NASA highlights that rather than giving greater creditability to this blaming game, the most important aim must be to correct the manufacturing defect.
ISS commander Feustel has called the suggestion that the crew was somehow involved "embarrassing" and NASA on Wednesday expressed doubts over the theory that the hole was the result of sabotage.
NASA officials have said they are waiting for a final report from their Russian counterparts before making any conclusions. NASA said that this issue is completely separate which won't affect the future research.
In a concise explanation issued from its Washington headquarters, NASA stressed that Dimitri Rogozin, general chief of the Russian space agency Roscosmos, had out in the open comments this week ruled out a manufacturing defect as the reason. She also said that the reason behind this hole can be explained after completing the full investigation.
A NASA astronaut and a Russian cosmonaut are due to launch next week to join three astronauts who remain in the orbit.
Both Feustel and Arnold participated in dozens of educational downlink events while in space, as part of NASA's Year of Education on Station, reaching more than 2 lakh students in 29 states, the statement said.
Administrator Bridenstine is scheduled to attend the launch and plans to meet with Mr. Rogozin.
ISRO scientists and engineers have been working on the Gaganyaan spacecraft for the mission.
Previously, Rogozin - who once oversaw the space industry as deputy prime minister - admitted it had become hard to work with NASA.
"Problems with NASA, of course, have appeared, but not through the fault of NASA, but through the fault of those American circles outside of NASA", he said.
"Americans have this thing, the X-37". 'We don't understand its purposes.
