  2. TNA-1500 or RT-64 radio telescope: D = 64 m, full-swing parabolic reflector, minimum working wavelength = 1 cm, total mass =3800 t, mirror mass = 800 t, secondary mirror D = 6 m area of 1500 m². The construction of the telescope began in 1969. He joined the work in 1979. Manufacturer: Special Design Bureau MEI (OKB MEI). Large radio telescopes with a diameter of 64 m (TNA-1500) were created to support scientific programs. One (TNA-1500Mo) is located in Bear Lakes on the branch of OKB MEI 17km from Moscow with coordinates of 37 degrees 57 minutes east longitude and 55 degrees 52 minutes north latitude. A similar radio telescope (TNA-1500K) is located at the branch of OKB MEI Kalyazin (180 km north of Moscow) with coordinates of 37 degrees 53 minutes east longitude and 57 degrees 13 minutes north latitude. Both radio telescopes are connected geodesically, informationally, and organizationally can be a single complex that optimally provides a solution to a number of problems in the interests of various consumers. Radio telescope TNA-1500 (RT-64) Multipurpose microwave telescopes with a diameter of 64 m are designed for: - fundamental astronomical research, - space exploration, - receiving information signals from spacecraft from deep space, - spacecraft control in deep space. - functional application as part of the ZRT-64 ground-based radio telescope of the ground-based shoulder of the ground-space radio interferometer of the Radioastron project in the frequency ranges 0.327; 1.66; 4.85 GHz and 22 GHz (90 cm, 18 cm, 6 cm and 1.35 cm) for work on the Radioastron project. http://www.okbmei.ru/innovation_3.html

  4. PS (eyewitness) Luna 9 was an uncrewed space mission of the Soviet Union's Luna programme. On 3 February 1966, the Luna 9 spacecraft became the first spacecraft to achieve a survivable landing on the celestial body. The pictures from Luna 9 were not released immediately by the Soviet authorities, but scientists at Jodrell Bank Observatory in England, which was monitoring the craft, noticed that the signal format used was identical to the internationally agreed Radiofax system used by newspapers for transmitting pictures. The Daily Express rushed a suitable receiver to the Observatory and the pictures from Luna 9 were decoded and published worldwide. The BBC speculated that the spacecraft's designers deliberately fitted the probe with equipment conforming to the standard, to enable reception of the pictures by Jodrell Bank.
  5. https://en.wikipedia.org/wiki/Lovell_Telescope One of the most notable developments came in 1946 with the introduction of the technique called astronomical interferometry, which means combining the signals from multiple antennas so that they simulate a larger antenna, in order to achieve greater resolution. Astronomical radio interferometers usually consist either of arrays of parabolic dishes, arrays of one-dimensional antennas or two-dimensional arrays of omnidirectional dipoles. All of the telescopes in the array are widely separated and are usually connected using coaxial cable, waveguide, optical fiber, or other type of transmission line. Recent advances in the stability of electronic oscillators also now permit interferometry to be carried out by independent recording of the signals at the various antennas, and then later correlating the recordings at some central processing facility. This process is known as Very Long Baseline Interferometry (VLBI). Interferometry does increase the total signal collected, but its primary purpose is to vastly increase the resolution through a process called aperture synthesis. This technique works by superposing (interfering) the signal waves from the different telescopes on the principle that waves that coincide with the same phase will add to each other while two waves that have opposite phases will cancel each other out. This creates a combined telescope that is equivalent in resolution (though not in sensitivity) to a single antenna whose diameter is equal to the spacing of the antennas furthest apart in the array. A high-quality image requires a large number of different separations between telescopes. Projected separation between any two telescopes, as seen from the radio source, is called a baseline. For example, the Very Large Array (VLA) near Socorro, New Mexico has 27 telescopes with 351 independent baselines at once, which achieves a resolution of 0.2 arc seconds at 3 cm wavelengths. The world's largest physically connected telescope, the Square Kilometre Array (SKA), is planned to start operations in 2025
  6. Scenery - NRAO Karl G. Jansky Very Large Array The VLA or "Jansky Array", managed by the National Radio Astronomy Observatory (NRAO) consists of 27 independent radio telescope dishes, each with a diameter of 82 feet and weight of over 200 tons. Each antenna is found along the three arms of a track shaped in a Y configuration measuring 13 miles long. Using the rail tracks that follow each of these arms the antennas can be physically relocated to a number of prepared positions. At one point, the arms intersect with U.S. Route 60 which passes right through the middle of the array. It has been featured in numerous films, such as Armageddon, Independence Day, Terminator Salvation, a Bon Jovi music video, and was featured most prominently -and correctly- in the Carl Sagan novel Contact, as well as the film of the same name.
  7. Once again, thanks very much everyone for yours kind words.

    Nice set. I love Super UltraWide screen! How looks cockpit?
  9. Jan Kees! Thanks very much for yours kind words. I am a very grateful and satisfied user of BlueSky scenery. I have download all their scenery - huge areas of AZ, CA, CO, ID, NM, NV, MT, OR, UT, WA, WY - 360 Gb. It is outstanding. Excellent scenery, and runs nicely on my average system. I had much rather be flying over the real things vs computer created toy houses.
