New rocket projects start
http://www.sina.com.cn 2003/04/04 11:08  Shanghai Daily

  Chinese rocket scientists have initiated research programs designed to develop a variety of powerful, non-toxic and pollution-free carrier rockets which will be capable of putting heavy satellites and moon exploration devicessintosorbit.

  Long Lehao, chief commander of the launch vehicle of the Chinese Academy of Launch Vehicle Technology, said yesterday that scientists in China have begun research on key technology for the planned carrier rockets.

  Long, chairman of the Sciences and Technology Council of the academy, said that the plan to develop two types of engine systems for the rockets had won approval from the central government.

  With regard to the core technology for the rockets, the scientist said that China has the capability to develop a next-generation launch vehicle.

  "If the entire research and development project is approved by the Chinese government next year, it will take us only five to six years to develop the new rockets."

  "Hopefully, the new rockets will be ready for commercial launch on the right time," said the scientist.

  Based on China's existing Long March launch vehicle technology, the planned rockets encompass 14 varieties and have a launch capability of between 1.2 and 25 tons in low earth orbit, and 1.8 to 14 tons in geostationary transfer orbit, he said.

  "Liquid hydrogen and oxygen, which are non-toxic and environ-mentally-friendly, will be used as rocket propellant."

  The research and development programs will help China to catch up with developed nations in the launch vehicle field and improve its competitive edge in the international commercial launch market, he said.

  Moreover, Long said, they are also critical for China's future space programs, including a proposed manned mission to the Moon.

  China's existing launch vehicle is not powerful enough to send astronauts to the moon, he added.

  Long also renewed his appeal for building a launch site for the next generation rockets on China's southernmost island province of Hainan. The ideal location there can help boost cooperation and exchange with other nations, he added.
