Not wanting to risk a failure of its lucrative Polar Satellite Launch Vehicle (PSLV) and to be doubly sure about the on-flight performance of the various subsystems, Indian Space Research Organisation (ISRO) has postponed the launch of the rocket carrying remote sensing satellite Resourcesat-2 by nearly a month.
‘A realistic date of launch could be estimated only by the end of this month as it depends on the results of tests that are being done to know the high temperature tolerance levels of a key component,’ according to an ISRO official.
The PSLV launch, scheduled for launch this week, was supposed to sling Resourcesat-2 and two other small satellites – Youthsat and X-Sat – into orbit. Remote sensing satellites like Resourcesat send back pictures and other data for various uses. The Youthsat, an Indo-Russian micro satellite, carries two payloads – one Indian and the other Russian. Singapore’s X-Sat is also a micro satellite.
