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 space science and space application fields in Korea. JASS is an international journal devoted to the publication of fundamental and applied investigations of all aspects of space-related 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, full texts of articles are free for all users to read and use. The papers published in JASS are accessible at the journal homepage (http://janss.kr), DOAJ website as well as at the SAO/NASA ADS website. JASS has been indexed by KCI and SCOPUS since 2007 and 2012, respectively. Also, JASS was re-indexed by DOAJ and newly indexed as 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).

Uncertainty Quantification of Thermophysical Property Measurement in Space and on Earth: A Study of Liquid Platinum Using Electrostatic Levitation

Jannatun Nawer, Takehiko Ishikawa, Hirohisa Oda, Chihiro Koyama, Douglas M. Matson

J. Astron. Space Sci. 2023;40(3):93-100.
https://doi.org/10.5140/JASS.2023.40.3.93

A study of uncertainty analysis was conducted on four key thermophysical properties of molten Platinum using a non-contacting levitation technique. More specifically, this work demonstrates a detailed reporting of the uncertainties associated with the density, volumetric thermal expansion coefficient, surface tension and viscosity measurements at higher temperatures for a widely used refractory metal, Platinum using electrostatic levitation (ESL). The microgravity experiments were conducted using JAXA’s Electrostatic Levitation Furnace (ELF) ...

Polar Mesospheric Summer Echo Characteristics in Magnetic Local Time and Height Profiles

Young-Sook Lee, Ram Singh, Geonhwa Jee, Young-Sil Kwak, Yong Ha Kim

J. Astron. Space Sci. 2023;40(3):101-111.
https://doi.org/10.5140/JASS.2023.40.3.101

We conducted a statistical study of polar mesospheric summer echoes (PMSEs) in relation to magnetic local time (MLT), considering the geomagnetic conditions using the K-index (or K). Additionally, we performed a case study to examine the velocity profile, specifically for high velocities (≥ ~100 m/s) varying with high temporal resolution at high K-index values. This study utilized the PMSE data obtained from the mesosphere–stratosphere–troposphere radar located in Esrange, Sweden (63.7°N, 21°E). The change in K-index in terms of MLT wa...

Studying the Ephemeris Effect on Position Accuracy Based on Criteria Applied to Baseline Lengths by New MATLAB Program (NMP)

Shimaa Farouk, Mahmoud El-Nokrashy, Ahmed Abd-Elhay, Nasr Saba

J. Astron. Space Sci. 2023;40(3):113-122.
https://doi.org/10.5140/JASS.2023.40.3.113

Although the Relative Global Navigation Satellite System (GNSS) positioning technique provides high accuracy, it has several drawbacks. The scarcity of control points, the long baselines, and using of ultra-rabid and rabid products increased position errors. This study has designed a New MATLAB Program that helps users automatically select suitable IGS stations related to the baseline lengths and the azimuth between GNSS points and IGS stations. This study presented criteria for the length of the baselines used in Egypt and an advanced estimate...

Post Trajectory Insertion Performance Analysis of Korea Pathfinder Lunar Orbiter Using SpaceX Falcon 9

Young-Joo Song, Jonghee Bae, SeungBum Hong, Jun Bang, Donghun Lee

J. Astron. Space Sci. 2023;40(3):123-129.
https://doi.org/10.5140/JASS.2023.40.3.123

This paper presents an analysis of the trans-lunar trajectory insertion performance of the Korea Pathfinder Lunar Orbiter (KPLO), the first lunar exploration spacecraft of the Republic of Korea. The successful launch conducted on August 4, 2022 (UTC), utilized the SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station. The trans-lunar trajectory insertion performance plays a crucial role in ensuring the overall mission success by directly influencing the spacecraft’s onboard fuel consumption. Following separation from the launch vehic...
