| During Seven-Hour Spacewalk, Russian Astronauts Gather Clues to Orbital Mystery | During Seven-Hour Spacewalk, Russian Astronauts Gather Clues to Orbital Mystery |

| Soon they began slashing with vigor through the outer insulation, with flurries of debris flying into space. Other times, they used what looked like hedge shears to cut first through the insulation that was the spacecraft’s outer layer, and then into an aluminum micrometeoroid shield beneath that. | |
| “Don't forget to be careful,” Russian flight controllers in Moscow repeatedly warned the astronauts, protected from the vacuum of space by nothing but a spacesuit. “And don't forget about the sharp edges. That's our main concern.” | “Don't forget to be careful,” Russian flight controllers in Moscow repeatedly warned the astronauts, protected from the vacuum of space by nothing but a spacesuit. “And don't forget about the sharp edges.

| Finally, the astronauts, Oleg Kononenko and Sergey Prokopyev, found what they were looking for: a tiny, sealed hole in the spacecraft’s hull. | Finally, the astronauts, Oleg Kononenko and Sergey Prokopyev, found what they were looking for: a tiny, sealed hole in the spacecraft’s hull. |
| They sought out this puncture because they were seeking clues to who drilled that circular hole in a Soyuz craft that is currently docked at the space station. The hole caused a small air leak at the space station in August. Though quickly sealed, it roiled space relations between the United States and Russia as Russian media speculated that a NASA astronaut had deliberately sabotaged the station. | They sought out this puncture because they were seeking clues to who drilled that circular hole in a Soyuz craft that is currently docked at the space station.

| The spacewalk, the 213th at the station, began at 10:59 a.m. Eastern time and lasted seven hours, 45 minutes. | The spacewalk, the 213th at the station, began at 10:59 a.m. Eastern time and lasted seven hours, 45 minutes. |
| The Soyuz spacecraft will return to Earth later this month. The hole and the additional damage caused by Tuesday’s investigation will pose no danger to the descending astronauts. That part of the spacecraft will be discarded before re-entry. | The Soyuz spacecraft will return to Earth later this month.

| During the spacewalk, the astronauts took pictures of the hole and collected residues that may help solve the orbital whodunit. | During the spacewalk, the astronauts took pictures of the hole and collected residues that may help solve the orbital whodunit. |
| The trouble started on Aug. 29, when instruments aboard the space station noted a slight drop in air pressure. It was not an immediate risk to the crew of six astronauts, who were asleep at the time. Flight controllers on the ground did not even wake them up. | The trouble started on Aug. 29, when instruments aboard the space station noted a slight drop in air pressure.

| The next day, astronauts found the leak — a two-millimeter-wide puncture in the Soyuz — and sealed it. At first, space experts speculated that the spacecraft had been punctured by a micrometeoroid — a high-speed speck of rock or debris. | The next day, astronauts found the leak — a two-millimeter-wide puncture in the Soyuz — and sealed it.

| “It was done by a human hand,” Dmitry Rogozin, the head of Roscosmos, the Russian space agency, told the TASS news agency. “There are traces of a drill sliding along the surface. We don’t reject any theories.” | “It was done by a human hand,” Dmitry Rogozin, the head of Roscosmos, the Russian space agency, told the TASS news agency. “There are traces of a drill sliding along the surface.

| Mr. Rogozin said it could have been a manufacturing error, but he also raised the specter of sabotage, possibly even by one of the astronauts. | Mr. Rogozin said it could have been a manufacturing error, but he also raised the specter of sabotage, possibly even by one of the astronauts. |

| Whether Tuesday’s forensic spacewalk will settle the case — and ease the disquiet between the two space powers — remains to be seen. The samples collected by the astronauts and the pictures they took will be returned to Earth for more examination by Russian investigators. | Whether Tuesday’s forensic spacewalk will settle the case — and ease the disquiet between the two space powers — remains to be seen.
