Radio wave

If the Moon is not "rocking" on the earth observation, radio spectra and sent to the reflected pulse would have been quite the same. In fact, the difference, although small, is still there. Radio wave, reflected from the edge of the moon, which is close to the earthly observer, the Doppler principle will have a somewhat greater frequency and thus shorter than radio waves, sent to the moon.

International Space Station

In preparation for the palette of a backup of the first crew is the third crew, and the backup second - fourth.
Joint flights as the first phase of the International Space Station. June 17, 1992 between the U.S. and Russia signed an agreement on cooperation in the exploration of outer space for peaceful purposes.

Beginning of the space age

October 4, 1957 the USSR produced the launch of the world's first artificial satellite. The first Soviet satellite has allowed for the first time to measure the density of the upper atmosphere, to obtain data on the distribution of radio signals in the ionosphere, to work out the issues of the launch, thermal, etc.

International Council of Scientific Unions

Containers with scientific equipment for missiles supplied parachutes that ensure their safe return to earth. In 1957, 58gg. expect another surge in solar activity. It was during this period to better study the Earth and near-Earth space at the call of the International Council of Scientific Unions, scientists from all parts of the world have combined their efforts during the International Geophysical Year.

In June 1980

In June 1980, the space orbit was launched advanced manned transport spacecraft "Soyuz-T-2." Its flown cosmonauts Yuri Malyshev and V. Aksenov. The new ship can operate in four modes of descent - managed two (automatic and manual), and two ballistic (primary and backup). Compared with previous series of spacecraft "Soyuz" a new transport ship was equipped with the most sophisticated technical devices.

Flight of the station "Salyut-7"

Flight of the station "Salyut-7" in automatic mode lasted from October 2, 1984 in caretaker status.
The output of one of the blocks of radio station "Salyut-7" in February 1985 led to the loss of radio contact with her. As a result, the station became "silent" and ungovernable. Only the crew on board the station could conduct repair work.

Orbital Station

After braking propulsion system and its re-entry vehicle separation landed by parachute. Flight of the station in the automatic mode has been extended for another three months. During the entire flight time the station was continually focused on Land. Station Orbital parameters were mostly within the following limits: apogee 270 - 299 km, perigee 235 - 268 km, inclination 51.6 degrees, orbital period of about 89.8 min.

use the "Ruslan"

After accession to the decision of Spain to a total of 13 NATO countries have expressed their intention to use the "Ruslan". At present, the mechanism of development of the project: determination of the principles of providing aircraft, the choice of the holder of the contract, determining the need for intermediary companies, and choice of carriers, which will enter into a contract.

Peenemünde Opitz

A few seconds later the aircraft has reached a critical Mach number, and cut down Opitz engines. The aircraft immediately went into a steep dive from which Opitz had brought him a few meters from the waves of the Baltic Sea. After landing in Peenemünde Opitz reported that the wheels seem stuck. Later, it was calculated that the Me 163 reached a speed of 1125 km / h.

Shield volcanoes

Shield volcanoes grow in height gradually, as a result of repeated eruptions from the same vents. Although at present these volcanoes apparently, are no longer valid, they are likely to have formed earlier and have been active for much longer than any volcano on Earth. In this hot volcanic point on the Earth over time changed their position due to the gradual movement of continental plates, so that the "building" a very high volcano in each case, time is not enough.

distort the signals

The value of the degree and nature of the influence of the atmosphere, the origin of electromagnetic radiation through it from the Earth to emit natural resources from outer space is essential. It is especially important to know the effect of the atmosphere on the transmission of electromagnetic waves in the study of weakly emitting and reflecting poorly terrestrial formations, when the atmosphere can almost completely suppress or distort the signals that characterize the object under study.

Radio telescopes

It was totally unexpected, because the other planets revolve around its axis, according to its motion around the sun. Radio telescopes have also confirmed that Venus is much hotter than here on Earth, but the numbers were called all kinds of specialists. And absolutely nothing certain no one could say about the chemical composition of the Venusian atmosphere and its pressure.

In October and November 1941

Evgeniya Kuznetsova, honored worker of the plant, pensioner, came to the company in 1942.
"In October and November 1941, the factory was evacuated № 125 № 39 plant them. Menzhinsky from Moscow, which has teamed up with the plant № 125 them. Stalin. In Irkutsk the evacuees were placed in private houses apartments.

Operation of liquid rocket engines

DE engines at UC placed in the light of their tasks. Thus, control motors, located in the nose and rear fuselage, provide coordinate movements OK on all axes and control its position in prostanstva.
Operation of liquid rocket engines and their fuel supply to provide:
• Fuel tanks (main, auxiliary and complementary) with the means of pressurization, gas stations, temperature control, fluid intake in the weightlessness and the like;
• means of delivery of propellants to the engine management, including the gasification of liquid oxygen;
• means to maintain the temperature of oxidizer and fuel, as well as structural elements;
• fuel and gas fittings and pipes;

COP-OK

To characterize the extent and effectiveness of experimental testing at COP-OK, it suffices to note that the spent 189 sections of complex tests, have been identified and eliminated 21,168 comments.
More efficient test operations at COP-OK ensured a high level of automation of tests, which amounted to 77% of the total work. (For comparison - the level of automation of tests of the "Soyuz TM" was 5%.).

"Desert Storm"

Cheney was wrong, as wrong and those who took the decision to withdraw from the intelligence service. "Desert Storm" in full force demonstrated the arguments of defenders of strategic intelligence - the satellites are not able to replace the aircraft. The pendulum has swung in the opposite direction: there was talk of the need to re-commissioning of the SR-71 A.
