Our @HouseScience hearing highlighted the stakes: Planetary defense is about preparation and prevention. NASA’s progress is encouraging, but more work is needed to find and deflect hazardous asteroids. NEO Surveyor will be a game-changer.

Thanks to #PlanetaryDefense efforts at NASA and across the globe, we've discovered over 11,000 near-Earth #asteroids larger than 140 meters in size. It's estimated there are ~14,000 left to find. 🔭 Learn more about Planetary Defense NASA:

How many space rocks are in Earth's cosmic neighborhood? More than you might think, and we’re keeping tabs! NASA’s Planetary Defense team is tracking them because the first step to staying safe is knowing what’s out there.

Before we can defend our planet from a potential asteroid impact, we need to find the potential impactors! Our planetary defense network has now found more than 40,000 near-Earth objects and ruled out any known impact within the next hundred years.

Just pushed another update (in the same month!) to our fully on-chain factory sim: - Mine asteroids to (really) get titanium - Build planetary defenses - Raid others to steal resources - New units and buildings for PvP - Game objectives and space pirates .. and lots more! /1

Astronomers at Harvard University recently announced the discovery of a new asteroid near Earth, identified on January 2, 2025. However, they later realized that the object was actually Elon Musk's Tesla Roadster, which was launched into space by SpaceX in February 2018. The car had drifted past Mars into the asteroid belt and swung back to within 150,000 miles of Earth. The initial misidentification highlights concerns among astronomers about the increasing number of untracked space objects, which can complicate efforts to detect and study potentially hazardous asteroids.

📷 An international team of scientists have used data collected by the NASA/ESA/CSA James #Webb Space Telescope to detect a carbon molecule, methyl cation. 🧬This discovery may teach us more about how life developed on Earth and how it could potentially develop elsewhere in our Universe...

US to Iranian Regime: “Give up your nuclear program, give up the enriched uranium, give up your ballistic missile program, stop funding proxies and terrorism, stop killing your citizens, and just be a normal decent country” Iranian Regime to US: “Let’s compromise. Stop the war. Give us a lot of money. Release all our frozen assets. Commit to never attacking us again. And we have full control of the Strait of Hormuz. In return, we keep our nuclear program, we keep the uranium, we keep our missile program, we keep funding our proxies, we keep killing our people… oh, and death to Israel and death to America” US: “We think you misunderstood. You cannot have nukes. No uranium. You must stop killing civilians. You must stop funding proxies, and you must open the Strait of Hormuz” Iranian Regime: “Ah, now we understand. Ok then, let’s negotiate. Stop the war. Give us a lot of money. Release all our frozen assets. Commit to never attacking us again. And we have full control of the Strait of Hormuz. In return, we keep our nuclear program, we keep the uranium, we keep our missile program, we keep funding our proxies, we keep killing our people… oh, and death to Israel and death to America” US: “Listen, you either agree to our terms or we will have no choice but to strike again and all hell will break loose. You have 3 days.” Iranian Regime: “Fine. You’re twisting our arm. We know you won’t attack and if you do we will burn the whole region and humiliate you. But… we are willing to negotiate in good faith. So… Stop the war. Give us a lot of money. Release all our frozen assets. Commit to never attacking us again. And we have full control of the Strait of Hormuz. In return, we keep our nuclear program, we keep the uranium, we keep our missile program, we keep funding our proxies, we keep killing our people… oh, and death to Israel and death to America” US: “Enough. We are giving you one more last chance. Agree to our terms or else. No more chances. You have one week.” Iranian Regime: “We are prepared to negotiate and meet you half way. It has to be fair. So… Stop the war. Give us a lot of money. Release all our frozen assets. Commit to never attacking us again. And we have full control of the Strait of Hormuz. In return, we keep our nuclear program, we keep the uranium, we keep our missile program, we keep funding our proxies, we keep killing our people… oh, and death to Israel and death to America” US: “Stop playing games. This is serious. We will not give you any more chances. You have two weeks or all hell will break loose” Iranian Regime: “We accept to agree to negotiate where we can discuss your terms over the next 30 days. But… Stop the war. Give us a lot of money. Release all our frozen assets. Commit to never attacking us again. And we have full control of the Strait of Hormuz. In return, we keep our nuclear program, we keep the uranium, we keep our missile program, we keep funding our proxies, we keep killing our people… oh, and death to Israel and death to America” And round and round and round we go.
