anomalies (20–30 nT). Comparison with Apollo data shows broad agreement, with differences due to landing site geology and instrument characteristics. ...

Observation of the 19 January 2026 Forbush Decrease with the Geochang Neutron Monitor: Comparison with the Global Neutron Monitor Network

Jongil Jung, Young-Sil Kwak, Jongdae Sohn, Suyeon Oh, Yu Yi, Tae-Yong Yang, Paul Evenson

J. Astron. Space Sci. 2026;43(3):147-155.
https://doi.org/10.5140/JASS.2026.43.3.147

We analyzed the Forbush decrease (FD) on 19 January 2026 using data from the Geochang neutron monitor (GCHN) in Korea together with observations from 16 additional neutron monitor stations spanning a wide range of latitudes. The event was associated with a coronal mass ejection (CME)-driven interplanetary shock related to the X1.9 solar flare of 18 January 2026. The selected neutron monitor network observed a clear decrease in cosmic ray intensity following the shock arrival, and GCHN recorded a distinct FD signature with a minimum galactic cos...

ShadowCam Establishes Faustini’s Ancient Age

Barbara Giuri, Carolyn H. van der Bogert, Mark Robinson

J. Astron. Space Sci. 2026;43(3):157-167.
https://doi.org/10.5140/JASS.2026.43.3.157

ShadowCam is a NASA-funded imaging experiment onboard the Korea Pathfinder Lunar Orbiter (also known as Danuri), providing high-resolution (2 m/pixel) images of permanently shadowed regions (PSRs), enabling investigations into the distribution and accessibility of water ice and other volatiles necessary for future human exploration. Here, we use a ShadowCam image mosaic to revisit the crater-size frequency distribution (CSFD) of Faustini crater floor, the third-largest PSR, and of high cold-trapping potential. We find that all count areas exhib...

First Wind Measurements from a Fabry-Perot Interferometer at Bohyunsan Optical Astronomy Observatory, Korea

Jaewook Lee, Tae-Yong Yang, Young-Sil Kwak, Jeong-Heon Kim, Jongil Jung, Changsup Lee, Devin Wyatt, Katherine Herrera, Trond S. Trondsen

J. Astron. Space Sci. 2026;43(3):169-180.
https://doi.org/10.5140/JASS.2026.43.3.169

We present the first measurements from a Fabry-Perot interferometer (FPI) installed at Bohyunsan Optical Astronomy Observatory (BOAO) in Korea. The instrument, referred to as BHO-FPI, has been operated by the Korea Astronomy and Space Science Institute (KASI) since January 2025. BHO-FPI observes OI 557.7 nm, OI 630.0 nm, and OH 892.0 nm airglow emissions to estimate nighttime neutral winds from Doppler shifts in interference ring patterns. We describe the instrument configuration, data quality information, and initial wind observations from Jan...
