New impact crater on Mars reveals darker material beneath reddish dust

LOS ANGELES: A new impact crater discovered on Mars reveals darker material beneath reddish dust, according to a latest photograph released by NASA's Jet Propulsion Laboratory (JPL).

The crater on the surface of Mars formed at most between September 2016 and February 2019, JPL said.

The material beneath the reddish dust looks blue, but is a false colored image, which combines several color filters to enhance differences between material compositions, JPL said.

The light blue indicates an absence of brighter, redder dust where the impact blast scoured the surface, revealing bedrock below. The very bright blue could be ejecta with a different composition that was thrown by the impact, according to JPL.

The picture was taken by High Resolution Imaging Science Experiment, a camera on board the Mars Reconnaissance Orbiter. Xinhua
