Launch - Apollo 9 - KSC

S69-25878 (23 Feb. 1969) --- Astronaut Russell L. Schweickart, lunar module pilot of the Apollo 9 prime crew, wears the Extravehicular Mobility Unit (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.
