NEW DELHI: The training of four astronauts in Russia for India’s first human space flight will complete this month and the second phase of training, which will be module specific, is scheduled to take place in the country, Union minister Jitendra Singh said on Thursday.
India’s first human space flight, ‘Gaganyaan‘, will be preceded by an unmanned flight by 2021, followed by another flight carrying “Vyom Mitra”.
“Four astronauts are being trained for India’s first human space flight. Their one-year training in Russia is completing this month, with some delay on account of the COVID pandemic,” Singh told PTI.
“The second phase of training, which will be module specific, is scheduled to take place in India,” the minister said.
The ‘Gaganyan’ flight, estimated to be around Rs 9,023 crore, is scheduled sometime before or on the eve of the 75th anniversary of India’s independence.
India’s heaviest launch vehicle, ‘Bahubali’ GSLV Mark-III, will the carry astronauts to space.

Not in ‘public interest’ to disclose quantity of uranium extracted in country: Government | India News – Times of India

NEW DELHI: There are a total of eight uranium mines in the country, but it is not in the “public interest” to disclose the quantity of uranium extracted from these mines, the Rajya Sabha was informed on Thursday.
In a written reply to a question in the Rajya Sabha, Union Minister Jitendra Singh said there are eight uranium mines in the country — seven in Jharkhand and one in Andhra Pradesh.
“It is not in the public interest to disclose the quantity of uranium extracted from these mines,” he said.
Uranium is processed through Uranium Corporation of India Ltd (UCIL), a public sector undertaking under the Department of Atomic Energy (DAE).
Singh, the minister of state in the Prime Minister’s Office, said the grade of the ore mined from various deposits is very poor in India compared to that of other countries.
The ore bodies are narrow and not suitable for extraction by mass mining methods, he said.
These deposits are also not suitable for extraction by low cost in-situ leaching technology which is a common method of extraction of uranium concentrate in many of the major uranium producing countries.
On the cost of processing of the ore, he said, “India also adopts alkali leaching technology for extraction of uranium from very low grade ore occurring in dolostone host rock in Tummalapalle region in Andhra Pradesh, which cannot be extracted by acid leaching technology.”
“This is a costlier process developed indigenously and has been adopted successfully. In view of these constraints, the extraction and processing cost of uranium in India is higher compared to that of other countries,” Singh said.
In response to another question, he said India has entered into an agreement with Russia for supply of fuel for Russian Reactors at Kudankulam Nuclear Power Project (KKNPP) throughout the operation period of power units.
Uranium purchase agreement has also been entered with Canada, Kazakhstan, Russia and Uzbekistan.
He added that Inter Governmental Agreement (IGA) for cooperation in peaceful uses of nuclear energy have been signed with 17 countries like Argentina, Australia, Bangladesh, Canada, Czech Republic, the European Union, France, Japan, Kazakhstan, Mongolia, Namibia, the Republic of Korea, Russia, Sri Lanka, the UK, the US and Vietnam.

Parliament proceedings | Envisaged for a year, Chandrayaan-2 orbiter likely to last for 7 years

The mission has accomplished the objective of expanding lunar scientific knowledge

The life of the orbiter of Chandrayaan-2 was initially envisaged for a year but the Indian Space Research Organisation (ISRO) expects it to last for seven years, Union Minister Jitendra Singh said on Wednesday.

In a written response to a question in the Lok Sabha on India’s second lunar mission, Jitendra Singh, the Minister of state in the Prime Minister’s Office, said Chandrayaan-2 was a highly complex mission to develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.

The mission comprised an orbiter, lander and rover.

Planned to land on the South Pole of the Moon, Chandrayaan-2 was launched on July 22, 2019. However, the lander Vikram hard-landed on September 7, 2019, crashing India’s dream to become the first nation to successfully land on the lunar surface in its maiden attempt.

“But for achieving soft landing at the intended spot, the other objectives of the mission have been significantly attained. So much so, that against an initially envisaged one-year life of orbiter, we expect it to be serving for seven years,” Mr. Singh said.

The mission has accomplished the objective of expanding lunar scientific knowledge through detailed study of topography, mineralogy, surface chemical composition, thermo-physical characteristics and tenuous lunar atmosphere leading to a better understanding of the origin and evolution of the moon, it added.

In August last year, Mr. Singh had announced that Chandrayaan-2 orbiter has captured the images of craters on the Moon. They were christened “Sarabhai crater” after Vikram Sarabhai, father of the Indian space programme.

The Sarabhai Crater captured in 3D images shows that it has a depth of around 1.7 kilometres, taken from its raised rim, and the slope of crater walls is in between 25 to 35 degree. These findings will help space scientists to understand further the process on the lunar region filled with lava, Singh had said.

ISRO’s missions are known to have an enhanced life than what is earlier envisaged.

The planned life span of Mars Orbiter Mission (MOM)/ Mangalyaan after its insertion into the Mars orbit on September 24, 2014 was six months and it was to complete on March 24, 2015. However, the MOM is still functioning and sending pictures.
