China's Moon Plants Are Already Dead

China's Moon Plants Are Already Dead The cotton seeds were the first living material that humans have grown on another world.

The growing of plants in outer space has elicited much scientific interest. In the late 20th and 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but

Space - grown plants could also supplement astronauts’ packaged diet with fresh nutritious produce. Knowing how to grow plants in confined spaces isn’t just of benefit to salad-craving astronauts. Recent space -gardening experiments on the ISS have taken place using a plant - growing system

A land of unrelenting wind and ice, Antarctica is about as far from verdant as any place can get. Yet cucumbers are growing on the continent’s coast. Next to them, bunches of leafy swiss chard, fresh herbs, and peppery arugula thrive.

These greenhouse vegetables are the stars of one of several scientific projects underway at Neumayer Station III, the third iteration of a German research facility run by the polar science-focused Alfred Wegener Institute. The greenhouse’s primary purpose is pretty lofty: It’s a laboratory for studying how to grow food in outer space. Specifically, the researchers working there want to know whether astronauts can make fresh produce part of their diets if humans finally make it to Mars.

China's first plant to grow on the moon is already dead

China's first plant to grow on the moon is already dead The first plant to be grown on the moon by humans is likely dead already, Chinese scientists said Thursday. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); Just days after China revealed a cotton seed had sprouted on a lunar lander and become what was possibly the first plant life to grow on Earth's nearest neighbor, scientists ended the experiment when they shut down power remotely.

It may sound strange, but the coldest place in the Universe is not anywhere in the vast, cold outer space - it exists here on Earth . According to the Guinness Book of World Records, besides laboratory-created temperatures, “ the coldest place in the universe is in the Boomerang Nebula, a

Plants that grow up without mechanical stresses — due to wind, rain or other disturbances — “are much more susceptible to pests, are not as That overlap raises the stakes for understanding the impact of gravity on plants beyond the notion of building stronger crops that can stand up in the field.

Aside from the International Space Station (ISS), Neumayer may be one of the best places to investigate this issue. Located on the east coast of the Weddell Sea, on Antarctica’s Ekström Ice Shelf, the facility is reachable only by plane or icebreaker and only during the Antarctic summer, weather permitting. (Find out what Antarctica's calving glaciers look like.)

“It’s the closest place to space on Earth,” says photographer Esther Horvath, who spent nine days at the station in January. Neumayer is unlike other polar research stations because it is the only one that functions year-round on an ice shelf. Just nine crew members live there at a time, and they do much of their work in one big building, which is also equipped with a small basketball court, a big screen television, and other amenities for downtime.

China’s Moon Plants Have Died

China’s Moon Plants Have Died On Tuesday, China announced it had grown the first ever plants on the moon, days after landing on the moon’s “far side” Von Karman crater. The cotton seed sprouts seemed to have been able to withstand the harsh lunar conditions: freezing temperatures, lower gravity levels, and radiation. But by Thursday, the fledgling cotton seed sprouts had died, according to Liu Hanlong, the experiment lead, in a government press conference statement. The cause of death: Temperatures inside the 1-liter canister the plants were in had dived to -52 degrees Celsius. On January 3, China made the first ever soft-landing on the moon’s far side in the 115 foot-wide Von Kármán Crater.

When we go to Mars, weight will be precious. The less we carry with us, the better. Ultimately, NASA is trying to figure out how to grow plants with as little soil as possible, through methods Mastering plant growth in space and on other worlds will be important to future crews traveling on long-duration

Here are the hottest and coldest places of Earth . There are some places exist which probably you won't want to be there, at least uncovered. On average, Vostok also is the coldest place on Earth . The average temperature of the cold season (from April to October) is about −65 °C (−85 °F), while

“Basically, you could live an entire year in the station without leaving the building,” Horvath says. A rotation lasts 14 months, and during that time there is only one food delivery. Civilian visitors are not allowed. Given the remoteness of the location, it’s imperative that one of the team members be both a medical doctor and a surgeon. (See inside one of the world's northernmost science labs.)

Similar to life on the ISS, being at Neumayer means living and working in close quarters with a set group of people in an unforgiving landscape. Any trips outside require careful planning. And, Horvath says, “if anything [bad] happens, nobody can get there.”

That makes the greenhouse a bit of a beacon. It sits 1,200 feet from the main building where the scientists live and work. Assuming conditions aren’t too harsh, anyone can walk there and get a welcome dose of green amid all the gray and white.

“The other interesting thing is that you don’t smell anything in Antarctica, but then you come into the greenhouse and you smell tomatoes, peppers, cucumber, vegetables,” Horvath says. “It is something very calming and recharging.”

Antarctica is surely the coldest place on Earth but is it all one place ? Or many different points? But here are ten places you certainly would’t want to be striding around in swimwear. But that would be little comfort if you happened to visit in December and you knew it wasn’t going to warm up till Easter.

Psychological advantages aside, the greenhouse is already showing researchers how plants might thrive in deep space.

One intriguing challenge they’ve overcome is how to tend the garden remotely. Everything is grown aeroponically, which means the plants are suspended and the roots are exposed to air below. Nutrients are delivered via a sprayed solution rather than soil. This spraying—along with temperature control, lighting, and carbon dioxide adjustments—is operated from a mission control center at the German Aerospace Center in Bremen, Germany.

So far, the system works beautifully. And based on the reaction from the crew at Neumayer Station, a greenhouse like this one could dramatically improve life in outer space.

“Scientists and astronauts say one of the things they miss the most is the fresh vegetables and fresh salads,” Horvath says.

Because of its position on an ice shelf, Neumayer Station moves every day about 40 centimeters, inching closer to the ocean. And due to the harsh environment, the base will eventually be shut down. In the meantime, researchers there will continue to measure sea ice, ozone changes, and atmospheric conditions—and of course, grow and eat salad in the name of space exploration.

Colossal asteroid will approach Earth on Friday, but we’ll be fine.
NASA is always keeping an eye on space rocks that get anywhere near Earth, and 2019 has been a relatively calm year in terms of close passes. A recently discovered asteroid is going to make a not-super-close pass of Earth later this week, and while it doesn’t pose much of a threat to our planet it’s worth mentioning simply because of its size. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); The rock, known as 2019 DN, is slated to arrive at its closest point to Earth this coming Friday, March 8th.
