More specifically, go about 200 kilometres west of Crete, then straight down to the bottom of the Mediterranean Sea 3.5 kilometres below. Swarming spacecraft to self-destruct for greater good - space - 06 September 2010. Future space probes that operate in cooperative swarms must commit hara-kiri if they begin to fail and risk damaging their comrades, says a recent patent application by NASA.
The agency foresees a day when space missions are undertaken not by one large spacecraft but by swarming formations of much smaller, cheaper ones. Such craft could collectively provide a "floating optics" system for a space telescope comprising separate craft flying in formation, for instance. However, should one spacecraft in such a swarm begin to fail and risk a calamitous collision with another, it must sense its end is nigh and put itself on a course that takes it forever away from the swarm – for the greater good of the collective. Failing that – perhaps because it has too little fuel to move – it must "passivate" itself by deactivating all its systems. This would mean discharging its batteries so as to pose no risk of shock in a collision, and venting any last vestiges of fuel that could explode in a crash.
Courgettes, judo throws and bear attacks on humans. "Put the courgette down, lady" (Image: Mike Tan.C .T/Shutterstock) Rowan Hooper, news editor I'm glad it's not just me who loves stories about encounters between bears and humans.
As I write, at least 541 news sources around the world including The Guardian and the BBC have picked up the story of a Montana woman throwing a courgette (aka a zucchini) at a bear she encountered in her house. It reminded me of a story of a man gathering mushrooms in Kanagawa Prefecture, Japan, who was attacked and bitten by a bear.
What the bear wasn't expecting was that the mushroom picker was a judo expert, who simply threw the bear on its back.
