The first flight of Blue Origin’s New Glenn rocket seems to have a payload. Instead of launching a sports car, as SpaceX did with its first Falcon Heavy rocket, Jeff Bezos’s space company will likely launch a pair of Mars probes for NASA.

NASA is aware of the risk of launching a real science mission on the first flight of a new rocket. But this mission, known by the acronym ESCAPADE, is relatively low cost. The Escape and Plasma Acceleration and Dynamics Explorers mission has a budget of approximately $79 million, significantly less than any mission NASA has sent to Mars in recent history.

This mission will use two spacecraft to measure plasma and magnetic fields around the red planet. With simultaneous observations from two locations around Mars, scientists hope to learn more about the processes that strip away atoms from the magnetosphere and upper atmosphere, which drive Martian climate change.
