Most Efficient Rocket Engine Ever Flown Will Enable Affordable Mach 9 Hypersonic Speed

We are trying to get there and this is about half way.  It is obviously a missle component.  Certainly no raptor.  We so want to fly straight into space with a hundred tons of payload, then return with a serious payload.

our jet engines take us half around the globe.  That took several decades.  Maybe I need to be patient.  Our rocket can jump one hundred tons half way around the globe today in less than an hour.  understand that is what will pay for thousands of launches tomorrow everywhere.

Those same rockets can haul a hundred tons to a bicycle wheel space station producing one g on the rim factory and living space.  We can now do this.

Flying directly into space still beckons.

Venus Aerospace has made the most efficient rocket engines ever flown. They will go from runway to mach 9 hypersonic speed. The Venus Aerospace Stargazer M4 is designed to reach a top speed of Mach 9, which is approximately 6,900 mph. While its cruise speed is planned to be around Mach 4-5, the engine combination for the Stargazer M4 is capable of reaching Mach 9 at its maximum velocity.

Combining a ramjet with the Venus RDRE–the most efficient rocket engine ever flown, the VDR is the most viable solution to take you from take-off to Mach 5.

Due to its simple design, standard materials, engine efficiency, and reusability, the VDR is affordable to produce, operate, and maintain, delivering revolutionary capabilities at lower cost.
