2. •Chandrayaan-2, India’s 2nd moon mission (after
Chandrayaan-1, 2008) was successfully launched on
22nd July at 2.43 pm by GSLV-MkIII-M1
(Geosynchronous Satellite Launch V
ehicle Mark III)
from Second Launch Pad at Satish Dhawan Space
Center Sriharikota (Andhra Pradesh).
•Main aim is to improve our understanding about the
Moon discoveries, latest inventions that will benefit
India.
•It will also provide detailed information of moon’s
topography and atmosphere leading to a better
understanding of Moon.
3. •With a total mission mass of 3.8 tonnes, the
entire project is set to cost Rs 978 crore.
•Rs 603 crore for the spacecraft and Rs 375
crore for the GSL
V Mk-III.
•Chandrayaan-2 consists of an orbiter, a
lander (Vikram), and a rover (Pragyan).
•Chandrayaan 2 will be India’s first
interplanetary mission to be steered by two
women, project director M V
anitha and mission
director Ritu Karidhal.
4. On 15th July, The launch was called off due to technical
problems in the fuel conductor.
The countdown for the launch of Chandrayaan-2, on board
the GSL
V Mk-III rocket, was scheduled for
2.51 am.
It was stopped 56 minutes and 24 seconds before lift-off at
1.55 am, following an announcement from the Mission
Control Centre.
The technical snag was noticed during the
cryogenic fuel was being loaded.

•GSL
V Mk-III [Geosynchronous Satellite Launch V
ehicle
Mark- III] launch vehicle, which is the most powerful
launcher we have used till date.
•GSLVMk-III, chosen to launch Chandrayaan-2 spacecraft,
is a three-stage heavy lift launch vehicle developed by ISRO.
•The vehicle has two solid strap-on, a core liquid booster
and a cryogenic upper stage.

ehicle Diameter: 4.0m
Heat Shield (Payload Fairing) Diameter: 5.0m
Number of Stages: 3
Lift off Mass: 640 tonnes.
12. ROVER
Rover also known as Pragyan will have two instruments
on board.
On the surface of the Moon the instrument will test the
mineral and chemical compositions and also about soil and
rocks formation.
Data on and around the South Pole will be collected and
sent.
That is it will send information from the moon to Vikram
Lander.
13. ROVER
• Lander will send data to Orbiter.
•Then the Orbiter will send it to the ISRO centre.
This whole process will take about 15 minutes.
•So, it can be said that information sent from
Pragyan Robot will take about 15 minutes to
reach the ISRO centre in India.
•Dimensions: 0.9 × 0.75 × 0.85 m
•Power: 50 W
•Travel speed: 1 cm/sec.
14. ROVER
One of the instruments on Pragyan is a
Laser Induced Breakdown Spectroscope
(LIBS).
Coming from the Laboratory for
Electro Optic Systems (LEOS) in
Bengaluru, LIBS' main objective is to
identify the elements that are present near
the landing site.
To do this, laser pulses are fired at
various locations and the radiation from
the decayed plasma is analyzed.
17. LANDER
Lander also known as Vikram.
ISRO has named Lander after the founder of
ISRO and the father of Indian Space Program
Vikram Sarabhai.
The five-legged lander will have three
instruments onboard.
They are the RadioAnatomy of Moon-
Bound Hypersensitive Ionosphere and an
Atmosphere Probe (Rambha) that will
measure the density of the lunar sub surface
and changes around it.
18. LANDER
It’s named ‘Vikram’to honour the
late Dr Vikram Sarabhai, who was the
former chairman of ISRO and is
widely regarded as the ‘Father of the
Indian Space Programme’.
It has been developed to operate for
14 days or one Lunar day.
During this time period, the Vikram
Lander will be constantly
communicating with the Indian Deep
Space Network (IDSN) in Byalalu
near Bengaluru.
19. LANDER
The same network will be used by the Orbiter and Rover for
communications.
The lander weighs 1,471 kg including the Pragyan Rover (27 kg)
inside and it’s capable of generating about 650 W of electricity.
Further, the Chandra Surface Thermo physical Experiment will be
used to measure the thermal temperature around the South Pole of
the moon.
thirdly, is the instrument for Lunar SeismicActivity (ILSA)
which will measure the seismicity or quake or tremor-potential of
the region.
It will use scientifically for 15 days. Its initial design was made by
ISRO's SpaceApplication CentreAhmedabad.
Later, it was developed by the URSC (U R Rao Satellite Centre)
of Bengaluru.
ISRO has made an indigenous Lander on Russia's refusal.
20. LANDER
Dimensions: 2.54 × 2 × 1.2m
Gross lift-off mass: 1,471 kg (3,243 lb)
Propellant mass: 845 kg (1,863 lb)
Dry mass: 626 kg (1,380 lb)
Power generation capability: 650 W
23. ORBITER
Orbiter of Chandrayaan-2 will be installed
at 100 km above the moon and consists of
eight instruments.
Specifications of these instruments are not
provided that will be loaded on to the rocket.
But there will be an Imaging Infra-red
Spectometer (IIRS) which will try to identify
minerals and indicators of hydroxyl and
water molecules.
It will operate on solar power.
24. ORBITER
It will be circling the information
from Lander and Rover to the ISRO
Centre.
It will also bring the command sent
from ISRO to the lander and the
rover.
It was generated by Hindustan
Aeronautics Limited and handed it to
ISRO in 2015.
25. ORBITER
•Dimensions: 3.2 × 5.8 × 2.2 m
•Gross lift-off mass: 2,379 kg (5,245 lb)
•Propellant mass: 1,697 kg (3,741 lb)
•Dry mass: 682 kg (1,504 lb)
•Mission life: 1 year in lunar orbit
