NASA’s Perseverance rover is about to start searching for life on Mars   What’s happening: NASA is going to land its Perseverance on Mars today—and begin the search for life on the planet.  The rover will enter the Martian atmosphere and attempt to make it to the planet’s surface safely from 2.15pm ET today (you can watch along live). NASA officials have an expression for what it’s like to land a rover on Mars: seven minutes of terror. A million things could go wrong.  How it’ll go down: Those seven minutes start when the spacecraft enters the Martian upper atmosphere at around 20,000 kilometers per hour (12,500 miles per hour). It will face temperatures of 1,300 °C (2,400 °F). About four minutes in, the rover will deploy a 21-meter parachute. It sheds its heat shield. At a little less than six minutes into EDL and around two kilometers in the air, the outer shell and parachute separate from the rover, and Perseverance heads directly for the ground. It uses its thrusters to find a safe spot, and slows down to around 2.7 km/h (1.7 mph) before landing. After about ten days, it should deploy a mini-helicopter called Ingenuity. What it’s there for: Should it succeed, Perseverance will explore Jezero crater, a former Martian lake bed and look for fossilized remains of ancient life. We may know if there’s any there really soon. Read the full story. —Neel V. Patel Australia has become the battleground for a power struggle between governments and Big Tech The news: Australians woke up on Thursday to Facebook timelines devoid of any news. Faced with the option of either paying to link back to publishers to comply with an incoming Australian law, or entirely pulling the plug on hosting news, it chose the latter. As it stands, Facebook users in Australia can't use the platform to see or share content from any news outlets anywhere in the world, and no one can post links to Australian publishers, wherever they are. Users say government websites like fire services and meteorology departments have been caught up in the ban too, most likely due to issues with the machine learning system Facebook uses to enforce it. Users and officials in Australia reacted furiously, with the country's prime minister describing Facebook's actions "as arrogant as they were disappointing" and insisting "we will not be intimidated by Big Tech."  Why? Lawmakers in Australia are in the final stages of passing a proposed new Media Bargaining law. In essence, the law would require the tech platforms would have to pay publishers to host their content. If they couldn’t agree a price, Australia would create an arbitration panel which would set one. Google has taken the opposite approach to Facebook, and has cut numerous deals with publishers in Australia, including News Corp, to ensure it can comply with the law if it passes, and continue linking to their services.  What's next: Australia has essentially become the latest battleground for the years-long fight between governments, publishers, and Big Tech. Facebook's move is a big, ugly power flex, but Australia's law seems pretty crude and unattractive too. It doesn't require publishers to plough any of the money they receive into journalists' salaries or original reporting, and could help to further entrench Australia's already highly concentrated media market. In short, the current situation is unsustainable and undesirable for everyone. Australia’s Treasurer Josh Frydenberg is in talks with Facebook's CEO Mark Zuckerberg, and the pressure is on for them to come up with a better solution.
