Small spacecraft, shaped by the forces that shrunk your cellphone, are changing the way we observe space and understand our home.
AFTER A PERIOD of wildfires, hurricanes and nuclear threats, it isn’t hard to see the value in being able to surveil the Earth with daily – or even more frequent – updates. But traditional satellites, which cost trillions of rand, have orbits that mean they may not see the same target for a week or more. So an Earth-imaging company called Planet, in San Francisco, is doing something different. In the past year, it has sent nearly 150 satellites into space, including a record 88 at once from India on Valentine’s Day. That should be unthinkable, but Planet is using CubeSats, an emerging type of small satellite made possible by the miniaturisation of electronics and sensors, like those in smartphones, that are creating new possibilities to use space technology for social and economic purposes.

Making the most out of your grinder
THE HUMBLE BENCH GRINDER IS A STAPLE of the handyworker's home shop, largely due to its versatility.

F1 taught me that speed starts with comfort
AS A FAN OF MOTORSPORT, I'M ALWAYS fascinated with the finer details that go into Formula One racing. Piloting the fastest racing cars on the planet subjects drivers to savage forces - up to 6 G's under braking which has led to an almost endless pursuit of comfort.
