About the Lab

Professor Ji-hyeong Park's research lab specializes in innovative space-based observation systems and Earth-observing technologies, focusing on advanced telescope designs using MEMS micromirrors for wide-field transient event detection and high-time-resolution imaging. The lab explores the intersection of planetary science, environmental monitoring, and socio-ecological systems, particularly through the lens of the Anthropocene, integrating geohistorical analysis with modern astrophysical observations. Research also includes mission design and orbital optimization for Earth-orbiting satellites, such as KAISTSAT-1, to enhance all-sky survey efficiency and mitigate space environment impacts like the South Atlantic Anomaly.

Obscura telescope with a MEMS micromirror array for space observation of transient luminous phenomena or fast-moving objects

We introduce a novel telescope consisting of a pinhole-like camera with rotatable MEMS micromirrors substituting for pinholes. The design is ideal for observations of transient luminous phenomena or fast-moving objects, such as upper atmospheric lightning and bright gamma ray bursts. The advantage of the MEMS "obscura telescope" over conventional cameras is that it is capable both of searching for events over a wide field of view, and fast zooming to allow detailed investigation of the structure

지구의 짐: 인류세 담론의 과학과 신화
박지형
탈경계인문학Trans-Humanities

최근의 인류세 논쟁은 인간을 지질학적 행위자로 인식하는 계기가 되었지만 역사적 배경과 정치적 함의에 대해 이견을 보이고 있다. 키플링의 제국주의를 모티브로 삼아 인류세의 시점과 시공간적 배경 및 정치적 함의를 초학제적으로 조망하고자 한다. 지질학자는 핵실험에서 유래한 방사능 같은 지층 기록과 인간 활동이 일치하는 시기를 찾지만, 인간 행위의 역사적 동인과 변동을 파악하지 못한다. 키플링의 미국 서부 여행지는 신의 소명을 실천한다는‘ 백인의 짐’이 자연과 인간을 자본 축적의 도구로 전락시킨‘ 문명의 짐’이자 지속가능성을 위협하는‘ 지구의 짐’으로 진화하는 과정을 보여준다. 지구가 상품화할 수 없는 커먼즈라는 인식을 공유하고‘ 생태적 부채’를 청산하는 정치적 해법을 모색해야‘ 포스트-인류세’를 상상할수 있다.

Exposure Time Analysis for Far-Ultraviolet Imaging Spectrograph All-Sky Survey Mission

Global exposure time distribution through all-sky survey, one of main science missions of KAISTSAT-1, has been simulated. Exposure time distribution has its minimum on the celestial equator and increases with moving to polar regions according to the present mission operation scenario. SAA (South Atlantic Anomaly) and the moon can make further decreases of exposure time around the celestial equator. Effects of SAA on all-sky survey exposure time can be compensated with a simple observational sche
