Scientists Discover Water On Surface of an Asteroid (space.com) 21

For the first time, scientists say they've detected water molecules on the surface of an asteroid. Space.com reports: Scientists studied four silicate-rich asteroids using data gathered by the now-retired Stratospheric Observatory for Infrared Astronomy (SOFIA), a telescope-outfitted plane operated by NASA and the German Aerospace Center. Observations by SOFIA's Faint Object InfraRed Camera (FORCAST) instrument showed that two of the asteroids -- named Iris and Massalia -- exhibit a specific wavelength of light that indicated the presence of water molecules at their surface, a new study reports.
While water molecules have previously been detected in asteroid samples returned to Earth, this is the first time that water molecules have been found on the surface of an asteroid in space. In a previous study, SOFIA found similar traces of water on the surface of the moon, in one of the largest craters in its southern hemisphere. [...]
Therefore, the findings at Iris and Massalia suggest that some silicate asteroids can conserve some of their water over the eons and may be more commonly found in the inner solar system than previously thought. In fact, asteroids are believed to be the primary source of Earth's water, providing the necessary elements for life as we know it. Understanding of the distribution of water through space will help researchers better assess where to search for other forms of potential life, both in our solar system and beyond. The findings have been published in The Planetary Science Journal.
