Paris, Nov 22 : Scientists have used the European Space Agency’s (ESA’s) Mars Express to produce the first crude map of aurorae on Mars, which are a powerful tool with which scientists can investigate the composition and structure of the Red Planet’s atmosphere.
The aurorae on Mars were discovered in 2004 using the SPICAM ultraviolet and infrared atmospheric spectrometer on board Mars Express.
These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by crustal rocks on Mars.
They highlight a number of mysteries about the way Mars interacts with electrically charged particles originating from the Sun.
