... Сегодня: 10 апреля 2016 г. [NASA] Американский спутник ACTS был выведен на геостационарную орбиту в 1993 г. Это был экспериментальный спутник, на котором испытывались новые телекоммуникационные технологии, в частности на нем было установлено оборудование для передачи сигнала в Ka-диапазоне длин волн. ... В прошлом году миссия спутника ACTS была закончена, и теперь космическое агентство NASA решило передать его консорциуму из нескольких американских университетов. ...

... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...

... Remote Sensing of Fire Intensity and Burn Severity in Forests of Central Siberia . ... Increasingly sophisticated and comprehensive estimates of burned areas and of active fire areas are being produced using satellite imagery. However, accurate regional estimates of fire intensity, ecosystem fire effects, and fire emissions to the atmosphere require development of accurate remote-sensing based methods for estimating the intensity of active fires and the severity of fire impacts. ...

Determination of the orbits and estimation of the masses of ADS 7251 and ADS 5983 ( Gem) Natalia A.Shakht, Elena A.Grosheva, Denis L.Gorshanov. ... For ADS 7251 we have used the observations of W. and O. Struve 1821­1878 years (see Fig. ... In the motion of ADS 5983 our astrometric observations have been shown perturbations with period from 5.6 to 6.1 years, which are repeated during all interval of observations and assumed the presence of unseen component with low limit of the mass equal to 0.2 M . ...

... Maps of six sources (0420+022, 0420-014, 1308+326, 1345+125, 1803+784, and DA 193) obtained with milliarcsecond resolution are presented and discussed, together with their broadband (1­22 GHz) spectra obtained on the RATAN­600 radio telescope at epochs close to those of the VLBI observations. ... The image (Fig. 5) shows that the source structure at 18 cm is compact, consisting of a VLBI core and two jet components, with the outer component lying 5 mas (30 pc) to the northwest of the core ( = 54 ). ...

... As then we removed from the Earth, we dived into a sky deeper and deeper. ... We saw immense red-hot spheres, liked suns, in illuminator of our spaceship. ... We saw our Earth, Mars, Mercury, and planets-giants, such as Jupiter, Saturn, Uranus and other. ... Also we saw a comet. ... The planet Upsilon was on our way. ... If we could speak the language of these two peoples, we could explain them what the war did on our home planet "the Earth", how many people were killed because of war conflicts. ...
