This Science Daily version of a NASA release,
http://www.sciencedaily.com/releases/2012/11/121101164556.htm
describes an X-Ray telescopoe with an interesting mirror design, and an
interesting mission -- looking at the Sun for nano-flares.

This paragraph is especially interesting from a space policy viewpoint:

"By using such optics on the sounding rocket, Christe hopes they'll be
able to perfect their performance for use on a sun-observing satellite
some day. This is another benefit of sounding rockets: testing
innovative technology on a less expensive rocket sets the instruments
up for potential deployment on a permanent spacecraft. Instruments like
those on FOXSI will be important to nail down the mystery of what
causes these small flares and what they in turn effect."
