elements and compounds - 7.6a, 7.6b
based on images, scientists believe osiris-rex grabbed 4 1/2 pounds (2 kilograms) of rubble, a full load. the minimum requirement had been 2 ounces (60 grams) — a handful or two.
\just imagine a sack of flour at the grocery store,\ lauretta said of the initial haul.
but tens of grams of material were lost following the successful touch-and-go maneuver and again this week when the spacecraft’s robot arm moved to put the samples inside the capsule.
\even though my heart breaks for the loss of sample, it turned out to be a pretty cool science experiment and we’re learning a lot,\ lauretta told reporters.
while collecting the samples, the container on the end of the robot arm pressed down 9 to 19 inches (24 to 48 centimeters) during the six seconds of contact, indicating a sandy and flaky interior beneath the rough surface, lauretta said.
the slow, tedious stowing operation took 36 hours. after each successful step, flight controllers cheered, saving the biggest and loudest response when the lid on the capsule finally was closed and latched, sealing the samples inside.
it will be september 2023 — seven years after osiris-rex rocketed from cape canaveral — before the samples arrive here.
rich in carbon, the solar-orbiting bennu is believed to hold the preserved building blocks of the solar system. scientists said the remnants can help explain how our solar system’s planets formed billions of years ago and how life on earth came to be. the samples also can help improve our odds they

Explanation:

Since no specific question is provided about this text, it's not possible to give a targeted answer. If you want to know about the scientific concepts (like elements/compounds in the context of the Bennu sample, or the space mission's scientific goals), or have a question about the text's content (like summarizing, analyzing a detail), please clarify your question. For example, if you want to know what the significance of the Bennu samples is, the answer would be related to studying solar system formation and the origin of life on Earth, as the text states the samples can help explain how planets formed and how life on Earth came to be, and also hold preserved building blocks of the solar system.
