		on his experience as he emerged from the craft into the daylight on the 
		Expedition 24 mission's second spacewalk, astronaut Doug Wheelock said 
		"the colors of the Earth just explode at you as you exit toward the 
		planet. Notice what looks like scorch marks on the hatch thermal cover, 
		the effect of vacuum and atomic oxygen on the threads and thread sealant 
		used on the thermal cover. The 'smell' of space follows suit, I've heard 
		it described like burnt cake or cookies, or like the smell of an 
		extinguished match." 
 Wheelock and fellow astronaut Tracy Caldwell Dyson completed the second 
		of three spacewalks to remove a failed ammonia coolant pump module on 
		the station's S1 truss on Wednesday, Aug. 11, 2010.
