As everyone is aware, the
ISRO Chandrayaan-3 will be launched by the Launch Vehicle Mark III (LVM3), also
known as the Geosynchronous Satellite Launch Vehicle Mark III, at 2:35 PM IST on
Friday, July 14. The third lunar mission for India. The Isro changed a few key
things in Chandrayaan-3 to enable the landing of a rover on the lunar surface.
In this article, we'll examine several key features of Chandrayaan-3 and how it
differs from Chandrayaan 2.
The main objectives of
Chandrayaan-2 were to do a soft landing on the lunar surface and to send out a
rover to study the area around the Moon's South Pole. The lander, Vikram, was
unable to land successfully, hence the mission was only partially successful. Similar to Chandrayaan-2, Chandrayaan-3 is
anticipated to land on the Moon and send out a rover with the aim of completing
the tasks left unfinished by Chandrayaan-2.
Designing a new lander
for Chandrayaan-3 was part of ISRO's effort to overcome the problems
encountered during the Chandrayaan-2 landing attempt. The lander is anticipated
to feature modifications to increase the likelihood of a successful landing as
well as lessons learned from the prior mission.
The main components of Chandrayaan-2 were an orbiter, a lander, and a
rover. As the orbiter from Chandrayaan-2, known as the "Chandrayaan-2
Orbiter," is still operational and performing well, ISRO declared that it
would leave the orbiter component out of Chandrayaan-3. Chandrayaan-3 will
largely concentrate on the lander and rover components by omitting the orbiter
redundancy.
The lander and rover have
a 14-day (one lunar day) mission life.
The payload has been placed in the RAMBHA-LP to assess the density of
the near-surface plasma (ions and electrons) and how it varies over time, using
the Langmuir probe. (Chandra's Surface Thermophysical Experiment): To conduct
measurements of the thermal characteristics of the lunar surface close to the
poles with the help of the ChaSTE.
Measure seismic activity at the landing site and map the relationship
between the lunar crust and mantle using the ILSA (Instrument for Lunar Seismic
Activity).
To further our
understanding of the lunar surface, the rover's payload includes the APXS
(Alpha Particle X-Ray Spectrometer) and LIBS (Laser-Induced Breakdown
Spectroscope) instruments. The APXS (Alpha Particle X-Ray Spectrometer)
measures the elemental composition (Mg, Al, Si, K, Ca, Ti, and Fe) of lunar
soil and rocks near the lunar landing site.
Chandrayaan-3 further The
Indian Space Research Organization (ISRO) is working on a payload called
Spectro-polarimetry of Habitable Planet Earth (SHAPE). It is made to measure
the polarization of light using spectro-polarimetry, which can be used to
analyze the Earth's atmosphere.
For Chandrayaan-3, ISRO
worked in conjunction with other nations and space organizations to increase
the likelihood of success. The objective is to increase the mission's overall
capabilities by utilizing the knowledge and assets of international partners.
Isro has generally been
in the forefront of India's advances in science and technology throughout the
past few years. Chandrayaan-1 and 2, Mars Orbiter Mission (MOM), GSLV Mk III,
IRNSS (NavIC), GSAT Communication Satellites, Cartosat Satellites, and Reusable
Launch Vehicle Technology Demonstrator (RLV-TD) are only a few of the missions
launched by Isro. Isro is one of the world's leading organizations for space
research as a result of these activities. I sincerely hope that the
Chandrayaan-3 mission is a success and that the scientists' labor of love pays
off.
