The Columbia STS-107 mission lifted off on January 16,
2003, for a 17-day science mission featuring numerous
microgravity experiments. Upon reentering the atmosphere
on February 1, 2003, the Columbia orbiter suffered a
catastrophic failure due to a breach that occurred during
launch when falling foam from the External Tank struck
the Reinforced Carbon Carbon panels on the underside of
the left wing. The orbiter and its seven crewmembers (Rick
D. Husband, William C. McCool, David Brown, Laurel
Blair, Salton Clark, Michael P. Anderson, Ilan Ramon, and
Kalpana Chawla) were lost approximately 15 minutes
before Columbia was scheduled to touch down at Kennedy
Space Center. This site presents information about the STS-
107 flight, as well as information related to the accident and
subsequent investigation by the formal Columbia Accident
Investigation Board.

Every solver object contains the data of and the numerics for one
block.The solver class is sent from the client to the server that is,
different users may use different solvers.
