FURST

Mission Overview

FURST (Full-sun Ultraviolet Rocket SpecTrometer) is an experimental sounding rocket instrument that will provide a solar-stellar "missing link", to enable unique insights into the heating of the Sun's chromosphere and corona, with more general implications for understanding signatures of magnetic reconnection and other magnetic processes in the Universe.

We will deliver a fully calibrated UV spectrum to the community at the earliest opportunity, to enable collaborations across heliophysics, astrophysics and aeronomy of planetary and exoplanetary atmospheres. Our initial science interest is to understand better the processes of chromospheric and coronal heating, by focusing upon sometimes subtle, yet significant differences in high quality ultraviolet spectra of the Sun and the stars.

Status

FURST was launched from White Sands Missile Range in New Mexico on September 3, 2024. The flight was successful and nearly everything operated as expected. Alas, a stray light leak in the instrument caused the detector to be saturated for almost the enitre data collection portion of the flight. SSEL and the science team are hard at work diagnosing the cause of the light leak. If the problem can be addressed, then FURST will be slated for a re-flight in the next year.

A news release has been published by MSU that goes into detail on the FURST mission.
