chandrayaan 2 update: Indian spacecraft chandrayaan 2 will deploy a lander, orbiter, and rover to the moon. In July 2019, (chandrayaan 2 launch date), all three vehicles launched together into lunar orbit. The chandrayaan 2 lander name, Vikram carrying the rover made an unsuccessful attempt to settle in the southern hemisphere of the Moon. The orbiter keeps up its aerial observation of the Moon.
The Chandrayaan-1 orbiter, which launched in October 2008 and operated for 10 months, serves as the foundation for the project. Chandrayaan-2 has new technology and upgraded instrumentation designed for planetary missions in the future. While the chandrayaan 2 lander name, Vikram and rover, should they arrive successfully, were intended to last for one lunar day, the orbiter is expected to last for seven years.

Chandrayaan-2 mission objectives
Using upgraded instrumentation, the Chandrayaan-2 orbiter aims to expand on the data gathered during the Chandrayaan-1 mission. The Moon’s topography will be mapped, and the elemental abundances and surface mineralogy will be studied, along with the lunar exosphere and the search for hydroxyl and water ice signals.
The chandrayaan 2 lander name was given the name Vikram in honour of India’s first spaceflight pioneer, Vikram Sarabhai. At a latitude of roughly 70 degrees south, it would have touched down close to the Moon’s south pole.
Approximately 87 million USD was spent on the mission.
The project expands on the Chandrayaan-1 orbiter, launched by ISRO in October 2008 and used for ten months. For next planetary missions, chandrayaan 2 information has upgraded instruments and new technology. While the lander and rover were anticipated to endure one lunar daytime session had they successfully landed, the orbiter is scheduled to run for seven years.
Context: chandrayaan 2 update
In the past two years, the Chandrayaan-2 mission’s Orbiter and other sensors have gathered a plethora of fresh chandrayaan 2 information and chandrayaan 2 images that has increased our understanding of the Moon and its surroundings.
How did Chandrayaan-2 end up?
India’s second lunar mission, (chandrayaan 2 launch date ) which was 22 July 2019, but unfortunately chandrayaan 2 landing, had failed to soft-land on the moon’s surface.
In the last seconds, the lander, and rover developed a problem, crashed, and were completely destroyed.
What, therefore, makes this mission still crucial?
The orbiter and other project elements have continued to collect chandrayaan 2 information and chandrayaan 2 images routinely despite the loss. The data gathered thus far by the scientific payloads has been made accessible by the Indian Space Research Organisation (ISRO), some of which required evaluation and analysis.
What kind of data is being gathered by chandrayaan 2 landing?
The mission has provided the most accurate information to date regarding the existence of water molecules on the moon.
Minor element presence: Remote sensing has allowed for the first time detection of sodium, manganese, and chromium. The discovery may open up new avenues for research into planetary differentiation, nebular circumstances, and lunar magmatic evolution.
Information about solar flares: Numerous microflares have been detected for the first time outside the active zone, and, in the words of ISRO, this “has tremendous ramifications on the understanding of the mechanism behind heating of the solar corona,” a long-standing unanswered question.
Exploration of the areas that are always in shadow, as well as the craters and boulders that are hidden beneath the regolith, the loose deposit that makes up the top surface and extends down to a depth of 3 to 4 metres. This should enable scientists to pinpoint potential locations for drilling and future landing operations, including those involving people.
chandrayaan 2 upsc is one of the important topics which is added to UPSC syllabus.
What instruments does the Chandrayaan-2 orbiter have?
Terrain Mapping Camera 2 (TMC 2): A scaled-down version of the Terrain Mapping Camera used onboard the Chandrayaan 1 mission, TMC 2 is used to build a 3D map or chandrayaan 2 images of the lunar surface. Its main goal is to study the lunar surface in the panchromatic spectral region (0.5-0.8 microns) from orbit with a high spatial resolution of 5 metres.
Chandrayaan 2 Large Area Soft X-ray Spectrometer (CLASS): CLASS analyses the X-ray Fluorescence (XRF) spectra of the Moon to look for the presence of elements that make rocks, such as sodium, calcium, titanium, iron, and magnesium. By detecting the distinctive X-rays that these substances emit when energised by the Sun’s beams, the XRF technique can identify these substances.
Solar X-ray Monitor (XSM): Supports CLASS by tracking the Sun’s and its corona’s X-ray emissions and determining the amount of solar radiation included in those rays. measures the entire solar X-ray spectrum in the 1–15 keV energy range every second.
Orbiter High Resolution Camera (OHRC): Generates DEMs (Digital Elevation Models) that will be utilised to look for potential dangers by taking pictures of the landing site from two look angles. They will be used for additional scientific research after landing. Images from the OHRC have a resolution of 0.25 metres and cover a 12-by-3-kilometer area.
Synthetic Aperture Radar (SAR) is an L- and S-band radar device that can measure the thickness and electrical conductivity of lunar regolith as well as detect water ice inside craters that are perpetually in shadow. The L-band radar mapper that will orbit the Moon for the first time is this one.
The Imaging Infrared Spectrometer (IIRS) analyses and maps the distribution of molecular water and hydroxyl (OH) in the polar regions of the moon. able to detect light with a wavelength of 0.8 to 5 microns.
A neutral mass spectrometer called Chandra Atmospheric Composition Explorer 2 (ChACE-2) will collect samples of atoms from the thin atmosphere above the Moon’s poles. The CHACE experiment from Chandrayaan 2 is expanded upon in CHACE 2.
The Dual Frequency Radio Science (DFRS) experiment uses X-band (8496 MHz) and S-band (2240 MHz) transmissions that are broadcast to Earth-based receivers to examine the temporal development of electron density in the lunar ionosphere.One of ISRO’s most significant projects is the Chandrayaan Mission, and students are now learning about it as part of the Chandrayaan 2 Upsc curriculum..
