Top post: @ashleevance “On this Iridium deal and RKLB's next launch The distance that SpaceX and Rocket Lab are putting between themselves and rivals is starting to look insurmountable. Rocket Lab still needs Neutron to fly and fly often and this is no small feat. But these two companies have put together so many pieces and remain the only ones that can launch faster than everyone else after ALL these years. They have just figured things out that others can't. Rocket Lab is so valuable now that the math gets hard. But it just feels more and more like we head toward some world where it's merged with Blue Origin”
