Summary/Abstract

International Affairs: Mr. Zeleny, the U.S. has decided to stop space shuttle flights. Does this mean that the U.S. space program is going through a period of profound change? Academician Zeleny: Indeed, the Barak Obama administration confirmed in early 2010 its intention to stop space shuttle flights and to replace the Constellation Program by a new strategy in the field of manned space missions. It is planned to attract private firms to the development of technologies for delivering cargoes and astronauts into space and simultaneously to conduct research and development on the space infrastructure of the future, including new-generation rocket engines. And, only 5-10 years later, it was planned to begin work on the construction of a new super-heavy launch vehicle and spaceship for long-distance space flights.
