Who's the most garbage in space? Analysts presented a ranking of countries

Humanity has already turned the Earth into a huge garbage dump, and is now trying to do so with orbit as well. The next step will probably be the Moon and Mars. However, we can limit our devastation of outer space by creating projects to clean it. Many companies are already successfully testing their technologies, but dealing with so much rubbish will not be an easy task.

Falcon-9 and Crew Dragon by SpaceX have received official NASA certification. We are waiting for the start

It is certain that NASA has officially certified SpaceX and it is the first such case in nearly 40 years, in which a Space Shuttle performed routine flights to the ISS - thanks to this, the Crew-1 mission will start its flight to the International Space Station in a few days. NASA worked with a company founded by Elon Musk as part of the Commercial Crew Program, whose motivation is, of course, the independence of the American space agency from Russian solutions. Thanks to the Falcon 9 rocket and the Crew Dragon capsule, it will finally be possible, and moreover, the Americans will return to space flights from their own territory.

Meet Jamoc, the new robo-dog from Tencent, the Chinese gaming giant

Jamoca is the newest and most advanced robo-dog in the company's history. Engineers from the secret Robotics X Lab department have been working on the project for some time. This is where robots are designed and built, which will soon appear on the streets of Chinese cities, where they will take care of their safety, inform residents about important matters or deliver parcels from stores.

Pentagon is testing electromagnetic weapons. The missiles fly at a speed of 9,200 km / h

The Pentagon has been intensively developing railgun technology for several years. For the purposes of testing, weapons are prepared by defense companies: General Atomic and BAE Systems. The American electromagnetic weapon consists of a 155-millimeter cannon that fires 10 rounds per minute with an energy of 32 megajoules and a speed of 9,200 km / h without any problems. Ultimately, the devices are to be capable of hitting targets up to 200 kilometers away at speeds of up to 6,000 km / h.

The Chinese Jiuzhang quantum computer has made groundbreaking calculations

Recently, Google announced to the world that the quantum computer it is building, called Sycamore, only needs a few minutes to make calculations that would take a classic computer about 10,000 years. Now we are hearing news that the newest and one of the most advanced quantum computers in the world from China has broken this record.

Watch the spectacular explosion of the Starship prototype during landing

The prototype with the designation SN8 took off in a beautiful manner, soared to a height of 12 kilometers and without any problems started a very interesting-looking landing maneuver, but in the last seconds it flew too fast and hit the plate of the company's test center in Boca Chica, Texas with all its force. Elon Musk tweeted that there was a problem with the pressure of the top tank, as a result of which the Raptor engines power dropped and they were unable to brake the vehicle just in front of the center plate. The billionaire also said they had sensor data, so they'll fix this problem quickly.

Antibiotics are produced that slow down the growth of antibiotic-resistant bacteria

In short, the overuse and inept use of antibiotics (for example, to "treat" viral infections or prematurely discontinue therapy) have made more and more bacteria resistant to them, making it difficult to treat many diseases. And while we are still developing new antibiotics, the process is not fast enough to keep up with the bacteria - luckily, there is a light in the tunnel, and we are talking about antibiotics to be used together and antibiotics to reduce the development of bacterial resistance. This is a perfect example of how evolution works, because when a drug wipes out a bacterial population, a few out of several million will survive, often due to random genetic mutations, and will pass on new immunity to the next generation.
