In a rare "time-critical" decision, the James Webb Space Telescope will study the true size of the "potentially hazardous" asteroid 2024 YR4 twice over the next few months. The asteroid has a roughly 2.3% chance of impacting Earth in 2032.
Yeah, I misspoke. I meant “will miss”, we’ve got enough observations that we know the “keyhole event” that was a possibility is no longer a possibility.
I think it’s hard to justify since we’ve already done a successful asteroid rendezvous (a few, IIRC) and it’s unclear (to me) what we could learn from studying the surface of this particular one or even studying from the surface of this one.
If we knew how to move it from solar orbit to terrestrial or lunar orbit and then use it as raw materials, that might be profitable. Or at least a nice engineering challenge on the way to profitable asteroid mining. But, I think the delta-V we’d have to achieve for that might me more than we are capable of right now.
I do wonder if we could put something on it and use it as part of a measurement tool, like how they can stitch together multiple 'scope sensors? I forget what the name of that is. Differential capture? Diffusion imaging?
It is an interesting opportunity, we rarely get such close flybys well predicted, but someone closer to the science / smarter than me would have to put together a mission plan.

Fair. All jokes and nihilism aside. Someone should take advantage of the flyby to send something up to study it.

Hence my wanting it done. ‘We don’t get close flybies all that often. Make the most of it.’
