Earth’s orbit is getting crowded. Tens of thousands of objects circle the planet. At orbital speeds, even a marble-sized object can destroy a satellite on impact. Teams on the ground track debris and maneuver satellites to avoid collisions.

There are more than 15,000 satellites orbiting the Earth by the end of 2025 already. A space satellite is launched into orbit using a powerful rocket that lifts it through Earth’s atmosphere at speeds over 17,500 miles per hour (28,000 km/h). Once it reaches the right altitude and velocity, the rocket releases the satellite, allowing it to circle Earth due to the balance between gravity pulling it down and its forward speed carrying it around the planet. Satellites are used for communication, GPS, weather tracking, military operations, and scientific research, silently orbiting hundreds or even thousands of miles above us.

3D Orbital satellite tracking is now live. 🌐📷 We’ve rendered real-time satellite positions into true 3D orbital space across the OSIRIS globe, so you can clearly see the three main regimes that dominate Earth’s skies: • LEO (Low Earth Orbit) — the dense, fast-moving shell closest to Earth • HEO (Highly Elliptical Orbit) — the elongated paths that spend long periods over high latitudes • GEO (Geostationary Orbit) — the fixed equatorial belt where satellites appear motionless above one point on the ground. Track LEO, HEO, and GEO from orbital height all the way down to street level. Terminal: Repo: solana:2nZNHm3Lr9umG3DVrzYwHgktwkuKuJRXqqRqs3ewpump

SpaceX now has over 10,000 Starlink satellites in orbit (and growing), providing internet data service to every corner of the earth. Even ships at sea or aircraft in the sky can receive high speed internet service. Over 2/3 of the active satellites in orbit are Starlink now. And it won't create any long term trash in orbit. The orbits are so low (480 km to 550 km) that even if SpaceX were to lose control of one, the small satellites will run out of fuel within 5 years. Then they get dragged back into the atmosphere and burn up. Every satellite is in a lane to avoid other Starlink satellites. They all are connected to a collusion avoidance system and can make small course adjustments if needed. Starlink can provide high speed internet anywhere on the planet without having to bury expensive fiber cables underground or undersea. All you need is a small dish which scans the sky for the closest satellite to provide internet connectivity.

BREAKING🚨: A mysterious object appears near the Moon’s surface, creating a moment that looks unusual and difficult to explain at first. The bright lunar background makes even small moving objects clearly visible. It may look like the object is flying very close to the Moon, almost touching its surface. But in reality, it is often much closer to Earth, and this is just a result of alignment and perspective. Objects like satellites, meteoroids, or space debris can pass in front of the Moon, appearing as dark moving shapes for a few seconds.

High-Altitude Nuclear Explosion (HANE) in LEO: A Self-Destructive Cascade A Senior Defense Fellow at the American Foreign Policy Council presents a vivid simulation to the U.S. Space Force, exposing the catastrophic fallout of a LEO nuclear burst on orbital infrastructure: • Immediate Impact: The prompt radiation from a High-Altitude Nuclear Explosion (HANE) instantly destroys roughly 20% of all active LEO satellites. • Artificial Radiation Belt: Within 12 hours, a uniform radiation belt forms, exposing passing spacecraft to persistent, destructive doses. • Total LEO Blackout: Within 2 to 3 weeks, 100% of satellites in Low Earth Orbit are rendered non-operational. • Kessler Cascade Triggered: Dead satellites lose collision-avoidance capability, sparking orbital impacts. The dispersing debris drives secondary collisions, threatening a full Kessler Syndrome. • Mega-Constellation Hazard: High-density debris concentrates around the 550 km altitude shell—directly threatening LEO mega-constellations like Starlink. A HANE strike is an indiscriminate weapon of mass destruction that permanently denies orbital access to all spacefaring nations.source:

SpaceX now operates the largest satellite constellation in Earth orbit Starlink today: • ~65–70% of all active satellites around Earth • ~9,500 active satellites in orbit • ~8,500+ fully operational, delivering real broadband worldwide • Speeds: 200–400 Mbps typical with ~30 ms latency • Tonight: Falcon 9 adds 29 more satellites And this is just the beginning The FCC approved 7,500 additional Gen2 satellites, bringing the total to 15,000 This means better global coverage, higher speeds, and support for direct-to-cell connectivity From remote villages to oceans and skies, Starlink is reshaping global connectivity at a scale never seen before SpaceX is building planet-scale infrastructure that will accelerate human progress on Earth like never before

Several videos claiming to show some kind of object and/or objects burning up while entering the Earth’s atmosphere tonight over Northern Kazakhstan have begun circulating on X, with evidence suggesting that it was likely either a satellite or space debris, not, as some have suggested, the failed launch of an RS-26 “Oreshnik” Intermediate-Range Ballistic Missile by Russia against Ukraine.

Twenty five to thirty thousand years ago a comet of extraordinary scale - with a nucleus estimated at 50 to 60 miles in diameter, possibly larger - was captured into a sub-Jovian orbit, placing it on a trajectory through the inner solar system between the sun and Jupiter. What followed was a process Randall describes as hierarchical breakup - the comet progressively fragmenting over thousands of years into ever smaller cometary nuclei, each successive breakup producing a new generation of debris that spread along the orbital path. The end product of that long fragmentation process is the Taurid meteor stream - the same stream that Earth passes through twice annually and that researchers including Randall have connected to the Younger Dryas impact event. The Taurids are not simply a meteor shower. They are the debris field of one of the largest cometary bodies to enter the inner solar system in human prehistory - a 60 mile wide object whose progressive disintegration over tens of thousands of years seeded the orbital path with fragments ranging from dust to objects capable of causing continent-scale destruction. Randall’s argument is that understanding the origin of the Taurid stream is inseparable from understanding what struck the Earth at the Younger Dryas boundary. Spots are limited - click here to join Randall on his upcoming Finger Lakes tour!

Neil deGrasse Tyson explains the one event that could permanently destroy humanity's ability to use space "If you destroy a satellite, let's say it breaks into 10 pieces, each going orbital speed. Orbital speed is 17,000 miles an hour. That's way faster than a rifle bullet. So little pieces of satellite can be far more devastating than a high-powered rifle bullet shot into another satellite." "So these pieces scatter. If any one of them hits another satellite, breaking it into 10 pieces, you go from 1 to 10 to 100 to 1,000 within just a few orbits. 100% of the satellites can be taken out if you have enough satellites for that thresholding to take place."

Congrats to Isar Aerospace. U.S. and Chinese commercial launch companies are working on bringing rockets back from orbit to the ground. Europe is still working on getting rockets from the ground to orbit,even with just a one-ton payload.🤪

HOLY CRAP! Stephen Miller just CONFIRMED the State Dept. is revoking THOUSANDS of visas! “State Dept. has revoked tens of thousands of visas, and they're just getting STARTED on tens of thousands more...we have a new focus on denaturalization." THIS IS WHAT I VOTED FOR!
