Since I'm also invested in RKLB
$Rocket Lab (RKLB.US)$ and also don't know anything about ASTR, Rocketlab has a lot going for it.
They own and operate their own launch space and have been acquiring great companies. They are becoming a one stop shop for low orbit satellites. They can work with a company to custom tailor the whole process. They have succesfully launch over 100 satellites as well.
They have a new rocket on the way, Neutron, that will allow for large pay loads and possibly human travel.
They are winning government and commercial contracts with a large growing backlog.
As other point out, this is probably an investment that will take a few years to really start to pay off, but overall they have a lot of great things going for them.
I think the satellite industry is really where the money is going to be.
