“You can only do something to address a threat if you know about it,” Moissl says. “So the very first step in the whole chain is observations 🔭. You need to find the #asteroids.” https://www.sciencefocus.com/space/asteroids-team-saving-earth

"If necessary, we can build a spacecraft to deflect an #asteroid ☄️ in four years" ⏳🥱 https://www.mundoamerica.com/entertainment/2025/02/24/67bc4638fc6c83360e8b4591.html

Meet the team tasked with saving Earth from world-ending asteroids | BBC Science Focus Magazine

When asteroids come tearing towards Earth, we rely on NASA's planetary defence team to save us from disaster.

🧲☄️ Researchers at the University of #Colorado #Boulder suggest that powerful magnets could provide a way to redirect #asteroids without touching them.

By using a #spacecraft to generate a magnetic field, scientists could nudge metallic #space #rocks into safer orbits. The method offers a more controlled alternative to physically crashing probes into asteroids.

We could protect Earth from dangerous asteroids using a huge magnet

A new spacecraft concept called NOVA could keep asteroids from hitting our planet by using a huge magnet to gradually pull them apart while shifting their trajectories

Who alerts the world when an asteroid could hit Earth? This woman

Aarti Holla-Maini, of the UN’s Office for Outer Space Affairs, is primed and ready should a planetary strike occur – and just over 12 months ago, she thought it might

Was Life Seeded from Space? ‘Complete Set’ of DNA Ingredients Discovered on Asteroid

“Organic molecules delivered from extraterrestrial materials may have played a key role in supplying building blocks for life on Earth,” said one scientist.

Un bel mashup Starcom+Asteroids. Io mi sono divertito come un matto sia a disegnarlo (matita su carta) che a colorarlo (in digitale con Clip Studio Paint) 💫

A cool Starcom+Asteroids mashup. I had a blast both drawing it (pencil on paper) and coloring it (digitally with Clip Studio Paint).

@PeteTucker Whether to send people to #space in large numbers is a different question than whether to go to space at all. The answer to the latter is yes. Beyond the plentiful scientific reasons, there are good commercial reasons — rare and valuable resources. Consider #asteroids for example. Carbonaceous Chondrite asteroids contain carbon-based pre-biotic molecules that are extremely valuable in pharmaceutical discovery and various manufacturing processes. The metallic asteroids include large deposits of valuable metals - gold, platinum, titanium. Thousands of “near Earth objects” #NEO are more accessible than any planetary surface. Mining these resources can be done entirely with robotic automation. Thinking about space needs to stretch our imagination more, because we’ll never do things that we do not imagine.

RE: https://mstdn.social/@TechCrunch/116205018327360404

A reliable technology for returning payloads to Earth from #space 🌌 is a necessity for several futuristic business models — testing new materials in orbit, manufacturing #pharmaceuticals 💊 or high-end #electronics in microgravity, or harvesting resources like metals from #asteroids.

Making satellites reusable ♻️ : "If you want to update a payload component every year, instead of having to build new #satellites 🛰️ and keep those old ones up in space, you can bring them down and go back"
