Search for Aqueously Altered Materials on Asteroids

Icarus, 1998
Abstract The analysis of visible and near-infrared reflectance spectra of C-class objects has revealed the presence of features that appear to indicate a history of aqueous alteration on their surfaces. This result can provide constraints on our understanding of the early Solar System.

Search techniques for near-Earth asteroids

Vistas in Astronomy, 1990
Knowledge of the near-earth asteroids (Apollo, Amor, and Aten groups) has increased enormously over the last 10 to 15 years. This has been due in large part to the success of programs that have systematically searched for these objects. These programs have been motivated by the apparent relationships of the near-earth asteroids to terrestrial impact ...

SST asteroid search performance 2014–2017

2018 IEEE Aerospace Conference, 2018
From 2014 to 2017, the Lincoln Near-Earth Asteroid Research (LINEAR) program performed wide-area asteroid search using the 3.5-m Space Surveillance Telescope (SST) located on Atom Peak at White Sands Missile Range, N.M. The SST was developed by MIT Lincoln Laboratory (MIT/LL) for the Defense Advanced Research Projects Agency (DARPA) to advance the ...

Asteroid Scare Provokes Soul-Searching

Science, 1998
SCIENCE AND THE PRESSLast week, astronomers created a media storm by announcing that an asteroid could collide with Earth in 2028, only to revise the estimates hours later. To head off future false alarms, some astronomers are now calling for word of such threats to first go out to a small community of colleagues so they can come to a consensus before ...
