Tunguska Meteorite Expedition 1908-1998 -jubilee edition for advanced scientists

TASS (The Amateur Sky Survey) hopes to construct low-cost drift-scan cameras (equipped with CCDs) which could be operated by amateurs around the world to monitor bright objects (including NEOs) across a large section of the sky. Its home page is very rich and includes (among many other documents): including latest status report, detailed information about hardware and software design, with sample images, pictures of TASS hardware, collection of Technical Notes, digest of data available through FTP

Tycho Brahe Expedition 1998 - the Expedition is searching for the giant meteorite that hit Greenland on December 9, 1997. Images and text are transmitted via satellite daily and posted to this site (also in Danish).

UESAC (the Uppsala-ESO Survey of Asteroids and Comets) is a search for previously undetected comets in the vicinity of Jupiter; it is described in two papers (paper 1 and paper 2, from the home page of Gonzalo Tancredi)

Understanding the Leonid Meteor Storms - understanding these events is important because of the effect they have on the estimated 500 satellites in orbit.
