Sriharikota (Andhra Pradesh), Feb 25 (IANS) An Indian rocket carrying seven satellites - the Indo-French satellite SARAL, world's first smart phone-operated nano satellite, a space telescope satellite and four other foreign satellites - Monday blasted off from the Satish Dhawan Space Centre here, around 80 km north of Chennai.
A little after 6 p.m., the rocket - Polar Satellite Launch Vehicle-C20 (PSLV-C20) - standing 44.4 metres tall and weighing around 230 tonnes hurtled towards the skies ferrying seven satellites to sling into orbit.
President Pranab Mukherjee and scientists at Indian Space Research Organisation's (ISRO) rocket mission control room intently watched the rocket's progress towards the heavens, escaping the earth's gravitational pull with a one way ticket.
ISRO officials are hoping that the agency's 101th space mission and also the first of the 10 planned for 2013 will turn out to be a grand success.
The PSLV-C20 rocket is expected to deliver its main luggage - the 407-kg SARAL (Satellite with ARGOS and ALTIKA) and six other foreign satellites 794 km above the earth.
The entire flight sequence - lift-off to the ejection of the seventh satellite - will take around 22 minutes.
The successful launch of the satellites will take ISRO's tally of launching foreign satellites to 35. ISRO started putting into space third-party satellites for a fee in 1999 on its PSLV-C2 rocket.
Since then India has been successful in launching medium-weight satellites for overseas agencies. Initially ISRO started carrying third-party satellites atop PSLv rockets as co-passengers of its own remote sensing/earth observation satellites.
In 2007, ISRO for the first time launched an Italian satellite - Agile - as a standalone for a fee.
India began its space journey in 1975 with the launch of Aryabhatta using a Russian rocket and till date, it has completed 100 space missions.
Interestingly the PSLV is carrying seven satellites for second time after having done so in September 2009.
However, the highest number of satellites put into orbit in one go by the PSLV rocket - 10 - was in April 2008.
Two of the SARAL satellite's payload (ARGOS and ALTIKA) has been supplied by the French National Space Agency CNES while the solid state C-band transponder is from ISRO.
The SARAL will study the sea surface heights and the data generated will be shared by both countries.
Indian space agency officials told IANS the data from SARAL will be useful for operational as well as research user communities in fields like marine meteorology and sea state forecasting; operational oceanography; seasonal forecasting; climate monitoring; ocean, earth system and climate research; continental ice studies; protection of bio-diversity; management and protection of the marine eco-system; environmental monitoring and improvement of maritime security.
According to ISRO, the SARAL satellite is the first under the Indian mini-satellite Bus-series 2 configured for 400 kg satellites.
The Indian space agency states this satellite frame is envisaged to be the workhorse for different types of operational missions in the coming years.
Among the other six satellites that PSLV-C20 would sling into orbit are two Canadian satellites - NEOSSat (Near Earth Object Space Surveillance Satellite), the world's first space telescope designed by Canadian Space Agency (CSA) and Sapphire satellite built by MacDonald, Dettwiler and Associates (MDA); BRITE and UniBRITE (both Austrian); STRaND-1 (Britain) and AAUSAT (Denmark).
Curiously the STRaND-1 (Surrey Training, Research, and Nanosatellite Demonstrator) is the world's first 'smart phone satellite' carrying Google Nexus One phone running on the Android operating system.
The 6.5 kg satellite is a British mission jointly developed by the University of Surrey's Surrey Space Centre (SSC) and Surrey Satellite Technology Limited (SSTL).
The phone will run several applications, including collection of data and photographing the earth with its camera.
Once all the satellite's own operating systems have been checked out, key system functions will be transferred to the phone's components to take control and operate the satellite, SSTL said on its website.
According to CSA, NEOSSat will detect and track asteroids and satellites circling the globe every 100 minutes and scanning space near the Sun to pinpoint otherwise almost invisible asteroids.
The satellite will also be useful in tracking resident space objects, including space debris.
On the other hand, Sapphire will look for resident space objects that include functioning satellites and space debris circling between 6,000 km and 40,000 km above the earth.
