That means the mission has way exceeded its goal of bringing 60 grams of asteroid samples back to Earth — especially since NASA scientists have yet to open the primary sample container that <a data-i13n="cpos:2;pos:1" href="

<p>The scientists are processing the samples inside a specialized glovebox (pictured above) with a flow of nitrogen in order to keep them from being exposed to our atmosphere and any contaminants. They can't just use any implement to break the container's fasteners open either: The tool must fit inside the glovebox, and it also must not compromise the samples' integrity. NASA has sealed the primary container sample for now, while it's developing the procedure to be able to open it over the next few weeks. </p>

inside TAGSAM, taken by holding down its mylar flap and reaching inside with tweezers or a scoop. NASA's initial analysis of the material <a data-i13n="cpos:4;pos:1" href="
https://www.nasa.gov/news-release/nasas-bennu-asteroid-sample-contains-carbon-water/">published[/url] earlier this month said it showed evidence of high carbon content and water, and further studies could help us understand how life on Earth began. The agency plans to continue analyzing and "characterizing" the rocks and dust it has already taken from the sample container, so we may hear more details about the samples even while TAGSAM remains sealed.</p>This article originally appeared on Engadget at
