Scientists find solutions to keep rockets working

Chinese engineers have determined what caused the failure of the second flight of China's largest carrier rocket, a Long March 5, in July and have come up with corrective solutions, according to the State Administration of Science, Technology and Industry for National Defense, which oversees the program.

The administration said in a statement on Monday on its website that a number of simulations, calculations and ground experiments were carried out and results point to structural abnormalities inside the turbine exhaust device of one of the first stage's liquid oxygen/liquid hydrogen engines.

The abnormalities caused a sudden loss of engine thrust, depriving the rocket of lift, the statement said.
