농촌진흥청 국립원예특작과학원에서는 2021년 분홍색계 소 형 호접란 ‘Arihong’을 육성하였다. 2014년 밝은 분홍색 소형 품종 Phalaenopsis ‘Wedding’와 백색 바탕에 분홍빛을 가지는 소형종 P. ‘[{KT1398-1×(KM-6)-4}×Chiangbeauty-88]-23’ 를 모본과 부본으로 교배하였다. 2018년 실생 120개체 중 잎자세, 화색, 화형, 꽃대수 등 특성이 우수한 ‘14104-1’ 개체를 선발하여 기내 화경배양을 통해 증식하였다. 2018년부터 2021년에까지 1차, 2차특성검정을 통해 품종의 안정성과 균일성을 확인한 후 ‘Arihong’로 명명하였다. 이 품종은 백색(WG155B) 바탕에 중앙 에는 보라빛 분홍색(PVG80B)을 띄며, 진한 자주색(PG78A) 순판 을 가지는 것이 특징이다. 꽃대가 2대씩 발생하고 꽃대 길이는 평균 42.1cm 소형 분화로 적절한 크기를 가지고 있다. 평피기 형태의 꽃은 길이와 폭이 각각 5.1, 5.7cm이며, 분지가 발생하여 1개의 꽃대에 13.0개의 소화가 착생한다. ‘Arihong’의 잎은 수평으로 자라며 길이와 폭이 각각 13.0cm, 4.9cm였다. 또한 초세가 우수하고 생육 속도가 빨라 엽수 확보가 용이한 특성을 보였다.

We present a novel method that can enhance the detection success rate of interstellar objects. Interstellarobjects are objects that are not gravitationally bound to our solar system and thus are believed to haveoriginated from other planetary systems. Since the nding of two interstellar objects, 1l/`Oumuamua in2017 and 2l/Borisov in 2019, much attention has been paid to nding new interstellar objects. In thispaper, we propose the use of Heliospheric Imagers (HIs) for the survey of interstellar objects. In particular,we show HI data taken from Solar TErrestrial RElation Observatory/Sun Earth Connection Coronal andHeliospheric Investigation and demonstrate their ability to detect `Oumuamua-like interstellar objects. HIs are designed to monitor and study space weather by observing the solar wind traveling throughinterplanetary space. HIs provide the day-side observations and thus it can dramatically enlarge theobservable sky range when combined with the traditional night-side observations. In this paper, we rstreview previous methods for detecting interstellar objects and demonstrate that HIs can be used for thesurvey of interstellar objects.

Since interstellar objects like 1I/`Oumuamua and 2I/Borisov originate from exoplanetary systems, evenif we do not visit the exoplanetary systems,yby, rendezvous, and sample return missions of interstellarobjects can provide clues to solve the mysteries of cosmic life phenomena such as the origin of exoplanetarysystems, galactic evolution, biosignatures (or even technosignatures), and panspermia. In this paper, wereview space missions for interstellar object exploration in the stage of mission design or concept studysuch as Project Lyra, Bridge, Comet Interceptors, and LightcraftTM. We also review space missions,OSIRIS-REx and NEA Scout, designed for Near Earth Asteroids(NEA) explorations, to investigate thecurrent state of basic technologies that can be extended to explore interstellar objects in a velocity of~ 6AU/year. One of the technologies that needs to be developed for interstellar object exploration is aspacecraft propulsion method such as solar sail, which can catch up with the fast speed of interstellarobjects. If this kind of propulsion becomes practical for space explorations, interstellar object explorationswill mark a new era and serve as a driving force to provide evidences of cosmic life.
