It was set to be the world's first flight test for an aerospike rocket engine, but the MIRA I prototype crashed on takeoff before the most innovative part of its propulsion system could fire. Undeterred, Polaris is building two bigger prototypes.

How very inconvenient for them.

I wish them every success on their new build and look forward to seeing their linear aerospike nozzle engine flying soon.

To clarify this post/article has nothing to do with Dawn. Polaris is another startup also developing a spaceplane.
