SART crashes into an asteroid... for Science!

Year 25, Day 355

The SART probe (Single Asteroid Redirection Test) has crashed into asteroid Kimorphos and the results are stunning.

SART was a test; a test to see if we could nudge an asteroid out of the way (potentially if one was coming towards Kerbin) by ramming a spacecraft into it. The SART probe was roughly the size of a large vending machine; it weighed about 2 tons. The smartest Kerbals alive calculated that this would be enough to nudge the targeted asteroid, named Kimorphos, by a considerable amount.

When the test was conducted, it was quite spectacular. But the question remained: did the test actually nudge the asteroid at all?

It turns out, yes, it did! It enlarged the asteroid's orbital semimajor axis around Kerbol by thousands of kilometers; exactly what they had predicted would likely happen.

This test was a weird one, sure, but one that just had to be done; after all, what else would Kerbals do if a huge deadly asteroid was coming towards Kerbin? Last-minute fixes would be unreliable; something planned for that day from the past is a much better case.
