Former Missions

Cassini VIMS

With this view, Cassini captured one of its last looks at Saturn and its main rings from a distance.
The VIMS instrument on the Cassini spacecraft has several unique capabilities. It is able to identify the chemical composition of a surface, atmosphere, or Saturn’s rings by measuring the visible and infrared energy.

GRAIL

The Gravity Recovery And Interior Laboratory (GRAIL) will unlock the mysteries of the Moon. By mapping the lunar gravitational field globally —not just on the nearside —to unprecedented accuracy and resolution, GRAIL will, in essence, peer deep inside the Moon to reveal its internal structure and thermal history.

MESSENGER

The pioneering MErcury Surface, Space Environment, GEochemistry, and Ranging (MESSENGER) mission will orbit the mysterious terrestrial planet, looking closely at its surface, its crust, its atmosphere—even its magnetic field.

Rosetta's VIRTIS

VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) is an imaging spectrometer onboard the Rosetta spacecraft. It will map and study the nature of the solids and the temperature on the surface of the nucleus.
