3rd Lunar mission in 15 years! Moon truly beckons ISRO
Bengaluru (PTI): Three Lunar missions in 15 years! It seems the Moon truly beckons ISRO. And why not? Scientists found frozen water deposits in the darkest and coldest parts of the Moon's polar regions for the first time using data from the Chandrayaan-1 spacecraft in 2009.
Chandrayaan-1, India's first mission to the Moon, was launched on October 22, 2008 from Sriharikota spaceport in Andhra Pradesh.
The spacecraft, carrying 11 scientific instruments built in India, the USA, the UK, Germany, Sweden and Bulgaria, orbited around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon.
After the successful completion of all the major mission objectives, the orbit was raised to 200 km in May 2009. The satellite made more than 3,400 orbits around the Moon.
The orbiter mission, which had a mission life of two years, was, however, prematurely aborted after communication with the spacecraft was lost on August 29, 2009.
"Chandrayaan-1 achieved 95 per cent of its objectives," said the then ISRO Chairman G Madhavan Nair.
And a decade later, Chandrayaan-2, comprising an orbiter, lander and rover, was successfully launched on July 22, 2019.
The objectives of the country's second mission to the Moon were scientific studies by payloads onboard the orbiter, and technology demonstration of soft landing and roving on the lunar surface.
Most of the components of technology demonstration, including the launch, orbital critical manoeuvres, lander separation, de-boost and rough braking phase were successfully accomplished.
However, the lander with a rover in its belly crash-landed on the lunar surface in the final lap, failing in its objective to touch down gently.
"We narrowly missed it (soft landing on the Moon in Chandrayaan-2 mission) in the last two km (above the lunar surface)," Nair had told PTI on Monday.
However, all the eight scientific instruments of the orbiter, which had separated from the lander and rover, are performing as per design and providing valuable scientific data.
Due to the precise launch and orbital manoeuvres, the mission life of the orbiter increased to seven years, according to ISRO.
In fact, ISRO on Monday said that two-way communication between the Chandrayaan-2 orbiter and the Chandrayaan-3 lunar module has been established.
Moreover, the discovery of water on the Moon in 2009 was a hugely significant event, following which scientists, using data from an instrument which flew aboard India's Chandrayaan-1 spacecraft, created the first map of water trapped in the uppermost layer of the Moon's soil. It would prove useful to future lunar explorers, ISRO officials said.
The study, published in the journal Science Advances, builds on the initial discovery in 2009 of water and a related ion hydroxyl, which consists of one atom each of hydrogen and oxygen in lunar soil.
Scientists from Brown University in the US used a new calibration of data taken from NASA's Moon Mineralogy Mapper, which flew aboard the Chandrayaan-1 spacecraft in 2008, to quantify how much water is present on a global scale.
Using data collected by India's Chandrayaan-1 mission, NASA has detected magmatic water locked under the surface of the Moon.
The findings represent the first remote detection of this form of water that originates from deep within the Moon's interior, NASA researchers had said.

MP HC sets up judicial commission to probe water contamination in Indore
Indore (PTI): The Indore bench of Madhya Pradesh High Court on Tuesday set up a commission of inquiry comprising a former HC judge to probe the issue of water contamination in city's Bhagirathpura, saying the matter requires probe by an independent, credible authority and "urgent judicial scrutiny".
It also directed the commission to submit an interim report after four weeks from the date of commencement of proceedings.
A division bench of Justices Vijay Kumar Shukla and Alok Awasthi constituted the commission while hearing several public interest litigations (PILs) filed simultaneously regarding the deaths of several people in Bhagirathpura due to the consumption of contaminated water.
The HC reserved the order after hearing all the parties during the day, and released it late at night.
The state government on Tuesday told the HC that the deaths of 16 people in Indore's Bhagirathpura area was possibly linked to a month-long outbreak of vomiting and diarrhoea caused by contaminated drinking water.
The government presented an audit report of 23 deaths from the current gastroenteritis epidemic in Bhagirathpura before the bench, suggesting that 16 of these fatalities may have been linked to the outbreak of vomiting and diarrhoea caused by contaminated drinking water.
The report, prepared by a committee of five experts from the city's Government Mahatma Gandhi Memorial Medical College, stated that the deaths of four people in Bhagirathpura were unrelated to the outbreak, while no conclusion could be reached regarding the cause of death of three other people in the area.
During the hearing, the high court sought to know from the state government the scientific basis behind its report.
The division bench also expressed surprise at the state government's use of the term "verbal autopsy" in relation to the report, sarcastically stating that it had heard the term for the first time.
The HC expressed concern over the Bhagirathpura case, stating that the situation was "alarming," and noted that cases of people falling ill due to contaminated drinking water have also been reported in Mhow, near Indore.
In its order, the HC said the serious issue concerning contamination of the drinking water supply in Bhagirathpura area allegedly resulted in widespread health hazards to residents, including children and elderly persons.
According to the petitioners and media reports, death toll is about 30 till today, but the report depicts only 16 without any basis or record, it said.
It is averred that sewage mixing, leakage in the pipeline, and failure of civic authorities to maintain potable water standards have led to the outbreak of water-borne diseases. Photographs, medical reports, and complaints submitted to the authorities prima facie indicate a matter requiring urgent judicial scrutiny, the HC said.
"Considering the gravity of the allegation and affecting the right to life under Article 21 of the Constitution of India and the need for an independent fact-finding exercise, the Court is of the opinion that the matter requires investigation by an independent, credible authority," it said.
"Accordingly, we appoint Justice Sushil Kumar Gupta, former judge of the Madhya Pradesh High Court, a one-man commission of inquiry into the issues relating to water contamination in Bhagirathpura, Indore, and its impact on other areas of the city," the HC added.
As per the order, the commission shall inquire into and submit a report on the cause of contamination -- whether the drinking water supplied to Bhagirathpura was contaminated; and the source and nature of contamination (sewage ingress, industrial discharge, pipeline damage etc).
The panel will also probe the number of actual deaths of affected residents on account of contaminated water; find out the nature of disease reported and adequacy of medical response and preventive measures; suggest immediate steps required to ensure safe drinking water as well as long-term infrastructural and monitoring reforms.
It will also identify and fix responsibility upon the officers and officials found prima facie responsible for the Bhagirathpura water contamination incident, and suggest guidelines for compensation to affected residents, particularly vulnerable sections.
The commission shall have powers of a civil court for the purpose of summoning officials and witnesses; calling up records from the government department, hospitals, laboratories and civic bodies; ordering water quality testing through accredited laboratories; conducting spot inspections.
All state authorities involving district administration, Indore Municipal Corporation, public health engineering department and Madhya Pradesh Pollution Control Board shall extend full co-operation and provide records as sought by the commission, it said.
The state government shall provide office space, staff, and logistical support to the commission, it said.
During the hearing in the day, the state government also presented a status report to the court in this matter.
According to reports, a total of 454 patients were admitted to local hospitals during the vomiting and diarrhea outbreak, of whom 441 have been discharged after treatment, and 11 are currently hospitalised.
According to officials, due to a leak in the municipal drinking water pipeline in Bhagirathpura, sewage from a toilet was also mixed in the water.
