The competition heats up: Roscosmos is planning this week to award a research grant for test flying components on ISS of a nuclear rocket engine Russia has been developing since 2009.
The small amount of money, about $4 million, likely means this will not be a full scale model. Moreover, that this research grant is only being awarded now, seven years after the program began, suggests to me that work is going very slowly. While the delays might be technical, I suspect it is more likely because of the underlying corruption that percolates throughout the government-run Russian system. The project is being slow-walked, so that the funds will be available to the one Russian company that is doing the work for as long as possible.
