John Scovill No. I really hate that Blue origin is considered number 2 in new space. It ignores Rocketlabs which has already delivered several commercial satellites in orbit. Rocketlabs is number 2 and Jeff Bezo's company is not even a contender.

Rn1024 No Blue origin has no experience on heavy lifting they did not even reach orbit. Heavy lifting is all about delta V and orbital rockets has higher delta V than suborbital rockets. If you do not reach orbit then your rocket is puny.

@nagaea7409 Blue Origin is a suborbital launch project and there is no evidence that this will change in the next few years. Meanwhile Rocketlabs is putting commercial satellite in orbit yet everyone dismiss them. Rocketlabs is a more capable launch company with healthy revenue stream. Blue Origin is simply Jeff Bezos vanity project and will be dissolve once he is bored with it.

@nagaea7409 I could not find the mass and specific impulse of BE-7 so there is no reasonable way for us to judge how it compares to Rocketlab"s Rutherford engine. I also could not find the mass and specific impulse of BE-3. Blue Origin is all smoke and mirror design to fool people who could not input numbers into the rocket equation. In order to claim BE-7's superiority we need 3 numbers the specific impulse, the mass, and the thrust output. Having the thrust output alone is useless in measuring an engines performance. Also in terms of throttle ability Rutherford engine can go from 0 to 100% thrust. BE-7 has double the thrust of Rutherford but without engine mass we do not know if Rutherford can beat BE-7 by simply doubling the number of engine.

@nagaea7409 Nasa did a complete review of the National teams proposal so I defer to them in terms of the merits of the propose architecture. What I have problems is the constant over estimation of Blue Origin's capability.

Rn1024 No it cannot do that because it is a paper rocket. And they will not test a real hardware doing unmanned flight to do land, launch and moon insertion operation. Which makes their system dangerous. This overestimation of Blue Origins capability that whatever they do will work the first time even if they have zero experience in actual orbital operation. And they are so arrogant that their proposal omits unmanned testing of actual moon landing.

@nagaea7409 Blue Origin is all smoke and mirrors but no show. Rocketlabs should have more attention than them because they have an orbital class rocket not the puny suborbital rockets Blue Origin use to fool people into thinking that they are relevant. Blue Origin should be rank with amateur rocketeers that can only deal with suborbital rockets. That is the limit of their capability and they have not shown the ability of growing out of that limit.
