Two flights into Abbotsford have had recent COVID-19 exposures – Agassiz-Harrison Observer

Published

 on


Two flights to Abbotsford have each had a recent COVID-19 exposure, according to the B.C. Centre for Disease Control (CDC).

The agency indicates on its website that the flights involved were WestJet flight 637 from Calgary to Abbotsford on Wednesday, Oct. 14 (rows nine to 15) and Swoop flight 107 from Hamilton to Abbotsford on Monday, Oct. 19 (rows 20 to 26).

The CDC advises that anyone who was on these flights should self-monitor for symptoms for 14 days.

Passengers on domestic flights are not required to self-isolate, but those who have travelled outside of Canada are required to self-isolate for 14 days upon their arrival.

Passengers seated on a plane with a case of COVID-19 that was later identified are no longer directly notified of their potential exposure. Instead, anyone who has travelled is asked to monitor the CDC website.

Passengers seated in the affected rows are considered to be at higher risk of exposure due to their proximity to the case.

Watch unreal drone footage of Arecibo Observatory's catastrophic collapse – CNET

Published

 on


The National Science Foundation released stunning video footage Thursday capturing the exact dramatic moment the Arecibo Observatory’s 900-ton platform fell into the 1,000-foot wide dish below. A drone happened to be performing an up-close investigation of the cables that still held the platform above the dish as the cables snapped on Tuesday.

The video of the massive radio telescope shows both the drone footage and the view from a camera in the visitor center that shows the platform falling into the dish just above the jungle floor in Arecibo, Puerto Rico. Two massive chunks of the cement towers that the cables were attached to can also be seen falling.

Two of the cables had previously broken, one in August and another in November, destabilizing the telescope.

A drone was inspecting the site atop one of the towers, where one of the previous cable breaks had occurred, when the rest suddenly snapped. 

The NSF had recently decided to decommission the telescope after a second cable broke in November.

“It was a dangerous situation,” John Abruzzo, who is with an engineering consulting firm called Thornton Tomasetti that was contracted by the NSF, told reporters Thursday. “Those cables could have failed at any time.” 

On Tuesday, they did.

The NSF reports that no one was injured in the collapse and that the visitor center sustained only minor damage.

The telescope, which functioned for nearly 60 years, was the backdrop to a dramatic fight scene in the 1995 James Bond movie GoldenEye with Pierce Brosnan. It also appeared in the 1997 Jodie Foster movie Contact. But Arecibo’s true legacy lies in the many scientific discoveries it made possible. It explored pulsars, expanded our knowledge of Mercury, spotted exoplanets and found fast radio bursts.

Unfurling China's flag on moon_china.org.cn – China.org.cn

The China National Space Administration Friday released images showing China’s national flag unfurled from the Chang’e-5 probe on the moon.

The images were taken by a panoramic camera installed on the lander-ascender combination of the probe, before the ascender blasted off from the moon with lunar samples late Thursday.

In one of the images, a robotic arm to collect lunar samples can be seen next to the flag.

On Dec. 15, 2013, color images showed the Chinese flag on the country’s first moon rover Yutu, the first time the five-star red flag had been pictured on an extraterrestrial body.

Unlike the flags in China’s previous lunar missions, the flag on Chang’e-5 was made of real fabric, rather than a spray coating. Chinese engineers and technicians revealed the advanced engineering behind the special flag.

A flag made from traditional fabrics would most likely lose color and disintegrate in the harsh lunar environment of abrasive dust, unfiltered cosmic rays and solar flares.

The flag must also be as light and compact as possible, as the spacecraft has very little room for anything more than scientific equipment.

Last but not least, how to make the flag stay perfect en route to the moon and look good on camera?

The flag team from China Aerospace Science and Industry Corporation Ltd. chose a scroll design, so the flag unfurls smooth and flat and not wrinkled and drooping.

It took them more than a year to find a new composite material that could stand the harsh environment and be dyed in China’s vivid national colors. After being rolled up, the fabric will not stick together in temperatures ranging from 150 degrees Celsius to 150 degrees below zero. The flag made from the fabric only weighs 12 grams.

Li Yunfeng, director of the flag system, said the flag system used a mechanical structure that has been applied to the unfolding of solar panels on satellites and spacecrafts. The structure also makes the system weighing no more than 1 kg.

At the top is a hollow ball structure to fix the flag. Engineer Huang Min and lathe operator Liao Guangheng were inspired by Gashapon capsule toys in making it so light.

A flag represents the dignity and honor of a country, said Huang and Liao: “We have to make sure it’s spotless and infallible.”

A detonator unfurls the flag. To make sure it unfurled in one second sharp, the team simulated the lunar environment with a massive temperature difference between day and night, and carried out dozens of tests.

Liu Haigang, a veteran milling machine operator, said the parts he was responsible for were the most difficult challenge of his career.

He said he felt so proud when he finally put the finished pieces in the box as it was like looking at a work of art.

“When it lands on the moon, I’ll tell my grandson ‘Grandpa made this’.”

China’s Chang’e-5 probe was launched on Nov. 24, and its lander-ascender combination touched down on the north of the Mons Rumker in Oceanus Procellarum, also known as the Ocean of Storms, on the near side of the moon on Dec. 1.

After the samples were collected and sealed, the ascender of Chang’e-5 took off from the lunar surface late Thursday, and is expected to carry out unmanned rendezvous and docking with the orbiter-returner in lunar orbit, an unprecedented feat.

Chang’e-5 is one of the most complicated and challenging missions in Chinese aerospace history, as well as the world’s first moon-sample mission in more than 40 years.

Chinese Chang'e-5 Is Returning From Moon With Rocks, Left A Flag To Celebrate – KCCU

Published

 on


China’s lunar probe Chang’e-5 is on its way back to Earth after a brief visit to the moon Thursday. The craft collected soil and rock samples over the course of about 19 hours and then left the lunar surface.

The samples are expected to land on Earth around the middle of the month.

Before it left, the spacecraft planted a flag there — making China only the second country to leave its national banner on the moon. China hadn’t deployed one in two previous landings.

Getting a flag to the moon isn’t easy and solar radiation has likely bleached out the ones planted by U.S. astronauts, according to NASA.

For China, its most recent accomplishment has a nostalgic feel, aerospace expert and TV commentator Song Zhongping told China’s Global Times. It has been more than half a century since the NASA Apollo 11 crew walked on the moon.

“Yesterday’s memory is still fresh and clear, when the U.S. astronauts stepped outside their cabins and planted the first flag in human history, an American national flag, on the moon in 1969,” Zhongping said. “But China is about to showcase our own national flag as well, which I believe is a recognition of achievements and breakthroughs that we have made, which will be the most valuable thing.”

The Soviet Union was the first country to leave its mark on the moon, intentionally smashing the Luna 2 probe there in 1959.
