Congratulations to Rocket Lab and DARPA. I hope the experimental satellite works. It looks like an interesting mission. I can even envision that this antenna technology might be adapted for space telescopes.
I've noticed on this and previous launches that Electron seems to wobble a bit on its way up to orbit. Is that because it's so small and light?

DARPA has said little about R3D2 after its launch, but Warden’s comments suggested the mission was going well. “This successful demonstration will lend support to developing additional smaller, faster to launch and lower cost capabilities that can optimize the new commercial market for small, inexpensive launch vehicles by both the DOD and commercial users,” she said. “We’re extremely proud of this effort and I want to congratulate the entire team on its success.”
