Perseverance landed

NASA's probe Perseverance survived the Mars atmosphere and successfully landed on the surface. The landing sequence was an engineering masterpiece. At first, the probe free-fallen through the Mars atmosphere. Then, deployed parachutes to decelerate. When the spacecraft was close to the surface, it fired onboard thrusters to slow itself down and hovered above the ground. Then the Perseverance was lowered down on cables to the surface.

Now, when the rover is on Mars, it can start its primary mission:

  • studying Mars' Habitability,
  • seeking Signs of Past Microbial Life,
  • collecting and Caching Samples,
  • preparing for Future Human Missions.

Also, during this mission, NASA will test a drone called Mars Helicopter. If it works, it will be the first time we will be flying (not just falling) on Mars.

CD Project Red hacked

CD Project Red has fallen victim to a ransomware attack. Hackers got access to the company's internal network and stolen some data. In the end, they encrypted everything. The hackers are threatening to release or sell the data if their demands are not met. If that happened, it would be a big blow to CDP Red. The stolen data contains source codes of the games (including the unreleased Witcher game), alongside internal legal, HR, and financial documents.CDP Red has confirmed the attack and stated that they will not negotiate or give in to the hacker's demands. Hearing that, Hackers haven't waited long and sold the stolen data on the Dark Web.

Earth's "invasion" of Mars begun

The two probes successfully reached Mars's orbit within 24 hours. The first one - Hope - is from the United Arab Emirates. The second one - Tianwen-1 - is from China. Both countries reached Red Planet for the first time. Now we are waiting for the Perseverance probe, which should reach its destination later this month.

Disney+ gains subscribers

A couple of weeks ago I reported that Netflix has 200M subscribers. I also mentioned fast-growing competitors like Disney+. This week Disney has confirmed my words, as Disney+ gained 95M subscribers in 14 months. This growth is unprecedented, even Disney thought they would achieve the 90M mark by 2024. If Disney keeps this momentum, it might become the most popular streaming service even this year.

Jeff Bezos steps down as CEO

Jeff Bezos announced that he is going to step down as Amazon CEO later this year. Andy Jassy, the CEO of Amazon Web Services (AWS), will replace Bezos as Amazon CEO. Bezos motivates his decision by wanting to focus on other projects like Blue Origin, and Bezos Earth Fund.

Another Starship test

SpaceX has launched the Starship rocket for the second time. Once again, it climbed to a target altitude of 10km. After that, the engines shut down, and the rocket started free-falling back to the ground. Unfortunately, like in the previous test, the rocket didn't quite stick the landing. It touched the ground when the rocket was still recovering from belly dive into a vertical position, which ended with a spectacular explosion.

It might seem like a failure, but SpaceX learned a lot. The same Situation was with Falcon 9 rocket - Space X failed many landing during tests, but now they are perfect.

Reddit vs Wall Street

This week Reddit users trolled the heck out of sharks of Wall Street. A hedge fund wanted to earn money by betting that Gamestop stocks would fall. Reddit users noticed that and started buying out the stocks. This caused the rise of stock value by over 1700%. As a result, the hedge fund bankrupted because it couldn't repay all the debts.

This is the first time something like this happened. This whole situation is being compared to French Revolution - "poor and small" people/investors turned against the rich people using their own tactics and tools against them.

Apple is doing just fine

Apple released financial reports for last quarter, and it looks like it  just broke its quarterly revenue record earning $111.4 Billion in Q1 2021. The revenue mostly comes from iPhones (42%) but iPad also gained a lot (in total 7%), and almost matched the Macs (8%).

SpaceX carpooling?

SpaceX launched Falcon 9 rocket with record breaking 143 satellites. This was done under the SmallSat Rideshare Program which is basically a space carpooling. Small businesses can share a flight with other companies instead of buying an entire rocket at a much higher price.

With such program, SpaceX has done just another step into affordable space exploration.

According to rumors, Apple decreased the production of iPhone 12 Mini in favour of  iPhone 12 Pro. The shift in production is a response to increased demand for iPhone 12 Pro.

Netflix surpassed the 200 million subscribers. Although those are impressive numbers, Netflix will have work hard to keep those users, as other services gain in popularity, especially Disney+.
