5 min read NASA, Pacific Disaster Center Increase Landslide Hazard Awareness Communities worldwide now have access to a powerful tool to increase their awareness of landslide hazards, thanks to NASA and the Pacific Disaster Center. A humanitarian worker from USAID observes the impacts of a landslide. USAID deployed an elite Disaster Assistance Response Team on Nov. 17, 2020, to lead the U.S. response to Hurricanes Eta and Iota.USAID’s Bureau for Humanitarian Assistance After years of development and testing, NASA’s Landslide Hazard Assessment for Situational Awareness model (LHASA) has been integrated into the Pacific Disaster Center’s (PDC) multi-hazard monitoring, alerting, and decision-support platform, DisasterAWARE. LHASA allows researchers to map rainfall-triggered landslide hazards, giving DisasterAWARE users around the world a robust tool for identifying, tracking, and responding to these threats. The aim is to equip communities with timely and critical risk awareness that bolsters disaster resilience and safeguards lives and livelihoods. Landslides cause thousands of deaths and billions of dollars in damage every year. Developing countries often bear disproportionate losses due to lack of access to hazard early warning systems and other resources for effective risk reduction and recovery. Reports from the United Nations Office for Disaster Risk Reduction emphasize that early warning systems and early action are among the most effective ways to decrease disaster-related deaths and losses. The distribution of reported fatalities from 10,804 rainfall-triggered landslides in NASA’s Global Landslide Catalog (GLC) from 2007 to 2017. White dots represent incidents with zero reported fatalities and dots in the color scale from pink to red represent incidents in the range of 1-5000 fatalities. The NASA landslides team, based primarily out of NASA’s Goddard Space Flight Center, develops the Global Landslide Catalog and LHASA with support from NASA’s Disasters program. NASA Scientific Visualization Studio “Some local authorities develop their own systems to monitor landslide risk, but there isn’t a global model that works in the same way. That’s what defines LHASA: it works all the time and it covers most regions of the world,” says Robert Emberson, NASA Disasters associate program manager and a key member of the NASA landslides team. “Thanks to our collaboration with the Pacific Disaster Center, this powerful landslide technology is now even more accessible for the communities that need it most.” LHASA uses a machine learning model that combines data on ground slope, soil moisture, snow, geological conditions, distance to faults, and the latest near real-time precipitation data from NASA’s IMERG product (part of the Global Precipitation Measurement mission). The model has been trained on a database of historical landslides and the conditions surrounding them, allowing it to recognize patterns that indicate a landslide is likely. The result is a landslide “nowcast” – a map showing the potential of rainfall-triggered landslides occurring for any given region within the past day. This map of hazard likelihood can help agencies and officials rapidly assess areas where the current landslide risk is high. It can also give disaster response teams critical information on where a landslide may have occurred so they can investigate and deploy life-saving resources.   In 2021, a 7.2 magnitude earthquake struck Haiti, triggering a series of landslides across the country. Landslides can destroy infrastructure and impede the movement of people and life-saving aid. United Nations World Food Programme Partnering to Protect the Vulnerable Generating landslide nowcasts is merely the first step. To be truly effective, vulnerable communities must receive the data in a way that is accessible and easy to integrate into existing disaster management plans. That’s where the Pacific Disaster Center comes in. PDC is an applied research center managed by the University of Hawaii, and it shares NASA’s goal to reduce global disaster risk through innovative uses of science and technology.  Its flagship DisasterAWARE software provides early warnings and risk assessment tools for 18 types of natural hazards and supports decision-making by a wide range of disaster management agencies, local governments, and humanitarian organizations. Prominent users include the International Federation of Red Cross and Red Crescent Societies (IFRC), the United Nations Office for the Coordination of Humanitarian Affairs (UN OCHA), and the World Food Programme (WFP). “The close pairing of our organizations and use of PDC’s DisasterAWARE platform for early warning has been a special recipe for success in getting life-saving information into the hands of decision-makers and communities around the world,” said Chris Chiesa, PDC deputy executive director. The collaboration with PDC brings NASA’s landslide tool to tens of thousands of existing DisasterAWARE users, dramatically increasing LHASA’s reach and effectiveness. Chiesa notes that teams in El Salvador, Honduras, and the Dominican Republic have already begun using these new capabilities to assess landslide hazards during the 2023 rainy season. This screenshot from PDC’s DisasterAWARE Pro software shows LHASA landslide hazard probabilities for Myanmar in Sept. 2023. Red areas indicate the highest risk for landslide occurrence within the past three hours, while orange and yellow indicate lesser risk. Pacific Disaster Center PDC’s software ingests and interprets LHASA model data and generates maps of landslide risk severity. It then uses the data to generate landslide hazard alerts for a chosen region that the DisasterAWARE mobile app pushes to users. These alerts give communities critical information on potential hazards, enabling them to take protective measures. DisasterAWARE also creates comprehensive regional risk reports that estimate the number of people and infrastructure exposed to a disaster – focusing specifically on things like bridges, roads, and hospitals that could complicate relief efforts when damaged. This information is critical for allowing decision-makers to effectively deploy resources to the areas that need them most.  DisasterAWARE landside risk report for Myanmar, showing estimated population, infrastructure and capital exposure to landslide risk, as well as the community’s needs. Pacific Disaster Center This effort between NASA and the PDC builds upon a history of fruitful cooperation between the organizations. In 2022, they deployed a NASA global flood modeling tool to enhance DisasterAWARE’s flood early-warning capabilities. They have also shared data and expertise during multiple disasters, including Hurricane Iota in 2020, the 2021 earthquake in Haiti, and the devastating August 2023 wildfires in Maui, PDC’s base of operations. “The LHASA model is all open-source and leverages publicly available data from NASA and partners,” says Dalia Kirschbaum, lead of the NASA landslides team and director of Earth Sciences at NASA’s Goddard Space Flight Center. “This enables other researchers and disaster response communities to adapt the framework to regional or local applications and further awareness at scales relevant to their decision-making needs.” Kirschbaum and her team were recently awarded the prestigious NASA Software of the Year award for their work developing LHASA.  Share Details Last Updated Oct 26, 2023 Related Terms EarthNatural Disasters Explore More 3 min read International Ocean Satellite Monitors How El Niño Is Shaping Up Article 1 week ago 3 min read All Together Now: Drill Joins Other Moon Rover Science Instruments Article 1 week ago 2 min read NASA’s Global Science Hackathon Attracts Thousands of Participants Article 3 weeks ago 5 min read NASA, Pacific Disaster Center Increase Landslide Hazard Awareness

Although this scenario is realistic in many ways, it is completely fictional and does NOT describe an actual potential asteroid impact!

Gizmodo: Asteroid Impact Simulation Has Ended In Disaster

An international exercise to simulate an asteroid striking Earth has come to an end. With just six days to go before a fictitious impact, things don’t look good for a 185-mile-wide region between Prague and Munich.

Scientists Tried and Failed to Stop a Hypothetical Deadly Asteroid in an Exercise

It’s the Doomsday event that reigns supreme over all others: An asteroid, on a collision course with Earth, is discovered with very little time to prevent a possible impact. 

In addition to being wonderful fodder for blockbuster movies, this scenario was also the inspiration for a tabletop exercise with NASA scientists at the International Academy of Astronautics' Planetary Defense Conference last week. The asteroid drill is a mainstay of the biennial conference, but this year was different for two reasons: 1) The event was held virtually due to the COVID-19 pandemic, and 2) the fictional 2021 asteroid could not be stopped despite the scientists’ best efforts, even with a nuclear option.

“The exercise played out that we basically had to take the hit,” said Lindley Johnson, NASA’s Planetary Defense Officer, in a call, noting that it was among the “more challenging scenarios” ever presented at the conference.

“One of the objectives of this exercise is to get the disaster management and emergency response community more involved and thinking about what they would be facing if we didn't have the time to divert an asteroid in space, and did have to take the impact somewhere,” Johnson added.

Details about this hypothetical space rock, dubbed 2021 PDC, were devised by the Center for Near-Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory, which helpfully emphasized that the asteroid “does not exist and therefore there is no threat to Earth” in a summary of the four-day event.

On April 26, the first day of the exercise, participants learned that the asteroid was anywhere from 35 meters (100 feet) to 700 meters (2,000 feet) wide, and that it had a one-in-20 chance of impacting Earth around October 20 of this year.

While those initial 1-20 odds might sound good, the news got grim on the second day, which involved an imaginary time jump to May 2. New observations of 2021 PDC revealed that it had a 100 percent chance of hitting Europe or Northern Africa in just six months. 

The extremely short notice made it impossible for the tabletop team, which involved hundreds of people, to develop and launch a mission that could deflect or disrupt the hazardous space rock in time. 

“To mount a campaign, even a single mission, given our current state of the technology and how we do these deep space missions, we need a lead time, I would say, of a minimum of two years, and we’d be much more comfortable if it were five years,” Johnson said.

More bad omens emerged on day three of the simulation, which fast-forwarded to International Asteroid Day on June 30: The asteroid was predicted to crash somewhere inside the relatively populated region of central Europe. 

By day four, the participants were situated within a week of impact, and discussions focused on evacuations and disaster response within the revised crash zone, south of Prague.

According to a report generated during the exercise, the deflection option wasn’t viable because it would require sending a spacecraft to nudge the asteroid off-course much further in advance of the impact than the allotted six months. The report noted that a nuclear explosive device sent to disrupt the asteroid is “the only viable mitigation option in very short warning scenarios,” but after robust calculations, that option was also ruled impractical in this instance. 

As a result, the team recommended the development of rapid response spacecraft launches that could blast off within days or weeks of notice.

That said, the tabletop exercise demonstrated that even worst-case scenarios still present many opportunities to mitigate casualties and damage. If that seems like cold comfort, take solace in the fact that Johnson and his colleagues are working on many projects that will further reduce the already extremely low odds that such a hazardous asteroid will threaten our civilization any time soon.

Later this year, NASA will launch the Double Asteroid Redirection Test (DART), a mission that will lay the basic groundwork for any future attempts to deflect asteroids away from trajectories that pose a threat to Earth. DART will slam into a small asteroid that is orbiting a larger asteroid, in a system known as Didymos, providing a safe way to experiment with this planetary defense strategy.  

In addition, the Near-Earth Object Surveillance Mission (NEOSM), due for launch in the mid-2020s, will scan the solar system for any potentially hazardous asteroids from its perch between Earth and the Sun. Missions such as NEOSM are designed to prevent the types of imminent emergencies presented in the latest tabletop exercise by providing scientists with ample time to prepare for dangerous encounters.

“We do have the technology to find any significant impactor well in advance—years, if not decades in advance,” said Johnson. “Part of all this is to get folks to understand that the further out in time that we find a potential impactor, the bigger chance and the more possibilities we have to do something about it in space, and never have to suffer those consequences.”

Hypothetical asteroid devastates Europe in doomsday NASA simulation

Hypothetical asteroid devastates Europe in doomsday NASA simulation

Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth.

A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.

With each passing day of the exercise, the participants learned more about the asteroid’s size, trajectory, and chance of impact. Then they had to cooperate and use their technological knowledge to see if anything could be done to stop the space rock.

The experts fell short. The group determined that none of Earth’s existing technologies could stop the hypothetical asteroid from striking given the six-month timeframe of the simulation. In this alternate reality, the asteroid crashed into eastern Europe.

As far as we know, no asteroids currently pose a threat to Earth in this way. But an estimated two-thirds of asteroids 140.21m in size or bigger – large enough to wreak considerable havoc – remain undiscovered. That’s why NASA and other agencies are attempting to prepare for such a situation.

“These exercises ultimately help the planetary-defense community communicate with each other and with our governments to ensure we are all coordinated should a potential impact threat be identified in the future,” Lindley Johnson, NASA’s planetary defense officer, said in a press release.

Six months is not enough time to prepare for an asteroid impact

The fictitious asteroid in the simulation was called 2021PDC. In NASA’s scenario, it was first “spotted” on April 19, at which time it was thought to have a 5 percent chance of hitting our planet on October 20, six months after its discovery date.

But Day 2 of the exercise fast-forwarded to May 2, when new impact-trajectory calculations showed that 2021PDC would almost certainly hit either Europe or northern Africa. The participants in the simulation considered various missions in which spacecraft could try to destroy the asteroid or deflect it off its path.

They concluded that such missions wouldn’t be able to get off the ground in the short amount of time before the asteroid’s impact.

“If confronted with the 2021PDC hypothetical scenario in real life, we would not be able us to launch any spacecraft on such short notice with current capabilities,” the participants said.

They also considered trying to blow up or disrupt the asteroid using a nuclear explosive device.

“Deploying a nuclear disruption mission could significantly reduce the risk of impact damage,” they found.

Still, the simulation stipulated that 2021PDC could be anywhere from 34.75m to half a mile in size, so the chance that a nuke could make a dent was uncertain.

Day 3 of the exercise skipped ahead to June 30, and Earth’s future looked grim: 2021PDC’s impact trajectory showed it headed for eastern Europe.

By Day 4, which fast-forwarded to a week before the asteroid impact, there was a 99 percent chance the asteroid would hit near the border between Germany, the Czech Republic, and Austria. The explosion would bring as much energy as a large nuclear bomb.

All that could be done was evacuate the affected regions ahead of time.

Most asteroids fly under the radar, and many are spotted too late

It’s tempting to assume that in the real world, astronomers would spot an asteroid akin to 2021PDC with much more notice than six months. But the world’s ability to surveil near-Earth objects (NEOs) is woefully incomplete.

Any space rock with an orbit that takes it within 125 million miles of the sun is considered an NEO. But Johnson said in July that NASA thinks “we’ve only found about a third of the population of asteroids that are out there that could represent an impact hazard to the Earth”.

Of course, humanity hopes to avoid a surprise like the dinosaurs got 65 million years ago, when a 10km-wide asteroid crashed into the Earth. But in recent years, scientists have missed plenty of large, dangerous objects that came close.

Comet Neowise, a 5km-wide chunk of space ice, passed with 64 million miles of Earth in July. Nobody knew that comet existed until a NASA space telescope discovered it approaching four months prior.

In 2013, a meteor about 19.81m in diameter entered the atmosphere traveling 64,374km/h. It exploded over Chelyabinsk, Russia, without warning, sending out a shock wave that broke windows and damaged buildings across the region. More than 1,400 people were injured.

And in 2019, a 130.15m-wide, “city-killer” asteroid flew within 72,420km of Earth. NASA had almost no warning about it.

That’s because currently, the only way scientists can track an NEO is by pointing one of Earth’s limited number of powerful telescopes in the right direction at the right time.

To address that problem, NASA announced two years ago that it would launch a new space telescope dedicated to watching for hazardous asteroids. That telescope, named the Near-Earth Object Surveillance Mission, along with the European Space Agency’s newly launched Test-Bed Telescope and the Flyeye Telescope that’s being built in Italy, should eventually bolster the number of NEOs we can track.

NASA is testing ways to stymie an asteroid

NASA has investigated the options scientists would have if they were to find a dangerous asteroid on a collision course with Earth. These include detonating an explosive device near the space rock, as the exercise participants suggested, or firing lasers that could heat up and vaporize the asteroid enough to change its path.

Another possibility is sending a spacecraft up to slam into an oncoming asteroid, thereby knocking it off its trajectory. This is the strategy NASA is most serious about.

Later this year, the agency is scheduled to launch a test of such a technology. The Double Asteroid Redirection Test (DART) will send a spacecraft to the asteroid Dimorphos and purposefully hit it in the fall of 2022.

NASA hopes that collision will change Dimorphos’s orbit. While that asteroid isn’t a threat to Earth, the mission could prove that redirecting an asteroid is possible with enough lead time.

NASA mô phỏng tiểu hành tinh 105 m đâm vào Trái Đất

Cơ quan Hàng không Vũ trụ Mỹ (NASA) tổ chức hoạt động diễn tập mô phỏng một tiểu hành tinh chuẩn bị đâm vào Trái Đất, phá hủy khu vực rộng 150 km.

Tình huống va chạm giả tưởng này kéo dài suốt từ hôm 26/4 đến hết tuần, tại Hội nghị phòng thủ hành tinh lần thứ 7 của Viện Hàn lâm Hàng không vũ trụ Quốc tế. Hoạt động diễn tập diễn ra dưới sự chỉ đạo của Trung tâm Nghiên cứu Vật thể gần Trái Đất (CNEOS) của NASA. Trong tuần cuối tháng 4, CNEOS cung cấp thông tin mới mỗi ngày cho những chuyên gia tham dự hội nghị.

Tình huống bắt đầu với giả định một tiểu hành tinh được phát hiện hôm 19/4 với tên gọi 2021 PDC. Sử dụng hệ thống theo dõi va chạm, các nhà khoa học nhận định vụ va chạm sẽ xảy ra trong vòng 6 tháng, với khả năng xảy ra là 1/2.500.

Hôm 26/4, nguy cơ va chạm được tính toán lại là 5%. Tiểu hành tinh giả tưởng 2021 PDC có đường kính ước tính từ 35 đến 700 m. Nhóm chuyên gia cũng dự đoán một số tác động có thể xảy ra, từ vụ nổ trong không trung không gây thiệt hại nghiêm trọng tới sự kiện tuyệt chủng hàng loạt.

Ngày hôm sau, tình huống được đẩy nhanh tới tháng 5/2021. Lúc này, giới chuyên gia tính toán tiểu hành tinh chắc chắn đâm vào Trái Đất và nơi xảy ra va chạm nằm ở châu Âu hoặc Bắc Phi. Tuy nhiên, họ biết rất ít về kích thước chính xác của vật thể. CNEOS đề xuất vài giải pháp bao gồm phóng một quả bom nguyên tử vào tiểu hành tinh. Do việc làm chệch hướng tiểu hành tinh không khả thi, họ cân nhắc gián đoạn đường bay của vật thể bằng thiết bị nổ hạt nhân.

Trong ngày thứ 3 của hội nghị, mốc thời gian của tình huống được ấn định vào cuối tháng 6. Sử dụng kết quả đo từ kính viễn vọng, các nhà nghiên cứu tính toán đường kính 2021 PDC là 160 m và khu vực xảy ra va chạm được giới hạn ở trung tâm châu Âu.

Vào ngày cuối cùng của hội nghị, CNEOS kết luận tiểu hành tinh giả tưởng có kích thước khoảng 105 m. Nó sẽ rơi ở Cộng hòa Czech gần biên giới với Đức và Áo, với năng lượng bằng 40.000.000 tấn thuốc nổ TNT, tương đương một quả bom nguyên tử cỡ lớn. Tiểu hành tinh sẽ phá hủy khu vực rộng 150 km. Thông qua các bước, nhà chức trách tiếp nhận phản hồi dựa theo dữ liệu mới nhất mà họ công bố, giúp đảm bảo mỗi bộ phận phối hợp nhuần nhuyễn để xử lý thảm họa.

Trên thực tế, NASA đang lên kế hoạch phóng một tàu vũ trụ để làm chệch hướng tiểu hành tinh, giúp điều chỉnh quỹ đạo của nó nếu vật thể bay về phía Trái Đất. Nhiệm vụ DART sẽ được phóng vào cuối năm 2021 hoặc đầu năm 2022. Tàu vũ trụ sẽ bay tới hệ tiểu hành tinh nhị phân Didymos và đâm vào một tiểu hành tinh ở vận tốc 7 km/s, giúp đo đường bay của nó thay đổi như thế nào trong không gian.

Asteroid simulation by NASA and ESA confirms Earth not prepared for major strike NASA: Expert says ‘little can be done’ about large asteroids While there are no known significant asteroids on a collision course with Earth, an asteroid impact is considered inevitable in our planet’s future. The potential impact could still be millions of years away, but NASA and ESA have been working now to prepare for the inevitable. Over the course of the week commencing April 26, members of NASA’s Planetary Defense Coordination Office (PDCO) and the ESA participated in a “tabletop exercise” to see how an asteroid strike would play out. The participants of the event had no idea about the asteroid and were given cues by external sources throughout the week, with each day meant to represent a month. The event, led by NASA’s Jet Propulsion Laboratory’s Center for Near Earth Object Studies (CNEOS), determined a hypothetical large asteroid was on its way to Earth. The hypothetical asteroid was dubbed 2021 PDC and was estimated to be anywhere between 35 metres and 700 metres in size. Asteroid simulation by NASA and ESA confirms Earth not prepared for major strike (Image: GETTY) While there are no known significant asteroids on a collision course with Earth, an asteroid impact is considered inevitable (Image: GETTY) On day one of the conference, using entirely fictitious scenarios, NASA and ESA discovered there was a five percent chance it would hit Earth. The tabletop exercise then determined the asteroid would hit Earth somewhere in Europe. However, by day three of the conference, which was held entirely online, the team ‘discovered’ the asteroid to be 160 metres, give or take 80 metres either side. A collision of a space rock that size would have enough force to cause an explosion equivalent to a powerful nuclear bomb. READ MORE: Extraterrestrial particles found in Antarctica reveal impact The hypothetical asteroid was 160 metres (Image: GETTY) The ESA said: “As would be the case if a real asteroid were on collision course, the International Asteroid Warning Network (IAWN) – a network of organisations that detect, track and characterise potentially hazardous asteroids – publicly disseminated weekly updates on the impact probability as the situation progressed.” By the end of the week, experts acknowledged with certainty that the asteroid would hit between Germany and the Czech Republic. When it would hit, organisers said it would flatten an area of more than 150 kilometres. Ultimately, the team determined that if there was a detection service in place in 2014, the asteroid could have been stopped.

(Image: EXPRESS) The exercise briefing concluded: “Had a more sensitive asteroid survey such as NEOSM or Rubin Observatory (LSST) been in place in 2014, it would almost certainly have detected the scenario object, and the 7-year warning of potential impact would have opened up a host of different possible outcomes.” Detlef Koschny, Head of ESA’s Planetary Defence Office, said: “A big lesson was that we need more long-term planning on how we can spot, track and ultimately mitigate potentially dangerous asteroids. “Simply thinking in annual or bi-annual planning cycles, which is how many budgets at public institutions are set, is not good enough to address a risk that has been hundreds of millions of years in the making.” The ESA added in a statement that an asteroid strike will happen in real life. Asteroids, comets and meteors (Image: EXPRESS) The space agency said: “Finally, one thing is clear: an asteroid impact, although unlikely, is probably going to happen sooner or later – so it is best to be prepared.” Lindley Johnson, NASA’s Planetary Defense Officer, said: “Each time we participate in an exercise of this nature, we learn more about who the key players are in a disaster event, and who needs to know what information, and when. “These exercises ultimately help the planetary defence community communicate with each other and with our governments to ensure we are all coordinated should a potential impact threat be identified in the future.” if(typeof utag_data.ads.fb_pixel!=="undefined"&&utag_data.ads.fb_pixel==!0)!function(f,b,e,v,n,t,s)if(f.fbq)return;n=f.fbq=function()n.callMethod?n.callMethod.apply(n,arguments):n.queue.push(arguments);if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)(window,document,'script','https://connect.facebook.net/en_US/fbevents.js');fbq('init','568781449942811');fbq('track','PageView') Source link Orbem News #Asteroid #confirms #Earth #ESA #Major #NASA #prepared #simulation #Strike
