The Mars Society is thrilled to announce our annual poster design contest—and we’re calling on all creative minds! If you have a passion for graphic design and a love for Mars and space exploration, this is your chance to make your mark.
The winning poster will be featured as the main promotional graphic for our 28th Annual International Mars Society Convention, set for October 9–11, 2025 at the University of Southern California in Los Angeles.

This year’s convention theme, “Mars: The Time Has Come!”, perfectly echoes the U.S. government’s recent push toward making a near-term human mission to Mars a central goal of America’s space program.
To enter, simply create a poster that embodies this theme and send your submission to postercontest@marssociety.org by Friday, May 16th at 5:00 pm MT. Feel free to email any questions about the contest to the same address.
Technical requirements for the artwork are as follows: 1) The poster size should be 11″ x 17″, 2) There are no restrictions with regard to use of color, 3) If your poster is selected, the designer will need to submit a full color poster as well as a gray-scale copy, and 4) Poster designs can be submitted in Photoshop or as a .pdf file (the former is preferred).
The Mars Society will announce the winning design during the week of May 26th. We can’t wait to see your out-of-this-world creations. Good luck!
