Mechanisms and procedures to remove space debris are to be developed in the next future. The general problem of dynamics for a system formed of a remover space vehicle and a removed object is treated. Particular cases of tethered systems are in correlation with the TERESA concept. A model for a remover vehicle is proposed, provided with a remote controlled tethered subsystem to be connected with the removed object. The motion of deployment of a system

The present paper is an attempt to find definite analogies between some outstanding features of the magnetic fluids and the magnetic bacteria, as model and experimental levels. An ap-propriate study of the common and complementary features could conduct to the idea of gen-erating some common systems / aggregates. A living system – a culture of magnetic bacteria could be “coupled” with a magnetic fluid system. The structure of the latest could

The concept of an Central, Eastern and South Eastern countries Network for Education and Research in Space Science and Technology is given. Appropriate analysis of naitonal space developments of the countries in the region directed to a common system for higher education and related research projects of regional relevance.

Starting from a stati spherically symmetric solution of the Einstein's field equaitons in the second approximation in the perfect fluid scheme, in the exterior of the source, the corresponding metrics depend on a dimensionless parameter alpha. Taking the Sun for the source, the influence of alpha on the classical Solar System tests of the general relativity is estimated, the only alpha-dependent being the Shapiro radar-echo experiment. performing

A short-range experimental setup to determine the 1+e inverse square law in terms of Yukawa potential, developed in GRL Bucharest, is described. The gravitational dynamic field is generated by a mass quadrupole magnetically levitated. The detector is resonant Al5056 multipole. The noise damper is magnetofluidic assisted.

By means of fourth order tensor linearization, a practival formula to calculate the total energy released in a transient gravitational source event is given. A classification of terrestrial sources of gravitational radiation is given (earthquakes, thermo-nuclear explosions).
