The delayed Earth Explorer CryoSat-2 satellite would be launched on April 8 following the resolution of a technical problem, the European Space Agency (ESA) said here Friday. CryoSat-2 was originally scheduled to be launched from the Baikonur Cosmodrome in Kazakhstan on February 25, but the launch was suspended due to a problem found with the second-stage propellent of the Dnepr rocket, which will carry the satellite into the space. Rocket designers later confirmed that the ratio of fuel to oxidizer of the second-stage engine had to be adjusted to improve its performance. CryoSat-2 was Europe's first satellite designed to explore the relationship between ice and climate change by monitoring the change of the earth's ice fields, ESA said. The satellite would provide precise measurements on variations in the thickness of floating marine ice as well as the vast ice sheets that overlie Antarctica and Greenland, it said.
