Happy Birthday Mars Rover, written by Preston Choi
Directed by Kara Toll
Produced by Phillip Heflin
Performing June 19th – July 5th, 2026
Synopsis:
The Mars Rover sings Happy Birthday to itself as it searches for life on Mars as humans back on Earth search to understand what life is. A medley of snapshots, from cave people naming abstract concepts, bubbles that scream when popped, housewives battling existential dread, cows trying to get to heaven, and the last human on Earth collecting jars of hair. Happy Birthday Mars Rover is a darkly comedic and whimsically morbid attempt to understand the human condition and life itself.
