In honor of the planned spacewalk, the astronauts’ fifth day in space began with “The Stroll” by 1950s band The Gry na pieniądze Sobota Diamonds as their wakeup music. After they both donned their helmets to begin the four-hour prebreathe with pure oxygen to rid their blood of nitrogen, Allen’s suit fan came on and then shut off. Cycling the fan led to the same result. The astronauts and Mission Control began troubleshooting the problem, at first believing water trapped on the fan might be the problem. Without a working fan, Allen began to overheat so he removed his suit. As troubleshooting continued on Allen’s suit, Mission Control called up an alternate plan to have Lenoir begin his prebreathe and then conduct a solo test of his suit with the airlock depressurized but without exiting out to the payload bay.

As troubleshooting continued on Allen’s suit, Mission Control called up an alternate plan to have Lenoir begin his prebreathe and then conduct a solo test of his suit with the airlock depressurized but without exiting out to the payload bay. When Lenoir conducted a leak check of his suit, it only reached 3.8 pounds per square inch (psi) instead of the required 4.3 psi. Without a properly working pressure regulator in Lenoir’s suit, Flight Director Holloway decided to cancel the spacewalk – it would have to await a later shuttle mission. Lenoir and Allen, with Overmyer’s help, continued troubleshooting both suits, including pressurizing Allen’s suit without him in it to see if it could hold the required 4.3 psi. It eventually did, but without a working fan it still could not support the required prebreathe protocol. One final attempt had Lenoir put his suit back on and depressurize the airlock from 14.7 psi to 9 psi to see if that would fix the regulator, but without success. Hazard Pojedynczy.
