Indian space capability is very high.ISRO's first moon craft, Chandrayaan-1, is being built for launch next year. Chandrayaan-1 ("Moon Vehicle" in Hindi) costs the ISRO just 2% of its annual budget for a period of five years for this mission. The ISRO says the moon probe will map the lunar surface at resolutions down to 5 meters, for the first time in human history.
 
India to launch first navigational satellite in June

India plans to launch its first navigational satellite in June, a top official of the Department of Space (DoS) said today.

The first Satellite of Indian Regional Navigation Satellite System (IRNSS) constellation, IRNSS-1 will be launched by PSLV-C22, said DoS Secretary and Chairman of Indian Space Research Organisation (ISRO) K Radhakrishnan. According to ISRO officials, IRNSS is an independent regional navigation satellite system, designed to provide position accuracy of better than 10 metres over India and the region extending about 1500 km around the country.

“It is designed to provide an accurate real time Position, Navigation and Time (PNT) services to users on a variety of platforms with 24×7 service availability under all weather conditions,” an ISRO official said.

IRNSS provides two basic services — standard positioning service for common civilian users and restricted service for special authorised users, the official said
.

“We are planning for June launch,” Radhakrishnan told reporters after addressing a symposium on ‘Indian Remote Sensing Satellite (IRS) Series: A Saga of 25 years’.

IRNSS-1 would be tested in orbit for three-four months once it’s launched, he said. ISRO has planned to have a constellation of seven satellites under IRNSS.

Speaking at the event, marking the 25th anniversary of the launch of India’s first operational Remote Sensing Satellite IRS-1A, Radhakrishnan said India has planned 12 missions (both launch vehicles and satellites put together) in the next one year.

These include the Rs 450 crore Mars orbiter mission in October-November aimed at demonstrating India’s technological capability to reach Martian orbit and paving the way for future scientific exploratory missions, and GSLV-Mk III experimental venture.

The GSLV-Mk III is conceived and designed to make ISRO fully self-reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4500 kg to 5000 kg.

Radhakrishnan said India’s remote sensing satellites are able to take images with a resolution of less than a metre (0.8 metres to be precise, according to an ISRO official). This means in those images, the official said, even ground features which are a little less than a metre wide can be recognised.

Radhakrishnan said ISRO proposed to launch remote sensing satellites with 0.6 metre resolution in two years and 0.25 metre in five years.

Former ISRO Chairmen U R Rao and K Kasturirangan spoke about the origin, growth and emergence of India as a world leader in the realm of satellite-based remote sensing in the past 25 years, at the two-day symposium, organised by Indian Society of Remote Sensing (ISRS) in partnership with other professional societies.

India today has 11 functioning remote sensing satellites, some of which are serving the country as well as the global community, according to ISRS.

India now has the largest constellation of remote sensing satellites in the civilian domain, dedicated to three main themes — land & water, cartography, oceanography and environment, including meteorology and weather monitoring, it was noted.

Scientific payloads for India’s Mars Orbiter will be received in the end of this month for integration with Mars-bound spacecraft which is scheduled to be launched on November 27 this year, Indian Space Research Organisation (Isro) chairman, K Radhakrishnan has said.

The Mars Orbiter mission is the country’s most ambitious mission so far as it would be the first time that any Indian satellite would have gone as far as the Red Planet which is estimated to be about 54.6 million Kilometers away, taking a journey time of nine months for it to reach Mars.

Radhakrishnan said preparations are in full swing at Master Control Facility (MCF) in Hassan, in Karnataka, and the Deep Space Network (DSN) at Bylalu, about 35 Km from Bangalore.

The Mars Orbiter will carry onboard nine scientific instruments with a scientific objective to study the Martian surface, its atmosphere and sustainability of life.

The Mars orbiter will be placed in an orbit of 371 x 80,000 km around Mars and will have a provision to carry 14.49 kg of scientific payload on- board. (Initially, a 25 kg payload was planned, but it was later scaled down.)

ISRO had initially planned to use the Geostationary Satellite Launch Vehicle (GSLV) to launch a 500 kg Mars orbiter, but then decided to launch the mission on board Isro successful workhorse, the Polar-synchronous Satellite Launch Vehicle-XL (PSLV-XL) due to back-to-back failures of the GSLV in 2010. The PSLV was also used to launch India’s Chandrayaan-1 mission, the unmanned lunar mission which ended up with a breakthrough discovery of water molecules on the lunar surface.

The orbiter payload, the Liquid Apogee Motor (LAM) that will propel it to Mars and the rocket motor that will slow it down for Mars orbit insertion, will together weigh 1.35 tons.

According to the planned mission profile, the LAM will be fired six times to progressively raise the orbit of the Mars Orbiter around Earth before sending it on its 55 million Km journey to Mars, much like a slingshot used by farmers to shoo away birds and scavengers from eating crops.

According to the Indian space scientists, the Mars orbiter would be launched over a month before it begins its journey towards the red planet to give mission planners sufficient time to raise its orbit to gain the momentum required to propel the Mars Orbiter towards its destination.

The rocket engine on the Mars orbiter that will be used to slow it down for orbital insertion around Mars is capable of generating a 440 Newton thrust.

The space scientists had determined three launch windows for the mission: between November 2013 and January 2014; between Jan and April 2016; and between April and May, 2018.

Finally November 27, 2013 was chosen as the day as it would give the space scientists the first opportunity of taking a crack when Mas would be closest to Earth nine months later at a distance of 54.6 million Km.

The Mars mission would estimated to cost Rs450 crore and a budgetary allocation of Rs125 crore has been made specifically for it.

India will be the sixth country to launch a mission to Mars after the US, Russia, Europe, Japan and China.

ISRO now designing GEO Imaging Satellite called GISAT

The Indian Space Research Organisation, ISRO, is now designing a GEO Imaging Satellite called GISAT. It will be launched in 2016-17.

GISAT will carry a GEO Imager with multi-spectral imaging instruments. It will be placed in geostationary orbit of 36 thousand kilometers above the earth. The total expense on the project is 392 crore rupees.

The remote sensing satellites launched by ISRO revisit the same area once in every 2 to 24 days for geological mapping. GISAT will provide the best pictures of the entire Indian landmass every thirty minutes. This information was given in the Lok Sabha today.

India and the US have agreed to cooperate on future missions to the Moon and Mars after successful collaboration in Chandrayaan-1 lunar mission.

“Building on NASA’s collaboration in India’s highly successful Chandrayaan-1 lunar mission in 2008, NASA and ISRO agreed to explore further cooperative space exploration work, including future missions to the Moon and Mars.

“To this end the working group agreed to continue discussions in planetary science and Heliophysics to identify areas of potential cooperation,” Indian Space Research Organisation (ISRO) and National Aeronautical and Space Administration (NASA) said in a joint statement.”The value of bilateral cooperation was well reflected, for instance, through the inclusion of two NASA instruments on the successful Chandrayaan-1 lunar mission, which led to significant discoveries about lunar surface characteristics,” NASA Administrator Charles Bolden said at the fourth US-India Civil Space Joint Working Group meeting here.
According to the statement, existing cooperation, in the use of US and Indian earth observation satellite data, has produced information yielding a broad range of societal benefits including improved weather and monsoon forecasting, disaster management and response, improved agricultural and natural resource use and better understanding of climate change.
