Hello!
Attempt number 2 - the weather on the launch pad is good, which means Crew Dragon has every chance to take off in 45 minutes.

The launch was successful! We are waiting for the broadcast of the docking with the ISS tomorrow evening

Hello! Today, NASA on the Atlas V 541 rocket sent another rover to Mars - Perseverance (Perseverance). The rocket was launched from the SLC-41 launch pad at Cape Canaveral. To help the Perseverance rover search for traces of ancient life on Mars will be an unmanned helicopter Ingeniti (Ingenuity, "Ingenuity"). The helicopter-drone is the first attempt to make "controlled flight" in the atmosphere of another planet, except for the landing of rockets. Launching a helicopter in a rarefied atmosphere draws additional attention to the rover's satellite. Official NASA stream with the launch still on the air: https://youtu.be/21X5lGlDOfg

Hello! Anatomy - an established science where you should not expect discoveries? But no - it turns out that new organs in the human body are opened with enviable regularity.

The article on Medusa, in the "history" section, introduces the discoveries of the anatomy of the 21st century - an unknown salivary gland, the lymphatic system in the brain, and even a ligament in the knee "lost" since 1879.

I advise you to read: https://meduza.io/feature/2020/11/01/novosti-anatomii-uzhe-ne-oksyumoron

Hello! A detailed story about the closure of Arecibo was published on Habré. One of the largest, and perhaps the most famous radio telescope in the world, is permanently disabled and will be dismantled:

Hello! The previous news failed to become a reality.

The Arecibo radio telescope was not closed - it collapsed. A massive 900-ton mobile platform with irradiators, suspended on cables, collapsed on a spherical reflector with a diameter of 305 meters, located in a karst funnel.

The collapse of the platform also destroyed the tops of the three support towers surrounding Arecibo, to which were connected the cables holding the platform in the air.

The process of destruction on video: https://youtu.be/ssHkMWcGat4

Hello! In the photo - "nuggets" from chicken meat, during the production of which not a single chicken was harmed. Singapore Food Agency approved the sale of chicken meat by the American company Eat Just - to produce artificial meat, the company's specialists took chicken cells by biopsy and then cultivated them in bioreactors, combining them with a proprietary mixture of proteins, amino acids, minerals, sugars, salts and other nutrients. substances.

The original cells come from chicken muscle cells, and the nutrients added to the reactor come from plants. Now the volume of the "bioreactor" is 1,200 liters, and in order to provide all of Singapore with artificial meat and bring it to markets, the volume of reactors needs to be increased to 10 or 50 thousand liters.

How much such meat costs? Amount definitely cannot be compared with another analog - artificial meat for a burger, in favor of "chicken". The base cost of whey-free "meat" growing medium and its vegetable analogs is about three dollars per liter.

P.S. If this focus on chicken replacement doesn't sound like a major hitch to you, just remember that according to the World Economic Forum, 50 billion chickens are killed around the world every year for meat, averaging 130 million chickens per day.

Singapore became the first country to approve the sale of artificial meat.

Hello! It's nice when the news about the launch can be supplemented with information about a successful landing.

Landing on Mars in the area of the Lake crater will allow to study the ancient environment on the planet's surface, geological processes and history, search for evidence of life within the available geological materials, as well as collect samples of Martian soil for their subsequent delivery to Earth as part of the Mars Sample Return mission

First uploaded photo looks a bit like snow, but of course it's not ❄️

Hello! Better than the Mars landing video can only be improved by neural networks up to 4K, 60fps and with added sound video: https://youtu.be/2_KY69w0LQw

Hello! The Ingenuity Marshall will make its first flight on April 19 at approximately 11:30 a.m. Kyiv time.

The data he collected will arrive on Earth a few hours after the flight - before meeting at the NASA broadcast, which will begin at 13:15 Kyiv time: https://youtu.be/p1KolyCqICI

Arnold Schwarzenegger has already left his wishes for a successful flight: https://twitter.com/Schwarzenegger/status/1383876808295129093

"Ingenuity", also known as Mars Helicopter, according to the plan will rise by 5 meters, fly about 300 meters in 90 seconds (the battery will not be enough for more).

Hello! And here is the video of the first flight of the Ingenuity drone on Mars, filmed by the color camera of the Perseverance rover:

"Marsolet" will work on Mars for 30 sols (Martian days) and will carry out four more flights. We wait!

Hello! China's Zhurong rover... Under development? Launched? Tested? Unlike NASA projects, too little attention has been paid to it.

So, he successfully reached Mars, and will spend the next 90 sols (Martian days) exploring the surface. Zhurong (in translation, the god of Fire, which occupies not the last place in the mythology of China) has landed on the plain of Utopia, and will search for ice.

As with other rovers, the nominal operating life can be exceeded by several times.

Hello! And this photo is the most "detailed" photo of atoms that exists at the moment. PrScO3, two electron microscopes. The blur in the photo is the effect of electrons. More details: https://news.cornell.edu/stories/2021/05/cornell-researchers-see-atoms-record-resolution
