New data collected from the Cassini spacecraft have revealed complex organic molecules originating from Saturn’s icy moon Enceladus, strengthening the idea that this ocean world hosts conditions suitable for life.
LASP research scientists Sascha Kempf and Sean Hsu co-authored a new study, published in Nature, based on the data.
Very little was known about Enceladus prior to 2005—the year when Cassini first flew by. Since then, it has become a continuous source of surprises, with secrets still being revealed even now, after the end of the mission.
LASP Associate Director Tom Woods knows about space gunk.
As the principal investigator for the Extreme Ultraviolet Variability Experiment (EVE) aboard NASA’s Solar Dynamics Observatory, he’s all too familiar with the ways that exposure to the harsh space environment can lead to a spacecraft instrument’s degradation.
NOAA’s GOES-17 satellite has transmitted its first data from the LASP-built Extreme ultraviolet and X-ray Irradiance Sensors (EXIS) space weather monitoring instrument.
EXIS continually monitors the brightness of the Sun. Every 30 seconds, EXIS will create a picture of the Sun’s output in the part of the spectrum which includes X-ray and ultraviolet light—wavelengths that are absorbed by the outermost layers of our Earth’s atmosphere and ionosphere.
