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

We're just circling back on some things... In the coming months, our planetary exploration spacecraft will be making close approaches to the Sun, Mars, Jupiter, an asteroid, and more.

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...
