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 any more.”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.As for aroma, the astronauts could smell the cookies when they removed them from the oven, except for the first.That’s the beauty of baking in space, according to former NASA astronaut Mike Massimino. He now teaches at Columbia University and is a paid spokesman for DoubleTree by Hilton. The hotel chain provided the cookie dough, the same kind used for cookies offered to hotel guests. It’s offering one of the space-baked cookies to the Smithsonian Institution’s National Air and Space Museum for display.“The reminder of home, the connection with home, I think, can’t be overstated,” Massimino said. “From my personal experience ... food is pretty important for not just nutrition but also for morale in keeping people connected to their home and their Earth.”Eating something other than dehydrated or prepackaged food will be particularly important as astronauts head back to the moon and on to Mars.Nanoracks and Zero G Kitchen, a New York City startup that collaborated with the experiment, are considering more experiments for the orbiting oven and possibly more space appliances. What’s in orbit now are essentially food warmers.There’s an added bonus of having freshly baked cookies in space.“We made space cookies and milk for Santa this year,” NASA astronaut Christina Koch tweeted.___The Associated Press Health and Science Department receives 3315

The White House is planning a flyover of two F-35 fighter jets during Wednesday's visit from Polish President Andrzej Duda, according to three US government officials.The flyover above the White House South Lawn comes as the two governments are preparing to announce an increase in the US troop presence in Poland. US officials on Tuesday previewed a "significant announcement" on US troop presence in Poland when Duda visits the White House.Poland is also taking steps to purchase new F-35s from the United States, and the country's defense minister traveled to Eglin Air Force Base in Florida this week to see the jets in action.Asked about the prospect of a flyover on Wednesday, a White House spokesman said there was "nothing to announce right now."Last week, President Donald Trump marveled at multiple flyovers during his visit to Europe, including at D-Day commemoration ceremonies in Portsmouth, England, and on France's Normandy coast.He is known to revel in the military trappings of his job. But a flyover of military aircraft at the White House is exceedingly rare.Senior administration officials refused on a briefing call to get into details of the troop announcement on Tuesday, but Polish officials have said this week that the announcement is related to increasing the levels of permanent US troops stationed in Poland.A US defense official said the two leaders will sign a joint political declaration with a broad-strokes military component that calls for about 1,000 additional US troops to go to Poland on a rotational basis. Many of the troops will rotate to other exercise and training locations in Europe.Poland has termed the new US troop presence "Fort Trump," though it's not clear whether that will be its official name.Currently there are around 4,000 US troops in Poland on a rotational basis.The senior administration officials said the declaration would significantly enhance US-Poland military-to-military relationships. The officials said it would be in compliance with the NATO-Russia Founding Act, which guides relations between NATO and Russia. 2093

  

This story will be updated to reflect updated travel information. Air travel could be snarled heading into Thanksgiving thanks to a large snowstorm poised to sweep across the country on Tuesday and Wednesday. As a result, United and Delta have both announced waivers for some travelers impacted by this week's storm. The waivers allow travelers to rebook their flight without penalty. Adding insult to injury, a second storm could toil with travelers following the holiday. According to the National Weather Service, nearly a foot of snow is expected to fall in Denver, which is a major hub for United Airlines. The National Weather Service also cautioned drivers who will use Interstates 70, 26 and 76. United Airlines announced on Sunday travel waivers for those departing from Denver now through Nov. 29. The pre-Thanksgiving storm is then expected to travel north, where 5-7 inches of snow are expected around Minneapolis. Minneapolis is a major hub for Delta. Delta announced late Monday waivers for those flying out of Minneapolis.Although snow is expected to stay well to the north and west, Chicago, Indianapolis, Detroit and Cincinnati are expecting an extreme wind event. Much of the Midwest was placed under a high wind watch for Wednesday. Another storm is expected to sweep across the Rockies and Upper Midwest on Friday and Saturday, but it is too early to predict the amount of snow. 1411
