the US President Donald trump, obviously, the Charter to struggle with the pandemic coronavirus, wanted to surprise China and Russia with new weapons. And surprised physicists and scientists. He announced the creation, as he put it, super-duper missiles, which, as “he heard”, will be 17 times faster than the Russian and Chinese counterparts. Other details head of the White house was not called. But this was enough to amuse experts.
the Head of Roscosmos, Dmitry Rogozin, for example, reacted on Twitter jokingly: “well, No, against the super-duper missiles, we catch nothing. Surrender!”,
That is the message from the US are not scared. Why?
on October 4, 1957 when the USSR launched the first artificial Earth satellite, we experimentally confirmed the so-called first space velocity 7.91 km per second. Soviet rocket broke up the spacecraft to a speed that allowed him, using the force of gravity, to remain in a circular orbit.
the Speed of Intercontinental ballistic missiles of Russia and China, and other countries, including the United States, slightly less than the first space. After all, their task is not to send nuclear warheads into earth orbit and deliver the desired point on the earth’s surface
it is believed that to start the apparatus or insertion of the spacecraft need to reach a speed of 24-25 times the speed of sound (Mach 24-25). Now, the latest Russian hypersonic maneuvering nuclear warhead missile complex “Avangard” is flying at a speed of about Mach 20, which is about 6-7 kilometers per second. More about this in 2018, said President Putin. Today, the complex is already in service with the strategic Missile forces.
according to trump, the new American “super-duper” rocket will be 17 times faster than the Russian and Chinese ICBMs. That is, according to Trump, will be able to fly at a speed of 100 kilometers per second. In this case, it is better to use in the intergalactic wars. Because the earth’s orbit, such a rocket will not keep.
This is much more than the second cosmic velocity is 11.2 kilometers per second, which is sufficient to overcome the earth’s gravity. A body having a near Earth escape velocity, leaving Earth’s neighborhood and becomes a satellite of the Sun, says Wikipedia.
At this rate, by the way, not once, not twice, flew to the moon, Mars and Venus spacecraft of the USSR, the USA and other countries.
“Super-duper” rocket trump once again showed how far you can take away from the reality of the imagination of politicians and the ignorance of physics.
