The Indian Space Research Organization, ISRO, has stopped launching the lunar probe Chandraan-2 (Chandrayaan-2), which was scheduled to launch on July 15 (local time). The reason for the suspension was a technical problem, but the exact cause was not disclosed.
ISRO said at a press conference in June that it would launch a rocket equipped with an Indian lunar probe on July 15th. However, the countdown timer suddenly stopped 56 minutes 24 seconds before the scheduled launch time.
A technical snag was observed in launch vehicle system at 1 hour before the launch. As a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. Revised launch date will be announced later.

ISRO announced through its official Twitter account that it found a technical problem an hour before launch and decided to put the launch on hold as a precautionary measure. The launch schedule will be revealed again afterwards, but according to unconfirmed information obtained by Indian media, the launch is likely to be in August. In another interview, an official from the Defense Research and Development Organization of India expressed the view that the launch could be delayed for two to three months.
Indian authorities did not reveal why the launch of the rocket carrying the Chandraan 2 was stopped, but reports are likely that fuel leaked from the rocket engine. The GSLV-III rocket in which the problem was discovered is a purely Indian rocket developed by ISRO, and will be used for manned space flight missions in India scheduled for 2022 in addition to this mission.
