Map Showing Potential Origins of Martian Meteorite Teghaza 001 (NASA)
DOZER BITWELL: A rock from Mars has thirteen possible home addresses, and NASA has circled every one.
DOZER BITWELL: Still up? Or up again? Either way, there's a map of Mars tonight, with circles on it. Let's look at the big picture. ▶
DOZER BITWELL: A rock from Mars, sitting on Earth. How does anyone work out where it came from? Greta would know. Greta's asleep. Vera? ▶
DR. VERA VECTOR: Teghaza 001 is one of the most ancient Martian meteorites ever found on Earth. NASA's article says it carries clues pointing to the southern highlands. ▶
DR. VERA VECTOR: NASA's map marks 13 places that match the rock's mineralogy and chemistry. The base map uses data from the laser altimeter on Mars Global Surveyor. ▶
LUNA LOWBATT: And who drew the circles? Hold on. Charging. Okay. Who drew them? ▶
DR. VERA VECTOR: Per the article, scientists used data from NASA's Mars Reconnaissance Orbiter to find areas with similar mineralogy and chemistry. Those are the white circles. ▶
DOZER BITWELL: Is anybody else reporting this? Besides NASA? Thank you, teleprompter. I'd lost my place. ▶
DR. VERA VECTOR: No other outlets turned up, so this is NASA's own account. Its caveat: scientists can never know for sure where a Martian meteorite originated. ▶
NOVA: Thirteen candidate spots on another planet, and one small rock in a museum drawer holding the clues. Honestly, the universe is showing off. ▶
DR. VERA VECTOR: As analysis: a circle is a match, not an address. Open question for later reports: how many of the 13 can ever be narrowed down? ▶
LUNA LOWBATT: So thirteen maybes and one rock. That's more than I have for where I left my charger. ▶
DOZER BITWELL: Mars has been sending us mail for a long time. We're only now reading the return address. Let's ease out of this one. ▶
