It’s time to reassess India’s space feat




This year marks an important milestone for the Indian Space Research Organisation (ISRO) as it observes the 40th anniversary of two of its pioneering projects. Two missions executed successfully in 1975 were the launch of India’s first satellite, Aryabhatta, onboard a Soviet launcher and an experiment in education television called SITE (Satellite Instructional Television Experiment) using an American satellite.
Both projects were conducted much before India had developed its own launching capability, and were actually designed to test use of space technology for wider societal applications. SITE was an experiment in deploying space technology for tele-education, while Aryabhatta tested feasibility of tele-medicine though its primary objective was to gather scientific data.
The seeds of SITE were sown in the 1960s by Vikram Sarabhai, father of the space programme, who believed that application of space technology could make a difference to development and economic growth. Four decades later, has Sarabhai’s vision translated into reality?

Technology-wise, the space agency has made tremendous advancements. India is capable of designing, fabricating and launching a range of satellites and offers launch services to other countries as well. Over the past two decades, ISRO has launched satellites for several applications — communication, broadcasting, weather forecasting, disaster management, remote sensing, cartography, search and rescue, distant education and strategic use. Soon there will be a cluster of navigation satellites as well.
All this, along with scientific missions to the moon and Mars, augurs well for the emergence of ISRO as a robust space agency and positioning of India as a leading space faring nation.
However, one has to critically examine the real impact of space technology on the ground. The gains are clearly visible in areas like broadcasting, weather prediction and communications, but the experience in areas like telemedicine, distant education and remote sensing has rather been mixed. Going by the number of remote sensing satellites India has launched and expertise it has developed, ISRO should be doing roaring business in remote sensing imagery.
But, as performance audits in recent years have revealed, utilisation of remote sensing data has been below par. Some satellites were planned without adequate assessment of data needs, resulting in idling of their capacity. Data sharing policy is also cumbersome. As regards use of data for government projects, lack of coordination caused poor usage. Audits revealed similar results with ISRO’s distant education satellite, Edusat. Ground infrastructure for utilising signals beamed from the satellite was not ready in many states several months after the satellite was up in the sky nor was content generation up to the mark.
All these issues, most of which are managerial rather than technological, need to be fixed before ISRO is burdened with more application projects as is being done currently. At the suggestion of the prime minister, some 60 ministries and government agencies have proposed 170 projects for using space technology under nine themes like agriculture, energy, water management, etc.
Instead of spreading available resources sub-optimally across multiple projects, it will be wiser to focus on key applications like education and tele-medicine by correcting past mistakes and by having a clear structure for managing large application projects.

Isro may give N-boost to Chandrayaan-2

MUMBAI: Isro is mulling use of nuclear technology to increase the life span of its second moon mission Chandrayaan-2, which is slated for lift-off in 2017.

Significantly, the technology, which will use a very small amount of nuclear energy, will have no fission. Simply put, this system will ensure complete safety. It is believed Chandrayaan-2 will have a life span of one year.

The spacecraft will be carried by the indigenously developed 3-stage Geosynchronous Satellite Launch Vehicle (GSLV Mark 2), which — riding on a string of recent successes — has transformed from being Isro's "naughty boy" to the agency's "most adored boy".

BARC director Sekhar Basu told TOI that his organization has already initiated studies regarding the use of nuclear technology in this mission.

"We have to start from the scratch as the required nuclear material is not available and nobody will give it to us. We have to develop them on our own in our reactorsand produce them artificially," he said.

Basu, while acknowledging that the process could take time, said some aspects of the mission are still being worked out. The use of nuclear technology for this mission assumes significance as Chandrayaan-1's life span was cut short by nearly two months due to a technical problem. It was launched on October 22, 2008, with a 1-year mission life. However, it stopped communicating on August 29, 2009.

The mission profile for Chandrayaan-2 includes an orbiter, lander and a rover, which will study the mineralogy of the lunar surface.

On August 7, 2009, former Isro chief Madhavan Nair had told the media at IIT-B: "We are thinking of powering some parts of Chandrayaan-2 with nuclear power." However, in the past six years this plan had remained on paper following widespread apprehensions about use of nuclear technology in space missions. The plan has now been revived.

According to nuclear experts, the advantage of a nuclear power system in a spacecraft is that it functions independently of sunlight, which is necessary for deep space exploration.

ISRO Will Launch One Satellite Every Month Soon: Mylswamy

The ISRO would launch at least one satellite every month in the forthcoming days, said Mylswamy Annadurai, the man behind the moon mission ‘Chandrayaan-1’, and current Director of ISRO Satellite Centre (ISAC), on Friday.
Speaking at a conference on ‘Remote Sensor and Satellite Communication’ sponsored by ISRO, Mylswamy said that Chandrayaan-1 is the 69th satellite launched towards the moon, and the first by India following the USA, Russia, Japan, China and the European Union. He added that Chandrayaan-1 is the first satellite to confirm the presence of traces of water in the moon.
Mylswamy said, “Currently, 10 Indian satellites are revolving around the earth in an effort to search for mineral resources underneath the surface of the earth. The United States needed five attempts and Russia (including the erstwhile USSR) needed nine attempts to reach Mars. China and Japan are yet to succeed in their mission to reach Mars, but India succeeded at the very first attempt itself, that too with indigenous and less expensive technology.”
“The reason for Mission on Mars (MoM) being less expensive is because the satellite was launched in such a way that it used very less fuel during its travel time of nine months, and was made to move along the force of gravity of the earth, as choosing a linear path may consume more fuel,” he added.
“The only thing scientists need to do is to increase the speed of the satellite at the right time in the right direction, using Remote Sensing and Satellite Communication technologies,” he stressed.
He shared his experience of how he started his career in ISRO in 1982 with a satellite at an altitude of 400 km from the earth’s surface, and now having reached the moon at a distance of nearly four lakh kilometres.
Mylswamy, in his speech, told that life will become a poem, if we do things with passion and interest. He pointed out that it is the right time for India to grow, as majority of the population comprises of youth.
During an interactive session, he mentioned that there is no need for an inferiority feeling for women in the field of space research and technology, as long as they prove their talent. He proudly mentioned that scientist Valarmathi, who has been awarded Abdul Kalam award by the Government of Tamil Nadu, was his junior.
Fondly recalling his memories with Abdul Kalam, Mylswamy said that when everybody used to appreciate his achievements, Kalam used to ask him “What next?”, which encouraged him to do more. Mylswamy is also Project Director of Chandrayaan-2, which is set to be launched by the end of 2017 or by early 2018.

ASTROSAT set for Sep 28 launch

ASTROSAT, satellite for the first dedicated Indian astronomy mission aimed at studying celestial objects, is scheduled for launch on September 28, a senior Indian Space Research Organisation official today said.

"The satellite is scheduled for launch on board the launch vehicle PSLV C-30, on September 28 morning 10 am," Director, Public Relations, ISRO, Deviprasad Karnik told PTI.

He said "now the vehicle assembly is almost completed; along with ASTROSAT there will be six co-passengers -- one satellite each from Indonesia and Canada, and four nano satellites from the US. These satellites have already arrived and those preparations are going on."

These six satellites are meant for maritime surveillance.
ISRO Satellite Centre (ISAC) had transported ASTROSAT to the Satish Dhawan Space Centre at Sriharikota, using a specially-designed Satellite Transportation System (STS) on August 16.

The mission is capable of performing observations in ultra-violet (UV), optical, low and high-energy X-ray wavebands at the same time, ISRO had earlier said.

It had said ASTROSAT is the first mission to be operated as a space observatory by ISRO.
ASTROSAT carries four X-ray payloads, one UV telescope and a charge particle monitor.
Apart from ISRO, four other Indian institutions -- Tata Institute of Fundamental Research, Indian Institute of Astrophysics, Inter-University Centre for Astronomy and Astrophysics and Raman Research Institute -- are involved in payload development.

Two of the payloads are in collaboration with Canadian Space Agency and University of Leiscester, UK, ISRO had said.

ISRO ready for one satellite launch every month: ISAC chief


The ISRO is bracing up for one satellite launch every month in the days ahead and has 22 satellite launches lined up for the near future, said M. Annadurai, Director, ISRO Satellite Centre (ISAC).
Speaking to The Hindu on the sidelines of an interaction programme with students of Vidyavardhaka College of Engineering organised by the CII Mysuru chapter here on Saturday, Mr. Annadurai said space assets had limited life and their requirement from ATMs to telemedicine and every conceivable aspect of present day living had made it imperative to keep them functional.
“While 22 satellites have been lined up and are in the pipeline for a launch at the rate of one satellite per month, the actual requirement for the country is reckoned to be around 52 satellites in the next 3 or 4 years,” he said.
On the immediate missions, Mr. Annadurai said ASTROSAT is slated for launch later this month and described it as a multi-wave length observatory capable of studying distant celestial objects and the first dedicated astronomy satellite to be launched by the ISRO.
Underlining the imperatives of harnessing space technology to shore up the quality of life, Mr. Annadurai said using information and communication technology gave the concept of e-governance but harnessing space assets for effective day-to-day governance can usher in the concept of Space Governance.
Earlier, Mr. Annadurai delivered a lecture on science as a way of life which was dedicated to the former President and scientist the late A.P.J. Abdul Kalam.
Interacting with the students, he said ISRO was also contemplating a solar mission to study the Sun and Mission Aditya entailed studying the corona and the solar flares from a low earth orbit.

ISRO, airports authority to hold satellite navigation meet


With India entering the satellite-based navigation with its two projects GAGANand IRNSS, the Indian space agency and airports authority are jointly organising an user meet for these services, the space agency said on Wednesday.
In a statement, the Indian Space Research Organisation (ISRO) said it agency along with Airports Authority of India (AAI) would be hosting a Global Navigation Satellite System – User Meet 2015 on October 8 at the ISRO Satellite Centre in Bengaluru.
The theme of the meet is `Towards Self Reliance in Satellite Navigation’.
According to ISRO, India has entered the realm of satellite-based navigation with its two pioneering projects GPS Aided Geo Augmented Navigation System (GAGAN) and Indian Regional Navigation Satellite System (IRNSS).
The GAGAN is for precision approach for aircrafts while IRNSS provides independent positioning with the help of four satellites.
The proposed meet intends to bring together the navigation satellite-based industries, receiver manufacturers, positioning, navigation and timing service providers, application developers, content providers and the user community along with the academia on a common platform.
The meet also aims to explore various avenues to utilise the Indian satellite-based navigation services for the socio-economic benefits of the country.
The Indian space agency said the one-day event would hold a plenary session with talks delivered by eminent personalities from the global navigation satellite system community, technical sessions and a panel discussion apart from an exhibition showcasing various products.

Mangalyaan Turns One, ISRO Celebrates Birthday





India’s globally acclaimed Mars mission completed one year today with Indian Space Research Organisation releasing the Mars Atlas to mark the feat of the Orbiter whose life is now expected to last many more years.
It contains a compilation of images acquired by Mars Colour Camera (MCC) and results obtained by other payload in a form of scientific atlas.
ISRO will also be bringing out a book, ‘Fishing hamlet to Mars’ on November 5 to mark the anniversary of Mars Orbiter Mission (MOM), whose success has boosted India’s global standing as a space power.
It was on this day last year that India scripted space history when it successfully placed its low-cost Mars spacecraft in orbit around the Red Planet on its very first attempt, breaking into an elite club of three nations.
The space probe entered the Mars orbit on September 24, almost a year after its launch, and made its home around the Red Planet.
European Space Agency (ESA) of European consortium, National Aeronautics and Space Administration (NASA) of the US and Roscosmos of Russia are the only three other agencies which had so far sent their missions to Mars.
Only 21 of the total of 51 missions sent to Mars by various countries have been successful before MOM.
The Mars mission of the ISRO is aimed at establishing the country’s capability to reach the red planet and focus on looking for the presence of methane, an indicator of life in Mars.
The make-or-break tricky manoeuvre was carried out on this very date last year, with clockwork precision on the refrigerator sized spacecraft as planned in the presence of Prime Minister Narendra Modi, who exultantly described it as “a historic occasion”, saying the country has achieved the “near impossible”.
The life of the Mars Orbiter Spacecraft which now ISRO says can last “many years” was earlier intended for only six months, and later extended for another six months in March this year.

India Set to Cross Half Century Mark in Launching Foreign Satellites




In an indication of its prowess in launching satellites for a fee, India will in all likelihood cross the half century milestone next week as six foreign satellites are scheduled for launch on September 28 at one go, the Indian space agency said on Thursday.
The Indian Space Research Organisation (ISRO) said the rocket polar satellite launch vehicle (PSLV) will launch the country’s own ASTROSAT weighing 1,513 kg at 10 a.m. on Monday, apart from four from the US and one each from Indonesia and Canada.
The PSLV will carry a total payload of 1,631 kg during this mission.
The ISRO said standing 44.4 metres tall and weighing 320.2 tonnes, the PSLV rocket will blast off from the first launch pad with seven satellites.
Just over 22 minutes into the flight, the rocket will eject ASTROSAT at an altitude of around 650 km above the earth.
Soon after, six other satellites will be put into orbit and the whole mission will come to an end in just over 25 minutes.
ASTROSAT, with a life span of five years, is India’s first dedicated multi-wavelength space observatory that will help in understanding our universe.
The space agency said ASTROSAT will observe the universe through optical, ultraviolet, low and high energy X-ray components of the electromagnetic spectrum, whereas most other scientific satellites are capable of observing through a narrow wavelength band.
The Indonesian 76 kg LAPAN-A2 is a micro-satellite from the National Institute of Aeronautics and Space, meant for providing maritime surveillance using automatic identification system (AIS), supporting Indonesian radio amateur communities for disaster mitigation and carrying out earth surveillance using video and digital camera.
The 14-kg NLS-14 (Ev9) of Space Flight Laboratory, University of Toronto Institute for Advanced Studies, is also a maritime monitoring Canadian nano satellite using the next generation AIS.
The remaining four LEMUR nano satellites from Spire Global Inc., San Francisco, US, are non-visual remote sensing satellites, focusing primarily on global maritime intelligence through vessel tracking via AIS and high fidelity weather forecasting using GPS radio occultation technology, the ISRO said.
Till date, India has launched 45 foreign satellites for a fee.

Centre to engage Isro satellites to check illegal mining activity


Concerned about rampant illegal mining in several mineral-rich states of the country, the ministry of mines is planning to make use of indigenous space technology to protect mineral resources, a top ministry official said.
“We are talking to the Indian Space Research Organisation (Isro) about using remote sensing satellites and GPS technology to check illegal mining,” mines secretary Balwinder Kumar said.
PM Narendra Modi on September 7 directed various ministries to make use of space-based technology in collaboration with Isro for the benefit of the common man. “We have asked the Indian Bureau of Mines (IBM) under the ministry of mines to enter into an MoU with Isro to utilise its space applications for monitoring mining activity and study its impact to protect the environment,” he said.
The ministry has called for a meeting in this regard in New Delhi on October 1, where officials of Isro have been invited to work out modalities, Kumar told FE on the sidelines of an international mining conference, organised by the Federation of Indian Mineral Industries and mines ministry. IBM is engaged in regulation and scientific development of mineral resources and protects environment of mines other than coal, petroleum and natural gas, atomic minerals and minor minerals.
It may be recalled that widespread illegal mining in Karnataka and Goa led to the closure of mining in both states in recent years. The matter led to the intervention of the Supreme Court and its body the central empowered committee recommending suspension of mining and reforms in the sector. While mining has resumed partially in Karnataka, it is yet to start in Goa.
The city-based space agency will enhance its satellite capacity to meet the needs of the mining sector in coordination with states.
Kumar said the ministry has asked IBM to have a mobile app to take production figures from all mining lessees in a transparent manner. He said the ministry has floated request for proposal for appointing a consultant to carry out an airborne survey spread over 800,000 sqkm to identify new mineral deposits. Over three years, detailed geo-physical and electro-magnetic surveys will be conducted to identify new deposits. Based on the exploration studies, new mining deposits will be discovered in the next three to seven years, he said.
