I can certainly understand the upgrade based on the performance advantages
What would NASA use for its mapping GIS/Mapping software?
Postgres has PostGIS
Oracle has OracleSpatial
MySQL has ?
Many Thanks for the link

I think you missed something in your formula,
You just have a 1 dimension dealt with here.
That would be every grain in that line.
But when i first read the statement before i had the same conclusion that
10^30 would normally be enough for anyone, I noticed years ago Nasa used

NASA switches from Oracle to MySQL
In November a team at NASA's Marshall Space Flight Center finished the
transition of the NASA Acquisition Internet Service (NAIS) from Oracle to
MySQL. NAIS sends e-mail notifications to users based on specified interests
and enables users to query the Web site (nais.nasa.gov) for updated
Dwight Clark, project leader of NAIS, claims to have noticed an increase in
speed of performance without experiencing any problems.
The switch to Open Source software was primarily driven by costs, and MySQL
was found to be the most robust product available. The President's
Information Technology Advisory Committee recommended in September that the
federal government encourage open-source software as an alternative for
software development for high-end computing and allow open-source
efforts to compete on a "level playing field" with proprietary solutions in
