India's bid to launch an advanced communications satellite into orbit for the first time by using a cryogenic engine has failed. The rocket took off as planned but the phase powered by the new engine failed to perform and deviated from its path. Cryogenic engines are rocket motors designed for fuels that have to be held at very low temperatures to be liquid. They would otherwise be gas. Officials say that only five countries in the world have this technology. Indian Space Research Organisation (Isro) Chairman K Radhakrishnan said that an investigation would now be held to find out what exactly went wrong. Scientists say the mission failed because control of the two engines controlling the satellite was lost, resulting in loss of altitude and velocity.
