Spaceflight 🚀#HelioLinc3D spotted an #asteroid ☄️ that similar surveys had failed to see. It was specifically designed for the @VRubinObs in #Chile 🇨🇱. The #observatory’s huge mirror 📡, massive camera and expansive eye will see 👁️ pretty much everything in the night sky 🌌 in unprecedented detail https://www.nytimes.com/2023/08/05/science/space-asteroids-rubin-heliolinc3d.html
In 📆 2018, #StephenHawking considered an #asteroid ☄️ collision to be the biggest threat to the #planet. The #US National Science and Technology Council warned that America is unprepared for an asteroid impact 💥 event https://en.wikipedia.org/wiki/Asteroid_impact_prediction
“Our goal is that by 📆 2030, #Europe 🇪🇺 can provide early warning for hazardous #asteroids larger than 40 m in size, about three weeks before any impact” https://www.esa.int/Space_Safety/Flyeye_ESA_s_bug-eyed_asteroid_hunter

“The most glaring mistake is the #government cover-up… just completely bogus.” And a #meteorite that struck southwest #Ontario in November illustrated that a cover-up couldn’t be further from the truth when actual Earth-pummeling #asteroids ☄️ are found. https://www.sciencefocus.com/news/you-help-protect-earth-asteroid

Asteroid discoveries from Earth -Asteroid Institute + Google April 30, 2024
We simply didn't notice 🙈 until recently 😨 https://ourworldindata.org/data-insights/over-33000-near-earth-asteroids-have-been-detected-since-1990
Over 40,000 near-Earth asteroids have been detected since 1990
Since the late 20th century, astronomers and space agencies have taken steps to monitor the threat of large asteroids passing near Earth. They set up international efforts to find these objects early, track their paths, and learn more about what they’re made of, so we’d have the best chance of spotting a real collision risk in time.
Only eight #asteroids ☄️ have ever been detected before impact 💥 with #Earth’s atmosphere. The first of these discoveries took place in 📆 2008, and four were detected in just the last two years https://www.esa.int/Space_Safety/Planetary_Defence/Asteroid_2024_BX1_spotted_three_hours_before_impact
#Asteroid danger explained : "The main challenge stems from the population of middle-size objects, ranging from tens to hundreds of metres in diameter. There are a lot of these asteroids, and most have not been spotted yet." https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
@VRubinObs 🔭 Today, #astronomers are aware of only about 40 percent 📊 of potentially hazardous #asteroids ☄️ - close-flying objects that are large enough to cause continent-wide destruction if they were to impact 💥 Earth. "The idea is, if there is an object like that, we want to find it while it’s maybe 40 or 50 years out, because that gives us enough time to figure out how we’re going to deflect it.” https://www.smithsonianmag.com/science-nature/this-revolutionary-new-observatory-will-locate-threatening-asteroids-and-millions-of-galaxies-180984514/

#Asteroid ☄️ #2024RW1 burned 🔥 up in the atmosphere over the South Pacific, creating a spectacular bright flash in the sky over the #Philippines just hours ⏱️ after first being detected. It was expected to hit at a speed of 17.6 km/s, or 63,360 km/h https://www.newscientist.com/article/2446397-a-small-asteroid-hit-earth-and-burned-up-over-the-philippines/
