El prototipo de la nueva cápsula espacial tripulada china termina con éxito su primera misión

Tras ser puesta en órbita el pasado día 5 por el primer cohete Larga Marcha 5B el prototipo de la nueva cápsula espacial tripulada china aterrizaba a las 7:49 del 8 de mayo de 2020. La duración de la misión fue de dos días y 19 horas. Alcanzó una altitud máxima de 8.000 kilómetros. Hizo la reentrada simulando volver de una misión a la Luna.

Según las autoridades chinas la misión ha sido un éxito y ha permitido hacer una primera prueba de los sistemas de a bordo de la cápsula. También ha permitido comprobar el correcto funcionamiento de sus paracaídas y del airbag que usa para amortiguar el impacto final durante el aterrizaje. Y De paso se han ejecutado algunos experimentos en su interior.

También ha permitido a los equipos de tierra practicar la recuperación de la cápsula y en el futuro permitirá probar su capacidad de reutilización parcial. Para ello esta misma cápsula volverá a ser lanzada al espacio con un nuevo escudo térmico.

La nueva cápsula, en la configuración que fue lanzada, mide nueve metros de altura incluyendo el módulo de servicio, que no es reutilizable, y su peso es de 21 toneladas. Hay otra versión, con un módulo de servicio más pequeño y de tan sólo 14 toneladas que será utilizada para misiones a órbita baja terrestre. Es capaz de llevar seis astronautas, o bien una combinación de astronautas y carga. No está previsto que sustituya a las cápsulas Shenzhou, sin embargo; se usará una u otra según los objetivos de la misión.

No hay confirmación oficial pero se cree que el nombre de la nueva cápsula es Xinyidai Zairen Feichuan - Shiyan Chuan, nave espacial tripulada de nueva generación, XZF-SC.

La que corrió peor suerte fue una cápsula de retorno de muestras experimental que fue liberada desde la parte trasera exterior del módulo de servicio de la XZF-SC. Con unas dimensiones de aproximadamente 1,2 metros de largo y 60 centímetros de ancho usa un escudo térmico hinchable de tres metros para la reentrada. Esto permitiría traer muestras de vuelta desde la futura estación espacial china. Pero, al menos en este primer intento, no lo consiguió.

China lanza con éxito su primer cohete Larga Marcha 5B

El programa espacial tripulado chino ha dado un importante paso adelante con el lanzamiento con éxito del primer cohete Larga Marcha 5B. Es la versión adaptada del Larga Marcha 5 para el lanzamiento de su nueva nave espacial tripulada y de los módulos de la estación espacial.

En este primer lanzamiento ha puesto en órbita una versión de prueba de la nueva cápsula tripulada, que ascenderá usando sus motores hasta alcanzar los 8.000 kilómetros de altitud. Desde ahí simulará una reentrada de una misión más allá de la órbita baja terrestre. La misión durará tres días y permitirá poner a prueba sus sistemas así como el despliegue de los paracaídas, el aterrizaje, que usa un airbag para amortiguar el impacto final, y la recuperación de la cápsula una vez en tierra. También permitirá probar su capacidad de reutilización parcial, reemplazando el escudo térmico para una futura misión.

Queda aún por analizar los datos obtenidos durante el lanzamiento pero si todo ha ido tan bien como parece China podría lanzar el primer módulo de la estación espacial a principios de 2021.

Aunque antes un Larga Marcha 5 mandará rumbo a Marte la misión Tianwen-1, compuesta por un orbitador y un rover. Será en la ventana de lanzamiento de julio de 2020.

Es, además, una buena noticia por partida doble porque en menos de un mes habían fallado dos lanzamientos chinos, el de un Larga Marcha 3B el pasado 9 de abril y el de un Larga Marcha 7A el 16 de marzo.

The incredible value of the iPhone SE in 5 simple charts

As we made clear in our iPhone SE review, the best feature of Apple's new iPhone is the price. By essentially taking an iPhone 8 and swapping out its processor for the company's latest-and-greatest A13 Bionic, Apple is able to profitably sell a $399 phone that gives a lot of bang for the buck.

How good of a value is it, really? Perhaps a few charts will make everything more clear. By taking performance metrics and dividing it by the base starting price for every new iPhone you can buy, we are able to get a measure of performance-per-dollar.

Prosser: Apple Watch will soon be able to detect oncoming panic attacks

You could soon detect an oncoming panic attack with Apple Watch.

What you need to know

  • A new rumor claims Apple is bringing mental health features to Apple Watch.
  • Leaker Jon Prosser says the Watch will soon be able to detect panic attacks.
  • The feature could be coming to the Apple Watch as soon as this year.

Apple is set to unveil watchOS 7 at its virtual WWDC keynote event on June 22nd, but we may already have an idea of at least one feature that may be coming to the latest update for the software that powers the Apple Watch.

Reported by MacRumors, leaker Jon Prosser was on the Geared Up Podcast when he spoke about a new feature that could be coming to the Apple Watch as soon as this year. Prosser said that Apple is looking to bring "mental health capabilities" to the Apple Watch, such as the ability to detect an oncoming panic attack.

"What their biggest focus on is right now and I hope it comes this year, it might come next year, but I hope it's coming to WWDC is mental health capabilities. Where they can take the oxygen levels in your blood with your heart rate and determine if you're hyperventilating. They can identify a panic attack before it happens and warn you on your watch. Especially if you're driving, they'll ask you to pull over and they'll offer breathing exercises once you get pulled over."

Apple is rumored to be working on blood oxygen monitoring for a future version of Apple Watch, but according to EverythingApplePro and leaker Max Weinbach, the mental health capabilities would not rely on such a feature.

"The panic attack detecting rumor was first shared by EverythingApplePro and leaker Max Weinbach back in April, who said that the Apple Watch will also be able to determine when a user is experiencing high levels of stress. Weinbach and EverythingApplePro did not suggest the feature would rely on blood oxygen monitoring, however, and said that it would be available on the Apple Watch Series 4 or later."

Blood oxygen monitoring can detect a respiratory or cardiac issue, so it will be another major health leap for the Apple Watch if the company pulls it off.

"Hints that blood oxygen tracking capabilities are coming to a future version of the Apple Watch were found in a leaked version of iOS 14. Blood oxygen monitoring is an important feature because a drop in blood oxygen levels can suggest a serious respiratory or cardiac problem that requires immediate medical attention."

We will have to wait until WWDC to see if Apple plans to bring its mental health features to the Apple Watch this year.

Apple Stores in the United States will start to reopen next week

The first Apple Stores in the US are reopening soon.

What you need to know

  • Apple Stores in the US will begin to reopen next week.
  • Idaho, South Carolina, Alabama, and Alaska will be first.
  • Temperature checks, social distancing, and face coverings will be required.

Apple's retail stores have been closed in the United States since March, but the company is about to begin reopening a small number of stores starting next week.

Reported by 9to5Mac, the first stores to reopen will be in Idaho, South Carolina, Alabama, and Alaska.

"Apple will focus its initial reopening efforts on regions less impacted by infection. The first Apple Stores in the U.S. to begin welcoming customers again are located in Idaho, South Carolina, Alabama, and Alaska. Apple operates six stores across the four states."

In order to ensure the safety of employees and customers, Apple Stores will have many new policies in place such as temperature checks, social distancing, and face coverings.

"We're excited to begin reopening stores in the US next week, starting with some stores in Idaho, South Carolina, Alabama and Alaska. Our team is constantly monitoring local health data and government guidance, and as soon as we can safely open our stores, we will.

We've missed our customers and look forward to offering our support. With many working and learning from home, our primary focus will be providing service and support at the Genius Bar. We'll open initially with additional safety procedures including temperature checks, social distancing, and face coverings to ensure customers and employees continue to stay healthy. Our new social distance protocol allows for a limited number of visitors in the store at one time so there may be a delay for walk-in customers. We recommend, where possible, customers buy online for contactless delivery or in-store pickup.

As local guidance varies around the US there may be slight modifications to our procedures. As always, our thoughts are with everyone affected by COVID-19 and those working around the clock to treat, study and contain its spread."

If you can get away with shopping online and do not need to visit a physical store, Apple has launched a new online hub to bring what you need most from the Apple Store to the company's website.
