New York-based food company Retrofuture Products has re-launched Space Food Sticks, a snackfood first developed for early space missions.

Retrofuture president Eric Lefcowitz said he believed the product would catch on with a new generation of consumers. “We’re confident fans of the original will love the taste and we’re happy a whole new generation of Sticks fans will get an opportunity to find out about this unique treat,” Lefcowitz said.

The chocolate and peanut butter chewy snack was originally developed in the late-60s for NASA, and was marketed by Pillsbury as Space Food Sticks.

Retrofuture Products said it is exploring several avenues to sell the products, which come in bite-sized “portion control” pieces containing only 21 calories each, including museums, theme parks and nostalgia candy stores.
