Time/Frequency Analysis of Terrestrial Impack Crater Records [PDF]
The terrestrial impact cratering record recently has been examined in the time domain by Chang & Moon (2005). It was found that the ˜ 26 Myr periodicity in the impact cratering rate exists over the last ˜ 250 Myrs.

Presolar grains are microscopic dust grains that formed in the stellar winds or explosions of ancient stars that died before the formation of the solar system.

The Dynamics of Meteoroid Streams [PDF]
Meteor showers are seen at regular and frequent intervals on Earth. They are caused by meteoroids (that is small dust grains) in a coherent stream, all moving on similar heliocentric orbits, burning up on encountering the atmosphere of the Earth. Such streams contain 1012 or more meteoroids, with the mass of the visible meteoroids ranging up to about 1

Nitric oxide (NO) is a critical indicator of energy deposition in the lower thermosphere because of its formational pathways. Thus, it is important to constrain sources of NO, such as meteoroid generated hypersonic flows below 95 km altitude.

Advancements in space exploration and sample return technology present a unique opportunity to leverage sample return capsules (SRCs) towards studying atmospheric entry of meteoroids and asteroids.

SPACE DENSITY DISTRIBUTION OF METEOROIDS OVER THE SPHERE WITH RADIUS 1 A.U.
Space density distributions of meteoroids over the sphere with radius 1 AU and the centre in the Sun were found for meteoroid masses greater than 10-3 g, 10-2 g and 1 g.

Meteoroid structure and fragmentation [PDF]
The physical composition and structure of meteoroids gives us insight into the formation processes of their parent asteroids and comets. The strength of and fundamental grain sizes in meteoroids tell us about the environment in which small solar system bodies formed, and the processes which built up these basic planetary building blocks.

Robotic Systems for Meteor Observing and Moon Impact Flashes Detection in Spain
A robotic observatory has been setup in the south-west of Spain with the aim to study meteoroids interacting with the Earth's atmosphere and meteoroids impacting on the Moon's surface.

Determination of meteoroid physical properties from tristatic radar observations [PDF]
In this work we give a review of the meteor head echo observations carried out with the tristatic 930 MHz EISCAT UHF radar system during four 24 h runs between 2002 and 2005 and compare these with earlier observations.
