ESA Mars Express Audio recording: MSL Broadcasts the sounds of an alien descent

While no human ‘heard’ NASA's Curiosity arrive at Mars this morning, the radio signals transmitted during descent and recorded by Mars Express have been processed and shifted into human-audible frequencies.

This provides a faithful reproduction of the ‘sound’ of the NASA mission’s arrival at Mars and its seven-minute plunge to the Red Planet’s surface.
