Media Advisory – Webb’s Fine Guide Sensor Provides Insight

LONGUEUIL, QC, July 6, 2022 /CNW Telbec/ – Webb’s The Fine Guidance Sensor (FGS) – developed by the Canadian Space Agency (CSA) and designed to find and lock onto cosmic targets – recently captured a view of stars and galaxies that offers tantalizing insight into what The telescope’s scientific instruments will reveal in years to come. weeks, months and years.

This technical test image captured by Canada’s Fine Guidance Sensor (FGS) on Webb, in 72 exposures over 32 hours in May 2022, offers a unique insight into the power of the space observatory. While Webb’s four science instruments will ultimately reveal the telescope’s new view of the universe, the FGS is the only element that will be used in every Webb observation during the life of the mission.

FGS has always been able to capture images, but its main purpose is to enable precise scientific measurements and imaging with precise pointing. When it captures images, these are generally not retained: given the limited communication bandwidth between L2 and Earth, Webb only sends data from two scientific instruments at a time. But during a week-long stability test in May, the team found they could retain captured footage because there was data transfer bandwidth available.
