(Source: space.com) According to the Vietnam News Agency reporter in Tokyo, Japan in 2030 will launch a rocket with propulsion recycled from engines used in previous missions, in order to reduce costs rocket launch . Kyodo news agency citing unnamed sources said that a panel of experts from the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) is expected to put the goal of building the missile. be equipped with recycled propulsion in an interim report drafted on May 12. The current, rocket launch costs Japan’s H2A is very expensive because the rocket propulsion will be disposed of after the missile is launched. Even the H3 – the country’s next-generation missile and expected to be launched by the end of March 2022 – is disposable. Meanwhile, the Falcon 9 missile developed by the American Space Exploration Corporation, can reuse parts that have been used in previous missions to bring astronauts, including Japanese astronaut Akihiko Hoshide, boarded the International Space Station (ISS) last month. Since the propulsion of the Falcon 9 rocket is about 10 times reusable, the cost of launching the missile is only about 6 billion yen ($ 55 million), half of the launch cost. H2A rockets Japanese. So the Japan Aerospace Research and Development Agency (JAXA) is conducting research on how to launch a small test missile to a height of about 100 meters and then land vertically in an attempt. missile reuse force. In addition, JAXA also plans to test reusable missiles on a large scale, possibly with France and Germany in 2022./.

On April 29, at the Van Xuong spacecraft launch center in Hainan province, China successfully launched the first module of the Tianhe space station with the Truong Chinh 5B rocket, marking an important step in the build the country’s own space station. However, instead of falling to a predetermined place in the sea like the previous rockets, the central stage of the Truong Chinh 5B boosters started spinning around the Earth in a low orbit in a state of out-of-control. With a weight of about 21 tons, 30m long and 5m wide, the remnants of the Truong Chinh 5B rocket are flying in orbit around the Earth every 90 minutes / rev, at a speed of 27,600 km / h at an altitude of over 300 kilometer. Since the end of last week until now, this remaining part has decreased altitude by nearly 80km. According to the observations of underground amateur astronomers, this missile is in a very unstable state. Some calculations show that the central floor of the Truong Chinh 5B missile will plunge into the atmosphere on May 8. When it crosses the Earth’s atmosphere, it could be burned, but it is likely that large pieces of the missile will remain and will fall scattered over an area of ​​160km wide. Worth mentioning, this is not the first time that China’s Truong Chinh 5B missile has fallen into a state of out-of-control during the biosphere. In May 2020, a similar incident happened. Beijing is expected to have at least 10 more similar launches, bringing all additional equipment into orbit, before completing the station by 2022. China’s Truong Chinh 5B missile was launched into orbit on April 29 at the Wenchang launch pad, southern China. . Prior to the US Space Command’s forecast that the 2021-035B Truong Chinh 5B (Long March 5B or Chang Zheng 5B) missile core, called 2021-035B, was capable of falling uncontrollably on Earth on the day. May 8-9, many people questioned: Will Russia or the US plan to use the missile to shoot the core of the Truong Chinh 5B missile, to save the planet’s citizens? On May 6, the US said it was tracking the object’s path, but had no plans to shoot it down. Cosmic garbage Australia currently holds the record as the country that contains the largest space waste in the world. In 1979, the 77-ton American SkyLab space station disintegrated in Western Australia, leaving the area around the coastal town of Esperance splashed by debris. Although no deaths or serious injuries have been reported from being hit by these cosmic debris, it is quite dangerous. Just a year before the fall of SkyLab, a Soviet remote sensing satellite, Cosmos 954, crashed into a barren area of ​​Canada’s Northwest Territory, spreading radioactive debris over several hundred square kilometers. As the Cold War was at its height, the nuclear sensitivity of the Cosmos 954 led to unfortunate delays in locating and cleaning the wreck. Who has to pay for cleaning? International law sets out a compensation regime that applies in many cases of damage on Earth, as well as when satellites collide in space. The 1972 conventions, a United Nations treaty, impose liability for the damage caused by space debris, which includes a regime of absolute liability as they fall to Earth like fragments. crumbs. In the case of Long March 5B, this would impose potential liability on China. The new treaty has only been invoked once before (for the Cosmos 954 incident) and therefore may not be considered a incentive. Of course, this legal framework only applies after the damage has occurred. In 1978, a Soviet nuclear-powered satellite crashed in northern Canada, resulting in a $ 3,000,000 fine for the tundra radioactive cleanup for Canada.

“The test was done with a script dealing with an external air attack. As soon as it detected and locked the target, the fighter launched Bozdogan. The missile hit the target with absolute precision. “The Turkish Air Force said in a statement.

Self-produced rocket launchers F-16 Earth.

The source added that, prior to this exemplary interception, Bozdogan also successfully conducted many other interceptions when launched from fixed platforms on the ground.

These are state tests before they enter service. The results of the Bozdogan development program have made not only the manufacturer, the Air Force but also President Recep Tayyip Erdogan very pleased.

“When officially put into service, Ankara will have a weapon that no other country has. In particular, this missile will replace the US-made AIM-120 AMRAAM, AIM-9X ammunition. served in the Turkish Air Force, “Erdogan said.

According to Drive, not only the US-made AIM-120 AMRAAM and AIM-9X are gradually being replaced in Turkey, but the legendary American anti-ship missile Harpoon also suffers the same fate in the Turkish Navy.

Specifically, on the new generation of Turkish Milgem-class warships, Harpoon is replaced by the Atmaca (Hawk) missile line researched and developed by Turkish defense contractor Roketsan.

It is known that Atmaca is the first anti-ship missile produced by Turkey. It can glide through ships before hitting and destroying any warship it targets.

At first glance, the Atmaca missile looks quite similar to Russia’s Harpoon or Kh-35 anti-ship missiles. Like other rockets, Atmaca is launched from a launcher using a rocket engine, helping to propel the missile to move at high speed.

After finishing the propulsion process, the jet engine will be activated and help the missile fly to the target position. Thanks to the integration of an altimeter radar, the missile can fly just above the waves easily to avoid being shot down when attacking enemies. Roketsan officially developed the Atmaca missile since 2009.

The missile can operate in all weather conditions, highly effective against moving and fixed targets at sea. The maximum range of the Atmaca is believed to be about 250km – this range is much further than the AGM-84 Harpoon.

“A powerful Turkey needs to have state-of-the-art weapons of its own in order not to be dependent on external supply, even though those countries are known as close allies.

In some areas that are not yet our strengths, such as defensive weapons and fighters, Ankara will seek partners that are more reliable and not affected by political factors, “said a member of the company. Turkey’s ruling Justice and Development Party (AKP) said.

From the statement of the AKP representative showed that this is the reason why Turkey decided to carry out the deal of Russia’s S-400 interceptor system despite the US and some NATO members threatening sanctions. .

In addition, the Turkish Air Force is currently negotiating with the Russian side on the fighter deal. It is not clear that this NATO member is looking to buy Russian Su-35 fighter or Su-57 stealth fighter.
