\"It was awesome,\" Barron said about the first spacewalk of her career.

The spacewalk was scheduled for Tuesday morning but was delayed hours before the stipulated start time after NASA got a \"debris notification.\"

The source of the debris has not been confirmed yet.

This spacewalk marked the 245th spacewalk for NASA and was a part of Expedition 66, a seven-member crew that will be in space till March 2022. It was Marshburn's fifth spacewalk, NASA said.
