Mission Name: MASCOT


The MAScot CAMera (MASCAM) is a wide-angle camera that operates as both a descent and in-situ imager. MASCAM will provide ground truth for measurements acquired by the Hayabusa2 orbiter instruments and the in-situ MASCOT sensor suite as well as contextual information of the undisturbed sampling sites on the surface of asteroid 162173 Ryugu. Images taken at different sun angles during the surface phase will contribute to the time-dependent photometric measurements of the regolith.

MASCAM utilizes a 1024 × 1024 pixel radiation-tolerant Complementary Metal-Oxide-Semiconductor (CMOS) image sensor with a wavelength range of 400 - 1000 nm, peaking at 600 - 700 nm. A focal length of 14.8 mm provides a nominal ground resolution of 150 micron per pixel at a distance of 150 mm. During asteroid daytime, MASCAM performs panchromatic imaging. At night, the camera performs color imaging by using four light emitting diode (LED) devices centered at 470 nm (blue), 530 nm (green), 640 nm (red), and 805 nm (near-infrared) to illuminate the near field of the surface. The MASCAM is mounted inside the payload compartment of the MASCOT lander.
