Watch live Monday: NASA Mars helicopter attempts 1st flight on Red Planet, ,
NASA’s Mars helicopter Ingenuity will attempt its first flight on the Red Planet on Monday (April 19) and you can watch the results come in live here, courtesy of NASA.
Ingenuity is expected to take flight on Mars at 3:30 a.m. EDT (0730 GMT), but it will take nearly three more hours before NASA receives data from the test flight. The space agency will livestream that data’s arrival at 6:15 a.m. EDT (1015 GMT), which you can watch here.
The $85 million Ingenuity helicopter will be the first powered flight on another world and the first-ever aircraft on Mars. It is expected to make a very short first flight to reach a height of 10 feet and then land.

The original flight date of April 11 shifted as engineers worked on preflight checks and a solution to a command sequence issue. The Perseverance rover will provide support during flight operations, taking images, collecting environmental data, and hosting the base station that enables the helicopter to communicate with mission controllers on Earth.
This technology demonstration is supported by NASA’s Science, Aeronautics Research, and Space Technology mission directorates. JPL, managed for NASA by Caltech in Pasadena, California, built and manages operations for Ingenuity and the Mars 2020 Perseverance rover.

Twitter, Facebook, and Snap are reportedly part of White House vaccination campaign, Kim Lyons
Illustration by Alex Castro / The VergeFacebook, Twitter, and Snap are among the companies that will assist with the Biden administration’s promotional campaign for vaccine eligibility, Axios reported. The White House had set a date of May 1st for states to open coronavirus vaccine eligibility to all adults, but later pushed it to April 19th.
The White House is hoping to reach populations who may have higher rates of vaccine hesitancy with the effort. Anthony Fauci, the president’s chief medical adviser, will do video clips on Snapchat, according to Axios, and Facebook and Twitter will send out push alerts to notify users that they’re eligible to receive the vaccine. Vice President Kamala Harris will also be involved with the social media push.

Vice President Kamala Harris will also be involved with the social media push.
Half of all US adults have received at least one COVID-19 vaccination, according to the Centers for Disease Control and Prevention (CDC), But the administration appears concerned that last week’s decision to pause the use of the Johnson & Johnson vaccine may have made people already hesitant to receive a vaccine even more wary.
The Food and Drug Administration (FDA) and CDC recommended last week that the US pause the use of the Johnson & Johnson vaccine after six people who received the shot experienced unusual blood clots. The agencies wanted time to investigate whether there’s a connection between the clots and the vaccine. Fauci said on Sunday that he believes the pause will be lifted by Friday, perhaps under some kind of restriction or warning.
“We can confirm that Snap has been in touch with the White House regarding efforts to spread awareness of vaccine eligibility among Snapchatters,” a spokesperson said in an email to The Verge, “building on our continued efforts to support our community during the COVID-19 pandemic.” The spokesperson did not elaborate on details of the efforts.
Likewise, a Twitter spokesperson confirmed in an email to The Verge that the company was “working in partnership with the White House to elevate authoritative information in regard to COVID-19,” but did not share further details.
Facebook and the White House did not reply to requests for comment on Sunday.

Roblox to introduce content ratings for games to better restrict age-inappropriate content, Kim Lyons
Photo Illustration by Rafael Henrique/SOPA Images/LightRocket via Getty ImagesVirtual gaming platform Roblox is developing content ratings for games and easier-to-use parental controls, the company’s chief privacy officer Remy Malan told The Wall Street Journal.
Half of Roblox’s audience of more than 30 million daily users are kids under 13, but the platform has struggled at times to contain sexually explicit content. Age-inappropriate games sometimes surface up on kids’ “recommended for you” lists, according to the WSJ.
The platform’s current system restricts kids to specific games, but under the new system, parents would have more information about what kids might find in a given game; until you play a game, it’s not always clear that it might have explicit or inappropriate content in it.

Virtual gaming platform Roblox is developing content ratings for games and easier-to-use parental controls, the company’s chief privacy officer Remy Malan told The Wall Street Journal.

The platform’s current system restricts kids to specific games, but under the new system, parents would have more information about what kids might find in a given game; until you play a game, it’s not always clear that it might have explicit or inappropriate content in it.
Malan did not indicate when the new ratings system would be available, but said Roblox has a team of more than 2,300 people monitoring games for safety, and uses a mix of human moderators and AI.
Roblox, which launched in 2006, has been a runaway hit during the pandemic, giving socially-distanced kids a social space to gather online. The company reported revenue of $588.7 million during the first nine months of 2020, a 68 percent increase over the same period in 2019. Roblox went public via direct listing in March, and said in its prospectus that its users spent an average of 2.6 hours daily on the platform over the past year.

Google introducing a feature in Chrome 90 to create links to highlighted text on a webpage, Kim Lyons
Illustration by Alex Castro / The VergeAn upcoming feature in Chrome 90 will allow users to create a link to a section of a website that they’ve highlighted. First launched as a browser extension called Link to Text Fragment last year, Google has now added the feature within Chrome itself.
The new feature is still rolling out to users; I wasn’t able to get it to work even after I updated to Chrome 90.

An example of what the end result looked like using the browser extension can be found here (but only in Chrome and Edge browsers).
Google said the “copy link to highlight” feature is already available on desktop and Android devices for some users. The feature is “coming soon” to iOS, the company added.
