AMA: We’re NASA experts studying comet 3I/ATLAS – the interstellar object passing through our solar system. Ask us anything!

nasa
replied to ntb899

It would be cool to scoop up the leftovers, but sadly not practical.

The dust and debris behind a comet gets very quickly dispersed through a couple of different mechanisms. But in some ways, we don’t have to leave home to study comet dust, because that’s exactly what meteor showers are! Earth passing through the debris trail of a comet, and the dust burning up in our atmosphere.

But keep in mind how (relatively) enormous the cross-section of Earth is in space, and even then there’s often only a few dozen shower trails per hour at peak. There’s no practical way a spacecraft could mop anything up without being very close to the source. -KB
