As Cassidy swapped out a big battery pack weighing 428 kilos (194 kilograms) on the outdoors of the Worldwide Area Station, a small mirror connected to his spacesuit broke off and floated away, CNN reported Friday.
Such mirrors are connected to the wrist to assist astronauts see electrical elements on a spacesuit and to see into any blind spots that may happen. The mirrors measure 5 by three inches (7 by 12 centimeters) and weigh one-tenth of a pound (50 grams).
Except for the mirror mishap, Cassidy and fellow NASA astronaut Robert Behnken “accomplished all of the scheduled work on their first of 4 spacewalks to interchange batteries that present energy for the area station’s photo voltaic arrays, in addition to preliminary duties initially deliberate for the second scheduled spacewalk subsequent Wednesday,” NASA mentioned in a weblog put up Friday.
The 2 astronauts changed the current nickel-hydrogen batteries with new lithium-ion batteries. The brand new batteries retailer power generated by the station’s photo voltaic arrays to supply energy to the microgravity laboratory when the station is not in daylight.
Friday’s spacewalk lasted for six hours and seven minutes. Cassidy and Behnken are scheduled to do extra duties on a second spacewalk on July 1.
NASA did not instantly reply to a request for remark.
