“我找对了老公”——刘伯明妻子张瑶访谈

张瑶的笑容和刘伯明的极其相似,安静而活泼、踏实又幸福,俨然成了舒服的自处。自得其乐的人说起话来也娓娓道来,慢慢的、淡淡的,不经意间,已然是篇美好的故事:"我们俩是老乡,又是一所中学的,他比我高两届。我母亲当时是中学校长,刘伯明高二时,母亲代过他们班语文课,当时他就给母亲留下了很深的印象。后来考上飞行员也是我母亲送他去的。从那之后的五六年间,他一直和我母亲保持通信,汇报学习和工作,谈人生、谈理想。有一次,我母亲就问他有对象没,想找个什么样的。他说还没有,找个能独立理家的就行。"说到这儿,张瑶的脸上多了一抹灿烂。     

四爻——六四

六四,括囊,无咎,无誉——扎起口袋而没有灾难,是因为谨言慎行,所以没有灾害。洞穴生活和夜行性哺乳动物在幸运地度过了“撞击冬天”,随即大量繁殖,一支迁居到树上的哺乳类,成为原始的灵长类,形似松鼠。45．5岁（5000万年前）～现在。随着地球气温的逐渐上升,原始灵长类逐渐大型化。大约在4800万年前,出现最早的猿类——假熊猴。它们的嘴脸很长,朝前的双眼能看到立体事物,容貌酷似现在的狐狸,长长的尾巴可缠绕在树上,体重约5千克,与大猫差不多。主要分布在北美。当时的北美与欧洲是相连的,而欧洲与非洲也是相连的。不久后,不知什么原因,地球的气温开始下降,猿类向非洲迁移,身体也变得更大。为了增加生活空间,逐渐到地面生活。出现了黑猩猩。

放飞时代梦想 续写“巡天”情缘 专访中国航天员科研训练中心书记董重庆

文化是一种历史现象,它伴随人类社会而产生,是人类历史文明的产物。对一个团队而言,文化不仅是这个团队在长期社会生活中日积月累形成的一种相对稳定的生活方式、思维方式、一种规范和行为,而且代表了这个团队的精、气、神。古有子贡问政,子曰:"足兵,足粮,民信之。"于斯三者,逼不得已而去之,孔子留"信"。放之今日的企业形象、企业管理中,此"信"可属文化,其地位即是那"可载舟,可覆舟"的汪洋动力。由此可论,成功的普遍特点应该是有意识的对内部文化进行创建。中国航天员科研训练中心,已走过40光辉历程。在她不断发展壮大的同时,今天已逐步形成独具特色的巡天文化。作为中心管理另一只无形的"手",巡天文化在思想上为中国的载人航天事业保驾护航。2008年4月1日,中国航天员中心迎来40华诞,本刊记者特约采访了中国航天员科研训练中心书记董重庆。

乾卦和人类飞天（中）

爻辞——九四九四,或跃在渊,无咎。孔子《象辞》中的说明：或跃在渊,进无咎也。或跃在渊,无咎,何谓也？上下无常,非为邪也。进退无恒,非离群也。君子进德修业,欲及时,故无咎。或跃在渊,自试也。或跃在渊,干道乃革。重刚而不中,上不在天,下不在田,中不在人,故或之。

On the stability of the track of the space elevator

A string moving with geostationary angular velocity in its radial relative equilibrium configuration around the Earth, reaching from the surface of the Earth far beyond the geostationary height, could be used as track for an Earth to space elevator. This is an old dream of mankind, originating about 100 years ago in Russia. Besides the question of feasibility from a technological point of view also the question concerning the stability of such a configuration has not yet been completely solved. Under the assumption that a proper material (carbon nanotubes) is available, making the connection possible technologically, we address the question of existence and stability of the radial relative equilibrium of a tapered string on a circular geosynchronous trajectory around the Earth, reaching from the surface of the Earth far beyond the geostationary height.     

On the Possibility of the Existence of Volatile Compounds in the Region of the Scott Crater on the Moon

In this paper, we analyze the illumination conditions, the thermal regime, and the possibility of deposits of volatile compounds existing in the vicinity region (NSR S5 region) near the southern pole of the Moon. It has been found that there are no permanently shadowed zones near the Scott crater and the NSR S5 region, though the temperature conditions allow the of compounds such as CH₃OH, SO₂, NH₃, CO₂, H₂S, C₂H₄, and water to remain stable relative to evaporation for a long time (≥1 Gyr). It has been also shown that compounds like CO and CH₄ cannot stably exist in these regions.     

Estimation of the current density and analysis of the geometry of the current system surrounding the Earth

The results of an investigation of the distribution of plasma pressure, pressure gradients, and magnetic field near the equatorial plane in the plasma ring surrounding the Earth under magneto-quiet conditions are presented. Observational data obtained during the international THEMIS mission are used. The picture of the distribution of transverse-current density near the equatorial plane was obtained under assumption of observing the magnetostatic balance condition at geocentric distances from 6 to 12R _E. In estimating the integral transverse current it was accepted that in daytime sector the magnetic-field minima on magnetic field lines are not localized in the equatorial plane. Estimates of the integral transverse current were obtained, which demonstrate the possibility of closing nighttime transverse currents at geocentric distances of up to ～12R _E inside the magnetosphere, which form a high-latitudinal continuation of the ring current.

Estimating the accuracy of the technique of reconstructing the rotational motion of a satellite based on the measurements of its angular velocity and the magnetic field of the Earth

The paper has studied the accuracy of the technique that allows the rotational motion of the Earth artificial satellites (AES) to be reconstructed based on the data of onboard measurements of angular velocity vectors and the strength of the Earth magnetic field (EMF). The technique is based on kinematic equations of the rotational motion of a rigid body. Both types of measurement data collected over some time interval have been processed jointly. The angular velocity measurements have been approximated using convenient formulas, which are substituted into the kinematic differential equations for the quaternion that specifies the transition from the body-fixed coordinate system of a satellite to the inertial coordinate system. Thus obtained equations represent a kinematic model of the rotational motion of a satellite. The solution of these equations, which approximate real motion, has been found by the least-square method from the condition of best fitting between the data of measurements of the EMF strength vector and its calculated values. The accuracy of the technique has been estimated by processing the data obtained from the board of the service module of the International Space Station (ISS). The reconstruction of station motion using the aforementioned technique has been compared with the telemetry data on the actual motion of the station. The technique has allowed us to reconstruct the station motion in the orbital orientation mode with a maximum error less than 0.6° and the turns with a maximal error of less than 1.2°.

Optimization of the trajectory of the spacecraft insertion into the system of heliocentric orbits

The possibility of the spacecraft insertion into the system of operational heliocentric orbits has been analyzed. It has been proposed to use a system of several operational heliocentric orbits. On each orbit, the spacecraft makes one or more revolutions around the Sun. These orbits are characterized by a relatively small perihelion radius and relatively high inclination, which allows one to investigate the polar regions of the Sun. The transition of the spacecraft from one orbit to another has been performed using an unpowered gravity assist maneuver near Venus and does not require the cruise propulsion operation. Each maneuver transfers the spacecraft into the sequence of operational heliocentric orbits. We have analyzed several systems of operational heliocentric orbits into which the spacecraft can be inserted by means of the considered transportation system with electric propulsion (EP). The mass of the spacecraft delivered to these systems of operational orbits has been estimated.
