If they can do it, great, but the rocket equation really hates SSTO spaceplanes.
They’ve got 18 employees and $30M funding.
In the aerospace industry, that’s the equivalent of working out of your mom’s basement, with grand plans to someday move up to the garage.
File this one away under “check back in twenty years.”
We went down this road before with NASA and nothing ever came of it. If they can pull it off great but I don’t think that this is news until it’s built.
Rocket equation says ‘no’.
However, let’s take a step back and consider where else this tech might lead us. They will need to develop an air-breathing rocket engine, so a scramjet or similar, which is something that the military will definitely be interested in. Even longer term, a hypersonic scramjet plane would be the ultimate for long distance travel – the speed of a rocket combined with the glide capabilities of a plane would be superfast but also reasonably safe travel.
I really hope they make something that works, because of the cool factor of an SSTO spaceplane, but I’m just not seeing the mainstream application.
I’m skeptical in a world of reusable rockets, but we shall see.
