Orbital simulations are used to determine what orbital parameters (including orbital distance) produce the observations seen by astronomers.

Space stations typically require a regular altitude boost to counteract orbital decay (see also orbital station keeping).

They therefore have approximately the same orbital period as Neptune and follow roughly the same orbital path.

(iii) Any change of orbital position

His botched but riveting trial may be over, but the Bo Xilai show will go on.

However, perturbations cause the orbital elements to change over time.

BRUSSELS America s riveting presidential election campaign may be garnering all the headlines, but a leadership struggle is also underway in Europe.

It would have an orbital period of roughly 1.8 million years.

Nothing captures this moral vacuum more vividly than the recent television drama, Wo Ju ( Crowded Spaces ), which has been riveting Chinese audiences.

These are the squamous part, the orbital part, and the nasal part.

In contrast, molecular orbital theory has orbitals that cover the whole molecule.

STS 1 was the first orbital flight of NASA's Space Shuttle program.

(d) Other legal matters 1, including legal aspects of sub orbital flights.

(iii) Kilometres, minutes and degrees as the standard units for basic orbital parameters

It is a measure of the actual degree of cleanliness of the orbital zone.

But I think when you guys start buying tickets and flying sub orbital flights to space, very soon wait a minute, what's happening here, we'll have military fighters with sub orbital capability, and I think very soon this.

Musician and activist Bono accepts the 2005 TED Prize with a riveting talk, arguing that aid to Africa isn't just another celebrity cause it's a global emergency.

The required speed is called orbital velocity, and it varies with the height of the orbit.

This includes Pluto, which shares its orbital neighbourhood with Kuiper belt objects such as the plutinos.

He guessed the same force was responsible for other orbital motions, and hence named it universal gravitation .

The presence of Neptune has a profound effect on the Kuiper belt's structure due to orbital resonances.

If Λ 1, then the body will likely clear out the small bodies in its orbital zone.

In that case, the observing campaign should at least achieve an orbital accuracy allowing a future recovery.

The Russian Federation has established world records in the length of a human's stay aboard an orbital station and has developed, in the course of operating the Mir orbital complex, effective technologies for medico biological support during prolonged stays in outer space.

The first satellite (orbital) photographs of Earth were made on August 14, 1959 by the U.S. Explorer 6.

In perfect two body motion, these orbital elements would be invariant (just like the Keplerian elements would be).

The effects of orbital debris on space security and the urgent need for action were a major focus.

The square of a satellite's orbital period is proportional to the cube of its average distance from the planet.

Earth co orbits with 10,000 near Earth asteroids (NEAs), and Jupiter has 100,000 Trojan asteroids in its orbital path.

The United States supported the IADC orbital debris mitigation guidelines, and its agencies were well along in implementing them.

Accelerating a spacecraft to orbital speed requires more than 60 times as much energy as accelerating it to Mach 3.

Despite the widespread acknowledgement of the danger of orbital debris, Aldworth emphasized that the problem has not deserved sufficient attention.

(a) To promote and coordinate at an international level activities related to the discovery, tracking and orbital computations of NEOs

Musical innovator Andrew Bird winds together his trademark violin technique with xylophone, vocals and sophisticated electronic looping. Add in his uncanny ability to whistle anything, and he becomes a riveting one man orchestra.

The orbital elements given here are as of January 2000, but they are continuously changing due to solar and planetary perturbations.

(a) To promote and coordinate activities for the discovery, pursuit (follow up) and orbital calculation of NEOs at the international level

(a) Determine the orbital deflection of the asteroid as a result of the impact, to an accuracy of approximately 10 per cent

It goes to the nucleus accumbens, all the way up to the prefrontal cortex, orbital frontal cortex, where decisions are made, high level.

(e) The development and implementation of technical standards to define general requirements for mitigating orbital pollution caused by the exploitation of space technology.

This would happen if the riveting television images of the ongoing agony of Katrina's victims could ignite among all nations and among all peoples the recognition that we all share the duty to be our brothers' keepers.

At a depth equal to half the wavelength λ, the orbital movement has decayed to less than 5 of its value at the surface.

This is especially the case for aerospace objects that might be used for the transport of persons or cargo via orbital or suborbital flights.

And it will be sub orbital. And the reason it has to be sub orbital is, there is not solutions for adequate safety to fly the public to orbit. The governments have been doing this three governments have been doing this for 45 years, and still four percent of the people that have left the atmosphere have died.

A combination of lunar gravity, solar gravity, and the flattening of the Earth at its poles causes a precession motion of the orbital plane of any geostationary object, with an orbital period of about 53 years and an initial inclination gradient of about 0.85 degrees per year, achieving a maximum inclination of 15 degrees after 26.5 years.

At this time, all the known comets had an orbital period of seventy years and more, with an aphelion far beyond the orbit of Uranus.
