A Falcon 9 rocket will hit the Moon this summer at 7x the speed of sound (arstechnica.com) 1 points by staplung 2mo ago ↗ HN
[–] bell-cot 2mo ago ↗ Eric knows there's no sound on the Moon. At least his(?) subtitle -> The object will be traveling at 2.43 km a second, or 5,400 mph, upon impact.- is not a science education fail. [–] gus_massa 2mo ago ↗ Most of the times the title is written by someone else. My guess is that they go to something like https://www.wolframalpha.com/input?i=2.43+km+a+second [1] and copy the most clickbaity version.[1] I didn't get 7x speed of sound, but you may be more lucky.

[–] dlcarrier 2mo ago ↗ Space isn't a perfect vacuum, especially so near the moon, so there is theoretically a speed of sound, it's just really slow.

Come on Berger, you're better than that.
