The program of physical studies on the Vernov satellite launched on July 8, 2014 into a polar (640 × 830 km) solar-synchronous orbit with an inclination of 98.4° is presented. We described the complex of scientific equipment on this satellite in detail, including multidirectional gamma-ray detectors, electron spectrometers, red and ultra-violet detectors, and wave probes. The experiment on the Vernov satellite is mainly aimed at a comprehensive study of the processes of generation of transient phenomena in the optical and gamma-ray ranges in the Earth’s atmosphere (such as high-altitude breakdown on runaway relativistic electrons), the study of the action on the atmosphere of electrons precipitated from the radiation belts, and low- and high-frequency electromagnetic waves of both space and atmospheric origin.  相似文献

The results of measurements of fluxes and spectra carried out using the RELEC (relativistic electrons) equipment onboard the VERNOV satellite in the second half of 2014 are presented. The VERNOV satellite was launched on July 8, 2014 in a sun-synchronous orbit with an altitude from 640 to 830 km and an inclination of 98.4°. Scientific information from the satellite was first received on July 20, 2014. The comparative analysis of electron fluxes using data from RELEC and using experimental data on the electron detection by satellites Elektro-L (positioned at a geostationary orbit) and Meteor-M no. 2 (positioned at a circular polar orbit at an altitude of about 800 km as the VERNOV satellite) will make it possible to study the spatial distribution pattern of energetic electrons in near-Earth space in more detail.  相似文献

The spectrum analyzer AKR-X onboard the Interball-1 satellite at the beginning (August–October 1995) and at the end (August–October 2000) of satellite operation in perigees of its orbital motion recorded and analyzed electromagnetic emissions of the inner regions of the Earth’s plasmasphere in the frequency band 100–1500 kHz at distances of 1.1–1.8 R E. The observations have shown that the electromagnetic modes (the Z and LO modes escaping the magnetosphere) which are formed at the altitudes 600–4000 km are associated with the subauroral nonthermal continuum and with the recently discovered kilometric continuum. There are noticeable differences in the spectral character of these emissions during the minimum (1996) and maximum (2000) solar activity, when, as a rule, the LO mode escaping the plasmaphere and the continua are not present.  相似文献

For a reliable prediction of dose loads on a crew and its habitation environment, which, so far, cannot be calculated with sufficient accuracy, an experimental study of the dynamics of radiation situation characteristics in the modules of the manned International Space Station (ISS) is carried out. The results of prompt monitoring and individual dose control of the crews of seven basic missions in the period of flight from August 1, 2000, to October 28, 2003, are presented. This period of time coincided with the maximum phase of solar activity. On the basis of comparing the measurement data, it was shown that the value of an accumulated individual absorbed dose did not exceed the limits of readings of a two-channel standard R-16 radiometer. The power of the radiation dose absorbed by crew members lies within the range 0.017–0.02 cGy/day and mainly depends on the solar activity level.  相似文献

Depleted narrow (localized in longitude) regions (field tubes) in the plasmasphere, recently discovered in He+ radiation measurements on the IMAGE spacecraft, were first directly observed by the Magion-5 satellite. The low-density regions (notches) occupy <~ 10–30° in longitude and extend from L ~ 2–3 to the plasmasphere boundary in neighboring plasmasphere regions with larger densities. The Magion-5 data give evidence that in the low-density regions temperature is enhanced as compared to the neighboring denser plasmasphere regions. Formation of notches in the plasmasphere is, apparently, associated with AE intensification during weak magnetic storms, while strong magnetic storms usually result in the overall reduction of plasmasphere dimensions. However, even a strong magnetic storm on April 6–7, 2000 (max K p = 9-and min D st ~ ?290 nT), but accompanied by an isolated AE impulse, resulted in a density decrease only in the longitudinally limited post-midnight sector of the plasmasphere.  相似文献

The results of reconstruction of rotational motion of the Foton M-3 satellite during its uncontrolled flight in September 2007 are presented. The reconstruction was performed by processing the data of onboard measurements of the Earth’s magnetic field obtained by the DIMAC instruments. The measurements were carried out continuously throughout the flight, but the processing technique dealt with the data portions covering time intervals of a few orbital revolutions. The data obtained on each such interval were processed jointly by the least squares method with using integration of the equations of satellite motion relative to its center of mass. When processing, the initial conditions of motion and the used mathematical model’s parameters were estimated. The results of processing 16 data sets gave us complete information about the satellite motion. This motion, which began at a low angular velocity, had gradually accelerated and in five days became close to the regular Euler precession of an axisymmetric solid body. At the end of uncontrolled flight the angular velocity of the satellite relative to its lengthwise axis was 0.5 deg/s; the angular velocity projection onto the plane perpendicular to this axis had a magnitude of about 0.18 deg/s.  相似文献

The results of numerical simulation of the general circulation in the Titan’s atmosphere at heights from 0 to 250 km are presented, obtained using a new model based on numerical solution of complete equations of motion of viscous compressible gas at the temperature distribution given by an empirical model. The model uses no hydrostatic equation and, as compared with traditional models, has higher resolution in vertical and over horizon. The results presented differ from results of other models and agree with the vertical profile of the zonal component of wind velocity measured by the Huygens spacecraft. Interpretation of this profile is given, including its main peculiarity consisting in a nonmonotonic behavior at heights from 60 to 75 km.  相似文献

Using the global commons for “peaceful purposes” is agreed upon among states in principle but disputed in substance. While non-militarization has been superceded by the doctrine of non-aggression, the latter, as a necessary rather than sufficient condition for “peaceful purposes”, is tested to its limit by the pressing issue of space weaponization. An international treaty to plug the gaps of the Outer Space Treaty should be negotiated. This would require the prohibition of both weapons in outer space and anti-satellite weapons on Earth. The Draft Treaty on Prevention of the Placement of Weapons in Outer Space and of the Threat or Use of Force against Outer Space Objects, proposed by Russia and China at the Conference on Disarmament, is an effort in this direction. However, divided views are held on several issues arising from the draft treaty, e.g. the efficiency of the current regime of outer space law, definitions of “weapons in space” and “threat or use of force”, and verification. A primary reason for US opposition to the draft treaty are security concerns over its space assets. However, exercising the right of self-defense is excluded from the obligations of disarmament and this is explicitly affirmed in the draft treaty.  相似文献

The planar circular Hill’s problem is considered, as well as its limiting integrable variant called the Hénon problem, for which the original Hill’s problem is a singular perturbation. Among solutions to the Hénon problem there are a countable number of generating solutions-arcs that are uniquely determined by the condition of successive passage through the origin of coordinates—singular point of equations of motion of the Hill’s problem. Using the generating solutions-arcs as “letters” of a certain “alphabet”, one can compose, according to some rules, the “words”: generating solutions of families of periodic orbits of the Hill’s problem. The sequence of letters in a word determines the order of orbit transfer from one invariant manifold to another, while the set of all properly specified words determine the system’s symbolic dynamics.  相似文献

《证券法》的颁布与实施,为规范证券市场,使证券市场走向公开、公平和公正,减少股市运作的制度和行为风险,为保障投资者的合法权益,提供了法律保障。各国证券法为了保护投资者的投资热情,以保证证券市场的活跃,大都规定了维护市场“三公”,即公开、公正、公平的原则。他们的证券法律法规规定了有关民事责任的赔偿制度,如美国1934年的《证券交易法》中规定了操纵价格、短线交易、虚假陈述等的民事赔偿责任。因此,应该建立完善证券市场中的民事法律责任制度,在制定后续相应的证券法规和司法解释特别是在制定《证券法》实施细则应该规定具体的、具有可操作性的证券违约责任和侵权责任,补充和完善《证券法》规定的不足和欠缺。  相似文献
