The "Baby Come Back" mission includes NASA's Starling project, which consists of four CubeSats designed to test technologies for future swarm missions. Telesat contributes the LEO 3 demonstration satellite, ensuring continuity for customers and ecosystem vendor testing. Additionally, two 3U satellites carrying GNSS-RO payloads from SpinGlobal will replenish their constellation of over 100 multipurpose satellites.

Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage. It is also used as a suborbital testbed (called HASTE) for hypersonics research.

Rocket Lab is an American aerospace manufacturer with a wholly owned New Zealand subsidiary. The company develops lightweight, cost-effective commercial rocket launch services. The Electron Program was founded on the premise that small payloads such as CubeSats require dedicated small launch vehicles and flexibility not currently offered by traditional rocket systems. Its rocket, the Electron, is a light-weight rocket and is now operating commercially. The company is also producing a variety of spacecrafts and spacecrafts components.
