Scientific Bulletin titles: – The success of the deliberate collision of the Dart spacecraft with the asteroid Demorphos in a first achievement in history – China succeeded in launching two new satellites into space – Corgi dogs prices set records since the death of Queen Elizabeth II
The US space agency, NASA, reported the facts of a spacecraft colliding with an asteroid 11 million km from Earth.
In an unprecedented planetary defense test designed to teach humans how to prevent cosmic bodies from destroying life on Earth, the Dart spacecraft, as expected, deliberately collided with the asteroid Dimorphos.
In live transmission, the cameras on the spacecraft transmitted stunning images of the astronomical body that showed every detail of Dimorphos, including its gray surface and the small pebbles covering it. The moment the vehicle hit the asteroid and crashed into it, the transmission of images stopped. The Dart spacecraft has been traveling for ten months since it took off from California and until it hit the asteroid Dimorphos. The final stage of the flight was fully automated, transforming the Dart into a self-guided missile.
Since the asteroid Demorphos takes 11 hours and 55 minutes to make a complete orbit around the larger asteroid Didymos, NASA seeks, through the mission of its vehicle’s collision with this asteroid, to reduce this period by 10 minutes in order for Demorphos to approach the asteroid Didymos in its orbit and reduce the distance between them.
In the year 2026, the asteroid Demorphos will be monitored in particular by the European Hera probe, which is scheduled to be launched in 2024, in order to evaluate the consequences of the collision and calculate the mass of the asteroid for the first time.
Director of Planetary Sciences at NASA, Lori Glaze, pointed out that we have entered a new era in which we will have the ability to protect ourselves from the catastrophe of a dangerous asteroid collision with Earth, if we know that 66 million years ago, the dinosaurs disappeared after a large asteroid collided with the Earth with a diameter of about 10 kilometers.
So far, nearly 30,000 asteroids of all sizes have been spotted near Earth. Although a very small number of billions of asteroids and comets in the solar system do not pose a threat to the planet, the danger will become realistic in the next hundred years.
China successfully launched two new satellites into space on the 25th of last September. What are these satellites for?
From the Taiyuan space base in northern China, a Kuaizhou-1A rocket launched two test satellites, Shiyan-14 and Shiyan-15, into Earth orbits. These satellites will be used for scientific purposes, land surveys, urban planning, natural disaster prevention, and to test a range of new technologies.
For the 18th time in China’s history, Kuaizhou-1A rockets have been used to send satellites or spacecraft into Earth orbits.
It should be noted that China had recently carried out several space launches, most notably with the Long March 7A rocket, which installed the Zhongxing-1E satellite, which is intended for radio and television broadcasting services.
For the first time, prices of some Corgi dogs have touched $2,690 since Queen Elizabeth II’s memorial service.
Queen Elizabeth II owned about thirty corgi dogs for the rest of her life, the type that the late preferred, after she received in 1944 the first dog of this breed on her eighteenth birthday. Since that period, the popularity of the corgi dog breed has increased by 56%, only to return and its prices to jump significantly after the presentation of the series “The Crown”, which deals with the life of the Queen.
Prior to Elizabeth II’s death on September 8, the Queen had two Corgi dogs, Muick and Sandy, who appeared at her funeral at the entrance to Windsor Castle with two guards as the funeral procession passed. These dogs were adopted by the Queen’s youngest son, Prince Andrew, since he had given them to her.
In brief, the Corgi dog originated in southern Wales, one of the four constituent countries of the United Kingdom. This dog descended from guard dogs and herding dogs and his ancestors were from the Pembroke and Cardigan dog families.
Until 1934, Pembroke and Cardigan dogs were considered to be of the same breed. Since then, these two dogs are no longer considered to be of the same breed. The popularity of the welsh Corgi Pembroke increased and the Cardigan dog’s popularity was slowly declining. These two breeds are of medium size, with short feet and erect ears, and are very fox-like with their rounded faces and superior intelligence.
It should be noted that the Corgi dog needs constant stimulation and exercise training twice a day. When human interest in a Corgi declines, he becomes more prone to prolonged barking.
