Hello all,
<div class=""><br class="">
</div>
<div class="">We’re excited to announce that next week’s planetary seminar will feature the return to MIT of Angel Mojarro from NASA Goddard. He will be joining to discuss his analysis of samples from asteroid Bennu and what it can tell us about cosmochemistry
and the origins of organic compounds. Please join us on Tuesday April 22 at 12:30 PM in 54-517 or on Zoom. Lunch will be provided and we encourage you to arrive a bit early to get food.</div>
<div class=""><br class="">
</div>
<div class="">Angel is available on Tuesday for one-on-one chats. You can sign up for a meeting <a href="https://docs.google.com/spreadsheets/d/1VCXWnjxa5vyREQe_a9GrI5DNeCouJBg62fi3fyJs8yg/edit?usp=sharing" class="">here</a>.</div>
<div class=""><br class="">
</div>
<div class="">Talk details and Zoom information are below. We hope to see you there!</div>

<div class=""><i class="">Organic Matter in the Solar System: Insights from Bennu Sample Analysis</i></div>
<div class=""><br class="">
</div>
<div class=""><b class="">Abstract</b><b class="">: </b>A longstanding question regarding the formation and evolution of the solar system concerns the potential sources and diversity of complex organic compounds that may have contributed to the origins of life
on the early Earth and perhaps elsewhere. One possibility is that exogenous delivery of organics synthesized within the early solar nebula may represent the most significant source of prebiotically relevant materials (e.g., amino acids, sugars, nucleobases). Therefore,
organic-rich asteroids and comets that have persisted with minimal alteration since their accretion may serve as time capsules of the primordial solar system to better understand our planetary and prebiotic origins. This is one of the reasons that NASA’s OSIRIS-REx
mission collected materials from the rare B-type carbonaceous asteroid Bennu, which were delivered to Earth on September 24th, 2023. We anticipate that this will enable an unprecedented study of remarkably ‘pristine’ samples from a well-characterized parent
body to unlock the earliest stages of cosmochemistry.</div>
