  • Scientists track the Chinese Space Station
  • It will fall on Earth soon
  • Scientists are trying to locate the exact location where it will fall

Scientists are monitoring a defunct Chinese space station that is expected to fall to Earth around the end of the month, the largest manmade object to re-enter Earth’s atmosphere in a decade.

The head of the European Space Agency’s debris office, Holger Krag, says China’s Tiangong-1 space station will likely fall to Earth between March 30 and April 3.

Krag said it still not yet known where the space station will hit Earth, but said it would be extremely unlikely for anyone to be injured when it does.

Injury unlikely

“Our experience is that for such large objects typically between 20 and 40 percent of the original mass, of 8.5 tons, will survive re-entry and then could be found on the ground, theoretically,” he said.

“However, to be injured by one of these fragments is extremely unlikely. My estimate is that the probability to be injured by one of these fragments is similar to the probability of being hit by lightning twice in the same year,” Krag added.

He said the space station is expected to fall between the areas of 43 degrees south and 43 degrees north, and everything outside that zone is considered safe.

“Northern Europe including France, Germany, Austria and Switzerland are definitely on the safe side. Southern Europe, the southern part of North America, South Asia, Africa, Australia and also South America are still within the zone today,” he said.

Where will it hit?

Scientists say it is hard to predict where Tiangong-1 will hit Earth in part because of its low orbit and high velocity. They say the space station is travelling 17,400 mph and orbits Earth about every 90 minutes.

Tiangong-1 was launched into orbit in 2011 as China’s first space lab. It carried out orbit experiments in preparation for China’s plan to put a permanent space station into orbit by 2023. VOA

Trade War Between Washington and Beijing Effecting Farmers

Roger Lande says sometimes China does things “we don’t like,” but all relationships, with family, friends and business associates, have ups and downs.

China, USA, Trade War

The trade war between Washington and Beijing is hurting farmers who grow huge amounts of soybeans in Iowa for export to the massive Chinese market.

Farmers in Iowa hope that the strong commercial and close personal relationships that China and the U.S. farm state have nurtured for many years will help the two sides overcome complications like the record U.S. trade deficit with China.

Chinese President Xi Jinping has visited Iowa farmers repeatedly over the past couple of decades and former Iowa governor Terry Branstad is now the U.S. ambassador to Beijing.

The close ties have been strained by Washington’s allegations that China unfairly manipulates markets, steals American intellectual property, and creates bureaucratic obstacles to trade. China also accuses the United States of unfair practices.

Tariff war

The United States imposed tariffs on Chinese exports, and Beijing retaliated with tariffs on American agricultural products.

That meant that Iowa soybeans were more expensive and less competitive on global markets.

Demand for U.S. soybeans — and prices paid to U.S. farmers — plunged $85 a metric ton.

An Iowa farmer who manages several farms, including 153 hectares of soybeans, says his profits fell 100 percent for 2018. David Miller is not happy to lose money but says without the tariffs, China would not pay any attention to the talks.

Needing each other

China really needs what Iowa produces, according to Grant Kimberley, the marketing manager for the Iowa Soybean Association, who has been to China more than 20 times.

“China needs soybeans … because their middle class has grown, and that means they are eating more protein in their diet, more meat, and if you have more meat production, you have to have more soybeans to feed those animals,” he said.

Kimberley’s family runs a 600 hectare farm, 48 kilometers from Des Moines, which was one of the places visited by Xi, who saw that it uses more advanced equipment and technology than is available to Chinese farmers.

The former director of Iowa’s department of natural resources, Roger Lande, and his wife, Sarah, have twice hosted Xi, at their home in the small town of Muscatine.

Kimberley is optimistic things will work out.

“Because that’s a long-standing relationship that’s been in place for 35 years,” he said. And “I think the overall underlying support and the people that are involved between the states and the province is still strong. And, and everybody recognizes that, over the long term, eventually this will get resolved,” he added. (VOA)
