After the landing by <a href="/wiki/Apollo_12" title="Apollo 12">Apollo 12</a>, Apollo 20, which would have been the final crewed mission to the Moon, was canceled to allow <a href="/wiki/Skylab" title="Skylab">Skylab</a> to launch as a "dry workshop" (assembled on the ground in an unused <a href="/wiki/S-IVB" title="S-IVB">S-IVB</a> <a href="/wiki/Saturn_IB" title="Saturn IB">Saturn IB</a> second stage).

(September 1966).</figcaption></figure> <p>In September 1962, <a href="/wiki/NASA" title="NASA">NASA</a> planned to make four crewed low-Earth-orbital test flights of partially equipped Block I <a href="/wiki/Apollo_Command/Service_Module" class="mw-redirect" title="Apollo Command/Service Module">Command/Service Modules</a> (CSM) using the <a href="/wiki/Saturn_I" title="Saturn I">Saturn I</a> launch vehicle, designated SA-11 through SA-14, in 1965 and 1966. However, the limited payload capacity of the Saturn I compared to the uprated <a href="/wiki/Saturn_IB" title="Saturn IB">Saturn IB</a> would have severely limited the systems carried, and thus the testing value of these flights. Therefore, NASA canceled these flights in October 1963,<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> and replaced them with two crewed Saturn IB missions, designated AS-204 and AS-205. These would be followed by the first uncrewed flight of the <a href="/wiki/Apollo_Lunar_Module" title="Apollo Lunar Module">Lunar Module</a> (LM) on AS-206, then the third crewed mission, designated AS-207/208, would use AS-207 to launch the crew in an improved Block II CSM, which would rendezvous and dock with the LM launched uncrewed on AS-208. </p><p>The crew selected on March 21, 1966, for AS-204 consisted of Command Pilot <a href="/wiki/Gus_Grissom" title="Gus Grissom">Virgil "Gus" Grissom</a>, Senior Pilot <a href="/wiki/Ed_White_(astronaut)" title="Ed White (astronaut)">Ed White</a>, and Pilot <a href="/wiki/Roger_Chaffee" class="mw-redirect" title="Roger Chaffee">Roger Chaffee</a>, who named their mission <a href="/wiki/Apollo_1" title="Apollo 1">Apollo 1</a>. AS-205 was to be named Apollo 2, and AS-207/208 would be Apollo 3.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The AS-205 crew were <a href="/wiki/Wally_Schirra" title="Wally Schirra">Wally Schirra</a>, <a href="/wiki/Donn_Eisele" class="mw-redirect" title="Donn Eisele">Donn Eisele</a> and <a href="/wiki/Walter_Cunningham" title="Walter Cunningham">Walter Cunningham</a>. However, AS-205 was later deemed unnecessary and officially canceled on December 22, 1966. </p><p>Schirra's crew then became the backup for Grissom's crew, and the crewed LM mission became the second crewed mission, redesignated AS-205/208 and crewed by the original backup for Grissom's crew: Command Pilot <a href="/wiki/Jim_McDivitt" class="mw-redirect" title="Jim McDivitt">Jim McDivitt</a>, CSM Pilot <a href="/wiki/David_Scott" title="David Scott">David Scott</a> and LM Pilot <a href="/wiki/Rusty_Schweickart" title="Rusty Schweickart">Rusty Schweickart</a>. They immediately began their training in the first Block II Command Module CM-101, as Grissom's crew were preparing for a February 1967 launch. </p><p>Then, on January 27, 1967, Grissom, White, and Chaffee were killed in a flash fire in their spacecraft cabin during a test on the launch pad, interrupting the program for 19 months to identify and fix the root causes of numerous safety problems. This forced cancellation of plans to fly any crewed Block I spacecraft, and effectively forced a "reboot" of all crewed mission plans. </p> <div class="mw-heading mw-heading2"><h2 id="Development_missions_after_Apollo_1_fire">Development missions after Apollo 1 fire</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Canceled_Apollo_missions&action=edit&section=2" title="Edit section: Development missions after Apollo 1 fire"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1236090951">.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}@media print{body.ns-0 .mw-parser-output .hatnote{display:none!important}}</style><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/List_of_Apollo_missions" title="List of Apollo missions">List of Apollo missions</a></div> <p>In September 1967, NASA created a list of remaining mission types necessary to achieve the first crewed lunar landing, each designated by a letter A through G, where G would be the first crewed landing.
