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,

    d(Ma)/dt

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....
