  * Bolide - (Astronomy): Definition   (Site not responding. Last check: 2007-10-20)
A bolide is a meteor, asteroid, or comet that hits the Earth (or other planet or moon) and explodes.
A meteor of considerable duration and brightness is known as a ; a fireball that breaks apart with an explosion is a bolide.
The term "fireball" is sometimes used for a meteor approaching the brightness of Venus; the term "bolide" for one approaching the brightness of the full Moon.

 Bolide - Wikipedia, the free encyclopedia
When used in the first sense, the bolide may explode either on impact with the Earth's surface or at a low altitude above it, creating a large impact crater.
It is a generic term that does not imply the nature of the impacting body, i.e., whether it is a rocky or metallic meteorite, asteroid, icy comet, etc. Some scientists suggest that a glancing collision with a planet about the mass of Mars, ca.
Since the Chicxulub bolide has been suggested as the cause of the extinction event that exterminated the dinosaurs 65 million years ago, bolides are frequently suggested as causes of major climate changes and mass extinctions.

The bolide presumably was caused by the disintegration of a fragment of an asteroid when it hit the terrestrial atmosphere at a speed of approximately of 19±3 km/s.
Besides demonstrating the meteoritic origin of the bolide of 4 January, the gathered data on speed, sound phenomena, the penetration of the material in the atmosphere and the persistent wake are clear evidence that we face one of the most important events of the past decades in this field in Spain.
These bolides are luminous phenomena produced when a fragment of comet or asteroid is disintegrating upon entrance into the terrestrial atmosphere or, on special occasions, it can be produced by the re-entry of satellite debris.

 BOLIDE IMPACTS
The K-T event occurred at approximately 65 Ma and is believed to be the trigger of the dinosaur extinction.
In fact it is the work of Alvarez et al 1980 on the K-T boundary that has generated the growing interest on whether these large bolide impacts could have influenced the history of life.
In order to have any basis for the proposal of a bolide impact as the trigger of the end-Triassic, or in fact any mass extinction, there are certain pieces of evidence, which need to be found.

Having concluded that the transfer of energy from a meteor fireball (bolide) to create the anomalous sounds had to be by means of electromagnetic radiation, my (Colin Keay) primary task was to locate its spectral region.

 Impact Model
Since 1980, bolide impacts (bolide is a term of ignorance, meaning any object from space [comet, asteroid, Klingon Warship]) have been considered prime suspects for the forcing mechanism of some or all major extinction events in the earth's history.
If the bolide hit in mid-ocean it was thought that it would produce a tidal wave (tsunami) 4 to 5 km high in the open ocean, but of much lesser height on the continental shelf.
If the bolide was 14 km in diameter and travelling at 38 km/sec, then it would have generated up to 670 Gigatons of water vapor.

 Introduction
There is no consensus on its definition, but we use it to mean an extraterrestrial body in the 1-10-km size range, which impacts the earth at velocities of literally faster than a speeding bullet (20-70 km/sec = Mach 75), explodes upon impact, and creates a large crater.
"Bolide" is a generic term, used to imply that we do not know the precise nature of the impacting body.
The general public is intensely interested in bolide impacts, in particular because a large one, Chicxulub (pronounced cheek-shoo-lube), has been implicated in the demise of the dinosaurs.

 Encyclopedia: Bolide   (Site not responding. Last check: 2007-10-20)
The term bolide (from the Greek βολις;, bolis, missile) can refer to either an extraterrestrial body that collides with the Earth, or to an exceptionally bright, fireball-like meteor regardless of whether it ultimately impacts the surface.
When used in the first sense, the bolide may explode either on impact with the Earth's surface or at a low altitude above it, creating a large crater.
Alexander Tollmanns bolide is a hypothesis presented by Austrian professor of geology Dr. Alexander Tollmann, suggesting that one or several bolides (asteroids or comets) struck the Earth at 7640 BCE (+/-200), with a much smaller one at 3150 BCE (+/-200).

Bolide is a portable, cross-platform software development framework of the object oriented component software variety, for building compound documents and other types of content centric component software.
Bolide lets developers factor graphs of code and data into cooperating autonomous parts, where these parts bind together at runtime based on dynamic typing, availability of components, and preference rules.
Bolide was started at Christmas 1999, and currently has the status of vaporware since no code will be written until a large portion of the design specs are written first.

The Bolide has been developed to counter the evolving threat of small low-signature targets; targets making evasive manoeuvres; and targets with a higher level of protection.
The new Bolide is faster than the earlier RBS 70 SAM with an intercept range from 250m to 8,000m and up to an altitude exceeding 16,000ft.
Although the primary role of the Bolide is the engagement of aerial targets, especially armoured helicopters, the shaped charge will penetrate about 200mm of conventional steel armour.

From the far reaches of space, a bolide (comet or asteroid), 3-5 kilometers in diameter, swooped through the Earth's atmosphere and blasted an enormous crater into the continental shelf.
The entire bolide event, from initial impact to the termination of breccia deposition, lasted only a few hours or days.
Another consequence of the bolide is that all ground-water aquifers were truncated and excavated by the impact.

 Oregon Star Party 1999: Space Debris Falls Near OSP, article by Bob McGown
The unusual rectangular bolide, seen on September 10th, 21:30 PST was in a similar orbit to the south, although it is doubtful that it is associated with the Russian rocket.
The rectangular bolide fell rapidly and did not seem to hit an ablation point where it would have dropped out of the sky at terminal velocity.
Initially, I thought it was a second stage of a rocket because it was flat and square and came in at a medium angle orbit.

Investigation of a series of large and well-observed bolide events (> 0.05 kton) have allowed for the first time an empirical determination of the amplitude-energy relationship for bolide infrasound.
In addition, examination of stratospheric wind effects on the measured signal properties show that the observed scatter may be reduced and the relationships improved, though this may be considered a secondary effect when compared to other source characteristics.
The new empirical bolide amplitude relationship is steeper and falls below similar curves for strictly point source, ground-level nuclear and high-explosive data.
