However exciting space travel sounds, astronauts must still suffer with bad food. Now, food in space has to be dehydrated(使脱水)or pre-cooked and stored. This means astronauts aren't really eating fresh food.
New technology may change this. Scientific American reports that a specially-designed oven will be sent into space this autumn with NASA's NG-12 cargo(货物).Far from the common vacuum-packed(真空包装的)meals, astronauts may get to enjoy freshly baked cookies before the end of 2019.
Why aren't they baking cookies in space already?
For one thing, there's the risk of a fire. Engineers also have to overcome the challenge of microgravity, which prevents heat from circling inside ovens the same way it does on Earth.
Astronauts will still have to wait a while before they can have their cookies, though. After baking, the results will be sent back to Earth for safety testing. If successful, this will be the first oven to bake food in space.
“I believe…that will be game-changing for both science and astronauts, ”food technology researcher Maeena Naman Shafiee told Scientific American.
One of the main driving forces behind this project has been NASA's 2018 research into the effects of " confinement(封闭)and isolation(隔离)”. Unlike on the International Space Station(ISS), astronauts traveling out of Earth's orbit may not be able to speak to their loved ones on future missions, which could lead to negative feelings.
It's hoped that the chance to bake and sense familiar smells can bring joy to crews(宇航人员).
“Is the ISS going to smell like fresh-baked cookies? We don't know, ”said NanoRacks' communications manager Abby Dickes. “But that's a feeling we all know and love…that will make someone feel at home.”
Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel. Astronauts have already grown plants aboard the ISS.
With commercial(商业的)space travel now being planned, who knows what other developments may surprise us in the future

Do you like spicy(辛辣的) food? If yes, try this spicy food by Emily Rudnick. She is a twelve-year-old girl at Aspen Middle School in Denver, US. She made her own spicy food. It is called Rudspice.
Rudnick learned to cook at an early age of five. The idea of spice came from a camp. She put a lot of spice on food. “The food is better. I think we should make a spice that can make all food taste better.” Rudnick told Denver Westward, a reporter from BBC.
She first learned about the spice business(生意) from Savory Spice owners Mike and Janet Johnston. Then she tried it at home. With the help of her father Mr. Rudnick, she made six different kinds of spicy food. To get the best one, she tested their tastes on foods like popcorn(爆米花) and eggs. She used chili(辣椒), onions and other things to make Rudspice.
She made it into a business, too. This month, it went into Savory Spice shops in the US.

At the beginning of human history, people took their food from the world around them. They ate all that they could find, and then moved on. About 10,000 years ago people started learning to farm (耕种).
People eat different food in different places. In China rice is the main food for people in the south and the people in the north eat noodles. People who live in European countries near the sea eat lots of fish. But in Central Europe, people are away from the sea. So they don’t eat so much fish. They eat more special meat instead.
People eat food with different tools (工具) in different places. In North America, Australia, and Europe, people eat with knives and forks. In China, people eat with chopsticks. In parts of India and the Middle East, people use their hands to pick up food.
Now people can eat different food from different places. Today it is possible that food is sent easily from one part of the world to another. We can almost eat whatever we like at any place of the world. For example, people in Britain can eat bananas from Africa and rice from India. Food is becoming a very big business now.
