OH SHIT: Nasa Can Make Fake Clouds?

Saturday night, on the East Coast, if you saw some strange looking clouds, it wasn't the shrooms you ate... it was NASA.
By using the exhaust particles from the fourth stage of a NASA Black Brant XII suborbital sounding rocking, NASA briefly created noctilucent clouds which are also known as night-shining clouds. These are the highest clouds naturally found on Earth and are normally found around 50 miles above Earth at high latitudes. NASA conducted this test not only to spark a bit of hysteria, but also to study the effect of rocket exhaust in the upper atmosphere.
