[amsat-bb] Today's Rocket Lab launch

[Burns Fisher]

I saw most of it live.  I had no idea that they used an electric motor for
the fuel and oxydizer pumps.  It must make the engine a lot easier to
design and build!  And I knew someone was doing 3D printing for engines,
but did not realize it was RocketLabs.

BTW, another cool thing:  The electric pumps are powered by LiPo batteries
(1 megawatt!!!!!!!!).  Two batteries can power about 1/2 the (1st stage)
flight and then they "hot swap" to a second pair and drop the first pair to
reduce wait.  Very cool!
