Mythodea — Music for the NASA Mission: 2001 Mars Odyssey is a choral symphony by Greek electronic composer and artist Vangelis. It premiered as a single concert in Athens, Greece, in 1993 but a recording was only released in 2001 by Vangelis' then new record label Sony Classical, which also set up the NASA connection and promoted a new concert, this time with a worldwide audience.

Evangelos Odysseas Papathanassiou, known professionally as Vangelis, was a Greek keyboardist, composer, and producer of electronic, progressive, ambient, and classical orchestral music. He composed the Academy Award-winning score to Chariots of Fire (1981), as well as for the films Blade Runner (1982), Missing (1982), Antarctica (1983), The Bounty (1984), 1492: Conquest of Paradise (1992), and Alexander (2004), and the 1980 PBS documentary series Cosmos: A Personal Voyage by Carl Sagan.
