A meeting between OSIRIS-REx and Bennu will mark the first NASA mission to collect material from the surface of an <\/span>asteroid<\/a>. This mission is also a labor of love for researchers around the globe who invested years of their lives into the historic mission.<\/p>\n

The Origins, Spectral Interpretation, Resource Identification, and Security\u2013Regolith Explorer (OSIRIS-REx) arrived at Bennu late in 2018, and has been studying the asteroid ever since.<\/p>\n

The <\/span>asteroid<\/a> containsome of the building blocks of life, making this mission vital in the search for answers to how life began on Earth, and \u2014 potentially \u2014 other worlds.<\/p>\n

\u201cOSIRIS-REx spectrometer data show absorptions (\u201cfingerprints\u201d) of complex organic molecules and carbonate minerals on Bennu\u2019s surface\u2026 The presence of organics on Bennu suggests that asteroids like Bennu may have brought organic molecules to Earth,\u201d researchers describe in an article published in the journal <\/span>Science<\/em><\/a>.<\/p>\n

Carbon and associated molecules were detected on Bennu prior to the arrival of <\/span>OSIRIS-REx<\/a>, and that mission will assist researchers searching for answers to the chemical makeup of that enigmatic body.<\/p>\n

\u201cBennu is likely rich in organic molecules, which are made of chains of carbon bonded with atoms of oxygen, hydrogen, and other elements in a chemical recipe that makes all known living things. Besides carbon, Bennu also might have another component important to life: water, which is trapped in the minerals that make up the asteroid,\u201d <\/span>NASA describes<\/a>.<\/p>\n

Launched in 2016, OSIRIS-REx searched the <\/span>asteroid<\/a> <\/span>for potential touchdown locations from September 4 to 27. The first sample collection attempt is scheduled for October 20, and the sample is due to arrive on Earth September 23, 2023.<\/p>\n

\u201cWe\u2019ve been working for over a decade toward the upcoming sampling attempt. It\u2019s such an exciting time. The spacecraft will send back data pretty quickly to let us know if the maneuver itself was successful, and it\u2019ll be exciting to see images from the sampling event, which should be sent back within a day,\u201d Joshua Emery, associate professor in NAU\u2019s Department of Astronomy and Planetary Science, stated.<\/p>\n

Bennu belongs to a class of asteroids know as rubble pile asteroids<\/a> <\/span>\u2014 which, as the name suggests, are loose amalgamations of smaller pieces, rather than one solid body.<\/p>\n

New findings from the OSIRIS-REx spacecraft suggest Bennu is stronger and denser in it\u2019s outer layers than inside, like a creme-filled chocolate egg. This finding came from studying minor fluctuations in the gravitational field of the asteroid.<\/p>\n

\u201cIf you can measure the gravity field with enough precision, that places hard constraints on where the mass is located, even if you can\u2019t see it directly,\u201d said <\/span>Andrew French<\/a>, at NASA\u2019s Jet Propulsion Laboratory (JPL)<\/p>\n

Bennu is rotating faster over time, pushing carbon-rich material from its core closer to the surface.<\/p>\n

This could be bad news for Bennu, as the finding suggests the <\/span>asteroid<\/a> <\/span>may fall apart within a million years.<\/p>\n
