FISICA FP7 Project activities officially ended (31st December 2015) - but -
Far Infrared Space Interferometry studies continue !!

PROJECT MISSION:
- This programme seeks to design a spatial interferometer concept that
will be able to answer a variety of crucial astrophysical questions
such as how do planets and stars form, what is the energy engine of most
galaxies and how common are the molecule building blocks of life.
- This interferometer would operate at far-infared wavelengths and it
will be able to simultaneously determine both the spatial and spectral
nature of the target astronomical sources. At these extreme IR wavelengths
the Earth's atmosphere absorbs strongly which implies that it must operate
in space and adopt either a free flying a tether or a connecting boom
between satellites.
- A number of technologies will be studied to improve their readiness for
such a mission and a program simulating its performance will be compiled
to predict its performance.

PROJECT DESCRIPTION:
Impressive advances in our understanding of the environments in our own ( Milky Way) and other galaxies have been made by the Herschel space observatory with its unprecedented combination of spectral coverage and sensitivity, and its high angular resolution compared to previous facilities. But its angular resolution, which struggles to match the spatial detail which Newton had with his optical telescopes, is poor compared to that currently achieved in the optical and radio regions. This is problematic since the FIR is precisely the spectral region where most of the energy from star and exo-planetary systems and from galaxy clusters deep in space is radiated. To understand the nature of these objects it is thus crucial to get the clearest view by enhancing the spatial fidelity.
The FISICA team have proposed a novel instrument which is similar to the large ground based radio interferometers but which is designed to be placed outside the Earth's atmosphere to overcome absorption at these wavelengths. A key difference to the radio system is that the proposed interferometer will be able to provide both the spectral and spatial detail necessary to understand the physical nature of the astronomical sources.
Performing interferometry in space will be challenging as individual telescopes will be large (3m diameter) and we need several of them linked together. Options to consider for the interferometer telescope system include formation flying, large booms or tethered satellites. The FISICA team will study these and many other technical requirements to pave the way for such a pioneering mission.
