South Korea area rocket launch places satellites in orbit

Published

Seoul: South Korea mentioned Tuesday it had efficiently launched its homegrown area rocket and positioned a payload into orbit in a “big leap” for the nation’s quest to change into a complicated space-faring nation.

Korea Satellite tv for pc Launch Car II, nicknamed Nuri and emblazoned with the South Korean flag, lifted off at 4:00pm (0700 GMT) from the launch web site in Goheung on the southern coast, trailing a column of flame.

All three phases of the rocket labored, taking it to its goal altitude of 700 kilometres (430 miles), and it efficiently separated a efficiency verification satellite tv for pc and put it into orbit, Seoul mentioned.

South Korea’s area program “has taken an enormous leap ahead,” mentioned Lee Jong-ho, minister of science and know-how, including he declared the mission a hit.

“South Korea has now change into the seventh nation on the earth to launch an area automobile with homegrown know-how,” he mentioned, including the federal government would proceed its quest to change into “a complicated space-faring nation”.

South Korea will launch a Moon orbiter in August, Lee added. The Tuesday take a look at, South Korea’s second take a look at launch of its homegrown area rocket, comes eight months after the primary take a look at didn’t put a dummy satellite tv for pc into orbit.

Within the first take a look at final October, all three phases of the rocket labored with the automobile reaching an altitude of 700 kilometres, and the 1.5-tonne payload separating efficiently.

But it surely didn’t put a dummy satellite tv for pc into orbit after the third-stage engine stopped burning sooner than scheduled.

In Tuesday’s take a look at, along with a dummy satellite tv for pc, Nuri carried a rocket efficiency verification satellite tv for pc and 4 dice satellites developed by 4 native universities for analysis functions.

The three-stage Nuri rocket has been a decade in improvement at a value of two trillion gained ($1.5 billion). It weighs 200 tonnes and is 47.2 metres (155 toes) lengthy, fitted with a complete of six liquid-fuelled engines.

In Asia, China, Japan and India all have superior area programmes, and the South’s nuclear-armed neighbour North Korea was the newest entrant to the membership of nations with their very own satellite tv for pc launch functionality.

Lunar ambitions –

Ballistic missiles and area rockets use comparable know-how and Pyongyang put a 300-kilogram (660-pound) satellite tv for pc into orbit in 2012 in what Washington condemned as a disguised missile take a look at.

South Korea turns into the seventh nation — not together with North Korea — to have efficiently launched a one-tonne payload on their very own rockets.

The South Korean area programme has a blended document — its first two launches in 2009 and 2010, which partially used Russian know-how, each resulted in failure.

The second exploded two minutes into the flight, with Seoul and Moscow blaming one another.Ultimately a 2013 launch succeeded, however nonetheless relied on a Russian-developed engine for its first stage. “The truth that we now have our personal area rocket means we will take a look at and confirm applied sciences wanted for area exploration tasks down the street,” Bang Hyo-choong, professor of aerospace engineering at KAIST, advised the Yonhap Information Company.

The satellite tv for pc launch enterprise is more and more the protect of personal firms, notably Elon Musk’s SpaceX, whose shoppers embody the US area company NASA and the South Korean navy.

The Tuesday take a look at appears to be like set to carry South Korea nearer to attaining its area ambitions, together with a plan to land a probe on the Moon by 2030.

New US examine helps de-mystify Covid mind fog

Published

WASHINGTON: A small new examine printed Tuesday by scientists on the US Nationwide Institutes of Well being means that the immune response triggered by coronavirus infections damages the mind’s blood vessels and could possibly be answerable for lengthy Covid signs.

The paper, printed within the journal Mind, was based mostly on mind autopsies from 9 individuals who died immediately after contracting the virus.

Moderately than detecting proof of Covid within the mind, the workforce discovered it was the folks’s personal antibodies that attacked the cells lining the mind’s blood vessels, inflicting irritation and injury.

This discovery might clarify why some folks have lingering results from an infection together with headache, fatigue, lack of style and scent, and lack of ability to sleep in addition to “mind fog” — and may additionally assist devise new remedies for lengthy Covid.

NIH scientist Avindra Nath, the paper’s senior creator, mentioned in an announcement: “Sufferers usually develop neurological issues with COVID-19, however the underlying pathophysiological course of is just not nicely understood.”

“We had beforehand proven blood vessel injury and irritation in sufferers’ brains at post-mortem, however we didn’t perceive the reason for the injury. I feel on this paper we’ve gained essential perception into the cascade of occasions.”

The 9 people, aged 24 to 73, have been chosen from the workforce’s prior examine as a result of they confirmed proof of blood vessel injury of their brains based mostly on scans.

Their brains have been in comparison with these from 10 controls, with the workforce analyzing neuroinflammation and immune responses utilizing a method known as immunohistochemistry.

The scientists found that antibodies produced towards Covid-19 mistakenly focused cells that kind the “blood-brain barrier” — a construction designed to maintain dangerous invaders out of the mind whereas permitting mandatory substances to move.

Harm to those cells may cause leakage of proteins, bleeding and clots, which elevates the chance of stroke.

The leaks additionally set off immune cells known as macrophages to hurry to the location to restore injury, inflicting irritation.

The workforce discovered that ordinary mobile processes within the areas focused by the assault have been severely disrupted, which had implications for issues resembling their capacity to de-toxify and to control metabolism.

The findings supply clues concerning the biology at play in sufferers with long-term neurological signs, and might inform new remedies — for instance, a drug that targets the build-up of antibodies on the blood-brain barrier.

“It’s fairly doable that this identical immune response persists in Lengthy COVID sufferers leading to neuronal harm,” mentioned Nath.

This may imply {that a} drug that dials down that immune response might assist these sufferers, he added. “So these findings have crucial therapeutic implications.”
