Mission Statement
STEAM will advance understanding of solar flares and help identify why the
solar corona is far hotter than the solar surface by measuring enhancement of key elements and temperature
in solar flares and solar active regions. It will do this by measuring the Sun’s X-ray spectrum in quiet
conditions, with visible active regions, and during solar flares. STEAM is a subsidiary to the PUNCH NFI
Observatory and will meet all thermal, structural, and electronic requirements imposed by the PUNCH project
proposal.
