Chandrayaan 2 launch date and time: ISRO announces revised date for launch on 22 July

Chandrayaan 2, July 15, 2019, launched the second mission of India for the closed moon due to technical failure, on Monday 22 July 2019, 2.43 pm IST, ISRO has announced in a tweet today. In a dramatic and anti-climate turnaround of events, the Indian Space and Research Organization (ISRO) launched the much anticipated Chandrayaan 2 on July 15, 2.5 minutes from its scheduled liftoff, 56 minutes earlier.

After the launch on July 15, the ISRO tweet said that the mission was canceled due to a "technical blockade" but it did not specify anything nor did ISRO Associate Director A lot of said when you read it, a small announcement at 2.40 is almost word-of-mouth saying what was said in earlier tweets.

Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk-III), the heaviest and most capable launch vehicle of ISRO, will launch the Chandan 2 mission. Made by indigenously developed by ISRO, it uses liquid hydrogen and oxygen as fuel. A ISRO expert told to TOI, although in an informal capacity, that after launching helium in the tank, the launch was discontinued due to a drop in pressure. Pressure drop indicated a leakage in the fuel tank.

Another source told The Economic Times that the fall of the rocket was detected in the upper phase. "After filling liquid oxygen (oxidizer) and liquid hydrogen (fuel), helium was being filled. The process is to press the bottle of Helium 350 times and control the output to 50 times. After filling the helium, we found that The pressure was falling, indicating that there was a leak. The team has yet to pinpoint the precise location of the leak in the gas bottle, there may be many leaks, "the scientist said.

The similar leak happened even before the Chandrayaan-1 mission, the former head of ISRO, Madhavan Nair said in an interview with Mai Nation, but it was corrected and the mission was successful. They also said that these "glitches were not unusual" and that "one was saved from the devastation because the discrepancy was detected in time."
