Russian cosmonaut Sergei Prokopyev said that the mysterious hole in a Soyuz capsule stationed on the International Space Station was drilled from the inside, according to the Associated Press.
Prokopyev was one of two cosmonauts who had inspected the hole during an "unprecedented" spacewalk on December 1
Scientists found a pressure drop on the ISS on August 29 this year. They found that the source was a 2-millimeter hole in the Soyuz capsule and quickly filled it up with epoxy resin. NASA reported that the astronauts were never in danger.
Since then, photos of the hole showed it looked like a hole. The Russian authorities said it could come from "deliberate spoilage", but they have not made any direct allegations. Yury Borisov, Deputy Prime Minister of Russia for the defense and aerospace industry, vehemently denied the attempt "either" to make our cosmonauts or American astronauts "[compromise the reputation]," said the Russian state news agency RIA Novosti
Prokopyev and Russian The cosmonaut Oleg Kononenko inspected the hole in a complex spacewalk on Dec. 11, during which part of the capsule meteorite shield had to be removed.
There are not many other details available today – and it is unclear whether the hole was created in the earth or in space. Pablo De Leon, Professor of Extravehicular Activities and Space Suit Design at the Department of Space Research, University of North Dakota, Grand Forks, told us in September that microgravity would have made it extremely difficult to drill such a hole in space. In fact, Prokopyev said that further investigations are needed to determine when the hole was made.
While this may be a new development in history, this does not change much. We still do not know who made the hole and when, and the investigation continues. Prokopyev denies that the hole could have been drilled by an astronaut.
We contacted NASA for comment, and will continue to keep you informed about this story.
