The radio sky at frequencies below ~30 MHz (wavelengths longer than ~10 m) is virtually unobservable from Earth due to the opaqueness of the ionosphere. Deploying an Ultra-Long-Wavelength (ULW) radio telescope in space would open this frequency band for science in astronomy, cosmology and space science.
In the context of the joint ESA-CAS mission opportunity (1) , a Chinese-European team is preparing an ULW radio interferometer mission proposal “DSL”. This concept was presented at the 2nd ESA-CAS joint mission workshop in Copenhagen in September 2014 (2).
A one-page summary discription of the proposed mission and its science can be found here.
The aim of this workshop is to discuss science themes which can be addressed with a long-wavelength interferometer in space, such as DSL. The science themes considered for the DSL mission includes:
The science workshop starts off with a session describing the DSL system concept and related technologies with the aim to clarify the system parameters which define the scientific capabilities.
The workshop will also include a discussion concerning parties’ interest in participating in the DSL endeavour.
