MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) is a Swedish research satellite designed for studying waves in Earth's atmosphere. Launch occurred on 4 November 2022 from the Rocket Lab Launch Complex 1 at the Mahia Peninsula in New Zealand.{{cite web |url=https://spacenews.com/rocket-lab-to-attempt-booster-recovery-on-upcoming-electron-launch/|title=Rocket Lab to attempt booster recovery on upcoming Electron launch|publisher=SpaceNews |date=3 November 2022 |access-date=4 November 2022}}{{cite news|url=https://www.svt.se/nyheter/vetenskap/svenska-satelliten-mats-ska-kartlagga-jordens-atmosfar|title=Svenska satelliten Mats ska kartlägga jordens atmosfär|publisher=SVT Vetenskap|author=Thomas von Heijne|language=Swedish|date=4 November 2022|accessdate=4 November 2022}}{{cite web|url=https://www.svtplay.se/video/37322609/nyheter-direkt/svensk-satellit-skjuts-upp-forsta-pa-over-20-ar-4-nov-18-15?info=visa|title=Svensk satellit skjuts upp|publisher=SVT Play|language=Swedish|date=4 November 2022|accessdate=4 November 2022}}

MATS is planned to study atmospheric waves, providing data for atmospheric models monitoring future changes in the mesosphere, the atmospheric layer 50-100 km above sea level. In particular, MATS is designed to measure noctilucent clouds and atmospheric airglow from oxygen molecules.{{cite web |url=https://www.su.se/english/research/research-projects/mats-the-next-swedish-research-satellite/mats-instrument-1.599544 |title=MATS instrument|publisher=Stockholm University |date=3 June 2022 |access-date=4 November 2022}}
