Orbital Space Plane: capsule or wings? - Bad Astronomy and Universe Today Forum It's starting to look like an orbital tether could be easier to develop and build than a heavy cargo spaceplane, and once you have one tether in place it's much easier to build additional tethers. Has anyone thought of a spaceplane that could be launched lie a plane as well as landed like one? I woudl think that something like this would be much cheaper and more readily buildable than an OSP modeled after the Shuttle. www.bautforum.com /showthread.php?t=6615   (3717 words)

Binary Stars Eclipsing binaries are systems in which the orbital plane is oriented exactly edgewise to the plane of the sky so that the one star passes directly in front of the other, blocking out its light during the eclipse. The binary nature of the system is deduced from the periodic doppler shifts of the wavelengths of lines seen in the spectrum, as the stars move through their orbits around the center of mass. Spectroscopic binaries are systems in which the stars are so close together that they appear as a single star even in a telescope. astrosun2.astro.cornell.edu /academics/courses/astro201/binstar.htm   (307 words)

Flat rings - Bad Astronomy and Universe Today Forum The satellites are in the same orbital plane for the same reason the planets are: Angular momentum must be conserved. I think the main reason for the rings to be so flat and at equatorial plane is the pole flateness of Saturn itself. Well, presumably the objects that were torn apart to form the rings were already orbiting in the equatorial plane. www.bautforum.com /showthread.php?t=12932   (1348 words)

Inclination- Zoom Astronomy Glossary Orbital Inclination of the Planets in our Solar System Inclination is a measure of how the plane of an orbit is tilted with respect to the plane of the ecliptic. An orbit that lies on the plane of the ecliptic would have an inclination of zero degrees; higher numbers indicate more inclined orbits. enchantedlearning.com /subjects/astronomy/glossary/Inclination.shtml   (164 words)

Zoom Astronomy Glossary: O Orbital inclination is the angle between the plane of an orbit and the plane of the ecliptic. Obliquity is the angle between the plane of a planet's orbit and that of the planet's equator.

The Moon - Zoom Astronomy There are librations due to variations in the rate of the Moon's orbital motion (longitudinal libration) and to the inclination of the Moon's equator with respect to its orbital plane (latitudinal libration). The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (called regolith). Libration is a rocking movement of the Moon. www.enchantedlearning.com /subjects/astronomy/moon   (1475 words)

libration concept from the Astronomy knowledge base The much larger optical librations are due to variations in the rate of the Moon's orbital motion, the obliquity of the Moon's equator to its orbital plane, and the diurnal changes of geometric perspective of an observer on the Earth's surface. Physical librations are due to variations in the rate at which the Moon rotates on its axis. Libration is described as latitudinal, longitudinal and diurnal. www.site.uottawa.ca:4321 /astronomy/libration.html   (215 words)

Zoom Astronomy Glossary: L There are librations due to variations in the rate of the Moon's orbital motion (longitudinal libration) and to the inclination of the Moon's equator with respect to its orbital plane (latitudinal libration). Libration is a rocking movement of the Moon. Librations cause us to view the Moon from different angles at different times, enabling us to see about 59 percent of the Moon's surface from Earth, even though the same side always faces us. www.enchantedlearning.com /subjects/astronomy/glossary/indexl.shtml   (2571 words)

Amazon.com: So You'd Like to... Understand Orbits in Science Fiction Orbital mechanics were first derived by Kepler ( 'Epitome of Copernican Astronomy & Harmonies of the World (Great Minds Series)') and a more general solution was later provided by Newton ( 'The Principia (Great Minds)'). The inclination of the orbit is measured in relation to the equatorial plane; thus, an equatorial orbit lies on that plane and a polar orbit is perpendicular to the equator. The eccentricity indicates the degree to which an orbit deviates from a perfect circle (which has an eccentricity of 1.0), so a large eccentricity means that the perigee and apogee are very different. www.amazon.com /exec/obidos/tg/guides/guide-display/-/2CMRGOY1ZWIIA   (2571 words)

Encyclopedia: Spring In ancient Greece and other early civilizations, astronomy consisted largely of astrometry, measuring positions of stars and planets in the sky. Axial tilt is an astronomical term regarding the inclination angle of a planets rotational axis in relation to its orbital plane. In astronomy, the vernal equinox (spring equinox, March equinox, or northward equinox) is the equinox at the beginning of spring in the northern hemisphere: the moment when the sun appears to cross the celestial equator, heading northward. www.nationmaster.com /encyclopedia/Spring   (1924 words)

Einstein's Theory of Relativity - Scientific Theory or Illusion? The measurement of small angles in astronomy, such as diurnal aberration, close to the horizontal plane is difficult and insecure because of atmospheric and other influences. If we disregard the aberration caused by the movement of the solar system, then we are left with the annual aberration due to the orbital motion of the earth around the sun and the diurnal aberration due to the rotation of the earth. 22.2 the course of rotational velocity is opposite to that of the orbital velocity, so that the total aberration is the difference between the annual and diurnal aberration, as shown in Fig. users.net.yu /~mrp/chapter22.html   (1924 words)

ESLAB36 proceeding This requirement also makes space mission very attractive, since only they can ascertain observations over several planetary orbital periods without significant interruptions. In order to produce transits, it is of course necessary  that a planet-star system orbits in a plane that is within a small angle to the line of sight.

Astronomy - A new class of exoplanet - Francis Reddy Team member Geoff Marcy of the University of California at Berkeley told Astronomy that, after taking into account the way the system's orbital plane tilts toward us, the planet likely weighs in at roughly 25 Earth masses. However, the star is brighter than Gliese 436, and temperatures on the planet's sunlit side likely hover around 2,200° F (1,500 K). Only one other planet has been found around a red dwarf (Gliese 876), but the enormous number of these stars suggests exoplanets aplenty. www.astronomy.com /asy/default.aspx?c=a&id=2430   (183 words)
