Starlink mission marks SpaceX’s 450th flight-proven Falcon booster launched – Spaceflight Now

Image: Adam Bernstein/Spaceflight Now Update Aug. 4, 4:30 a.m. EDT: SpaceX landed its first stage booster on its droneship. SpaceX passed another milestone in rocket reuse when it launched a Falcon 9 rocket from Cape Canaveral Space Force Station in the overnight hours of Monday, Aug. 4. The mission, dubbed Starlink 10-30, features the company’s 450th launch of a flight-proven booster. That stat is a combination of both Falcon 9 and Falcon Heavy rockets. SpaceX first reused a Falcon booster with the launch of the SES-10 satellite on March 30, 2017, using the first-stage booster with the tail number 1021. That booster first flew on SpaceX’s eighth Commercial Resupply Services mis...

Could we get quantum spookiness even without entanglement?

Light particles seem to exhibit quantum weirdness even when they aren’t entangledWLADIMIR BULGAR/SCIENCE PHOTO LIBRARY Particles that don’t seem to be entangled have earned a high score on a famous test of entanglement. The experiment could offer a fresh look at what makes the quantum world so strange. Nearly 60 years ago, physicist John Stewart Bell devised a test for whether our world is best described by quantum mechanics or by a set of more traditional theories. The key difference is quantum theory includes “non-locality”, or effects that can span any distance – even very large ones. Strikingly, all of the experiments that have implemented Bell’s test to date have affirmed our physical reality is non-local, suggesting we live in a quantum world. However, those...

NASA’s SpaceX Crew-11 Launches to International Space Station

Four crew members of NASA’s SpaceX Crew-11 mission launched at 11:43 a.m. EDT Friday from Launch Complex 39A at the agency’s Kennedy Space Center in Florida for a science expedition aboard the International Space Station. A SpaceX Falcon 9 rocket propelled the Dragon spacecraft into orbit carrying NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov. The spacecraft will dock autonomously to the space-facing port of the station’s Harmony module at approximately 3 a.m. on Saturday, Aug. 2. “Thanks to the bold leadership of President Donald J. Trump, NASA is back! The agency’s SpaceX Crew-11 mission to the space station is the first step toward our permanent presence on the Moon. NASA, in conjuncti...

NASA, SpaceX ‘thread the clouds’ to launch Crew-11 to the International Space Station – Spaceflight Now

Falcon 9 carrying Crew Dragon Endeavour, dodged storm clouds to launch a new crew to the International Space Station on Aug. 1, 2025. Image: Adam Bernstein/Spaceflight Now. Weather threatened to delay the Crew-11 mission for a second time, but the launch team was able to “thread the clouds” and a four-person crew lifted off on a journey to the International Space Station. Nine Merlin engines roared to life at 11:43 a.m. EDT (1543 UTC) and the SpaceX Falcon 9 rocket sped away through the cloudy skies above Florida’s Space Coast. Less than 10 minutes after liftoff, the Crew Dragon spacecraft, named ‘Endeavour’, flew free from the rocket’s second stage. “I have no emotions, but joy right now. That was absolutely transcendent, the ride of a lifetime,” said NASA astronaut and Crew-11 commander ...

Can Tariffs Lead to a More Circular Economy? – State of the Planet

As global trade tensions mount and countries recalibrate their economic priorities, tariffs may have the ability to play an unexpected role in the sustainability conversation. Tariffs on imports, while often viewed as controversial and protectionist weapons, could paradoxically drive the shift not only toward less production, but also toward more localized, circular and environmentally conscious systems. Whether this transformation occurs depends on the adaptability of policymakers, businesses and consumers. When interpreted through the frameworks of behavioral economics, supply and value chain theory, and circular economy principles, tariffs can transform consumption patterns and support a more sustainable global economy.
