Ok, I had to go back and look but I'm laughing on this one:Ah, I see where I made my mistake. RanulfC started that line of thought. (I'd blocked him because I got tired of getting spammed by his walls of text.)
I DID warn him
this must be the second stage during deorbit maneuverA plethora of people in France and Belgium witnessed Starlink satellites* slow rise to orbit after the launch success.
Was it supposed to blow up?Completed the tests without anything blowing up this time.
SpaceX has successfully completed a round of Crew Dragon tests, which previously ended in an explosion. The space company attempted a similar set of static fire engine tests on April 20th, but it admitted a few days later that the Crew Dragon capsule it used was destroyed. It blamed the...www.engadget.com
Attempt at recovery of the fairing was abandoned with catchers returned to port as you say because of bad weather.
Very good, factual, must read article.Why is SpaceX able to do the job faster and cheaper than Boeing? Why do they keep being rewarded for lower performance? Is it company culture? You can throw a dart and hit problem Boeing projects.
A detailed government audit has revealed that NASA went out of its way to overpay Boeing for its Commercial Crew Program (CCP) astronaut launch services, making a mockery of its fixed-price contract with the company and blatantly snubbing SpaceX throughout the process. Over the last several...www.teslarati.com
Most telescopes can deal with that, says Olivier Hainaut, an astronomer at the European Southern Observatory (ESO) in Garching, Germany. Even if more companies launch megaconstellations, many astronomers might still be okay, he says. Hainaut has calculated that if 27,000 new satellites are launched, then ESO’s telescopes in Chile would lose about 0.8% of their long-exposure observing time near dusk and dawn. “Normally, we don’t do long exposures during twilight,” he says. “We are pretty sure it won’t be a problem for us.”
But an upcoming, cutting-edge telescope could be in bigger trouble. The US Large Synoptic Survey Telescope (LSST) will use an enormous camera to study dark matter and dark energy, asteroids and other astronomical phenomena. It will survey the entire visible sky at least once every three nights, starting in 2022. Because the telescope has such a wide field of view, satellites trailing across the sky could affect it substantially, says Tony Tyson, an astronomer at the University of California, Davis, and the LSST’s chief scientist.
He and his colleagues have been studying how up to 50,000 new satellites — an estimate from companies’ filings with the US government — could affect LSST observations. Full results are expected in a few weeks, but early findings suggest that the telescope could lose significant amounts of observing time to satellite trails near dusk and dawn.
I'd really like to see the weld design. A properly engineered weld should not fail before the base material so either there was a discontinuity or a miscalculation. Could've been the heat affected zone that really failed.Also, it appears that it was the weld between the top 2 rings that failed rather than a bulkhead failure.
