The payload is a science research satellite by space systems provider OHB Sweden for the Swedish National Space Agency (SNSA). The Mesospheric Airglow/Aerosol Tomography and Spectroscopy (MATS) satellite is the basis for the SNSA’s science mission to investigate atmospheric waves and better understand how the upper layer of Earth’s atmosphere interacts with wind and weather patterns closer to the ground. MATS was originally due to fly on a Russian launch service before the mission was manifested on Rocket Lab’s Electron.

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.
