Space On a new Orbit The space progamme in India started off modestly in the 1960s, but has taken off on an exciting journey of late. The recent launch of yet another satellite, writes Roshesh. P, establishes India’s emergence as a signifi cant space and satellite power DPA 40 NDIA steps across the threshold of its 60th year of Independence, fi rmly securing another milestone in Iadvancing its space technology. The September launch of the GSLV-F04 put into orbit the Insat 4CR satellite, not just taking India’s satellite launching capabili- ties a notch higher in the world market, but also augmenting the country’s booming television and telecommunica- tion sectors. The Insat 4CR satellite will for the next 10 years provide direct-to-home televi- sion broadcasting, video picture transmis- sions and digital satellite news-gathering services from its geo-stationary orbit. The launch is also a pointer to India’s ambition to be a signifi cant player in the race for the $2.5 billion global satellite launch business. Even as it celebrates the success of the GSLV-F04, the premiere national space agency — the Indian Space Research Organisation (ISRO) — is preparing the DPA launch of the fi rst GSLV-Mark III series. SCANNING THE SKIES: For ISRO, 2007 has been a resounding success in determining its capabilities in high-end technologies Slated for launch in early 2009, it will arm ISRO with the competence to launch four- domestic satellite by an indigenously built country to access super-specialty medical tonne payloads into geo-transfer orbit. rocket in 1980, India has had an exciting care.
