That stage burned for 2 minutes 48 seconds and pushed the whole thing up about 61 kilometers (~38 miles) into the sky. After it fell away the {{w|S-II}} stage was activated. It used 5 {{w|J-2 (rocket engine)|J-2}} engines in the same configuration as the F-1s, and burned {{w|liquid hydrogen}} mixed with {{w|liquid oxygen}} for 6 minutes 35 seconds pushing the astronauts up to 184 kilometers (114.5 miles). The third stage ({{w|S-IVB}}) was a single J-2 engine burning liquid hydrogen and liquid oxygen. This stage was used in two parts, the first was to put the spacecraft into a stable orbit around Earth to perform a systems check and make sure the craft will be safe for going to the moon. This would usually take three orbits around Earth. As they came around the Earth they would burn the second part of the fuel, which is called a {{w|trans-lunar injection}} which put them on course for the moon. The first burn took 2 minutes 45 seconds, which put them in orbit 185 kilometers (115 miles) high.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background: #eee; color:black; font-size: smaller;&quot;&gt;&lt;div&gt;This comic is a diagram of the {{w|Saturn V}} rocket, &amp;quot;Saturn&amp;quot; isn't a very common word apparently, and neither is rocket, so [[Randall]] decided to use &amp;quot;Up Goer&amp;quot; which is a fair approximation of a craft designed to lift a payload from the earth to space.
