SUMMARY: NASA is considering a new space-based telescope that would be the equivalent of a 40-metre (120 ft) observatory. The proposed Space Infrared Interferometric Telescope (SPIRIT) mission would consist of two infrared telescopes at opposite sides of a rail that could be positioned perfectly to combine their images into a single, giant telescope. SPIRIT is being considered as part of NASA's Origins program, which is looking to answer fundamental questions about the beginning of the universe. If selected, it would launch in 2014.

The article didn't say anything about how large the individual primary mirrors for this device are. The image associated with this story makes it look like the dishes are going to be about ten meters each, but that seems like an unbelievable size to get launched to an L2 orbit.
