VIDEO: Check out images about the new Chinese Z-20 helicopter

Diego Alves By Diego Alves 08/01/2022 - 08:00 in Helicopters, Military

The youtube channel "Military Fans in the World" released a video with an interesting video where we can observe different helicopters of Chinese military aviation, especially the Z-20, manufactured by the Aviation Industry Corporation of China (AVIC), located in Jingdezhen, Jiangxi Province, eastern China.

youtube

The description of the video informs that the main content of the video has an interview with Sun Dadong, pilot of the Z-20 helicopter, of the Army Aviation Brigade, subordinate to the Eastern Theater Command. In his point of view, the Z-20 has "an infinite energy, the DNA of a transport helicopter, the "blood" of an attack helicopter".

The video shows in addition to the Z-20, the Z-19 and Z-9, produced by Harbin, and the Z-10 that is produced by Changhe Aircraft Industries Corporation (CAIC).

It is also possible to see part of the training structure of Chinese rotary-wing aviation pilots.

A Large Object Landed on His Sheep Farm. It Came From Space.

https://sciencespies.com/space/a-large-object-landed-on-his-sheep-farm-it-came-from-space/

A Large Object Landed on His Sheep Farm. It Came From Space.

“It’s not something you see every day on a sheep farm,” a farmer said of the pieces of debris that wound up in rural Australia. They are thought to be from a SpaceX spacecraft.

Mick Miners was herding sheep on a four-wheeler last week when he stumbled upon a pointy black object that looked more than nine feet tall. It reminded him of either a burned tree or a piece of farm machinery.

“Pretty frightening, actually,” Mr. Miners, 48, said by phone on Thursday from his roughly 5,000-acre property in a remote corner of southeastern Australia.

“I was quite surprised,” he added. “It’s not something you see every day on a sheep farm.”

Mr. Miners took a picture and sent it to a neighboring farmer, Jock Wallace, who happened to have discovered a similarly mysterious object on his farm a few days earlier.

It was space debris.

The U.S. space agency, NASA, said in a statement that SpaceX confirmed that the object was likely the remaining part of the jettisoned trunk segment from a Dragon spacecraft used during the Crew-1 mission’s return from the International Space Station in May last year. “If you believe you have identified a piece of debris, please do not attempt to handle or retrieve the debris,” NASA said.

Space debris refers to equipment in space that no longer works. Most space debris burns up while re-entering the atmosphere, and much of what’s left over often falls in the ocean. However, with more spaceships entering orbit — such as those from private companies like SpaceX, founded by Elon Musk — impacts on land may happen more frequently. SpaceX did not respond to a request for comment.

Jonathan McDowell, an astrophysicist at the Center for Astrophysics in Cambridge, Mass., said that it’s not unusual for space debris to be found on land after an uncontrolled re-entry.

“It was a bit surprising to me that so much of the trunk survived the heating process of re-entry,” Dr. McDowell said, but he added that there was no indication that there was anything particularly risky about the trunk. He said that in the new commercial era for space exploration, it has been much harder to get technical information from private companies to assess risk. With more information, “we could have a better assessment of, ‘Did we just get really unlucky, or should we expect this from all the trunk re-entries if they happen over land?’”

The trunk segment, which is used to carry cargo and also includes the spacecraft’s solar arrays and radiators, is jettisoned from the body of the capsule shortly after the burn is completed when it goes out of orbit. “It typically burns up in the atmosphere over the open ocean, posing minimal risk to public safety,” the Federal Aviation Administration said in a statement.

NASA said that SpaceX confirmed that the object that landed in Dalgety, Australia, was likely Dragon hardware from the jettisoned trunk segment of its Crew-1 spacecraft.Brad Tucker via Reuters

Last week, after debris from a large Chinese rocket re-entered Earth’s atmosphere over the Indian Ocean, the administrator of NASA, Bill Nelson, issued a rebuke, saying that China “did not share specific trajectory information as their Long March 5B rocket fell back to Earth.” He added that all countries should “share this type of information in advance to allow reliable predictions of potential debris impact risk, especially for heavy-lift vehicles, like the Long March 5B, which carry a significant risk of loss of life and property.”

The possibility that debris from the rocket could have struck a populated area led people around the world to track its trajectory for days. This was the third flight of Long March 5B, China’s largest rocket, which made what is called “uncontrolled re-entry” back to Earth.

Last year, a malfunction caused a SpaceX rocket stage to complete an uncontrolled re-entry into Earth’s atmosphere near Seattle in what looked like bright objects lighting up the night’s sky. Pieces of the burning rocket debris landed on a farmer’s property in Washington State. The debris had re-entered the atmosphere after 22 days in orbit.

The rural area of Australia where Mr. Miners discovered the space debris on July 25 lies about 100 miles south of the capital, Canberra.

Ron Lane, who owns a restaurant in the town of Dalgety, said that most people in the area — with the notable exception of himself — were not especially worried about additional space debris potentially landing on them or their homes.

“If there’s three we know about, there could be another 10 we don’t know about,” Mr. Lane said by phone from his restaurant, Tuscany In Dalgety.

Mr. Miners, who was born on the farm where he discovered the unidentified debris, said that his neighbor, Mr. Wallace, had called the authorities to report the other debris that he had found on his own property earlier in July. Public interest grew, Mr. Miners said, after Mr. Wallace called the Australian national broadcaster, which later reported on the farmers’ discoveries and said that three pieces of debris had been found.

“Then everybody found out, and I’ve had about 300 calls,” said Mr. Miners, who has about 5,500 sheep, 100 cattle and 30 horses on his farm in the district of Numbla Vale.

His own piece of debris is almost 10 feet tall by 1.3 feet, he said, and an official from the Australian Space Agency called on Thursday to say that its experts planned to visit his property next week to “have a look at it.”

Mr. Miners said he had so far enjoyed learning the preliminary details about how the debris had landed and that he was not sure what would happen next.

He said he would be “happy to keep it” but was also interested in “a bit of compensation,” if the space agencies or company wanted it back.

Sa’id Mosteshar, a professor of international space law and the director of the London Institute of Space Policy and Law, said that a person would be able to claim compensation only if the debris harmed him or her or caused any damage to his or her property.

“My guess is they’ll want it back,” Mr. Miner added. “I don’t know. I don’t know anything about it. As I said, I’m a sheep farmer.”

Roundup: Reusable Rocket Vehicles - March.2024

I've gathered here recent news and updates on reusable rocket powered vehicles in operation and in development. Check out previous roundups: - Feb.26.2024 - Nov.17.2023 Rocket reusability will lead to space transports with aircraft-like operation. That is, orbital flight and return followed by rapid reflight with minimal preparation. Vehicles should fly thousands of times with only occasional refurbishment and, most importantly, spacefare should fall to levels similar to long distance airfare. Reusable rocket powered vehicle designs fall roughly into the following five categories: - Partially reusable orbital transport: - Operational: SpaceX Falcon 9 - In development: Blue Origin New Glenn, Rocket Lab Electron and Neutron, Relativity Space Terran-R, etc. - Fully reusable orbital transport: - In development: SpaceX Starship, Stoke Space Nova - Reusable spacecraft: (incl. space tugs, fuel depots, etc.): - Operational: Crew/Cargo Dragons, Boeing/USAF X-37 spaceplane, Chinese spaceplane - In development: Boeing Starliner, Sierra Space Dreamchaser, ESA Space Rider, Spacebilt, India spaceplane, etc - Fully reusable suborbital: - Operational high altitude: Blue Origin New Shepard, Virgin Galactic SpaceShipTwo - Operational low altitude: Astrobotic VTVL rockets, Exos Aerospace, Landspace (China), etc - Fully reusable hypersonic suborbital for long distance point-to-point transport: - In development: Venus Aerospace Stargazer, POLARIS Aurora, New Frontier Aerospace, etc. Below are reports on several projects and programs that fall into at least one of these categories. ** SpaceX Starship - Third test flight shows major progress ---- The third orbital test flight (OFT-3) successfully demonstrated several key Starship capabilities On March 14th, SpaceX flew a Starship for the third time. The flight test fulfilled a number of goals beyond those accomplished in the previous two flights. See this SpaceX overview: Starship's Third Flight Test | SpaceX - Mar.14.2024 OFT-3 highlights: - For second time, all 33 Raptor engines on the Super Heavy booster fired from liftoff through hot-stage separation. - The separation again went well, with the Starship upper stage successfully lighting its six Raptors and continuing towards orbit. - After the hot-stage separation: - The booster did a flip maneuver and completed a boostback burn to propel itself towards the splashdown target in the Gulf. In the second test flight, while the booster was orienting itself for the boostback burn, its engines began to turn off and one blew up, destroying the entire vehicle. - As the the booster neared the surface of the Gulf, it began to light up engines for a soft landing onto the Gulf waters and then sink to the bottom. At a few hundred meters above the surface, something happened and "the vehicle experienced a RUD (that’s SpaceX-speak for “rapid unscheduled disassembly”)". As of the time of this posting, SpaceX has not revealed what caused the RUD. - Following the separation, the Starship upper stage continued firing its engines for the full duration and reached a near orbital velocity when the engines were shut down. - Video imagery via Starlink showed the vehicle rotating slowly around its long axis. - SpaceX planned to fire a Raptor to demonstrate a powered de-orbit but they canceled the firing due to the rotation. - The orbit had a low perigee that brought it into the atmosphere and caused Starship to reenter over the Indian Ocean even without the de-orbit engine thrust. - As the vehicle entered the atmosphere, the video displayed the bright glow of the hot gasses around the vehicle. - The vehicle struggled to maintain its orientation and began tumbling. Eventually the video and data connection died and presumably the breakup of the vehicle began soon after. During the coast phase in orbit, two important tests were carried out: - Opening and closing the Starship’s payload door, which will be needed for Starlink Gen 2 satellite deployments. - A propellant transfer demonstration. ---- FAA suspends Starship license until an investigation into the problems of this flight is completed. This happens automatically if there is any variation from the approved flight plan significant enough to be classified as a mishap: - SpaceX Starship Third Flight: Mishap Investigation by FAA | Leonard David - Mar.15.2024 - SpaceX Starship Grounded Again | FLYING Magazine - Mar.15.2024 The mishap investigation should not significantly increase the time to the launch of the fourth Starship since both stages achieved their primary goals and the problems were not as serious as for the first two test flights. SpaceX will actually do the investigating and the FAA will then evaluate the results. If they are deemed satisfactory, the FAA issues a statement about the completion of the investigation and sometime after that they issue a modification to the current launch license that approves another flight. It should be pointed out that the Starship is basically operational now as an expendable launch vehicle. The boosters functioned properly through stage separation and the second stage on OFT-3 would have reached a full orbit with just a brief extension of the firing of the Raptors. Reusability, however, is key to SpaceX's plans for the vehicle and it won't be declared operational until the booster does a soft landing and the Starship stage survives reentry and makes a soft landing as well. ---- SpaceX expects to be ready for 4th test flight by early May: SpaceX planning rapid turnaround for next Starship flight | SpaceNews - Mar.19.2024 Speaking at the Satellite 2024 conference March 19, Gwynne Shotwell, president and chief operating officer of SpaceX, said the company was still reviewing the data from the vehicle’s third integrated launch March 14 but expected to be ready to fly again soon. “We’re still going through the data” from the flight, she said when asked about the analysis of data from the mission. “It was an incredibly successful flight. We hit exactly where we wanted to go.” ... “We’ll figure out what happened on both stages,” she said, not discussing what may have gone wrong with either, “and get back to flight hopefully in about six weeks,” or early May. Shotwell doubted they would launch any Starlink satellites during the mission. Speaking at the Space Capitol III event by Payload March 18, Kelvin Coleman, FAA associate administrator for commercial space transportation, said he did not anticipate that investigation to turn up any major issues that could significantly delay the next launch. The FAA also hopes to move soon to a license that covers multiples flights ... Coleman said the agency wants to move to a process where the license is valid for “portfolio of launches” rather than individual ones. That is particularly important, he added, because SpaceX is planning six to nine more Starship launches this year. That is part of a broader effort to streamline the launch licensing process to address criticism from industry and Congress that the FAA is moving too slowly on approving launch licenses under a new set of regulations known as Part 450. ... Preparations for the fourth test are underway: Following IFT-3 milestones, SpaceX prepares for fourth Starship flight | NASASpaceFlight.com - Mar.22.2024 SpaceX is preparing to follow up its third flight of Starship – one that achieved another leap forward with the world’s largest rocket in history – with the IFT-4 mission. Potentially as early as May, the fourth flight is expected to pair Booster 11 with Ship 29, with the latter already back at the launch site for its Static Fire test campaign. A static firing test of the 6 Raptor engines on Ship 29 took place on March 25th : Full-duration static fire of all six Raptor engines on Flight 4 Starship pic.twitter.com/HzS4SeaoEV — SpaceX (@SpaceX) March 25, 2024 https://youtu.be/cvagnihR0WE ---- Another test firing, this time of only one engine, took place on March 27th. This presumably tests for a de-orbit firing. STATIC FIRE 2 for Ship 29. This time it does indeed look like the in-space firing test with a single Raptor. That may conclude Static Fire testing for the Ship ahead of IFT-4.https://t.co/skVzGw4vkS pic.twitter.com/o3wOcVEojn — Chris Bergin - NSF (@NASASpaceflight) March 27, 2024 ---- OFT-3 Videos: - Launch through booster landing attempt and shutdown of Starship upper stage engines: Blastoff!

Chinas Wayward Rocket Has Disintegrated Over the Pacific Ocean

The launch of a Lengthy March 5B rocket on April 28, 2021. Photograph: Chinatopix (AP) The booster from a Chinese language Lengthy March 5B rocket reentered Earth’s ambiance at 6:01 a.m. ET Friday, with particles falling west of the Mexican coast. There are not any experiences of accidents, however the 22-metric-ton core stage threatened populated areas throughout its closing orbit. U.S. Area Command confirmed the booster’s atmospheric reentry by means of Twitter, saying it fell over the south-central Pacific Ocean. Apparently, Area Command tracked a second atmospheric reentry linked with the Lengthy March 5B rocket, suggesting the rocket snapped into two giant items. The percentages have been good that the 108-foot-long (33-meter) booster would come down over the ocean, as two-thirds of Earth is roofed in water. Nonetheless, China is selecting to play with folks’s lives and property, designing a rocket that, as a substitute of performing a protected and managed reentry after launch, flies right into a quickly decaying orbit. The rocket, carrying the third and closing module for China’s Tiangong area station, launched from Wenchang Area Launch Middle in Hainan on October 31. This marks the fourth event {that a} Lengthy March 5B rocket has entered into an uncontrolled state. G/O Media could get a fee Mission controllers had no approach to management the booster as soon as it entered orbit, forcing consultants to foretell the place and when it would land, which is notoriously tough to do. By yesterday night, most projections had the booster reentering round 12:00 p.m. ET at this time, give or take a couple of hours. The rocket, falling at 6:01 ET this morning, fell properly prematurely of the estimates churned lower than a half day earlier than it lastly dove into the ambiance at speeds reaching 17,500 miles per hour (28,160 kilometers per hour). Particles fell to the southwest of the Mexican coast, close to 2.2 S 114.1 W. The booster was transferring in a northeastly route on the time, and had it stored going it could have flown over Mexico and components of the US. Particles footprints aren’t small, with widths typically reaching 44 miles (70 km) huge and over 1,240 miles (2,000 km) in size, Ted Muelhaupt, a marketing consultant with Aerospace’s Company Chief Engineer’s Workplace, advised reporters on Wednesday. Muelhaupt mentioned that between 10% and 40% of the booster was prone to survive reentry. Throughout its closing orbit, the core stage flew over Spain, Saudi Arabia, and western Australia. Spain quickly closed a part of its airspace because the booster flew overhead, in accordance to Reuters. Nobody was harm (so far as we all know), however the wayward booster did lead to inconvenience. That is the fourth incident involving an out-of-control Lengthy March 5B core stage. Two years in the past, particles from the inaugural launch of the rocket fell onto the Ivory Coast, reportedly inflicting harm to property. Particles from the second flight fell harmlessly into the Indian Ocean, however the reentry from the third flight in July 2022 was seen from Malaysia, with harmful bits of area junk raining down onto components of Indonesia and Philippines.

Problematic Launch Anticipated as China Finalizes Area Station

China’s Lengthy March 5B rocket heading to the launch pad on Tuesday. Screenshot: CCTV/CNSA China rolled out its Lengthy March 5B rocket on Tuesday in anticipation of its upcoming liftoff to put the third and last piece of the Tiangong area station in orbit. It’s all very thrilling, however an out-of-control core module will doubtless end result, as was the case on three earlier events. The heavy-lift rocket was transported to the pad on Tuesday, carrying a 23-ton lab module named Mengtian (which interprets to “dreaming of heavens”). It took about three hours for the Lengthy March 5B to make the almost 2 mile (3 kilometer) journey on the Wenchang Spacecraft Launch Website, in response to China Nationwide Area Administration (CNSA). On the pad, the rocket will bear last checks and fueling in preparation for its launch. The area company has not confirmed the precise date for launch, however earlier statements counsel the rocket will take off on Monday, October 31, in response to Area.com. Mengtian will be part of its sister modules Wentian and Tianhe to kind the T-shaped construction of China’s three-module area station named Tiangong (which means “heavenly place”). China’s area company will use the Mengtian lab to conduct varied microgravity experiments associated to fluid physics, combustion science, and area expertise, in accordance to China’s state-run Xinhua. Not like Tianhe, Mengtian doesn’t embrace dwelling quarters for astronauts. Tiangong is China’s reply to the Worldwide Area Station and is scheduled to be absolutely constructed by the top of the 12 months. The primary module of the area station, Tianhe, launched to orbit in April 2021, whereas Wentian adopted greater than a 12 months later in July 2022. G/O Media could get a fee In June, China despatched a crew of three astronauts to the area station the place they’ve spent the previous a number of months overseeing the docking of the 2 modules, along with setting them up and operating assessments. The crew is anticipated to return to Earth in December, after which level the Shenzhou-15 crew will take over. Much like earlier launches of China’s Lengthy March 5B , the core stage is predicted to carry out an uncontrolled reentry by way of Earth’s environment upon its return. Astronomer Jonathan McDowell from the Harvard-Smithsonian Heart for Astrophysics is “95% sure we will likely be in precisely the identical scenario once more,” he instructed Gizmodo in an electronic mail. The Lengthy March 5B is infamous for jeopardizing populated areas because it falls again to Earth in a haphazard state. Earlier incidents have taken place in 2020 and 2021 through which particles from the 100-foot-long (30-meter) core stage crashed alongside the western coast of Africa and the Indian Ocean. This previous August, particles from the Lengthy March 5B fell throughout areas in northern Borneo. Mercifully, nobody has been harm, however that doesn’t imply it could’t occur. China is making enormous inroads in area, however its area company continues to be reckless with regards to its rockets. Rockets are sometimes constructed with mechanisms to regulate their reentry to remoted areas, or sluggish them down as they make their manner again to Earth. If China plans on sending extra of its heavy-elevate rockets to orbit, it wants to begin higher equipping them for the experience again.

A big piece of Chinese space junk has crashed back to Earth.

The 25-ton (22.5 metric tons) core stage of a Long March 5B rocket reentered Earth's atmosphere over the Indian Ocean this afternoon (July 30), ending its brief but controversial orbital stay.

"#USSPACECOM can confirm the People’s Republic of China (PRC) Long March 5B (CZ-5B) reentered over the Indian Ocean at approx 10:45 am MDT [12:45 p.m. EDT; 1645 GMT] on 7/30," the U.S. Space Command announced via Twitter today(opens in new tab). "We refer you to the #PRC for further details on the reentry’s technical aspects such as potential debris dispersal + impact location."

The Long March 5B lifted off on July 24, carrying a new module toward China's under-construction Tiangong space station. Unlike the core stages of most rockets, which are steered to a safe disposal shortly after launch or land softly for future reuse, the Long March 5B reached orbit along with its payload. And it stayed up — as a big, fast-moving piece of space junk — until atmospheric drag brought it down in an unpredictable and uncontrolled fashion.

Mission managers didn't screw anything up; this end-of-life scenario is built into the Long March 5B's design, to the consternation of exploration advocates and much of the broader spaceflight community. This disposal strategy is reckless, critics say, given that the big rocket doesn't burn up completely upon reentry.

Indeed, 5.5 tons to 9.9 tons (5 to 9 metric tons) of the Long March 5B likely survived all the way to the ground today, experts with The Aerospace Corporation's Center for Orbital Reentry and Debris Studies have estimated(opens in new tab).

And it's possible that falling rocket chunks caused some injuries or infrastructure damage today, given where the Long March 5B reentered. One observer appeared to capture the rocket's breakup from Kuching, in the Malaysian state of Sarawak, for example, posting video of the dramatic event on Twitter(opens in new tab).

"The video from Kuching implies it was high in the atmosphere at that time — any debris would land hundreds of km further along track, near Sibu, Bintulu or even Brunei," astrophysicist and satellite tracker Jonathan McDowell, of the Harvard-Smithsonian Center for Astrophysics, said via Twitter today(opens in new tab). It's "unlikely but not impossible" that one or more chunks hit a population center, he added in another tweet(opens in new tab).

Chinese space officials, for their part, said(opens in new tab) the rocket body reentered at 119.0 degrees east longitude and 9.1 degrees north latitude. That location is over open ocean, just off the coast of Palawan Island, which is part of the Philippines.

We'll have to wait a while to see exactly where the rocket debris came down. But the fact that the crash occurred at all does not reflect well on China and its spaceflight program, experts say.

"What really should have happened is, there should have been some fuel left on board for this to be a controlled reentry," Darren McKnight, a senior technical fellow at the California-based tracking company LeoLabs, said Thursday (July 28) during a Long March 5B reentry discussion that The Aerospace Corporation livestreamed on Twitter. "That would be the responsible thing to do."

NASA Administrator Bill Nelson voiced similar sentiments, calling out China in a statement issued today(opens in new tab) shortly after the reentry.

"The People’s Republic of China (PRC) did not share specific trajectory information as their Long March 5B rocket fell back to Earth," Nelson said.

"All spacefaring nations should follow established best practices, and do their part to share this type of information in advance to allow reliable predictions of potential debris impact risk, especially for heavy-lift vehicles, like the Long March 5B, which carry a significant risk of loss of life and property," he added. "Doing so is critical to the responsible use of space and to ensure the safety of people here on Earth."

This was the third uncontrolled fall for a Long March 5B core stage to date. About 10 days after the rocket's debut launch, in May 2020, pieces of the rocket body rained back to Earth over West Africa, some of them apparently hitting the ground in Ivory Coast(opens in new tab).

The rocket's second flight, in April 2021, lofted Tianhe, the core module of the Tiangong space station. That Long March 5B body reentered over the Arabian peninsula about a week after liftoff, dumping debris over the Indian Ocean.

The rocket will fly again soon as well: A Long March 5B is expected to launch the third and final Tiangong module this fall. There will probably be more Chinese space junk drama after that, but perhaps not for too much longer.

"I do see China slowly adopting the norms of other countries in space," McDowell said during Thursday's Aerospace Corporation discussion.

"And I think it's important to remember that they were sort of a latecomer to space activities," McDowell added. "And so they're catching up, and I think they're catching up in norms as well."

Update on Chinese Rocket Crash - May 9, 2021

Update on Chinese Rocket Crash – May 9, 2021

As an update to an earlier post yesterday – A huge Chinese rocket booster is falling from space, but don’t worry. It likely won’t hit you. – Space.com May 7, 2021 – Space Saturdays May 8, 2021, looks like the rocket crashed near the Maldives in the Indian Ocean: https://www.bbc.com/news/science-environment-57045058. Slightly longer article, but here’s what I considered relevant. The remains of a…
