What happened

Engineers just designed a better 'shock absorber' for spacecraft Gaby Clark Scientific Editor Andrew Zinin Chief Editor Rocket launches are among the most violent ways humans have devised to travel.

Why it matters

They generate millions of pounds of thrust and subject passengers to intense g-forces.

Common ground

Humans must undergo serious training to withstand those forces, while machines must be designed to survive them.
