New Delhi, July 16: This was not an amusing moment for India when the world was watching with bated breath as India got ready to mark its signature on the Moon. The launch of Chandrayaan-2 launch was called off due to a technical snag on Monday. The Moon is yet out of reach, as of now.
"It is not possible to make the launch within the launch window. The revised launch schedule will be announced later," the mission director announced. Minutes before making this announcement, the officials put on hold the countdown. Here is the chronology of events as it happened in 10 Point:
1. "A technical snag was observed in launch vehicle system at T-56 minute. As a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. Revised launch date will be announced later," the Indian Space Research Organization (ISRO) announced in an official statement.
2. ISRO officials said, the launch was called off due to technical problems in the fuel conductor. In a shocking development, the mission was put on hold with just 56 minutes and 24 seconds to go. "The technical snag was noticed during the cryogenic fuel was being loaded. We have to approach the vehicle to assess the problem. First we have to empty the fuel loaded in the rocket, then the rocket will be taken back for further investigation," ISRO source said.
"This process will take 10 days after that only we can decide on the launch schedule," the source further added.
3. Aptly named Bahubali, as it was on a mammoth mission of carrying a heavy Chandrayaan 2 spacecraft, the 20-hour countdown for the July 15 early morning was progressing smoothly.
4. Do you know why standing at about 44 meters tall, the 640-tonne rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) is nicknamed 'Bahubali'? This is because just like the hero in the hit film by the same name lifted a heavy 'lingam', the rocket is also supposed to carry the 3.8 tonne Chandrayaan-2 spacecraft.
5. The Rs 375 crore GSLV-Mk III rocket was expected to sling the Rs 603 crore Chandrayaan-2 into an Earth parking 170x40,400 km orbit. The total cost of the project is around Rs 1000 crore.
6. It will be a long journey to the moon for the Chandrayaan-2 spacecraft carrying a lander called Vikram and a rover known as Pragyan. The journey is quite a long one as the distance between the Earth and the moon is about 3.844 lakh km.
7. The earlier calculation was that on September 6, the lander Vikram was expected to make a soft landing on the moon and then the rover Pragyan will roll out to carry out in-situ experiments. As the countdown began, the rocket and the spacecraft's systems underwent ample checks and fuel will be filled to power the rocket engines.
8. According to ISRO, filling of the liquid fuel in the Liquid Core Stage was completed on Sunday itself. GSLV-Mk III is designed to carry 4 tonne class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tonne to Low Earth Orbit (LEO), which is about twice the capability of GSLV Mk II.
9. ISRO has done that earlier also as to date, ISRO has sent up three GSLV-Mk III rockets. The first was on December 18, 2014, which carried the Crew Module Atmospheric Reentry Experiment. Then the second and third GSLV-Mk III went up on February 5, 2017 and November 14, 2018, carrying communication satellites GSAT-19 and GSAT-29, respectively.
10. It needs to be mentioned that GSLV-Mk III will also be used for India's manned space mission slated in 2022. As of now, all eyes are on ISRO as the new date and time will be announced to carry on with the unfinished job of launching the ambitious Chandrayaan 2.
