preserved within the dust and rocks of asteroid Bennu, we are unlocking a time capsule that offers us profound insights into the ori- gins of our solar sys- tem,” said Dante Lauretta, OSIRIS-REx principal investiga- tor, University of Arizona, Tucson. “The bounty of car- bon-rich material and the abundant presence of water- bearing clay miner- als are just the tip of the cosmic ice- berg. These discov- eries, made possible through years of dedicated collabora- tion and cutting- edge science, propel us on a journey to understand not only our celestial neighborhood but also the poten- tial for life’s beginnings. With each revelation from Bennu, we draw closer to unraveling the mysteries of our cosmic heritage.” For the next two years, the mission’s science team will continue charac- terizing the samples and conduct the analysis needed to meet the mis- sion’s science goals. NASA will pre- serve at least 70% of the sample at Johnson for further research by sci- entists worldwide, including future generations of scientists. As part of OSIRIS-REx’s science program, a co- hort of more than 200 scientists around the world will explore the regolith’s properties, including re- searchers from many U.S. institu- tions, NASA partners JAXA (Japan Aerospace Exploration Agency), CSA (Canadian Space Agency), and other scientists from around the world. Additional samples will also be loaned later this fall to the Smith- sonian Institution, Space Center Houston, and the University of Ari- zona for public display.  NOVEMBER-DECEMBER 2023 ﻣﺠﻠﺔ FreeAstronomy ﺎﻟﻌﺮ ﺔ 7 ﺖ ﻗﺎﻟــ داﻧﺘــﻲ ﻟﻮرﻳﺘــﺎ اﻟﺒﺎﺣـــﺚ اﻟﺮﺋـــ ﻴﴘﰲ ـ ﻣﴩوع أوﺳـﺎﻳﺮﴎﻛﺲ ﻣــﻦ ﺟﺎﻣﻌــﺔ أرﻳﺰوﻧــﺎ ﺗﻮﻛﺴﻮن :" ﺑﻴﻨﻤﺎ ﻧﺘﻌﻤﻖ ﰲ اﻷﴎار اﻟﻘﺪﻳﻤــــــﺔ ا ﺤﻔﻮﻇـﺔ داﺧـﻞ ﻏﺒـﺎر وﺻﺨﻮر اﻟﻜﻮﻳﻜـﺐ ﺑﻴﻨـﻮ ﻓﺈﻧﻨــﺎ ﻧ ﻔــﺘﺢ ﻛﺒﺴــﻮﻟﺔ زﻣﻨﻴــﺔ ﺗﻘــﺪم ﻟﻨــﺎ رؤى ﻋﻤﻴﻘــﺔ ﺣــﻮل أﺻــﻮل ﻧﻈﺎﻣﻨ ـﺎ اﻟﺸـ إن " . ﻤﴘـ وﻓ ــﺮة ا ــﻮاد اﻟﻐﻨﻴ ــﺔ ﺑـــﺎﻟﻜﺮﺑﻮن واﻟﻮﺟـــﻮد اﻟﻮﻓ ة ﻟﻠﻤﻌﺎدن اﻟﻄﻴﻨﻴـﺔ اﻟﺤﺎﻣﻠﺔ ﻟﻠﻤﺎء ﻫﻤﺎ ﻣﺠﺮد ﻗﻤﺔ ﺟﺒﻞ اﻟﺠﻠﻴﺪ اﻟﻜﻮﻧﻲ . إن ﻫﺬه اﻻﻛﺘﺸﺎﻓﺎت اﻟﺘﻲ أﺻﺒﺤﺖ ﻣﻤﻜﻨﺔ ﻣﻦ ﺧﻼل ﺳــﻨﻮات ﻣــﻦ اﻟ ﺘﻌــﺎون ا ﺘﻔﺎﻧﻲ واﻟﻌﻠﻮم ا ﺘﻄﻮرة ﺗــﺪﻓﻌﻨﺎ ﰲ رﺣﻠــﺔ ﻟﻔﻬــﻢ ﻟـــﻴﺲ ﻓﻘــﻂ ﺟﻮارﻧــﺎ ﻧﻲ ﻟ ﻮ ﺗﺪﻓﻌﻨﺎ ﰲ رﺣﻠـﺔ ﻟﻔﻬﻢ ﻟﻴﺲ ﻓﻘﻂ ﺟﻮارﻧﺎ اﻟﺴـﻤﺎوي وﻟﻜـﻦ أﻳﻀًﺎ اﺣﺘﻤﺎﻻت ﺑﺪاﻳﺎت اﻟﺤﻴﺎة . أﻳﻀًﺎ اﺣﺘﻤـﺎﻻت ﺑـﺪاﻳﺎت اﻟﺤﻴـﺎة وﻣـﻊ ﻛـﻞ اﻛﺘﺸﺎف ﻣﻦ ﻋﻴﻨﺎت اﻟﻜﻮﻳﻜﺐ ﺑﻴﻨﻮ ﻧﻘﱰب ﻣﻦ ﻛﺸﻒ أﴎار ﺗﺮاﺛﻨﺎ اﻟﻜﻮﻧﻲ . ﻛﺸﻒ أﴎار ﺗﺮاﺛﻨﺎ اﻟﻜﻮﻧﻲ . ﺧﻼل اﻟﻌـﺎﻣ ا ﻘﺒ ﻠ ﺳﻴﻮاﺻﻞ اﻟﻔﺮﻳـﻖ اﻟﻌﻠﻤـﻲ ﻟﻠﺒﻌﺜـﺔ ﺗﻮﺻﻴﻒ اﻟﻌﻴﻨﺎت وإﺟـﺮاء اﻟﺘﺤﻠﻴـﻞ اﻟـﻼزم ﻟﺘﺤﻘﻴﻖ اﻷﻫﺪاف اﻟﻌﻠﻤﻴﺔ ﻟﻠﺒﻌﺜﺔ . ﺳﺘﺤﺘﻔﻆ ﻧﺎﺳﺎ ﺑﻤﺎ ﻻ ﻳﻘﻞ ﻋـﻦ 70 % ﻣـﻦ اﻟﻌﻴﻨـﺔ ﰲ ﺟﻮﻧﺴﻮن ﻹﺟﺮاء ا ﺰﻳﺪ ﻣﻦ اﻷﺑﺤﺎث ﻣﻦ ﻗﺒﻞ اﻟﻌﻠﻤﺎء ﰲ ﺟﻤﻴﻊ أﻧﺤﺎء اﻟﻌﺎﻟﻢ ﺑﻤـﺎ ﰲ ذﻟـﻚ اﻷﺟﻴ ـﺎل اﻟﻘﺎدﻣ ـﺔ . ﻛﺠ ـﺰء ﻣ ـﻦ ﺑﺮﻧ ـﺎﻣﺞ أوﺳ ﺎﻳﺮس رﻛﺲ اﻟﻌﻠﻤﻲ ﺳ ﻴ ﻘﻮم أﻛﺜـﺮ ﻣـﻦ 200 ﻋــﺎﻟﻢ ﺣــﻮل اﻟﻌــﺎﻟﻢ ﺑﺎﺳﺘﻜﺸــﺎف ﺧﺼﺎﺋﺺ اﻟﻌﻴﻨﺎت ﺑﻤﺎ ﰲ ذﻟﻚ ﺑﺎﺣﺜﻮن ﻣـﻦ اﻟﻌﺪﻳﺪ ﻣﻦ ا ﺆﺳﺴﺎت اﻷﻣﺮﻳﻜﻴـﺔ وﴍﻛـﺎء ﻧﺎﺳـﺎ ﻣﺜ ـﻞ وﻛﺎﻟ ـﺔ اﺳﺘﻜﺸـﺎف اﻟﻔﻀـﺎء اﻟﻴﺎﺑﺎﻧﻴﺔ و وﻛﺎﻟﺔ اﻟﻔﻀﺎء اﻟﻜﻨﺪﻳﺔ وﻏ ﻫـ ﺎ ﻣﻦ اﻟﻌﻠﻤﺎء ﻣﻦ ﺟﻤﻴﻊ أﻧﺤﺎء اﻟﻌﺎﻟﻢ . ﺎً ﺳﻴﺘﻢ أﻳﻀ إﻋﺎرة ﻋﻴﻨﺎت إﺿﺎﻓﻴﺔ ﰲ وﻗـﺖ ﻻﺣـــﻖ ﻫـــﺬا اﻟﺨﺮﻳـــﻒ إﱃ ﻣﺆﺳﺴـــﺔ ﺳﻤﻴﺜﺴﻮﻧﻴﺎن وﻣﺮﻛﺰ اﻟﻔﻀﺎء ﰲ ﻫﻴﻮﺳـﺘﻦ وﺟﺎﻣﻌﺔ أرﻳﺰوﻧﺎ ﻟﻠﻌﺮض اﻟﻌﺎم . ﻟﻮر ﺘــﺎ ﺘﺤــﺪثداﻧــ ) ﻓــﻲاﻟﻮﺳــﻂ ( اﻟ ﺎﺣــﺚ اﻟﺮ ﺴــﻲﻓـــﻲﻣﺸــﺮوع اوﺳــﺎﻳﺮسرﻛــﺲ وأﺳـــﺘﺎذ ﻋﻠــﻮم اﻟ ﻮاﻛــﺐﻓــﻲ ﺟﺎﻣﻌـــﺔ ار ﺰوﻧـﺎ ــﮫ ﻋـﻦ اﻻﻛﺘﺸــﺎﻓﺎت اﻷوﻟــﻰﻣــﻦ ﻋ ﻨــﺔ ﻮ ﻜــﺐ ﺑ ﻨــﻮ ﻓــﻲﻣﺮﻛــﺰﺟﻮﻧﺴــﻮن ﻟﻠﻔﻀــﺎء اﻟﺘــﺎﺑﻊ ﺧــﻼلﻣــﺆﺗﻤﺮﺻـﺤﻔﻲأﻋﻠــﻦ ﻓ ﻟﻨﺎﺳﺎ . أﻋﻀﺎء اﻟﻠﺠ ﻨﺔ اﻵﺧﺮون، ﻣﻦ اﻟ ﺴﺎرﻫﻢ ﻟﻮريﺟﻠ ﻣﺪﻳﺮة ﻗﺴﻢﻋﻠﻮم اﻟ ﻮاﻛﺐﻓﻲﻣﺪﻳﺮ ﺔ اﻟﻤﻬﺎم اﻟﻌﻠﻤ ﺔ اﻟﺘﺎ ﻌـﺔ وﻣـــﺪﻳﺮ ﻧﺎﺋــﺐر ــ ﺲﺗﻨﻈــ ﻢ اوﺳــﺎﻳﺮسرﻛــﺲﻓﺮاﻧﺴــ ﺲﻣــﺎ ﻮﺑ ــﺎلﺟﻼﻓــ ﻟﻨﺎﺳــﺎ؛ ﺗﺤﻠﻴــﻞ ﻋ ﻨــﺔ أوﺳــﺎﻳﺮسرﻛــﺲ ﻘــﻮدﻩ داﻧ ﻧﺎﺳﺎ ﺑﻴﻞ ﻧ ﻠﺴﻮن . ﺗﻜﺒ ﺣ ﺔﺻﻐ ة ﻣﻦ اﻟﻌ ﻨﺔ ﺣ ﺚﺗﻜﺸﻒ اﻟ ﻘﻊ اﻟﺼﻐ ة اﻟﺴﺎﻃﻌﺔ ﻓﻲاﻟﺼﻮرة ﻋﻠﻰاﻟ ﻤ ﺗﺤﺖ ) ﺿﻮء اﻷﺷﻌﺔ ﻓﻮق اﻟ ﻨﻔﺴﺠ ﺔ ( ﻋﻦ وﺟﻮد ﻣﺮﻛ ﺎتﻋﻀﻮ ﺔ . ﻧﻮﻓﻤﺒﺮ - ﺩﻳﺴﻤﺒﺮ 2 0 2 3
