Submission + - Apple to start making iPhones in India (bbc.co.uk)

vasanth writes: Apple is to start making iPhones in the southern Indian state of Karnataka, the state's government has said.

Ministers said Apple would start an initial manufacturing operation in the state, whose capital is the tech hub Bangalore, in April.

The tech giant has a 2% share of India's mobile phone market, well behind South Korean rival Samsung.

Submission + - ISRO launches six Singaporean satellites

vasanth writes: The Indian Space Research Organisation (ISRO) successfully launched six Singapore satellites on Wednesday, the Indian space agency also tested the fourth stage of its PSLV rocket, the PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.

The test to restart the fourth stage of the PSLV rocket would help India in its future launches while attempting to launch multiple satellites in different orbits. Restarting a rocket engine soon after it is shut off is a critical technology that has to be mastered. Once a rocket engine is activated, then the heat generated is very high. The trick is to cool it down in the space and to restart it at a short gap.

With the latest, India has launched a total of 57 foreign satellites for 20 countries, the Wednesday’s launch earned India 26 million euros.

TeLEOS-1 the primary satellite is the first Singapore commercial earth observation satellite. It was launched into a low Earth orbit for "remote sensing" applications. The satellites will orbit around the equator and gather data that will benefit those in the equatorial region. The satellites was put into a 550 kms circular orbit inclined at 15 degrees to the equator.

The next three satellite launches using the Indian PSLV rocket would be navigation satellites, they would be followed by some multiple satellite launches for other countries.

Submission + - ISRO launches Astrosat, India's first dedicated space observatory

vasanth writes: A few days after it celebrated the successful completion of a year around the Red planet by its first inter-planetary mission — the Mars Orbiter, the Indian Space Research Organisation (ISRO) on Monday launched its first dedicated multi wavelength space observatory into space, besides six satellites for Canada, Indonesia and the United States. Though the national space agency has launched satellites for Indonesia and Canada earlier, this is the first time ISRO is launching satellites for the United States.

ASTROSAT will observe universe in the optical, Ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum, whereas most other scientific satellites are capable of observing a narrow range of wavelength band. All major astronomy Institutions and some Universities in India will participate in these observations, ISRO said on its website, these include Tata Institute of Fundamental Research, Indian Institute of Astrophysics, Inter-University Centre for Astronomy and Astrophysics and Raman Research Institute.

Submission + - ISRO successfully launches satellite into geostationary orbit

vasanth writes: Indian Space Research Organization (Isro) on Thursday cleared all doubts on its cryogenic capabilities, successfully launching the Geostationary Satellite Launch Vehicle (GSLV-D6), placing GSAT-6, a 2,117kg communication satellite in orbit.

The GSLV D-6 is the second successful consecutive launch of the GSLV series with indigenous cryogenic upper stage. ISRO had on January 5, 2014 launch GSLV D-5, after a similar attempt failed in 2010.

For the country, ISRO perfecting the cryogenic engine technology is crucial as precious foreign exchange can be saved by launching communication satellites on its own. Currently ISRO flies its heavy communication satellites by European space agency Ariane.

ISRO has already perfected it's Polar Launching Vehicle for launching lighter satellites which has decades of success stories. It has already put 45 foreign satellites of 9 nations into orbit. ISRO is to put 9 satellites in space using PSLV launcher for the United States in 2015-2016.

Submission + - The Indian Space Research Organisation launches record five UK satellites

vasanth writes: India launched its heaviest commercial space mission ever with its polar rocket successfully putting five British satellites into the intended orbit after a flawless takeoff. With the overall mass of five satellites being about 1,440 kg, this launch becomes the "heaviest commercial mission" ever undertaken by ISRO and its commercial arm Antrix Corporation.

The workhorse of India’s space program, the PSLV is on a run of twenty five consecutive successful launches. First flown in 1993, the Polar Satellite Launch Vehicle, or PSLV, is by far India’s most-used rocket for orbital missions – accounting for thirty of the country’s 46 launches to date including Friday’s.

Submission + - India successfully test fires its heaviest rocket

vasanth writes: India on Thursday moved forward in rocket technology with the successful flight testing of its heaviest next generation rocket and the crew module . The 630-tonne three-stage rocket, Geo-Synchronous Satellite Launch Vehicle Mark III, carried active solid boosters, liquid core stage and a passive cryo stage and a crew module to test its re-entry characteristics.

This rocket is capable of doubling the capacity of payloads India can carry into space and it can deposit up to four tonne class of communication satellites into space. India also plans to use this rocket for ferrying Indian astronauts into space.

For India, ISRO the Indian space agency perfecting the cryogenic engine technology is crucial as India can save precious foreign exchange by launching heavy duty communication satellites by itself.

Submission + - India Successfully Launches navigation satellite 1

vasanth writes: India has successfully launched IRNSS-1C, the third satellite in the Indian Regional Navigation Satellite System (IRNSS), early on October 16. This is the 27th consecutively successful mission of the PSLV(Polar Satellite Launch Vehicle). The entire constellation of seven satellites is planned to be completed by 2015.

The satellite is designed to provide accurate position information service to users in the country as well as in the region extending up to 1,500 km from its boundary, which is its primary service area.

In Kargil war in 1999 the Indian military sought GPS data for the region from the US. The space-based navigation system maintained by the US government would have provided vital information, but the US denied it to India. A need for an indigenous satellite navigation system was felt earlier, but the Kargil experience made India realise its inevitability in building it's own navigation system. "Geopolitical needs teach you that some countries can deny you the service in times of conflict. It's also a way of arm twisting and a country should protect itself against that," said S Ramakrishnan, director of Vikram Sarabhai Space Centre, Thiruvananthapuram

Submission + - India launches five foreign satellites

vasanth writes: India has put into orbit five foreign satellites, including one built by France two from Canada and one each from Singapore and Germany. The PSLV (Polar Satellite Launch Vehicle) has so far successfully launched 67 satellites, including 40 foreign ones, into space. The PSLV costs about 17 Million USD and the cost is seen as a major advantage India has over other countries in terms of commercial launches. When talking about the cost of the project, the Prime Minister of India noted that the launch was cheaper than Hollywood film Gravity.

Submission + - Scientists aim to improve photosynthesis (cam.ac.uk)

vasanth writes: "Two new initiatives at the University of Cambridge aim to address the growing demand on the Earth’s resources for food and fuel by improving the process of photosynthesis.

Four transatlantic research teams – two of which include academics from Cambridge’s Department of Plant Sciences – will explore ways to overcome limitations in photosynthesis which could then lead to ways of significantly increasing the yield of important crops for food production or sustainable bioenergy.

Despite the fact that photosynthesis is the basis of energy capture from the sun in plants, algae and other organisms, it has some fundamental limitations. There are trade-offs in nature which mean that photosynthesis is not as efficient as it could be – for many important crops such as wheat, barley, potatoes and sugar beet, the theoretical maximum is only 5%, depending on how it is measured. There is scope to improve it for processes useful to us, for example increasing the amount of food crop or energy biomass a plant can produce from the same amount of sunlight."
