Do you have a personal vision of the future? You may have a chance to give it three-dimensional form.

Last November, a nonprofit group called the Museum of Science Fiction announced plans to open a facility of that name in or near Washington by 2017. One step toward that goal was establishing a “preview museum” that would give the project — which lists its address as “Washington, D.C.; USA; Earth: Sol: Milky Way” — an actual presence. It would also provide a place to test ideas for the visitor experience and to hold fundraising events.

Now the group has announced a competition open to students, architects, industrial designers and exhibit designers, to design the preview museum. The specs: The facility should be 3,000 to 4,000 square feet and capable of housing at least seven interactive exhibits at a time. The gallery should also be able to accommodate special programs with seating for 150 people.

Earlier announcements from the group emphasized the museum’s commitment to boosting STEM (science, technology, engineering and mathematics) education, and reported promises of loans including models of the Enterprise E and Deep Space 9 vehicles used in “Star Trek” films, as well as hundreds of interviews with fabled sci-fi authors such as Ray Bradbury and Arthur C. Clarke.

The registration deadline is Oct. 31; submission deadline is Nov. 30; and the winner will be notified by Dec. 15. Information can be found at
