Rapid Response Foreign Objects in Space Plan
Of all the times to want to land a probe on an object in our solar system, Oumuamua might have been the first which would require a rapid response. Imagine if we landed probes on Oumuamua and could get samples and images sent back to earth, or a remote lab on the ISS. A still say it's an alien probe, we're just not sophisticated enough to understand it.
A year later, we still don't know what it is, https://www.quantamagazine.org/interstellar-comet-oumuamua-might-not-actually-be-a-comet-20181010/.
