Brownlee and Bradley report that one IDP from the NASA sampling contains tochnilinite, a mineral that appears only in a specific class of meteorites, suggesting a common asteroidal
source for the IDP and these meteorites.
Andrew's astronomical interests involved computing (used for lunar and asteroidal
occultation predictions and determining lunar limb profiles); low-light imaging using several generations of image intensifier; video recording (both vidicon and CCD); precision timing of astronomical phenomena (GPS and time insertion from standard radio-time signals); meteors and fireballs; occultations involving a range of small solar system bodies; and solar eclipses.
Using predictions produced by the European Asteroidal
Occultation Network and circulated by Andrew Elliott, amateurs are now using highly sensitive video cameras to record occultations.
Dr Miles pointed to a grazing lunar occultation of 9 Geminorum occurring on August 7, with the track of the graze crossing Kent, and to an asteroidal
occultation of the mag 2 star Delta Ophiuchi, occurring on July 8, the track crossing much of Europe, but not the UK.
Throughout the 1970s the Minor Planet Center, also based in Cambridge, was handling an ever-increasing volume of measurements of asteroidal
positions and computing their orbits.
They draw upon thermodynamic explosions, asteroidal
activity, fluid turbulence, insect behavior, natural selection, gravity, and other natural phenomena to create sculptures, drawings, paintings, videos, sound art, gadgets, and installations.
Earth s growth via asteroidal
collisions, formation of the metal core and a first solid crust, and the delivery of volatiles such as water.
The new research reveals that asteroidal
collisions not only severely altered the geology of the Hadean eon Earth, but likely also played a major role in the subsequent evolution of life on Earth as well.
209P/LINEAR was discovered as an apparently asteroidal
object of 18th magnitude on 2004 February 3.
The following asteroidal
occultation events were attempted:
Speakers will present a range of research topics, including mature space transportation, extraterrestrial prospecting, lunar and asteroidal
manufacturing processes, robotics and tele-operations, closed environment life support systems, space solar power and energy, and off-planet property rights.

impact: Atmospheric injection, benthic topography, and the surface wave radiation field.
