NASA held a briefing to disclose the rocks returned by the OSIRIS-REx asteroid mission. The asteroid materials was delivered to Earth in late September in an area capsule that landed in Utah.
MARY LOUISE KELLY, HOST:
Rocks which might be older than the Earth. Pictures of them had been unveiled right now by NASA because the area company confirmed off pebbles and mud that it collected from an asteroid greater than 200 million miles away. The asteroid materials was transported to Earth by an area capsule that landed in Utah late final month. NPR’s Nell Greenfieldboyce studies that thrilled scientists are slowly sorting via what was inside.
NELL GREENFIELDBOYCE, BYLINE: An enormous crowd gathered at NASA’s Johnson House Middle in Houston to lastly see the rocks introduced residence from an asteroid named Bennu by the seven-year-long OSIRIS-REx mission. There have been college youngsters, reporters, representatives of elected officers, greater than 20 minutes of speeches. Then NASA Administrator Invoice Nelson requested…

BILL NELSON: You able to see the outcomes of the mission?
(APPLAUSE)
NELSON: Take a peek.
GREENFIELDBOYCE: A display confirmed a picture of the a part of the spacecraft that truly touched Bennu, a pattern assortment machine that appears like a spherical steel air filter. Sitting on high was a small pile of black mud and tiny rocks. They regarded shiny, kind of like bits of contemporary asphalt.

DANTE LAURETTA: Belief me, I spent the weekend looking at this picture for hours and hours and getting extra excited by the day.
GREENFIELDBOYCE: Dante Lauretta is the lead scientist for this mission. He is with the College of Arizona. He excitedly pointed to variations between the little rocks.
(SOUNDBITE OF ARCHIVED RECORDING)
LAURETTA: Bennu has a salt and pepper form of texture, brilliant grains and darkish grains. And we’re seeing that. In truth, as I used to be zooming round these photos, I felt like I used to be miniaturized and operating round on a tiny, little Bennu.
GREENFIELDBOYCE: Early exams within the lab present that the asteroid materials accommodates water bearing clay minerals. And Lauretta says asteroids could have delivered water to the early Earth, creating our oceans and making it liveable. The rocks additionally include one other key ingredient for all times, carbon, and there is quite a lot of it. Daniel Glavin is a pattern analyst with NASA’s Goddard House Flight Middle.

DANIEL GLAVIN: On the time this information got here again, I imply, there have been scientists on the staff going, wow, oh, my God.
GREENFIELDBOYCE: The rock appears to be loaded with natural materials. Asteroids may need seeded Earth with it.
(SOUNDBITE OF ARCHIVED RECORDING)
GLAVIN: OSIRIS-REx, the staff, we picked the proper asteroid. And never solely that, we introduced again the proper pattern, proper? These items is an astrobiologist’s dream.
GREENFIELDBOYCE: And to this point, researchers have solely been wanting on the filth and grains of rock caught to the skin of the pattern assortment machine. Scientists nonetheless have not opened that machine up. It is a painstaking course of. And the majority of the rocks nabbed from Bennu are nonetheless locked inside.
