Due to its location and climate, Antarctica offers unique conditions
for long-period observations across a broad wavelength regime,
where important diagnostic lines for molecules and ions can be found,
that are essential to understand the chemical properties of the interstellar
medium. In addition to the natural benefits of the site, new
technologies, resulting from astrophotonics, may allow miniaturised instruments,
that are easier to winterise and advanced filters to further
reduce the background in the infrared.
