Space Science Reviews 220(1) 2024年1月24日 査読有りAbstract Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the exploration of a little-processed long-period comet, possibly entering the inner Solar System for the first time, or to encounter an interstellar object originating at another star. The objectives of the mission are to address the following questions: What are the surface composition, shape, morphology, and structure of the target object? What is the composition of the gas and dust in the coma, its connection to the nucleus, and the nature of its interaction with the solar wind? The mission was proposed to the European Space Agency in 2018, and formally adopted by the agency in June 2022, for launch in 2029 together with the Ariel mission. Comet Interceptor will take advantage of the opportunity presented by ESA’s F-Class call for fast, flexible, low-cost missions to which it was proposed. The call required a launch to a halo orbit around the Sun-Earth L2 point. The mission can take advantage of this placement to wait for the discovery of a suitable comet reachable with its minimum $\varDelta $V capability of $600\text{ ms}^{-1}$. Comet Interceptor will be unique in encountering and studying, at a nominal closest approach distance of 1000 km, a comet that represents a near-pristine sample of material from the formation of the Solar System. It will also add a capability that no previous cometary mission has had, which is to deploy two sub-probes – B1, provided by the Japanese space agency, JAXA, and B2 – that will follow different trajectories through the coma. While the main probe passes at a nominal 1000 km distance, probes B1 and B2 will follow different chords through the coma at distances of 850 km and 400 km, respectively. The result will be unique, simultaneous, spatially resolved information of the 3-dimensional properties of the target comet and its interaction with the space environment. We present the mission’s science background leading to these objectives, as well as an overview of the scientific instruments, mission design, and schedule.

Journal of Evolving Space Activities 2 n/a 2024年The University of Tokyo and Arkedge Space Inc. are now developing 6U CubeSat named ONGLAISAT in collaboration with TASA (ex-NSPO), whose main mission is Earth remote sensing. This satellite uses S-band for telemetry and command communication by 10-100 kbps and 4 kbps for each link, and X-band for mission data transfer at high speed by 36 Mbps at maximum. Moreover, it has a Store & Forward (S&F) system for one of the missions. In this paper, we summarize the communication system of ONGLAISAT which consists of the S-band, X-band, and S&F components. In particular, we discuss the benefit of installing the S&F devices as a (compact) back-up TT&C system for a CubeSat.

Journal of Evolving Space Activities 2 n/a 2024年Comet Interceptor is ESA's F-class mission to explore a long-period comet. Comet Interceptor performs a flyby observation with 3 spacecraft: 1 main spacecraft (spacecraft A) and 2 small probes (probe B1 and probe B2). JAXA will provide one of the small probes, probe B1, taking advantage of its past achievements in micro spacecraft. The probe B1 is a micro spacecraft weighing about 35 kg. The bus size is about 24U, and the envelope including protrusions is about 50 cm cubic. This probe will carry three types of science instruments for complementary observations with ESA's instruments onboard the main spacecraft and another small probe at multiple points. The first instrument is a wide-angle camera and a narrow-angle camera (WAC/NAC) for optical observations of the nucleus. The second is Hydrogen Lyman-alpha Imager (HI) to observe a Lyman-alpha of coma, and the third is a Plasma Suite (PS) to observe plasma using an ion sensor and a magnetometer. The probe B1 performs a flyby observation without any commands from the ground, considering dust impacts during the closest approach to the comet. This paper presents the result of conceptual design for the small probe under severe constraints and its future challenges.
