Optical tweezers are powerful tools based on focused laser beams. They are
able to trap, manipulate and investigate a wide range of microscopic and
nanoscopic particles in different media, such as liquids, air, and vacuum. Key
applications of this contactless technique have been developed in many fields.
Despite this progress, optical trapping applications to planetary exploration
is still to be developed. Here we describe how optical tweezers can be used to
trap and characterize extraterrestrial particulate matter. In particular, we
exploit light scattering theory in the T-matrix formalism to calculate
radiation pressure and optical trapping properties of a variety of complex
particles of astrophysical interest. Our results open perspectives in the
investigation of extraterrestrial particles on our planet, in controlled
laboratory experiments, aiming for space tweezers applications: optical
tweezers used to trap and characterize dust particles in space or on planetary
bodies surface.
