Japanese probe travels back to Earth with samples of distant asteroid

Tokyo – Japanese probe Hayabusa2 began its journey back to Earth after collecting samples of a distant asteroid, marking an unprecedented achievement in space exploration, the country’s aerospace agency announced Wednesday.

The probe began maneuvers to leave asteroid Ryugu’s orbit and return to Earth, a distance of 700 million kilometers that would take one year to cover, Japan Aerospace Exploration Agency (JAXA) tweeted.

If the probe returns without any setbacks, Hayabusa2 will become the first space mission to bring surface and underground samples from extremely distant celestial bodies, contributing to research into the mysteries of the universe, JAXA said.

On Wednesday at 10:05 local time (1:05 GMT), the probe activated its lithium-ion powered engine to lift itself from its orbital location – some 20 kilometers above the asteroid – and begin its return journey.

JAXA provided details of the operation named “Sayonara Ryugu” (Goodbye Ryugu) on its Twitter account and posted pictures taken by Hayabusa2.

According to JAXA’s plan, the probe will pass over Australia towards the end of 2020 and drop a capsule containing sand and rock samples collected from Ryugu.

Hayabusa2 reached the asteroid in 2018 and made two touchdowns this year, in what have been pioneering missions of high technical complexity.

Maneuvers were aimed at retrieving underground samples from an artificial crater on the surface of the asteroid created by a projectile made of the metal tantalum fired by the spacecraft.

Ryugu is located 340 million kilometers from the Earth and its surface is believed to contain traces of coal and water formed during the birth of the solar system some 4.6 billion years ago.

The samples collected by Hayabusa2 could provide clues to the formation of planets and the origin of life. EFE-EPA

Tokyo 2020 expects to secure all venues for Games — local media

UNTV News   •   July 9, 2020

Tokyo Olympics organizers expect to be able to use all the venues as originally planned at next year’s rearranged Games, several Japanese media outlets reported on Thursday (July 9).

Securing venues was a top priority for organisers after the Games were pushed back to 2021 due to the COVID-19 pandemic, and Kyodo and NHK, citing unnamed sources, said they were now confident they would be tied down for Olympics use again.

However, at his regular weekly news conference, Tokyo 2020 spokesman Masa Takaya said the reports were “optimistic” and that nothing had been announced.

Last month, Tokyo 2020 CEO Toshiro Muto said 80% of all venues needed had been secured, with the Athlete’s Village and Tokyo Big Sight, the planned media centre, among those yet to be fully secured.

Thursday’s reports also said the competition schedule would remain largely unchanged and that all tickets holders would be eligible for refunds, and that organisers would seek approval of these decisions from the IOC’s General Assembly on July 17.

Asked to confirm those details, Takaya said nothing had been decided and Tokyo 2020 did not expect to seek approval from the IOC next week. (Reuters)

Residents in southwestern Japan clean up after floods

UNTV News   •   July 9, 2020

People in southwestern Japan were busy cleaning up on Wednesday (July 8) following the aftermath of torrential rain that has pounded the area since the weekend killing dozens of people in floods and landslides.

In Hitoyoshi, a severe flood of the Kumagawa River destroyed houses along the riverbanks. Ruined home appliances and furniture lined local streets, while residents shovelled mud and bagged garbage. An excavator worked to clear debris.

As of Wednesday, 59 people have been confirmed dead, including 18 in Hitoyoshi. Seventeen people remain missing.

Meanwhile, the heavy rain moved into central Japan’s Nagano and Gifu prefectures. The country’s meteorological agency issued a heavy rain emergency in the two prefectures early Wednesday but downgraded the alert to a warning later in the day.

Water levels of rivers in the region were seen rising and officials are telling residents to stay vigilant. (Reuters)

Japan warns of more heavy rain in flood-hit areas, as death toll rises

UNTV News   •   July 7, 2020

Japan warned of more heavy rain on the southwestern island of Kyushu on Tuesday (July 7) as the death toll in flood-hit areas reached at least 50, with more than a dozen people reported missing.

“The ground formation has weakened from the rain. We fear there may be landslides even if it rains slightly. I ask residents to please be on alert for information released by local offices and watch out for rivers flooding,” Chief Cabinet Secretary Yoshihide Suga said at a regular news briefing, urging people to take the necessary precautions to ensure their safety.

Japan on Monday (July 6) issued a heavy rain emergency warning in three prefectures on Kyushu, including Nagasaki, Saga and Fukuoka but officials have downgraded the emergency warning to a warning on Tuesday. Police, Self Defense Force and Coast Guard units are conducting search and rescue effort, Suga said. (Reuters)
