International cooperation on #asteroid detection and deflection continues to grow, and 2029 designated as the International Year of Asteroid Awareness and Planetary Defence, highlighted by the close (but safe) approach of asteroid #Apophis. #PlanetaryDefence

Understanding asteroids is key to protecting our planet. 🌍 This #AsteroidDay, we're celebrating the team behind our work on @esa's #HeraMission and #RAMSES, advancing #PlanetaryDefence through innovation, expertise and dedication.

🌍☄️ Happy Asteroid Day! ☄️🌍 Every year on 30 June, we come together to raise awareness of asteroid impact risks and celebrate global efforts in planetary defence and space science. From the Tunguska event of 1908 to ESA’s groundbreaking Hera mission, the story of asteroids is one of cosmic power, scientific curiosity, and international cooperation. 📖 Read our article to explore the history, milestones, and future of asteroid research – including key impact events and what’s ahead for space missions: 🔗 bis-space.com/asteroid-day-2… #AsteroidDay #PlanetaryDefence @esa #RamsesMission #HeraMission #SpaceSituationalAwareness #SpaceExploration #Chelyabinsk #Tunguska #SpaceSafety

☄️ Happy Asteroid Day! 🌍 Did you know there are millions of asteroids orbiting our Sun, with more than 1.4 million discovered so far? While Hollywood might have us imagining giant space rocks heading straight for Earth every other week, the reality is much more fascinating. Asteroid Day, celebrated every year on 30 June, is a global campaign dedicated to raising awareness about asteroids, how scientists monitor them, and why planetary defence is so important. Asteroids are like time capsules from the birth of our Solar System, preserving clues about how the planets, including Earth, formed more than 4.5 billion years ago. By studying them, astronomers can unlock the history of our cosmic neighbourhood and even prepare for the rare chance that one might pose a future risk. The good news? Astronomers around the world are constantly searching the skies for near-Earth asteroids. Thanks to powerful telescopes and international collaboration, we've discovered and tracked the vast majority of large asteroids that could threaten our planet, and none are on a collision course with Earth in the foreseeable future. So today, take a moment to look up, appreciate the incredible work being done to protect our planet, and celebrate these ancient rocky wanderers that continue to teach us about the origins of our Solar System. ☄️ What's your favourite asteroid? Is it the metallic world Psyche, the rubble-pile asteroid Bennu, or perhaps Vesta, one of the largest objects in the asteroid belt?

🚀 Major Asteroid Missions: Building Earth's Planetary Defence ☄️🌍 On #InternationalAsteroidDay, these landmark missions showcase how science is preparing humanity for potential asteroid threats. 🛰️ NASA DART (2022): First successful planetary defence test, altering the orbit of Dimorphos through kinetic impact. 🪨 NASA OSIRIS-REx (2023): Returned samples from asteroid Bennu, revealing clues about the Solar System's origins and improving impact-risk assessment. 🛰️ ESA Hera (2026): Will study DART's impact on the Didymos–Dimorphos system to validate future asteroid deflection techniques. 📌 UPSC Value Add: Together, these missions represent the Planetary Defence Cycle: Discover → Characterise → Deflect → Validate. #PlanetaryDefence #Asteroids #NASA #ESA #DART #OSIRISREx #Hera #UPSC #SpaceScience

☄️ International Asteroid Day 2026, 30th June | Types of Asteroids (Beyond the Basics) | UPSC Did you know asteroid classification goes beyond just composition? Here's what every UPSC aspirant should know: 🔹 C-type (Carbonaceous): • Rich in water-bearing minerals and organic compounds • Found mainly in the outer Asteroid Belt • Scientists believe they preserve the most primitive material from the early Solar System. 🔹 S-type (Silicaceous): • Dominant in the inner Asteroid Belt • Higher reflectivity (albedo) than C-types • Frequently represented among meteorites that reach Earth. 🔹 M-type (Metallic): • Thought to be fragments of the metallic cores of ancient protoplanets • Some may contain significant quantities of iron, nickel, and platinum-group metals • Future targets for space resource exploration. #InternationalAsteroidDay #UPSC #ScienceAndTechnology #PlanetaryDefence #Asteroids #SpaceScience #CurrentAffairs #Prelims2027

DD News ke dwara share ki gayi ye post sach me bohot hi zyada informative aur eye-opening hai. World Asteroid Day par science, research aur global collaboration ki baat karna dikhata hai ki hum insaan ab sirf apni dharti tak seemit nahi hain, balki aane wale bhavishya ke bade khatron ko lekar bhi utne hi aware ho rahe hain. ​Sach kahun toh, planetary defence aur space science sirf scientists ka vishay nahi hai, balki ye poori manav jati (humanity) ki suraksha se juda mamla hai. Jaise hum apne daily life me chote-mote frauds aur nuksaan se bachne ke liye rules aur awareness ka sahara lete hain, thik waise hi bade level par poori prithvi ko safe rakhne ke liye is tarah ki scientific discoveries aur deep research sabse badi dhaal hain. ​Ek zimmedar nagrik ke taur par mujhe lagta hai ki aane wali nayi peedhi (next generation) me space aur science ko lekar curiosity jagana bohot zaroori hai. Jab tak hamare youth me scientific approach aur sawaal poochne ki aadat nahi hogi, tab tak hum aage nahi badh sakte. Is shandar reminder ke liye @DDNewslive ka shukriya, ye hamari soch ko aur bada banane me madad karta hai. ​#WorldAsteroidDay2026 #SpaceScience #ScienceForAll #PlanetaryDefence #FutureReady #Innovation

Greetings and best wishes on International Asteroid Day 2026.

BIS West Midlands Branch: Flying to a Potentially Hazardous Object – A Mission of Gravity Date: 20 September 2025 Time: 2:00 pm - 3:15 pm BST Location: Online via Zoom Register to attend 👉 tinyurl.com/53vwryxn How might humanity send a mission to explore or even deflect a potentially hazardous object (PHO)? A PHO is a celestial body, usually an asteroid, which regularly intersects Earth’s orbit and, depending on size, has the potential to cause a few minor casualties (such as Chelyabinsk), or can even erase entire species (such as Chicxulub which wiped out the dinosaurs). Speakers: Adam Hibberd and Marshall Eubanks  Adam Hibberd is the principal astrodynamicist behind Project Lyra (the investigation of missions to catch the interstellar object ‘Oumuamua), and who is also creator of ‘Optimum Interplanetary Trajectory Software’. He is joined by the talented and passionate scientist, with a prestigious history in the space sector, Marshall Eubanks, owner of Space Initiatives Inc., to present a talk concerning their recent research into a mission to the infamous PHO designated 2024 YR4. #asteroids #NEO #PlanetaryDefence 🌍🛡️☄️

🚨 3rd interstellar visitor spotted! At 10:15 UTC on 2 July, our Australian sensor captured A11pl3Z - only the 3rd interstellar object ever seen. 514M km from Earth 🌌 #Spaceflux #A11pl3Z #PlanetaryDefence

NASA Alert! 🚨 Asteroid 2025 MK90, roughly airplane-sized, is set to zoom past Earth today at over 21,000 mph. While there’s no danger, ISRO & NASA are closely tracking it as part of global planetary defence efforts. Here’s why even harmless space rocks matter.
