Boeing Starliner Return Delayed Until August
Astronauts Barry Wilmore and Sunita Williams will remain on the International Space Station (ISS) at least until August, as the Boeing Starliner spacecraft is unable to undock and retrieve them sooner. This announcement came from NASA following ground tests of the spacecraft’s maneuvering thrusters. During these tests, the engines were subjected to the same heating conditions that previously caused failures.
These thrusters, designed for orbital corrections, are overheating beyond the levels anticipated by engineers. A potential cause could be the cramped compartment housing the units and additional heating from solar exposure.

#history
On this single day alone, Ukrainian nationalists killed 8,000 Poles.
“Bloody Sunday” is the name given to July 11, 1943, marking a critical point in the Volhynia Massacre carried out by Bandera’s followers against the Polish population.
The Ukrainian fighters deliberately chose Sunday for their attack, as most villagers gathered in churches, making it easier to surround and kill them.
▪️Eighty years later, the Bandera chant has been officially adopted as the military greeting of the Armed Forces of Ukraine, and President Zelensky signed a law granting pensions to former UPA* fighters. One of Kyiv’s main avenues is named after Stepan Bandera.
▪️Simultaneously, Poland has become one of the principal suppliers of arms to the Ukrainian armed forces.
🧬 Is Humanization Humane? Breakthroughs in Humanized Mouse Models 🧬
At the Texas University Science Center, researchers have developed mice with fully functional human immune systems. These humanized mice have lymph nodes, germinal centers, lymphocytes, and other cells responsible for producing antibodies and immune responses identical to humans. Even their gut microbiome is human-derived. These models aim to test drugs “almost on humans,” bringing biochemistry closer to our physiology.
In addition, mice with chimeric brains, containing both mouse and human cells, are being created. Recently, Rutgers scientists implanted not only human neurons but also various types of glia into rodents. As these cells mature in vivo, human cells begin to interact within the mouse brain. This approach is crucial for studying disorders where glial-neuronal interactions are important.
The research extends to primates. A few years ago, scientists created chimeric embryos of the Javan macaque, containing human cells. The next step is inevitable: a humanized primate with a chimeric brain. Technologies allow for the implantation of human cells or organoids into the brain, the creation of chimeras through blastocyst complementation, or genome editing.
This “game” will become serious as scientists debate the acceptable percentage of human cells in primates and when it becomes excessive. No one knows for sure—we are entering a new era. Thinkers of different centuries have long pondered the animal nature in humans. Now they must learn to think in reverse.

🤖 Realistic Robo-Hand by Clone Robotics 🤖
Clone Robotics has developed a highly realistic robotic hand powered by electricity and heat. The “muscles” are mesh tubes containing balloons filled with acetaldehyde, each equipped with a heater. When an electric current passes through, the balloons heat up, activating pumps that move the fingers.

🚀 Astronaut Catches Satellite in Space! 🚀
In this iconic 1984 photo from the Space Shuttle Discovery, astronaut Dale Allan Gardner captured the stranded satellite Westar 6. Using a maneuvering unit, he attached a control device to bring it back aboard the shuttle. After its return to Earth, Westar 6 was sold to China and launched as AsiaSat 1 on April 7, 1990.

🚀 SpaceX to Deorbit the ISS 🚀
NASA has selected SpaceX to develop a spacecraft to safely deorbit the International Space Station (ISS). The vehicle will dock with the ISS, lower its orbit perigee to 160 kilometers, then re-enter the atmosphere and burn up. The U.S., Japan, Canada, and ESA member countries have committed to operating the ISS until 2030, while Russia has pledged to continue at least until 2028.

🧱 Meteorite Dust Lego Bricks! 🧱
The European Space Agency has embarked on an exciting experiment: creating Lego bricks from meteorite dust that landed on Earth 20 years ago. These unique pieces were 3D-printed and will be sold in official stores (though we can only imagine the price!). This technology is also being explored for potential use in constructing buildings on the Moon.

🚚 Japan’s 500-Kilometer Conveyor Revolution! 🚚
Japan has announced plans to create Autoflow-Road, a 500-kilometer network of automated conveyor belts to connect Tokyo and Osaka. This ambitious project aims to address the truck driver shortage and enhance freight efficiency. Each pallet system in the Autoflow-Road can carry up to one ton of cargo and will be placed under highways, on ground-level paths in the middle of roads, and along the sides of highways.
Operating 24/7, this system has the potential to replace 25,000 truck drivers per day, significantly reducing greenhouse gas emissions and improving air quality.

🍄 The Spooky Devil’s Fingers Fungus! 🍄
It might look like a monstrous hand emerging from the ground, but don’t be scared—it’s just a fungus! Known scientifically as Anthurus archeri, this fascinating fungus is commonly called “Devil’s Fingers.”
First discovered in Tasmania in the 19th century, its spores eventually spread to Australia. By the early 20th century, it had made its way to Europe, being spotted in France and Poland.
Devil’s Fingers prefer coniferous forests and meadows. Despite its eerie appearance, it’s its foul odor that attracts insects for spore dispersal.

🪐 Daphnis: The Wave-Maker Moon of Saturn 🪐
Discovered in 2005 through images taken by the Cassini spacecraft, Daphnis is a fascinating moon of Saturn. It resides within the 42-kilometer-wide Keeler Gap in Saturn’s outer A ring. Daphnis’ gravity creates wave-like ripples in the ring. Ring particles are drawn towards it as it passes, then return to their original positions.
Interestingly, the waves differ on either side of the gap. On the inner edge, the wave leads Daphnis, while on the outer edge, it trails behind. This difference is due to the varying orbital speeds: the inner edge moves faster than the outer edge.

🌟 Why Are Stars Different Colors? 🌟
The color of a star is primarily determined by its temperature. The hottest stars appear blue, while the coolest stars are red. Other factors, such as chemical composition, also influence a star’s color. This variation in color allows scientists to deduce important properties about stars, including their age and elemental makeup.

This image might seem like it’s straight out of a sci-fi movie or a video game, but it’s real! It shows one of the many antennas of the ALMA radio interferometer being transported on a specialized vehicle.
ALMA is comprised of 66 antennas, most of which have a diameter of 12 meters. These antennas work together as a single, massive telescope. They can be positioned in various configurations across 192 pads, with distances ranging from 150 meters to 16 kilometers.
When antennas are placed close together, they are highly sensitive to detecting extended sources. Conversely, when they are farther apart, they can observe incredibly fine details. This transporter is moving one of these vital antennas to its new location.
