“…(3200) Phaethon, the target of the DESTINY + Mission 38 , also exhibits blue spectra in the visible wavelength range and turn-up in the UV. Recently, many ground-based observations were made over a wide wavelength range, which reported that the variation in visible spectral slope depends on rotational phase.…”

Ryugu is a carbonaceous rubble-pile asteroid visited by the Hayabusa2 spacecraft. Small rubble pile asteroids record the thermal evolution of their much larger parent bodies. However, recent space weathering and/or solar heating create ambiguities between the uppermost layer observable by remote-sensing and the pristine material from the parent body. Hayabusa2 remote-sensing observations find that on the asteroid (162173) Ryugu both north and south pole regions preserve the material least processed by space weathering, which is spectrally blue carbonaceous chondritic material with a 0–3% deep 0.7-µm band absorption, indicative of Fe-bearing phyllosilicates. Here we report that spectrally blue Ryugu’s parent body experienced intensive aqueous alteration and subsequent thermal metamorphism at 570–670 K (300–400 °C), suggesting that Ryugu’s parent body was heated by radioactive decay of short-lived radionuclides possibly because of its early formation 2–2.5 Ma. The samples being brought to Earth by Hayabusa2 will give us our first insights into this epoch in solar system history.

“…bombarding interplanetary dust particles. This is the case for the asteroid 3200 Phaethon , the target of the upcoming DESTINY + JAXA mission (Sarli et al 2018), which will carry a dust detector capable of chemical composition analysis (Krüger et al 2019).…”

This manuscript represents a review on progress made over the past decade concerning our understanding of meteoroid bombardment on airless solar system bodies as one of the sources of the formation of their exospheres. Specifically, observations at Mercury by MESSENGER and at the Moon by LADEE, together with progress made in dynamical models of the meteoroid environment in the inner solar system, offer new tools to explore in detail the physical phenomena involved in this complex relationship. This progress is timely given the expected results during the next decade that will be provided by new missions such as DESTINY+, BepiColombo, the Artemis program or the Lunar Gateway.

“…The limit to optical depth of a Phaethon's trail is ≤ 3×10 −9 (Jewitt et al, 2018), consistent with those of cometary dust trails (10 −9 -10 −8 , from Sykes and Walker, 1992;Ishiguro et al, 2009) (see also section 8.6.3). While continued long wavelength observations of Phaethon to detect large particles will be helpful (Jewitt et al, 2015), the true nature of Phaethon and the PGC complex objects may await spacecraft missions resembling NASA's "Deep Impact" (A'Hearn et al, 2005;Kasuga et al, , 2007a) and JAXA's "DESTINY+" (Sarli et al, 2018).…”
