New Shepard as small sat launcher
« on: 06/30/2019 03:36 pm »
Would it be feasible for BO to put a second stage on New Shepard to use it as a small sat launcher with a reusable first stage?  I don't think they will do it as they are aiming to scale up, but it seems like it could be pretty competitive as a small launcher.

I don't think so. The New Shepard booster stage wouldn't have enough power to go straight towards space because of a low TWR. It's just too much weight.

It's theoretically possible. Jon Goff ran some numbers on Selenian Boondocks a while back: https://selenianboondocks.com/2016/01/random-thoughts-new-shepard-for-pop-up-tsto-nanosat-launch/
I tried it at home

It has around 3 times the thrust of Electron (490 kN vs. 162 kN)

Jeff Bezos has mention idea in passing. BE-7 would make an ideal US engine with bonus of using same fuel as booster. Could be they are waiting on BE-7 before proceeding.

A reuseable fairing which returns with booster would help lower costs. Fairing could encapsulate both US and its payload,  which should reduce mass of US.
