The rocket carried 4 satellites into space, 2 Indian and one each from Argentina and Indonesia. Interestingly, one of ISRO's payloads, Space Capsule Recovery Experiment (SRE-1), expected to return to Earth 13 days after launch, will be the first test of its re-entry mechanism. This is a step towards ISRO's ambitious goal of designing and building a cheap reusable launch vehicle. ISRO is also planning a manned mission to the moon, Chandrayan-1, which is expected to use a modified PSLV rocket which was used for this launch. This successful launch comes close on the heels of the failed July 2006 GSLV lauch which had ended in an expensive fireworks display over the Bay of Bengal. Another GSLV launch is planned for later this year.
