Looks like another team (company) going for low cost access to space.
As a plus, they are bringing with them a lot of experience with rockets.

Interesting concept with the aerospike, a bit more complex than the one we are working on for a solid sugar motor (to cut down on the weight of our current stainless steel nozzles). Using composites should also cut down their weight.

We had success in using composite cases for our solid propellant MiniSShot motor aft burn but trouble with heat soak for the second burn leading to CATOs of several motors. They shouldn't have that problem since they are using methane/LOX as their propellant. I wish them success.

10 independent thrust chambers on the first stage? Not entirely sure how that ends up as simple and safe, but I guess we will see.

Apparently they now have a SAA agreement with NASA for technical development help.

Quote:
The agreement’s intended purpose is for Firefly and NASA to collaborate as related to the design and commercial development of Firefly’s Alpha launch vehicle, specifically in the areas of technical consultation, engineering services, and concept/design reviews.

Well, the SpaceX Falcon 9 has 9 Merlin engines and they claim safe/lower cost.

We shall see how the Falcon Heavy does with 27 engines if it ever launches.

The Falcon 9 is a much larger rocket.

Space X is also claiming that most of its lowered costs are still not directly related to hardware. If the Merlins cost twice as much, it might not even show up in the bottom line.

But with these miniature launchers, you have to start seeing real weight and performance issues.
