Title: Detection of Water and/or Hydroxyl on Asteroid (16) Psyche
Author: Driss Takir, Vishnu Reddy, Juan Sanchez, Michael K. Shepard, Joshua Emery

In order to search for evidence of hydration on M-type asteroid (16) Psyche, we observed this object in the 3 micron spectral region using the long-wavelength cross-dispersed (LXD: 1.9-4.2 micron) mode of the SpeX spectrograph/imager at the NASA Infrared Telescope Facility (IRTF). Our observations show that Psyche exhibits a 3 micron absorption feature, attributed to water or hydroxyl. The 3 micron absorption feature is consistent with the hydration features found on the surfaces of water-rich asteroids, attributed to OH- and/or H2O-bearing phases (phyllosilicates). The detection of a 3 micron hydration absorption band on Psyche suggests that this asteroid may not be metallic core, or it could be a metallic core that has been impacted by carbonaceous material over the past 4.5 Gyr. Our results also indicate rotational spectral variations, which we suggest reflect heterogeneity in the metal/silicate ratio on the surface of Psyche.

Asteroid (16) Psyche is at Opposition on the 2nd March, 2012.

Spoiler

This chart shows the movement of Asteroid (16) Psyche from the 25th February to the 8th March, 2012  

Magnitude: 10.3
Distance to Earth: 2.239 AU
Distance to Sun:3.230 AU

The asteroid has an apparent magnitude of between 9.22 and 12.19

16 Psyche is one of the ten most massive main-belt asteroids.
It is over 200 kilometres in diameter and contains a little less than 1% of the mass of the entire asteroid belt.
It is the most massive of the metallic M-type asteroids.
Radar observations indicate a fairly pure iron-nickel composition.
Asteroid 16 Psyche might be the common parent for the enstatite chondrites.
Psyche was discovered by Annibale de Gasparis on March 17, 1852. In Greek mythology, Psyche was the deification of the human soul. She was portrayed in ancient mosaics as a goddess with butterfly wings (because psyche is also the Greek word for 'butterfly'). The Greek word psyche literally means "spirit, breath, life or animating force".
