DESTINY+ (Demonstration and Experiment of Space Technology for INterplanetary voYage with Phaethon fLyby and dUst Science) was selected in 2017 as a mission for JAXA/ISAS small class program. It will be launched in 2024 by an Epsilon S rocket and fly by an asteroid (3200) Phaethon in January 2028. It is a joint mission of technology demonstration and scientific observation. Engineering challenges include an up-close encounter at a distance of 500 km from Phaethon with radio-optical hybrid navigation guidance and control and autonomous imaging based on optical information for target tracking during a high-speed flyby of about 35km/sec. The science goal is to understand the nature and origin of cosmic dust particles brought onto the Earth and their parent bodies. Phaethon is a parent body of the Geminid meteor shower. The science objectives are two folded: (1) in situ analyses of velocity, arrival direction, mass and chemical composition of interplanetary and interstellar dust particles around 1 au, the dust trail, and nearby Phaethon, and (2) flyby imaging of Phaethon to study its geology, for understanding dust ejection mechanism of an active asteroid and the surface feature and composition which are affected by extensive solar heating. Science payloads include a panchromatic, telescopic camera with a tracking capability (TCAP), a visible-NIR multi-band camera (MCAP), and a dust analyzer (DDA), which is an upgrade version of Cassini Cosmic Dust Analyzer (CDA). While the two cameras are developed by PERC/Chitech, DDA is developed by Univ. of Stuttgart, as an international collaboration with DLR. An international observation campaign for Phaethon was conducted in December 2017 and that for stellar occultation by Phaethon was performed in 2019, to better characterize Phaethon. Here, we present the current status and science of DESTINY+. 

About Tomoko Arai
 
 
Dr. Tomoko Arai is a Principal Staff Scientist of Planetary Exploration Research Center (PERC) at Chiba Institute of Technology (ChiTech), Japan. She is currently serving as the Principal Investigator of JAXA’s DESTINY+ mission. Her research areas include mineralogy, petrology, geochemistry, and reflectance spectroscopy of lunar and planetary materials. After receiving her Ph.D. from the University of Tokyo in 1998, she joined JAXA working for the development of the International Space Station (ISS) and their science payloads and later the Kaguya (SELENE) lunar mission. She moved to the National Institute of Polar Research as a postdoctoral researcher in 2004 and The University Museum, The University of Tokyo in 2009. She joined PERC, Chitech in 2009 and has been there since then. She led the ISS METEOR project, which conducted meteor observation on board the ISS from 2016 to 2019. She participated in ANSMET, the Antarctic Search for Meteorites in the 2012-2013 field season. Asteroid 22106 Tomokoarai (2000 NC12) was named in her honor.
