"The launch is scheduled for September 27, with an alternate date of October 2," NASA said in a statement.
It is noted that the postponement of the launch date is associated with the need to conduct a number of tests.
Earlier, the launch of the rocket, scheduled for September 3, was postponed due to problems with refueling.
On August 29, NASA also delayed the launch of the launch vehicle due to a malfunction in the engines.
