He discovered the fossil Lucy in Ethiopia 50 years ago; the spacecraft is named after the famous human ancestor.<\/p>\n<p>NASA&#8217;s Lucy will venture as close as 596 miles to this asteroid, an estimated 2 \u00bd miles in length but much shorter in width. Scientists should have a better idea of its size and shape following the brief visit. The spacecraft will zoom by at more than 30,000 mph.<\/p>\n<p>The asteroid is among countless fragments believed to have resulted from a major collision 150 million years ago.<\/p>\n<p>&#8220;It&#8217;s not going to be a basic potato. We already know that,&#8221; said lead scientist Hal Levison of Southwest Research Institute.<\/p>\n<p>Rather, Levison said the asteroid may resemble a bowling pin or even a snowman like Arrokoth, the Kuiper Belt object visited by NASA&#8217;s New Horizons spacecraft in 2019. The other possibility is that there are two elongated but separate asteroids far apart.<\/p>\n<p>&#8220;We don&#8217;t know what to expect. That&#8217;s what makes this so cool,&#8221; he said.<\/p>\n<p>There will be no communications with Lucy during the flyby as the spacecraft turns its antenna away from Earth in order to track the asteroid. Levison expects to have most of the science data within a day.<\/p>\n<p>Unlike its first flyby, Lucy will stop tracking Donaldjohanson 40 seconds before its closest approach to protect its instruments from sunlight, NASA said.<\/p>\n<p>&#8220;If you were sitting on the asteroid watching the Lucy spacecraft approaching, you would have to shield your eyes staring at the sun while waiting for Lucy to emerge from the glare. After Lucy passes the asteroid, the positions will be reversed, so we have to shield the instruments in the same way,&#8221; Michael Vincent of Southwest Research Institute (SwRI) said in a <a href=\"https:\/\/www.nasa.gov\/missions\/lucy\/nasas-lucy-spacecraft-prepares-second-asteroid-encounter\/\" target=\"_blank\" rel=\"nofollow noopener\">statement<\/a>.\u00a0<\/p>\n<figure class=\"embed embed--type-image is-image embed--float-none embed--size-medium\">\n<p>      <span class=\"img embed__content\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2023\/11\/02\/ccb72b48-2891-4ab6-9a3e-4033eeccef29\/thumbnail\/620x400\/78f3df76c28a6eb713a1cc1c84b2f8d5\/nasa-asteroid-lucy.jpg?v=8e9dede207b29c97b32974c53e32aabc#\" alt=\"nasa-asteroid-lucy.jpg \" height=\"400\" width=\"620\" class=\" lazyload\" srcset=\"https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2023\/11\/02\/ccb72b48-2891-4ab6-9a3e-4033eeccef29\/thumbnail\/620x400\/78f3df76c28a6eb713a1cc1c84b2f8d5\/nasa-asteroid-lucy.jpg?v=8e9dede207b29c97b32974c53e32aabc 1x, https:\/\/assets1.cbsnewsstatic.com\/hub\/i\/r\/2023\/11\/02\/ccb72b48-2891-4ab6-9a3e-4033eeccef29\/thumbnail\/1240x800\/5fafa330042b14a8e77c6cc38bb3d565\/nasa-asteroid-lucy.jpg?v=8e9dede207b29c97b32974c53e32aabc 2x\" loading=\"lazy\"\/><\/span><figcaption class=\"embed__caption-container\">\n<p>                  <span class=\"embed__caption\">This image shows the &#8220;moonrise&#8221; of the satellite as it emerges from behind asteroid Dinkinesh, one of the most detailed images returned by NASA&#8217;s Lucy spacecraft during its flyby, on Nov. 1, 2023, from a range of approximately 270 miles.<\/span><\/p>\n<p>                  <span class=\"embed__credit\"><\/p>\n<p>                NASA\/Goddard\/SwRI\/Johns Hopkins APL\/NOAO<\/p>\n<p>                          <\/span><br \/>\n              <\/figcaption><\/figure>\n<p>Lucy&#8217;s next stop &#8211; &#8220;the main event,&#8221; as Levison calls it &#8211; will be the Trojan asteroids that share Jupiter&#8217;s orbit around the sun. Swarms of Trojans precede and follow the solar system&#8217;s largest planet as it circles the sun. Lucy will visit eight of them from 2027 through 2033, some of them in pairs of two.<\/p>\n<p><a href=\"https:\/\/science.nasa.gov\/mission\/lucy\/\" target=\"_blank\" rel=\"nofollow noopener\">The spacecraft is named\u00a0<\/a>after the 3.2 million-year-old skeletal remains of a human ancestor found in Ethiopia, which got its name from the 1967 Beatles song &#8220;Lucy in the Sky with Diamonds.&#8221; That prompted NASA to launch the spacecraft into space with band members&#8217; lyrics and other luminaries&#8217; words of wisdom imprinted on a plaque.
