SpaceX launches final block 1 WorldView Legion satellites for Maxar Technologies – Spaceflight Now

SpaceX’s Falcon 9 rocket as seen from Central Florida, making its ascent from Launch Complex 39A at NASA’s Kennedy Space Center. Onboard were two WorldView Legion Satellites that will be operated by Maxar Intelligence, a division of Maxar Technologies. Image: Michael Cain/Spaceflight Now Update 7:32 p.m. EST (0032 UTC): SpaceX confirmed deployment of the fifth WorldView Legion satellite. Shrouded in a layer of thick fog Tuesday evening, SpaceX launched the latest pair of WorldView Legion satellites on behalf of Maxar Intelligence, a division of Maxar Technologies. The two satellites launched into a mid-inclination Earth orbit (MEO) following separation from the Falcon 9 rocket. Liftoff of the mission, dubbed Maxar 3 by SpaceX, from Launch Complex 39A at NASA’s Kennedy Space Center happened...

Quantum-inspired algorithm could enable better weather forecasts

Simulating turbulent air flow accurately is vital for weather forecastsEUMETSAT/ESA Quantum-inspired algorithms can simulate turbulent fluid flows on a classical computer much faster than existing tools, slashing computation times from several days on a large supercomputer to just hours on a regular laptop. This could improve weather forecasts and increase the efficiency of industrial processes, say researchers. Turbulence in liquid or air involves numerous interacting eddies that quickly become so chaotically complex that precise simulation is impossible for even the most powerful computers. Quantum counterparts promise to improve matters, but currently even the most advanced machines are incapable of anything but rudimentary demonstrations. These turbulence simu...

Japan launches Michibiki 6 navigation satellite with fifth H3 rocket

HELSINKI — Japan’s flagship H3 rocket successfully launched the Michibiki 6 navigation satellite early Sunday, enhancing the country’s regional GPS capabilities.The Mitsubishi Heavy Industries (MHI) H3 rocket lifted off at 3:30 a.m. Eastern (0830 UTC) Feb. 2 from Tanegashima Space Center. Aboard was the 1,900-kilogram Michibiki 6 satellite, also known as the Quasi-Zenith Satellite System (QZS-6), for Japan’s navigation satellite system. The system aims to provide Japan with positioning, navigation and timing services, while increasing the accuracy and reliability of GPS services in the region. Michibiki 6 will be placed at 90.5 degrees East in the geostationary belt, 35,786 kilometers above the equator.The first Michibiki spacecraft for a four-satellite system was launched in 2010. ...

A new kind of hidden black hole may explain the mystery of dark energy

For as long as we have tried to figure out the nature of reality, we have grappled with the concept of empty space. Around 400 BC, when the ancient Greek philosopher Democritus conceived of small, indivisible bodies called atoms, he supposed there must also exist a void surrounding them: a featureless, unchanging vacuum in which they moved. Today, the void remains a potent idea for understanding the universe, but we have come to realise that it is anything but featureless. More than a century ago, Albert Einstein’s theory of gravity revealed that space-time is stretched and warped by the matter it contains. Later, quantum theory introduced the idea of virtual particles, which momentarily appear and disappear in a vacuum, making pure nothingness seem like an intangible...
