It still awes me that we can fire a probe at a moving object 180 million miles away with such accuracy and care that we not only reach it but have the probe gently touch down and then return to us.

- chronomex 8y agoYeah ... I can drive across the country and land in a particular parking spot with 100% repeatability.
- ur-whale 8y agoSure, but your motor-sensor feedback loop doesn't have a multi-minute delay built into it, so I'd say slightly less of a challenge.
- ceejayoz 8y agoAs a counter-point to the counter-point, if we could reliably predict the actions of other cars years into the future (as we can with solar system objects), multi-minute delays wouldn't matter much.
- AstralStorm 8y agoThe orbits perhaps but not the rotation (which can be improved in flight) nor surface conditions or surrounding "atmosphere", all being critical for landing. This is why chasing an asteroid or a comet is much easier than actually landing.
- laumars 8y ago...yet some people who live in the same village as me can never remember which village bus stop they need to get off (there isn't many - we only have a 300 houses) so spam the village Facebook group asking for help! I wish I was making this up!
