Artwork commemorating the “War of the Worlds” broadcast can be found in West Windsor.

A celebration of the 80th anniversary of the 1938 War of the Worlds broadcast and Martian “invasion” is in full launch mode for the end of this month.

The mARTian Weekend+ event, coordinated by West Windsor Arts Council, runs from Oct. 26 through the actual anniversary on Oct. 30.

“It’s part of our country’s history and unique to this place,” says Aylin Green, WWAC executive director. “We can look forward to celebrating the 90th anniversary and the 100th.”

Activities are free and spread throughout various area venues. They include art, parties, an Orson Welles séance, a re-enactment of the radio broadcast and more.

The West Windsor Farmers Market at the Princeton Junction train station plays host to the first major event on Saturday, Oct. 27, from 9 a.m. to 1 p.m. with a number of War of the Worlds-related activities.

Create a “Gourd”-geous alien to decorate home for Hallowe’en or welcome trick-or-treaters, or take part in the “Out of this World” Sidewalk Chalk Contest, open to individuals and groups of all ages, and professional artists. Designs must be original, inspired by space exploration, extraterrestrial life, or War of the Worlds.

More than $1,000 in gift cards and prizes, including a $300 Amazon gift card.

In addition to the monument in Van Nest Park that was installed for the 50th anniversary in 1988, the WWAC is emphasizing the “art” in an initiative called the mARTian Project by establishing a township-wide collection of permanent Martian-themed outdoor sculptures, to be installed in the years ahead at well-trafficked locations within West Windsor.

The first mARTian Project piece, “Scoutship,” by Eric Schultz will be unveiled at the West Windsor Arts Center on Oct. 27 at 2 p.m. This will be followed by a lecture on Orson Welles by Al Nigrin, professor of cinema studies at Rutgers, at 3 p.m. A screening of The Suitor is at 3:30 p.m., and after a brief intermission, there will be a screening of the 1953 version of The War of the Worlds from 4:30 to 6 p.m.

Meanwhile, sculpture proposals are still being accepted. The mARTian Project is open to all sculptors at least 18 years of age, regardless of location.

Entries must be original work; of safe design and construction; feature “Martian-like images” or relate to the War of the Worlds. Go to westwindsorarts.org/the-martian-project for more information.
