First space-baked cookies took 2 hours in experimental oven

The results are finally in for the first chocolate chip cookie bake-off in space.

While looking more or less normal, the best cookies required two hours of baking time last month up at the International Space Station. It takes far less time on Earth, under 20 minutes. And how do they taste? No one knows.

Still sealed in individual baking pouches and packed in their spaceflight container, the cookies remain frozen in a Houston-area lab after splashing down two weeks ago in a SpaceX capsule.

They were the first food baked in space from raw ingredients. The makers of the oven expected a difference in baking time in space, but not that big.

“There’s still a lot to look into to figure out really what’s driving that difference, but definitely a cool result,” Mary Murphy, a manager for Texas-based Nanoracks, said this week. “Overall, I think it’s a pretty awesome first experiment.”

Located near NASA’s Johnson Space Center, Nanoracks designed and built the small electric test oven that was launched to the space station last November. Five frozen raw cookies were already up there.

Italian astronaut Luca Parmitano was the master baker in December, radioing down a description as he baked them one by one in the prototype Zero G Oven.

The first cookie — in the oven for 25 minutes at 300 degrees Fahrenheit (149 degrees Celsius) — ended up seriously under-baked. He more than doubled the baking time for the next two, and the results were still so-so.

The fourth cookie stayed in the oven for two hours, and finally success.

“So this time, I do see some browning,” Parmitano radioed. “I can’t tell you whether it’s cooked all the way or not, but it certainly doesn’t look like cookie dough anymore.”

Parmitano cranked the oven up to its maximum 325 degrees F (163 degrees C) for the fifth cookie and baked it for 130 minutes. He reported more success.

Additional testing is required to determine whether the three returned cookies are safe to eat.

Eating something other than dehydrated or prepackaged food will be particularly important as astronauts head back to the moon and on to Mars.
