Low Earth orbit, where most satellites operate, has become a whirlwind of metal shards and dead, tumbling debris.
大多数卫星运行的近地轨道已经变成了金属碎片和死去的、翻滚的碎片的旋风。

To the naked eye, the stars are diamond flecks scattered across the inner surface of a celestial sphere. Telescopes have brought depth to our vision, mapping the true distances to cosmic objects. But the universe they reveal appears utterly beyond the human scale of space and time. Even the closest stars seem infinitely remote, and reaching them a thing of science fiction, save for a few dead and dying probes drifting outward for millennia to come.

Have you ever thought, “IEEE Spectrum is terrific, but I just wish I had a way to experience even more of it, perhaps at a local science and technology museum?” Well, I am pleased to say that your very specific wish has been granted! In collaboration with the IEEE History Center and the IEEE Global Museum and the support of generous donors, Spectrum's – Chip Hall of Fame has been adapted into a traveling exhibit that has just begun making its way around U.S. museums, and, hopefully, the world.

Engineers are masters of scale. They harness energy from the sun, wind, rivers, atoms, and ores. They manipulate electrons, photons, and crystals to compute and communicate. They devise instruments that detect perturbations in the fabric of space-time. And they grapple with challenges–anticipated or not–that are presented by the scale of the problem they are trying to solve.

The world's largest airplane, when it's built, will stretch more than a football field from tip to tail. Sixty percent longer than the biggest existing aircraft, with 12 times as much cargo space as a 747, the behemoth will look like an oil tanker that's sprouted wings–aeronautical engineering at a preposterous scale. ¶ Called WindRunner, and expected by 2030, it'll haul just one thing: massive wind-turbine blades. In most parts of the world, onshore wind-turbine blades can be built to a length of 70 meters, max. This size constraint comes not from the limits of blade engineering or physics; it's transportation. Any larger and the blades couldn't be moved over land, since they wouldn't fit through tunnels or overpasses, or be able to accommodate some of the sharper curves of roads and rails.
