New Zealand's Rocket Lab has won a contract that may send two of its Photon spacecraft on a mission to Mars in 2024.
The firm is to design the craft for NASA's Escape and Plasma Acceleration and Dynamic Explorers mission - known as ESCAPADE.
It'll put craft into orbit around Mars to study its magnetosphere, to better understand how solar wind removes atmosphere over time.
Rocket Lab CEO Peter Beck spoke to Corin Dann.
