OK, here's a proposed definition:

Define Ma, the mass raised above the atmosphere by human activity. (shuttles,
satellites, probes, etc). The tendency to do so is the derivative, ie,


I invite anyone with the required data and a strong interest in space to
look up the numbers and provide a yearly table, starting with Sputnik.

There are actually a series of derivatives here:

d(Ma)/dt - Mass into LEO and beyond
d(Mtev)/dt - Mass beyond Terran Escape Velocity (tev)
d(Msev)/dt - Ditto, Solar Escape Velocity
d(Mgev)/dt - Ditto, Galactic Escape Velocity
d(Mlgev)/dt -
d(Mu)/dt -

The last two are left as exercises for the reader....

For SETI enthusiasts, there is d(b)/dt, where b is bits....
