S69-25878 (23 Feb. 1969) --- Astronaut <a href="https://en.wikipedia.org/wiki/Rusty_Schweickart" class="extiw" title="en:Rusty Schweickart">Russell L. Schweickart</a>, lunar module pilot of the <a href="https://en.wikipedia.org/wiki/Apollo_9" class="extiw" title="en:Apollo 9">Apollo 9</a> prime crew, wears the <a href="https://en.wikipedia.org/wiki/Extravehicular_Mobility_Unit" class="extiw" title="en:Extravehicular Mobility Unit">Extravehicular Mobility Unit</a> (EMU) which he will use during his scheduled Apollo 9 extravehicular activity. In addition to the space suit and bubble helmet, the EMU also includes a Portable Life Support System back pack, an Oxygen Purge System (seen atop the PLSS), and a Remote Control Unit on his chest. This equipment will be completely independent of the spacecraft during Schweickart's EVA. He will be secured only by a tether line. When this photograph was taken, Schweickart was suited to participate in an Apollo 9 Countdown Demonstration Test.
