The White House will meet with executives from major tech companies, including Alphabet-owned Google (GOOGL.O), Apple Inc (AAPL.O) and Amazon.com Inc, , to discuss software security after the United States have suffered several major cyber attacks last year.

 In December, White House National Security Advisor Jake Sullivan sent a letter to CEOs of tech companies after  a security vulnerability was discovered in open source software called Log4j that organizations around the world are using. to save data in their applications. 

In the letter, Sullivan noted that this open source software is widely used and maintained by volunteers and is a "major national security problem." 

Thursday's meeting, which will be hosted by the Deputy National Security Advisor for Information Technology and Emerging Technologies. discuss concerns about the security of open source software and how it can be improved, the White House said in a statement.

Other top tech companies in attendance at the meeting will include IBM (IBM.N), Microsoft Corp (MSFT.O), Meta Platforms Inc (FB.O) which owns Facebook and Oracle Corp (ORCL.N). Government agencies, including the Department of Homeland Security, Department of Defense and the Commerce Department, will also be in attendance.

Cybersecurity has been a top priority for the Biden administration after several major cyberattacks last year, which exposed thousands of records held by companies and government agencies to hackers.

One hack, which the U.S. government has said was likely orchestrated by Russia, breached software made by SolarWinds (SWI.N) and gave hackers access to thousands of companies and government offices that used its products. The hackers got access to emails at the U.S. Treasury, Justice and Commerce departments, and other agencies.

Remember That Weird 'Cube' on The Moon? Yutu-2 Finally Took Closer Pictures

The mysterious Chinese “moon cube” is no longer a mystery. The big reveal: it's a rock that doesn't even have the shape of a cube. National rover Yutu2  discovered the object - which appeared to be a gray cube looming above the lunar horizon - in early December. China's National Space Administration (CNSA) dubbed it the “mystery hut,” playfully speculating that the cube could be an alien house or a spaceship.
 The news called it the "moon cube".

 The CNSA estimated that the object was about 80 meters (262 feet) away, according to the blog  affiliated with the agency, and ready to point the rover towards it. The blog said it would take two or three months to reach the cube.
 After several weeks of preparation and driving, the rover is close enough to see that the "mystery hut" is just a rock. Its sharp geometric aspect on the horizon was a simple turn of perspective, light and shadow.

In an updated posted on Friday, Our Space published the rover's latest photo of its target, below.

One of the rover's ground controllers noted on the blog that the rock is shaped like a rabbit, with smaller rocks in front  that resemble a carrot. The rover's name, Yutu, means "jade rabbit," which is now also the name of the rock too.

Yutu2 reached the moon in January 2019, when the Chang'e4 lander landed on the lunar surface and launched a ramp for the rover's descent. It was the first mission to land on the opposite side of the moon. 

Over the next three years, Yutu2 traveled over 1,000 meters (3,200 feet), used ground-penetrating radar to reveal a surprisingly deep layer of lunar soil, and identified rocks in the lunar mantle, below the crust, which have been pushed to the surface. when an asteroid crashed into the moon billions of years ago.

The rover has survived long past its initial three-month mission, meaning Yutu-2 had plenty free time for a wild cube chase.

NASA completes James Webb final deployment

 NASA's James Webb Space Telescope team has fully deployed its 21-foot gold-plated primary mirror, completing the final phase of all major spacecraft deployments in preparation for scientific operations. 

As a joint effort with the European Space Agency (ESA) and the Canadian Space Agency, the Webb mission will explore every phase of cosmic history, from  the solar system to the most distant observable galaxies in the early universe.

NASA Administrator Bill Nelson commented on the development: “Today NASA has achieved another engineering milestone that has lasted for decades. While the journey is not over, I am joining the Webb team to breathe a little easier and envision future advances that are determined. ”To inspire the world. The James Webb Space Telescope is an unprecedented mission that is about to see the light of the first galaxies and unravel the mysteries of our universe. Every achievement and every achievement in the future  is  testament to the thousands of innovators who put their  passion for life into this mission. 

The two wings of Webb's primary mirror were bent prior to launch to fit into the nose cone of an Arianespace Ariane 5 rocket. After more than a week of other critical spacecraft missions, Webb's team began remotely deploying the hexagonal segments of the main mirror, the largest ever launched on launch. Place.

The telescope will now begin moving its 18 primary mirror segments to align the telescope optics. The ground team will command 126 actuators on the backsides of the segments to flex each mirror – an alignment that will take months to complete. Then the team will calibrate the science instruments prior to delivering Webb’s first images this summer.

Thomas Zurbuchen, Associate Administrator for Science Mission Directorate in NASA Headquarters in Washington, added: “I am so proud of the team – spanning continents and decades – that delivered this first-of-its-kind achievement. Webb’s successful deployment exemplifies the best of what NASA has to offer: the willingness to attempt bold and challenging things in the name of discoveries still unknown.”

Webb will also shortly undergo a third midway correction burn - one of three designed to bring the telescope into precise orbit around the second Lagrangian point, commonly known as L2, nearly 1 million miles from Earth. This is Webb's last orbital position where his sunshade protects him from light from the sun, earth, and moon that could interfere with  infrared light observations. Webb was designed to look back over 13.5 billion years to capture infrared light from celestial objects in much higher resolution than ever before and to study our own solar system as well as distant worlds. 

Gregory L. Robinson, Director of the Webb Program at NASA Headquarters, said, “The successful completion of all  Webb space telescope missions is historic. This is the first time a NASA-led mission attempts to complete a complex sequence of observatory in space, a remarkable feat for our team, NASA, and the world.

Chinese police rap Walmart for cybersecurity loopholes - local media

Chinese authorities rapped Walmart for allegedly breaking cybersecurity laws, according to local media, the latest issue for retailer U.S which is already the subject of allegations in the country for allegedly halting sales of products from the Xinjiang.

Police in southern China's Shenzhen city discovered 19 "vulnerabilities" in Walmart's network system (WMT.N) in late November and accused them of taking a long time to fix the flaws the China Quality News, backed by the country's market regulator, reported on Wednesday.
Walmart was ordered to make fixes, the report said, without mentioning fines or details of the vulnerabilities.
The retail giant and the Shenzhen police did not immediately respond to requests for comment on Friday.

This marks a fresh set of troubles in China for Walmart, which in the past month has faced criticism for what local media has said was its deliberate removal of products sourced from Xinjiang from its apps and stores.


Xinjiang is a growing point of conflict between the Western governments and China, as U.N. experts and rights groups estimate more than a million people, mainly Uyghurs and members of other Muslim minorities, have been detained in camps there.


China has rejected accusations of forced labour or any other abuses in the far western region.
Walmart has seen a wave of  membership cancellations of its  arm Sam's Club branch in China since the Xinjiang problem.
The Chinese transplant agency also accused the retailer and the Sam's Club of "stupidity and myopia".

Although Walmart has not commented publicly  on the matter, Reuters reported that a Sam's Club executive told analysts during a phone call that it was a "misunderstanding" and that there had been no deliberate withdrawal of products from Xinjiang fined 10,000 yuan ($ 1,568) in Shanghai by the city's market regulator for violating food safety laws after discovering that a frozen plant product did not have a production date or of expiration date, according to a separate report released by local media.


SpaceX’s Starlink internet service has more than 145,000 users so far

Elon Musk's SpaceX provided an update on its Starlink internet service on Thursday, as the company launched more satellites into orbit. 

SpaceX engineer Jessie Anderson said during a webcast of the company's first launch of the year that Starlink now has more than 145,000 users in 25 countries around the world. It fell from 140,000 users in early November, but represents a slowdown in user growth. 

On Thursday, the company launched a Falcon 9 rocket from Florida, carrying 49 Starlink satellites into orbit. 

Starlink is the company's plan to build an interconnected Internet network with thousands of satellites - known in the space industry as a constellation. 

It is designed to provide high speed Internet access to consumers all over the planet. SpaceX has approximately 1,800 Starlink satellites in orbit.

The increase of 5,000 users in two months represents slower growth. As of November, SpaceX had added about 11,000 users per month since the service began in October 2020.

 Late last year, SpaceX noted on its website that the "silicon shortage has delayed production" of Starlink user terminals, “which  impacted our ability to fulfill orders. 

SpaceX's valuation has reached over $100 billion, which industry analysts attribute largely to the market potential of its Starlink service.

Pluto should be reclassified as a planet, Scientists reclaimed

You know the old motto: Nobody can hear you screaming in space. Unfortunately, being trapped in our rapidly heated rock, we can hear everyone screaming very well, especially those ironically howling about the specifics of space.

Checked in at our degraded friend Pluto, it was  certainly not a planet, despite a decade and a half of complaints from overly engaged astronomy fans (Welcome to the world of pop culture, astronomy fans).

 His appointment lately has primarily sought to compensate everyone, the fact of the matter is that  the International Astronomical Union is still very unlikely to step back on its 2006 decision apparently they raised their hands and gave their goforbroke request from "To hell.

 We not only want Pluto to come back, we want  150 more damn planets to be added to the list."


That's the gist of a new article published in the research journal Icarus that argues that the IAUs are the real Jabronis here, dammit. 

As NBC News breaks it down, the team of scientists claims that the current planetary classification system relies more on outdated astrological methods. (read: pseudoscientific) terminology and should be updated to reflect modernity. A "planet" is by definition "any geologically active body" in space that would not only bring Pluto  into its lap, but also moons such as Europa, Enceladus and Titan, as well as the asteroid Ceres.

A total of around 150 new "planets" will be added to the eight existing ones. Unfortunately, as planetary geologist Paul Byrne explained, all of this backlash to taxonomy often overshadows many of the other really fascinating aspects of these celestial bodies of all sizes. 

"Every time I gave a talk and  put up a picture of Pluto, the first question wasn't about the geology of the planet, but why was it degraded?" he told NBC News. "It stuck with people, and that's a real shame.

Elon Musk says SpaceX will land humans on Mars in 10 years in the worst-case scenario

 

Space X

Elon Musk said that in the worst case scenario, SpaceX would bring humans to Mars in 10 years.

 Spaceship engineering and cost reduction are the determining factors. "No amount of money can get  a ticket to Mars,"  added in  Lex Fridman. 

Elon Musk said that SpaceX will bring people to Mars in 10 years with its Starship rocket, in the worst case break, the billionaire replied: “The best case is about five years, the worst case 10 years.

 Musk told Fridman that the determining factors included  the design of the vehicle, adding that “Starship is the most complex and advanced rocket  ever built. 

"The basic optimization of Starship is to minimize the cost per ton for orbit and ultimately the cost per ton for the Martian surface," Musk told Fridman on the podcast. Millions of dollars, Musk told Fridman.

 "No amount of money can get  a ticket to Mars," he said on the podcast.The SpaceX and Tesla CEO has predicted multiple dates for his company's arrival and landing on the Red Planet.

 Musk said in an interview with the Clubhouse audio app  in February that it will be "five and a half years" before a manned SpaceX spacecraft mission takes place. 

Missile could land on the red planet. Musk tweeted in March that his aerospace company would land its Starship missiles "long before" 2030 on Mars.

SpaceX will be landing Starships on Mars well before 2030. The really hard threshold is making Mars Base Alpha self-sustaining.

— Elon Musk (@elonmusk) March 23, 2021


Experts say it could take longer than they predict if things don't go exactly according to plan during the three remaining launch opportunities before 2026.

 Musk is finally planning to build 1,000 Starship missiles, launching three of them a day, to bring a million people to the Red Planet.

Elon Musk criticised on Chinese social media over risk of 'collision' between Starlink satellites and space station

 


Elon Musk been criticized on social media after China complains that its space station was forced to avoid collisions with satellites launched by its Starlink Internet Services project.

China submitted a document earlier this month to the UN's space agency saying that satellites from the Starlink division of Mr Musk's SpaceX  company had two "close encounters" with the Chinese space station on 1 July and 21 October

The incidents behind the complaints filed with the UN space agency have yet to be independently verified.

Starlink is a satellite Internet network owned by Elon Musk SpaceX.

Elon Musk is known in China, even though his Tesla electric car manufacturer has a growing review of regulatory authorities.


Starlink and the US have been heavily criticized on China's Weibo microblogging platform Twitter.

As news of the filing spread, users of the Chinese microblogging platform Weibo piled on, with one user saying Starlink satellites were "just a heap of space junk" and another describing them as "American space warfare weapons".

"The risks of Starlink are being gradually exposed, the whole human race will pay for their business activities."

China also accused the United States to bring astronauts in danger by ignoring obligations under the spaces' contracts.

The spokesman of the Foreign Ministry, Lijian, said that China requested the United States to act responsibly.

Scientists have voiced worries about the dangers of collisions in space and referred to as on global governments to percentage statistics about the predicted 30,000 satellites and different area particles which can be orbiting Earth.

SpaceX has already launched nearly 1,900 satellites as a part of the Starlink network, and plans to install thousands more.

Last month, the US space agency Nasa abruptly postponed a space walk from the International Space Station due to concerns about space debris.
