Watch as rocket engines test-fired at Shetland space port

A rocket manufacturer has successfully tested rocket engines at a space port on Shetland.German-based Rocket Factory Augsburg said the start of its "hot-fire test campaign" at SaxaVord Spaceport had run "flawlessly".To successfully launch into orbit, powerful engines are required that can break free from earth's gravity, and these engines are tested in advance. A total of four Helix engines were hot-fired, with them being ignited one by one at four second intervals.

All engines ran simultaneously for eight seconds.
