SpaceX CRS-31, sometimes identified by NASA as CRS SpX-31, was an American cargo spacecraft flight to the International Space Station (ISS), which launched on 5 November 2024.

The instrument takes multiple daily measurements that determine the temperature and speed of electrons in the solar wind, along with the density information gathered by traditional coronagraphs.

A diverse international team has been designing, building, and testing the instrument since 2019 at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Their small size, low maintenance, ability to absorb water from the air, and tolerance of harsh conditions make them suitable for spaceflight.

Some micrometeoroids and space debris traveling at high velocities could perforate the outer surfaces of spacecraft, possibly jeopardizing mission success or crew safety.
