Final preparations were underway on Friday for the launch of a joint mission by European and Japanese space agencies to send twin probes to Mercury, the closest planet to the sun.
An Ariane 5 rocket is scheduled to lift the unmanned spacecraft into orbit from French Guiana shortly before midnight, the start of a seven-year journey to the solar system’s innermost planet.

The European Space Agency says the €1.3 billion (US$1.5 billion) mission is one of the most challenging in its history. Mercury’s extreme temperatures, the intense gravity pull of the sun and blistering solar radiation make for hellish conditions.

Newly developed electrical ion thrusters will help nudge the spacecraft, which was named after Italian scientist Giuseppe “Bepi” Colombo, into the right orbit.

When it arrives, BepiColombo will release two probes – Bepi and Mio – that will independently investigate the surface and magnetic field of Mercury. The probes are designed to cope with temperatures varying from 430 degrees Celsius (806F) on the side facing the sun, and -180 degrees Celsius (-292F) in Mercury’s shadow.

Scientists hope to build on the insights gained by Nasa’s Messenger probe, which ended its mission in 2015 after a four-year orbit of Mercury. The only other spacecraft to visit Mercury was Nasa’s Mariner 10 that flew past the planet in the mid-1970s.

Mercury, which is only slightly larger than Earth’s moon, has a massive iron core about which little is known. Researchers are also hoping to learn more about the formation of the solar system from the data gathered by the BepiColombo mission.

WASHINGTON (Reuters) – President Donald Trump said on Wednesday he believes China’s handling of the coronavirus is proof that Beijing “will do anything they can” to make him lose his re-election bid in November.
In an interview with Reuters in the Oval Office, Trump talked tough on China and said he was looking at different options in terms of consequences for Beijing over the virus. “I can do a lot,” he said.
Trump has been heaping blame on China for a global pandemic that has killed at least 60,000 people in the United States according to a Reuters tally, and thrown the U.S. economy into a deep recession, putting in jeopardy his hopes for another four-year term.
The Republican president, often accused of not acting early enough to prepare the United States for the spread of the virus, said he believed China should have been more active in letting the world know about the coronavirus much sooner.
Asked whether he was considering the use of tariffs or even debt write-offs for China, Trump would not offer specifics. “There are many things I can do,” he said. “We’re looking for what happened.”
“China will do anything they can to have me lose this race,” said Trump. He said he believes Beijing wants his Democratic opponent, Joe Biden, to win the race to ease the pressure Trump has placed on China over trade and other issues.
“They’re constantly using public relations to try to make it like they’re innocent parties,” he said of Chinese officials.
He said the trade deal that he concluded with Chinese President Xi Jinping aimed at reducing chronic U.S. trade deficits with China had been “upset very badly” by the economic fallout from the virus.
A senior Trump administration official, speaking on condition of anonymity, said on Wednesday that an informal “truce” in the war of words that Trump and Xi essentially agreed to in a phone call in late March now appeared to be over.
The two leaders had promised that their governments would do everything possible to cooperate to contain the coronavirus. In recent days, Washington and Beijing have traded increasingly bitter recriminations over the origin of the virus and the response to it.
However, Trump and his top aides, while stepping up their anti-China rhetoric, have stopped short of directly criticizing Xi, who the U.S. president has repeatedly called his “friend.”
Trump also said South Korea has agreed to pay the United States more money for a defense cooperation agreement but would not be drawn out on how much.
“We can make a deal. They want to make a deal,” Trump said. “They’ve agreed to pay a lot of money. They’re paying a lot more money than they did when I got here” in January 2017.
The United States stations roughly 28,500 troops in South Korea, a legacy of the 1950-53 Korean War that ended in an armistice, rather than a peace treaty.
Trump is leading a triage effort to try to keep the U.S. economy afloat through stimulus payments to individuals and companies while nudging state governors to carefully reopen their states as new infections decline.
Trump sounded wistful about the strong economy that he had enjoyed compared with now, when millions of people have lost their jobs and GDP is faltering.
“We were rocking before this happened. We had the greatest economy in history,” he said.
He said he is happy with the way many governors are operating under the strain of the virus but said some need to improve. He would not name names.
Trump’s handling of the virus has come under scrutiny. Forty-three percent of Americans approved of Trump’s handling of the coronavirus, according to the Reuters/Ipsos poll from April 27-28.
But there was some good coronavirus news, as Gilead Sciences Inc said its experimental antiviral drug remdesivir was showing progress in treating virus victims.
Trump has also seeking an accelerated timetable on development of a vaccine.
“I think things are moving along very nicely,” he said.
At the end of the half-hour interview, Trump offered lighthearted remarks about a newly released Navy video purportedly showing an unidentified flying object.
“I just wonder if it’s real,” he said. “That’s a hell of a video.”

- Zhuhai police, at the end of the world’s longest sea bridge, use body armour and tear gas in preparation for Macau’s 20th anniversary celebration
- Hong Kong is just an hour’s drive away from Macau using the bridge

Armed police in the southern Chinese city of Zhuhai held a massive anti-terror drill at its end of the Hong Kong-Zhuhai-Macau Bridge on Friday morning as part of its preparations for the 20th anniversary of the handover of Macau, when President Xi Jinping is expected to visit the city.
More than 1,000 police officers and 80 vehicles were involved in the exercise, amid
, according to local news portal Southcn.com.
Photos circulated online showed officers in body armour, helmets and shields firing tear gas as they confronted a group of people carrying sticks and wearing black shirts and yellow helmets – attire associated with the protesters in Hong Kong, 60km (37 miles) away from Macau.
The drill was held three weeks before the 20th anniversary of Macau’s return to Chinese administration under the “one country, two systems” policy on December 20.

Security is expected to be tightened when Xi visits the city, in response to the violent clashes in Hong Kong over the past six months, which Beijing has repeatedly blamed on radical protesters.
The former Portuguese colony is connected to Hong Kong and its neighbouring city of Zhuhai, Guangdong province, by the world’s longest sea crossing bridge. It takes about an hour to drive from Hong Kong to Macau via the bridge.
Guo Yonghang, Zhuhai party chief, urged the local police to stay loyal to the party. “[Police] should be loyal and fulfil duty and mission to create a peaceful and stable political and social environment for the construction of the Guangdong-Hong Kong-Macau Greater Bay Area and the celebration of the 20th anniversary of Macau’s reunification to the motherland,” he said.
Macau was returned to China two years after Hong Kong and celebrations of its success under one country, two systems could be overshadowed by its neighbour’s anti-government protests which stemmed from opposition to proposed extradition legislation and have escalated into violence on the streets and in university campuses.
In August, two months after more than 2 million people in Hong Kong took to the streets to protest the now-suspended extradition bill, police in Shenzhen held at least three drills featuring anti-riot exercises involving tear gas, armoured vehicles and water cannon.
