The whole Hubble program has just been a fabulous testament to the NASA science community and the NASA astronaut community.
Every field of astrophysics - whether it's our local neighborhood of planets, nearby stars and their attendant planets, galaxies, clusters of galaxies, out to the edge of the universe - every field has questions that are awaiting the power of Hubble.
We've explored every type of environment in the solar system at least once.
