In addition to the three manned missions, there was a rescue mission on standby that had a crew of two, but could take five back down.


How does one fit 5 astronauts in an Apollo command module? This answer suggests a second row of seats for such a flight. But where would the second row be placed? In the lower equipment bay, perhaps?


1 Answer 1


Seats were installed in the lower equipment bay, instead of some of the usual storage lockers. A Skylab rescue mission would take a few days at most, so the usual luxuries for a 2-week Apollo mission (like being able to go to the lower equipment bay for a little personal-hygiene privacy) could be foregone. The extra seats were mounted in the reverse direction from the main crew couches:

The rescue CSM had the usual Apollo service module (although, as with the other Skylab CSMs, the SPS tankage was reduced because it didn't need to make the large lunar-orbital-insertion and Earth-return maneuvers, and additional RCS fuel was carried for redundancy):

    $\begingroup$ One point that I always thought was interesting is that the shock absorbers on the upper seats had to be modified to have less travel. Apparently it would have been a rough landing. $\endgroup$
