SpaceX sent four tourists into space. The civilian crew will stay in orbit for three days

Published

SpaceX has launched four space tourists into space – this is the first mission for the company with exclusively civilians on board, among them there is not a single real astronaut. It was named Inspiration4.

The Falcon 9 rocket was launched yesterday from Launch Pad 39A at Kennedy Space Center, Florida at 8:02 pm local time. Approximately nine minutes after the launch, the first stage separated and returned to the barge in the Atlantic Ocean. A few minutes later, the second stage separated from the Crew Dragon. For the next hour and a half, the capsule gradually ascended into a given orbit due to periodic engine starts. Interestingly, this Crew Dragon is being reused: about a year ago, it delivered four astronauts to the ISS. But the Inspiration4 mission does not imply docking with the ISS – space tourists will spend three days in Earth orbit at an altitude of about 580 km.

Inside the spacecraft is billionaire entrepreneur Jared Isaacman, founder of payment processing company Shift4 Payments, Hayley Arceneaux, 29-year-old physician assistant, Christopher Sembroski, data engineer at Lockheed Martin, and Sian Proctor, a geologist and former NASA astronaut candidate.

The purpose of the mission on Earth is not entertainment at all: it raises funds for St. Jude’s Hospital, a nonprofit research center that provides free care for children with cancer. Isaacman donated $ 100 million to the hospital, and the plan is to raise about the same. Isaacman also paid for the rest of the crew’s seats. How much it cost him is not reported, but usually about $ 55 million is asked for one place.

The crew will have to entertain themselves on their own during the three-day stay in orbit. Sembrosky will reportedly play ukulele, and Proctor has brought along poetry of his own. At the same time, the entire team is participating in the study of the effects of microgravity on the human body: biological samples were taken from the crew before the mission, and they will also collect biomedical data while in space. This data will probably be needed later when sending people to the moon and Mars.

Facebook Papers Sheds Light on Social Media Moderation Issues

Published

on

The media, to which the company’s internal documents were leaked, claim that the company prioritizes profits over users.

The so-called Facebook Papers (an array of documents released to the public by former Facebook product director Francis Haugen) shed light on the problems with content moderation and the fight against disinformation on the platform. Major media outlets to which Haugen handed the documents, including Reuters, Bloomberg and The Washington Post, argue that the company prioritizes profit over user safety, although Facebook employees have repeatedly warned it of the potential risks.

For example, The Washington Post accuses Facebook head Mark Zuckerberg of downplaying the importance of reports that the site contributed to incitement to hatred, while addressing the US Congress. According to the newspaper, Zuckerberg knew that the problem was actually much more serious than it was reported to the public.

According to internal company documents, the platform removes less than 5% of hateful posts, and senior management (including Zuckerberg) was well aware of the platform dividing people into opposing camps. Facebook denies the allegations and claims its internal documents were misinterpreted.

Zuckerberg is also allegedly responsible for the decision not to suppress misinformation about COVID-19 in the early stages of the pandemic, as there could be a “significant trade-off with the influence of MSI” (meaningful social interaction – an internal Facebook metric). Facebook denies this, claiming that the documents have been misunderstood.

In turn, the news agency Reuters accused Facebook of regularly neglecting developing countries, which were allowed to publish publications inciting hatred and calling for extremist action. In other words, the company did not hire enough moderators with knowledge of the language and culture of these countries to effectively remove such content. Instead, it unjustifiably relied on its automatic moderation systems, which are ineffective in non-English-speaking countries. Again, Facebook denies these allegations.

According to reports from The New York Times, Facebook was well aware that the “Like” and “Share” functions (key elements of the social network) contributed to the spread of hate speech. As stated in a document titled “What Is Collateral Damage”, Facebook’s failure to address this issue will ultimately result in the company “actively (not necessarily knowingly) promoting such activity.” Again, Facebook claims the document was misinterpreted because the company would not harm its users.

Huawei Mate 50, similar to Huawei P50 Pro, shown in renders

According to rumors, Huawei has made serious progress in supplying components for its promising flagships of the Mate 50 line. Sources say that the most painful issue with single-chip systems has been resolved – Snapdragon 898 (albeit without a 5G modem) will be shipped by Qualcomm. In general, the future of the Mate 50 does not seem as vague as in the summer, but it is not yet clear what the smartphone will look like. One of the designers tried to offer his own vision of the Mate 50. And the person was inspired, apparently, the Huawei P50 Pro.

The Mate 50 shown in these renders is very similar to the P50 Pro, especially if we talk about the front panel with a screen extending to the side edges and a front camera embedded in the center.

If in the P50 Pro the main camera is shifted to the left, then in the Mate 50 it is located in the center. The modules are housed in two circular floors, all combined into one large circular chamber unit. Huawei has experimented with round camera blocks more than once, so such a solution may well be implemented in a production model. The designer, as you can see, depicted five modules, one of which is a periscope camera. The Huawei P50 Pro has one less module.

While there is no exact data on when the Huawei Mate 50 may debut. According to rumors, the premiere will take place closer to the summer (or early summer) of next year.
