Beyond Infinity: One year on Tianwen-1’s triumphant landing on Mars

Avatar

Published

May 15, 2022 marks the first anniversary of the remarkable touch-down by China’s Tianwen-1 on Mars in the southern part of Utopia Planitia, a vast plain on the northern hemisphere of the red planet, symbolizing the country’s first probe landing on a planet other than the Earth.

The name Tianwen, which literally means “ask the sky,” comes from Chinese ancient poet Qu Yuan’s masterpiece which reflects Chinese persistence in seeking truth and exploring the universe.

So far, Tianwen-1 has been exploring the surface of Mars for 356 Martian days and covered a total distance of 1,921 meters on the red planet. It has sent some of 940 gigabytes of precious scientific data back to the Earth, assisting the scientists in further revealing the mysteriously remote planet.

What is the Tianwen-1 Mars mission?

The Tianwen-1 Mars mission was approved in January 2016 by the China National Space Administration (CNSA), and the probe launched on July 23, 2020, carrying out deep-space maneuvers and expeditions on the red planet afterwards.

On February 10, 2020, Tianwen-1 successfully entered the orbit of Mars after a crucial braking system was activated to decelerate the spacecraft’s speed, enabling it to be captured by Mars’ gravity and become China’s first Mars satellite.

The primary mission of Tianwen-1 is to detect signs of life on Mars, be it in the present or the distant past.

In addition, the probe will also help examine the atmosphere, landscape, geological and magnetic characteristics on Mars to provide clues to the origin and evolution of Mars and the solar system. Based on all these, scientists might reveal if Mars could become a second home for humans.

China’s Mars rover finds evidence of water on Mars

Chinese scientists have found new evidence that there was water on Mars in the past and there are hydrated minerals on Mars, which can be potentially exploited during future crewed Mars missions

The findings from the data contribute to a growing body of telltale signs that suggests liquid water may have persisted much longer on Mars than previously thought, indicating that there are currently considerable stores of water in the form of hydrated minerals and possibly ground ice in this site.

The study published in the journal Science Advances on May 11 revealed that a large impact basin on Mars contained liquid water during the Amazonian epoch, the planet’s most recent geologic epoch.

Google trial wraps up as judge weighs landmark U.S. antitrust claims

FI

Published

By

Google and the U.S. Justice Department wrapped up closing arguments on Friday over claims that the Alphabet unit has unlawfully dominated web search and related advertising, in a case the government contends could shape the “future of the internet.”

U.S. District Judge Amit Mehta in Washington for hours grilled both sides with questions, probing whether competitive platforms such as ByteDance’s TikTok and Meta’s Facebook and Instagram are competitive substitutes for search advertising dollars.

Mehta said a central issue was platform “substitute-ability” for advertisers, which the court must resolve. He will now begin preparing to render a major decision on whether Google’s conduct broke civil antitrust law. He did not indicate when he would rule, but experts say he could potentially order changes to Google’s business practices.

Mehta also questioned whether Google assesses competitors’ pricing while considering its own adjustments. Google’s advertising business is responsible for about three-quarters of its revenue.

U.S. government lawyer David Dahlquist argued that “advertising revenue is what drives Google’s monopoly power today.”

Google has boasted it feels no real market pressures, Dahlquist said, arguing that the company does not fear increasing its pricing or not improving its products.

“Only a monopolist can make a product worse and still make more money,” Dahlquist argued.

Google’s lawyer John Schmidtlein countered that Google’s share of U.S. digital advertising revenue has steadily decreased. He touted the advertising power of rival platforms ByteDance’s TikTok, Meta’s Facebook and Instagram, and Amazon.

That’s because it’s not made from plastic, but wheat straw and has seeds nestled inside.

Schmidtlein argued that Google is “constrained” by rival platforms “where the eyeballs are,” because advertisers know there are overlapping audiences and can spend their dollars elsewhere.

He also asserted that Google was continually moving to innovate its search advertising products. “If Google is a monopolist, why improve anything? Why not just jack the price up?” he told the court. He later argued that “Google has won with a superior product.”

The Justice Department has hammered away at Google in a trial that started on September 12, contending the search engine giant is a monopolist that illegally abused its power to boost profits.

Witnesses from Verizon, Android maker Samsung Electronics and Google itself testified about the company’s annual payments, $26.3 billion in 2021, to ensure that its search is the default on smartphones and browsers, and to keep its dominant market share.

Mehta also took up the government’s claim that Google intentionally destroyed internal documents that were relevant to the issues in the lawsuit.

The government asked Mehta to presume that Google deleted chats that were unfavorable to the company.

Mehta repeatedly questioned Google’s prior policies, which he said left document retention decisions to its employees.

“They should have been preserved. Should there be some consequence for what at a minimum was far from best practices?” the judge asked.

A lawyer for Google, Colette Connor, defended its data preservation practices, calling them reasonable, and urged the court not to sanction the company.

The case, filed by former U.S. President Donald Trump’s administration, was the first of several aimed at reining in the market power of tech leaders.

Another case, against Facebook parent Meta, was also filed during the Trump administration. U.S. President Joe Biden’s antitrust enforcers have followed with a second case against Google and cases against Amazon.com and Apple Inc.

UN adopts first global artificial intelligence resolution to ensure AI is safe

The United Nations General Assembly unanimously adopted the first global resolution on artificial intelligence on Thursday, encouraging countries to safeguard human rights, protect personal data, and monitor AI for risks.

The nonbinding resolution, proposed by the United States and co-sponsored by China along with over 120 other nations, also advocates for the strengthening of privacy policies.

“Today, all 193 members of the United Nations General Assembly have spoken in one voice, and together, chosen to govern artificial intelligence rather than let it govern us,” U.S. Ambassador to the United Nations Linda Thomas-Greenfield said.

The resolution is the latest in a series of initiatives – few of which carry significant enforceability – by governments around the world to shape AI’s development amid fears it could disrupt democratic processes, turbocharge fraud, or lead to dramatic job losses, among other harms.

“The improper or malicious design, development, deployment and use of artificial intelligence systems … pose risks that could … undercut the protection, promotion and enjoyment of human rights and fundamental freedoms,” the measure states.

In November, the U.S., Britain and more than a dozen other countries unveiled the first detailed international agreement on how to keep artificial intelligence safe from rogue actors, pushing for companies to create AI systems that are “secure by design.”

Europe is ahead of the United States, with EU lawmakers adopting a provisional agreement this month to oversee the technology. The Biden administration has been pressing lawmakers for AI regulation, but a polarized U.S. Congress has made little headway. In the meantime, the White House sought to reduce AI risks to consumers, workers, and minorities while also bolstering national security with a new executive order in October.

The resolution aims to close the digital divide between rich developed countries and poorer developing countries to ensure that all are included in discussions on AI. It also aims to ensure that developing countries have the technology and capabilities to take advantage of AI’s benefits, including detecting diseases, predicting floods, helping farmers, and training the next generation of workers.

The resolution recognizes the rapid acceleration of AI development and use and stresses “the urgency of achieving global consensus on safe, secure and trustworthy artificial intelligence systems.”

It also acknowledges that “the governance of artificial intelligence systems is an evolving area” that requires further discussions on possible governance approaches and emphasizes that innovation and regulation are mutually reinforcing – not mutually exclusive.
