NASA Watches Earth’s Weight, Finds Center of Mass
5 min readPreparations for Next Moonwalk Simulations Underway (and Underwater) Water sloshing between the land and oceans shifts Earth’s center of mass relative to its geometric center. NASA scientists have developed a new technique using ultraprecise satellite tracking to estimate the displacement to within fractions of inches.NASA’s Scientific Visualization Studio Seasonal changes redistribute enough water around Earth to shift the planet’s center of mass back and forth by fractions of an inch
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago. Every link goes to the original publisher so you can read the full study or press release yourself.
