    <jats:title>Abstract</jats:title> <jats:p>We present a detection of a bright burst from the fast radio burst (FRB) 20201124A, which is one of the most active repeating FRBs, based on S-band observations with the 64 m radio telescope at the Usuda Deep Space Center/JAXA. This is the first FRB observed by using a Japanese facility. Our detection at 2 GHz in 2022 February is the highest frequency for this FRB and the fluence of &amp;gt;189 Jy ms is one of the brightest bursts from this FRB source. We place an upper limit on the spectral index α = −2.14 from the detection of the S band and non-detection of the X band at the same time. We compare the event rate of the detected burst with those from previous research and suggest that the power law of the luminosity function might be broken at lower fluence and the fluences of bright FRBs are distributed up to over 2 GHz with the power law against frequency. In addition, we show that the energy density of the burst detected in this work is comparable to the bright population of one-off FRBs. We propose that repeating FRBs can be as bright as one-off FRBs and only their brightest bursts might be detected, so some repeating FRBs intrinsically might have been classified as one-off FRBs.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>C-type asteroids<jats:sup>1</jats:sup> are considered to be primitive small Solar System bodies enriched in water and organics, providing clues to the origin and evolution of the Solar System and the building blocks of life. C-type asteroid 162173 Ryugu has been characterized by remote sensing<jats:sup>2–7</jats:sup> and on-asteroid measurements<jats:sup>8,9</jats:sup> with Hayabusa2 (ref. <jats:sup>10</jats:sup>). However, the ground truth provided by laboratory analysis of returned samples is invaluable to determine the fine properties of asteroids and other planetary bodies. We report preliminary results of analyses on returned samples from Ryugu of the particle size distribution, density and porosity, spectral properties and textural properties, and the results of a search for Ca–Al-rich inclusions (CAIs) and chondrules. The bulk sample mainly consists of rugged and smooth particles of millimetre to submillimetre size, confirming that the physical and chemical properties were not altered during the return from the asteroid. The power index of its size distribution is shallower than that of the surface boulder observed on Ryugu<jats:sup>11</jats:sup>, indicating differences in the returned Ryugu samples. The average of the estimated bulk densities of Ryugu sample particles is 1,282 ± 231 kg m<jats:sup>−3</jats:sup>, which is lower than that of meteorites<jats:sup>12</jats:sup>, suggesting a high microporosity down to the millimetre scale, extending centimetre-scale estimates from thermal measurements<jats:sup>5,9</jats:sup>. The extremely dark optical to near-infrared reflectance and spectral profile with weak absorptions at 2.7 and 3.4 μm imply a carbonaceous composition with indigenous aqueous alteration, matching the global average of Ryugu<jats:sup>3,4</jats:sup> and confirming that the sample is representative of the asteroid. Together with the absence of submillimetre CAIs and chondrules, these features indicate that Ryugu is most similar to CI chondrites but has lower albedo, higher porosity and more fragile characteristics.</jats:p>

    <p>Hayabusa2 is a Japanese sample return mission from the asteroid Ryugu. The Hayabusa2 spacecraft was launched on 3 December 2014, arrived at Ryugu on 27 June 2018. It will stay in proximity of Ryugu until December 2019 for in situ observation and soil sample collection aiming to return to the Earth in December 2020 with the collected sample. During the 1.5-year asteroid proximity operation, the spacecraft performs several numbers of descent operation to deploy and land rovers, and to touchdown collecting soil sample. To obtain large amount of various data during asteroid proximity operation, data downlink from Hayabusa2 is realized using two high gain antennas (HGAs) which are designated to X-band (8GHz) downlink and Ka-band (32GHz) downlink respectively. This paper summarizes Ka-band capability of Hayabusa2 and its contribution to asteroid proximity operation including the Landing Site Selection (LSS) activity. Also, feedbacks for Ka-band equipped future deep space mission are extracted based on the comparison between X/Ka-band operation results.</p>
