China launched a spacecraft bound for its unfinished space station just past midnight Saturday local time. On board were three astronauts — including the first woman to visit the station.

The Shenzhou-13 spacecraft took off from the Gobi Desert in northern China. Zhai Zhigang, who was chosen as mission commander for the six-month trip, graduated from China's first group of astronaut trainees in the 1990s. Selected from more than 1,500 potential astronaut candidates in 1998, Zhai, once a fighter pilot in the Chinese People's Liberation Army, eventually conducted China's first spacewalk. “After 13 years, I am going to set out for outer space again,” Zhai said to reporters. “I feel excited. I feel inspired. I also feel some pressure.” Wang Yaping, 41, is the first female astronaut to visit the Chinese station and the second Chinese woman to enter space.

China has spent a decade working to develop technologies for a space station. Construction of the nation’s first permanent space station, Tiangong, started in April. It is planned to include three elements. One, called Tianhe or “Heavenly Harmony,” is just bigger than a city bus and serves as the main living district. Eleven missions will be needed to fully supply and complete the station.

The six-month trip marks another step in the nation's rapidly advancing space program.

Three Chinese astronauts returned in September from a successful 90-day visit to the station, spending their time checking Tianhe's life-support system and going on spacewalks.

“We will definitely encounter physical and psychological problems, as well as problems related to the equipment and facility,” Zhai told reporters Thursday. “Whether we can complete this flight mission well depends on our team, our firm will and the fighting spirit of our three crew members.” He added that the crew's two years of training together gives them the "]”power and wisdom” to resolve all difficulties.

Ahead of the launch, Beijing renewed a commitment to cooperate with the international peaceful use of spare Foreign Ministry spokesman Zhao Lijian described sending people to space as a “common cause of mankind.” Zhao said China would “continue to extend the depth and breath of international cooperation and exchanges” in spaceflight and “make positive contributions to the exploration of the mysteries of the universe.”

Many are familiar with the potentially deadly danger caused by lightning, which is blamed for an average of 43 deaths in the United States each year, based on data from 1989 to 2018. However, the researchers recently uncovered a surprising and beneficial impact of lighting.

Published at the end of April in Science, the new study found that lightning may play a bigger role in global climate change than what was previously known by the   scientific community, “Lightning increases the atmosphere's ability to clean itself,” the researchers wrote in the study.

The study, which included efforts from nine atmospheric experts across a dozen universities and meteorological agencies, was based on an airborne research flight conducted by a NASADC-8 storm-chasing plane in 2012. The plane used to examine the top part of the top part of thunderstorm clouds, which are known as anvils (砧状云).

According to Dr.William Brune, a professor of meteorology and atmospheric sciences at Pennsylvania State University and co-author of the study, researchers initially thought there was a problem with the equipment on the plane, which was being used to measure the hydroxyl radicals（羟基自由基）in the atmosphere. But soon they realized the sharp increase they observed came along with lightning flashes.

Hydroxyl radicals, described as a “chemical cleaner” by Science Direct, are important chemical compounds (化合物) found in the atmosphere due to the reactive nature with other organic molecules (有机分子).

Researchers previously understood that lightning could help to clean the atmosphere, but there was no evidence that it could produce compounds like these radicals. As a result, the study estimates that somewhere between 2% and 16% of the cleaning that happens naturally in the Earth's atmosphere, is done by lightning.

Why is this significant? The existence of the hydroxyl radicals helps to reduce chemicals like carbon dioxide and methane in the atmosphere. These chemicals, known for greenhouse gases, have been proven to contribute to rising temperatures associated with climate change.
