Edinburgh-based aerospace startup Skyrora announced yesterday it had commenced a series of full-duration tests of its updated 3D-printed 70kN engine.  The new design features an improved engine cooling chamber and can be built approximately 66% faster at a 20% cost reduction. It is meant to take the company closer to commercial orbital launch later this year from the SaxaVord Spaceport that is being developed on Lamba Ness in Unst, Shetland.  Skyrora says the tests will evaluate various parameters, such as life cycle and full operational envelope testing, while the engine runs for 250 seconds — the same time it will…
