The Serra da Cangalha astrobleme as revealed by ASTER and SRTM orbital data.

This article focuses on the Serra da Cangalha astrobleme. Structural features caused by the impact of celestial bodies at the surface of the Earth always stir scientific interest. These impacts instantaneously release huge quantities of kinetic energy that depends only on the mass and the velocity of the cosmic body. The Serra da Cangalha astrobleme is the best preserved impact crater found in Brazil, as depicted by two modern sources of orbital remote sensing data: multispectral images acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer, and terrain elevation data collected by the Shuttle Radar Topographic Mission.
