21. APEX/Intro
... Research . Projects . ... The name of the project APEX is a reduction from words " Active Plasma Experiments " . The core of the project are active experiments with injection of electron and (or) plasma beams from a board of the satellite with simultaneous registration of the phenomena, produced by interaction of injected beam with background plasma. ... Active experiments utilise modulated electron beam accelerator and source of modulated xenon plasma beam on the main spacecraft APEX. ...

... These trajectories have an initial flight from the Earth to a large distance (of about 1.5 million km), the following passive flight to the Moon's orbit, an approach to the Moon with a decrease of an energy of a particle (spacecraft) selenocentric motion to a negative value and the temporary capture in an elliptic orbit of the Moon's satellite. ...

25. A VLA Survey of the First Quadrant of the Galactic Plane at 1.5
... 96.1655Garwood+ We presented results from a continuum VLA snapshot survey of the galactic plane in the longitude range 0d < l < 90d at 1.5 GHz. Observations were taken every 0.5^o in longitude at b=0^o. Most fields are complete to about 30 mJy peak density. The positions, peak, and total flux density of 471 compact sources (<30") have been measured. ...

27. Completeness
Next: X--ray Quiet PMS Up: Contents Previous: Fits to Evolutionary . The X--ray selected PMS candidates may not constitute a complete list. The primary factor is the sensitivity limit, complicated by the vignetting in the field of the PSPC which was used to make the source list. ... In order to better understand the completeness of the X--ray data, photometry of every star in both regions was undertaken. ... The X--ray quiet sources are distributed evenly across the field (see Figure 8 ). ...

32. Determination of the relative orientation between radio and dynamical reference
... The experience of determination of the link between radio sources and dynamical reference frames is presented. To obtain this connection we used a series of very long baseline interferometry (VLBI) observations of the spacecraft Phobos-2 and angularly nearby quasars. ... The dynamical reference frame is determined by equator and equinox of these ephemerides. ... References . ... The relative orientation of the radio and dynamical reference frames can be described by a sequence of three rotations . ...

34. Orbital Properties of the Solar System
. Mars is "behind" the sun from the earth's point of view and is therefore not visible in the nighttime sky (i.e. its up in the daytime). Venus it at greatest elongation and appears in the western sky as a bright object for 2-3 hours after sunset .

37. http://www.eso.org/public/news/eso1148/kids/
... Astronomers have taken the best photos ever of a star that has lost most of its material to a vampire star! This picture shows the positions of a large star (shown in red) and the vampire star (shown in blue) in photos taken about 1.5 months apart, as they orbit around a common point. ... The new observations show that the larger star is a bit smaller than astronomers had previously thought. ... The smaller companion star then just eats whatever comes its way like a friendly vampire! ...

38. Orbits
... The force F of gravity between two objects of mass m and M, whose centres are a distance r apart, is given by Newton’s famous equation: . ... where the radius of the Earth is 6,400 km, and the orbit is 1000 km above the Earth’s surface. ... Centrifugal Force . ... For a satellite to stay in orbit, this centrifugal force must balance gravity. ... So, as an object with a given angular momentum moves inwards, gravity increases, but the centrifugal force increases faster. ... Energy Considerations . ...
