Can high altitude cause headaches

A month after SpaceX's SN9 flew more than 6 miles (10 kilometers) high, its successor, SN10, duplicated the feat, flying high above Texas before nailing the landing -- a first for the prototype. SN10 is the third such developmental prototype of Starship, Elon Musk's next-generation rocket destined for the moon and Mars, to make a high-altitude flight since the mesmerizing flight and explosive ending of SN8 in December 2020 . SN9 flew high and then crash-landed and exploded on Feb. 2. The third try was the charm for SN10. SN10 reached its targeted altitude of 6 miles, cutting off each engine in series on the way up to throttle down and hit the desired apogee. The rocket then began an extended picturesque period of free fall -- a "belly flop" as it has come to be known -- before firing the engines back up to perform its trademark flip maneuver to make a vertical landing. After a six-minute journey, SN10 came to rest on the pad at SpaceX's facility in Boca Chica. … [Read more...] about SpaceX Starship prototype SN10 flies high, nails landing, then explodes

The SpaceX Starship rocket prototype, SN10, ignited its engines for a split second on Wednesday afternoon, but an issue with the launch procedure triggered an automatic abort. Elon Musk, SpaceX CEO, said the rocket had a "slightly conservative high thrust limit" but the team would recycle propellant and try again . The company is now planning to try again at around 2:30 p.m. PT and if you want to watch live, we've got you covered. These prototype tests have been coming extremely quickly for SpaceX's Starship program. Only weeks after its predecessor SN9 flew high and then crash-landed on Texas' Gulf Coast, SN10 will attempt to improve on that performance. Continue to check back here as we'll embed the livesteam for the next attempt. Alternatively, you can keep one eye on the SpaceX website , which begins a stream about five minutes prior to flight. SN10 and SN9 are the latest iterations of SpaceX and Elon Musk's Starship prototypes that the company has been developing in … [Read more...] about SpaceX Starship SN10 launch: How to watch rocket prototype fly today

SpaceX’s latest Starship prototype landed on Wednesday for the first time after carrying out a high-altitude test flight in Texas — but exploded minutes later on its landing pad. The rocket, an early test version called SN10, demonstrated a few complex dances in mid-air before clinching a soft touch down, aiming to nail a key milestone in Elon Musk’s campaign to build a fully reusable rocket system. After aborting an initial launch attempt earlier in the day, the prototype lifted off at 6:14pm ET and soared 6 miles above SpaceX’s Boca Chica, Texas facilities. Unlike the last two tests with SN8 and SN9, which launched successfully but exploded on their landing attempts, SN10 stuck a lopsided landing on a slab of concrete not far from its launchpad, appearing to survive its daring landing maneuver for a few moments before being consumed in a fireball. The launch test’s main objective was to demonstrate the computer-controlled movements of the rocket’s four aerodynamic flaps that … [Read more...] about SpaceX lands Starship prototype for the first time — and then it blows up

Virgin Galactic's experimental commercial spaceflight vehicle crashed after experiencing an "in-flight anomaly" during a test flight on Friday. One person was killed and another was suffered serious injuries.

The Lifx Clean is a new smart lightbulb with an intriguing twist. Not only is it a fully functional color-changing lightbulb, the company also claims it is capable of disinfecting surfaces and the air around it. First announced last August, the $69.99 Lifx Clean is now shipping to preorder customers in the US, with wide availability planned this spring. Lifx has an array of scientific studies as well as its own lab tests to support its claim that the Clean is the “world’s first antibacterial, germicidal smart light.” But can the lightbulb work as well in the average home as it did in the lab? It’s no coincidence that Lifx announced the bulb in a year in which we all had to pay more attention than ever before to keeping ourselves and our homes clean. Lifx’s CEO David McLauchlan says the company started having early discussions about developing a product like the Lifx Clean last March, the same month COVID-19 was officially declared a pandemic by the World Health Organization. … [Read more...] about Lifx’s bacteria-killing smart bulb works, but here’s the small print
