With the occurrence of recent snowslips still fresh in mind, Indian Space Research Organization (ISRO) has fabricated the world’s lightest material called ‘Silica aerogel’, ‘blue air’ or ‘frozen smoke’ ,to keep the soldiers warm, the lightest ever made by mankind.

According to scientists at the Vikram Sarabhai Space Centre,a major space research centre of the ISRO, Thiruvananthapuram ,the material is useful in both outer space and Earth and has astounding thermal resistance.

Aerogels are among the lightest solid materials known to man, created by combining a polymer with a solvent to form a gel, and then removing the liquid from the gel and replacing it with air.

Key aspects of the ‘blue air’ :

  • This material can be used in soldier outfit to keep them warm during freezing temperatures
  • Aerogel has 99% air, it is being slated for use on ISRO’s next mission to the moon called Chandryaan-2
  • It has an excellent thermal resistance and if it is used as filler in soldiers’ uniforms it can save many lives at the Siachen Glacier

The material can be used in space and scientists are considering its usage in insulating rocket engines. It can soon replace winter outfits with light weight clothing for the Indian military.

The Defence Minister shall look into the education fund cap issue to resolve the problem
Minister of Defence Smt. Nirmala Sitharaman

New Delhi. Army chief General Bipin Rawat on Wednesday said Defence Minister Nirmala Sitharaman has promised to resolve the issue of a cap of Rs 10,000 on educational expenses paid to the children of defence forces martyrs.

The Army chief further revealed that the Chairman of the Chiefs of Staff Committee, Navy chief Admiral Sunil Lanba, has informed the Defence Minister of the issue, and she that has said the issue will be addressed on priority.

Defence Ministry sources reported that the Minister had held a meeting on the issue on Wednesday and a decision is likely to be announced soon.

General Rawat said: “For our martyrs, children are entitled (to) free education. It is a very good thing that the government has done. What has happened is possibly because of some misunderstanding– they have now capped it at Rs 10,000 because somebody must have calculated as to how much a person spends per month on child education,” .

“In our case, we have written to the government. I think the Defence Minister is completely seized of the problem. She is aware of it, and after we explained the reason to her… she said she is certainly concerned about it and will address the issue on priority,” he told reporters on the sidelines of an event here.

According to informed sources, Admiral Lanba, the most senior among the three service chiefs, wrote to the Minister to urge her to resolve the problem.

A letter dated September 13 by the Department of Ex-Servicemen Welfare had capped fee for tuitions and hostel expenses at Rs 10,000 per month.

The demand to a rollback on the decision was also raised by Punjab Chief Minister Amarinder Singh, and Union Minister of State for External Affairs General V.K. Singh, who is himself an Army ex-chief. (IANS)

Bengaluru, Oct 31: India will undertake another lunar expedition in early 2018 by sending a lander and a rover to explore the Moon to unravel its origin and present conditions, a top space official said on Monday.

The second Moon mission — Chandrayaan-2 — comes nearly a decade after India’s maiden lunar odessey in November 8, 2008, through a Polar Satellite Launch Vehicle (PSLV) rocket, which was launched on October 22 that year.

For launching Chandrayaan-1, the ISRO used PSLV rocket as the spacecraft carried only an impact probe vehicle to crash land on the Moon surface from its orbit.

“We are working towards putting an orbiter, lander, and the whole system in the lunar orbit in the first quarter of 2018,” state-run Indian Space Research Organisation (ISRO) Chairman A.S. Kiran Kumar told reporters here.

“The orbiter is getting ready and integrated,” he said.

“The lander and rover are undergoing tests. Some more tests are planned for December,” the ISRO chief said.

The lunar spacecraft will be launched onboard the space agency’s heavy rocket — Geosynchronous Satellite Launch Vehicle (GSLV) Mark II — from the second launch pad of the space port, located at Sriharikota in Andhra Pradesh.

As part of integration, the lander and rover would be configured for soft landing at a designated spot on the Moon and to conduct scientific experiments.

The rover will emerge from the lander to observe the lunar terrain and relay the data along with images through radio links.(IANS)

India to launch new Cartosat-2, 28 foreign satellites in December

India would launch its latest remote sensing satellite in Cartosat-2 series along with 28 foreign satellites riding piggy-back in December, a top space official said on Monday.

“In the next launch, we have a Cartosat along with 28 international commercial satellites, which we will launch in the second half of December,” said S. Rakesh, the Chairman and Managing Director of Antrix Corporation Ltd, the commercial arm of state-run Indian Space Research Organisation (ISRO).

There will be 25 nano satellites and three micro satellites from the US and other countries as co-passengers along the space firm’s own satellite of the Cartosat-2 series, he said.

The satellites will be launched into the orbit onboard the Polar Satellite Launch Vehicle (PSLV), Rakesh added.

The next launch will be keenly watched as it comes after ISRO’s PSLV rocket failed to deploy a spare navigation satellite on August 31. The rocket’s heat shield had failed to separate leaving the satellite inside the shield.

The Cartosat-2 is an earth observation satellite that is capable of providing high-quality images.

Imageries from Cartosat-2 series are used for cartographic, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, change detection to bring out geographical and man-made features and other Land Information System (LIS) and Geographical Information System (GIS) applications.

The previous satellite (Cartosat-2E) in the series was launched on February 15 this year from the spaceport at Sriharikota in Andhra Pradesh, about 90km northeast of Chennai.(IANS)
