Marine turtles spend almost their entire lives at sea – but little is known about the paths they take. Now, satellites are helping scientists map their movements during the "lost years".
Air pollution from satellites burning up in Earth's atmosphere could become the world's next big environmental problem — but the tricky form of contamination seems to evade the reach of both international space treaties and Earth-focused environmental laws. So, some researchers are suggesting a solution: Maybe chemicals produced during satellite reentries should be incorporated in the 1987 Montreal Protocol which bans certain substances that can harm our planet's protective ozone layer.
