(August 22, 2023)\"><\/a>Chandrayaan-3 is mostly a technology demonstration\/test, but includes several science payloads.<\/p>\n\n\n\n<p>ISRO has upgraded their Vikram lander since the Chandrayaan-2 mission, so there&#8217;s a good chance for a successful touch down near the Moon&#8217;s south pole. The next step will be deploying and testing ISRO&#8217;s Lunar rover, Pragyan.<\/p>\n\n\n\n<p>I <strong>think<\/strong> those are their names, but ISRO used the same names for its Chandrayaan-2 mission, back in 2019.<\/p>\n\n\n\n<p>So it&#8217;s possible that Vikram and Pragyan are series names, like &#8220;Mustang&#8221; for a line of Ford sports cars. Or should that be nameplate? And I&#8217;ve long since drifted off-topic.<\/p>\n\n\n\n<p>I plan on taking a longer look at the Chandrayaan-3 mission in Saturday&#8217;s post.<\/p>\n\n\n\n<p>Including, if I can find more material, something about what ISRO calls the Lander Hazard Detection &amp; Avoidance Camera and Processing Algorithm and an NGC (Navigation, Guidance &amp; Control) system.<\/p>\n\n\n\n<p>In non-geek-speak, the Chandrayaan-3 mission has a smart lander.<\/p>\n\n\n\n<p>The Times of India has a pretty good article about what the Vikram lander will be doing during descent and landing.<\/p>\n\n\n\n<p>I put a link to that, and other resources, in this post&#8217;s footnote.<sup><a href=\"https:\/\/brendans-island.com\/catholic-citizen\/indias-goal-chandrayaan-3-on-the-moon\/#1\">1<\/a><\/sup><\/p>\n\n\n\n<p>Whatever happens today, the Chandrayaan-3 mission has already had significant success.
