In-situ wavelength calibration without a calibration target: use of Fraunhofer lines after landing on planetary surface

Autor: Mori, Shoki, Boettger, Ute, Buder, Maximilian, Cho, Yuichiro, Dietz, Enrico, Hagelschuer, Till, Hübers, Heinz-Wilhelm, Kameda, Shingo, Kopp, Emanuel, Prieto-Ballesteros, Olga, Rull, Fernando, Ryan, Conor, Schroeder, Susanne, Sugita, Seiji, Tabata, Haruhisa, Usui, Tomohiro, Yumoto, Koki

Accurate wavelength calibration is critical for qualitative and quantitative spectroscopic measurements. Many spectrometers for planetary exploration are equipped with onboard calibration sources. However, such calibration sources are not always avai

Report

Development of a multispectral stereo-camera system comparable to Hayabusa2 Optical Navigation Camera (ONC-T) for observing samples returned from asteroid (162173) Ryugu

Autor: Cho, Yuichiro, Yumoto, Koki, Yabe, Yuna, Mori, Shoki, Ogura, Jo A., Yada, Toru, Miyazaki, Akiko, Yogata, Kasumi, Hatakeda, Kentaro, Nishimura, Masahiro, Abe, Masanao, Usui, Tomohiro, Sugita, Seiji

Hayabusa2 collected 5.4 g of samples from the asteroid (162173) Ryugu and brought them back to Earth. Obtaining multiband images of these samples with the spectral bands comparable to those used for remote-sensing observations is important for charac
