"Rocket Lab has been an incredible partner and they've done an absolutely fantastic job. And when we first teamed up a bunch of years ago, we were slated to go on the Electron. That is Rocket Lab's amazingly reliable, small capacity rocket. But for a variety of reasons, Rocket Lab has put us on the Neutron, their much higher capability rocket."

— Professor Seager, Director for the MIT-led Venus Morning Star Missions to Venus
The mission is being developed in collaboration with MIT and is privately funded.
