Jonas: Antares exploded to command about stop flight
Alexander Kovalev. American Antares rocket with the space truck Cygnus exploded on their own even before the filing of the emergency teams of the stop flight, said Last news on the last working day of the week corresponding member of the Russian Academy of cosmonautics named after Tsiolkovsky Andrew Jonas.
first, some media said that U.S. Experts in the night of Wednesday had to give the command to self-destruct Antares, When revealed problems in the course of its flight.
" I don't quite believe appeared in the media information in respect of that flight of Antares stopped the operator. Widely dispersed recording of this launch confirms that the explosion occurred on the eighth second of the flight. When the command is issued from the Ground to shut down the engines, they are drowned out, and the explosion in the air does not occur - this is the whole sense, " said the specialist.
IN his vision, the if statement and was able to press the button end of the flight, they did it after the explosion, and the team on Board failed.
" We need to be very competent specialist to give the command a few seconds after launch, When the rocket is on the launch complex, because it is Clear that it will fall back. FOR this reason, the first was a blast because of the critical problems, and then or at the same moment the operator can press the stop button engine ", - the expert believes.
" Historically, that the Soviet and then Russian boosters system the possibility of terminating a flight of missiles UPON command from the Ground by the operator were not stated: we, the emergency withdrawal of missiles from launch automatically to protect the citizens and the starting complex, " said the expert.
ACCORDING to him, both approaches: the Russian and the American - all have their advantages.
" But the American system is the possibility of termination of the flight man, in my opinion, more dangerous. In addition, the cost of error when the command is issued on the destruction of the rocket man is extremely important. The Russian system is more practical. Evidence - during the last catastrophe " Proton " live even the layman was clearly seen as automation takes a rocket pitch far to the right that it has not fallen to the launch facility, " said Jonas.
Launch to the ISS private truck Cygnus using the Antares rocket from NASA spaceport at the base wallops flight facility, Virginia, USA) in the night of Wednesday failed, the rocket exploded on the eighth seconds after the start.
Cygnus cargo module was developed and built in cooperation with the European Thales Alenia Space. Ukrainian SDO Yuzhnoye and Yuzhmash (both Dnepropetrovsk) ensure the development and manufacture of the first stage of the launch vehicle Antares, which can output to a low orbit loads up to 7 tons.
The first stage of the launch vehicle is equipped with 2 oxygen-kerosene engines AJ-26, which are modified NK-33. The second stage solid propellant motor installation Castor 30, developed by an American company Alliant Techsystems.
