Dawn Breaks Over Earth: A Spectacular Sunrise Seen From the Space Station – SciTechDaily

Astronaut photograph of the Sun rising above Earths horizon captured from the International Space Station on September 29, 2023.

Astronauts aboard the International Space Station are uniquely positioned to capture striking photos of the Sun and Earth.

As the International Space Station orbited over the southern Indian Ocean, an astronaut looked eastward and captured this photo of the Sun rising above Earths horizon.

This edge-on photo of Earths limb reveals several atmospheric layers. The lowest layer, known as the troposphere, appears orange and red as these wavelengths of light are scattered by particles of dust, smoke, and smog. Directly above the troposphere is the stratosphere. This blue layer is usually cloud-free and extends as much as 50 kilometers (30 miles) above Earths surface. The region directly above the stratosphere is known as the mesosphere.

The Sunthe focal point in this imageis front and center in NASAs Heliophysics Big Year. This big year celebration began with the annular solar eclipse in October 2023 and continues with a total solar eclipse in April 2024. It concludes with the Parker Solar Probes closest approach to the Sun in December 2024.

The total solar eclipse in April 2024 will pass over Mexico, the United States, and Canada. In addition to putting on an impressive show, the eclipse offers research opportunities including the chance for scientists to study the Suns effect on Earths ionosphere. This is the region spanning from about 80600 kilometers (50400 miles) above Earths surface, overlapping with the top of the atmosphere and the beginning of space. It is where the space station and other satellites in low Earth orbit hang out, and where radio and GPS signals bounce around.

During a solar eclipse, astronauts on the space station can sometimes see the Moons shadow passing over Earth. Views of sunrises are much more common, with astronauts witnessing as many as 16 sunrises every 24 hours.

Astronaut photograph ISS070-E-1178 was acquired on September 29, 2023, with a Nikon D5 digital camera using a focal length of 170 millimeters. The image was provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at Johnson Space Center. The image was taken by a member of the Expedition 70 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public and to make those images freely available on the Internet.

ARGENTINA SNUBS BRICS AS ITS FIREBRAND POPULIST LEADER TAKES POWER – The Sunday Guardian

Milei has already begun to backtrack on some of the key proposals of complete dollarisation and shutting down Argentinas central bank, arguing that it will take time to achieve given the economic crisis.

LONDON

Well, that didnt last long. We will not join the BRICS, said Diana Mondino, who will serve as Argentinas top diplomat in the government of President-elect Javier Milei when he is sworn into office today. Only last August at the summit in Johannesburg, members of the bloc consisting of Brazil, Russia, India, China and South America invited Argentina, along with five other countries, to become new members. It was planned that Argentinas membership would have taken effect three weeks tomorrow, along with Egypt, Ethiopia, Iran, Saudi Arabia and United Arab Emirates. Now the expanded BRICS will consist of ten countries on 1 January 2024 instead of the planned eleven. Although Mondinos announcement appeared to be a bolt from the blue, no-one who followed the far-right populist Mileis election campaign would have been surprised. During the campaign he criticised Brazilian leader Luiz Inacio Lula da Silva many times, labelling him an angry communist and socialist with a totalitarian vocation. Brazil is Argentinas biggest trading partner. Milei also harshly criticised China, comparing the government to an assassin and threatening to cut off ties. I would not promote relations with communists, whether its Cuba, Venezuela, North Korea, Nicaragua, or China, he said in an August interview on Bloomberg Television. China has been a major investor in the Argentine economy and Beijing had been concerned that an anti-China administration in Buenos Aires could harm Chinas extensive interests in the country, ranging from mining to a secretive space station China operates in Argentina. Knowing Mileis anti-Beijing stance, President Xi Jinping had bet heavily on the Peronists candidate, former Economic Minister Sergio Massa, even releasing a $6.5 billion in yuan into the two countries bilateral currency swap account just before voting took place, hoping to help prop up the Argentine economy and prevent further currency devaluation prior to the election. It turned out to be a bad bet by Xi.

In the event, Javier Milei won by a surprisingly large margin of twelve points in the presidential election on 19 November. Now the big question is whether he can turn around the countrys crisis-stricken economy. Milei campaigned on the promise of deep spending cuts and dollarisation, the idea of replacing the Argentinian peso with the US dollar. In promising shock therapy for Argentina, Milei also campaigned on plans to shut the central bank and slash spending. But all this will be hard to implement given the countrys political and economic realities. After the result of the poll was announced, Milei made his customary defiant speech. The model of decadence has come to an end and theres no going back, he declared. He then raised the challenges that faced the country: we have monumental problems aheadinflation, lack of work and poverty. The situation is critical and theres no place for tepid half-measures. In fact, Mileis challenges are even greater than monumental. Government coffers are empty and theres also the not-so-small matter of a $44 billion debt program with the International Monetary Fund. The country has a dizzying array of capital controls and a humongous inflation rate nearing 150 percent. In an attempt to curb the runaway inflation, in October Argentinas central bank had raised the benchmark rate of interest to an astonishing 118 percent. Mileis victory marked a profound rupture in Argentinas system of political representation. The 53-year-old economist and former TV personality shattered the hegemony of the two leading political forces that have dominated the countrys politics since the 1940s: the Peronists on the left and Together for Change on the right. His opponent, the 51-year-old Peronist candidate and experienced wheeler-dealer, Sergio Massa, had sought to appeal to voter fears about Mileis plans to cut back the size of the state as well as his volatile character. In the early part of the campaign Milei outrageously carried a chainsaw as a symbol of his planned cuts, but decided to shelve it in the weeks before voting took place in order to help boost his moderate image. Massas appeal went unheeded.

So now the hard work begins. In recent years, Argentina has lurched from one profound economic crisis to another. The country is also currently in recession, fuelled by a three-year drought that has done much damage to agricultural exports. The harvest of soybeans, one of the nations biggest exports, is barely one-third of five years ago. All this is exacerbating the cost of living crisis, which has already driven poverty levels above forty percent. Meanwhile, Argentina holds the unenviable position of being number one on the debtor list of the IMF. Stringent currency controls have made it hard to move money out of the country, which has led to a black market in pesos whose value has also been falling sharply. During election debates, Milei argued that by stopping the central bank from printing more money, which it has relied on to finance public spending, and replacing the peso with the US dollar, inflation would be cured. Sceptical critics claimed that this would be impractical as the central bank would lose control over monetary policy, and in any case Argentina has insufficient currency reserves to implement the plan. Mileis dollarisation plan is also a worry for economists; but political opposition and Argentinas lack of foreign reserves make the chances of that happening narrow at best. As so often when populists meet reality, since his victory Milei has already begun to backtrack on some of the key proposals of complete dollarisation and shutting down Argentinas central bank, arguing that it will take time to achieve this given the economic crisis. His pragmatism is also likely to extend to foreign policy.

While Mileis control over Argentinas economic fate is limited, hell have an element of free reign over the countrys foreign policy. During the campaign he announced some very large shifts in Argentinas relationships with other countries. The outgoing President Alberto Fernandez had pursued a foreign policy aligned with many of his leftist counterparts in South America, including Brazilian President Lula da Silva and Colombian President Gustavo Petro. Fernandez built political alliances through the Community of Latin American and Caribbean States and recently convinced the BRICS member states to make Argentina one of the countries included in the organisations first expansion. The far-right populist Milei plans to undo all that.

During the election campaign, Milei insisted that his foreign policy would strengthen ties with the free world and avoid contact with communist countries. After the primaries, he indicated that he would freeze official trade relations with China, but his campaign rhetoric is already giving way to pragmatism. Since his win, Milei has softened his stance on Beijing in view of China being Argentinas second largest trade partner, accounting for nearly ten percent of all Argentinian exports. He has also sought to mend fences with Brazils President Lula by inviting him to todays inauguration, an invitation which Lula snubbed by nominating his Foreign Minister Mauro Vieira in his place. Maybe its also because Lulas arch rival, former Argentine President Jair Bolsonaro, has accepted an invitation to attend. Javier Milei is hardly the first of that countrys leaders to come to power boldly promising a cure for Argentinas extensive economic and social problems. For decades, new leaders on both left and right of the political spectrum have come to power with a radical reform programme breaking with the past. None of them have had more than temporary success in taking the country out of the malaise that has characterised most of its modern history. Will the libertarian populist Milei break the mould? Probably not. He might even change his mind and decide to join the expanded BRICS!
