Our planet has been rocked by many-a-meteorite, and they鈥檝e left not just themselves as space debris but also craters and even molecules needed for life. Now we鈥檝e started to travel to them, and they might be a key part of our forays into deep space. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we鈥檙e talking about #meteors and asteroids, and why they should matter to those of us living down here on earth.
