Chandrayaan-2 Highlights: ‘Bounced back with flying colours after technical snag’, says Isro chief

Chandrayaan-2 launch Highlights: India’s second moon mission was launched onboard Isro’s most powerful launcher GSLV-Mk III from Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota today.

By HT Correspondent | Jul 22, 2019 23:36 IST

India’s second mission to the moon — Chandrayaan-2 — was launched by Indian Space Research Organisation (Isro) from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, 2.43 pm on Monday, a week after the lift-off was aborted at the eleventh hour due to a technical snag.

Congratulating the team who made the mission possible, Isro chief Dr K Sivan said, “After a technical snag, we bounced back with flying colours.” In his address after the Chandrayaan-2 launch, Sivan said there will be 15 “very crucial manouvres” in the next one-and-half months before the satellite is brought around the moon.

Prime Minister Narendra Modi tweeted that Chandrayaan2 is unique because it will explore and perform studies on the south pole region of lunar terrain which is not explored and sampled by any past mission.

The lunar landing mission was rescheduled for July 22 after scientists corrected the glitch in the rocket.

Landing of Chandrayaan-2: Isro’s biggest challenge

Landing of Chandrayaan-2 is being called as Isro’s biggest challenge till now. The 15 minutes when the lander separates and before it soft lands on the moon have been called “terrifying moments” by the space agency which has never undertaken such a flight.

Chandrayaan-2 will attempt to soft-land Vikram and Pragyan in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70° south, ISRO has said.

2:19 pm IST

Key objectives of Chandrayaan-2

To demonstrate the ability to soft-land on the surface of the moon and to operate a rover on the surface is one of the key objectives of the mission. Here’s a look at the key objectives of Chandrayaan-2:

•To identify or to find out the minerals and indicators of hydroxyl and water molecules.

•To study the surface of the moon.

•To study the density of the electrons in the Moon’s ionosphere that is the uppermost part of the atmosphere that is ionised by radiation.

•The Orbiter will observe the lunar surface and relay communication between Earth and Chandrayaan 2’s Lander

•The lander is designed to execute India’s first soft landing on the lunar surface.

Chandrayaan-2 to perform 15 crucial manoeuvres

India’s lunar landing mission “Chandrayaan-2 will perform 15 crucial manoeuvres in the days to come, said Isro chief K Sivan on Sunday, adding “all the preparatory works regarding the launch have been completed and technical snags that developed in the first attempt have been rectified. “

2:01 pm IST

Why was south pole of Moon chosen for Chandrayaan-2 landing?

“Moon provides the best linkage to Earth’s early history. It offers an undisturbed historical record of the inner Solar system environment. Extensive mapping of lunar surface to study variations in lunar surface composition is essential to trace back the origin and evolution of the Moon, says the ISRO website.

1:49 pm IST

What will happen after the lift off?

About 16 minutes after Chandrayaan-2’s lift-off, the lander, GSLV MkIII, will inject the mission into 170 x 40400 kms Earth orbit.

From then onwards, the mission will witness a series of manoeuvres by scientists to carry out different phases of the mission.

Chandrayaan-2 to make India 4th country to soft land on lunar surface

1:22 pm IST

Why Isro named Chandrayaan- 2 lander ‘Vikram’

Chandrayaan 2’s 1.4 tonne lander has been named after Vikram A Sarabhai, the father of the space programme. It is designed to function for one lunar day, which is equivalent to about 14 Earth days. Vikram has the capability to communicate with IDSN at Byalalu near Bangalore, as well as with the Orbiter and Pragyan rover. The lander is designed to execute a soft landing on the lunar surface at a touchdown velocity of 2 metres per second.

The lander will carry with it a solar-powered rover named Pragyan — “wisdom” in Sanskrit —will roam as far as 500 metres away from the lander to study the composition of the Moon’s surface for one lunar day —the equivalent of 14 Earth days.

Helium is used in cryogenic engines that use oxygen and hydrogen as fuel, such as the Geosynchronous Satellite Launch Vehicle (GSLV) Mark III that will carry Chandrayaan-2, in pressuring the propellant tank to keep it from collapsing and to prevent the formation of bubbles.

How Chandrayaan-2 mission will stick to timeline despite delay

The July 15 launch was aborted at the eleventh hour due to a technical snag. Now, in order to catch up, the scientists have made adjustments that are necessary to keep in place a careful choreography of movements crucial to ensure the spacecraft does not overshoot the Moon, crash into surface or land at a spot not designated for the mission.

“These are minor adjustments to the orbit and will not affect the mission in any way. During the initial planning of the mission, some redundancies had been introduced to ensure that the mission could be completed even if there were any glitches,” said an Isro official, asking not to be named.
