HOUSTON, Feb. 16 (UPI) -- NASA says two astronauts upgraded science facilities for studying the sun during a seven-hour spacewalk Friday outside the shuttle Atlantis.
Rex Walheim and Stan Love bolted two packages for solar experiments onto the outside of the International Space Station and examined a dent in the station's skin, USA Today reported Saturday.
NASA is trying to determine whether the dent, located on a handrail near the door, is responsible for a puzzling series of snags in astronauts' spacesuits during the last 18 months. None of the astronauts were injured, but NASA officials feared a deep cut could allow air to leak from their suits, USA Today said.
"It is a little bit rough. I can feel it snagging," Walheim said in describing the dent to Mission Control. Walheim and Love are scheduled to return to Earth aboard Atlantis Wednesday.
