However, the impact of the upper stage &#8216;bullet&#8217; showed up nicely on LCROSS&#8217;s infra-red camera:<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/all-geo.org\/highlyallochthonous\/wp-content\/uploads\/2010\/07\/LCROSS_impact_IR.jpg\" width=\"400\" height=\"304\" alt=\"LCROSS infrared image showing flash from impact of Centaur stage\"\/><br \/><b>image courtesy of <a href=http:\/\/www.planetary.org\/blog\/article\/00002159\/>Emily Lakdawalla at the Planetary Society Blog<\/a><\/b><\/p>\n<p><a href=http:\/\/www.planetary.org\/blog\/article\/00002159>Emily also reports<\/a> that the LCROSS spectrometer definitely registered <em>something<\/em> above the impact site, although we&#8217;ll have to wait a bit before we hear whether that something included the hoped-for water.<br \/>\nThinking about it, seeing anything in the visual spectrum was was always going to be tricky:  the impact was deliberately aimed at a spot in deep shadow , so debris would have to be thrown up pretty high for sunlight to illuminate it. Indeed, judging from what I caught of the post-mission press conference, none of the scientists leading the mission seemed particularly surprised by the lack of visual fireworks. I suppose that we were all somewhat spoilt by the pictures from <a href=http:\/\/www.nasa.gov\/mission_pages\/deepimpact\/main\/index.html>Deep Impact<\/a>.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/all-geo.org\/highlyallochthonous\/wp-content\/uploads\/2010\/07\/PIA02133.jpg\" width=\"400\" height=\"318\" alt=\"flash from Deep Impact impact\"\/><br \/><b>Image from <a href=http:\/\/photojournal.jpl.nasa.gov\/catalog\/PIA02133>NASA<\/a><\/b><\/p>\n<p>On the other hand, none of the publicity about this mission over the last few days seems to have gone out of it&#8217;s way to downplay expectations of a big kaboom (I was a little disappointed, and I was only expecting something on the lines of a little-to-middling puff). Public engagement is obviously a good thing, but engaging people labouring under a false assumption could easily backfire.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At least one camera was looking at the impact site in the right wavelength&#8230;<br \/>\n <a href=\"https:\/\/all-geo.org\/highlyallochthonous\/2009\/10\/lcross-the-aftermath\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,15],"tags":[163],"class_list":["post-3531","post","type-post","status-publish","format-standard","hentry","category-geology","category-planets","tag-lcross-moon-water-impact"],"_links":{"self":[{"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/posts\/3531","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/comments?post=3531"}],"version-history":[{"count":0,"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/posts\/3531\/revisions"}],"wp:attachment":[{"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/media?parent=3531"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/categories?post=3531"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/all-geo.org\/highlyallochthonous\/wp-json\/wp\/v2\/tags?post=3531"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
