A new adapter block for the homegrown space rocket arrived from Russia Saturday, setting the rocket on course for its third and final launch attempt, the Ministry of Education, Science and Technology said Sunday.

The new component replaces the faulty Russian-made adapter block that caused the attempt to be delayed.

The adapter block contains inlets for liquid fuel and helium gas and connects the launch pad with the first-stage booster.

The launch will now be possible after Nov. 26. The ministry is to set a new timeframe this week.

Earlier, the ministry set the launch window between Nov. 9 and 24.
