The cabinet is expected to meet on Wednesday with close contact rules high on the agenda amid Omicron’s push.

Current advice from the European Center for Disease Prevention and Control allows for shorter periods of isolation when there is significant pressure on society and healthcare in particular.

The government is due to receive public health advice on the matter before making a decision on Wednesday.

No other restrictions are expected to be relaxed at this early stage, nor does the Taoiseach expect any to be reinstated amid a daily case count of 20,000.

Mr Martin said he was confident the country could cross the Omicron wave without any other restrictions.

He said: “I’m at this point and it says we want to give him another week or two.

“We haven’t peaked yet and Covid has seen a lot of twists and turns, but I have no doubts that if we maintain the same focus, we can get through this wave.”

Mr Martin also said Dr Holohan told him the peak of the Omicron wave could be in two weeks.

He said: “Over 1,000 in hospital, luckily the conversion to intensive care is not at the same level as it would have been last year or in different waves.

“We need a little more time to wait to be sure.



Taoiseach, Michael Martin

“We’re still not at the top of this wave, it’s still on an upward trajectory but so far I think the country is handling that.

“We have to stick with it and I urge people in this context to get the booster shot.”

Pubs call for end of closing time at 8 p.m.

Hotel bosses say the current measures in place, including that all restaurants, bars and cafes must close at 8 p.m. and enforce strict social distancing, should be reviewed immediately.

Speaking to the Irish Daily Star, Mr Cummins said: ‘We are awaiting the lifting of the curfew. We need to see the scientific evidence around the 8 hour restrictions.

“Al fresco dining and alfresco hospitality must be reactivated immediately. A lot of companies invest huge sums of money in it to be able to dine al fresco.

“We need the resumption of normal trading hours. We need to see the evidence as to why the restrictions were introduced.

“The Taoiseach has ruled him out for this week, but that doesn’t mean he can’t stand up the following week.

“Restaurants are still struggling after Christmas time. “

North Korea’s strategic vision for 2022: focus on rural development https://templodoconhecimento.com/north-koreas-strategic-vision-for-2022-focus-on-rural-development/ Sat, 01 Jan 2022 23:47:35 +0000 https://templodoconhecimento.com/north-koreas-strategic-vision-for-2022-focus-on-rural-development/

The 4th plenum: main points to remember

The 4th plenum of the 8th Central Committee of the Korean Workers’ Party met in Pyongyang for five days, from December 27 to December 31, 2021. North Korean leader Kim Jong Un attended the meeting in his capacity as secretary general of the Party and gave at least two great speeches. As in 2020 and 2021, this public appearance at a major event around the start of the New Year has replaced the hitherto usual New Year’s speech.

(Source: Rodong Sinmun)

Regarding the formalities, it appears the North Korean leadership has learned lessons from what they might have viewed as past communication errors. Rather than providing the full texts of Kim Jong Un’s speeches, as was done at the 7th Party Congress in 2016, state media reported on them this year in the third person and only as rough summaries. . They omitted details on sensitive issues and thus made interpretation by outside observers more difficult. For example, readers of the state media were simply told that the leader “made extensive reference to the gaps and important lessons revealed in this year’s work and ways to address them.” We can assume that more details could be provided in the internal ideological education materials, but until they are disclosed, that’s all there is.

As far as we know, Kim Jong Un gave two speeches or reports at the 4th Plenum. Under the title “On the direction of the work of the Party and the State in 2022”, he summarized in a relatively standardized form the achievements of the past and outlined some priorities for the year to come. Its second report was more specific and focused entirely on rural development and agriculture: “Let us start a new great era in our style of socialist rural development.

The main lessons of the two speeches are easily summarized.

  1. There was no reference to foreign policy; neither to the relationship with the United States, nor to the relationship with South Korea. No new initiatives have been announced, but no new threats have been issued. No complaints were lodged regarding sanctions, military exercises or “hostile policies”.
  2. The army was only mentioned very briefly. No new weapons system has been announced, and there has been no threat of nuclear testing or ICBMs. That doesn’t mean none of them will take place in 2022. Given North Korea’s seemingly low position on the Biden administration’s priority list, such strategic weapons tests – which haven’t happened since 2017 – would be among the more obvious choices for Pyongyang. continue if management decides it needs more attention.
  3. There was no sign of further economic reforms or market-oriented liberalization. Rather, we find approaches and terminology that date back many years, if not decades. Retaining his position announced at the 8th Party Congress in January 2021, the North Korean leader seems determined to face the current situation by strengthening the role of the state, canceling previous reformist experiments and refocusing the economy on import substitution and the highest possible degree of autonomy and self-sufficiency. The term socialism / socialist (사회주의) appears 60 times in the related KCNA article, and Kim Jong Un is said to have praised “the power of collectivism” and the strict “discipline of the plan.”
  4. The most important and central topic of Kim Jong Un’s public appearances at the 4th Plenum was on “solving the problem of food, clothing and housing for the people”, especially development and agriculture. Although he promised an “improvement in the living conditions of the people” (인민 생활 향상) ten years ago at the start of his reign, the leader has not yet fulfilled this mission. His attention to this problem today could therefore be as much a reference to his own past as to current conditions and challenges. Earlier attempts in 2012 demonstrated a willingness to experiment with things such as Chinese-style land reform, smaller work teams, decentralization, and commercialization. In his speeches at the 4th Plenum, Kim Jong Un went in the opposite direction: farmers are supposed to be ideologically motivated, the state’s economic orientation in agriculture needs to be strengthened, and modernization modeled on the movement of farmers. three revolutions of the 1970s is supposed to make country life more attractive and productive. The silver bullet for increasing production will be science and technology, not a more effective incentive system.

The higher education sector is experiencing sustained growth https://templodoconhecimento.com/the-higher-education-sector-is-experiencing-sustained-growth/ Fri, 31 Dec 2021 07:56:00 +0000 https://templodoconhecimento.com/the-higher-education-sector-is-experiencing-sustained-growth/

In the field of higher education, Qatar has seen increasing growth in the number of higher education institutions, bringing their number in 2021 to 32 institutions, offering 365 academic programs in various educational pathways.

Qatar has seen steady growth in the number of scientific research institutions and centers, reaching 33 this year, with interests ranging from environment, energy, medicine, entrepreneurship to computer science, as well as social, humanitarian and educational studies, technological innovations and sustainable development. . Qatar’s efforts in the field of education have not been limited to the local sphere alone, but have extended to all regions of the world, especially marginalized communities, places of conflict and hard-to-reach areas. .

The state is currently working through its funding, humanitarian and development arms and partnerships with many organizations, governments and agencies in different countries of the world to step up efforts to educate more than 364,000 refugee children in 14 country, with the aim of bringing the total number of refugee children in school to 1.5 million children worldwide.

The vital and important achievements made according to systematic and studied plans and strategies in these sectors undoubtedly confirm that Qatar pursues with boundless confidence and ambition its efforts to achieve its global and sustainable development goals in all files and sectors. , especially in the health and education sectors, since an educated and healthy citizen is more able to put in effort and give and actively contribute to the growth and progress of his country, under the able leadership of the emir SA Sheikh Tamim bin Hamad Al Thani.

These achievements embody the rational approach adopted by the State in the implementation of its development policies, including health and education, with efficiency, quality and competence, for the benefit of its current and future generations, which confirms that Qatar is now one of the developed countries. . He anticipates a new year, during which the march of achievements will continue in all sites and in all fields.

In the context of these achievements, Qatar has made progress in managing the priorities set out in the Berlin Declaration on Education for Sustainable Development last May, including those related to public policies, the transformation of learning environments, development of the capacities of teachers, the empowerment of young people and the acceleration of procedures at the national level through the actions and measures it has taken in accordance with the second strategy of the education and training sector (2018-22) and the plan of the Ministry of Education and Higher Education, which stem from the Qatar National Vision 2030.

Life on Venus could be hiding in its strange clouds https://templodoconhecimento.com/life-on-venus-could-be-hiding-in-its-strange-clouds/ Wed, 29 Dec 2021 15:40:00 +0000 https://templodoconhecimento.com/life-on-venus-could-be-hiding-in-its-strange-clouds/

A team of scientists modeling the Venusian atmosphere have found data that could help explain the puzzling chemistry of the planet’s clouds. The findings reinforce the possibility that life exists in Venus’ atmosphere, a still controversial idea that will be investigated by several planned missions to the scorching planet.

Venus is the second planet from the Sun, which makes it much hotter than Earth. Besides the warmth of the planet, Venus is a barren, rocky wasteland dominated by volcanoes and clouds of toxic sulfuric acid. This cloud layer – about 19 km thick – covers the planet’s surface for Earth-based observers most of the time, and recently it has been in the spotlight as a possible hiding place for alien life.

Recent research has modeled these clouds more deeply, and scientists have found that the planet’s clouds are not entirely composed of sulfuric acid but contain a certain amount of mixed ammonium salt sludge. The team’s study was published in the Proceedings of the National Academy of Sciences.

“Our model predicts that clouds are not made entirely of concentrated sulfuric acid, but that cloud droplets are partially neutralized. Our model postulates that the compound that neutralizes acid in clouds is ammonia, ”Janusz Petkowski, an MIT astrobiologist and co-author of the recent study, said in an email. “The source of ammonia is unknown, but could be the result of the biological production of ammonia in cloud droplets. Due to the neutralization of acid, clouds are not more acidic than some extreme terrestrial environments that harbor life.

The recent work builds on high-profile research published last year in Nature, which claimed to detect phosphine gas in the Venusian atmosphere. (The scientists behind the new article were also among the authors of the article on phosphine.) Phosphine is produced by microorganisms that do not need oxygen to survive, so the presence of the gas was a surprising and exciting sign that something biological could be happening in those clouds. The conclusion was controversial; other researchers said the supposed signal from phosphine was actually just sulfur dioxide, while others suggested that active volcanoes, not life, could be responsible for it.

“To our knowledge, no life could survive in the droplets of Venus,” Sara Seager, an MIT planetologist and co-author of the new study, said in a statement from the institute. “But the point is, maybe some life is out there and changing its surroundings to be habitable.”

The new article did not focus on phosphine but rather on some unexplained chemical signatures in the clouds of Venus. Years of observations have indicated more water vapor and sulfur dioxide than expected. Ammonia, the researchers thought, could explain these anomalies.

“Ammonia shouldn’t be on Venus,” Seager added. “There is hydrogen attached to it, and there is very little hydrogen around. Any gas that does not belong to the context of its environment is automatically suspected of being manufactured by life.

The models indicated that if microorganisms were on Venus and produced ammonia, oxygen would be released as a byproduct. Additionally, ammonia (which is basic) would neutralize sulfuric acid droplets in clouds, making them somewhat habitable. While all of this work has been done with models, future space probe missions could help us get answers to what is really going on in the clouds.

These missions are NASA’s VERITAS and DAVINCI + missions, ESA’s EnVision Orbiter, and (possibly) the privately-offered and funded Venus Life Finder missions Seager and Petkowski are working on. The latter is the only one whose fundamental goal is to study the possibility of extraterrestrial life on Venus, but space agency missions will likely glean information on the matter as well. Of these three missions, DAVINCI + is the only mission that will actually enter the atmosphere of Venus and sample it as the spacecraft descends to the surface of the planet.

If life of any kind were discovered off Earth – whether fossilized on the surface of Mars, thriving in the clouds of Venus, or swimming in the ocean of a frozen moon – it would be one of the most important scientific discoveries of all time. But there is a long and uncertain road before such claims can be made.

Commentary: The Power Poll – A Sneak Peek into 2022 (and Beyond) – Tennessee Lookout https://templodoconhecimento.com/commentary-the-power-poll-a-sneak-peek-into-2022-and-beyond-tennessee-lookout/ Mon, 27 Dec 2021 19:26:59 +0000 https://templodoconhecimento.com/commentary-the-power-poll-a-sneak-peek-into-2022-and-beyond-tennessee-lookout/

Nashville’s economy will continue its thunderous roar through 2022 and build on the explosive growth of previous years, according to the December Nashville Power Poll. Members were also asked if it would be a good or a bad thing if Facebook opens a huge headquarters here, as they say. A majority of members thought this would be a positive development; only 16% viewed it negatively.

On the policy side, Power Poll members believe the Jim Cooper Congressional District, which includes all of Davidson County, will soon be divided when the General Assembly conducts its ten-year redistribution of the district’s boundaries. However, most believe he will somehow survive and be re-elected. As for his brother, John, who is our mayor and is running for re-election in 2023, most believe it is far too early to guess whether he will be re-elected or replaced. This despite the fact that whenever two or more Nashville political junkies get together, John Cooper’s political future is all they can talk about.

Finally, in our irrelevant but insightful question of the month, we asked if people are enjoying their office parties this year. More than half did not. This is life in the age of COVID. Those who had one had a fabulous time. Only 2% found theirs boring.

Here are the answers and specific questions to the December Nashville Power poll.

The Power Poll is not a scientific poll. Power Poll only asks questions of those in positions of influence, that is, those who hold the levers of power in one way or another. To that extent, it is a fascinating glimpse into the position of the powers that be in a particular city on issues of local importance. 1,042 Nashville Power Poll members received the survey, 405 responded, for a response rate of 38.87%.

The context

Members of the Nashville Power Poll are optimistic. Regarding our economic outlook as a city, the graph continues at the top and to the right. May the boom times continue.

We took it out of the park on the corporate relocation front. Assurion, Amazon, Oracle and many other small businesses have either come here in the past two years or are planning to do so, with rumors that Facebook is also looking to establish a major headquarters there. All of this comes as massive infrastructure developments take place on the east bank of the Cumberland, further facilitating the outsourcing of corporate headquarters. Many business elites feel that once a certain level of offshoring is achieved, success simply breeds more success and large-scale growth becomes inevitable. This, even as the city is grappling with signs of deterioration in its public infrastructure (transportation, garbage collection, affordable housing) which may not be able to keep pace with the massive influx of new residents.

As long as there are Power Poll members worried about all the growth, they don’t seem like a huge constituency. If we look here at the Power Poll question about a possible location on Facebook, only 16% see such a development as potentially bad. It’s not a lot of people.

Looking ahead to politics in 2022, one of the bigger stories that will emerge fairly quickly will be the redesign of the Fifth Congressional District, namely Davidson County, Dickson Country and parts of Cheatham. Long owned by U.S. Rep. Jim Cooper, the district will likely be sliced ​​like a fresh-out-of-the-oven pie, with portions going to other Congressional districts owned by Republicans. The idea, of course, is to dump Cooper and send one less Democrat to Washington from Tennessee. Significantly, a majority of Power Poll members believe that even if the district is redesigned, Cooper will somehow get a victory no matter what his new district looks like. Some politicians just know how to survive, and Jim Cooper may be one of them.

Elsewhere politically, it seems too early to bet on the survival of John Cooper, our mayor, in an election challenge in 2023. 41% believe that such a discussion is premature. However, of those willing to take risks, 27% said Cooper would be re-elected. 13% predicted the victory of the local head of the nonprofit organization Hal Cato. 19% said someone else would win. The post is said to favor Cooper, although he appears to have made few friends during the first half of his administration. He struggled to make the transition from board member to consensus builder and visionary. A lot has been thrown in Cooper’s path – COVID, 2nd Avenue bombing, tornado damage – but that doesn’t excuse the fact that as we speak the trash is not being picked up, the traffic is bad, the city’s homeless population looks worse than ever, and we haven’t even started talking about the students’ test scores.

A challenge for Cooper will come and it could very well be a doozy.

In the Middle Ages, religion permeated all aspects of society and different communities learned to live together and share the same spaces. It was not an easy task, especially for the Jewish communities which alternated permissive moments with other intolerant and repressive ones.

This situation was not an obstacle for them to leave us an enormous cultural baggage. In some aljamas science, literature, theater, philosophy, theology… have experienced a real revolution.

In the Middle Ages, astronomers, as a rule, offered a product based on astrological prediction, which did not prevent them from being used by some monarchs to make serious political decisions.

Portrait of Abraham Zacuto – Spanish Foundation for Science and Technology, Eulogia Merle

In the middle of the 15th century, Abraham Zacuto (1452-1515) was born in Salamanca, an eminent astronomer and mathematician called to revolutionize ocean navigation.

He belonged to a family of French exiles, his grandfather fled the anti-Semitic laws dictated by the Frankish king Philippe le Bel and in 1306, after crossing the Pyrenees, he settled on the Castilian plateau.

Abraham’s father served as rabbi on the banks of the Tormes, which allowed him to benefit from a privileged education and to develop his scientific concerns. Around 1475 he published ‘Composition Magna’ a complex work in which they appear astronomical tables, calculated for the meridian of Salamanca, which corrected the errors of the “Alphonsine tables”.

The interest of Jewish scientists in astronomy was due to the fact that it allowed them to accurately determine the time of the appearance of the new moon, which marked the beginning of the Sabbath and the beginning of the new year.

A scientist at the Portuguese court

Zacuto was a strong advocate of the role astronomy played in preserving health, arguing that zodiac signs influenced every part of the body and their knowledge helped physicists determine the prognosis for certain diseases.

In 1492, with the expulsion of the Jews, Zacuto emigrated to Portugal, where King John II appointed him royal astronomer and court historian. His successor to the throne, Manuel I, asks him for advice on an expedition with which he plans to reach India bypassing the southern cone of the African continent.

Apparently the Hebrew gave a favorable opinion, pointing out that the stars indicated that the success of the company depended on two brothers leading the expedition. It seems that this detail was decisive for Vasco da Gama, the senior naval captain, was chosen because he had a brother.

It is said that Zacuto prepared the maritime and astronomical calculations that made the expedition possible and that in addition, he trained the crew in the use of an astrolabe of his creation and which made it possible to determine the geographical latitude. when browsing.

In 1496, he published a version of the “Composition Magna” under the title “Almanac perpetuel” which enjoyed enormous notoriety for more than a century.

The success of the shipping company under the Portuguese flag was not an obstacle so that in 1497, in the context of a new anti-Semitic wave in Lusitanian lands, he had to emigrate to North Africa, from where he would go to Damascus. , the city that finally saw it. Pass away.

The saving eclipse

Christopher Columbus personally met Zacuto and used his maritime tables during the expedition to India. It collected the solar declination – angle formed by the sun’s rays with the plane of the equator – which made it possible to determine with enormous precision the position in relation to the equator, without having to resort to the polar star.

During the last Colombian voyage in February 1504, the fleet was left to fend for itself in Jamaica, where the natives refused to provide them with food. Zacuto’s tables predicted a lunar eclipse for February 29. The admiral assembled the chiefs of the islands and threatened to wipe out the moon if their needs were not met. Apparently, the lunar eclipse scared the natives so much that they not only respected the lives of the sailors, but also provided them with whatever they asked for.

Is a rapid antigen test sufficient or do I have to line up for a PCR? https://templodoconhecimento.com/is-a-rapid-antigen-test-sufficient-or-do-i-have-to-line-up-for-a-pcr/ Wed, 22 Dec 2021 01:57:37 +0000 https://templodoconhecimento.com/is-a-rapid-antigen-test-sufficient-or-do-i-have-to-line-up-for-a-pcr/

Christmas is approaching and I pray that on the 12th day my true love does not give me COVID.

None of us want to accidentally infect our loved ones this holiday season, but as NSW broke a new daily record today with 3,763 cases, queues at test sites and wait times for results nationwide are bonkers.

We have access to PCR tests (polymerase chain reaction tests) as well as rapid antigen tests (also called lateral flow tests) to detect SARS-CoV-2, the virus that causes COVID.

So would a rapid antigen test Will it be enough to keep Chrissy COVID-free? In this critical time before Christmas, there are obvious pros and cons for both.

PCR test – Advantages

PCR tests are used in many scientific applications, but our COVID testers use them to look for SARS-CoV-2 genetic material, which is then copied and copied billions of times to the point where it can be detected. They are up to 99% accurate because they are able to detect the virus even from the smallest amount of it on your sample.

PCR test – Disadvantages

The biggest disadvantage of the PCR test is that it is time consuming. Since laboratories use machines that process multiple samples at once, each batch takes approximately six hours from when it is placed on the plates to when the result is evident.

Samples are also not tested on site. Depending on the site you are visiting, the laboratories responsible for the tests will perform a few collections per day. So even if you arrive at, say, noon, you may have missed the morning pickup and your sample won’t be taken until the site closes at 5pm.

Right now, everyone has the same idea of ​​getting tested before the holidays and Christmas lunches. For some it’s an interstate travel requirement, for others they get pinged left, right and center as the Omicron outbreaks in NSW, ACT, QLD, and SA grow.

Some testing sites in Melbourne hit maximum capacity before they even open for the day, while others in Sydney don’t return results for five days.

There have been countless anecdotes of people queuing up to eight o’clock, and even members of our own editorial team waited up to four hours for testing this week.

Rapid Antigenic Tests – Advantages

Rapid tests are incredibly fast and easy to use.

These tests look for viral proteins rather than genetic material.

You give your nostrils a little, soft swab, you dip your tampon in a solution, that solution drip onto the test, which works like a pregnancy test.

The solution allows viral proteins to bind to antibodies which fluoresce to indicate the presence of the proteins.

You also don’t have to deal with massive test lines or waiting times for results. They take about 15 minutes to give a result, and can be done at home.

Rapid Antigenic Tests – Disadvantages

Rapid tests are much less accurate than PCR tests because no amplification process is involved to make copies of the small amount of virus you might have.

Rapid tests are only about 77% as accurate as PCR tests, according to an Australian study, and will work best if someone has a high viral load, that is, if you have been infected for several days.

If you are already having symptoms, the rapid test will be much more accurate at identifying the infection because you have a lot of lurgia in your fluids.

This means that false positives are very unlikely on rapid tests if used correctly, but false negatives are quite common for asymptomatic people who have just contracted the virus.

Rapid tests are also in high demand right now and are being sold in supermarkets and drugstores across the country because until, like PCRs, they are not free. So good luck putting on your mittens.

So when should I use which one?

You should take a PCR test if there is a known reason why you might have COVID. This includes, any symptoms, being in close contact or visiting an exposure site.

Rapid tests are considered a screening tool for prevention. It is best to consider them as a safety measure when there is no reason to suspect an infection.

They can be used before visiting a sensitive environment like a hospital or visiting your grandparents in a retirement home, before a big social event, or before going to work if you interact with others.

Which one should I choose before Christmas?

A PCR test is the only way to really sleep soundly on this before Christmas, especially if there will be vulnerable people at the dinner table, or if you’ve been a social butterfly that’s been hitting the club a lot lately.

But if not, rapid antigenic tests for everyone present could also provide you with relief. Plus if you have your gathering outside, you further reduce the risk of infection.

Good luck to all of you and be careful.

State University historian recounts the life of “most powerful telescope” to ever launch into space on December 24 https://templodoconhecimento.com/state-university-historian-recounts-the-life-of-most-powerful-telescope-to-ever-launch-into-space-on-december-24/ Mon, 20 Dec 2021 10:04:09 +0000 https://templodoconhecimento.com/state-university-historian-recounts-the-life-of-most-powerful-telescope-to-ever-launch-into-space-on-december-24/

When the US $ 10 billion James Webb Telescope launches into space from the European spaceport in French Guiana on Christmas Eve, Edmonton expert Robert Smith will observe and narrate its every move.

Content of the article

Smith, a science historian specializing in astronomy at the University of Alberta, has followed the development and design of the telescope since its beginnings in the early 2000s, and would write a book on the history of the telescope after it came into operation. far from Earth.

Smith noted that astronomers are understandably worried ahead of launch, as the telescope is expected to further accelerate our understanding of the universe as a successor to the Hubble Space Telescope, which was sent into orbit in 1990.

“Hubble has probably helped transform astronomy, so the hope is that the James Webb Space Telescope will do the same,” Smith said.

Engineers unpack, clean and prepare the James Webb Space Telescope before it is scheduled to launch into orbit, upon arrival at the Kourou, French Guiana launch site, as shown in this NASA image released on November 2, 2021 and obtained by Reuters on December 13, 2021.

Compared to the Hubble, the Webb is larger and more advanced, and will primarily observe infrared light, rather than visible or ultraviolet light, to better see and understand distant galaxies and the origins of the universe.

“I think it’s fair to say that it’s in many ways the most powerful telescope ever built,” Smith said.

This is an international collaboration between NASA, the European Space Agency and the Canadian Space Agency.

Two key Canadian elements that are part of an estimated contribution of C $ 200 million include a guidance system and a scientific instrument to examine the atmosphere of distant planets, which Smith noted is prompted by the very old question: ” is there life beyond Earth? Canadian astronomers will also benefit from a guaranteed portion of Webb observing time.

Smith said the hope is for scientists to find things they didn’t even know they were looking for.

“It’s a range of scientific possibilities, but usually with these kinds of big projects people sometimes refer to the conscious expectation of the unexpected,” Webb said, adding that projects like these are also extremely politically and technologically difficult.

The Webb Telescope will travel approximately 1.5 million kilometers – beyond the moon – meaning there will be no way for astronauts to come to the rescue with repairs. Smith said that although the rocket has a good safety record, there is always the possibility that it could explode, and because it is bent “like a piece of origami” when launched, any problem with it. its deployment – for example with the sun visor protecting its instruments – could derail its functionality.

“This is why there has been so much emphasis on testing the telescope on the ground and trying to make sure that nothing can be left to chance,” Smith said of the long-delayed launch.

He noted that the rapid development of astronomical knowledge and the telescope need to be placed in historical context, going back to when people were trying to answer similar questions about the universe, with much less powerful technology.

“It was a perfectly reasonable position in 1921 to say that no telescope had ever shown a galaxy beyond our own Milky Way galaxy, but now we have a universe full of a myriad of galaxies. , and these galaxies are actually expanding away from each other. . “
