Russia’s state-run space corporation Roscosmos has not received an official notification from NASA yet the visit of its chief Dmitry Rogozin to the United States has been postponed, the corporation’s spokesman Vladimir Ustimenko told.

Axar.az reports citing Russian media.

"No, we haven’t received anything," he replied to the question.

Earlier, NASA said in a statement it had informed the Russian side Rogozin’s visit to the United States had to be postponed. Also, the agency said no new date for the visit had been set yet. For the time being there has been no reply from NASA to a question from TASS about the reasons for the decision.

NASA’s spokeswoman Megan Powers said on Wednesday NASA was pushing ahead with preparations for Rogozin’s visit to the United States despite criticism in Washington. Earlier, a number of US officials and legislators opposed plans for Rogozin’s visit to the United States. NASA Administrator Jim Bridenstine told TASS in an interview last October he would like Rogozin to speak at Rice University (Houston, Texas) during his visit to the United States.

He also declared that the Trump Administration had made a decision to pause sanctions against Rogozin, thus enabling the head of the Russian space agency to pay a visit to the United States at NASA’s invitation. Rogozin has been under US sanctions since 2014 over the situation in Ukraine.
