Before the international break gets into full swing, here is a look at the semifinals of the NWSL postseason and how the teams match up for two clashes on the West Coast.

A new experiment demonstrates that commercial solar farms in space could one day be possible, according to the researchers behind it. Scientists from the UK say that a satellite launched into space to test the opportunities to gather sunlight for power has shown more success than expected. The experiment showed that it was possible to make lightweight solar panels at low cost that would be able to work in space, researchers said. They sent one of those units into space and examined how it worked over a period of six years and 30,000 orbits. It was able to withstand the solar radiation and other damage of space, they said, and continue generating power. “We are very pleased that a mission designed to last one year is still working after six. These detailed data show the panels have resisted radiation and their thin-film structure has not deteriorated in the harsh thermal and vacuum conditions of space,” said Craig Underwood from the University of Surrey, “This ultra-low mass solar cell technology could lead to large, low-cost solar power stations deployed in space, bringing clean energy back to Earth – and now we have the first evidence that the technology works reliably in orbit.” The panels were made at the University of Swansea, and used a new kind of solar cell made out of cadmium telluride. That material allows for larger panels at lighter weights, which provide more power and are relatively cheap. Colleagues at the University of Surrey then built those panels into a satellite that could be delivered to space, as well as the technology to measure how they continued to perform once they were in orbit. Those measurements showed that the panels gradually became less efficient, but researchers say they nonetheless showed that the panels could eventually be commercially viable. Solar farms in space would overcome many of the problems with existing renewable infrastructure on Earth. The solar farms could allow for more space on the ground, but more notably would be able to avoid issues caused by weather and benefit from more intense sunlight than there is on the surface. Making units that are able to withstand the difficulties of space is just one of a number of challenges for solar farms in space. There would also need to be a way to get the energy back down to us, for instance – though this summer researchers were able to successfully beam power down to Earth using microwaves. A study describing the findings, ‘IAC-22-C3.3.8 Six years of spaceflight results from the AlSat-1N Thin-Film Solar Cell (TFSC) experiment’, is published in the journal Acta Astronautica.

Apple has announced a surprise event, at which it is expected to unveil new Macs. The event is unusual in a number of ways, including its much later start than Apple’s regular events: it will begin at 5pm local pacific time, or midnight in the UK. Apple events almost always begin at 10am local time, and it did not give any indication of why it had changed its time. It will also take place notably late in the year, on 30 October. Apple appeared to reference the proximity to Hallowe’en in its invitation, which used the title “Scary fast”. It will also be entirely virtual, with no in-person attendance. Apple switched to fully virtual events during the pandemic, but has since opened up physical attendance as restrictions have lifted. Unlike many recent Apple events, it is unclear what exactly the company is planning – though Apple’s website used the “Finder” icon from the Mac operating system, all but confirming a focus on its computers. Apple seems likely to introduce a new version of its iMac, which was last updated in April 2021 and is now far behind all of the rest of Apple’s line-up. It still uses Apple’s M1 chip, and the event will presumably at least bring it up to speed with the existing M2 processors. The company might unveil its first M3 processors, however. Apple’s first M2 computers arrived last summer, inside updated MacBook Air and MacBook Pro models, and so those computers could also be updated with the latest generation. Some reports have also suggested that Apple could be planning an update for its most high-end and expensive 14- and 16-inch MacBook Pro, too. Those were overhauled earlier this year, however, with the introduction of the M2 Pro and M2 Max, meaning that any new update might be less likely or could be more minor. Recent weeks brought rumours that Apple was planning to update at least some of its iPads. The rumoured launch day only brought a new Apple Pencil, however – which may mean that the iPads were delayed for the upcoming event, or may mean that Apple opted not to make any changes to the iPad and released the Apple Pencil to clear the way for its new Macs. The latest launch comes the month after Apple held another live event – at its usual time – to launch the new iPhone 15 and other products.
