Carrie Nugent er asteroidejeger - og del av en forskergruppe som jobber med å finne og studere våre eldste og mest tallrike kosmiske naboer. Hvorfor bry seg så mye om asteroider? Denne korte, faktafylte presentasjonen gir en oversikt over de mange fantastiske måtene asteroidene har vært med på å forme planeten vår på, og hvordan det å finne dem til riktig tidspunkt kan være med på å redde livet på jorda.

Petition your congressional representatives to support NASA. More than 95 percent of near-Earth asteroids have been discovered by NASA-funded surveys. If you feel strongly about this and are a US citizen, you can reach out to your representatives and express your support for NASA to continue the search.

NASA's Planetary Defense Coordination Office

The NASA office concerned with potentially hazardous objects (PHOs), which are defined as the asteroids or comets whose orbits get within 0.05 AU (an astronomical unit, the average distance between the Earth and the Sun) of Earth's orbit and are above a certain size. They are responsible for the early detection of PHOs, tracking and characterizing PHOs, providing timely and accurate communications about PHOs and coordinating the US government planning for a response in the case of an actual impact threat.
