We still don't know if there's life on mars, as David Bowie pondered on his classic 1971 tune. But the late icon's legacy may finally be drifting to the mysterious planet soon, as the U.K.'s Royal Mail sent 52 sets of commemorative Bowie stamps into the stratosphere on helium balloons. The number represents the artist's 52-year long recording career.

The move is a nod to Bowie's 1976 cult film The Man Who Fell to Earth, as the stamps will plummet to earth once the balloons burst in space. They were launched on Monday and plan to fall today (March 14). Fans will have a chance to win a commemorative set, which has 10 stamps apiece, if they predict where they will land. Each one features Bowie's album covers and tour photos.

The Royal Mail's contest website shows video footage from the balloons (they're all attached with cameras). The sets reportedly reached 34,100m at a speed of about 12mph. After the balloons burst, the stamps will descend at nearly 200mph. They will slow to around 8mph by the time they hit the ground. If you'd like to enter to win the limited stamps, follow them on social media to find the clues. The contest ends on March 26.

The Bowie stamps were first created to honor the one-year anniversary of his death at age 69. Below, watch Duran Duran's Simon Le Bon recall a David Bowie memory at BRIT Awards 2016:
