What is New about Chandrayaan 3 ISRO 2020 projects
![]() |
Project Chandrayaan |
ISRO Indian
Space Research Organisation has been estimated cost for Chandrayaan-3, is above
600 crores, This will be the third Moon mission for India, After the failure to
land a probe on Moon in the first attempt on Sept. 2019 i.e. Chandrayaan-2.
ISRO
decided to launch Chandrayaan-3 in 2020, Indian govt Approved the project and
they have already started the project, The lander Rover and propulsion module
will cost Rs. 250 crore, while the launch service will cost another Rs. 365
crore.
Chandrayaan-3 the target set for the crucial launch is November 2020, ISRO is looking for more
than 25 missions this year and they are confident each project work will happen
simultaneously, For 2020 projects, land acquisition for the second spaceport
in Kulasekarapattinam in Tuticorin, which is in Tamil Nadu. ISRO needs 2300
acres land for this second spaceport, ISRO has requested for Rs.120 crore for
new launchpad for SSLV Small Satellite Launch Vehicle which will be part of
this proposed spaceport.
Chandrayaan-3’s configuration will be similar to that of its predecessor, Chandrayaan-2,
Chandrayaan-3 will also have a lander and Rover with a propulsion module. For
Chandrayaan-3 ISRO is planning for landing at the same location as the
Chandrayaan-2, the lander of which crash-landed on the Moon surface just
moments before it was supposed to soft-land.
Chandrayaan-3
mission, as the second attempt has been dubbed, Engineers and Scientists at
ISRO will design and build an entirely new lander and Rover. Since the
Chandrayaan-2 mission already has a functional orbiter that is currently in
orbit around the Moon, Chandrayaan-3 will not feature an orbiter of its own. In
its stead, the Lander and Rover will be accompanied by an additional,
detachable module that packs the engine & fuel needed for the journey.
This module
will tentatively be called the “Propulsion Module”, The Chandrayaan-3 mission
will also feature fewer orbital maneuvers than Chandrayaan-2, which had a total
of 6 orbit raisers around the Earth and Moon.
ISRO is
looking to improve the data transfer capability on the lander for the new
mission, which will help transfer lunar surface images from the lander imager
camera right from the beginning of the powered descent, likely to be from about
30 km from the lunar surface.
ISRO has the noted Data rate, telemetry, and orientation to be appropriately arrived at based
on the descent trajectory. Chandrayaan-3 is expected to have solar cells on
four sides of the lander, its predecessor had it only on three sides to improve
performance. Feasibility of populating solar cells on the fourth side vertical
panel where Rover is accommodated to be studied to avoid power issues if
landing happens with large attitude error resulting in absence of Sun in the
plane.
The panel
which will meet again later this year, has also tasked, to look at establishing
margins for different touchdown conditions. Strengthening of lander legs to be
considered in Chandrayaan-3, power, and communication between lander and ground
to be ensured post landing irrespective of lander orientation.
The
Chandrayaan-3 is the successor to the Chandrayaan-2 mission and it will likely
attempt another soft-landing on the lunar surface.
