The final structure of the spacecraft would be finalized by 2006, based on the development in science and technology within that period.
However the technologies the spacecraft proposes to use are:
These technologies are termed as “ Mission architects'.
Coronagraphs operating at visible wavelengths- a coronagraph can be understood as an instrument that blocks the direct and diffracted light of a bright object, enabling vision of nearby objects and structures that are faint. This instrument has been used to study the corona of the sun.
Interferometers operating at mid-infrared wavelengths- in this technique mirrors separated wide apart work as a single telescope.
