The space agency has been working tirelessly to identify dangers that Earth face from space, and has said that it has found 10 new asteroids of meteors which it believes could harm life on Earth.
The discovery was made by NASA’s asteroid detecting mission – Near-Earth Object Wide-field Infrared Survey Explorer or NEOWISE.
Amy Mainzer, NEOWISE principal investigator from NASA’s Jet Propulsion Laboratory in Pasadena, California, said: “NEOWISE is not only discovering previously uncharted asteroids and comets, but it is providing excellent data on many of those already in our catalog.
“It is also proving to be an invaluable tool in in the refining and perfecting of techniques for near-Earth object discovery and characterisation by a space-based infrared observatory.”
On top of the 10 “potentially hazardous” objects, Nasa says that they have identified 97 other space rocks and seen an unexplained spike in comet activity.
Emily Kramer, a NASA Postdoctoral Program Fellow at JPL and lead author of paper on the NEOWISE study stated: "Comets that have abrupt outbursts are not commonly found, but this may be due more to the sudden nature of the activity rather than their inherent rarity.
"It is great for astronomers to view and collect cometary data when they find an outburst, but since the activity is so short-lived, we may simply miss them most of the time.”
The findings come shortly after a group of Czech scientists warned fragments of asteroids which could wipe out entire countries are hidden in the Taurids meteor shower.
The startling finding means that experts may not be able to spot the massive space rock hidden in the annual Taurids meteor shower until it is too late.
According to the group of researchers, one of the fragments could hit Earth in 2022, 2025, 2032 or 2039 during the annual meteor shower.
"Impact hazard increases significantly when the Earth encounters the Taurid new branch"
Experts from the Astronomical Institute of the Czech Academy of Science said: “Since asteroids of sizes of tens to hundreds meters pose a treat to the ground even if they are intrinsically weak, impact hazard increases significantly when the Earth encounters the Taurid new branch every few years.
“Further studies leading to better description of this real source of potentially hazardous objects, which can be large enough to cause significant regional or even continental damage on the Earth, are therefore extremely important.”
NASA and FEMA Prepare For Asteroid Impact With Emergency Planning Exercise
NASA scientists and crisis management specialists have held high-level training exercises to prepare for an asteroid strike on Earth.Senior officials said the exercise simulated an asteroid impact on Los Angeles on September 20 2020. They propose a scenario in which object 300-800 feet wide approaches.The exercise gave no time to launch an asteroid deflection mission and left emergency managers faced with the mass evacuation of more than 18 million people from Greater LA.The exercise provided a forum for the planetary science community to show how it would collect, analyse and share data about an asteroid colliding with Earth. Emergency managers discussed how the data would be used to consider some of the unique challenges an asteroid impact would present – for preparedness, response and public warning.
It’s a scary scenario: an asteroid headed for Earth, just four years away from slamming into our home planet. It may be too short a span to plan an asteroid-deflection mission, but it’s long enough to present very different challenges from those of a more typical crisis, like a hurricane or earthquake.
NASA and the Federal Emergency Management Agency (FEMA) came together Oct. 25 to plan a response to such a hypothetical event. In a “tabletop exercise,” a kind of ongoing simulation, the two agencies tested how they would work together to evaluate such a threat, prevent panic and protect as many people as possible from the deadly collision.
“It’s not a matter of if, but when, we will deal with such a situation,” Thomas Zurbuchen, NASA’s Science Mission Directorate’s new associate administrator, said in a statement. “But unlike any other time in our history, we now have the ability to respond to an impact threat through continued observations, predictions, response planning and mitigation.”
The exercise, held in El Segundo, California, brought together representatives from NASA, FEMA, NASA’s Jet Propulsion Laboratory (JPL), the Department of Energy’s national laboratories, the Air Force and the California Governor’s Office of Emergency Services, JPL officials said in the statement.
It was the third such exercise; previous ones had allowed for a deflection mission, but in this simulation, there was too little time for that type of response.
“It is critical to exercise these kinds of low-probability but high-consequence disaster scenarios,” FEMA Administrator Craig Fugate said in the statement. “By working through our emergency response plans now, we will be better prepared if and when we need to respond to such an event.”
The asteroid in this test scenario appeared to be between 300 and 800 feet (100 to 250 meters) long in the first simulated measurements the participants were given. At first, the probability of a 2020 impact was only 2 percent, but as the group continued to simulate tracking it over time and the fictional months went by, the impact probability rose to 65 percent — and then 100 percent, in May 2017. By November of that year, in the scenario, they found that it would hit across Southern California or nearby in the Pacific Ocean.
The research laboratories’ scientists calculated the impact’s footprint, the population that would be displaced, the effect on infrastructure and other data that would slowly become clear over such an asteroid’s approach. That gave the participants the information they needed to plan for an evacuation process, and decide how to convey necessary information to the public in the most effective way over the course of the asteroid’s approach (plus debunk dangerous misinformation and rumors).
WARNING: NASA Discovers 10 ‘Potentially Hazardous’Asteroids Close to Earth-NASA and FEMA Prepare For Asteroid Impacthttps://www.newsprepper.com/asteroid-warning-nasa-discovers-10-potentially-hazardousasteroids-close-earth-nasa-fema-prepare-asteroid-impact/

“The high degree of initial uncertainty, coupled with the relatively long impact warning time, made this scenario unique and especially challenging for emergency managers,” Leviticus A. Lewis, chief of FEMA’s National Response Coordination Branch, said in the statement. “It’s quite different from preparing for an event with a much shorter timeline, such as a hurricane.”
NASA’s Planetary Defense Coordination Office, established in January, supervises NASA’s efforts to track asteroids and other approaching near-Earth objects (NEOs) and coordinates its interactions with the other U.S. agencies that would deal with a potential impact and decide whether to try a deflection mission or coordinate an emergency response, as in this exercise. Europe has a similar NEO Coordination Centre in Italy.
“These exercises are invaluable for those of us in the asteroid science community responsible for engaging with FEMA on this natural hazard,” NASA Planetary Defense Officer Lindley Johnson said in the statement. “We receive valuable feedback from emergency managers at these exercises about what information is critical for their decision making, and we take that into account when we exercise how we would provide information to FEMA about a predicted impact.”
Although deflection wasn’t an option for this training scenario, there is research into that area. For example, NASA’s Asteroid Redirect Mission, which recently finished its first planning stages, is largely a sample-collection mission, to pull a boulder off an asteroid’s side — but it is also slated to test out pulling the asteroid’s orbit slightly off course using the spacecraft and sample’s gravitational pull.
Philip Lubin, an astrophysicist at the University of California, Santa Barbara whose laser propulsion system has been incorporated into the Breakthrough Starshot program to send a probe to neighbor star system Alpha Centauri, originally intended the system to zap and deflect incoming asteroids.
