It's about garbage collection. You seem to be keen to deorbit what they collect. Okay. How many metric tonnes of garbage are we collecting? Is there an estimate?

That's one answer, especially if the final usage is downwell. If it's for orbital or luna construction, you never deorbit to Terra. You thinking parachute/water? I'd rather keep in orbit and start building a space elevator. :-) or a polar shield/mirror :-)

We had plans to do this in the 80s. This is ....hmm. how did you think we are going to mine the asteroid belt? You catch a rock, put it in an Earth crossing orbit, and refine it on the trip home. The energy is free, just lots of focused light. You set the asteroid in a slow tumble so it heats evenly. Return to Earth orbit with a few tons of refined metals and other goodies, probably already presold.

You don't. You catch it, heat it with mirrors and lenses. Smelt out the metals. Radio tag for recovery, leave iit at L4.

When you look at the night sky, you see a spacetime mosaic. All of the photons (light) reaching your eye come from different time periods. If that star is 40ly away then the light you see took 40 years to arrive st your eye. The star right next to it is 400ly distant and those photons have been traveling 400 years. A representation of spacetime.

And here I thought the earth was flat! :-) I really loved that dodge about talking about mass. 9.7 from the judge in NYC lol:-)

I think I'd lose consciousness right around 5G of acceleration. If I wake up, I'll send email. :-)

Laughs. I can only imagine it's worse if iit happens on a P.A.T.H. platform.

Grinz, nod, yup. Wake me up when we have an O'Neill colony at L4. Or when we can explain the math of null gravity versus microgravity :-)

Depends on relative masses. Terra and Luna are following a barycentric orbit of Sol :-)

Hmm. No circadian rhythm, but something more complex. Tides very high when both moons in conjunction. Increased vulcanism in tectonics from gravitic stresses. Lots of effects on biology.

Better hope that parachute works. Might make a good splash at terminal velocity. Keep it in orbit. Smelt when we build the infrastructure.
