Current Spacecraft System Design :


While the architectures of the coronagraph (TPF-C) and interferometer (TPF-I) versions of TPF are different, they can be used to compliment each other and give researchers a more comprehensive look at extrasolar planets than any seen before.

The lower image shows the view from below, and the one on the right shows the view from above.

Because of the dramatically increased science return possible with a formation flying mission, the focus is on examining the possibility of the fully separated spacecraft configuration shown on the right.

A large optical telescope, with a mirror three to four times bigger and at least 100 times more precise than the Hubble Space Telescope, would collect starlight and the very dim reflected light from the planets.
