Work as we know it will never be the same – but are we prepared for a drastic transformation of where and when we do our jobs?

Work as we know it will never be the same – but are we prepared for a drastic transformation of where and when we do our jobs?

As most knowledge workers have toiled away remotely for nearly a year, some are eager to get back to the office, while others have high hopes of being able to stay at home. Regardless of the camp you fall into, there’s one question that’s hanging over everyone: what will work actually look like on the other side of the pandemic? Will our structure revert to pre-pandemic days: 9 to 5, five days a week?

Maybe, but maybe not. Some companies are anxious to get workers back to their desks, but at the same time, employee desire is ramping for a new type of ‘hybrid’ work future – a mix of both office presence as well as some time remote.

While some of these proposals to shake up the structure of work simply focus on giving employees a little more flexibility, a few are more dramatic. Some work and productivity experts are proposing that we blow up the notion of working five days or setting standard hours and workplaces altogether. If companies and workers rally around these big ideas, they’ll create a world of work that looks very different than it did a year ago.

Working ‘3-2-2’

Three days in the office, two days remote and two days off. That’s the premise behind ‘3-2-2’, a new work-structure proposal from academics Lauren C Howe, Ashley Whillans and Jochen I Menges. The emphasis on flexibility is key here, as workers choose the set-up that works best for them and mould their days around their personal schedules. (It’s a striking contrast to China’s similarly named 9-9-6, in which employees work 9 a.m. to 9 p.m., six days a week, in a rigid structure.)

“Employees have appreciated the flexibility experienced during the pandemic, and desire more of it in the future,” says Whillans, an assistant professor in negotiations, organisations and markets at Harvard Business School. Although she expects employers to still require five days of work, generally on a Monday-through-Friday schedule, the key to the 3-2-2 model is enabling employees to pick where they work. “The exact enactment of flexibility will involve companies considering factors like Covid safety risks, employee preferences and a discussion of what kinds of activities would benefit from some in-person interaction,” she says.

Whillans adds that the 3-2-2 model would look different across different organisations – especially within larger companies in which coordinating multiple workers in person at the same time could be more complicated. But the point remains the same: honour workers’ preferences while keeping collaboration and productivity at peak.

“Every office has a different consideration set, but the general idea is to think about when to encourage employees to come to the office versus stay at home to facilitate work-life balance and increase creative and informal social interactions among employees,” she says.

Four-day workweek

The concept of a four-day workweek isn’t new – some companies have been toying with the idea, or even experimenting with it, in workplaces across the globe for a few years. The proposal has been around since the 1970s, and implemented sporadically over past few decades with mixed success. But workers are renewing the call amid the pandemic, hoping it’s a more realistic solution than ever before.

One reason is that our relationship with productivity has evolved in an unexpected way that perhaps only the pandemic could have catalysed: many are finding that while working remotely they’ve been more efficient, not needing five full days to get their work done. A survey from US jobs site FlexJobs showed that 51% of respondents reported being more productive at home – even working parents.

Part of this increased output may be the result of better focus without the buzz and clamour of colleagues. But the other element may be that there simply isn’t enough work to fill five days, and workers find ways to occupy the time just to hit their desk-hours quota (think of all the time you spend checking social media or shopping, only to quickly toggle your browser tab when your boss walks by). This isn’t a new assertion: London School of Economics anthropology professor David Graeber raised the point back in 2018 by in his book Bullshit Jobs. Plus, working more hours than necessary may also have detrimental effects, such as decreased productivity and mental-health consequences.

Advancement of the four-day workweek isn’t just a pandemic-induced dream: Covid-19 has influenced companies to take up the strategy

Advancement of the four-day workweek isn’t just a pandemic-induced dream: Covid-19 has influenced a few companies to take up the strategy.

In December, Unilever New Zealand implemented a four-day workweek trial. “Our employees will work 80% of the time, while retaining 100% of their salaries and deliver 100% of their KPIs/output,” says Nick Bangs, general manager of Unilever New Zealand. There’s no “overarching template”, he adds, so workers choose their day off. The purpose, he says, is creating a “new productivity mindset”, and encourage more flexibility and better health.

A new reality?

These two approaches represent very different re-thinks of how we work: 3-2-2 emphasises flexibility across a 40-hour week; four-day workweek maintains structure, though with less time to be on. Is one more likely to happen than another?

Of course, it’s tough to say; ongoing impacts of the pandemic will continue to shift not only our thinking and values, but also our expectations of employers. In some ways, 3-2-2 may seem more ‘realistic’ as workers demand more flexibility, which 3-2-2 offers in spades. But we haven’t quite seen the proposal in action at scale – whereas the four-day workweek is already in motion for some companies, with others considering taking up the approach.

But there are also people who hate the idea of dismantling the typical workday structure all together, saying changes may let competition get ahead, leave clients waiting for responses, damage workers’ health and even sink the corporate world as we know it.

In the past, some firms that have embraced flexible, remote working have found the move disastrous for their output and bottom lines; in 2013, Yahoo CEO Marissa Mayer actually rolled back telecommuting initiatives, and forced employees back into traditional structures.

Similarly, the four-day workweek has virulent critics. Speaking on BBC’s Business Daily in December, Marc Effron, president of global HR company The Talent Strategy Group, said, “It feels like we’re somehow rewarding people for being inefficient by saying, ‘Well, because you were wasting so much time before, now that you’ve found some of that time by squeezing it into a four-day workweek, we’ll allow you just to work those four days’.” Simply, he posits that if workers can do five days of work in four, they’re not putting in 100% effort to begin with.

And even advocates for both 3-2-2 and the four-day workweek concede the plans aren’t without their wrinkles and caveats.

Whillans says that some companies will face challenges others won’t. “Organisations will have to think carefully about how to structure the in-office time so that the right people from the right teams are coming to work at the same time… Additionally, it will be up to leaders and organisations to coordinate schedules so no one is being left out.”

And Unilever’s Bangs says that in order to stick with their new four-day approach, there needs to be a visible upside, otherwise they’ll end the experiment, currently set to finish in December 2021. “This trial is not about compromising business growth for the benefit of wellbeing, or vice versa. For this to be deemed successful, we need great business results, our people telling us they have the mental and physical energy to bring the best version of themselves to work and our customers continuing to receive the same level of excellent service we pride ourselves on.” Regardless of what happens in New Zealand, however, Unilever CEO Alan Jope says that the company will never go back to the five-day in-office structure they had pre-pandemic, which he added in a Reuters news conference «seems very old-fashioned now».

Like many elements of our daily lives, the answer is still up in the air. But among the questions, one thing seems all but certain: the way we work will never be quite the same.

Mundo: Descubren una supertierra casi tan antigua como el Universo

Descubren una supertierra casi tan antigua como el Universo

La supertierra recientemente descubierta orbita una de las estrellas más remotas del cosmos y tiene unos 10.000 millones de años.

¿Cuánto puede vivir un planeta? A tenor de este descubrimiento, está claro que pueden vivir mucho tiempo.

La misión TESS de la NASA (Satélite de reconocimiento de exoplanetas en tránsito) cuyo objetivo es descubrir nuevos planetas, ha permitido a los científicos localizar un exoplaneta caliente y rocoso, bautizado TOI-561b.

Se trata de una supertierra que se encuentra orbitando alrededor de una de las estrellas más antiguas, una enana naranja llamada TOI-561, situadas en nuestra Vía Láctea.

La TOI-561b se encuentra a solo 280 años luz de distancia de la Tierra, es un 50% más grande que el planeta Tierra y tiene el triple de su masa.

Calculamos que su densidad era la misma que la de nuestro planeta. Esto es sorprendente porque cabría esperar que la densidad fuera mayor. Esto es consistente con la noción de que el planeta es extremadamente antiguo. Su existencia muestra que el universo ha estado formando planetas rocosos casi desde su inicio“, informan los científicos.

Un dato curioso es que esta supertierra gira alrededor de su estrella anfitriona en una órbita de 10,5 veloces horas. Comparando con el planeta Tiera, necesita menos de medio día terrestre para realizar su órbita completa.

Por cada día que estás en la Tierra, este planeta orbita su estrella dos veces“, detalla Stephen Kane, astrofísico planetario de la Universidad de California en Riverside.

Las temperaturas de su superficie superan los 1.700 ° C, lo que hace imposible la vida tal y como la conocemos sobre este planeta.

Las estrellas en esta región son químicamente distintas, con menos elementos pesados como el hierro o el magnesio que están asociados con la construcción de planetas“, detalla Lauren Weiss, investigadora postdoctoral de la Universidad de Hawái y coautora del trabajo que publica la revista The Astronomical Journal.

Los elementos más pesados ​​del cosmos se forjan en los corazones de las estrellas, en las supernovas al final de la vida de una estrella masiva y en las colisiones entre estrellas muertas igualmente masivas. Como resultado de ello, las estrellas más antiguas del universo son muy pobres en metales. Y, en cuanto a los planetas, a medida que estos envejecen, se vuelven menos densos porque no hay tantos elementos pesados ​​disponibles como en el momento en el que se formaron.

Aunque es poco probable que este planeta en particular esté habitado hoy en día, puede ser un presagio de muchos mundos rocosos aún por descubrir alrededor de las estrellas más antiguas de nuestra galaxia“, concluye Kane.

Estas son las pautas para ver la ‘triple conjunción’ de Mercurio, Júpiter y Saturno este domingo

Estas son las pautas para ver la ‘triple conjunción’ de Mercurio, Júpiter y Saturno este domingo

Los tres cuerpos formarán un «triángulo pequeño y ordenado» en el cielo oeste-suroeste, que aparecerá el domingo entre 30 y 45 minutos después de la puesta del sol.

El esperado triángulo que formará la conjunción de Júpiter, Saturno y Mercurio finalmente llegará este domingo y los expertos han ofrecido algunos consejos para poder observar este fenómeno espacial.

Según el sitio Space.com, los tres cuerpos formarán un «triángulo pequeño y ordenado» en el cielo oeste-suroeste, que aparecerá mañana entre 30 y 45 minutos después de la puesta del sol.

Como referencia, Júpiter aparecerá en la parte superior del triángulo, brillando aproximadamente dos veces y media más que Mercurio y 10 veces más brillante que Saturno. En esta ocasión, aunque Mercurio es el más pequeño de los tres, será cuatro veces más brillante que el único planeta con un sistema de anillos visible desde la Tierra.

Entre otras recomendaciones, los especialistas aconsejan el uso de binoculares para poder apreciar mejor la llamada ‘triple conjunción’. Por otra parte, es mejor evitar las zonas muy iluminadas o con otros obstáculos como árboles y edificios, que podrían impedir la visibilidad del cielo despejado.

Esta podría ser la última vista nocturna de Júpiter y Saturno. Primero desaparecerá el planeta de los anillos y después, el más grande del sistema solar a mediados de enero.

Mientras tanto, el primer mes de este año seguirá sorprendiendo a los aficionados de la astronomía. El 11 de enero se podrá ver a la Luna creciente muy delgada junto con Venus, y las noches del 20 y 21, Marte estará cerca del satélite natural de la Tierra.

Además, del 21 al 28 de enero, Mercurio será visible fácilmente en el oeste-suroeste, unos 30 minutos después de la puesta del Sol.

Mundo: Un distante exoplaneta arroja luz sobre la hipótesis del «noveno planeta»

Un distante exoplaneta arroja luz sobre la hipótesis del «noveno planeta»

El exoplaneta, un gigante con 11 veces la masa de Júpiter denominado HD106906 b, fue descubierto en 2013 con los telescopios Magallanes del observatorio chileno de Las Campanas y desde el principio llamó la atención por sus peculiaridades.

Con ayuda del telescopio espacial Hubble los astrónomos lograron en 14 años de mediciones desentrañar su peculiar órbita: elíptica pero extremadamente alargada y muy inclinada (a 30 grados del plano en el que se mueven todos los demás planetas del sistema).

Además, establecieron que el exoplaneta cuenta con un período de traslación de 15.000 años en torno a la pareja de jóvenes y brillantes estrellas, de las que separa una distancia media 730 veces la existente entre la Tierra y el Sol.

Se trata de la primera vez que expertos han sido capaces de medir el movimiento de un exoplaneta similar a Júpiter que está orbitando tan lejos de sus estrellas y más allá de un disco de asteroides.

«Esto suscitó todo tipo de preguntas sobre cómo HD106906 b acabó tan lejos y en una órbita tan inclinada», explicó Meiji Nguyen, director del estudio e investigador de la Universidad de California, Berkeley.

Para contestar a estas preguntas se planteó la siguiente teoría: el planeta se formó mucho más cerca de sus estrellas, pero su órbita se vio afectada por un disco de gas, lo que le llevó primero hacia su pareja de estrellas y luego, por la fuerza gravitacional, a salir expulsado en una extraña inclinación.

Si no llegó a escapar totalmente de su sistema planetario, prosigue la hipótesis, fue por el paso de una estrella que logró estabilizar la órbita del planeta (los expertos cuentan con varias candidatas para este papel).

La explicación, prosigue el estudio, es especialmente relevante porque serviría para completar algunos de los huecos de la hipótesis del «noveno planeta» del sistema solar, que postula que hubo un planeta más en nuestro vecindario.

Según este estudio, el «noveno planeta» habría sido expulsado del corazón del sistema solar al interaccionar con Júpiter y habría ido a parar más allá de Plutón y del cinturón de asteroides de Kuiper.

«Es como si tuviéramos una máquina del tiempo de nuestro sistema solar que fuese para atrás 4.600 millones de años para ver que pudo haber pasado», explicó otro miembro del equipo investigador, Paul Kalas de la Universidad de California, Berkeley.

Por el momento la hipótesis del «noveno planeta» sólo cuenta con evidencias circunstanciales, como los pequeños cuerpos celestes más allá de Neptuno que se mueven en órbitas inusuales y cuya configuración, según algunos astrónomos, se explicaría por ese «noveno planeta».

«Pese a que hasta la fecha no se ha detectado el noveno planeta, la órbita del planeta puede ser inferida a base de su efecto en varios objetos en el sistema solar exterior», explica Robert de Rosa, del Observatorio Meridional Europeo (ESO). «Las predicciones de la órbita del noveno planeta son similares a las que vemos en HD 106906b», agregó.

Ecocide: Should killing nature be a crime?

Ecocide: Should killing nature be a crime?
From the Pope to Greta Thunberg, there are growing calls for the crime of “ecocide” to be recognised in international criminal law – but could such a law ever work?

In December 2019, at the International Criminal Court in the Hague, Vanuatu’s ambassador to the European Union made a radical suggestion: make the destruction of the environment a crime.

Vanuatu is a small island state in the South Pacific, a nation severely threatened by rising sea levels. Climate change is an imminent and existential crisis in the country, yet the actions that have caused rising temperatures – such as burning fossil fuels – have almost entirely taken place elsewhere, to serve other nations, with the blessing of state governments.

Small island states like Vanuatu have long tried to persuade large powerful nations to voluntarily reduce their emissions, but change has been slow – so ambassador John Licht suggested that it might be time to change the law itself. An amendment to a treaty known as the Rome Statute, which established the International Criminal Court, could criminalise acts that amount to ecocide, he said, arguing “this radical idea merits serious discussion”.

Ecocide – which literally means “killing the environment” – is an idea that seems both impossibly radical and eminently reasonable. The theory is that no one should go unpunished for destroying the natural world. Campaigners believe the crime should come under the jurisdiction of the International Criminal Court, which can currently prosecute just four crimes: genocide, crimes against humanity, war crimes and crimes of aggression.

If something’s a crime, we place it below a moral red line – Jojo Mehta

While the International Criminal Court can already prosecute for environmental crimes, this is only possible within the context of these four crimes – it does not place any legal restrictions on legal harms that occur during times of peace. While individual countries have their own rules and regulations to prevent such harms, ecocide campaigners argue that mass environmental destruction will continue until a global law is in place.

This wouldn’t be the fluffy and arguably toothless rulemaking that often emerges from international processes – such as the Paris Agreement on climate change, where countries set their own emissions reductions targets. By adding a fifth crime of ecocide to the Rome Statute of the International Criminal Court, the perpetrators of environmental destruction would suddenly be liable to arrest, prosecution and imprisonment.

But it would also help to create a cultural shift in how the world perceives acts of harm towards nature, says Jojo Mehta, co-founder of the Stop Ecocide campaign.

“If something’s a crime, we place it below a moral red line. At the moment, you can still go to the government and get a permit to frack or mine or drill for oil, whereas you can’t just get a permit to kill people, because it’s criminal,” she says. “Once you set that parameter in place, you shift the cultural mindset as well as the legal reality.”

Campaigners believe the crime of ecocide should only apply to the most serious harms, encompassing activities like oil spills, deep-sea mining, industrial livestock farming and tar sand extraction. In 2010, Polly Higgins, a British barrister, defined ecocide as “extensive damage… to such an extent that peaceful enjoyment by the inhabitants of that territory has been or will be severely diminished.”

The mother of all battles is international: to ensure that this term is enshrined in international law – Emmanuel Macron

Last year, Higgins died aged 50, after being diagnosed with cancer. It was a blow for the ecocide movement – she had been its leading legal light and fiercest advocate, selling her house and giving up her high-paying job in order to dedicate her life to the campaign. Despite her passing, that the movement now appears to be gaining momentum. After decades of existing at the radical fringes of the environmental movement, ecocide is now being discussed by parliamentarians and leaders across the world.

Among them is Emmanuel Macron, the president of France, who has become one of ecocide’s highest profile supporters. Earlier this year, more than 99% of the French citizens’ assembly, a group of 150 people selected by lot to guide the country’s climate policy, voted to make ecocide a crime. That prompted Macron to announce that the government would consult with legal experts on how to incorporate it into French law. But he went further. “The mother of all battles is international: to ensure that this term is enshrined in international law so that leaders… are accountable before the International Criminal Court,” he responded to the assembly.

Elsewhere in Europe, Belgium’s two Green parties have introduced an ecocide bill that proposes addressing the issue at both a national and international level – an idea that also has support among Swedish parliamentarians. “We have all the conventions, we have all the goals. But the beautiful visions must go from paper into action,” said Rebecka Le Moine, the Swedish MP who submitted a motion to her national parliament. “If these actions should be anything more than goodwill or activism, it must become law.”

Pope Francis has also called for ecocide to be recognised as a crime by the international community, and Greta Thunberg has backed the cause too, donating €100,000 (£90,000) in personal prize winnings to the Stop Ecocide Foundation.

The International Criminal Court has itself placed increasing emphasis on prosecuting environmental crimes within the limitations of its existing jurisdiction. A 2016 policy paper on case selection highlighted the court’s inclination to prosecute crimes involving illegal natural resource exploitation, land grabbing and environmental damage. While this doesn’t change the status quo, it “could be regarded as an important step towards the establishment of a crime of ecocide under international law”, according to one paper.

Even so, the concept of ecocide has its limitations. Richard Whyte, professor of socio-legal studies at the University of Liverpool and author of a book called Ecocide, warned that an international law would not be a silver bullet that eradicates environmental destruction. Corporations cannot be prosecuted under international criminal law, which only applies to individuals, Whyte points out – and bringing down a CEO may not actually rein in the business itself.

“It’s really important to change our language and the way we think about what’s harming the planet – we should push through this crime of ecocide – but it’s not going to change anything unless, at the same time, we change the model of corporate capitalism,” he says.

While there is still a long way to go before ecocide could be recognised as an international crime, the movement continues to gather pace, says Rachel Killean, a senior lecturer in law at Queen’s University Belfast, who has recently written about alternative ways in which the International Criminal Court could address environmental harms.

“You can never say never – and it’s gaining momentum that we maybe would never have imagined previously – but the challenges are still so significant. First of all, you have political resistance. I think the chance of an assembly of state parties agreeing to an additional crime is unlikely, particularly one that might curb economic expansion,” she says.

An international law on ecocide would also be difficult from a legal perspective, adds Killean – lawyers would have to ensure that there were sufficient grounds for prosecution.

 “If you think about all the parts of the criminal prosecution, you need to have an individual – so who’s the individual that’s responsible for ecocide? There needs to be intention – so how do you prove intention for the destruction of a territory? All these different things that build up a criminal trial become really complicated when you’re thinking about ecocide.”

Campaigners like Mehta understand these difficulties. Her campaign group, Stop Ecocide, is currently pulling together a panel of top international lawyers to write a “clear and legally robust” definition of ecocide that countries could propose at the International Criminal Court.

Once that’s in place, the next step would be for a country to back it at The Hague. While Vanuatu has raised the issue, it did not submit a formal proposal to amend the Rome Statute, and whether there will be a government brave enough to do so remains an open question – leading on such an issue requires a certain level of diplomatic clout. Mehta believes that such a move is becoming more likely due to the growing number of governments that have expressed their theoretical support. “There’s safety in numbers,” she says. “It’s less of a political risk.”

But the journey wouldn’t end there. Once a proposal is submitted, it would have to be adopted by a two-thirds majority vote – in practice, that means it needs the support of 82 countries. No country has veto power, and all nations have the same voting power regardless of size or wealth. It’s a process that Mehta envisages taking anywhere between three and seven years.

Whether or not the process happens so quickly, or if it even happens at all, ecocide has proved to be a powerful idea. It has crystallised a concept that often gets lost in discussions of policy and technology: that many see that there is a moral red line when it comes to destroying the environment. And it is a reminder that it is not a victimless act: when forests burn and oceans rise, humans are suffering around the world. Moreover, the perpetrators of these acts are not blameless. For campaigners like Mehta, criminalising ecocide is a way to call time on the destruction of the Earth’s ecosystems and those who live in them.

Hubble Examines Massive Metal Asteroid Called ‘Psyche’ That’s Worth Way More Than Our Global Economy

Hubble Examines Massive Metal Asteroid Called ‘Psyche’ That’s Worth Way More Than Our Global Economy

A new study by the Hubble Space Telescope has revealed a clearer picture than ever before of one of the most intriguing and most valuable asteroids we know of.

It’s also one that NASA is planning to visit in 2026.

Here’s everything you need to know about “16 Psyche.”

What and where is ‘16 Psyche?

About 230 million miles/370 million kilometers from Earth, Psyche—as it’s commonly known—is one of the most massive objects in the Solar System’s main asteroid belt orbiting between Mars and Jupiter.

It’s about 140 miles/226 kilometers-wide and—unlike most asteroids, which are rocky or icy—Psyche appears to be metallic.

In fact, it’s so dense and metallic that Psyche is thought to be the leftover core of a planet that failed during its formation—a “protoplanet.”

What is ‘16 Psyche’ made of?

“We’ve seen meteorites that are mostly metal, but Psyche could be unique in that it might be an asteroid that is totally made of iron and nickel,” said Dr. Tracy Becker, a planetary scientist at the Southwest Research Institute in in San Antonio, Texas, and author of the new paper published in the Planetary Science Journal this week.

Iron and nickel are often found in metallic meteorites and in the dense metal cores of planets. “Earth has a metal core, a mantle and crust,” said Becker.

Psyche is truly a one-of-a-kind object in the Solar System.

How much is ‘16 Psyche’ worth?

Some think that the metals that comprise Psyche could make be worth about $10,000 quadrillion. The global economy was worth about $142 trillion in 2019.

What happened to ‘16 Psyche?’

“It’s possible that as a Psyche protoplanet was forming, it was struck by an-other object in our solar system and lost its mantle and crust,” said Becker.

‘16 Psyche’ was studied in the infrared by the Hubble Space Telescope.

‘16 Psyche’ and the Hubble Space Telescope

Becker’s study had the Hubble Space Telescope observe the asteroid at two specific points in its rotation to view both sides of Psyche. It also viewed the asteroid in ultraviolet wavelengths of light to get as much detail as possible of its surface. “We were able to identify for the first time on any asteroid what we think are iron oxide ultraviolet absorption bands,” said Becker. “This is an indication that oxidation is happening on the asteroid, which could be a result of the solar wind hitting the surface.”

The solar wind is a stream of charged particles from the Sun’s hotter outer atmosphere called its corona. Often called “space weather,” it’s also what causes aurora at Earth and could, at Psyche have caused excessive “space weathering.”

A surface of pure iron?

Becker saw that the asteroid’s surface could be mostly pure iron, though noted that the presence of even a small amount of iron could dominate ultraviolet observations, and in practice it could just be that 10% of the surface is actual iron.

However, while observing Psyche, the asteroid appeared increasingly reflective at deeper UV wavelengths. “This is something that we need to study further,” said Becker. “This could be indicative of it being exposed in space for so long. This type of UV brightening is often attributed to space weathering.”

However, what Becker’s paper makes very clear is that while it’s tricky to quantify the amount of iron that may be present on the surface of Psyche, it’s a unique object so scientists cannot compare it with anything else.

NASA's orbiter will spend 21 months in orbit mapping and studying Psyche's properties.

NASA and SpaceX’s mission to 16 Psyche

The only way we’ll ever get to see a close-up of what the core of a planet is really like is to pay a visit to Psyche. That’s exactly what NASA is planning to do.

Due to launch in August 2022 from Florida’s Kennedy Space Center atop a SpaceX Falcon Heavy rocket, NASA’s Psyche mission is part of its Discovery Program of low-cost robotic space missions.

The orbiter is due to arrive at Psyche in January 2026 to begin at least 21 months in orbit mapping and studying the asteroid’s properties.

“To understand what really makes up a planet and to potentially see the inside of a planet is fascinating,” said Becker, who describes Psyche and other asteroids as the building blocks of the Solar System. “Once we get to Psyche, we’re really going to understand if that’s the case, even if it doesn’t turn out as we expect … any time there’s a surprise, it’s always exciting.”

Petróleo cae casi 3% ante alza de casos de covid-19 y temores sobre la demanda

Petróleo cae casi 3% ante alza de casos de covid-19 y temores sobre la demanda

REUTERS

El precio del petróleo bajaba cerca de 3 por ciento, prolongando las pérdidas de la semana anterior ante el aumento de casos de coronavirus SARS-CoV-2, que causa la enfermedad covid-19 en Estados Unidos y Europa, lo que incrementa la preocupación sobre la demanda de combustible, aunado a una mayor producción que afectaba a la confianza.

El referencial internacional Brent perdía 1.11 dólares, o 2.66 por ciento, a 40.66 dólares el barril, mientras que el West Texas Intermediate en Estados Unidos (WTI) también cedía 1.11 dólares, o 2.79 por ciento, a 38.74 dólares el barril. El Brent retrocedió 2.7 por ciento y el WTI entregó 2.5 por ciento la semana pasada. https://www.milenio.com/negocios/petroleo-ve-impactado-alza-casos-covid-19-eu-europa

Estados Unidos reportó su mayor número hasta la fecha de nuevas infecciones de coronavirus en dos días hasta el sábado, mientras que los nuevos casos en Francia tocaron un récord de más de 50 mil el domingo, subrayando la gravedad del brote. En lo referente al suministro, la Corporación Nacional del Petróleo de Libia puso fin el viernes a la fuerza mayor a las exportaciones de dos puertos clave y dijo que la producción alcanzará el millón de barriles por día (bpd) en cuatro semanas, un aumento más rápido del previsto por analistas.

«Los nuevos barriles de crudo libio llegan en un momento en que el mercado petrolero acaba de enfrentar la decepción por el panel ministerial de la OPEP+ recientemente concluido, en el que la organización no hizo nuevas propuestas de política», dijo Avtar Sandu, de Phillip Futures en Singapur.

La OPEP+, un grupo de productores que incluye a la Organización de Países Exportadores de Petróleo (OPEP) y Rusia, tiene previsto incrementar su bombeo en 2 millones de bpd en enero de 2021, tras recortar su producción en una cantidad récord más temprano en el año. El presidente ruso, Vladimir Putin, indicó la semana pasada que podría acceder a extender las reducciones de bombeo de la OPEP+.
